 Williams worked in Britain until 1987, when he left for Berkeley in protest at the impact of the Thatcher government’s policies on British universities. These policies had not stopped him from publishing, in 1985, the book that offers the most unified and sustained presentation of what Williams had to say about ethics and human life: Ethics and the Limits of Philosophy. On his return to Britain in 1990 (incidentally the year of Mrs. Thatcher’s resignation) he succeeded his old tutor Richard Hare as White’s Professor of Moral Philosophy at Oxford. While in the Oxford chair he produced Shame and Necessity (1993), a major study of Greek ethics which aims to distinguish what we think about ethics “from what we think that we think” (1993: 91): Williams’ thesis is that our deepest convictions are often more like classical Greek ethical thought, and less like the post-Enlightenment “morality system”, as Williams came to call it, than most of us have yet realised. (More about the morality system in sections 2 and 3.)
