His studies took a new turn at Oxford; he laid aside the mathematics for which he showed a liking at Glasgow, and gave his strength to the ancient Latin and Greek classics, possibly for no better reason than that he could get nobody at Oxford to take the trouble of teaching him the former, and that the Balliol library furnished him with the means of cultivating the latter by himself.  He did so, moreover, to some purpose, for all through life he showed a knowledge of Greek and Latin literature not only uncommonly extensive but uncommonly exact.  Dalzel, the professor of Greek at Edinburgh, was one of Smith’s most intimate friends during those latter years of his life when he was generally found with one of the classical authors before him, in conformity with his theory that the best amusement of age was to renew acquaintance with the writers who were the delight of one’s youth; and Dalzel used always to speak to Dugald Stewart with the greatest admiration of the readiness and accuracy with which Smith remembered the works of the Greek authors, and even of the mastery he exhibited over the niceties of Greek grammar.[12] This knowledge must of course have been acquired at Oxford.  Smith had read the Italian poets greatly too, and could quote them easily; and he paid special care to the French classics on account of their style, spending much time indeed, we are told, in trying to improve his own style by translating their writings into English.

There was only one fruit in the garden of which he might not freely eat, and that was the productions of modern rationalism.  A story has come down which, though not mentioned by Dugald Stewart, is stated by M’Culloch to rest on the best authority, and by Dr. Strang of Glasgow to have been often told by Smith himself, to the effect that he was one day detected reading Hume’s Treatise of Human Nature—­probably the very copy presented him by the author at the apparent suggestion of Hutcheson—­and was punished by a severe reprimand and the confiscation of the evil book.  It is at least entirely consistent with all we know of the spirit of darkness then ruling in Oxford that it should be considered an offence of peculiar aggravation for a student to read a great work of modern thought which had been actually placed in his hands by his professor at Glasgow, and the only wonder is that Smith escaped so lightly, for but a few years before three students were expelled from Oxford for coquetting with Deism, and a fourth, of whom better hopes seem to have been formed, had his degree deferred for two years, and was required in the interval to translate into Latin as a reformatory exercise the whole of Leslie’s Short and Easy Method with the Deists.[13]
