1926 – 2016
Hilary Putnam (1926-2016) was an influential American philosopher who made major contributions to philosophy of mind, philosophy of language, philosophy of mathematics, and philosophy of science. Known for his intellectual honesty in repeatedly revising his own positions, he developed functionalism, the causal theory of reference, and internal realism, shaping analytic philosophy for over half a century.
