Selection theory requires multiple, distinct, simultaneously-actualized states. In cognition, each thought or cognitive state changes the "selection pressure" against which the next is evaluated; they are not simultaneously selected amongst. Creative thought is more a matter of honing in on a vague idea through redescribing successive iterations of it from different real or imagined perspectives; in other words, actualizing potential through exposure to different contexts. It has been proven that the mathematical description of contextual change of state introduces a non-Kolmogorovian probability distribution, and a classical formalism such as selection theory cannot be used. This paper argues that creative thought evolves not through a Darwinian process, but a process of context-driven actualization of potential. (Contains 4 footnotes.)
