be no opportunity for these hateful weeds to reach the sun and air. Virtue should actually crowd out vice, and temperance is the tool that youth finds ready to its hand. Temperance means the happy harmonizing and coördinating of the expression of one’s personality; it means health, candor, sincerity, and wisdom,--knowledge of one’s self and the sympathetic understanding of comrades. Justice is a virtue which, if it be not developed in youth, has little chance of ever being developed. It depends on a peculiarly sensitive reaction to good and evil, and it is only in youth that those reactions are keen and disinterested. Real justice is always a sign of great innocence; it cannot exist side by side with interested motives or a trace of self-seeking. And a sense of justice is hard to develop in this great industrial world where the relations of men are so out of joint and where such flaunting anomalies assail one at every turn. Yet in the midst of it all youth is still pure of heart, and it is only the pure of heart who can be just. For in youth we live in a world of clean disinterestedness. We have ambitions and desires, but not yet have we learned the devious way by which they may be realized. We have not learned how to achieve our ends by taking advantage of other people, and using them and their interests and necessities as means. We still believe in the possibility of every man’s realizing himself side by side with us. In early youth, therefore, we have an instinctive and almost unconscious sense of justice. Not yet have we learned the trick of exploiting our fellow men. If we are early assailed with the reality of social disorder, and have brought home to our hearts the maladjustments of our present order, that sense of justice is transformed into a passion. This passion for social justice is one of the most splendid of the ideals of youth. It has the power of keeping alive all the other virtues; it stimulates life and gives it a new meaning and tone. It furnishes the _leit-motiv_ which is so sadly lacking in many lives. And youth must find a _leit-motiv_ of some kind, or its spirit perishes. This social idealism acts like a tonic upon the whole life; it keeps youth alive even after one has grown older in years.
