Bernard Williams

Analytic · Europe · 1929 to 2003

British philosopher who doubted that moral theories can make room for the personal commitments, and the luck, that shape real lives.

What it is

Bernard Williams (1929 to 2003) was a British philosopher widely regarded as the most important British moral philosopher of his time. He taught at Cambridge and elsewhere, and was a leading influence on philosophical ethics in the second half of the twentieth century.

He rejected the idea that ethics can be turned into a moral theory, as Kantianism and above all utilitarianism claim. Our ethical life, he argued, is too untidy to be captured by any system. He also wrote on personal identity, equality, the emotions and the history of philosophy.

The main ideas

  • Against moral theory. He doubted that morality can be reduced to a single principle or system, and held that such theories misdescribe how ethical life actually goes.
  • Integrity. A person's deepest commitments are part of who they are, and a morality that demands they set these aside whenever the numbers favour it threatens their integrity.
  • Moral luck. How well a life goes morally can depend on factors outside a person's control, which challenges the idea that moral worth is wholly up to us.
  • Internal reasons. A person has a reason to act only if it connects with something in their existing motives, a view about the link between reasons and motivation.
  • Thick concepts. Concepts such as cruelty or courage mix fact and evaluation and are part of real ethical thought.

What it looks like in practice

Picture someone who is told that on the numbers they ought to give up a project they care about deeply in favour of a slightly larger benefit to strangers. Williams would say that treating that person's commitments as just one more input to be weighed is a kind of alienation from their own life. This is an illustration of the idea, not a quotation.

Books and moments

  • Ethics and the Limits of Philosophy (1985) is his main work on moral theory and ethical life.
  • Shame and Necessity is a study of Greek ethical thought.
  • Truth and Truthfulness is his late book on the value of truth.

Questions and criticism

  • Is a moral theory impossible? Defenders of utilitarianism and Kantianism reply that a good theory can respect the complexity he points to.
  • Is moral luck compatible with responsibility? If luck shapes moral standing, it is asked how far people can be held responsible.
  • Do all reasons depend on our motives? His view of internal reasons has been defended and strongly criticised.

Close neighbours

He argued with utilitarians and Kantians, and he drew on Nietzsche and the Greeks. The pages on Mill, Kant and Nietzsche show the positions he engaged.
