Robert Hardie's parents were William Purves Hardie, a clothier, and Agnes Ross. Robert was educated at Circus Place School, Edinburgh. He then went to the University of Oxford and was awarded a B.A. in 1888. Hardie then returned to Edinburgh where he was appointed as an Assistant in Logic and Metaphysics at the University in 1889.
Hardie remained an assistant until 1892 when he was promoted to Lecturer in Logic and Metaphysics. Remaining at Edinburgh University he was again promoted, this time to Reader in Ancient Philosophy in 1920. He remained in this post until he retired in 1932.
The Edinburgh Mathematical Society was founded in 1883 and Hardie joined the Society at its inaugural meeting in February of that year. At this time he gave his address as 4 Scotland Street, Edinburgh. He appears to have left the Edinburgh Mathematical Society in 1930 but joined again two years later after he retired. On Friday 9 March 1923 a discussion on the teaching of elementary geometry was opened by Mr A J Tressland, M.A., F.R.S.E., of the Edinburgh Academy, who advocated the adoption of the sequence in geometrical teaching contained in the schedule recently issued by a special committee of the Assistant-Masters' Association. hardie took part in the subsequent discussion.
