Hilary Putnam on Thinking and Normativity
Realism and Reason (Cambridge University Press: 1985), p. 246.
Why should we expend our mental energy in convincing ourselves that we aren't thinkers, that our thoughts aren't really about anything, noumenal or phenomenal, that there is no sense in which any thought is right or wrong (including the thought that no thought is right or wrong) beyond being the verdict of the moment, and so on? This is a self-refuting enterprise if there ever was one! Let us recognize that one of our fundamental self-conceptualizations ... is that we are thinkers, and that as thinkers we are committed to there being some kind of truth, some kind of correctness which is substantial.... That means that there is no eliminating the normative.
