Global metaphysical skepticism is the view that we have no knowledge of any substantive metaphysical thesis. Various reasons have been provided in support of global metaphysical skepticism. I provide a new one. The reason, very roughly, is this. Metaphysical theses come together as packages. Such packages are very different from each other. Because the packages are so different, we cannot know of any one of the packages that it isn't true. And because we cannot know of any one of them (...) that it isn't true, we cannot know any substantive metaphysical thesis at all. My paper makes this argument much more precise and defends each of the premises in detail. (shrink)

Widespread and lasting consensus has not been philosophy's fate. Indeed, one of philosophy's most striking features is its ability to accommodate “not only different answers to philosophical questions” but also “total disagreement on what questions are philosophical” (Rorty 1995, 58). It is therefore hardly surprising that philosophers' responses to this metaphilosophical predicament have been similarly varied. This article considers two recent diagnoses of philosophical diversity: Kornblith and Rescher (respectively) claim that taking philosophical disagreement seriously does not lead to metaphilosophical scepticism. (...) The article argues that their confidence is misplaced in so far as both wrongly assume that ordinary, first-order philosophical practice and second-order metaphilosophical reflection are separate enterprises. We can say that the universe consists of a substance, and this substance we will call “atoms,” or else we will call it “monads.” Democritus called it atoms. Leibniz called it monads. Fortunately, the two men never met, or there would have been a very dull argument. (Allen 1997, 171) When will philosophers learn to be less pretentious and arrogant in their claims? One would imagine that the philosophic experiences of twenty-five centuries would have taught them the fallacy of self-esteem! (Schilpp 1935, 233). (shrink)

This article argues for four interrelated claims: Metaphilosophy is not one sub-discipline of philosophy, nor is it restricted to questions of methodology. Rather, metaphilosophical inquiry encompasses the general background conditions of philosophical practice. These background conditions are of various sorts, not only those routinely considered “philosophical” but also those considered biographical, historical, and sociological. Accordingly, we should be wary of the customary distinction between what is proper and merely contingent to philosophy. “What is philosophy?” is best understood as a practical (...) question concerning how members of different philosophical sub-communities identify what is pertinent to their respective activities and self-conceptions. Given –, understanding what philosophy is requires us to take more seriously the social-institutional dimension of contemporary philosophical practice. (shrink)

This essay defends the neo-Quinean approach to ontology against the criticisms of two neo-Carnapians, Huw Price and Amie Thomasson.

The problem of peer disagreement is to explain how you should respond when you and a peer have the same evidence bearing on some proposition and are equally competent epistemic agents, yet have reached opposite conclusions about. According to Christensen's Independence Thesis, in assessing the effect of your peer's disagreement, you must not rely on the reasoning behind your initial belief. I note that ‘the reasoning behind your initial belief’ can be given either a token or type reading. I argue (...) that the type reading is false, but the token reading is extremely weak. (shrink)

I argue that reflection on philosophers who could have been working among us but aren’t can lead us to give up our philosophical beliefs.
