Hilary Putnam

Hilary Putnam (1926-2016) was an American philosopher who made significant contributions to philosophy of mind, language, and mathematics, with important implications for philosophy of religion. His influential "brain in a vat" thought experiment challenged skepticism and external world skepticism, arguments often employed in discussions of divine knowledge and revelation. Putnam's internal realism and later direct realism shaped debates about religious experience and knowledge of God. His critique of logical positivism helped reopen philosophical space for theological discourse. Later in life, Putnam engaged more directly with religious questions, particularly Judaism, arguing for the coherence of religious practice without metaphysical commitments. His work on moral objectivity without moral realism influenced discussions of divine command theory and religious ethics. His pragmatist approach to truth and meaning provided new frameworks for understanding religious language and practice.
