Terminological infelicities have a way of breeding conceptual confusion.

The dominant metaphor of conceptual relativism, that of differing points of view, seems to betray an underlying paradox. Differentpoints of view make sense, but only if there is a common co-ordinate system on which to plot them yet the existence of a common system belies the claim of dramatic incomparability.

Nothing in the world, no object or event, would be true or false if there were not thinking creatures.

There is no such thing as a language, not if a language is anything like what many philosophers and linguists have supposed. Thereis therefore no such thing to be learned, mastered, or born with. We must give up the idea of a clearly defined shared structure which language-users acquire and then apply to cases.

If we cannot find a way to interpret the utterances and other behaviour of a creature as revealing a set of beliefs largely consistent and true by our standards, we have no reason to count that creature as rational, as having beliefs, or as saying anything.

Even if someone knew the entire physical history of the world, and every mental event were identical with a physical, it would notfollow that he could predict or explain a single mental event (so described, of course).

Mental events such as perceivings, rememberings, decisions, and actions resist capture in the net of physical theory.
