Complexity in 140 words

Recent developments in complexity theory with particular emphasis on "emergence" may provide a bridge between science and other approaches.  Emergence in systems of agents interacting by non linear rules allows one both to take a reductionist position and believe in novelty.  Selection rules or pruning algorithms allow the generation of upper hierarchical levels from the combinatoric explosion generated by complex non linear systems interacting by reductionist laws.  This selection is a new feature of modern computer driven science and tends to reify "the whole being different from the sum of the parts."  To the computer theorist with a theological bent this is how the word (laws of nature, divine immanence) becomes flesh.  This view opens up a dialogue between science and religion at a new level that avoids many of the difficulties of past confrontations although epistemological differences still persist.
