Our ancestors believed in many things which did not exist—gods, witches, the luminiferous ether, phlogiston, reincarnated souls, sense-data, conceptual analysis, and the like. But they had no better ways of coping with the irradiations beating down upon their sense organs. So they were justified in making assertions which did not bear those desirable relations to things in the world—relations like naming and truth—which we like to think are sustained by our own assertions. This fact brings out the difference between the (...) results of rational, sincere and industrious inquiry on the one hand, and truth on the other. Our ancestors had all the former virtues, but somehow these did not suffice to get them in touch with reality. Since we can no longer dismiss them as blinded by prejudice, passion and superstition, we would like some philosophical way of explaining our superiority to them. (shrink)

Donald Davidson has argued that attention to the necessarily public character of language shows that we cannot be massively mistaken about the world around us, and that consequently skeptical doubts about empirical knowledge are misplaced. The arguments Davidson advances rely on taking as the fundamental methodological standpoint for investigating meaning and related concepts the standpoint of the interpreter of another speaker, on the grounds that it is from the interpreter’s standpoint that we discover what constraints are placed on meaning by (...) the public character of language. In this paper, I argue that although Davidson’s arguments reveal important conceptual connections between meaning and belief on the one hand, and truth and interpretation on the other, they do not show that it is impossible that we are massively mistaken about the external world.
