In some previous work, I tried to give a concept-based account of the nature of our entitlement to certain very basic inferences (see the papers in Part III of Boghossian 2008b). In this previous work, I took it for granted, along with many other philosophers, that we understood well enough what it is for a person to infer. In this paper, I turn to thinking about the nature of inference itself. This topic is of great interest in its own right (...) and surprisingly understudied by philosophers. A correct understanding of inference promises to shed light on a number of important topics. In particular, it threatens to undermine the sort of concept-based story about entitlement to which I had previously been attracted. (shrink)

I. Recent years have witnessed a great resurgence of interest in the writings of the later Wittgenstein, especially with those passages roughly, Philosophical Investigations p)I 38 — 242 and Remarks on the Foundations of mathematics, section VI that are concerned with the topic of rules. Much of the credit for all this excitement, unparalleled since the heyday of Wittgenstein scholarship in the early IIJ6os, must go to Saul Kripke's I4rittgenstein on Rules and Private Language. It is easy to explain why. (...) To begin with, the dialectic Kripke uncovered from Wittgenstein's.. (shrink)

Hilary Kornblith’s book is motivated by the conviction that philosophers have tended to overvalue and overemphasize reflection in their accounts of central philosophical phenomena. He seeks to pinpoint this tendency and to correct it. -/- Kornblith’s claim is not without precedent. It is an oft-repeated theme of 20th-century philosophy that philosophers have tended to give ‘overly intellectualized’ accounts of important phenomena. One thinks here of Wittgenstein, Ryle and many others. -/- One version of this charge is that philosophers have tended (...) to appeal to higher-order thoughts when first-order thoughts about the world are all that’s needed. -/- A more specific version of this charge is that philosophers have tended to appeal to second-order thoughts with normative, or quasi-normative, contents when all that’s needed are first-order thoughts with factual contents. -/- It is this second version of the charge that Kornblith is particularly interested in pressing. Although he doesn’t spell it out, the connection between this project and Kornblith’s previous work on naturalistic conceptions of epistemology should be fairly obvious. Very roughly, if you want humans to look a lot closer to the lower animals, then you’d better think that most central human abilities can be explained without appeal to reflection and without appeal to normative thought. -/- What’s good and important about Kornblith’s book is that he gives this charge a sustained and illuminating treatment. He looks in detail at accounts of knowledge, reasoning, epistemic agency, free will and normativity; he identifies sympathetically some of the temptations to think that we must resort to second-order resources to explain these phenomena; and he attempts to show that the appeal never works and is, in any case, not needed, since first-order accounts manage very well.

According to a very natural picture of rational belief, we aim to believe only what is true. However, as Bernard Williams used to say, the world does not just inscribe itself onto our minds. Rather, we have to try to figure out what is true from the evidence available to us. To do this, we rely on a set of epistemic rules that tell us in some general way what it would be most rational to believe under various epistemic circumstances. (...) We reason about what to believe; and we do so by relying on a set of rules.... (shrink)

In this book Saul Kripke brings his powerful philosophical intelligence to bear on Wittgenstein's analysis of the notion of following a rule.
