David Hume's Enquiry concerning Human Understanding is the definitive statement of the greatest philosopher in the English language. His arguments in support of reasoning from experience, and against the "sophistry and illusion"of religiously inspired philosophical fantasies, caused controversy in the eighteenth century and are strikingly relevant today, when faith and science continue to clash. The Enquiry considers the origin and processes of human thought, reaching the stark conclusion that we can have no ultimate understanding of the physical world, or indeed (...) our own minds. In either sphere we must depend on instinctive learning from experience, recognizing our animal nature and the limits of reason. Hume's calm and open-minded skepticism thus aims to provide a new basis for science, liberating us from the "superstition" of false metaphysics and religion. His Enquiry remains one of the best introductions to the study of philosophy, and his edition places it in its historical and philosophical context. (shrink)

The topic of a priori knowledge is approached through the theory of evidence. A shortcoming in traditional formulations of moderate rationalism and moderate empiricism is that they fail to explain why rational intuition and phenomenal experience count as basic sources of evidence. This explanatory gap is filled by modal reliabilism -- the theory that there is a qualified modal tie between basic sources of evidence and the truth. This tie to the truth is then explained by the theory of concept (...) possession: this tie is a consequence of what, by definition, it is to possess (i.e., to understand) one’s concepts. A corollary of the overall account is that the a priori disciplines (logic, mathematics, philosophy) can be largely autonomous from the empirical sciences. (shrink)

'My endeavour in these pages is to explain the main features of the method of philosophizing which we, the Vienna Circle, use, and by using try to develop further. It is the method of the logical analysis of science, or more precisely, of the syntactical analysis of scientific language.... The purpose of the book -- as of the lectures -- is to give a first impression of our method and of the direction of our questions and investigations to those who (...) are not yet acquainted with them.' -- From the Preface.

In this book, the author of "Language, Truth and Logic" tackles one of the central issues of philosophy - how we can know anything - by setting out all the sceptic's arguments and trying to counter them one by one.

In these challenging pages, Unger argues for the extreme skeptical view that, not only can nothing ever be known, but no one can ever have any reason at all for anything. A consequence of this is that we cannot ever have any emotions about anything: no one can ever be happy or sad about anything. Finally, in this reduction to absurdity of virtually all our supposed thought, he argues that no one can ever believe, or even say, that anything is (...) the case. (shrink)

Descartes held the view that a subject has infallible beliefs about the contents of her thoughts. Here, I first examine a popular contermporary defense of this claim, given by Burge, and find it lacking. I then offer my own defense appealing to a minimal thesis about the compositionality of thoughts. The argument has the virtue of refraining from claims about whether thoughts are “in the head;” thus, it is congenial to both internalists and externalists. The considerations here also illuminate how (...) a subject may have epistemicially priviledged and a priori beliefs about her own thoughts. (shrink)

In this paper I outline and defend an introspectionist account of authoritative self-knowledge for a certain class of cases, ones in which a subject is both thinking and thinking about a current, conscious thought. My account is distinctive in a number of ways, one of which is that it is compatible with the truth of externalism.

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

The question whether we can have a priori knowledge, and if so to what extent, has lain at the center of philosophy practically since the beginning. For many philosophers, including Plato, Leibniz, Kant, Frege, Russell, Wittgenstein and most of the Logical Positivists, to name just a few, it seems to have been the problem around which everything else was made to turn. It's an interesting question why philosophers have been so obsessed with this problem and why they have been inclined (...) to assign it so much importance. One reason, no doubt, has to do with its relation to the possibility of philosophy itself. Although it has become fashionable in some circles to pretend otherwise, I don't really see that anyone out there has much idea how analytic philosophy is to be done, if not a priori; in particular, I don't really see that anyone has much idea how it is to be done without a hefty helping of a priori conceptual analysis....
