1908 – 2000
Willard Van Orman Quine (1908–2000) was an American philosopher and logician widely regarded as one of the most influential analytic philosophers of the twentieth century. His work systematically challenged foundationalist epistemology and the analytic/synthetic distinction, redirecting philosophy toward naturalism and the continuity of science and philosophy. His contributions span logic, set theory, philosophy of language, and ontology.
