Evolutionary Naturalism

Nature volume 110, page 631 (11 November 1922) | Download Citation



THE author of this book is one of the “critical” realists. The difference between a neo-realist and a critical realist would seem to be that the former regards the datum of perception as identical with the object of knowledge, while the latter distinguishes between them. The neo-realist says that we know the physical existence in perceiving it, the critical realist says we know the existence of the physical thing but what we perceive is its essence. Objects exist, but only their content and not their existence is perceived. The special theory which Prof. Sellars names evolutionary naturalism is based on this distinction. Its two great enemies, we are told, are Platonism and Kantianism, both of which are supernaturalistic. The theory is worked out in laborious detail and applied to the different problems of philosophy.
