Tychism

Tychism () 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 Albert 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.

==The thesis== In his theory of tychism, Peirce sought to deny the central position of the doctrine of necessity which maintains that "the state of things existing at any time, together with certain immutable laws, completely determine the state of things at every other time." One of the principal arguments of the necessitarians is that their position involves a presupposition of all science. Peirce attacks this idea asserting: "To 'postulate' a proposition is no more than to hope it is true." Thus an avenue is opened up allowing the entry of chance as a fundamental and absolute entity.
