Knowledge and Infallibility

Abstract

One of the recurring themes in the history of speculation about knowledge is the notion that knowledge cannot be mistaken. At first sight this would appear to be platitudinously true. There would, I expect, be general agreement that there cannot be two varieties of knowledge, namely true knowledge and false knowledge, as there are two varieties of belief, namely true belief and false belief. If, therefore, the dictum ‘knowledge cannot be mistaken’ implies no more than the fact that the disjunction ‘either true or false’ does not apply to knowledge, there is no problem: if someone believes that a given proposition is true, the proposition may be true and may be false; if, however, someone knows that a given proposition is true, then the proposition is true. In this sense, knowledge and truth are inextricably linked in a way in which belief and truth are not.
