"Man's world is manifold, and his attitudes are manifold. What is manifold is often frightening because it is not neat and simple. Men prefer to forget how many possibilities are open to them. They like to be told that there are two worlds and two ways. This is comforting because it is so tidy. Almost always one way turns out to be common and the other is celebrated as superior. Those who tell of two ways and praise one are recognised as prophets or great teachers. They save men from confusion and hard choices. They offer a single choice that is easy to make because those who do not take the path that is commended to them live a wretched life.
