When eighteen years old (in October, 1818), Macaulay entered Trinity College, Cambridge. But for mathematics he would have been made happy. He writes to his mother: "Oh for words to express my abomination of that science, if a name sacred to the useful and embellishing arts may be applied to the perception and recollection of certain properties in numbers and figures!... 'Discipline' of the mind! Say rather starvation, confinement, torture, annihilation!"[4] There were prizes, but Macaulay was not a prize winner. He was an excellent declaimer and an excellent debater, and undoubtedly might have won more honors had he been willing to work hard on the subjects prescribed, whether he liked them or not. But he was eager to avoid the sciences, and he was not content to be a mere struggler for honors. He was sensible enough to enjoy the companionships the place afforded. He knew something of the value of choosing comrades after his own heart, who were thoroughly genuine and sincere, natural and manly. Even if, as Mr. Morison says, the result of his college course was that "those faculties which were naturally strong were made stronger, and those which were naturally weak received little or no exercise," he wisely spent much time with a remarkable group of young men, among whom Charles Austin was king. Of Austin, John Stuart Mill says, "The impression he gave was that of boundless strength, together with talents which, combined with such apparent force of will and character, seemed capable of dominating the world." And Trevelyan adds, "He certainly was the only man who ever succeeded in dominating Macaulay." Austin it was who turned Zachary Macaulay's eldest son from a Tory into a Whig. The boy had always been interested in the political discussions held in his father's house, a center of consultation for suburban members of Parliament, and had learned to look at public affairs with no thought of ambition or jealous self-seeking. This sort of training, supplemented by his discussions at college, where he soon became a vigorous politician, developed a patriotic, disinterested man.
