In Aberdeen Reid found himself in the society of persons of more than provincial eminence, destined, indeed, to leave their mark on the thought and literature of Scotland. The Chair of Medicine in his College was occupied by his cousin, Dr. John Gregory, a successful observer of external nature and man. In Marischal College, Thomas Blackwell, the Professor of Greek when Reid was an undergraduate, was now Principal; soon followed by George Campbell, who became the philosophical theologian of the Church of Scotland, by his criticism of Hume’s reasoning about miracles, and a master in literary, biblical, and ecclesiastical criticism,—in his _Philosophy of Rhetoric_, his Translation of the Gospels, and his History of the development of the Christian Church. Campbell was nine years younger than Reid, like him an alumnus of Marischal College; he had been minister of Banchory-Ternan for nine years before he was called to Aberdeen. He rivalled Reid himself in analytic power and calm, candid, luminous reasoning. Alexander Gerard, like Reid, a University reformer, and author of essays on ‘Taste’ and on ‘Genius,’ was Professor of Philosophy in Marischal College, and then of Divinity there, and afterwards at King’s. There was William Duncan, too, whose _Logic_ was for a time in vogue in Scottish Universities—a regent in Marischal College when Reid began to teach philosophy at King’s; and Reid’s lifelong friend Stewart was still in the Chair of Mathematics. Perhaps the most widely known Aberdonian when he lived was James Beattie, poet more than philosopher, Professor of Logic and Moral Philosophy in Marischal College, whose essay on ‘Truth’ gave him a name in the intellectual world, while the grace and pathos of the ‘Minstrel’ and the ‘Hermit’ appealed to a wider class, and secured a popular reputation. Aberdeen and its neighbourhood were then the home also of accomplished physicians and naturalists and scholars—Skenes and Ogilvies, Dunbars and Gordons.
