Darwin's "strange inversion of reasoning" and Turing's equally revolutionary inversion were aspects of a single discovery: competence without comprehension. Comprehension, far from being a Godlike talent from which all design must flow, is an emergent effect of systems of uncomprehending competence: natural selection on the one hand, and mindless computation on the other. These twin ideas have been proven beyond a reasonable doubt, but they still provoke dismay and disbelief in some quarters, which I have tried to dispel in this chapter. Creationists are not going to find commented code in the inner workings of organisms, and Cartesians are not going to find an immaterial res cogitans "where all the understanding happens".
