Because language is a “public” Mirror of Nature, as thought is a “private” one, it seems that we should be able to reformulate a great many Cartesian and Kantian questions and answers in linguistic terms, and thereby rehabilitate a lot of standard philosophical issues (e.g., the choice between idealism and realism). I devote chapter six to various efforts at such rehabilitation, and argue that semantics should be kept as pure of epistemology as should psychology.
