In discussing the nature of a revelation we need to remember that, however little or however much, it must be coloured by the man's own past history, traditions, and surroundings, his present conceptions, beliefs, and imaginations. Only when every possible effort has been made by a man to free himself from all these influences can they be reduced to a minimum, and that is the task of philosophy. But that requires that he should really be free outwardly as well as inwardly and therefore not a member of any group, coterie, institution, religion, or organization dealing with the subject upon which he has had a revelation. The more he fails to combat these influences, the more likely is it that some portion, whether it be small or very large, of his revelation is merely an arbitrary creation of his own.
