ABSTRACT
As I explain in the essays which follow, there are two main approaches that people have taken in trying to bring evolutionary thinking to bear on philosophical problems of knowledge and epistemology. The first is to argue by analogy from the main evolutionary mechanism of natural selection to the supposed way in which knowledge, particularly scientific knowledge, arises and develops. The second is to argue literally, from the way in which natural selection has shaped us humans as thinking beings to the kind of knowledge claims that we would make.
