'''Clarence Irving Lewis''' (April 12, 1883 – February 3, 1964) was an American academic [[philosopher]]. He is considered the progenitor of modern [[modal logic]] and the founder of [[conceptual pragmatism]].<ref>[[Sandra B. Rosenthal]], ''C. I. Lewis in Focus: The Pulse of Pragmatism'', Indiana University Press, 2007, p. 28.</ref> First a noted [[logic]]ian, 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 [[Mathematical logic#Symbolic logic|symbolic logic]] and on the philosophic concepts of [[knowledge]] and [[Value (ethics)|value]]."<ref>[https://www.nytimes.com/1964/02/04/clarence-i-lewis-philosopher-dies.html?_r=0 C.I. Lewis obituary, New York Times, February 4, 1964]</ref> He coined the term "[[Qualia]]" as used in philosophy, linguistics, and cognitive sciences.<ref name="mind">Lewis, Clarence Irving (1929).
