the strenuous life

Bodily vigor is good, and vigor of intellect is even better, but far above both is character. It is true, of course, that a genius may, on certain lines, do more than a brave and manly fellow who is not a genius; and so, in sports, vast physical strength may overcome weakness, even though the puny body may have in it the heart of a lion. But, in the long run, in the great battle of life, no brilliancy of intellect, no perfection of bodily development, will count when weighed in the balance against that assemblage of virtues, active and passive, of moral qualities, which we group together under the name of character; and if between any two contestants, even in college sport or in college work, the difference in character on the right side is as great as the difference of intellect or strength the other way, it is the character side that will win.
