 According to Williams, however, act-utilitarianism in fact demands a different kind of sacrifice from George. It demands that he act without integrity, abandoning or ignoring a longstanding, identity-conferring commitment to pacifism simply because maximum general well-being is to be found elsewhere. This is just one, particularly acute, example of the tendency of impartial utilitarian deliberation to run roughshod over identity-conferring commitments, treating them as no more than one source of utility among others. In general, Williams concludes, identity-conferring commitments cannot play the kind of role in act-utilitarian moral deliberation that is required for an agent to act with integrity, that is, for an agent to act with genuine conviction in matters of grave, identity-determining importance to them.
