Tychism

Tychism is a thesis proposed by the American philosopher Charles Sanders Peirce that defines absolute chance as a real 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 Heisenberg's uncertainty principle.

Anatomy of a thesis

In his theory of Tychism, Peirce sought to deny the central position of Necessitarianism 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." [Collected Papers, Vol. VI, paragraph 37.] One of the principal arguments of the Necessitarians is that their position is a presupposition of all science. Peirce attacks this idea asserting: "To 'postulate' a proposition is no more than to hope it is true." [Collected Papers, Vol. VI, paragraph 39.] Thus an avenue is opened up allowing the entry of chance as a fundamental and absolute entity.

Peirce does not, of course, assert that there is "no" law in the universe. On the contrary, he maintains that an absolutely chance world would be a contradiction and thus impossible.Complete lack of order is itself a sort of order. The position he advocates is rather that there are in the universe both regularities and irregularities.

To explain the presence of such a universal "law" Peirce proposes a "cosmological theory of evolution" in which law develops out of chance. The hypothesis that "out of irregularity, regularity constantly evolves" seemed to him to have decided advantages not the least being its explanation of "why laws are not precisely or always obeyed, for what is still in a process of evolution can not be supposed to be absolutely fixed." [Hamblin, pg. 380.]

Underpinnings

Attempting to provide an explanation of some of the more general observable traits of the universe, Peirce formulates four reasons in support of his hypothesis:
# Growth and increasing complexity
# Variety and diversity
# Regularity (laws of nature)
# Mind/consciousness/feeling [Reynolds, pg. 13.] He then asks us to consider how these features could possibly be explained by a strictly determined, mechanistic theory of the way of all things.

Evolution

Peirce very pointedly observed that all the scientifically viable theories of evolution are based on tychistic formulations.

He dismisses Spencerian evolution as fundamentally flawed because of its foundation on mechanical principles. Turning to Darwin he points out that the fundamental driver of his theory is accidental variation, noting that "Darwinian evolution is evolution by the operation of chance, and the destruction of bad results." Even the catastrophism of Clarence King and others, which postulates an acceleration in evolutionary change via sudden environmental dislocations, naturally falls under the rubric of Tychism.

This evolutionary aspect of Tychism compels Peirce to expand Darwin's view to a cosmological level, sending its operations back to the origin of the universe under the regulative principle of his synechism.
