Tychism \Ty"chism\, n. [Gr. ty`chh fortune, chance + -ism.] Any theory which conceives chance as an objective reality; esp., a theory of evolution which considers that variation may be purely fortuitous.


Tychism ( "chance") is a thesis proposed by the American philosopher Charles Sanders Peirce that holds that absolute chance, or indeterminism, is a real factor operative in the universe. This doctrine forms a central part of Peirce's comprehensive evolutionary cosmology. It may be considered both the direct opposite of Einstein's oft quoted dictum that: " God does not play dice with the universe" and an early philosophical anticipation of Werner Heisenberg's uncertainty principle.
