Joseph Butler (May 18, 1692 O.S. - June 16, 1752) was an English bishop, theologian, apologist, and philosopher. He is known, among other things, for his critique of Thomas Hobbes's egoism and John Locke's theory of personal identity. During his life and after his death, Butler influenced many philosophers, including David Hume, Thomas Reid, and Adam Smith. He is most famous for his Fifteen Sermons Preached at the Rolls Chapel (1726) and Analogy of Religion, Natural and Revealed (1736).
