Think of human intelligence. The tendency of human intelligence is to limit. From the hosts of ideas that come to him, man must select; he can only follow one path at a time. As man advances along his chosen path, he finds that it branches right and left; and ever and again he must make a fresh choice. His life may be called an unending choice; and his limitations make him what he is. He must choose his house and a room in his house; he attaches himself to a certain community and to a certain faith. He says, "I am a Christian, an Englishman, a Londoner, an inventor", and so on, as he names qualities and details which in his own opinion constitute his individual self. By his habit of mind he is inclined to begin by looking first at the smallest and most limited aspects of himself.
