Identity and Synonymy It is commonly supposed that “water is H2O” is both known to be true and synthetic (hence a posteriori). I think this is not so. The reason is not difficult to see: if the sentence is known to be true, then speakers will associate the same descriptions with each term (following Leibniz’s […]
Shark Attacks I recently read Francois Sarano’s excellent forthcoming book In the Name of Sharks (sent to me by the publishers because I wrote a review of a book about the octopus in the Wall Street Journal). It puts up a strong case for the preservation of shark populations in the face of dwindling numbers […]
Am I Certain That I Think? Descartes wanted to build human knowledge on a foundation of certainty. He thought the Cogito provided an instance of certainty, and many have agreed (Montaigne was there before him).

A Philosophy of Seeming In “Seeming” I introduced seeming as a sui generis psychological natural kind. Here I will explore its uses in philosophical thought—the kind of impact it would have on philosophy were it to be taken seriously. I won’t repeat what I said in the earlier paper (this one should be read in […]

Suppose we want to understand X: we talk about X, have thoughts about X, but we don’t know the nature of X, or the […]
Naming, Necessity, and Mind I propose to offer an interpretation of Kripke’s Naming and Necessity that has not (I believe) been offered before. I do not say that this interpretation consciously occurred to the author of that work—in fact, I think it didn’t. But I do claim that it illuminates what is going on argumentatively […]
Apropos the Knowledge Argument The knowledge argument tells us that complete physical knowledge of the world is not complete knowledge of the world—in particular, it is not complete knowledge of the mind. How interesting is this conclusion? It depends what we mean by “physical”. Suppose we mean “included in Newtonian physics”, with its talk of […]
