In his Critique of Pure Reason, Kant argues that we can know what the existing world must be like, but only if it is considered idealistically, which for Kant means relative to our senses.Analytic philosophy, however, tends to be skeptical that the world of our senses must be like anything at all. This book defends Kant in terms of techniques that belong to analytic philosophy itself, in particular, to its philosophy of language. In addition, the book first abstracts and then departs from its interpretation of Kant to provide a realistic account of the idea of what the sensible world must be like.
