Abstract

The eight relatively short papers in this volume were first presented at the International Institute of Philosophy Entretiens held at Helsinki in 1970. Four main topics are considered: the definition of knowledge, memory, Wittgenstein’s theory of knowledge, and evidence. Representing the first topic, B. A. O. Williams’ paper "Knowledge and Reasons" is chiefly directed toward examining the role of reasons in knowledge. His main thesis is that when speaking in general about knowledge, it is not necessary either that "the knower be able to support or ground his true belief by reference to other propositions" or "that he be in any special state" concerning his belief. Yet it is necessary that, "given the truth of p, it is no accident that A believes p rather than not-p." The author is quick to indicate that this formula is highly schematic and, as an analysis of knowledge, insufficient. A. J. Ayer, as commentator on Williams’ paper, tends to concur with and further amplify a number of Williams’ ideas. However, he does take issue with Williams on two main points: his remarks on the possibility of "radically impersonal knowledge" and his formula that true belief should not be accidental. Concerning the latter, Ayer, while aware of the outline form of Williams’ argument, is "sceptical of its power to yield a precise formula which would differentiate between knowledge and true belief" in a satisfactory manner.
