I am not speaking of deceptions or illusions. When I say that all religions depend for their origin and continuance directly upon inspiration, I state an historic fact. It may be known under other names, of credit or discredit, as mysticism, ecstasy, rhapsody, demoniac possession, the divine afflatus, the gnosis, or in its latest christening, “cosmic consciousness.”[41] All are but expressions of a belief that knowledge arises, words are uttered, or actions performed, not through conscious ideation and reflective purpose, but through the promptings of a power above or beyond the individual mind.[42] Prophets and shamans, evangelists and Indian medicine-men, all claim, and all claim with honesty, to be moved by the god within, the deus in nobis, and to speak the words of the Lord.
The intensity of purpose, and the suppression of the reason which everywhere and at all times this sense of inspiration brings with it, cannot be overestimated in their influence on the history of the race. To them are due all fanaticism, religious bigotry, and illiberality.
He who has walked with God, who has felt the pressure of the divine hand, who has been rewarded with the “beatific vision,” to him all lesser ties are weak, all knowledge vain. He will say: “It is better to know God and be ignorant of all else, than to know all else and be ignorant of God.” No reasoning can convince him of error, for his logic acknowledges not the laws of human thought; no appeal will soften his judgments, for he utters not the decision of a man, but the unalterable edict of the God.
Unless we can offer a rational explanation for this universal trait, all religions become inexplicable. Fortunately the investigations of modern psychology enable us to present such an explanation. It teaches us by innumerable examples that by far the majority of the impressions on our senses leave no trace in conscious recollection, although they are stored in the records of the brain; that what seems lost to memory, still lingers in its recesses; and that mental action is constantly going on and reaching results, wholly without our knowledge.
The psychologist calls this process by the terms “unconscious cerebration,” or “psychic automatism.” It is the function of the “sub-limital consciousness,” or, for short, the “sub-consciousness.” Not only is it common, it is constant, and the results of this unperceived labour of our minds is often far more valuable than those of our intelligent efforts. The most complex mechanical inventions, the most impressive art-work of the world, even the most difficult mathematical solutions, have been attained through this unknowing mechanism of mind. They seemed real inspirations, but we may be sure that the mind through long conscious effort had been storing the material and laying the foundation for the perfect edifice which sprang so magically into existence.
The psychologist has gone farther. Not resting content with the detection of this automatic mental machinery, he has studied how it is set a-going, and is prepared to show that in all its forms it can be produced at will under favourable conditions. Like an ancient necromancer, he can inspire and bewitch, he can exorcise demons and cast out devils.
His power is not occult, for it belongs to science, and science has no secrets. It is known as “suggestion,” and in it lies the sociologic power of all religions and superstitions whatever, primitive or present. It is necessary, therefore, that I devote a few words to its explanation.
Suggestion in its simplest form is the indirect evocation of an idea in the mind as the starting-point of a process of thought and feeling. The idea may be impressed by a repetition of the stimulus, by association with allied ideas, or by sensory contacts. It may be evoked by deliberate effort of our own, which is called “auto-suggestion”; or the impression may be derived from or directed to a number of individuals, which is termed “collective suggestion.”
