"In the Bible praise is given, not to the strong man who "taketh a city," but to the stronger man who "ruleth his own spirit." This stronger man is he who, by discipline, exercises a constant control over his thoughts, his speech, and his acts. Nine-tenths of the vicious desires that degrade society, and which, when indulged, swell into the crimes that disgrace it, would shrink into insignificance before the advance of valiant self-discipline, self-respect, and self-control. By the watchful exercise of these virtues, purity of heart and mind become habitual, and the character is built up in chastity, virtue, and temperance."
