Connectives and Necessity In Naming and Necessity Kripke argues against the description theory of names and offers a theory-sketch to be put in its place, often labeled the causal theory. He then extends his critique to apply to common nouns (natural kind terms) contending that they too are not to be […]
Particulars and Universals It is a truism regarding particulars that they cannot be in two places at the same time. This is why alibis work in the law. Types of particulars can have multiple spatially separated instances, but not particulars themselves. Particulars are necessarily singly located things. Of course, they can have parts […]
Existence and Consciousness The idealist sees an essential connection between existence and consciousness: there is no existence where there is no consciousness. Can we make anything of this thought? Suppose an otherwise empty region of space contains an instance of consciousness, say an experience or thought; then we can rightly […]
In the history of philosophy materialism and idealism are regularly opposed to each other: they are conceived as rival metaphysical systems. Each is thought to have its appeal, with oscillation between them, but it is assumed that you cannot be both. They are logically incompatible doctrines. The world is either completely material or it is […]
Wittgenstein concludes his famous section in Philosophical Investigations on games (66) with these words: “we see a complicated network of similarities overlapping and criss-crossing: sometimes overall similarities, sometimes similarities of detail”. This he opposes to the idea that games have a single characteristic that defines them. He follows up this discussion by saying, “I can […]
According to Locke, colors are nothing but powers in objects to produce ideas in our minds. He writes: “What I have said concerning colours and smells, may be understood also of tastes, and sounds, and other the like sensible qualities; which, whatever reality we by mistake, attribute to them, are in truth nothing in the […]
Causation implies laws. A singular causal statement entails a general causal statement. If a caused b, we know that events like a will cause events like b. Thus universality is built into causation—the particular implies the universal.[1] This puts causation in a very special class of relations: it is not generally true that a singular […]
If materialism were true, we should be able to know about matter by introspection; but we don’t, so it isn’t. For materialism is a theory of the nature of mind—what constitutes mental states—and so we ought to know this nature by knowing about the things that have it; but we don’t. If it is the […]
A reasonable expectation of moral philosophy would be that it should identify the good and then characterize it in such a way that doing good is irresistible, or at least desirable. A reasonable expectation of epistemology would be that it should say what knowledge is and then propose an effective method for achieving it. A […]
Today I read this sentence in the book review section of the New York Times: “An interesting , sciencey explanation of the Y chromosome in all it’s vagary and confusion, and the strange trip through the behaviors of the life span of the males of many species.” This is from Mark Morris in By the […]
