Though he had as little booklearning as the most stupid ploughboys of England, it would have been a great error to put him in the same intellectual rank with such ploughboys. It is indeed only by reading that men can become profoundly acquainted with any science. But the arts of poetry and rhetoric may be carried near to absolute perfection, and may exercise a mighty influence on the public mind, in an age in which books are wholly or almost wholly unknown. The first great painter of life and manners has described, with a vivacity which makes it impossible to doubt that he was copying from nature, the effect produced by eloquence and song on audiences ignorant of the alphabet. It is probable that, in the Highland councils, men who would not have been qualified for the duty of parish clerks sometimes argued questions of peace and war, of tribute and homage, with ability worthy of Halifax and Caermarthen, and that, at the Highland banquets, minstrels who did not know their letters sometimes poured forth rhapsodies in which a discerning critic might have found passages which would have reminded him of the tenderness of Otway or of the vigour of Dryden. There was therefore even then evidence sufficient to justify the belief that no natural inferiority had kept the Celt far behind the Saxon. It might safely have been predicted that, if ever an efficient police should make it impossible for the Highlander to avenge his wrongs by violence and to supply his wants by rapine, if ever his faculties should be developed by the civilising influence of the Protestant religion and of the English language, if ever he should transfer to his country and to her lawful magistrates the affection and respect with which he had been taught to regard his own petty community and his own petty prince, the kingdom would obtain an immense accession of strength for all the purposes both of peace and of war.
