"When a trout rising to a fly gets hoooked on a line and finds himself unable to swim about freeely, he begins with a fight which results in struggles and splashes and sometimes an escape. Often, of course, the situation is too tough for him. In the same way the human being struggles with his environment and with the hooks that catch him. Sometimes he masters his difficulties; sometimes they are too much for him. His struggles are all that the world sees and it naturally misunderstands them. It is hard for a free fish to understand what is happening to a hooked one."
