In my essay, I will argue that evolution does not undermine naturalism. This is because Alvin Plantinga’s evolutionary argument against naturalism rests on a false and unmotivated premise and is thus invalid. My argument consists of two parts: In the expository part, I outline Plantinga’s evolutionary argument against naturalism in considerable detail (section 2). In the argumentative part, I firstly pose William Ramsey’s challenge to Plantinga’s probabilistic claim that the reliability of human cognitive faculties is low and critically examine Plantinga’s (...) response in order to reinforce it (section 3). Secondly, I attack Plantinga’s understanding of human evolution, which motivates his cognitive skepticism, as being unduly narrow (section 4). (shrink)
