Knowledge And A Priori Justification

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.

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 Casullo's book, based on previously published and unpublished work, systematically addresses questions that have, since Kant, formed the core of the debate.

A comprehensive defence of the rationalist view that insight independent of experience is a genuine basis for knowledge.

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.

One of the most firmly entrenched beliefs of contemporary philosophy is that the only way to analyze a concept is to state its truth conditions. In epistemology this has led to the search for reductive analyses, to phenomenalism, behaviorism, and their analogues in other areas of knowledge. Arguing that these attempts at reductive analysis have invariably failed, John L. Pollock defends an alternative theory of conceptual analysis in this book. The author suggests that concepts should be analyzed in terms of their justification conditions rather than their truth conditions. After laying a theoretical foundation for this alternative scheme of analysis, Professor Pollock applies his theory in proposing solutions to a number of traditional epistemological problems. Among the areas of knowledge discussed are perception, knowledge of the past, induction, knowledge of other minds, and a priori knowledge. Originally published in 1975. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

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.

In recent years many influential philosophers have advocated that philosophy is an a priori science. Yet very few epistemology textbooks discuss a priori knowledge at any length, focusing instead on empirical knowledge and empirical justification. As a priori knowledge has moved centre stage, the literature remains either too technical or too out of date to make up a reasonable component of an undergraduate course. Edwin Mares book aims to rectify this. This book seeks to make accessible to students the standard topics and current debates within a priori knowledge, including necessity and certainty, rationalism, empiricism and analyticity, Quine's attack on the a priori, Kantianism, Aristotelianism, mathematical knowledge, moral knowledge, logical knowledge and philosophical knowledge.

The book sets out to analyze the notion of a priori justification and of a priori knowledge. The most influential explanations of the a priori within the contemporary analytic tradition are analyzed. It is shown that the theories which group around the notion of implicit definition ultimately entail that the propositions which can be known a priori are to be analyzed along conventionalist lines. It is argued that the notion of objective a priori knowledge requires a commitment to the existence of a faculty which is the source of and justifies that kind of knowledge. The existence and functioning of this faculty cannot be explained within a strictly naturalistic set of constraints. Attention to the phenomenology of justification (validation) both of observational and purportedly a priori statements however reveals that the naturalistic demands are based on an asymmetry thesis among perception (and credited genuine sources of justification) and rational insight which is false. Therefore it is argued that a corresponding symmetry thesis must be accepted, according to which rational insight should be regarded as a justification-conferring faculty. In the final part of the book it is argued that Husserl’s conception of the analytic/synthetic distinction, and of concept constitution, allow for an objective interpretation both of analytic and synthetic a priori knowledge.

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.
