This is a new online archive of works by the philosopher Bernard Williams. I know Williams for two major areas of work: first, his work on ethics (and especially the concepts of utilitarianism and of moral luck), and second, his razor-sharp insightful work on the philosophy of René Descartes. Unfortunately the book links just redirect you to Amazon (where research goes to die). Similarly, many of the links go to paywalls (what publishing has done to philosophy is an absolute sdhame). But there are enough links to open sources to give you a sense.
