Justifying critical pluralism as a philosophy of complexity

By assuming that the Universe is best described as a cellular automaton, and by making use of some of the results from the field of computational mechanics, this paper discusses the extension of the notion of existence from a simple binary opposition to that of a continuum. It is argued that none of the traditional objects of science, or any objects from any discipline formal or not, can be said to be real in any absolute sense though a substantial realism may be associated with them. By problematising existence it is proposed that an evolutionary philosophy referred to as critical pluralism is more sensitive to the demands of complexity than contemporary scientific thought. Though many of the conclusions reported herein are not original, the fact that they can be ‘proved’ in a scientific sense, and explored scientifically, is certainly of interest and is an interpretation of complexity theory that has received little attention.
