"He was not accustomed to busying himself with introspection or self-analysis. In this way he was like most people who are rarely alone. His mind did not swing into action until some external force required it: a man or woman or some element of his material life. He had surrendered himself to the busy current of his life, submerging himself totally in it. All he saw of himself was his reflection on the surface of the stream." (p.41)
What a perfect description of the manner in which most people avoid the hard task of self-knowledge and an accurate explanation for why many people are afraid to be alone.
