“It may at first surprise those who follow the course of later Greek thought that the two great systems of Plato and Aristotle had comparatively little influence on the generations immediately following their inception, and that it was not till after several centuries that the development and partial fusion of the two took place. Nothing however, is more striking in the history of thought than the immediate transience, and the final permanence, of genial philosophical ideas.”
