The first doubt of young people is always a source of intense suffering. Hitherto they have believed what they saw and all they heard; and they have not troubled themselves with motives nor facts beyond those given to them and lying on the surface. But when they find out for themselves that seeming is not necessarily being, and that all people are not as good throughout as they thought them, then they suffer a moral shock which often leads them into a state of practical atheism and despair. Many young people give up altogether when they first open the book of humanity and begin to read beyond the title-page; and, because they have found specks in the cleanest parts, they believe that nothing is left pure. They are as much bewildered as horror-struck, and cannot understand how any one they have loved and respected should have done this or that misdeed. Having done it, there is nothing left to love nor respect further. It is only by degrees that they learn to adjust and apportion, and to understand that the whole creature is not necessarily corrupt because there are a few unhealthy places here and there. But in the beginning this first scorching by the fire of experience is very painful and bad to bear. Then they begin to think the knowledge of the world, as got from books, so wonderful, so profound; and they look on it as a science to be learned by much studying of aphorisms. They little know that not the most affluent amount of phrase knowledge can ever regulate that class of action which springs from a man's inherent disposition; and that it is not facts which teach but self-control which prevents.
