Abstract
A constructive interpretation is given of Paul Feyerabend's philosophy'of science as being not really irrationalistic but only pseudo-irrationalistic, and as being in need of an account of how science is distinct and how related to other activities. To this end, Benedetto Croce's philosophy is considered, constructively criticized, and shown to be unexpectedly promising; its valuable element is not the instrumentalistic theory of science officially present in his Logica but the distinctionism-relationism that he practiced everywhere and especially in his literary criticism. A summary is then given of results obtained or expected from an investigation of Galileo Galilei's Dialogue on the Two Chief World Systems carried out in the spirit of such a modified Crocean approach.
