Scottish philosopher, and chief of the Scottish school, born in Kincardineshire, and bred for the Scotch Church, in which he held office as a clergyman for a time; was roused to philosophical speculation by the appearance in 1730 of David Hume's "Treatise on Human Nature," and became professor of Philosophy in Aberdeen in 1752, and in Glasgow in 1763, where the year after he published his "Inquiry into the Human Mind," which was followed in course of time by his "Philosophy of the Intellectual and Active Powers"; his philosophy was a protest against the scepticism of Hume, founded on the idealism of Berkeley, by appeal to the "common-sense" of mankind, which admits of nothing intermediate between the perceptions of the mind and the reality of things (1710-1796).
