John Stevenson came from the Merse region in the Scottish Borders. He studied the arts course at Edinburgh University, 1710–14, and the divinity course, 1715–21. He attended history lectures in 1721–3, but not as a paying student. Whether he was licensed as a minister has not been established. After a period as tutor in a private family, he was appointed Professor of Logic at Edinburgh in 1730 and held the post until his retirement in 1774, when he was made LL.D.
