He was the son of Matthew Stewart, who for 25 years was professor of mathematics at Edinburgh University, and there young Dugald studied from 1765 to 1769, devoting himself to mathematics and philosophy. In the latter sub ject his teacher was Adam Ferguson. In 1771 Stewart went to Glasgow, partly to prepare him self as a candidate for one of the Snell scholar ships at Oxford, and partly to attend the lec tures of Thomas Reid, who came to exercise a profound influence on the young student.
