Thoughts and other mental states are defined by their role in a functional system. Since it is easier to determine when we have knowledge than when reasoning has occurred, Gilbert Harman attempts to answer the latter question by seeing what assumptions about reasoning would best account for when we have knowledge and when not. He describes induction as inference to the best explanation, or more precisely as a modification of beliefs that seeks to minimize change and maximize explanatory coherence. Originally (...) published in 1973. 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.

Change in View offers an entirely original approach to the philosophical study of reasoning by identifying principles of reasoning with principles for revising one's beliefs and intentions and not with principles of logic. This crucial observation leads to a number of important and interesting consequences that impinge on psychology and artificial intelligence as well as on various branches of philosophy, from epistemology to ethics and action theory. Gilbert Harman is Professor of Philosophy at Princeton University. A Bradford Book.

In this paper I examine what I will call "the standard account" of intrinsic value as it appears in recent textbooks written by John Hospers, William Frankena, and Richard B. Brandt. I argue: (a) it is not clear whether a theory of intrinsic value can be developed along the lines of the standard account; (b) if one is to develop such a theory, one will need to introduce a notion of "basic intrinsic value" in addition to the notion of "intrinsic (...) value"; and (c) several different theories of intrinsic value may account for the same judgments concerning desirability, and it will be arbitrary to choose one of these theories over another.

An attempt to analyse what it is for belief to be based on reasons becomes involved with questions about the goodness of reasons and the gettier examples. intuitions about knowledge and the "gettier effect" can be used to decide when reasoning has occurred and what reasoning there has been. explanation by reasons is not deterministic.
