Abstract

Richard Foley's theory of epistemic rationality specifies what a cognitive agent should believe, whose epistemic goal is now to believe truths and not to believe falsehoods. As the emphasis upon 'now' demonstrates, this is a synchronic, not a diachronic, theory. Foley acknowledges the importance of long-term intellectual goals in human lives--particularly in their practical aspect, and in scientific practice. But such goals are beyond the scope of a purely epistemic theory of rationality.
