: T.L. Short's book argues that Peirce's early theory of signs was flawed, and that the development of his mature theories required a new start and the rejection of some fundamental doctrines from the earlier view. While agreeing that Peirce's view of signs changed and agreeing on the new developments that were of most significance, I express some doubts about Short's diagnosis of why such changes were required. I argue that the changes were required, not by internal inconsistencies in the earlier position, but rather by the need to come up with an adequate account of the role of experience in cognition

The paper offers an explanation of what reasons for belief are, following Paul Grice in focusing on the roles of reasons in the goal-directed activity of reasoning. Reasons are particularly salient considerations that we use as indicators of the truth of beliefs and candidates for belief. Reasons are distinguished from enabling conditions by being things that we should be able to attend to in the course of our reasoning, and in assessing how well our beliefs are supported. The final section argues that epistemic virtues have a role in enabling us to identify reasons and explores this by reference to the example of being observant.

This volume, derived from the Royal Institute of Philosophy 1992 conference, brings together some of the leading figures in the burgeoning field of cognitive science to explore current and potential advances in the philosophical understanding of mind and cognition. Drawing on work in psychology, computer science and artificial intelligence, linguistics and philosophy, the papers tackle such issues as concept acquisition, blindsight, rationality and related questions as well as contributing to the lively debates about connectionism and neural networks. The collection as a whole reflects the theoretical and methodological dynamism of this interdisciplinary field.

Scepticism is a subject which has preoccupied philosophers for two thousand years. This book presents an historical perspective on scepticism by considering contrasting views, such as those of Sextus Empiricus, Descartes and Hume, on why scepticism is important. With its historical perspective and analysis of contemporary discussions, _Scepticism_ provides a broad focus on the subject, differing from other discussions of the topic in the importance it attaches to scepticism both in Greek thought and in pre-twentieth century views generally.
