Student opinion recognizes that the man enrolled in professional courses or headed for a graduate school faces more stringent necessities. He may devote himself to his more specific training without the imputation of being a “grind,” and if he pursues honours it will be in the line of business rather than of indoor sport. He will be charier of cuts, more painstaking as regards his notes and reading, and the professional manner will settle on him early. In every college commons you can find a table where the talk is largely shop--hypothetical cases, laboratory experiments, new inventions, devices for circumventing the income tax. All this, however, is really a quantitative difference, not a qualitative. Of disinterested intellectual activity he is if anything more innocent than his fellow in the arts school. So much for the four great necessities of average student life--in order of acknowledged importance: athletics, social life, politics, study. Deans and other official but theoretical folk will tell our Martian that the business of college is study and that all the undergraduate’s other functions are marginal matters; but their own conduct will already have betrayed them to him, for he will not have missed the fact that most of their labour is devoted to making study as dignified and popular as the students have made sports and clubs and elections. These four majors hold their places at the head of the list of student emphases because no representative undergraduate quite escapes any of them; the next ones may be stressed more variously, according rather to the student’s capricious private inclinations than to his simpler group reactions.
