10. Mackie, Ethics: Inventing Right and Wrong loses to Mill, Utilitarianism by 378–60, loses to Hegel, Philosophy of Right by 194–169 |
Runners-up for the top ten were Ross's The Right and the Good and Williams's collection Moral Luck. The clearest omission from the survey was Murdoch's The Sovereignty of Good, as several correspondents pointed out.
My own views: I was surprised that Mill and Rawls beat Sidgwick, and I was particularly surprised by the weak showing of Stevenson's Ethics and Language, which, while not popular with practitioners of normative ethics, is surely one of the classics of twentieth-century Anglophone philosophy.
