Popper and the scepticisms of evolutionary epistemology, or, what were human beings made for?

There is a sort of scepticism or epistemological pessimism that is characterized by appealing to Darwin's theory of evolution. One of the progenitors of naturalized epistemology is EC. R. Popper. The particular twist that he gave to evolutionary epistemology took the form of "thesis Darwinism" according to which an analogue of natural selection. in the form of critical attempts of falsification, allows only the fittest of competing theories to survive. When sniping at the analytical philosophy of his contemporaries and their pretention that the proper function of philosophy is conceptual analysis to assist the progress of science. Popper points out the role of creative imagination and describes science as "revolution in permanence". Some statements of the sceptical naturalist apprehensions are further critically analysed - especially in the works of Michael Ruse, Thomas Nagel, Colin McGinn: Nicholas Rescher and Geoffrey Mill. At the end William Blake is cited in support of Popper's views.
