Abstract

A number of thorny issues, such as the nature of time, free will, the clash of the manifest image and the scientific image, the possibility of a naturalistic foundation of morality, and perhaps even the possibility of accounting for consciousness in naturalistic terms, seem to be plagued by the conceptual confusion nourished by a single fallacy: the old fisherman's mistake. This is the mistake that consists in disregarding the fact that knowledge is not just learning new facts about old concepts. Knowledge is often to realise the inadequacy and misleading character of some of our old concepts, and the intuitions that ground them.
