William P. Alston is Professor of Philosophy Emeritus at Syracuse University. He is the author of several books, including The Reliability of Sense Perception, also from Cornell.

Much in this book deserves agreement and applause; it is argued with care, subtlety, and good sense.(The Journal of Philosophy) Alston's book makes a distinguished contribution to thought about truth, both in its positive proposal and in its sustained criticism of epistemic conceptions.... His book is mandatory reading for anyone with even a slight interest in truth.(The Philosophical Review) From the standpoint of both general readers and professionals in the field this may be one of the best philosophical books to come along in some time.... The depth, the scope, and the clarity of Alston's analysis is matched only by that of the great philosophers with whom he contends. Highest recommendation for all collections.(Choice) This excellent, ludidly written study contains many valuable insights.(Erkenntnis)
