He was not long in Glasgow, accordingly, till he was bitterly attacked by the older generation outside the walls of the College as a "new light" fraught with dangers to all accepted beliefs, and at the same time worshipped like an idol by the younger generation inside the walls, who were thankful for the light he brought them, and had no quarrel with it for being new. His immediate predecessor in that chair, Professor Gershom Carmichael, the reputed father of the Scottish Philosophy, was still a Puritan of the Puritans, wrapt in a gloomy Calvinism, and desponding after signs that would never come. But Hutcheson belonged to a new era, which had turned to the light of nature for guidance, and had discovered by it the good and benevolent Deity of the eighteenth century, who lived only for human welfare, and whose will was not to be known from mysterious signs and providences, but from a broad consideration of the greater good of mankind--"the greatest happiness of the greatest number." Hutcheson was the original author of that famous phrase. All this was anathema to the exponents of the prevailing theology with which, indeed, it seemed only too surely to dispense; and in Smith's first year at Glasgow the local Presbytery set the whole University in a ferment by prosecuting Hutcheson for teaching to his students, in contravention of his subscription to the Westminster Confession, the following two false and dangerous doctrines: 1st, that the standard of moral goodness was the promotion of the happiness of others; and 2nd, that we could have a knowledge of good and evil without and prior to a knowledge of God. This trial of course excited the profoundest feeling among the students, and they actually made a formal appearance before the Presbytery, and defended their hero zealously both by word and writing. Smith, being only a bajan--a first year's student--would play no leading part in these proceedings, but he could not have lived in the thick of them unmoved, and he certainly--either then or afterwards, when he entered Hutcheson's class and listened to his lectures on natural theology, or perhaps attended his private class on the Sundays for special theological study--adopted the religious optimism of Hutcheson for his own creed, and continued under its influence to the last of his days.
