Darwin to T. H. Huxley, Down, December 2, 1860, Lit'e and.Letters,2:147. Darwin had both the good fortune and the misfortune to begin his scien- tific career at precisely that moment in history when philosophy of science came into its own in England. Of course, philosophers from plato and Aristotle had always written on epistemology and, after the scientific revolu- tion, they were presented with the added advantage and obligation of recori- ciling their philosophies with the current state of science. some of these philosophers were also themselves scientists. But the works of Descartes, Locke, Hume, Berkeley, Leibnitz, and Kant do not exhibit the same concern with the accomplishments of science and the nature of the .,scientific method" which has come to characterize philosophy of science.l i.
