Abstract

Are our beliefs mostly true? Donald Davidson has proposed some very interesting arguments in favor of his "extended claim" that most our beliefs must be true. The main aim of this paper is to show that Davidson's arguments are not convincing. The most well known of his arguments is the argument of the "omniscient interpreter". The conceivability of a totally ignorant interpreter, however, shows that this argument fails. Davidson offers two more arguments for his extended claim: one of them based on his holism of the propositional attitudes, the other one based on his externalism of language and thought. Both arguments, however, do not sufficiently support the extended claim. Hence, it must remain open at least whether we live in one of the best possible epistemic worlds.
