John Bruce, of the Bruce family of Earlshall, was born in Scotland and died on 16 April 1826 at Nuthill in Fifeshire. He studied at Edinburgh University (1761–7), where he was one of the founders of the Speculative Society (1764). He was appointed joint Professor of Logic and Metaphysics at Edinburgh in 1774, succeeding his teacher Stevenson in the chair in 1775 and resigning the post in 1792. He then became a historical researcher and went into political service, and eventually into politics, serving as an MP from 1809 to 1814. As Professor of Logic, he also deputized for a year for Adam Ferguson in the moral philosophy class.
