Philosophy fully admits and believes in the possibility of revelations, be they religious, mystical, or even psychical, but it points out that to the extent that the seer mixes in the picturizations of his own imaginative faculty or the ratiocinations of his own thinking process, to that extent what he receives or gives out is no longer a revelation. It is only an ordinary idea. Philosophy goes even farther than that and asserts that his human ego may interfere unconsciously with the very process whereby he becomes aware of the revelation. When that happens his awareness is tinged by inherited traits or by suggested beliefs or by personal wishes.
