Bishop Joseph Butler is a well-known religious philosopher of the eighteenth century. He is still read and discussed among contemporary philosophers, especially for arguments against some major figures in the history of philosophy, such as Thomas Hobbes and John Locke. In his Fifteen Sermons Preached at the Rolls Chapel (1729), Butler argues against Hobbes’s egoism, and in the Analogy of Religion (1736), he argues against Locke’s memory-based theory of personal identity.

Overall, Butler’s philosophy is largely defensive. His general strategy is to accept the received systems of morality and religion and, then, defend them against those who think that such systems can be refuted or disregarded. Butler ultimately attempts to naturalize morality and religion, though not in an overly reductive way, by showing that they are essential components of nature and common life. He argues that nature is a moral system to which humans are adapted via conscience. Thus, in denying morality, Butler takes his opponents to be denying our very nature, which is untenable. Given this conception of nature as a moral system and certain proofs of God’s existence, Butler is then in a position to defend religion by addressing objections to it, such as the problem of evil.

This article provides an overview of Butler’s life, works, and influence with special attention paid to his writings on religion and ethics. The totality of his work addresses the questions: Why be moral? Why be religious? Which morality? Which religion? In attempting to answer such questions, Butler develops a philosophy that possesses a unity often neglected by those who read him selectively. The philosophy that develops is one according to which religion and morality are grounded in the natural world order.
