A Theory of Evil

 

 

 

 

The Uniformity of Evil

 

 

Evil comes in many varieties. A typical list would include: genocide, murder, torture, terrorism, slavery, sadism, the sexual and physical abuse of children, slander, betrayal of trust, desecration of the sacred, disfiguring, maiming, and crippling. We might count as evil the willful destruction of great works of art or architecture, in addition to such standard examples as the extermination of innocent populations. Physical harm to persons is not always involved, though it often is, along with emotional pain. Given this variety, we might be tempted to suppose that the class of evil acts is irreducibly heterogeneous, united by nothing more than brute disjunction or family resemblance. That is, we might deny that there is any one feature common and peculiar to all evil acts. The concept of evil, it may be said, is just too vague and open-textured to admit of informative definition. We must accordingly accept the diversity of evil.

I shall suggest, to the contrary, that evil is a unitary quality common to all acts rightly classified as evil. Moreover, it is quite a simple quality, which is not to say that it is easily identified in practical life. My definition of evil, to get right to it, is that it is the intentional destruction of the good—but this will need some unpacking. First, destruction: by this I simply mean, “causing to cease to exist”. The world contains a certain entity or quality at a certain time and to destroy that entity or quality is to bring about its cessation. This may be done violently or insidiously, quickly or slowly. It is the opposite of creation: instead of causing something to exist, it removes that thing from reality. So destruction is explained through the notion of existence and its negation. It is therefore a highly general notion applicable a wide variety of cases—people, animals, artifacts, states of mind, social movements, bits of nature.

Second, the good: by this I mean any good state of affairs. Without going into the matter fully, the following list will serve our purposes (we could add to it if need be): life, happiness, knowledge, innocence, freedom, friendship, and aesthetic quality. If you think some of these items reduce to others, or should not be on the list of intrinsic goods at all, by all means amend as you see fit; the definition of evil will remain the same, even if its extension differs. I favor keeping the list fairly long and non-reductive, because I think that the good is best seen in all its variety; we don’t want theories that try to reduce every basic value to one (such as pleasure). Despite the variety of the goods, there is something they all having in common—that they are precisely good—and that is what matters to the definition of evil.

Third, intentional: by this I mean that the act in question must be intended in a certain way. If an agent destroys something good by accident, through no fault of his own, and is horrified by what he has wrought, he cannot be adjudged evil, merely unlucky. So we should say that an evil act is one that is intentional under the description “destruction of the good”: the agent foresees and intends the destruction of the good and acts as he does in order to bring this destruction about. He “knows what he is doing”. In a typical case he plans the destructive act and self-consciously carries it out.

Thus an evil act is one that involves an agent intentionally destroying what he knows to be good. The mental state of the agent incorporates the concepts of destructionand goodness—this is the content of his intention in acting. It is the intention that defines the evil agent. Is there a second-order intention associated with this first-order intention? Grice argued that communicative acts require a second-order intention—not only the intention to produce a belief in one’s audience, but also an intention that the first intention should be recognized by the audience. Thus the basic intention is transparent, not concealed and secret. In the case of the evil agent, there is also a second-order intention, but it is not a transparency intention—it is an opacity intention. The agent intends that his first-order intention should notbe recognized by observers (he may even try to shield himself from knowledge of his intention). The evil agent is trying to destroy the good, but he doesn’t want people to know that this is what he is doing, possibly including himself. Even if he feels safe in his actions, fearing no repercussions, he does not want it to be apparent that his aim is precisely to destroy something good. So he will often characterize his actions in other ways—say, by arguing that he is serving a greater good. I might put it by saying that there is always a level of shameabout evil actions, and hence a desire for concealment. The agent is not proudof what he does, even if he tells himself it is somehow necessary. For the agent has set about intentionally destroying what he acknowledges to be good, and this is not something he can happily admit. That is why there is often a degree of self-deception involved in evil actions (not so for virtuous actions). For this reason there will typically be a second-order intention to conceal the first-order intention. The easiest way to fulfill that intention is to commit the evil act secretly, away from prying eyes—as it might be, in a dungeon or concentration camp or in the dark. The evil agent is by nature deceptive; secrecy is his cover, his protection.

The conception of evil I am suggesting limits it to creatures capable of certain kinds of “sophisticated” attitudes. I doubt that animals are capable of evil in the sense I have defined, though they are certainly capable of impressive feats of destruction. Animals may maim or kill but they don’t do so with the kinds of intentions I have described (some of our primate relatives may have such intentions, in which case my claim applies to non-primate animals). They may cause great suffering and death but they do not do so under the description “destroy the good”. They just don’t have the concept. Evil is what results when a creature acquires such abstract concepts, so it is a uniquely human achievement. Perhaps, indeed, the very acquisition of the concept of the good (as well as the concept of destruction) is what opens the human species up to feats of evil not possible for other species. We do evil things precisely because we know what good is; we destroy the good because we apprehend things asgood. Evil thus requires a certain intellectual attainment. The necessity to conceal evil acts also requires a cognitive sophistication absent in other animals (possibly with certain exceptions). It is not that animals do less harm than we do—though that is doubtless true—but rather that the harm they do does not spring from evil motives and intentions.

Now we must see how the definition fits the various types of evil I have listed. Let’s start with a hypothetical example. Suppose a university administrator, call her Eva, receives a complaint against a distinguished professor, call him Carl. The complaint is completely fictitious, being motivated by malice and a bad grade. Eva knows this, but she also knows that taking disciplinary action against Carl will, in the current climate, score her political points, help with funding, and appease the radical feminists. She decides to initiate dismissal proceedings against Carl, fully aware that this will ruin his reputation, take away his livelihood, and prevent him from any further achievements as a scholar and teacher. She also knows that he cannot fight her actions legally because it would bankrupt him to do so. Eva thus uses her power, quite cynically, to destroy Carl in order to advance her political and personal goals. Carl is duly forced out of his position, becoming impoverished and bitter. I hope we can agree that Eva was evil in acting as she did, and the reason is clear: she intentionally destroyed something good. Carl was an innocent man, a good man, and also a productive and brilliant scholar. Eva destroyed his ability to work and teach, as well as his happiness and security, along with that of his family. She did so deceptively, unethically, and callously. Her evil actions fit the definition perfectly.[1]

Next consider an artist who is tired of being unfavorably compared to another artist, whose work is vastly superior. He decides to destroy the superior artist’s work, stealing into his studio one night and burning all his paintings. Let’s suppose that he manages to destroy every one of the great artist’s works and also to prevent him producing any more (he is so traumatized by the destruction). Now the second-rate artist gets more attention and makes more sales, with his main rival eliminated. Again, these actions are clearly evil, and they fit the definition perfectly: the evil artist has intentionally destroyed works of great aesthetic value for his personal gain and out of envy.

David is a bitter man and a failure in life. He lashes out at anyone he can, belittling and insulting people. His young son Patrick becomes a target of his ire because David cannot stand the thought that his son might succeed where he failed. He sets out to damage Patrick psychologically, even going to the extreme of raping his five-year old son. He succeeds in his aim and Patrick is so traumatized that he becomes a heroin addict and eventually commits suicide. Again, the evil is obvious, and again we can see why: David has destroyed Patrick’s innocence and happiness in order to satisfy his own warped needs. His express aim was to prevent his son from achieving anything good in life, including any chance of happiness: he destroys the good in order not to suffer the pangs of his own sense of failure.[2]

Terrorists bomb a city center, killing dozens of innocent men, women, and children. They do so because the people they have targeted practice a different religion from theirs and appear to be happy and prosperous doing so, making their own religion look shabby and regressive. Their aim is not just to kill and maim but also to undermine the peace of mind of people living in the city in question. Their actions are evil and for the usual reason: they have destroyed life, happiness, and peace of mind among the target population, because of their misguided religious zealotry.

The Nazis undertake a program of mass extermination against the Jews. Their motivation is that the Jews are far too successful in German society, owing to their intellectual and cultural superiority. The Nazis covertly acknowledge the qualities of the Jewish minority and wish to rid themselves of a people that challenge their sense of racial superiority. They accordingly murder six million Jews by means of starvation, gunshots, and poison gas. They are defeated before they can realize their project of total genocide, but they would have carried it through to the end if they could. No one can doubt the evil of the Nazis, and their actions clearly conform to the theory: they intentionally destroyed the good—life, well-being, culture, achievement—in order to gratify their own (shaky) sense of superiority.

Liz is a friend of Susan, who is also friends with Wendy. But Liz doesn’t like the friendship between Susan and Wendy; she wants Susan to herself. She decides to undermine the friendship between Susan and Wendy by telling lies about Wendy to Susan, to the effect that Wendy has been making advances to Susan’s boyfriend. Liz convinces Susan of this falsehood, using doctored photographs and what not. Susan consequently drops Wendy as a friend, causing her considerable distress. This is not evil on a grand scale, like the previous example, but it is evil nonetheless. Here the good that has been destroyed is friendship.

Iago sets out to destroy Othello, who is respected as a great general and honorable man (Iago’s reasons are obscure), by making him jealous. He succeeds in reducing the normally unflappable Othello to a blubbering heap and a murderer of Desdemona, his wife. Iago’s evil consists in this act of destruction, more of the soul than the body, in the case of Othello. Macbeth betrays the trust of King Duncan, murdering him while he sleeps, in order to advance his own ambitions, and then murders others to cover his crime. He doesn’t think Duncan is a bad king; on the contrary, he likes and admires Duncan. So he has knowingly destroyed something good. Judas betrays Jesus, despite believing him to be the Son of God, for fifty pieces of silver; he thus destroys the embodiment of goodness for a tawdry sum.

I don’t think I need to multiply examples any further: it is easy to see how the definition of evil I have presented works, and indeed it is an intuitive and natural way to characterize evil. The definition is simple and straightforward; and it offers a uniform account of what evil is. Are there any counterexamples to it? Someone might suggest that the definition does not provide a necessary condition for evil, since some evil consists in positively producing harm, not just removing the good. The evil of torture, say, is that it produces a lot of harm, either pain or injury. But I take it that this is just another way to phrase the theory under discussion: to produce harm is just to annihilate a good, i.e. the good of notbeing harmed. Harms are defined relative to goods: for example, pain is bad because it is good not to be in pain. The trouble with stating the theory in terms of harm is that it loses generality—not all cases involve an intention to harm. The envious artist was not attempting to harm his rival exactly, though he did; his intention was to destroy the good—the harm to his rival was just a by-product.  The same can be said of the desecration of sacred sites or buildings. The harm formulation gets the emphasis wrong: the evil agent recognizes the good in something and seeks to destroy it despite this; he is not just out to do harm. A run-of the-mill thug might be out to create harm by punching anyone within range, but he is not evil in the sense I am trying to capture. Evil is the intentional abolition of the good, recognized as the good. Iago, say, is not interested in bringing down some undistinguished nobody; what incites him is Othello’s distinction—the good that he embodies. And what marks Judas out is not just a betrayal of any old goat-herder from Palestine, but the fact that he betrayed the Son of God (allegedly). The harm caused might be the same in both cases, but the evil agent is doing more than just maximizing harm—he is destroying that which is indisputably good. It is true that one way to destroy what is good is to cause harm, as in crippling an athletic rival, but the evil resides in the negation of goodness, not in the harm as such. Nor is it clear that negating the goodness of a person is always harming her: if a scientist reduces the intelligence of a rival by putting a chemical in her drink, this is definitely evil, but it is not clear that the target has been harmed—she might be quite happy having average intelligence. I might set out to make you happier by chemical means, so that you spend less time at home working, and more time out having fun—as a way to lessen your intellectual output. This would be evil, but it is not clear what harm I have done to you—you might even decide you want to change your life-style in that direction anyway. What if I introduce you to a very seductive partner so as to distract you from your important intellectual work—have I harmed you?

Now it might be claimed that the conditions are not sufficient for evil, since it is possible to intend to destroy the good for morally praiseworthy reasons. Thus we have vaccination and surgery—we remove a person’s tranquility and freedom from suffering by subjecting them to these procedures. Are dentistsnecessarily evil? The obvious answer is that the agent is aiming for the greater good of the patient, and rightly so: the short term removal of the good is justified by the long term creation of the good. It wasn’t that Iago believed that only by destroying Othello and Desdemona could he save the city of Venice from a terrible fate: he did not commit his harmful acts with a heavy heart, with everyone’s best interests in mind. So we should add that evil is the intentional destruction of the good all things considered—that is, when the destruction of one good is not justified by the production of a further good. Of course, this is not to deny that some evil agents use such justifications spuriously, as the Nazis did to excuse their genocidal actions. But in cases like dentistry it is clear that no evil is committed, since the intention is to produce long term dental goodness in the (temporarily) suffering patient. The dentist is promoting the good not negating it.

Let me return for a moment to the destruction of reputation, because I think it is particularly instructive. This does not involve physical harm or death, so it doesn’t fit a crude definition of evil as simply “causing suffering”. A person can no doubt suffer from the unjust destruction of his reputation, but that suffering does not pinpoint wherein the evil lies. The slanderer is taking aim at a manifest good and seeking to annihilate it: the good character or good standing of the person unjustly accused. Suppose the target’s reputation is well earned and fully justified—it is backed by undeniably good qualities. Then the slanderous accuser is attempting to negate this manifest good—say, with a view to preventing the person accused from gaining employment. The intention is precisely to destroy a human good—that is its exact focus. This epitomizes evil, perhaps more clearly than any other case, because the good that is destroyed is specifically targeted as such. It is close to another paradigm of evil—the intentional undermining of trust. If an evil agent sets out to gain the trust of another person, himself without evil intent, by encouraging such trust, with a view to betraying it later, she has attacked a deep and central human good—the ability to trust another person. A person treated in this way may never be able to trust again, which undermines many other human goods. The betrayer has destroyed something precious and precarious, and we rightly reserve our severest criticism for such actions. This is precisely what Iago and Macbeth do. It is particularly heinous because it specifically targets a central human good for annihilation. Just as a person values his good name, so he values being able to trust other human beings: to destroy these things is evil in the purest sense. Neither of these forms of evil is calculated to cause pain or death (though they may cause both of these things); what they are calculated to do is to take a certain kind of good from a person that is highly valued. Both involve depriving the target of normal social relations. The evil here consists in destroying a fundamental socialgood—being well thought of and kindly received, and being able to place one’s trust in another. Hence these are my paradigms of evil, not the usual cases of torture and murder—because they exemplify the abstract form of evil so clearly.

We need to make a minor amendment to the definition. I have been speaking of evil agents, but there are also those who are passively complicit in evil—bystanders or onlookers. There are not just those who do the deeds, there are those who allow them to be done. It is not only the agents of the action who are evil but also the observers of it: the wife who lets her husband rape his son, those who tolerate atrocities committed by others, people who make no protest when those with power persecute the innocent—the whole sorry crew of cowards, toadies, and the morally numb. These enablers of evil should also be included under the concept. It is easy to do so: just add “or those who tolerate the destruction of the good”. We thus recognize two categories of evil: active and passive.

We should also make a distinction between ideological evil and non-ideological evil. Iago and Macbeth are not evil ideologues, like Stalin or Hitler. They stop when the count of corpses reaches the double figures, and no general ideology drives their homicidal tendencies. But the evil ideologue envisages a much wider field of operations—sometimes totaling in the millions. Here entire sections of the population are targeted for destruction: Jews, gypsies, homosexuals, the bourgeoisie, heretics, racial minorities, and many others. The guiding ideologies are by now very familiar to us, but it is easy to miss them when they emerge, because they masquerade as moral crusades. It is often only in retrospect that an evil ideology reveals itself for what it is. Ideological evil allows people to destroy the good while telling themselves they are working for a greater good, so it is especially sinister and dangerous. They make people think that their evil acts are not evil at all. Whenever you see people justifying destructive acts by reference to an ideology be on the lookout for ideological evil. One sees in the ideologue a wild-eyed enthusiasm, a disregard for basic principles of fairness and justice, violent imagery and extreme response, blanket condemnation, sloganeering, demonizing, prejudice and pre-judgment, sectarianism, and social conformity. The psychology of ideology is murky, but the human mind clearly has a weakness for ideology, and the results can be devastating (consult history). I don’t doubt that one of their principal attractions is that they permit people to do evil in the guise of promoting the good.

It is important for any conception of evil to distinguish it from merely bad or immoral acts. Evil acts are always immoral, trivially, but not all immoral acts are evil. It is not ipso factoevil to break promises or steal or tell lies or defraud or assault. In certain circumstances all these can be evil, but they are not evil in all circumstances. So we had better hope that they don’t turn out to be evil according to our definition. Nor do they: breaking a promise or stealing things are not intentional under the description “destroying the good”. They are not even cases of intending to do harm, even if they do in fact do harm. When I break a promise to you I have not identified a good in you that I proceed intentionally to eliminate; I simply act selfishly or lazily. Nor is it my aim in stealing from you to remove a good from your life; it is simply to add a good to mylife. I would be quite happy to enhance my life by leaving yours undisturbed, so long as I get what I want; taking your things is just my means to enhancing my life. It is entirely contingent that my gain is your loss.

By contrast, if I decided to steal from you in orderto deprive you of something precious to you, even if it meant nothing to me, then I would be acting evilly. But ordinary instrumental theft, in which I am merely trying to accumulate more goods for myself, does not exemplify the evil schema; I am not so much destroying a good as transferring it from you to me. Even assaulting another person, say in the course of robbery, is not evil by the criterion laid down here, since this is merely a means for me to get what I want. I am not trying to obliterate a good that you have; I am simply using the means necessary to my obtaining a good that I want. I would be quite happy to get what I want without assaulting you, but as it happens I have to. If I assault you intending to destroy your happiness and future, then I am acting evilly; but not all assault is so motivated. A crime it may be, and it is certainly immoral; but it is not evil, intuitively or according to our theory. It all depends on the motive behind the assault.

This is why, if the assault is disproportionate to the intended theft, it veers into the realm of the evil. If all I need to do is twist your arm, but I hit you on the head with a brick, then I have acted evilly, because I have removed more good from you than if I had used the minimal means to enact the theft. My action is immoral either way, but it is only evil when I destroy a good as an end in itself. Just war and self-defense both involve destroying good things, notably lives, but they are not evil because there is no intention to destroy the good as an end, just as a (proportionate) means. I would even distinguish between verybad acts and the subclass of bad acts I am calling evil acts. It is very bad to steal from helpless old ladies, and more so to assault them, but this is not a case of downright evil, as when you decide to terrorize old ladies for its own sake. It is when you take aim at their wellbeing itself that you become evil. The hardened criminal is not necessarily opposedto the good of others; he is merely out for his own good, irrespective of the deprivations he brings to others.  But Iago is not just a self-centered criminal using Othello for his own enrichment; his intention is rather to destroy Othello, mind and body, without regard for how he might benefit. A career criminal would find Iago irrational, given the risks and potential payoffs, but Iago is quite rational given his real aims. He is in the business of removing the good not in acquiring goods.

The evildoer is therefore often quite difficult to distinguish from the mere criminal or immoralist. The actions look the same from the outside; it is the inner attitude that makes the difference. The same act of violence can be motivated by evil intentions or by merely criminal intentions. It would be easier if all evil actions were purelyevil, i.e. motivated by nothing more than a desire to destroy something good. But some evil is instrumental—the agent expects to get something out of it himself. Here is where evil can shade into mere criminality or wrongdoing. Suppose I have a selfish aim and I am not too particular about how I achieve my aim: then I am not ipso factoevil, just rather unscrupulous. I might cheat people or coerce them or rob them to get what I want. This is not yet to act evilly towards others, because my focus is not destroying what is good for them. It is said by historians that the Germans at the beginning of their persecution of the Jews sought only to have them leave Germany: they made life difficult for Jews in the hope that they would voluntarily leave the country. These were no doubt deplorable and vicious policies, but they do not compare to the policies that succeeded them. If the Jews were not willing to leave voluntarily, then they would have to be exterminated. At first this was achieved by mass executions conducted wherever Jews lived, using bullets, but that was deemed inefficient, so special extermination camps were set up, where starvation and gas were used to kill people. Here the intentions of the Germans were nakedly sadistic and designed to bring about extreme degradation. They wanted to remove as much as possible of what makes life good from the Jews in their captivity. In this they entered the realm of evil quite decisively. They began to make the destruction of soul and body an end in itself. At the beginning they had an instrumental desire to force Jews into exile, but as time went on this was replaced by a desire to annul everything Jewish. They went from the merely criminal and bad to outright evil and depravity. They sought systematically and ruthlessly to destroy the good as exemplified in a population of people.

We find evil shocking in a way we don’t find routine crime shocking. Why? The theory gives us the answer: because the evil will is aimed at the destruction of the good. The criminal will is not: it is aimed rather at the good of the criminal, with indifference towards the good of others. But the evil agent is bent on the destruction of the good as such—in the purest case, he wishes simply to destroy what is good without any benefit accruing to himself. This is shocking, because we normally think that the pursuit of good states of affairs is what human motivation is all about. The evil agent inverts that assumption and aims to annihilate the good, not create it (in himself or others). We wonder why anyone would do anything so negative; hence the evil agent strikes us as a monster, a freak, even a paradox. The merely self-interested criminal, by contrast, is normal in his motivation, just unscrupulous. We wonder what the pointof evil is, if it is aimed solely at the reduction of the amount of good in the world. No one’s utilities are being maximized. This raises the question of motivation, which I don’t want to get into here. Suffice it to say that envy, competition, and Schadenfreude often play a role. There is also, apparently, a brute appetite for destruction for its own sake—a kind of generalized vandalism. It may have to do with assertions of power, and certainly evil shadows power. In any case it is the opposite of the normal desire to bring about the good.[3]

Let me end with the question of natural evil, i.e. the kind that arises in the world independently of anyone’s will—earthquakes, floods, fires, disease, etc. This appears to be a counterexample to the theory defended here, since the natural destruction of the good is not an intentionaldestruction. Of course, if there is an agency behind it (say, Satan), then it fits our definition—these events are instances of intentional action. But suppose they are purely natural—what should we say about this kind of evil? My answer is that this is not a kind of evil; it is simply the occurrence of bad states of affairs. Talk of evil here is just a holdover from antiquated ways of thinking about the natural world, as if everything that happens must be willed by somebody. There are evil agents, but there aren’t evil facts or events or conditions. So the notion of “natural evil” is an oxymoron, unless we explicitly postulate an agent behind the bad events. A child dying of cancer is no doubt a horrible thing, but it is not an evil thing. What is called “the problem of evil” only arises when we introduce an agent like God. The problem is usually posed by asking why God allows horrible things to happen, as if he is a passive bystander too lazy or indifferent to lift a finger; and indeed, that is a form of evil (“passive onlooker evil”). Then evil is involved, but only because of an assumed agent—not because of the horrible event in itself.

But there is also the problem of active divine evil if we suppose that God is responsible for everything that happens—if he is the cause of all natural events. Then it looks as if God is actively, intentionally, and knowingly producing very bad states of affairs—that is, he is destroying the good on a grand scale. He then appears as an evil agent. This problem of evil (“active agent evil”) is even worse than the kind in which God is conceived as a mere onlooker, since it is his will that actively creates the bad state of affairs. How can God be good and yet he intentionally produces very bad states of affairs? The only conceivable answer relies on the model of the benevolent dentist, but that rings very hollow to most people. In any case, there is no counterexample here to the definition, since God wouldbe evil if he intentionally destroys the good (without some excusing instrumental explanation). In either case (God or no God) the existence of “natural evil” poses no problem for our theory.

I hope that the theory I have presented strikes the reader as natural and intuitive, almost a truism. Truism or not, it still serves to bring order to our thinking about evil, by providing an account that discerns uniformity in the many varieties of evil. We don’t have to fall back on a disjunctive analysis or a vague family resemblance story, i.e. no definition at all. We now know what to look for when we are keeping our eye open for evil. Thus a theoretical advance might lead to a practical advance: we might become better at detecting evil, and hence preventing it. It is also good to reserve a special label for one particular kind of human badness, and we need to be able to justify the use of the concept of evil in our classifications of human actions. We need to know that the word “evil” denotes a coherent and well-defined natural kind—a distinctive moral natural kind. My view is that the concept of evil is a vital part of our moral conceptual scheme, corresponding to a very real type of human act. My aim has been to buttress the concept by providing a clear and straightforward definition of it, applicable to the major kinds of evil that exist. Absolute precision may not be possible, and borderline cases can no doubt be constructed, but I hope to have shown that the concept of evil deserves a place in our repertoire of moral concepts. Actually getting rid of evil may not be so easy.

Philosophy as Biology

 

 

In the 1960s linguistics took a biological turn with the work of Lenneberg and Chomsky.[1]Language was held to be genetically fixed, a species universal, just like the anatomy of the body. It is a biological aspect of human beings, not something cultural or learned, more like digestion than chess. Language evolved, became encoded in the genes, and is present in the brain at birth. Since linguistics is properly viewed as a branch of psychology, according to these theorists, this means that part of psychology is also biological, not something separate from and additional to biology. But then it is reasonable to ask whether more of psychology might fall under biological categories; and succeeding years saw psychology as a whole taking a biological turn. Many of our mental faculties turn out to have biological origins and forms of realization in the organism. Indeed, learning itself must be genetically based and qualifies as a biological phenomenon: what an animal learns is part of its biological nature, not something set apart from biology. True, what is learned is not innate, but many things are not innate that are part of the natural life of the organism (e.g. a bee’s knowledge of the whereabouts of nectar). Dying by predation is not innate but it is certainly biological. Biology is the science of living things, and living things learn as part of their natural way of life. In any case, psychology turned from cultural conditioning to biological naturalism; it became evolutionary. How could it not given that minds evolved along with bodies? The mind of an organism is part of its nature as a living thing; it doesn’t exist outside the sphere of biology (as the soul was supposed to). The organism is a psychophysical package.

The basic architecture of language is thus a biological architecture. Syntax is an organic structure; the lexicon is a biological system too. When we study these things we are studying the properties of an organism, just like its other biological properties. They had an evolutionary origin in mutation and natural selection, and they have a biological function (probably to enhance thought, as well as serve in communication). One of the organs of the body, the brain, serves as the organic basis for language, as the heart serves as the basis for blood circulation. So linguistics (descriptive grammar) is not discontinuous with biology but part of biology.[2]It had conceived itself differently, perhaps out of a feeling that language raises us above the level of the beasts, but in these post-Darwinian times it should be relegated to biological science. Freud had made similar moves in affective psychology; the biological school in linguistics was moving in the same general direction. This broke down the old dualism and established the study of language as a department of biology, even when it came to the fine structure of grammar.

This is an oft-told tale (though still not without its detractors), but it has not yet colonized the entire intellectual landscape. Recently there has been a movement to classify consciousness as a biological phenomenon: it too is innately determined and biologically functional. Organisms have consciousness the way they have blood and bile—as a result of biological evolution and bodily mechanisms. It is not something supernatural, an immaterial infusion. That certainly seems of a piece with the biological naturalism that has dominated psychology in recent decades, but does it go far enough? Can’t we also announce that phenomenology is a branch of biology? That is, the systematic phenomenology of Husserl is really a form of biology: the very structures of consciousness are biological facts. Husserl doesn’t suspend the natural sciences (the epoche); he promotes one of them. Phenomenology is the study of a biological aspect of the human mind (and bats have their phenomenology too), just as linguistics is the study of a biological aspect of the human mind (and bees have their language too). When Sartre characterizes consciousness as nothingness and explores its modalities he is doing biology, because consciousness is a biological phenomenon—evolved, innately programmed, functional, and rooted in tissues of the body. To be sure, it is not reducible to otherbiological facts (such as brain structures); it is a biological fact in its own right. But it is a biological fact nevertheless—part of the life of a living thing. Its essence is nothingness, as the essence of the heart is pumping and the essence of the kidneys is filtering. It has a certain natural architecture, established by the genes, in both humans and animals. We certainly don’t chooseits essence. In so far as consciousness exhibits universals (intentionality, qualia, transparency), those are biological universals, like the universals of human grammar. Phenomenology thus belongs with psychology as a branch of biology. Biology deals with living things–as opposed to physics, which deals with non-living things—and the mind is an aspect of life. Husserl could have cited Darwin (correctly understood): The Origin of Species of Consciousness. This is not biological reductionism, simply the acknowledgment that biology extends beyond the body. It is not that religion takes up where biology leaves off.

I take it I am not shocking the reader unduly. Isn’t this all part of our current secular scientific worldview? Biology by definition encompasses the life sciences, and linguistics, psychology, and phenomenology are all parts of the life sciences. Speaking, thinking, and experiencing are all modes of living—what living things do (some of them). They are, as Wittgenstein would say, aspects of our “form of life”, part of our “natural history”. Maybe we need to expand our conception of biology beyond the typical curriculum, but it is not difficult to see that these aspects of our nature properly belong to biology, broadly conceived (certainly not to the physical sciences). However, I now wish to assert something that may strike readers as pushing it just a bit too far: philosophy too is a branch of biology. I don’t say this because I think philosophical questions reduce to biological questions; I say it because of the methodology of philosophy. We hear about the “linguistic turn” in philosophy—using the study of language as a means of arriving at philosophical conclusions about ground-floor questions. But given the biological turn in linguistics this implies that philosophy has already turned into a branch of biology. Language is a biological phenomenon and it is held to be the foundation of philosophy, sophilosophy is based on a sub-discipline of biology. If the logical form of sentences is deemed central to philosophy, then it is the form of a biological entity that is in question. Logical form, like syntax, is an aspect of an evolved and biologically based entity—the architecture of a biological trait of humans. If speech acts are deemed central, then this aspect of living things will assume methodological importance—as opposed to acts of reproduction or respiration or excretion. The combinatorial power of language has rightly received considerable attention, but this too is an evolved biological trait. The biological turn in linguistics combined with the linguistic turn in philosophy together imply the biological turn in philosophy.

But what if we reject the linguistic turn? What was it a turn from? Mainly it was a turn from a more direct investigation of concepts. But investigating concepts is also investigating a biological phenomenon. Let me put it bluntly: a concept is a living thing. A concept is like a cell of the mind (and note that biological cells were so called because of their resemblance to the living quarters occupied by monks). Concepts are the units that make up thoughts and other mental states, as words make up sentences. Concepts have functions, they evolved, and they are rooted in organic structures of the brain. So when we study concepts philosophically we are studying entities as biological as blood cells or enzymes. We scrutinize these things for their philosophical yield, not for their contributions to biology as such, but they are still biological entities. To be sure, we are interested in their content not their physiology, but having content is just another biologically fixed fact about them. Even if you think concepts are acquired by abstraction, they are still entities that exist in the context of a living organism (like big muscles or manicured nails). Conceptual analysis is the dissection of a biological entity; it is not the examination of a disembodied abstract form. There might be such forms, but they must be reflected in the natural traits of organisms at some level. We have no trouble recognizing that an animal’s concepts are biological forms; human concepts are not different in kind. Bee philosophers can reflect on their bee concepts (or turn their attention to bee language), and human philosophers are in the same case—reflecting on their biologically given traits.[3]How they do that must also be rooted in biology, but the important point is that thinkingis a biological fact; and in so far as philosophy concerns itself with “the structure of thought” it is a biological enterprise. The results don’t concernbiological matters, as opposed to matters in the world at large, but the methodinvolves surveying a certain class of biological entities. Analyzing a concept is analyzing a living thing—as much a living thing as any organ of the body. Our intellectual faculties are indisputably aspects of our life as organic beings, and concepts are just their basic components—as cells are the basic components of bodily organs. It follows that philosophy is (a branch of) biology. Philosophy could be called conceptual biology.

I want to emphasize how biological concepts are. First, they arise through the evolutionary process (though we have little understanding of how this happened). Second, they are manufactured during embryonic development as a result of genetic realization (or if you think they are acquired later, it is by biological means, e.g. abstraction). Third, they have a biological function—to enable thought, which enables rational action. Fourth and crucially, they must be realized in some neural mechanism that enables them to have their characteristic features, chief among which is their combinatorial powers. The neurons must be able to hook up with other neurons so as to produce complex thoughts; and this hooking up must respect the logical relations inherent in thought (it’s not just a matter of brute aggregation). There must be a physiology of thinking, and specific to thinking. So concepts cannot somehow float above the biological substructure; they depend upon it. Presumably this implies some sort of hidden structure to concepts analogous to the hidden structure of the cell (nucleus, mitochondria, etc.) Concepts are biological through and through. So if they are what philosophy investigates philosophy is up to its ears in biology. It would be different if philosophy could pursue its interests without recourse to concepts, say by simply looking at the extra-conceptual world, but that idea is hopelessly wide of the mark. And even if you think that someparts of philosophy require no reference to concepts, much of it clearly does (the parts that expressly analyze concepts, in particular). Philosophy is thus one of the life sciences and should be understood as such. There are the sciences of the inorganic world—physics, chemistry, astronomy, geology—and there are the sciences of the organic world—zoology, biology, genetics, biochemistry: and within this broad grouping linguistics, psychology, phenomenology, andphilosophy fall into the latter category. As I say, this is no form of biological reductionism or determinism, simply a taxonomic observation. It is making explicit what has been implicit since the time of Darwin.[4]

I want to end with a point about mathematics. The kinship between mathematics and philosophy has long been recognized; in particular, the status of mathematics as a non-empirical conceptual inquiry makes it similar to philosophy. So is mathematics also a department of biology? Well, if we view it as investigating the implications of basic mathematical concepts it presumably is, for the same reasons philosophy is. Mathematical concepts are products of evolution too, and they must have an underlying physiology. They too are living things. To the extent that mathematical concepts are part of the subject matter or method of mathematics, that subject is also fundamentally biological. Suppose mathematical ideas are innate, just as the classical rationalists supposed; then they must have evolved by mutation and natural selection, become genetically encoded, and matured in the individual organism’s brain to become the conscious entities we now know. Investigating these concepts is thus an exercise in biological exploration—discovering what these evolved traits have hidden in them. How they evolved we don’t know, but if they did evolve then mathematics is another kind of life science, mathematics being part of human life. The concept of number, say, is part of our evolved form of life (quite literally). Counting is like speaking—a human universal. Mathematical theory is the spelling out of the mathematical concepts we inherited from out ancestors.

[2]The work of Ruth Millikan is also an instance of the biological turn in linguistics and psychology, to be set beside Lenneberg and Chomsky. The biological concept she emphasizes is function as distinct from innateness.

[3]No one would doubt that the study of bee language belongs to biology (zoology to be precise), but it took some persuasion to get people to accept that human language is part of human biology (zoology). If bees had philosophers it would be clear enough that these philosophers are studying a biological phenomenon—bee language or bee thought. Is it that there is resistance to the very idea of human biology?

[4]In retrospect we can see the work of Locke and Hume (among others) as a form of human biology: they undertook a naturalistic study of the human mind, turning away from scholastic essences and the like. If they had known about Darwin, they might have welcomed the biological naturalism inherent in his work.

Psychological Science?

 

Is Psychology a Science?

 

 

The question is only as precise as the word “science”, which isn’t very precise. But I don’t propose to quibble about that word (I incline to a wide application of it); instead I will compare psychology to some established sciences and note various gaps in what psychology has accomplished compared to these sciences. We might express the upshot of these reflections as denying that psychology is a maturescience, or that it is a realscience, or that it is an explanatoryscience; what matters is the reality of the distinctions I identify. Psychology is not as other sciences are, dramatically so. It is signally lacking in the chief characteristics of the sciences, as they now exists. It is weak science, proto science, science in name but not in substance.

First consider the physical sciences—physics (pure and applied), cosmology, astronomy, and chemistry. What has physical science achieved? I would say that it has achieved success in three (interconnected) areas: origin, structure, and dynamics. To summarize: it explains the origin of the physical universe (big bang cosmology); it has uncovered the hidden composition of physical things (atoms, molecules, fields); and it has developed a dynamic theory of how the physical world evolves over time (specifying the basic forces and the laws that govern them). I shall say that it has achieved OSD success: it has established theories of how matter came to exist in its present form, how it is composed, and how it changes its properties with time. This is what we would expect of an adequate empirical scientific theory of some aspect of reality: an account of its origins, its underlying structure, and its behavior over time. Not to have answered these questions would make physics into a merely embryonic science, hardly worthy of the name (think physics in the age of Aristotle or earlier). Now turn to biology—anatomy, physiology, evolution, and genetics. It too can boast real achievements in the three areas identified: how life originated, the structure of living things, change of biological forms over time. We now know that life on earth began with bacteria some four billion years ago (though we don’t have a clear idea of how bacteria came to exist), and it has been evolving by means of mutation and natural selection ever since. We also know about the fine cellular structure of organisms, as well as the molecular structure of the genetic material. And we have a well-established theory of how organisms change over time (the aforementioned evolution by natural selection), as well as how individual organisms function biologically (blood flow, enzymes, digestion, photosynthesis, etc.) Granted, we don’t know everything about life–as we don’t know what preceded the big bang or how to integrate quantum physics and gravity—but we have made serious progress in understanding these three aspects of the biological world. Biology is well advanced in OSD studies. It is not that a student of the subject would have fundamental questions in these three areas about which biology has established nothing. What we expect of a reputable science is that it can tell us where its proprietary entities came from, how they are internally structured down to the microscopic level, and what explains change in them over time. Biology and physics satisfy these criteria.

But what about psychology–can itboast comparable achievements? The short answer is no. What theory in psychology plays the role of big bang cosmology in physics and Darwinian evolution in biology? None: psychology has no theory of how minds as they currently exist came to be. The best it can do is piggyback on biology, but there is no explanatory theory of how minds with their characteristic properties came to be—subjectivity, consciousness, intentionality, reason, introspection, and more. How did these develop from more primitive traits? How did the whole process begin? If a mind is like a galaxy, how did the mental galaxy form? Psychology just accepts minds as they are, animal and human, but it doesn’t explain how they came to be, what triggered them, what shaped them. There is no origin story in psychology. What about structure? We can say what the partsof the mind are—the analogues of bodily organs—but we have nothing to say about the ultimate constituents of the mind, especially its hidden structure. People mumble about “bits” of information, as if these were the atoms of mentation, but really this is hand waving, not solid science. There are no microscopes of the mind, no diffraction chambers, no spectral analyses, no supercolliders. Psychology makes do with commonsense divisions into belief and desire, memory and perception, emotions and sensations; but there is no elaborated theory of fundamental constituents analogous to atoms and molecules, cells and DNA. We don’t know how our mental life is built up. And what about dynamics? How does psychology explain the flow of conscious thoughts or the changing behavior of the organism? What laws are cited to predict how one thought will follow another, or how emotions influence overall mental state, or how a subject will act in a novel situation? Psychologists like to talk about various “effects” (e.g. the Zeigarnik effect), but where is the analogue to Newton’s three laws of motion? We just don’t have a theory of how a psychological system changes over time; at best we have rough hints about what might lead to what (as in “laws of association”). Where is the unified theory of psychological dynamics? Where are the equations of thought and action? A physicist or biologist encountering psychology for the first time might wonder how the subject accounts for origin, structure, and dynamic change—the basic facts she is familiar with in her own discipline—but her psychology professor will have little to say about these questions. He will report some experiments, maybe some established “effects”, but he won’t have comprehensive theories to offer in these three areas. He won’tsay, “I’m glad you asked that question because we have great theories of how minds originated, what composes them, and how they change with time”. If he is honest, he will mutter in a low voice, “Good question, we’re working in it”, perhaps followed by some boilerplate about psychology being a young science and all that (but is it really any younger than physics and biology?).

Compare linguistics. Chomsky has long pointed out areas of ignorance in that field, mainly relating to the evolutionary origins of language and in the free use of language in speech (“performance”). The evolution of language is largely a mystery, especially the origins of the lexicon, and the stimulus-freedom of speech makes language use hard to subsume under predictive laws. Some progress has been made with linguistic structure, but even here it is reasonable to wonder whether we have reached linguistic bedrock. So linguistics has not achieved what the established sciences have. Linguistics is really a branch of psychology, and it looks as if psychology in general has the limitations Chomsky finds in this branch of it. There is some grasp of structure, basically extrapolated from commonsense psychology (including commonsense linguistics), though it has nothing like the depth we find in physics and biology. But the origins of the language faculty in evolutionary history, and how that faculty is manifested in action, are shrouded in mystery. Whether the mystery is temporary or permanent, contingent or necessary, is another question; what is clear is that psychology and linguistics do not have the kinds of explanatory success found in the established sciences. And what holds for linguistics and psychology also holds for sociology and anthropology (and maybe economics): how social structures and cultures came about is unexplained except in the most rudimentary terms, and there is no generally accepted dynamic theory of how they change over time (Hegel and Marx anyone?). Human history is not like the history of the physical universe or of the biological world. Freud made some heroic efforts to do for psychology and human history what physics and biology have achieved in their domains, but his efforts are not generally lauded. The simple fact is that the psychological “sciences” are nowhere near as advanced as the physical and biological sciences. They suffer from OSD deficiency. This is not, of course, the fault of psychologists, who are just too lazy or incompetent to bring the subject to maturity; it is inherent in the subject itself. It is very difficultto explain how minds originated, what their compositional structure is, and how they change over time.[1]I intend no aspersions on the field or its practitioners; I merely point out certain significant asymmetries. Presumably the mind hassome sort of intelligible origin (it didn’t just spring into existence from nothing), and some sort of internal structure (the “cells of thought”), and some dynamic principles (not just stochastic chaos): but we are far from understanding what any of these might be. Nor do I see any relief on the horizon. It is pretty amazing that we have achieved the kind of insight in physics and biology that we have, and it didn’t happen overnight; there is really no guarantee that psychology will ever repeat these successes. Psychology might always remain a semi-science.[2]

 

[1]Note the contrast with the brain as an organ of the body. There is no more difficulty explaining its origin than other organs of the body; it is composed of cells that are composed of molecules; and its dynamic mode of operation is the nerve impulse that changes the brain’s state over time. We havea science of the brain, much as we have a science of matter and life, though of course it still has a long way to go. But that doesn’t provide us with the right level of explanation to account for the mind. Perhaps this is (partly) why people tend to favor neural reductionism: it enables psychology to mirror the theoretical successes of the other sciences.

[2]That is not to say that it can’t be useful or illuminating, just that it may never mimic the OSD successes of physics and biology.

Conceptual Skepticism

 

 

 

Skepticism About the Conceptual World

 

 

I will describe a startling new form of skepticism, to be set beside more familiar forms. It lurks beneath the surface of recent work on meaning and reference. Consider “water”: it has both a meaning (sense, connotation) and a reference (denotation, extension). Suppose its meaning is equivalent to “tasteless transparent liquid found in lakes and flowing from taps”. These are the properties a typical speaker associates with the word (its “stereotype”). Combining these words with “water” produces an analytic a priori truth. They provide an analysis of the concept we associate with “water”. Yet they are not epistemically necessary: it could turn out that water is none of these things, as it could turn out that water is not H2O. Perhaps we have all been under a giant illusion about these properties of water: by some quirk of our nervous system a yellowish lemony-tasting liquid has appeared to be transparent and tasteless, and what fills lakes and flows from taps is some other liquid than water. These possibilities are not beyond the powers of an evil demon to contrive. We cannot be certainthat water has the properties we typically associate with it—mistakes are possible, illusions conceivable. Water might turn out to have none of the properties included in its stereotype, i.e. its meaning or connotation. Yet we would still be referring to water by “water”, whatever water is. The reason this is possible is that we fix the reference of “water” in a certain way, namely by pointing to a sample of a certain natural kind and saying, “Let ‘water’ designate whatever natural kind underlies these appearances”—whether those appearances are veridical or not. We might thus have successfully referred to a certain liquid and yet acquired quite false beliefs about its properties. Reference is independent of opinion: appearances can be inaccurate even as reference succeeds. If we adopt a causal theory of reference, we can say that the reference-establishing causal relations are logically independent of whatever beliefs we form about the extension of the term. What this means is that the sentence “Water is a tasteless transparent liquid found in lakes and flowing from taps” is both analytic and conceivably false. It could be false because water might actually have none of these properties and yet the meaning we assign to the term includes them: they are contained in the connotation but the denotation lacks them. Thus we have an analytic but false statement—it makes a false ascription of properties to thing we refer to.

Now consider skepticism. Hearing about the semantics of natural kind terms the skeptic will seize his chance: he will insist that all our natural kind terms are vulnerable to a skeptical doubt, namely that propositions formed from them are not knowable with certainty, even when analytic. We might be wrong that water is tasteless and transparent, that lightning is bright and precedes thunder, or that gold is shiny and malleable. These are characteristic skeptical claims, but the extra turn of the screw is that analytic truth does nothing to preserve them from skepticism. The semantics of the terms combines demonstrative reference with fallible descriptive stereotype, so that the reference could succeed while the stereotype is inaccurate. Sense (descriptive content) doesn’t determine reference, but it can generate analytic truths nonetheless. Since the descriptive content of sense is possibly erroneous, we can generate fallibly known analytic truths—we can’t be certain that these are truths. Water might turn out not to be what we suppose, however much what we suppose fixes its meaning (one aspect of it at least). In the extreme, water might be a bitter tasting dark-colored solid that has presented a totally misleading appearance to us all these years—so the skeptic will contend, and he is notoriously difficult to thwart. What we have been designating by the term is quite different from the way it appears (if one day the scales fell from our eyes, we would exclaim “So that’s what we’ve been drinking all this time!” while beholding a mud-like substance).

How far can the skeptic push it? Consider knowledge (the word, the concept, and the thing): we customarily suppose that the meaning of “know” includes belief, truth, and justification—that is its sense or connotation. It also refers to a specific mental state of a person. We take it that this reference instantiates the properties contained in the meaning of the term—that itinvolves belief, truth, and justification. That’s what wemean and itinstantiates. But the skeptic wants to know what makes us so sure that the thing we refer to has the properties we ascribe to it: why assume that the nature of the mental state that “know” refers to actually includes the properties we ascribe to it? Why couldn’t it be like the case of water? Suppose we are confronted by a sample of a certain mental kind and we announce, “Let ‘know’ refer to the mental state before us”, while believing that the state in question is an instance of true justified belief—maybe that’s just the way the sample happens to strike us. But suppose that, contrary to our impression, none of this is true: the state in question is unjustified belief in a falsehood, or not even belief at all but disbelief (the sample is being insincere in its assertions). Then the skeptic maintains by citing the semantics of natural kind terms we can say that knowledge is nottrue justified belief—the state we are referring to is unjustified false belief! Now the question is what we can say to rule this possibility out in our case: might it not turn out that knowledge is not true justified belief at all but false unjustified belief? This is epistemically possible, the skeptic contends, given the way the term “know” was introduced and given the facts of the case. So we should admit that it might turn out that knowledge is not true justified belief, because the term designates something quite different from what we supposed—we had false beliefs about the extension of the term as it actually was at the moment of reference-fixing. But that implies that the analytic truth “Knowledge is true justified belief” might turn out to be false, simply because the state originally designated lacked the properties we thought it had. Our false ideas entered its meaning, but reality failed to confirm these ideas. The proposition might be analytic but false, and the skeptic wants to know what we can say to rule out this possibility. Of course, it is also epistemically possible that knowledge istrue justified belief, but the skeptic is asking why we prefer that alternative to his skeptical possibility. We should be agnostic.

Or consider “bachelor” and suppose that the initial sample is quite other than what the introducers of the term think: they think they are confronted with a bunch of unmarried males but in fact they are confronted by a group of married females. These individuals are masquerading as unmarried males while being just the opposite. The fooled introducers then stipulate, “Let the word ‘bachelor’ designate the marital and gender status of thisgroup”. They fix reference to the property of being married and female while mistakenly believing that the group in question is male and unmarried. Then the sentence “Bachelors are unmarried males” is false for these speakers, despite their firm belief in its truth. It may indeed be analytic in their language, but it is still false. And now the skeptic asks how we can rule this out in our own case: couldn’t it turn out that bachelors are married females? Maybe our ancestors introduced the term in the way described and thereby fixed its reference to married females; their beliefs were false of these individuals, but so what? Thus we today refer with “bachelor” to the natural kind of married females, even though we thinkwe refer to married males. Or suppose all the people we have ever met who called themselves “bachelor” and gave every appearance of being male and unmarried were really married women in disguise—wouldn’t that tie down the reference to that group, not the group we thoughtwe were referring to? If this is the way reference works in general, then such skepticism would seem indicated. It might turn out that bachelors are married females! It is not epistemically necessary that bachelors are unmarried males, despite the analyticity of the corresponding sentence. The skeptic thus extends his doubts to knowledge of analytic truths.

Let us make explicit what is going on in this argument. On the one hand, we have the concept, an item in the mind; it contains various components, which fix the set of analytic truths with respect to that concept. On the other hand, we have the extension of the concept, an item in the world; it has a certain objective nature, which fixes its de reessence. We normally suppose there is a correspondence between these two levels: the components of the concept actually capture the objective nature of the thing designated. In the water case it is easy to see how this correspondence could be disrupted, because we can be wrong about the properties of the natural kinds we are referring to. The skeptic then seeks to extend this point to other concepts by adopting the same type of analysis: there is the concept we have of knowledge, and there is the fact of knowledge itself; but the former might not correspond to the latter—knowledge itselfmight not have the properties the concept ascribes to it. What guarantees that the objective thing has the properties we think it has? It might be like the case of water. Similarly, the concept we have of a triangle implies that triangles have three sides, but the skeptic conjures a scenario in which we introduce the term “triangle” in reference to things that are actually four-sided, thereby referring to such things with the word “triangle”. Then “Triangles are three-sided” would be analytic for us, given our beliefs, but actually false. And the skeptical question is how to demonstrate that our present use of “triangle” is not like this: maybe we actually refer to four-sided figures with the term “triangle”! Might we not one day discover that triangles have four sides, contrary to what we now believe? We might discover that we are brains in vats, and we might discover that we refer to quadrangles with “triangle”. That would be strange, to be sure, but not logically impossible.

How could we respond to the skeptic? Gap closing is the obvious manoeuver: don’t let the concept and the property diverge. Then there will no logical space between what we think and what is. Thus we might identify the property with the concept: forxto have Pis just for xto have C(correctly) ascribed to it. But this gives rise to an idealism that destroys objectivity—as is typically the case with this kind of counter to skepticism. Clearly there was water before there was the concept of water, and similarly for knowledge, triangles, and bachelors. At the other extreme we could try going radically externalist and make the concept nothing more than the property: then what is in the mind will not be separate from what is in the object. The trouble is that this will entail that we can’t be misled about the nature of water, or mistaken about what knowledge involves, because our concept will simply bewhatever these things are objectively. A more realistic suggestion is that there is a kind of pre-established harmony between the concept and the property: the constituents of the concept necessarily correspond to the constituents of the fact (the nature of the property). But again, this fails to allow both for error and for incompleteness: our concept may misrepresent the property and it may fail to exhaust its nature. For example, there may be more to knowledge than we think, and our conception of knowledge may be inaccurate in some respects. This is precisely what the skeptic is capitalizing on by pointing out the epistemic possibilities: water may not be as we suppose it to be, no matter how central to our concept a certain feature is; and similarly for other natural kinds. His point is that analytic containment in the concept is no proof against the possibility of such errors about reality. The world contains various phenomena and we are trying to capture them in our concepts, but we may fail; so it might always turn out that things are not as we take them to be. Water might not be transparent, knowledge might not be true, triangles might not have three sides. Of course, ifthese things have those properties, then it is plausible that they have them necessarily; but the question is whether we know with certainty that they do, and the skeptic finds reason to doubt this. Metaphysical necessity does not imply epistemic necessity.

It might be said that the underlying semantics presupposed by the skeptic applies to semantically simple expressions like proper names and natural kind terms but that not all terms fit this mold. The former terms denote by mechanisms independent of their descriptive content, which forms a separate component of meaning; but terms like “knowledge” and “triangle” and “bachelor” don’t work like that—here the descriptive content is active in fixing reference. Thus the meaning of “know” mustimply truth in knowledge itself because that is simply how the term determines its reference—“know” refers by definition to what is believed and true (etc.). It is semantically complex and works as a logical conjunction of conditions, unlike a proper name. This, however, is all very debatable and anyway faces an obvious retort: what about the simple elements that make up the meaning of the term? Thesewill be subject to the same skeptical argument that we started with: maybe “believe” and “true” denote properties other than we suppose because they were introduced under conditions of fallibility. We announce “Let ‘believe’ denote thatmental state” in front of a sample, convinced that we are referring to a state of internal assent, but in fact our sample is in a state of suspended assent or outright dissent. We don’t have infallible access to other minds! Same for triangles (so we can’t wriggle out of the problem by appealing to introspective authority): we supposethere are three-sided figures in front of us and we stipulate that “triangle” refers to thatgeometrical form, pointing at the sample; but in fact we are suffering from a visual illusion and four-sided figures constitute the sample. The skeptic is saying that we can always misrepresent the properties of the sample that forms our semantic anchor, which is why it may turn out that we have actually done so. Analytic containment in the concept is no protection against this possibility. Skepticism about the external world thus generalizes to skepticism about what we regard as definitional. That is to say, we can be wrong about the essence of things as well as about their accidental properties, even when that essence is supposedly contained in our concepts. Since complex concepts resolve into simpler ones, the skeptical problem can always recur at the basic level.

This skeptical problem deserves to be called a skeptical paradox because whether or not I know anything I surely know what it wouldbe to have knowledge—I surely know that I cannot know what I disbelieve or what is false! Similarly, I may not know whether there are any triangles in nature but I surely know what a triangle is—I know it’s not a circle! But the skeptic is denying, startlingly, that I do have such knowledge; his claim is that it is epistemically possible that knowledge is not of truths and doesn’t require belief. We just don’t have that degree of apodictic insight into the nature of the things in question; we merely conjecture that this is the nature of what we refer to. We may be profoundly ignorant of the objective nature of the kinds of which we speak. Philosophers took it for granted that knowledge of analytic truths is free from skeptical doubt, but it turns out that they are swallowed up too. How far can this skepticism go? What about our knowledge of what “red” means, or “plus” or “and” or “ought”: can we conceive of scenarios in which people are radically mistaken about what these terms designate? Could it turn out that genocide falls into the extension of “good”? Could “red” turn out to designate blue? Could “and” mean disjunction? These would be paradoxical results indeed, so any skepticism that implied such things would deserve that label.[1]

The skepticism I have been expounding doesn’t apply to our knowledge of our concepts as such: we canknow with certainty what our concepts contain. We know with certainty that our conceptof water includes being transparent and tasteless, and similarly for our concept of knowledge in relation to truth. The skeptic questions the move from this to our putative knowledge of the referenceof our concepts—whether we know that water itself is transparent and tasteless, or that knowledge itself involves truth. What holds of the concept is not the same as what holds of the object it refers to. Thus I can be certain of analytic truths in so far as they concern what is true of my concepts, but I can’t (with certainty) infer from this anything about the essence of what I am referring to with these concepts. Hence (according to the skeptic) water might turn out not to be transparent and knowledge might turn out not to be true and triangles might turn out not to have three sides.[2]

[1]Note that the skepticism I am considering does not contend that there is no fact of the matter about what words mean, only that we cannot knowsuch facts. We could be radically mistaken about what words actually do mean.

[2]I have said nothing here about skepticism concerning rule following, as expounded in Saul Kripke’s Wittgenstein on Rules and Private Language(1982), but that is certainly a useful comparison point for the skepticism presented here (they are not at all the same thing).

Epistemology as Metaphysics

 

 

 

Epistemology as Metaphysics

 

 

We usually teach epistemology as a separate field from metaphysics. On the one hand, there is reality, the subject matter of metaphysics, and on the other there is knowledge of reality, the subject matter of epistemology. It is sometimes said that Descartes made epistemology the foundation of philosophy, ahead of metaphysics, which would only be possible if epistemology were not a speciesof metaphysics.[1]But how could it be, given that the world is separate from our knowledge of the world? The thing known is not the same as the knowing of it. However, this way of carving up the terrain ignores an obvious point, namely that knowledge is also something inthe world—part of reality. If the world is the totality of facts, then knowledge is part of the world, because there are facts about knowledge. Given that facts are the instantiation of properties by objects, we can say that knowledge is the instantiation of an epistemic property by a subject. Each of us instantiates many such properties, because we know many things. There are epistemic facts alongside other types of fact. Compare the philosophy of mind: this is not something separate from metaphysics but a branch of it; it is not somehow opposedto metaphysics. Philosophy of mind (as distinct from scientific psychology) is precisely the metaphysics of mind, and is often so described. Well, epistemology is the metaphysics of knowledge (as distinct from cognitive psychology)—the study of one type of property or fact. If we equate metaphysics with ontology (the “study of being”), then epistemology is a branch of ontology, simply because it investigates a region of being—the epistemic region. Thus metaphysics subsumes epistemology.

It is the same with ethics. Ethics is not independent of metaphysics but a department of metaphysics (I am talking about so-called meta-ethics). Moral philosophy is just the metaphysics of morals (as Kant entitled his famous book). It seeks to answer general questions about the status of moral value—whether it is subjective or objective, relative or absolute, a matter of emotion of cognition, etc. Similarly, epistemology concerns itself with such general questions about knowledge: whether we have any, what types of knowledge there are, whether knowledge is the same as true belief, what the nature of justification is, etc. We might helpfully divide the philosophical study of knowledge into three areas to be labeled “practical epistemics”, “normative epistemics” (or “epistemic theory”), and “meta-epistemics”. Practical epistemics deals with specific questions such as whether the belief in God can be justified, or whether we have good reasons to accept Darwinian theory, or whether we really know that global warming is real. These are analogous to the ground floor questions dealt with in practical ethics (abortion, animal rights, capital punishment, etc.). Normative epistemics deals with the general nature of justification (an epistemic norm): is it a matter of consequences, as with pragmatism, or is it constituted by conformity to rules of inference such as induction, deduction, and abduction? This is analogous to normative ethics, which deals with the general notion of right action (giving us consequentialism and deontology). Then there is meta-epistemics, which addresses itself to the analysis of knowledge, the possibility of knowledge (skepticism, epistemic limitation), the objectivity of justification, etc. Just as not all of moral philosophy is rightly described as metaphysics, though some certainly is, so epistemic philosophy is not all metaphysical in nature, though some certainly is. The standard questions of a university course on epistemology are in effect metaphysical questions about knowledge. For example, asking after the general nature of knowledge (the “analysis of knowledge”) is a metaphysical (ontological) inquiry—it wants to know the nature of a certain type of fact. Is knowledge reducible to true belief? Is knowledge constituted by a certain sort of causal connection to the world? Is justification a matter of coherence or indubitable foundations? These are all questions about a certain sort of property, not different in kind from questions about belief or meaning or sensation. We might even say that epistemology is one branch of the philosophy of mind, being concerned with certain attributes of mind (epistemic attributes); and we already know that philosophy of mind is a branch of metaphysics.

Viewing the geography this way is not, as they say, purely semantic, a matter of mere labeling. For including epistemology in metaphysics opens up ways of thinking that might prove helpful in epistemology. For instance, the analysis of knowledge has been confined to specifying conceptual constituents for the concept of knowledge, as with the classic analysis into truth, belief, and justification. But applying apparatus developed in the metaphysics of mind yields other options: what about the idea that the property of knowledge is a simple primitive property that is nevertheless supervenient on truth, belief, and justification (or whatever else needs to be added)? That is, we adopt a non-reductive but dependent view of the property of knowledge. We thus take the concept of knowledge to be non-derivative yet not divorced from other facts about the knowing subject. Knowledge would then resemble goodness as Moore conceived it, or as some metaphysicians view color: dependent but conceptually irreducible.  Also, we could treat the topic of epistemic norms as part of a general metaphysical issue concerning norms in nature, as with moral norms and linguistic norms. What we ought to believe is one kind of “fact” that needs to be located in a world of purely natural facts; or it is held not to be a kind of factat all—depending on your metaphysical views. Naturalizing epistemology is thus like naturalizing ethics or semantics. We can’t really consider the question with respect to epistemology without taking on the broader metaphysical question, construed as such (Quine should have called his much-cited paper “Metaphysics Naturalized”[2]). Third, the question of skepticism can be recast in ontological terms: do the facts about our reasons for our beliefs necessitate the truth of those beliefs? Just as we can ask whether facts about, say, constant conjunction necessitate (entail) causal facts, so we can ask whether facts about our perceptual reasons for belief necessitate facts about the external world. The brain in a vat scenario seems to show that they do not—there is no such entailment, necessitation, supervenience. The problem then has much the same form as other metaphysical problems: we can’t get one kind of fact to add up to another kind of fact. Truths about the external world always go beyond truths about sensory experience—hence skepticism. Skepticism thus reflects the logical arrangement of facts. It would be different if our reasons for belief actually included the facts we believe (“naïve realism”)—and that is a possible metaphysical view. Again, metaphysics is driving the argument.

If this position is correct, it is impossible to claim that epistemology could be basic in philosophy, if that means more basic than metaphysics. It ismetaphysics. What Descartes really did was make one branch of metaphysics more basic than other branches of metaphysics (if we accept the initial claim); more exactly, he made the method of doubt basic in epistemology, which is a branch of metaphysics. He didn’t suppose that epistemology is somehow free from metaphysics—above the metaphysical fray. Indeed, his epistemology is rooted in his metaphysis of mind, because he held that only an immaterial substance could have thought as its essence, which is what knowledge consists in. He didn’t derive his dualism from his epistemology; his view of knowledge rests on a prior metaphysical conception. Whatever knowledge turns out to be, it must be consistent with the fact that the knowing subject is an immaterial being. Nor did anyone else ever make epistemology prior to metaphysics, because that would be to deny that knowledge is an aspect of being, i.e. part of reality. Knowledge is a property that certain objects (subjects) have; and like all properties it has a nature, which can be investigated as such. That is a metaphysical undertaking. We call it epistemology. If someone were to claim that philosophy of mind or philosophy of language were prior to metaphysics, the reply would be the same: these are domains of fact too, and therefore subject to ontological inquiry. Maybe the metaphysics of mind or language could be more basic than other kinds, but they are not more basic than metaphysics in general. It would be the same if someone were to claim that ethics is more basic than metaphysics; the reply would be, “But what about meta-ethics?”

Two metaphysical approaches to epistemology can be distinguished: classical empiricism and Quinean materialism. The ontology of the former includes such items as impressions and ideas, sense data and qualia, while the latter rejects those items and seeks to get by with retinal irritations and the triggering of assent behavior. If someone were to claim that epistemology precedes metaphysics, we could ask him to tell us what kind of epistemic ontology he favors—empiricist or materialist. Then it would be obvious that he already harbors substantive metaphysical commitments. Nowadays people tend to speak of cognitions, data structures, computational operations, informational flow, etc., but again this is metaphysics—claims about what there is. (They might be said to be scientific claims, but then you are adopting a science-based metaphysics.) You can’t get away from ontology in any theorizing, and epistemology is no different. All theories are theories about what there is. The only question is what kindof entity you are going to traffic in, in epistemology and elsewhere. There have indeed been a number of “turns” in philosophy—the linguistic turn, the conceptual turn, the scientific turn, the biological turn, the epistemological turn. But these cannot be characterized as turns awayfrom metaphysics towards some less maddening domain of inquiry, since they are all of them species ofmetaphysics, i.e. ontologically committed areas of thought. In fact, they all raise thorny metaphysical problems, so they offer no respite from the travails of metaphysics. There is thus no firm ground outside of metaphysics from which to survey the old metaphysical problems. So far from being eliminable metaphysics is inescapable.

Is there anyarea of philosophy in which metaphysics disappears, no matter whether that area might lay claim to foundational status? What about aesthetics or philosophy of logic or philosophy of science? Brief reflection shows that the answer is no. Aesthetics must face the question of the ontological status of beauty; philosophy of logic must deal with the nature of logical necessity; philosophy of science must reckon with the status of unobservable entities and the nature of laws. Maybe we can do some medical ethics without confronting metaphysical questions (though the question of moral objectivity is never far away), or perhaps legal philosophy (though the nature of law is ultimately a metaphysical question); but philosophy in general is actually permeated with metaphysical questions. The idea that we can avoid metaphysics is a dream born of frustration—pure wishful thinking.

Why is this (elementary) point about epistemology not generally recognized? I think it is because we have a tendency not to think of ourselves objectively—as one element in a wider world. We feel we stand apart from the world. So it is natural for us to assume that our knowledge of the world is not something inthe world. In epistemology we study ourselves quaknowing subjects, and so it is easy to think that we are not studying a part of the world—the world that includes us and our knowledge. We think there is usover here and the worldover there—meversus it. But this way of seeing things ignores the fact that we are partof the world; and our epistemic states and faculties are just properties of that part. It is true that we can only know the world in virtue of our cognitive faculties, but that doesn’t imply that those faculties aren’t facts of nature among other facts of nature. Once we ascend to a more objective conception of our place in the world, we see that the study of human knowledge is just the study of a certain kind of fact, a kind that concerns the human mind, which itself is just a part of nature. So this aspect of human nature is one kind of being beside others, and so falls within the general theory of being. That theory is just metaphysics or ontology: hence epistemology as metaphysics.[3]

Utility and Knowledge

 

 

A Difficulty With Utilitarianism

 

 

Utilitarianism maintains that the value of a state of affairs depends solely on its level of utility. For a state of affairs to be good (desirable, valuable) it is necessary and sufficient that it contains the best possible level of wellbeing (pleasure, happiness, preference satisfaction). So if two situations contain the same level of utility they must be indistinguishable morally: value supervenes on good feelings (roughly). But consider the following possible states of affairs: (a) people enjoy a level lof happiness and know that lis their level of happiness; (b) people enjoy level lof happiness butdon’tknow that lis their level. In condition (b) they have false beliefs about how happy they are, either underestimating it or overestimating it; while in condition (a) their beliefs are just right. The level of utility is the same in both cases but the epistemic facts are quite different. Are these situations indistinguishable from the point of view of value? It might well be supposed that they are not: (a) is a better situation than (b). If so, utilitarianism cannot be a complete account of value. Knowledge of utility adds value to utility itself. The utilitarian typically assumes that knowledge of utility tracks utility, so there is no gap of the kind exploited by cases (a) and (b); but we can pull these apart in conceivable cases, and then the insufficiency of utility reveals itself.

A number of responses may be made to this simple argument. One response is that the case I described is not logically possible: people can’t be wrong about their level of happiness, since happiness is a mental state and people can’t be wrong about their mental states. However, whatever may be true about mental states in general, it is clearly possible to wrongly estimate one’s state of happiness. A change for the worse may make you realize how happy you used to be (“I didn’t know how lucky I was”), and you might think yourself happier than you really are because you have been so deprived for so long. People are not infallible about their level of wellbeing, though they may be generally reliable. What if you have been brainwashed into believing yourself brimming with joy when in fact you are only moderately content? Don’t people habitually underestimate their level of wellbeing until things turn nasty for them? Happiness is more elusive to knowledge than sensations of pain or experiences of red. If someone asks how happy you are, you might have to pause and reflect before giving an answer.

Second, it may be claimed that the cases don’t actually differ in value: if the utility level is the same, the value is the same. But this is so much biting of the bullet: surely it is better to know than not to know, especially when it comes to one’s own happiness. Isn’t this a rather vital piece of knowledge? A person who went through life believing himself a miserable wretch when in fact he was quite happy would not be living as good a life as one who gets it right; and similarly for someone who regards himself as unusually happy but in fact has a rotten time of it. There is positive value in knowing where you stand happiness-wise.

Third, it might be maintained that the knowledge in question contributes to the level of happiness, and that’s why we judge (a) and (b) differently. That is, knowing your correct level of happiness isa form of happiness: the person who gets it right will therefore be a happier person. If so, we can subsume the value of knowledge under the heading of utility. But this is not plausible: judging your degree of utility correctly does not add to your utility count, any more than other knowledge does. These are two separate things: utility on the one hand, knowledge of utility on the other. Belief isn’t a feeling, so it can’t contribute to the good feelings a person has. Knowledge isn’t a form of pleasure.[1]Whether someone’s beliefs about their own happiness are true or false doesn’t affect how happy they are.

So we are compelled to accept that happiness plus true belief about happiness is better than happiness alone, which means that happiness is not the only valuable thing. Of course, it has been held that knowledge is a value separate from utility, but what the cases of (a) and (b) show is that knowledge of happinesshas intrinsic value. The utilitarian failed to see this because of the assumption of transparency—that happiness will necessarily communicate itself to belief. But once we recognize that that is false we have to accept that knowledge carries its own value, even when (especially when) it is knowledge concerning happiness.[2]Nor can we suppose that such knowledge has merely instrumental value in producing further happiness, because we can stipulate a case in which no such variation in happiness is present—the two people converge exactly and for all time in their utilities while differing in their utility knowledge. Not only is happiness a good thing, but knowledge of happiness is also a good thing—though a good thing of a different type. In a sense, then, utilitarianism is self-refuting, because it presupposes a value it refuses to acknowledge. It assumes that knowledge tracks happiness, thus avoiding acceptance of the separate value of knowledge, but pulling the two apart shows that utility is not enough. The good life is not just the happy life; it is a life in which one is also properly apprised of one’s happiness.

[1]We don’t analyze knowledge by saying: “xknows that pif and only if xbelieves that p, xfeels good about believing that p, etc.”.

[2]Once it is accepted that utility and knowledge constitute separate values, the question of priority arises: which value is more important? Granted limited resources, we have to assign them to promoting our accepted values, so we have to decide how much to allocate to utility and how much to knowledge of utility. This means that we will have to allocate less to utility than we would under the pure utilitarian doctrine, since we have to allocate resources for the production of knowledge of utility too. So the extended utilitarian doctrine will contradict the recommendations of the simple utilitarian doctrine. And there will always be difficult questions about which value to promote in a given situation. The dent in utilitarianism is therefore not trivial.

For Metaphysics

 

 

Metaphysics and Philosophy

 

 

 

In the Epilogue to my book The Character of Mind(1982), entitled “The Place of the Philosophy of Mind”, I wrote: “It would be misguided to infer from the points we have been making that the philosophy of mind is the most basic area of philosophy: probably no part of philosophy can claim that title (except, though trivially, metaphysics).” I will reflect on that parenthesis: Why did I say that metaphysics is trivially (obviously, undeniably) the most basic area of philosophy?

The word “metaphysics” can mean several things, but the meaning that best captures its use in mainstream academic philosophy is “the study of the main kinds of things that there are, and of their interrelations”. If the world is the totality of facts, then metaphysics aims to provide an inventory of these facts, or of the main types of these facts, and to describe or explain how they are related to each other. Thus “metaphysics” is more or less synonymous with “ontology”—the study of being. Slightly more ambitiously, we could say that metaphysics attempts to analyzethe various types of facts—to delve into their essential nature—and to provide a theoryof how the facts are related. It is thus very broad and all encompassing, unlike special branches of philosophy like philosophy of language or ethics. It covers not just this or that part of reality but the whole of it.

It is difficult to see how there could be any objection to metaphysics as so characterized. The various branches of knowledge all seek to identify what exists and to describe its nature (atoms, molecules, organisms, persons, societies, etc); metaphysics just proceeds at a more general and abstract level. Don’t facts come in different types with systematic interrelations between them? If so, can’t we try to say what these are? Of course, there may be bad metaphysics, but how can there not be metaphysics of somesort? The correct metaphysics might be irreducibly pluralist and non-explanatory—there are hugely many kinds of fact and there are no general principles linking them—but that is still metaphysics (to be contrasted with various kinds of monism or dualism). If there is such a thing as what there is (and how could there not be?), there must be truths about what there is, and these truths might be knowable.

Yet metaphysics has been questioned, and is often regarded as an optional part of philosophy—as if we could stop doing it and leave most of the subject intact. On the contrary, metaphysics is indispensable and pervasive—it is the air that philosophy breathes. It isphilosophy. Even the most vehemently anti-metaphysical philosophy is really metaphysics, though just of a different type from other kinds of metaphysics. Consider logical positivism: it declares itself to be against metaphysics—but is it? It subscribes to two central metaphysical theses: (a) that necessity is the same as analyticity, and (b) that meaningfulness consists in verifiability. These are metaphysical theses about the natureof necessity and meaning: they are not pieces of empirical science, verifiable by experiment and experience, and they are rivals to other metaphysical theses about necessity and meaning (truth in all possible worlds, truth conditional theories of meaning). Similarly with such positivist doctrines as emotivism in ethics or instrumentalism in the sciences: these are ontological doctrines, on a par with other ontological doctrines. In the same way a general scientism is a species of metaphysics: the only kinds of facts there are, and the only acceptable theories of those facts, are those discoverable by the empirical sciences. Such a doctrine is not the result of scientific investigation, to be justified by observation and experiment; it is a metaphysical claim about the general content and structure of reality. It is as much a metaphysical doctrine as theistic idealism (though it may be a superior metaphysical doctrine—or not, as the case may be). Positivism and scientism purport to be against alltypes of metaphysics, but in fact they are opposing one type to others (rightly or wrongly). They thus contradict themselves, revealing the unavoidability of metaphysics. Even to say that reality is not susceptible to a metaphysical theory is to say something metaphysical—though of a negative nature.

Nearly all of traditional philosophy is overtly metaphysical in one way or another: from Plato and Aristotle onwards (Spinoza, Descartes, Leibniz, Hume, Locke, Berkeley, Kant, the German idealists and materialists, Hegel, Moore, Russell, early Wittgenstein, Ryle, Quine, Kripke, Strawson, Lewis, Husserl, Sartre, et al). It might be thought there is one clear exception: ordinary language philosophy and the later Wittgenstein—surely theywereboth against metaphysics and also not guilty of engaging in it covertly. But this is wrong: they were doing metaphysics too, though in their own style. They were doing it by paying special attention to ordinary language, not by logic or science or pure metaphysical intuition. They had views about persons, knowledge, intention, sensation, causation, truth, free will, mathematics, ethics, and so on. It is just that they derived these views (or purported to) from an examination of ordinary language. Moreover, they held metaphysical views about meaning: that meaning is use; that not all speech acts are assertions; that the meaning of an utterance can be split into an illocutionary force and a locutionary meaning. None of this is empirical science or history or art criticism: it is theorizing about what is at a very general level. They also held various negative metaphysical opinions: that logical atomism is erroneous, that perception does not involve sense-data, that physical objects are not constructions from experience, that necessity is not in the world, and so on. They didn’t reject metaphysics as such; they just rejected older metaphysical views they didn’t like. Their overall metaphysical position, broadly speaking, was to endorse common sense (not merely describe it, as with “descriptive metaphysics”), and they tended towards ontological pluralism. They distrusted grand unifying systems such as materialism and idealism; their metaphysics emphasized distinctions and variety. Perhaps we could say that they preferred metaphysical modesty–but a modest metaphysician is still a metaphysician. Indeed, their overarching metaphysical position—itself quite ambitious–was that reality does not conform to simple categories and dichotomies. Theirs was a metaphysics of the Many not the One (or even the Two): they held to “multiplicity metaphysics”.

So metaphysics is pervasive, even when officially repudiated, but is it basic? Is it triviallybasic? What about the idea that metaphysics is, or should be, based on philosophy of language? Doesn’t that make the study of language basic? Actually, no, it doesn’t. First, we have to know that language exists, and one can imagine metaphysical views according to which it does not (it’s all an illusion that we ever say anything). Even granting that ontological doctrine, we have to assume that language is meaningful: but according to some metaphysical views meaning is indeterminate, or a creature of darkness, or simply unreal. How could we base metaphysics on language if the whole idea of meaning is shot through with confusion and error? So we would need to combat the eliminative metaphysics of meaning with a metaphysics that finds meaning to be in good order. But now, even once we have got meaning off the ground, there are different metaphysical views about the nature of meaning: Platonism (Frege), psychologism (Grice), behaviorism (Quine), and others. We also need to have some sort of theory of meaning in place, say a truth conditions theory or a verification conditions theory: but these are substantive (and controversial) metaphysical claims about the nature of meaning. We need a metaphysics of meaning before we can use meaning to deliver metaphysical results beyond language. We can’t deduce a metaphysics of time or material reality or mind from considerations about meaning without having some prior view about the nature of meaning. We need to know what kind of thing meaning is.

It is the same with philosophy of mind: we need a metaphysics of mind before we can hope to use considerations from philosophy of mind to adjudicate metaphysical questions, say about ethics or modality. We need to know that minds exist to begin with, what their contents are, and how these contents should be analyzed: specifically, we need a theory of concepts. But this will involve us in the metaphysics of mind: what it contains, the nature of what it contains, the relations between these contents and other things (notably objects outside the mind). We can’t make a given branch of philosophy, either philosophy of mind or philosophy of language, anterior to metaphysics because that branch is itself a type of metaphysics, or essentially includes metaphysics. How could an analysis of concepts be the basisof metaphysics in general, given that there are different metaphysical theories about concepts? If someone tried to make ethics into the basis of metaphysics, they would face the question of what theory of ethics they subscribed to—which would require some sort of meta-ethics. But meta-ethics just is the metaphysics of morality, so we cannot hope to find in ethics a standpoint outside of metaphysics for pursuing metaphysics. Similarly for language and mind.

Metaphysics has always been with us, it has never gone away, and it will always be with us as long as philosophy exists. Even when officially shunned it operates in the background—indeed, it powers its own supposed repudiation. Different kinds of metaphysics wax and wane, and different methods are proposed (science, conceptual analysis, ordinary language, formal logic), but metaphysics is inescapable. Some views may seem more extravagant than others, metaphysically, but even the least extravagant views are still recognizably metaphysical (e.g., there are only sense data, there are only electromagnetic fields, there are only texts). Even someone who believes in nothing but his own current experience is a metaphysician, just a very abstemious one. And for such a thinker his negative metaphysical views are apt to be quite wide-ranging. So, yes, metaphysics is the most basic area of philosophy, trivially so.

Types of Metaphysics

Is Descriptive Metaphysics Possible?

 

 

Strawson draws his famous distinction between two types of metaphysics in these words: “Descriptive metaphysics is content to describe the actual structure of our thought about the world, revisionary metaphysics is concerned to produce a better structure”. This formulation raises puzzling questions. One might have thought that descriptive metaphysics (hereafter DM) aims to describe the actual structure of the world, since that is generally the aim of metaphysics (or ontology); but Strawson inserts the words “our thought about”—so that DM is describing the “structure of our thought”. Thought is an attribute of persons, a psychological attribute. So DM is concerned to describe an aspect of human psychology, notthe world outside of human psychology. Our thought is about the world (what else could it be about?), but DM focuses on thought itself, not the world it purports to be about.

Two questions now arise: (a) why is DM construed to be about human psychology? and (b) what is meant by the “structure of thought”? With respect to (a), the natural objection will be that DM, so characterized, is not a type of metaphysics (a general philosophical theory of reality) but a type of psychology (a description of human thought). DM would therefore be wrongly so called: it is not a general description of the world (a metaphysics) but a general description of the human mind. Maybe answering question (b) can help with this objection, depending on what is meant by the “structure” of thought. It is hard to know what Strawson intends by this word, given that “structure” is usually opposed to “content”. Presumably he does not mean the logical form or grammatical structure of thoughts, since that will not bear on what the subject matter of thought is. Nor can he mean some sort of psychological theory of thought—such as an imagistic theory, or a language of thought theory, or a division into conscious and unconscious thought. If he had written “language” and not “thought” into his definition of DM, we might have naturally taken his talk of “structure” that way—as grammatical or logical structure—but that is hardly the right basis for metaphysics. No, Strawson must mean by “structure” content—what it is that we think. He uses “structure” to mean something like “general” or “basic”, not “local” or “particular”. DM is not about our thoughts concerning weasels and warblers but about our thoughts concerning material bodies in general, as well as space, time, persons, events, causation, and such other typical metaphysical topics. So his idea is that DM describes what we think—the content of it—in very general or basic terms. It will tell us, for example, that people think there are material bodies in space and time, and also persons, with events occurring, and causal relations between the events. It will not tell us that there aresuch things, just that people thinkthere are. As Strawson modestly says, DM is “content to describe the actual structure of our thought about the world”—content to say what we in fact think, without trying to discover what is objectively the case (he could have written “content merelyto describe the actual structure of our thought”).

But that project is not, properly speaking, metaphysics, which should endeavor to tell us what isthe case, not merely what we habitually taketo be the case. What Strawson calls “descriptive metaphysics” is simply not a type of metaphysics—it is a type of psychology or anthropology. It might be pursued using standard psychological or anthropological methods: surveys, experiments, even brain science. It would try to discover what it is that people universally think about reality at a basic level. That task has no logical bearing on what is really the case—it is just the attempt to find out what humans in fact believe. Psychologists do investigate this kind of question: they seek the genetically fixed basic concepts and beliefs that humans share; and they find that concepts like material body, person, space, time, causation, andanimalshow up everywhere. But they don’t take themselves to be doing metaphysics (that’s a job for philosophers), just empirical psychology. To be doing metaphysics one would need to claim (at least) that such beliefs are true: but that is to go beyond merely describing what beliefs people have, and hence beyond what DM, as defined by Strawson, is intended to achieve. His aim, as he clearly states, is the modest one of merely describing human thought.

The problem with this formulation can be brought out by considering other areas in which the Strawsonian distinction might be applied: what about the idea of descriptive ethics, or descriptive philosophy of mind, or descriptive logic? In those cases the project would be to describe the “actual structure of our thought” about value, mind, and logical validity: what do we in fact think about these various areas? No doubt such a subject could be pursued, and it might turn up something of value, but it would not be a type of ethics, or philosophy of mind, or logic. It would tell us what people think in these areas, but not what is true in them; and surely, as philosophers, we want to know what is true about value, mind, and logic—not merely what people thinkis true. For they might be quite wrong, and anyway that is not our proper subject matter—we are interested in the thing itself not in people’s beliefs about it. What would we think if someone proposed a new type of physics called “descriptive physics”, the job of which is to describe what people think about the physical world? We might regard this as an interesting venture in anthropology, but we would not suppose that they had identified a new type ofphysics—which concerns what is true of the physical world, not what people think is true. What they think is often false or incomplete, and anyway physical belief is not our proper subject matter—the physical world is.

The upshot is that the concept of “descriptive metaphysics”, as defined by Strawson, is a confused and misbegotten concept: it seems to denote a type of metaphysics, but it does not, being really a misleading label for a type of psychology or anthropology. Maybe this type of psychology would be of interest to philosophers if it engaged in some substantial conceptual analysis, but it would still be psychology unless it claimed that our conceptual scheme (another phrase of Strawson’s) actually reflects the way reality objectively is. Only then would we ascend to the level of metaphysics: but then we would be doing much more than modestly and contentedly describing “the structure of our thought”. And some reason would have to be given for supposing that what we think istrue, as opposed to other metaphysical views that might be proposed. Actively endorsing our conceptual scheme carries much greater intellectual commitment than merely describing what it contains. After all, people often believe a load of rubbish.

This brings us to “revisionary metaphysics”: does that concept fare any better upon close examination? Of course, all metaphysical systems are revisionary in one sense—they are rivals of each other and aim to supplant the opposing system. But Strawson obviously means revisionary with respect to the metaphysics of common sense—that system of belief that he thinks will be revealed by “descriptive metaphysics”. That is, he supposes that some metaphysical systems contradict the metaphysical beliefs held, explicitly or implicitly, by ordinary people; and if so, these systems are to be called “revisionary metaphysics”. Strawson cites Aristotle and Kant as examples of non-revisionary metaphysicians, and Leibniz and Berkeley as revisionary metaphysicians. So some philosophers endorse the metaphysics of the ordinary person and some reject it, according to Strawson.

All this is highly problematic. First, it is exceedingly unclear whether a given philosopher’s metaphysical system really contradicts common sense: Berkeley notoriously insists that he is at one with common sense, merely differing from its materialist interpreters; and Leibniz might say the same of his system—that nothing in what we actually believe in common sense is really inconsistent with the Monadology. Where does Plato fall? Didn’t he think he was in conformity with common sense, since the existence of universals is taken to be implicit in our ordinary language and thought? Universals are not taken to be alien imports from outside, but to be woven into our ordinary practices. What about David Lewis’s modal realism? What about Hume’s view of causation and the self? Is Descartes’ dualism inconsistent with common sense? I can’t think of a single clear case of a metaphysical system that flatly contradicts ordinary belief, and is taken by its proponents so to do. Indeed, such systems often derive their support from evidence drawn from withinour ordinary beliefs and commitments: they are offered as interpretationsof common sense, and hence are sensitive to how we spontaneously speak and think. Surely metaphysicians characteristically oppose othermetaphysicians, while hoping not to violate basic assumptions of common sense. If they preserve nothingof ordinary belief, they have no leg to stand on, and hence have no claim on our credence. They might jettison a part of common sense, but they cannot realistically reject the whole thing—and in practice they never do. So it is difficult to see who might count as a hard-core revisionary metaphysician in Strawson’s sense.

Strawson makes a fundamental error in the way he sets up the contrast he is aiming to capture: he supposes that our ordinary thought actually contains substantial metaphysical commitments or theories. But it doesn’t: it merely commits us to various kinds of entities, properties, and relations. Thus, as he says, we believe in bodies, space, time, persons, events, causal relations, colors, shapes, and so on. But those are not metaphysicalcommitments; they are merely the commonsense things that metaphysics tries to provide theories of. We ordinarily believe in tables, chairs, and other bodies, but the metaphysician tries to tell us what the natureof these things is, which is clearly a further question. Are they mind-independent entities or are they possibilities of perception? Are they reducible to their atomic components? What is their precise relation to space and to events? We ordinarily believe in persons, but what exactly isa person—a body, a brain, a soul, a connected sequence of mental states, or an ontological primitive? We ordinarily believe in space and time, but are space and time absolute or relative, finite or infinite, continuous or granular? We ordinarily believe in events, but are they a separate ontological category or can they be reduced to objects, properties, and times? We ordinarily believe in causation, but how is causation to be analyzed–by means of necessity, counterfactuals, or constant conjunction? We ordinarily believe that objects have colors and shapes, but are these qualities objective or subjective? In all these cases the metaphysician is discussing something accepted by common sense; he is not arguing withcommon sense—not usually anyway. He is explaining common sense not seeking to revise it.

The mistake is to suppose that our ordinary thought contains actual metaphysical theses—as that everything is mental, or everything is material, or abstract objects exist, or causation can be defined counterfactually, or objects are mind-independently colored. Then a metaphysical system could be genuinely revisionary of what we ordinarily believe about the world. But what we have are ordinary beliefs about ordinary things that are up for metaphysical interpretation and theory. Strawson appears to suppose that a commitment to ordinary things is already a type of metaphysics, but it isn’t—it is just the subject matter of metaphysics. That is precisely why metaphysicians can plausibly claim to be in conformity with common sense, because common sense is not committed with respect to the usual range of metaphysical positions (say, materialism versus idealism). Common sense underdeterminesmetaphysics, in the sense that it is not committed to any specific metaphysical system—merely to the entities such systems seek to explain or analyze.  Strawson may well be right that bodies, persons, space, time, and so on, are indispensable commitments of our conceptual scheme: but such things are the topicsof metaphysics not the resultsof metaphysics. If someone were to assert outright that there are no bodies, persons, space or time, etc, but only lumps of floating ectoplasm, then he would certainly be revising common sense. But no actual metaphysical system in the history of philosophy ever maintains such crazy things—for what conceivable ground could one have for asserting such a proposition? Such systems claim, rather, to say what these generally acknowledged things are (what their nature is), without trying to deny their existence or replace them with a brand new set of objects and properties.

The idea of revisionary metaphysics, as Strawson understands the concept, is therefore entirely toothless and quite irrelevant to the metaphysical disputes that have occupied the history of philosophy. It is simply not a useful or well-defined notion. Nor, as we have seen, is the notion of descriptive metaphysics useful or well defined. So what isthe right conception of metaphysics? The answer is easy: it is the attempt to describe the general structure of the world. This is not the same as the attempt to describe the general structure of our thoughtabout the world; nor is it committed to supposing that metaphysics, so conceived, might contradict common sense. It might, wisely, be completely neutral as to whether it is consistent with common sense, holding that common sense is simply not metaphysically opinionated; or it might strive to demonstrate consonance with common sense. But what it actually aims to do is just to discover what is true of reality, without particularly caring one way or the other about its relation to common sense belief. It certainly will not see itself as being “content to describe the actual structure of our thought”, but will seek instead to assert truths about reality outside of thought—claiming, say, that the world is completely material. We might call this, just to have a label, “veridical metaphysics”—truth-seeking metaphysics. It fits neither of Strawson’s categories, and is really the only kind of metaphysics there is. This subject is the analogue of ethics or epistemology or philosophy of mind or physics or geography. None of these disciplines could call themselves “descriptive X” or “revisionary X” in Strawson’s sense: they are neither descriptive of what people think nor intentionally revisionary of what people think—they simply seek to discover the truth about their domain of interest. Whether that truth contradicts common sense, or supports it, is of no interest to them, since their aim is simply to describe (and possibly explain) reality as it is.

None of this is to deny that the metaphysician may (or must) appeal to common sense in coming up with his theories: that is a question of methodology or evidence. What it does deny is that we can definemetaphysics as describing what people think (or “the structure of our thought”). That’s not what it is about—its subject matter, its domain of interest. Typically, a metaphysician will develop a theory of reality by appealing to the way we naturally think or talk about it–for example, theories about modality; but he does not suppose that his topicis human thought—his topic is the nature of necessity itself. If Strawson had said that the descriptive metaphysician aims to describe the general structure of the world by appeal to the structure of our thoughts about it, then he would have defined an intelligible and useful concept; his mistake was expressly to limit DM to what humans think, i.e. a psychological matter, without regard to the truth about the world. Perhaps at some level that is what he really meant, but it is certainly not what he said. And the point is not trivial, because the project I just defined is precisely the one that would draw the fire of positivists and other skeptics about metaphysics: for how, they would ask, can we ever verify such speculative claims about the general structure of reality, and how can common sense belief ever be evidence for what is true of the objective mind-independent world? Strawson’s project, by contrast, has the look of something not open to such objections, since it limits itself to verifiable matters concerning what humans believe: it is perfectly empirical, verifiable, and even scientific. We just have to find out what people in fact believe—we don’t have to engage in unverifiable abstract speculations about reality.

The trouble is that this innocuous project is simply not a kind of metaphysics; so Strawson has done nothingto rehabilitate traditional (or even non-traditional) metaphysics. He is talking about something else entirely. He is talking, in effect, about folk psychology, not about the fundamental nature of reality. It is ironic that he is often celebrated for bringing metaphysics back into philosophy, after its banishment by the positivists and ordinary language philosophers. If he did have such an influence, it was contrary to his official doctrines and words. It might be thought that he smuggled metaphysics (the veridical kind) back in under the guise of something else entirely: he described it as merely reporting what people think, but in fact he was talking about the genuine article—thus allowing philosophers to go back to what they enjoyed with a clear conscience. The idea of descriptive metaphysics made real metaphysics seem acceptable to people, but they misunderstood what Strawson actually said, and then proceeded to carry on where they had left off. Real metaphysics came back, but only by disguising itself as Strawson’s modest and empirically verifiable “descriptive metaphysics”.

Strawson makes two basic mistakes, which lead him into the misconceived distinction I have criticized. The first is to suppose that common sense (“our conceptual scheme,” “the structure of our thought”) contains a determinate metaphysics that might compete with standard metaphysical systems—such as the view that bodies are possibilities of sensation (phenomenalism), or that persons are a primitive ontological category (Strawson’s own metaphysical position), or that space and time are absolute and mind-independent, or that causation is a matter of constant conjunction, or that events are logical constructions from objects, properties, and times. If it did contain such a determinate metaphysics, it would be obviously inconsistent with a variety of metaphysical theories: but that appears not to be so. Common sense is just not that specific and metaphysically sophisticated. It accepts the existence of various things, but it ventures no opinion on their ultimate nature. The second mistake is to conflate describing our conceptual scheme with endorsing it; or rather, not to keep these as separate as they need to be kept. It is one thing to say what we think; it is quite another to declare what we think to be true. So even if common sense contained a determinate metaphysics, capable of clashing with typical metaphysical systems, that would not show that its metaphysics was correct. To reach the latter conclusion one would need substantial further argument, going well beyond the official business of DM. These assumptions are what would be needed to show that so-called descriptive metaphysics was really a kind of metaphysics (when supplemented with the veridicality claim), and to show that revisionary metaphysics had something to get its teeth into in attempting to revise common sense metaphysics. As it is, neither assumption holds up under examination. The conclusion, then, is that DM is not possible (as a type of metaphysics) and that RM is ill defined. All we have are different (veridical-type) metaphysical systems, proposed by theoretical philosophers, clashing with each other—just as things were before Strawson introduced his influential but misconceived distinction.

The right thing to say is that all metaphysics is descriptive (of reality) andrevisionary (of other metaphysics). No metaphysics is merely descriptive of our thought, that being part of psychology, anthropology, or possibly philosophy of mind. How much metaphysics can plausibly be read into common sense is at best moot. We are committed to various kinds of entities and properties, to be sure, but whether these commitments reach the level of metaphysics proper is dubious at best—substantial theory construction and interpretation is required before we can move from common sense commitments to real metaphysics. It is highly implausible to claim that common sense selects one metaphysical system over other competing metaphysical systems. What Strawson calls “the structure of our thought” (whatever exactly that might be) does not yield a unique and recognizable metaphysical system. Nor is it credible to suppose that common sense is fixed and impermeable to outside supplementation or even revision. Clearly, science has entered common sense at various points, changing it quite fundamentally: the theory of evolution, the extent of the universe, the nature of motion, gravity, electricity, etc. These additions have altered our common sense views of force and causation, of the nature of matter, of how animals came to exist, and so on. Our common sense views of animals and material bodies have changed substantially as a result of biology and physics. Our conceptual scheme is not as conservative and static as Strawson sometimes suggests, though at a very abstract level it has been stable for many thousands of years. His picture appears to be that our ordinary thoughts provide the last word on general questions about reality, but that is far too sanguine a view of what ordinary thought comprises. Also, defending such a view would require doing something quite different from the job Strawson assigns to descriptive metaphysics. It would require a systematic evaluation of ordinary thought, not merely recording what we do in point of fact think. I have said nothing about how such an evaluation might proceed or where it might lead; my point has been just to distinguish it sharply from the project Strawson labels “descriptive metaphysics”.  That project is entirely descriptive, not evaluative.

Let me make a final point about epistemology. If we try to generalize Strawson’ distinction to epistemology, the picture changes because of the role of skepticism. Skepticism can quite legitimately be described as “revisionary epistemology” because it clearly contradicts many of our ordinary beliefs about knowledge and justification: we think we know and can justify a great many things that the skeptic says we cannot know and justify. Our common sense epistemology is quite firmly committed, and so skepticism can easily be seen to fly in its face. So we should have no objection to calling skepticism “revisionary epistemology”. What about “descriptive epistemology”? It is a perfectly feasible enterprise: find out what we ordinarily believe about questions of knowledge and justification. This may be worthwhile and interesting, but again it would be a non sequitur to move from such information to claims about what really isknown or justified—and the skeptic would obviously contest such a move. All this is quite above board and sensible; in particular, we can read a clear epistemology into our ordinary beliefs, so that skepticism can be seen to clash with common sense. It isn’t that common sense is indeterminate with respect to whether we know ordinary facts about the external environment.

I suspect this model was influencing Strawson and his followers, with revisionary metaphysics playing the role of skepticism. That would explain why he set the issues up as he did. But the analogy is imperfect, because the alleged clash between common sense and specific metaphysical views is either unclear or non-existent. Metaphysical theories are offered as theories of the world that may or may not fit with common sense, and which are sometimes justified by appeal to common sense belief (or possibly by science, or direct metaphysical insight); but skepticism is offered expressly as a criticismof common sense, and hence as explicitly revisionary. If you are a philosopher who has little time for skepticism, you will be inclined to go with the epistemological opinions of common sense—as in fact Strawson was himself. This may then color your views about metaphysical theories, which you will see as skeptical with regard to common sense metaphysics. But the cases are crucially dissimilar, and the conceptual apparatus used to deal with one (epistemology) will not carry over smoothly to the other (metaphysics). If so, Strawson’s distinction between descriptive and revisionary metaphysics owes its origin to a misplaced obsession with skepticism.[1]
