description: "Clarence Irving Lewis was an American academic philosopher. He is considered the progenitor of modern modal logic and the founder of conceptual pragmatism. First a noted logician, he later branched into epistemology, and during the last 20 years of his life, he wrote much on ethics. The New York Times memorialized him as \"a leading authority on symbolic logic and on the philosophic concepts of knowledge and value.\" He coined the term \"Qualia\" as used in philosophy, linguistics, and cognitive sciences."
