The fact that philosophy is systematic—that philosophical issues are thoroughly interconnected—was a commonplace among nineteenth century idealists, then neglected by analytic philosophers throughout much of the twentieth century, and has now finally started to get some renewed attention. But other than calling attention to the fact, few philosophers have tried to say what it consists in, or what its implications are. -/- I argue that the systematicity of philosophy has disastrous epistemological implications. In particular, it implies philosophical skepticism: philosophers are (...) rationally prohibited from believing any philosophical thesis. The argument goes by way of a new principle that connects inquiry with what is rational to believe. I conclude with a discussion of the relationship between my argument and other, more well-trodden arguments for philosophical skepticism. (shrink)

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)

The revival of analytic metaphysics in the latter half of the twentieth century is typically understood as a consequence of the critiques of logical positivism, Quine’s naturalization of ontology, Kripke’s Naming and Necessity, clarifications of modal notions in logic, and the theoretical exploitation of possible worlds. However, this explanation overlooks the work of metaphysicians at the height of positivism and linguisticism that affected metaphysics of the late twentieth century. Donald C. Williams is one such philosopher. In this paper I explain (...) how Williams’s fundamental ontology and philosophy of time influenced in part the early formation of David Lewis’s metaphysics. Thus, Williams played an important role in the revival of analytic metaphysics. (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)
