Leonard Bilsiter was one of those people who have failed to find this world attractive or interesting, and who have sought compensation in an "unseen world" of their own experience or imagination-or invention. Children do that sort of thing successfully, but children are content to convince themselves, and do not vulgarise their beliefs by trying to convince other people. Leonard Bilsiter's beliefs were for "the few," that is to say, anyone who would listen to him.
