passage he inserted in the new edition of his Theory of Moral Sentiments, published immediately before his death in 1790—­contains a high tribute to the gifts and character of that famous man.  In this passage Smith seeks to illustrate a favourite proposition of his, that men of science are much less sensitive to public criticism and much more indifferent to unpopularity or neglect than either poets or painters, because the excellence of their work admits of easy and satisfactory demonstration, whereas the excellence of the poet’s work or the painter’s depends on a judgment of taste which is more uncertain; and he points to Robert Simson as a signal example of the truth of that proposition.  “Mathematicians,” he says, “who may have the most perfect assurance of the truth and of the importance of their discoveries, are frequently very indifferent about the reception which they may meet with from the public.  The two greatest mathematicians that I ever have had the honour to be known to, and I believe the two greatest that have lived in my time, Dr. Robert Simson of Glasgow and Dr. Matthew Stewart of Edinburgh, never seemed to feel even the slightest uneasiness from the neglect with which the ignorance of the public received some of their most valuable works."[8] And it ought to be remembered that when Smith wrote thus of Simson he had been long intimate with D’Alembert.

But while Smith improved his Greek under Dunlop, and acquired a distinct ardour for mathematics under the inspiring instructions of Simson, the most powerful and enduring influence he came under at Glasgow was undoubtedly that of Hutcheson—­“the never-to-be-forgotten Hutcheson,” as he styled him half a century later in recalling his obligations to his old College on the occasion of his election to the Rectorship.  No other man, indeed, whether teacher or writer, did so much to awaken Smith’s mind or give a bent to his ideas.  He is sometimes considered a disciple of Hume and sometimes considered a disciple of Quesnay; if he was any man’s disciple, he was Hutcheson’s.  Hutcheson was exactly the stamp of man fitted to stir and mould the thought of the young.  He was, in the first place, one of the most impressive lecturers that ever spoke from an academic chair.  Dugald Stewart, who knew many of his pupils, states that every one of them told of the extraordinary impression his lectures used to make on their hearers.  He was the first professor in Glasgow to give up lecturing in Latin and speak to his audience in their own tongue, and he spoke without notes and with the greatest freedom and animation.  Nor was it only his eloquence, but his ideas themselves were rousing.  Whatever he touched upon, he treated, as we may still perceive from his writings, with a certain freshness and decided originality which must have provoked the dullest to some reflection, and in a bracing spirit of intellectual liberty which it was strength and life for the young mind to breathe.  He was not long in Glasgow, accordingly, till he was
