Joseph Butler was an English Anglican bishop, theologian, apologist, and philosopher, born in Wantage in the English county of Berkshire. He is known for critiques of Deism, Thomas Hobbes's egoism, and John Locke's theory of personal identity. The many philosophers and religious thinkers Butler influenced included David Hume, Thomas Reid, Adam Smith, Henry Sidgwick, John Henry Newman, and C. D. Broad, and is widely seen as "one of the pre-eminent English moralists." He played a major, if underestimated role in developing 18th-century economic discourse, influencing the Dean of Gloucester and political economist Josiah Tucker.
