On a New List of Categories

Charles Sanders Peirce was an American philosopher, logician, mathematician, and scientist who was known as "the father of pragmatism". 


On May 14, 1867, the 27-year-old Charles Sanders Peirce presented a work entitled "On a New List of Categories" to the American Academy of Arts and Sciences. Among other things, this work outlined a theory of predication involving three universal categories that Peirce continued to apply in philosophy and elsewhere for the rest of his life. 


For Pierce’s original concepts Webster's Biographical Dictionary said in 1943 that Peirce was "now regarded as the most original thinker and greatest logician of his time."
