The great interest which has developed in recent years in the Psychology of Religion, and in the study of mysticism, has most naturally given new interest and prominence to all autobiographical writings which lay bare the inward states and processes of the seeking, or the triumphant soul. Professor William James has stated a well-known fact when he says that religion must be studied in those individuals in whom it is manifested to an extra-normal degree. In other words, we must go to those individuals who have a genius for religion—for whom religion has constituted well nigh the whole of life. George Fox is eminently a character of this sort, as nearly every recent student of personal religion has recognized.
