On Teletransportation

On Teletransportation

Does teletransportation (henceforth “tele”) preserve personal identity? Does the person survive it?[1] I think not—and I think this is obvious on reflection. The workings of the machine are obscure, but the outlines are clear enough: the subject, body and mind, is vaporized, thoroughly dismantled, and someone just like him or her appears on a distant planet soon after. There is no continuous travel through space as a solid living thing (or non-living if the thing is inanimate); no one is hurtling through space for a few nanoseconds. No, the person is reincarnated at the other end, apparently, not having traced the intermediate steps. The teletransporter doesn’t transport at all; it duplicates after a brief period of non-existence. There are gaps in the individual’s life, but he comes back hale and hearty—allegedly. But is it really so? Why don’t we say that the initial person was destroyed, annihilated, and then a duplicate created soon after? That seems like a perfectly possible scenario: someone is killed, say by being dissolved in acid while sedated, and then a copy is made of that person’s body and brain. No one involved claims that this is a case of survival; it is candidly admitted to be homicide followed by duplication. It is like a photocopier that burns the original while the copy is being made: the original is destroyed but leaves behind a duplicate of itself. The type survives, but not the token. What if Captain Kirk were reduced to ashes in the tele bay by painless cremation and then a copy of him was created on a distant planet from other matter—isn’t that the death of the original man and the creation of an exact copy of him? You can’t undo the killing by producing a copy of the killed man elsewhere. Isn’t it clear that Kirk’s body (that token) was obliterated and another token of that type created? No doubt information derived from the original was used and this is connected causally to the re-creation process, but that doesn’t nullify the act of homicide. Copies often derive causally from earlier entities, but that doesn’t make the two identical. Indeed, the effect of the tele machine is very like the effect of phasers set to full: instant vaporization. The only difference is that a duplicate is produced on the double in the former case. If there was a snafu with the machine and no duplicate appeared, the initial phase of the process would be obvious death; so, the original was clearly deleted, so to speak, before being “transported”. Combine this with the point that multiple Kirks might appear on the distant planet, by design or accident, and they can’t all be numerically identical to the unique Kirk who entered the tele chamber without a care in the world. The entire organism has been obliterated by the machine, as if by a silent nuclear bomb, and the only consolation is that a copy appears in its place somewhere else. But that copy isn’t it. Philosophically speaking, the person is a substance enduring through time and any interruption to that is the cessation of that substance—like any other substance. If you dismantle and dissolve a substance, you destroy it—though you are at liberty to manufacture a copy of that substance. Teletransportation is just that, neither more nor less. It is not translocation, a type of rapid transit, a way of travelling (moving) from A to B. Presumably, a copy could be created at the other end without anyone stepping into the tele chamber; that individual would clearly not be numerically identical to the guy still hanging around on the mother ship minding his business. He never went anywhere; nor did his counterpart come from anywhere near the ship. The case is really no different logically from parentage: you get a copy (possibly exact) but you don’t literally become that individual.

The point of the teletransportation case was to persuade us that personal survival is no more than causal continuity—on the assumption that we agree that the original person survives the process. But he does not; to suppose he does is to conflate personal survival with duplication plus causal connection. So, this argument for a non-substantial view of personal identity doesn’t work. Personality survives (considered as a type), but not the bearer of this personality. So do the body type and person type survive, but not the particular instance of those types. The sad fact is that whenever James T. Kirk steps into the tele machine he is exterminated; the Enterprise has a new captain whenever “he” returns.[2] Same for everyone else: you are seeing different people from week to week with an eerie similarity to people now deceased. It isn’t good old Spock that you now see sparring with Bones, but only a copy of him, destined for replacement before episode’s end. That is the tragedy of Star Trek: all those fine people killed for our entertainment. Kirk should say stoically to Spock as he is about to be vaporized, “It’s been good knowing you, Mr. Spock, let’s hope our future copies are as good as we are.” But it appears that not even Spock has appreciated the homicidal logic of teletransportation (“A most illogical description”, as he might quizzically remark). It is sheer wishful thinking to suppose that these beloved characters survive their various “trips”.[3]

[1] I am obviously alluding to the work of Derek Parfit on personal identity, which I encountered some fifty-three years ago. I am also moved by the work of Michael Ayers on persons and substances.

[2] When Kirk says to Scott “Beam me up Scotty!” the correct answer is “I canne do that Captain—all I can do is destroy you and create a replica of you here on board”. Kirk can only reply “That will have to do Scotty”. Kirk thereupon dies and his replica takes his first grateful breath—just born and he’s already a starship captain! When Kirk is beamed down he is killed and a replica created; similarly for when the replica is beamed back up.

[3] Whenever I now watch an episode of Star Trek, I will reflect that murder (suicide) is being committed on a daily basis; I will feel the appropriate degree of grief. Nor will I welcome the individuals who boldly step from the extermination chamber—they are not the ones of whom I have grown so fond, just impostors. It would appear that star trekking will involve a lot of killing and consequent duplication.

Amorphous Minds

Amorphous Minds

Our world is divided into different objects and kinds of objects—separate objects, distinct kinds. But who or what does the dividing?[1] According to conceptualists, it is minds that divide things up as they see fit, depending on their preferences, needs, conventions, decisions, innate quality space, and sense of similarity; there is no mind-independent carving knife. No minds, no distinguishable objects or kinds of objects. Ontologically, classes result from classification—from mental and linguistic acts. The objective world itself is a blank slate, an amorphous lump, a featureless continuum. Identity depends on identification. According to realists, by contrast, the world is divided up all by itself: it comes to us in segmented form, ready-made, mind-independent. The kinds of nature exist whether minds exist or not. Ontologically, classes result from natural pre-existing divisions, owing nothing to the classifying mind; language, in particular, has nothing to do with it. Which of these two views is correct? Does the ontology derive from the epistemology or does the epistemology derive from the ontology? The naïve answer, and the correct one in my view, is that kind-realism is true: the world autonomously divides into natural kinds that owe nothing to human (or animal) classification—though some kinds are mind-dependent (subjective, human-centered, conventional, pragmatic, etc.). The kinds we recognize are partly reflections of an objective reality and partly a matter of subjective impositions. I think this is completely obvious, embarrassingly so, but a surprising number of philosophers and others adopt the conceptualist position; they are taken in (mesmerized) by the “amorphous lump” conception. Here I intend to refute that position once and for all. Conceptual schemes don’t determine world-orders.

Mind and language are parts of the world: are they then parts of the amorphous lump? Are their internal divisions inherent in them or derived from acts of classification? If the divisions are inherent, then some of reality is subject to taxonomic realism; but if so, why stop there? If concepts and words are divided up by nature, what is to prevent non-mental things from being similarly divided up? On the other hand, if they are not divided in themselves, but inherently amorphous, how can they confer classificatory structure on the rest of the world? How can non-mush arise from mush? How can an unstructured mind create a structured external reality? Suppose there were such a mind, akin to William James’s babyish “blooming, buzzing confusion”: how is that going to give us the world of neatly divided objects and kinds of objects? It can’t. Unarticulated minds can’t give us articulated objects; it would be mush all the way down. So, conceptualism is either inconsistent or impossible. It only stands a chance of working if the mind itself is not brought within its scope. The mind must be conceived as finely tuned, clearly and cleanly articulated, if it is to serve as the foundation of classification.

Very well, it might be said, let us draw in our horns—the conceptualist thesis applies only to the physical world and not to the mental world. But what about the brain? Minds need brains, and brains are physical objects subject to conceptualism—so they too must be part of the amorphous lump. They have no structure save that conferred on them by our (or God’s) classificatory acts. The idea is self-evidently absurd, but let’s allow the conceptualist this much rope—then we have the problem that the articulated mind depends on a formless blob of brain. Or is it that brains only shape minds once they have been suitably conceptualized, so that you don’t get to have a mind until someone has conceptualized your brain for you? An amorphous brainy substance or stuff can hardly give rise to a highly structured mind—from mush we get only more mush. There were neurons in the brain long before anyone had the idea of neurons; neurons are not “mental constructions” that confer structured reality on formless goo. Your brain is not a different object from mine because someone decided to treat it so: it is an objectively discrete object. It is like the body—also a structured object in its own right. It isn’t a mere blob awaiting an infusion of structure. What does this even mean? It’s just rampant metaphor. Things have borders, boundaries, internal components, whether anyone recognizes it or not. The idea that objects are the same or different according to our conceptual practices is pure fantasy—absolute rubbish.[2] Identity and difference are primitive ontological facts.

Behind these reflections on object identity, we have another primitive ontological fact: causality is not mind-dependent. It is not arbitrary to classify things as we do because things don’t act causally in a way that is dependent on our will. The causal powers of an object stem from the object itself not from our manner of conceiving it; causation doesn’t wait on our classificatory predilections and decisions. The amorphous lump has no causal powers, according to conceptualism, so causality must bide its time before entering the world: but this is absurd—the universe was working causally long before conceptualizing creatures came along. If it weren’t, they would never have come along. The natural kind of an object is closely connected to its causal powers, so we go conceptualist about causality if we go conceptualist about kinds. My brain causes my mind, and to do so it must have a determinate structure corresponding to my mind’s structure, so it can’t be a featureless tabula rasa or a piece of formless plasticine. Likewise, species can only cause other species in evolutionary history if they have a determinate specific nature, as a matter of objective fact; they can’t be mere blobs awaiting individuative and causal characteristics conferred by outside observers. These points are surely obvious to the point of banality, and yet they are incompatible with conceptualism taken literally (or is it intended as mere metaphor?). It is true that being first-in-show, say, is an imposed classification on a particular dog, but the difference between dogs and cats isn’t. Would anyone suppose that the difference between rocks and thoughts is a mere matter of arbitrary classification easily altered? (Please don’t tell me that Hopi Indians reject any such distinction and regard rocks as stony spirits.) What is this mania for trying to dissolve all distinctions in nature? Is it ultimately political, as if we are unjustly imposing a class structure on reality that doesn’t belong there? Is it a desire for absolute equality (homogeneity) in all things? If everything is “social construction”, then there cannot be invidious class distinctions de re; hence, nature is not divided in itself but soothingly uniform. All is malleable, moldable. The amorphous lump idea is really an expression of political seamlessness (the unreality of race, gender, merit, etc.) Are claims of identity conceptualism rooted in identity politics? Just a thought.

Here is a more intellectually serious question: is nature necessarily articulated? Could the world have been an amorphous lump? Are any possible worlds inherently blob-like, gooey, formless, undivided? And if there are, could they be subjected to an imposed classificatory scheme? The problem here is that these descriptions are themselves tacitly classificatory; they are at best suggestive metaphors. A lump is a discrete object, bounded and limited, different from other lumps; and amorphous stuff is stuff of a certain kind—cloudlike, desert-like, blancmange-like. But these are things in the articulated world, already classified—clouds, deserts, desserts. The idea of a reality with no nature, no causality, no distinction from other things is a myth, a fantasy, a type of nonsense. True, we can envisage a world less divided and structured than ours—fewer chemical elements or species or types of celestial bodies—but it is still a world divided into objects and kinds. Even a single gas everywhere has a certain nature and divides into distinct areas; it isn’t devoid of all structure (ditto for space and time). Could such a kind-impoverished world be enriched into conceptually imposed kinds comparable in number to ours? I don’t think so: the pre-existing natural kinds of the world set limits to the kinds that can be manufactured mentally. For what use is an elaborate system of classification if reality contains no counterpart to it? There is only so much you can do with all-pervasive hydrogen: you can’t impose animal kinds on it or political systems or types of sport. The world needs to have the resources to justify such classifications, even if they are entirely subjective in origin (e.g., what is good to eat). In fact, every system of classification is rooted in natural classifications—being best-in-show is rooted in human aesthetic responses, which are objective facts. The truth is that all classification is based on natural classes and categories in one way or another—the propensity of nature to fall into kinds and varieties of its own accord: many of them, of many kinds, all distinct from each other. Why this should be so is a difficult question—why not a universe of very few natural kinds? Is it because individual objects cannot exist unless there are many kinds of objects—objects with different shapes, masses, causal properties, etc.? Or is it just a contingent fact about our universe that it contains many kinds of things? In any case, our classifications are created by non-classificatory facts, some physical, some mental. Ontology precedes taxonomy.[3]

[1] I want to acknowledge Michael Ayers’ stupendous book Locke: Epistemology and Ontology (1991) for stimulating my interest in the ontology and epistemology of classification. The position adopted here is close to, if not identical with, his position. Perhaps I go even farther than him in the end. No classification worthy of the name consists of free acts of arbitrary definition. Nature always precedes and determines its description. There is no representational difference without objective difference. Representational facts are parasitic on non-representational facts.

[2] Perhaps I should write “Absolute Rubbish” in order to dignify the rubbish in question: some of the most interesting ideas in philosophy are Absolute Rubbish in my technical sense (idealism, materialism, moral relativism, the verifiability theory of meaning). Philosophy produces Absolute Rubbish as part of its mission—wild attempts to solve intractable problems. Science is not that different.

[3] It is odd that the kind of idealism inherent in conceptualism about categories is not usually accompanied by a more general idealism, as that objects are just mental entities. The thought seems to be that the objects of the world are non-mental but their category or kind is mentally determined: the amorphous stuff is physical but the kind it assumes is mental. This is a very weird position: material substance dressed in mental robes. You would think that reality should be one way or the other.

Cruelty

Cruelty

The cruelty and nastiness currently demonstrated by the Trump administration towards immigrants seems to me to have an exact parallel in the recent cancelling of people deemed to have sinned against feminist orthodoxy.[1] There is no interest in facts (only slogans), no concern with due process (only quick condemnation), no sense of proportionality (only blanket punishment and banishment). Paranoia replaces compassion. It is morally disgusting and vile. The psychopathic heart of America is revealed for all to see. But so is the blindness and stupidity. If you think I am exaggerating, you are part of the problem. You will never be forgiven.

[1] There is even a physical parallel: while the Trump goons gleefully expel “illegals” from the country no matter the suffering and loss caused, university officials expel the alleged miscreant from the university campus—all in the name of “safety”. Merely breaking formal rules (allegedly) is deemed sufficient for extreme expulsive measures. The rhetoric is all about removing “criminals” from our midst so that the “good people” do not become “victims”. The playbook is all too familiar.

Third Letter

Dear Professor McGinn,

Thank you very much for your kind reply. It truly means a great deal to me.

I also want to express how honored I am that you shared both of my letters on your blog. It is a privilege to be featured in a space that reflects your thinking and writing. I very much hope that the long-form interview I am preparing with you will become a work that you, too, will take pride in—and that perhaps it may be something you will want to share with your readers just as generously.

As you mentioned in your message, I was especially struck by the timing: today, quite coincidentally, I began reading your book Sport. So yes, I would very much like to speak with you about your sporting and musical interests. In fact, I would like to speak with you about everything. You are one of the rare philosophers with whom one feels that everything can be talked about freely. I feel deeply honored to have this opportunity, and I owe you a great debt of gratitude for making it possible.

Thank you again for everything. I very much look forward to speaking with you soon.

Warmest regards,

Uğur Polat

FYI


Subject: Looking Forward to Our Upcoming Interview Project

Dear Professor McGinn,

I hope this message finds you well.

I just wanted to say a brief hello and to let you know how excited I am to be continuing preparations for our long-form interview. I’ve been deeply immersed in your writings—revisiting many of your books and finishing the remaining ones. I’ve also begun exploring your co-authored works and other collaborative publications, all of which are offering me valuable insights into the arc of your thought.

In addition to the reading, I’ve been reviewing some of the interviews you’ve previously given, however few they may be, as well as examining your website, colinmcginn.net, in considerable detail. Your blog in particular is a wonderful resource that I find myself returning to often for its clarity and candidness.

As mentioned earlier, the upcoming interview will consist of ten thematic sections, each aiming to delve into a distinct aspect of your intellectual and personal journey. I truly believe that this format will allow us to explore your thought in both depth and breadth.

Finally, if you happen to have any biographical material—photographs, documents, or other personal archive items—that you would feel comfortable sharing for inclusion where appropriate, it would be an honor to incorporate them. These would help enrich the work and offer readers a more vivid sense of your life and legacy. Of course, only if you’re happy for them to be included.

Thank you once again for your generosity and openness. I’m very much looking forward to speaking with you soon.

Warmest regards,
Uğur Polat

Trauma

Trauma

For “trauma” the OED gives us “a deeply distressing experience; emotional shock following a stressful event”. The word comes from the Greek for “wound”; in medicine it means “physical injury”. These words are all on the button. Not just distressing but deeply distressing; a certain type of experience not just an external event (there is something it is like to be traumatized); an emotional shock, sudden and surprising, not just an episode; causing a wound akin to physical injury (like losing a limb) not just a bruise. When subject to trauma the person is traumatized—changed, internally altered, sometimes extremely. I experienced three traumas in a row: professional, personal, and medical. I don’t want to go over the gory details; I want to draw some general conclusions. What is the meaning of trauma? What does it do to the psyche? It is an assault on the self, but it doesn’t kill you (though it can lead to suicide); you have to live with it (it has its own life). It becomes your daily companion. You wake up with it writhing inside you and you go to sleep at night with it still there; you may dream about it constantly. It is forceful and dominating. It causes withdrawal, distrust, uncertainty—you feel that anything might happen at any time, for no reason. In particular, it alters your attitude to other people: you lose confidence in people. It is like losing confidence in your body in serious illness: you feel let down by what you took for granted. Your body becomes your enemy not your friend, as other people become enemies not friends. You seek ways to minimize it, but you know it will never go away: this is now your life, your new reality. It won’t heal (hence deep). Other distressing experiences become harder to deal with—the death of a friend or pet. You have to monitor your state of mental health and not overburden yourself. Unfortunately, this means that you have less space and time for others: you become more self-centered. This is not good. An ill person must focus on his or her own well-being, neglecting other people; so it is with an emotionally traumatized person. There isn’t much that is positive about it. The feeling is sharp and raw, and the associated behavior can be abrupt and impatient. The traumatized individual needs to be given some slack; he is not what he once was. He belongs to another world now. It is not surprising that violence can result, verbal or physical. Not only do you not suffer fools gladly; you don’t suffer them at all.

The most interesting question to me is whether trauma brings new knowledge (in general trauma is not interesting). Does the traumatized person know things the untraumatized don’t? I think the answer is a tentative yes, but not in the cliched sense that it makes you more empathetic or thankful for small things. Rather, it gives you knowledge of the precariousness of human existence: things are going along swimmingly and then suddenly, shockingly, you are wounded deeply, mortally. Your life feels under threat, literally or figuratively. Your normal equilibrium is destroyed. Someone or something is trying to kill you—mentally or physically. They are removing your life support. The world is out to get you and it will not stop. It knows no reason or compassion or human decency; it is a killing machine. The person you once were is no more, just fragments remain. It is a kind of negative metamorphosis: from strong and healthy to crippled and sick. Cancer is a good analogy: it invades you, assaults you, reduces you to a miserable state. It engulfs and cancels. It traumatizes the body and the mind. Other types of psychological trauma also ferociously assail you—they want you dead. But you aren’t dead—you are a living vessel of psychic ruin. Trauma is all about death in one way or another—grief, sorrow, loss. So, what you learn is that death is waiting its opportunity, that it is just around the corner, lurking, unsmiling. Trauma is all about personal destruction. That’s why the death of a loved one can be so traumatizing; in some cases that loved one is yourself. If you knowingly traumatize someone, you are knowingly killing them—psychologically, spiritually. It is soul murder. I think it is good that the concept now exists and is routinely employed, because the phenomenon is only too real. There should really be a whole taxonomy of trauma, ranging from minor to annihilating. People should talk about their traumas, share them, have trauma parties. Trauma therapy should be free of charge. Trauma education should be mandatory. Trauma should be respected. There should be trauma nurses. You may learn something you didn’t know before by being made subject to it, though you may wish you never acquired this piece of knowledge. Hell, there should be a trauma philosophy.[1]

[1] Isn’t hell a place of endless trauma as well as endless torment? Torture causes pain now and trauma later. Battle trauma is the most obvious case, with a visible cause, but trauma comes in many forms, many not visible. Memory is integral to it—the vivid recollection of particularly awful experiences. If trauma could be weaponized, it would be (and has been in some cases).

Dream Laser

Dream Laser

Steven Pinker once said of me, “McGinn is an ingenious philosopher who thinks like a laser and writes like a dream”. Nicely put, Steve, memorable, poetic. But what exactly does it mean? Is it true? We should certainly take it seriously because (a) Pinker is one the world’s top cognitive psychologists, (b) he is an exceptional thinker himself, and (c) he is a fine writer and an expert on language. What did he mean by saying I think like a laser? The word is an acronym for “light amplification by stimulated emission of radiation”, but its literal meaning is beside the point; he means the word metaphorically. It can mean highly focused, as in “He was laser focused on the problem”. But I think Pinker means to evoke the bright and cutting aspects of laser beams, their high precision burning, perhaps their slightly frightening destructive power (remember that terrifying scene in an old James Bond movie?). So, he is referring to (what he takes to be) my uncommon penetration, clarity, and precision. Okay, we understand that. What about writing like a dream? He obviously doesn’t mean that I write in a meaningless, chaotic manner, like a disjointed nonsensical dream. He means the quality the dictionary describes as “a wonderful or perfect person or thing”—something transcending the usual imperfect world of waking life. Dream writing is writing that takes you to a better place, a type of paradise. Now what was Pinker trying to convey by these metaphors? Would he say that many people have these qualities? I don’t think so: he meant to say that they are rare, perhaps especially among philosophers. Other philosophers are apt to think like a shovel and write like a hangover. Would he describe any other philosopher in these terms? I rather doubt it; he meant to be singling me out. That is the indicated conversational implicature: only McGinn can be so described—though others may come close. Some may think like a laser but not write like a dream; others may write dreamy prose but not have the laser intelligence. That seems to be his intent anyway.

What do I think of this description? What strikes me is that I would not describe any philosopher this way, living or dead. I would say that many philosophers have been brilliant thinkers and excellent writers, but I wouldn’t say anyone thinks like a laser and writes like a dream. Some scientists have laser-like intellects and some writers have dreamlike prose, but not philosophers. It is the idea of cutting that stands out: cutting through an issue, getting to its heart, surgically dissecting it. In the case of dream writing, the only writer I would describe as writing like a dream is Nabokov (possibly Flaubert), though there have of course been numerous fine writers of fiction. This to me is the most intriguing part of Pinker’s description: that I don’t just write well, or even very well, but like a dream. And I do see his point: I always feel in a trance as I write, as if I am having a pleasant dream. I think he was onto something: the combination of the cutting and the dreamlike. Then there is the use of “ingenious”: I don’t think I was being singled out for this quality; lots of philosophers are ingenious. But they are not intellectually laser-like and verbally dreamlike. I could have been laser-like and dreamlike without being ingenious, and I could have been the converse; but, according to Pinker, I am all three. The one that I like the best is the dream comparison: ingenuity and lasers are all well and good, but dreams are something special.[1]

[1] I am well aware of the egotism involved in writing about this subject, but someone has to do it. I have not discussed this remark of Pinker’s with him, though we are now friends; we didn’t know each other at the time he said it. One day I will ask him to expand (or maybe not).

Ontological Rationalism

Ontological Rationalism

Ontological rationalism is the view that the world is intrinsically intelligible.[1] Roughly, the world is intelligible if and only if it obeys laws with some kind of necessity; it is unintelligible if it is completely random, contingent, chaotic. An unintelligible world is one in which anything can happen at any time, e.g., night falling if you blink on a particular Wednesday but an explosion occurring if you blink the next day. Geometry is intelligible; astrology is not (or pick your favorite pseudoscience or fantasy world). Philosophers and scientists of the seventeenth century came to feel that Aristotelian metaphysics was not intelligible; by contrast, mechanism was intelligible. Machines are intelligible, but not substantial forms. Thus, Hobbes, Descartes, Locke, Boyle, Newton, Hume, and many others advocated mechanism as a theory of the physical world: they were all ontological rationalists. The world works according to laws concerning extended corpuscular objects in motion. Locke and Hume were epistemological empiricists but ontological rationalists (they didn’t think that physical reality consisted of impressions and ideas). They thought that mechanism was the best theory available as a description of the physical universe, rendering it intelligible and rationally organized. The question I want to ask is whether these philosophers were ontological rationalists about the mind: were they, and did they intend to be, ontological rationalists about knowledge in particular? Did they think their epistemological empiricism was a form of ontological rationalism? If so, were they right so to think?

Presumably, they did think the mind is intelligible—a place of rational order. It would be strange to insist on the intelligibility of the physical world but admit that the mental part of reality is intrinsically unintelligible. They thought that knowledge is subject to a rational theory of some sort—indeed, they thought they possessed such a theory (as did Descartes). But they didn’t think that the mind is subject to the same theory as body—the mechanistic theory of composite extended objects in motion. They didn’t think you could apply Newton’s laws of motion to the mind (Hobbes is the exception, being a materialist). Their ontology consisted of impressions and ideas, not chunks of matter; they spoke of deriving ideas from impressions, not of motion through space. They didn’t announce that ideas move through space in a straight line unless deflected by a countervailing force. The question, then, is whether their actual theory provides an alternative kind of rationalist ontology: is it perhaps mechanistic if not mechanical? Is it like physical mechanism? This is not an easy question to answer, but I think the answer is no, despite the way the theory is presented: empiricism is not a rationalistic theory of the mind—of the way knowledge is acquired and what it is. But it will turn out that in this respect it isn’t really all that different from the mechanistic theory of matter: both are at best approximations to a fully rationalist ontology.

The first law of empiricism is that all ideas are copies of impressions: ideas derive from impressions by a process of (imperfect) duplication—faint copies, but still recognizably the same. Bodies tend to retain their motion (at rest or moving); impressions tend to retain their qualitative character as they morph into ideas (blue impressions don’t produce red ideas). Just as all motion comes from other motion or an impelling force, so all ideas come from antecedent impressions. There are necessary laws at work in both cases—hence true generalizations. Similarly, just as bodies are made up of parts, down to minute corpuscles, so ideas are made up of parts, down to their simplest components (mental corpuscles). The entities and processes are analogous but not identical. But—and this is crucial—there is no geometry to back up the laws and processes alleged. There is thus no logical deduction; instead, there is mere plausible assertion. How do impressions produce ideas—by what mechanism? We are not told; not by contact, to be sure. The idea is magically created from the impression (we are inclined to think of colors fading in sunlight over time). But isn’t the impression intrinsically inert—why should it spawn ideas (images) at all? Dabs of paint don’t spontaneously generate faint copies of themselves! Couldn’t there be impressions that lazily refuse to copy themselves in attenuated form? Impressions can come and go and leave no residue behind. Isn’t this all rather rabbit from a hat? Do we need to resort to God to explain how impressions lead to ideas, given that they lack the power to do it themselves in a quasi-mechanical way? And how exactly do ideas combine to form complex ideas—by what force or mechanism do they achieve this feat? Are they adhesive in some way? Is this a weird form of gravitational attraction? Can they break apart? It is really nothing like material composition. What kind of machine is made up of idea parts? Also, what is this notion of a tabula rasa? We are told the mind is like a blank slate or empty cabinet, but this is just metaphor—what is the actual nature of this mental vacuity? How are ideas inscribed on it? Is there some kind of mental ink? We are swimming (drowning) in physical metaphors, producing illusions of intelligibility. We really have no idea what is going on in the mind, intelligibly, when knowledge is acquired, according to the empiricist theory—nothing analogous to physical mechanics anyway. There is no Principia Epistemologica analogous to Newton’s Principia Mathematica. The empiricists may have intended to produce a theory of mind like the mechanical theory of matter, but they failed in that laudable endeavor; so, they failed to make good on their ontological rationalism in relation to the mind and knowledge. It’s all metaphor and hand-waving, no better than the old Aristotelianism. If this were all there is to it, the mind would not be an intelligible part of reality; it would be nothing like the (supposed) transparent machine envisaged by the new mechanists. The empiricist mind is not a geometric mechanism, or even a simulacrum of one.

Now, Locke did not believe that the mechanism of his day provided the complete and final answer to the mystery of nature. He thought cohesion and solidity were left unexplained. What he believed is that it provided the best available model for what a science of nature should look like—faint glimmerings of the truth perhaps. I don’t doubt that Hume thought the same, given his views on Newton (“mysteries of nature” etc.). Thus, Locke was deep down a skeptical agnostic about the nature of matter: mechanism was on the right lines but not the final story. Of course, he was right about this, as the future of physical science showed (electromagnetism etc.). Mechanism was not in fact the sought-for scientific vindication of philosophical ontological rationalism. But he didn’t take the same skeptical view of his own theory of the mind. That is, he didn’t see that his official theory of knowledge had serious gaps and weaknesses, being at best part of the truth—glimmerings but not a final theory. He should have been a cautious and modest empiricist, not the confident and rash empiricist he comes across as. He was so anxious to defend his empiricist principles that he forgot his ontological rationalism: he should have been a double mysterian. Matter is a mystery, but so is mind. Motion is a mystery, but so is knowledge. Empiricism should have been offered as a first approximation, a stab in the dark, just like mechanism—the best we have managed to come up with so far. He should have said, “My hunch is that all knowledge, or nearly all, comes from experience; but I don’t have much idea how, and I certainly don’t have a worked-out intelligible theory of how it happens.” He could then have gone on to attack the rival theory of epistemological rationalism. But he was an over-confident skeptic, an agnostic true believer, when it came to his own theory of the knowing mind (same for Hume and later empiricists). You can’t really be an ontological rationalist and a committed dogmatic empiricist in the classic mold.

I will now say a few words about another problem with empiricism that I have never seen discussed. It has a certain brutish punch in the solar plexus quality to it. Can empiricism explain the knowledge it purports to express? What I mean is this: empiricism is supposed to be a theory that we know to be true, but can the theory be known to be true according to empiricist principles? The theory employs the concepts of impression and idea, and it proposes a law of idea generation. Given that the theory consists of ideas, these need a basis in antecedent impressions. Thus, the theory needs an idea of impressions, an idea of ideas, and an idea of the relation of idea generation. This means we need an impression of impressions, an impression of ideas, and an impression of idea generation. Where do these impressions come from? Not from the senses: we have no visual impression of impressions or visual impression of ideas or visual impression of idea generation—we don’t see impressions and ideas and the relation between them. Evidently, then, we must get these ideas by reflection on our own consciousness. But are we conscious of having an impression of impressions or of ideas or of idea generation? What is an impression of an idea? We know we have ideas, but do we have impressions of ideas? That’s a funny sort of creature, is it not? Isn’t it under suspicion of not existing? But unless it exists the knowledge that empiricism is true can’t exist, according to empiricism. So, the empiricist theory of knowledge cannot explain knowledge of itself. It needs one too many impressions. And are we to think that an impression of an idea can lead to the idea of an idea? Do we extract the idea of an idea from the impression an idea creates while existing in our consciousness? Isn’t this total mythology? And what about our supposed knowledge that all ideas derive from impressions—do we have impressions of this derivation occurring in our consciousness? Have you ever felt an impression causing an idea? You know impressions can cause memories in the form of images, but do you ever have an impression of this occurring? I don’t, and neither does my cat (I asked him). So, we ought not to have knowledge of any such thing, if empiricism is true. Rationalism can explain such knowledge—it comes from innate ideas—but empiricism runs into trouble with the question. We have more ideas than empiricism can explain (e.g., the missing shade of blue, necessity, the self, etc.). It turns out that the theory itself needs more ideas that it can explain; in particular, it needs an inner sense along with associated impressions, such as impressions of ideas (images). What would a sensation of an image be (if not the image itself)? How would this sensation give me the idea (concept) of an image? Do my thoughts give me images of thoughts via some sort of impression of them? Ditto for desires, emotions, intentions, etc. Would it be possible to have impressions of ideas and yet not form an idea of ideas? None of these questions is so much as raised by empiricists, and yet they are crucial to the question of whether empiricism is knowable according to its own tenets. If empiricism is true, it is not knowably true. That is logically possible, but not anticipated by its defenders.[2]

[1] For some serious background see Michael Ayers, Locke: Epistemology and Ontology (1991), especially volume II, part II, “God, Nature and the Law of Nature”. I use some of his terminology as well as his historical scholarship. I have never read a better book on the history of philosophy.

[2] The hold of empiricism on the philosophical mind is itself something of a mystery: we readily fall for the theory, but its problems are manifold and central. Is this because the correct theory is far from our comprehension? We fall for empiricism because nothing else occurs to us as remotely cognizable. Better to believe something than nothing. And empiricism is not completely wrong. The problem of knowledge is like the mind-body problem in this respect. Empiricism is the logical analogue of dualism—both are natural (inevitable?) errors.
