The philosopher David Hume was born in Edinburgh, Scotland on April 26, 1711. Known for his re-thinking of causation, morality, and religion, Hume has left a lasting mark on history. James Madison, the ‘father’ of the U.S. Constitution, drew heavily on Hume’s writing, especially his ‘Idea of Perfect Commonwealth, ‘ which combated the belief at the time that a large country could not sustain a republican form of government. Hume’s writing also influenced Adam Smith’s Wealth of Nations and the philosophy of Immanuel Kant. The Historical Dictionary of Hume’s Philosophy is the only Hume dictionary in existence. The book provides a substantial account of David Hume’s life and the times in which he lived, and it provides an overview of his philosophical doctrines. This is done through a chronology, an introductory essay, a bibliography, and over a hundred cross-referenced dictionary entries covering key terms, as well as brief discussions of Hume’s major works and of some of his most important predecessors, contemporaries, and successors.
