"It is true that the subliminal in man is the largest part of his nature and has in it the secret of the unseeen dynamisms which explain his surface activities. But the lower vital subconscious which is all that this psycho-analysis of Freud seems to know, - and of that it knows only a few ill-lit corners, - is no more than a restricted and very inferior portion of the subliminal whole... to begin by opening up the lower subconscious, risking to raise up all that is foul or obscure in it, is to go out of one's way to invite trouble."
