The trouble with religious morality comes not from morality’s being inescapably pure, but from religion’s being incurably unintelligible.

Sir Bernard Williams was a British moral philosopher, and one of the most influential of the latter half of the twentieth century.
He didn’t propose any systematic philosophical theory—indeed, was suspicious of any such attempt. Rather, he tried to address the question of how to live, focusing on the complexity of everyday life. The study of ethics, he argued, should be vital and compelling. He wanted to find an approach that was accountable to psychology, history, politics, and culture.
