Nitrous oxide and ether, especially nitrous oxide, when sufficiently diluted with air, stimulate the mystical consciousness in an extraordinary degree. Depth beyond depth of truth seems revealed to the inhaler. This truth fades out, however, or escapes, at the moment of coming to; and if any words remain over in which it seemed to clothe itself, they prove to be the veriest nonsense. Nevertheless, the sense of a profound meaning having been there persists; and I know more than one person who is persuaded that in the nitrous oxide trance we have a genuine metaphysical revelation.
Some years ago I myself made some observations on this aspect of nitrous oxide intoxication, and reported them in print. One conclusion was forced upon my mind at that time, and my impression of its truth has ever since remained unshaken. It is that our normal waking consciousness, rational consciousness as we call it, is but one special type of consciousness, whilst all about it, parted from it by the filmiest of screens, there lie potential forms of consciousness entirely different. We may go through life without suspecting their existence; but apply the requisite stimulus, and at a touch they are there in all their completeness, definite types of mentality which probably somewhere have their field of application and adaptation. No account of the universe in its totality can be final which leaves these other forms of consciousness quite disregarded. How to regard them is the question—for they are so discontinuous with ordinary consciousness. Yet they may determine attitudes though they cannot furnish formulas, and open a region though they fail to give a map. At any rate, they forbid a premature closing of our accounts with reality. Looking back on my own experiences, they all converge towards a kind of insight to which I cannot help ascribing some metaphysical significance. The keynote of it is invariably a reconciliation. It is as if the opposites of the world, whose contradictoriness and conflict make all our difficulties and troubles, were melted into unity. Not only do they, as contrasted species, belong to one and the same genus, but one of the species, the nobler and better one, is itself the genus, and so soaks up and absorbs its opposite into itself. This is a dark saying, I know, when thus expressed in terms of common logic, but I cannot wholly escape from its authority. I feel as if it must mean something, something like what the Hegelian philosophy means, if one could only lay hold of it more clearly. Those who have ears to hear, let them hear; to me the living sense of its reality only comes in the artificial mystic state of mind.231
I just now spoke of friends who believe in the anaesthetic revelation. For them too it is a monistic insight, in which the other in its various forms appears absorbed into the One.
“Into this pervading genius,” writes one of them, “we pass, forgetting and forgotten, and thenceforth each is all, in God. There is no higher, no deeper, no other, than the life in which we are founded. ‘The One remains, the many change and pass;’ and each and every one of us is the One that remains. … This is the ultimatum. … As sure as being—whence is all our care—so sure is content, beyond duplexity, antithesis, or trouble, where I have triumphed in a solitude that God is not above.”232
This has the genuine religious mystic ring! I just now quoted J. A. Symonds. He also records a mystical experience with chloroform, as follows:—
“After the choking and stifling had passed away, I seemed at first in a state of utter blankness; then came flashes of intense light, alternating with blackness, and with a keen vision of what was going on in the room around me, but no sensation of touch. I thought that I was near death; when, suddenly, my soul became aware of God, who was manifestly dealing with me, handling me, so to speak, in an intense personal present reality. I felt him streaming in like light upon me. … I cannot describe the ecstasy I felt. Then, as I gradually awoke from the influence of the anaesthetics, the old sense of my relation to the world began to return, the new sense of my relation to God began to fade. I suddenly leapt to my feet on the chair where I was sitting, and shrieked out, ‘It is too horrible, it is too horrible, it is too horrible,’ meaning that I could not bear this disillusionment. Then I flung myself on the ground, and at last awoke covered with blood, calling to the two surgeons (who were frightened), ‘Why did you not kill me? Why would you not let me die?’ Only think of it. To have felt for that long dateless ecstasy of vision the very God, in all purity and tenderness and truth and absolute love, and then to find that I had after all had no revelation, but that I had been tricked by the abnormal excitement of my brain.
“Yet, this question remains, Is it possible that the inner sense of reality which succeeded, when my flesh was dead to impressions from without, to the ordinary sense of physical relations, was not a delusion but an actual experience? Is it possible that
