Naturalism And Evolution

Decent Essays

Popularizing the claim that naturalism and evolution are mutual self-defeaters, Alvin Plantinga argues, in Evolutionary Argument Against Naturalism (1993), that given unguided evolution, our beliefs have no intrinsic relation to the truth.

Drawing on previous arguments made by C.C Lewis and Arthur Balfour, Plantinga claims that if humans are the product of undirected processes, then we cannot reasonably rely on our cognitive faculties. In fact, it’s just “as likely, … that we live in a sort of dream world as that we actually know something about ourselves and our world.”

Thus, if we cannot rely on our beliefs, then we cannot rely on our belief in naturalism and, ahem, evolution. And therefore naturalism is defeated.

But, inserting a supernatural element (God) as a key fact is a circular argument. Viz. if God exists, naturalism is not true, so there’s no use invoking God as evidence that naturalism is untrue. (Prove God exists first!).

Further, the Philosopher William Ramsay has observed how human faculties are, in fact, slightly unreliable – look at our impressive array of cognitive biases - and further posits that evolution and naturalism explain this better than theism. In fact, the well-established foibles in our thinking pose a considerable challenge to Plantinga’s suggestion that we are the perfect perceivers of truth one would expect as the product of an omnipotent Creator.

Plantinga’s argument trades upon the philosophical knowledge-problem: the difficulty in providing a neat solution to the foundation of knowledge: how do we know we can rely on our beliefs? But this philosophical problem is not specific to either evolution of naturalism: the challenge pertains to all of our beliefs.

In fact, our evolution by natural selection justifies a moderate level of trust in our cognitive faculties. The brain size of human species has increased from 400cc to 1350cc over several millions of years. In this time archaic humans developed more sophisticated stone tools, harnessed fire, developed language, and began to use symbolic thought. Natural selection seems to have been effective in providing
