Many men with a modicum of mathematical genius work in this way, and in practical life the plan may serve all right. But now it was shown to Newton that a schoolman must not only know how to work out great problems, but also why he goes at it in a certain way; otherwise, colleges are vain--we must be able to pass our knowledge along. The really great man is one who knows the rules and then forgets them, just as the painter of supreme merit must be a realist before he evolves into an impressionist. Newton now acknowledged his mistake in reference to Euclid, and set to work to master the rules. This graciousness in accepting advice, and the willingness to admit his lapse, if he had been hasty, won for him not only the scholarship, but also the love of his superiors. Milton was a radical who made enemies, but Newton was a radical who made friends. He avoided iconoclasm, left all matters of theology to the specialists, and accepted the Church as a necessary part of society. His care not to offend fixed his place in Cambridge for life. It was Cambridge that fostered and encouraged his first budding experiments; it was there he was sustained in his mightiest hazards; and it was within her walls that the ripe fruit of his genius was garnered and gathered. When his fame had become national and he was called to higher offices than Cambridge supplied, Cambridge watched his career with the loving interest of a mother, and the debt of love he fully paid, for it was very largely through his name and fame that Cambridge first took her place as one of the great schools of the world. * * * * * Newton took his degree of Bachelor of Arts at Cambridge, in January, in the year Sixteen Hundred Sixty-five. The faculty of Trinity would not even consider his leaving the college: he was as valuable to them as he would be now if he were a famous football-player. Besides the scholarship, there were ways provided so he could earn money by private tutoring and giving lectures in the absence of the professors. He had written his essay on fluxions, described their application to fluents and tangents, and devised a plan for finding the radius of curvity in crooked lines. In August of the same year that Newton was given his degree, the college was dismissed on account of an epidemic, and Newton went home to Woolsthorpe to kill time. In September, Sixteen Hundred Sixty-five, he then being twenty-three, while seated in his mother's garden, Newton saw that storied apple fall. What pulled it down? Some force tugging at it, surely!
