The Taming of the True defends and develops global semantic anti-realism. Neil Tennant argues compellingly that every truth is knowable, and that manifestationism in the theory of meaning entails logical reform. He extends semantic anti-realism to empirical discourse, developing new accounts of the analytic/synthetic distinction, cognitive significance and constructive falsifiability. The book has important consequences for the philosophy of mathematics and logic, the theory of meaning, metaphysics, and epistemology.
