New Essays On The A Priori

A priori knowledge and justification have long played a prominent part in epistemology and the theory of meaning. This text offers a variety of approaches to the a priori, examining its role in different areas of philosophical enquiry.

The topics of a priori knowledge and a priori justification have long played a prominent part in epistemology and the theory of meaning. Recently there has been a surge of interest in the proper explication of these notions. These newly commissioned essays, by a distinguished, international group of philosophers, will have a substantial influence on later work in this area. They discuss the relations of the a priori to meaning, justification, definition and ontology; they consider the role of the notion in Leibniz, Kant, Frege and Wittgenstein; and they address its role in recent discussions in the philosophy of mind. Particular attention is also paid to the a priori in logic, science and mathematics. The authors exhibit a wide variety of approaches, some remaining sceptical of the notion itself, some proposing that it receive a non-factualist treatment, and others proposing novel ways of explicating and defending it. The editors' Introduction provides a helpful route into the issues.

This book deals with questions about the nature of a priori knowledge and its relation to empirical knowledge. Until the twentieth century, it was more or less taken for granted that there was such a thing as a priori knowledge, that is, knowledge whose source is in reason and reflection rather than sensory experience. With a few notable exceptions, philosophers believed that mathematics, logic and philosophy were all a priori. Although the seeds of doubt were planted earlier on, by the early twentieth century, philosophers were widely skeptical of the idea that there was any nontrivial existence of a priori knowledge. By the mid to late twentieth century, it became fashionable to doubt the existence of any kind of a priori knowledge at all. Since many think that philosophy is an a priori discipline if it is any kind of discipline at all, the questions about a priori knowledge are fundamental to our understanding of philosophy itself.

Publisher Description

This book is a collection of essays concerning the concept and existence of a priori knowledge, and the relationship between a priori knowledge and the related concepts of necessary truth and analytic truth.

For centuries philosophers have attached much importance to a priori knowledge, but recent work in epistemology and experimental philosophy has questioned this. Leading philosophers discuss explanations of the a priori, challenges to its existence, the status of intuition, and the justification of belief—topics at the centre of current debate.

This volume provides philosophers and students with important contemporary investigations on a priori knowledge by well-known and influential philosophers, including A. J. Ayer, W. V. Quine, Barry Stroud, and C. I. Lewis.

Provides an important historical record of the development of investigations into the a priori during a critical period in which it emerged from being a rather arcane topic in the epistemological literature to occupying a central role.

The topic of a priori knowledge has been central to analytic philosophy for the past two centuries. Casullo's book, based on previously published and unpublished work, systematically addresses questions that have, since Kant, formed the core of the debate.
