Theory vs Anti-Theory

Bernard Williams influentially attacked ethical theory. This paper assesses arguments for the ‘anti-theory’ position in ethics, including mainly arguments put forward by Williams but also arguments put forward by others. The paper begins by discussing what is supposed to be theory in ethics and what ethical intuitions are taken to be by those involved in the theory versus anti-theory debate. Then the paper responds to the objections that ethical theory is mistaken to prize principles, mistaken to prize rationalism, mistaken to presume or prize foundational unity, mistaken to presume morality is deeply impartial, mistaken to presume to tell agents how to deliberate, mistaken to presume or prize ethical codifiability, mistaken to presume value commensurability, and mistaken to eliminate ethical dilemmas.
