Would it be quixotic to suppose that quantifiers hold the secret to human success?[1] Could the student of quantification theory be studying the ultimate differentia that separates humans from the rest of nature? That would be a delightful result for the logically minded; and I think there is actually a good deal to be said […]
The concept of meaning is recalcitrant to analysis, elucidation, or theory. There is almost no consensus about what constitutes meaning. We possess the concept, but we don’t know what to say about it—it is opaque to us.

Picture all the possible worlds laid out in logical space in the style of David Lewis.[1] They all objectively exist just like the actual world—real and concrete entities. There are people in some of them who know about the world they inhabit, as we take ourselves to know about the actual world. Now consider skepticism: […]
The demand for reparations for the evils of slavery is often met with the argument that present-day white people are not morally responsible for the sufferings of black people under slavery. That is true, so far as it goes—no one now living is an agent of past injustices committed before they were born. That would […]

A recursive theory of truth for a language in the style of Tarski is thus a theory of meaning for that language. Understanding a sentence consists in grasping its truth conditions. The meaning of a word is […]
“Logical Positivism” That’s an odd label for the view it purports to describe. The most conspicuous feature of the doctrine in question is its negative attitude toward traditional metaphysics: it is a form of philosophical “negativism” i.e. metaphysics is meaningless and should be abandoned. And what is with the adjective “logical” here? Doesn’t every philosophical doctrine […]
The Origin of Ideas Where do our ideas come from? What gives ideas their content? There is an old and natural story about this: call it the “exemplar theory”. Consider the idea of blue (the concept blue, the meaning of “blue”): it arises in the mind by virtue of perceptual contact with exemplary blue things—this contact […]
