Saul Kripke is one of the most original and creative philosophers writing today. His work has had a tremendous impact on the direction that philosophy has taken in the last thirty years and continues to dominate some of its most fundamental aspects. Given Kripke's importance it is perhaps surprising that there is no introduction to his philosophy available to the general student. This book fills that gap. As much of Kripke's work is highly technical, the book's central aim is to (...) provide clear exposition of Kripke's ideas in a form that is understandable to a beginning readership as well as a commentary on them that more advanced students will find useful. The book begins with a discussion of Kripke's early work on modal logic, which provides the foundation for many of his later philosophical contributions, before examining in detail Kripke's central ideas and arguments contained in Naming and Necessity. In further chapters, Kripke's work on semantic paradoxes and his theory of truth are outlined as well as his controversial interpretation of Wittgenstein's famous private language argument. Kripke's ideas are situated alongside those of his precursors and some of the most important and interesting responses to them are explored. The reader is thus able to appreciate the path-breaking nature of Kripke's contributions, how they have challenged fundamentally traditional interpretations, and how they have sparked some of the most important philosophical debates of recent years.

In a recent paper Robert J. Richman joins a host of doubters who question Gettier's claim that knowledge is not justified true belief. Richman's scepticism of Gettier's counterexamples to the traditional analysis of knowledge stems from what he says are two basic defects in the examples. One defect is that Gettier employs the Principle of Deducibility for Justification which Richman argues is false. The second defect is based on “the obvious consideration that a belief which is justified on the basis (...) of one set of facts or assumptions need not be justified on the basis of a different set.” I shall consider each of these alleged defects and argue that Richman has not shown that in fact they are defects and that Gettier's counterexamples do in fact show that knowledge is not justified true belief.The Principle of Deducibility for Justification states that for any proposition P, if P entails Q and S correctly deduces Q from P and accepts Q as a result of this deduction, then Sis justified in believing Q.

One of the most important insights that Russell had in presenting his philosophy of language was his view of singular definite descriptions. Russell held that singular phrases of the form ‘the so-and-so’ should not be viewed as names, but rather incomplete symbols which can be said to have meaning only in a context. We should not represent the sentence The inventor of bifocals is bald.as a simple subject-predicate sentence of the form ‘Fa.’ but rather as a complex existential sentence. According (...) to Russell we should analyze as There is a unique x such that x invented bifocals and x is bald.Moreover, if Russell's analysis is correct then the proposition expressed by will be true in a given circumstance provided that there is a unique inventor of bifocals who is bald in that circumstance.

I will focus on what seems to be a problem for Kripke’s position with respect to certain necessary a posteriori truths and true negative existentials. I shall tentatively suggest that within Kripke’s work a solution to the problem in question can be found provided one is willing to distinguish statements from propositions.

Alvin Plantinga has recently argued that there are certain propositions which are necessary but known only a posteriori. If Plantinga is correct then he has shown that the traditional view that all necessary truths are knowable a priori is false. Plantinga's examples deserve special attention because they differ in important respects from other proposed examples of necessary a posteriori truths. His examples depend on a certain conception of possible worlds and in particular on his conception of the actual world. It (...) will be argued that these examples of necessary a posteriori propositions can be understood in two different ways. According to one way of understanding Plantinga, the propositions turn out to be contingent a posteriori truths, and according to the other way they turn out to be necessary a priori truths. The plausibility of Plantinga's position is due to a confusion between the two possible interpretations. (shrink)
