When a teacher of the future comes to point out to the youth of America how the highest rewards of intellect and devotion can be gained, he may say to them, not by subtlety and intrigue; not by wire pulling and demagoguery; not by the arts of popularity; not by skill and shiftiness in following expediency; but by being firm in devotion to the principles of manhood and the application of morals and the courage of righteousness in the public life of our country; by being a man without guile and without fear, without selfishness, and with devotion to duty, devotion to his country.
