(3) Another advantage of a systematic study of ethics is that it can make clearer to us why one act is better than another; why duty is justified in thwarting our inclinations and conscience is to be obeyed. Not only is this an intellectual gain, but it is an immense fortification to the will. There comes a time in the experience of every thinking man when a command not reinforced by a reason breeds distrust, and when until he can intelligently defend an ideal he will hesitate to give it his allegiance. Morality, to be depended upon, must be not a mere matter of breeding and convention, or of impulse and emotion, but the result of rational insight and conscious resolve. To many people morality seems nothing but convention, or an arbitrary tyranny, or a mysterious and awful necessity, something extraneous to their own desires, from which they would like to escape. To be able to refute these skeptics, expose the sophisms and specious arguments by which they support their wrongdoing, and show that they have chosen the lesser good, is a valuable help to the community and to one’s own integrity of conduct. Too often the people perish for lack of vision; an understanding of the naturalness and enormous desirability of morality, together with an appreciation of its main injunctions, would enlist upon its side many restless spirits who now chafe under a sense of needless restraint and seek some delusory freedom which leads to pain and death. Morality is simply the best way of living; and the more fully men realize that, the more readily will they submit themselves to the sacrifices it requires.

Widespread public opinion is a force of incalculable power, which is largely unused. Politics and business, and to a far greater extent than now private life, will become clean and honest and kind just so soon as a sufficient number of people wake up and demand it. We have the power to make sins which are now generally tolerated and respectable, so odious, so infamous, that they will practically disappear. There are certain of the older forms of sin which the race in
