An exaggerated personal morality is often mistaken for a social morality, and until it attempts to minister to a social situation its total inadequacy is not discovered. To attempt to attain a social morality with a basis of democratic experience results in a loss of the only possible corrective and guide, and ends in an exaggerated individual morality but not in social morality at all. We see this from time to time in the care-worn and over-worked philanthropist, who has taxed his individual will beyond the normal limits and has lost his clew to the situation among a bewildering number of cases. A man who takes the betterment of humanity for his aim and end must also take the daily experiences of humanity for the constant correction of his process. He must not only test and guide his achievement by human experience, but he must succeed or fail in proportion as he has incorporated that experience with his own. Otherwise his own achievements become his stumbling-block, and he comes to believe in his own goodness as something outside of himself. He makes an exception of himself, and thinks that he is different from the rank and file of his fellows. He forgets that it is necessary to know of the lives of our contemporaries, not only in order to believe in their integrity, which is after all but the first beginnings of social morality, but in order to attain to any mental or moral integrity for ourselves or any such hope for society.
