ABSTRACT The relationship of Hume’s thought with Calvinism is complex and difficult to pin down. He is mordantly critical of the theology and morality of the “predestinarian doctors” and out of tune with the rational theology of Francis Hutcheson and even with that of his friends, Enlightened Ministers of the Church of Scotland such as Hugh Blair and Robert Wallace. Nevertheless, a few of his key philosophical tenets are almost indistinguishable from the main ideas advanced in Calvin’s Institutes of the Christian Religion. I argue that for this reason Hume’s philosophy of religion is an Enlightened form of Calvinism. These strongly parallel doctrines must be considered in any evenhanded interpretation of the chief principles of Hume’s philosophy of religion that are set forth in “Of Miracles,” in The Natural History of Religion, and in the Dialogues Concerning Natural Religion. This approach also opens a thoughtful understanding of the main conclusions of the Dialogues.
