This absolute determinability of our mind by abstractions is one of the cardinal facts in our human constitution. Polarizing and magnetizing us as they do, we turn towards them and from them, we seek them, hold them, hate them, bless them, just as if they were so many concrete beings. And beings they are, beings as real in the realm which they inhabit as the changing things of sense are in the realm of space.
Plato gave so brilliant and impressive a defense of this common human feeling, that the doctrine of the reality of abstract objects has been known as the platonic theory of ideas ever since. Abstract Beauty, for example, is for Plato a perfectly definite individual being, of which the intellect is aware as of something additional to all the perishing beauties of the earth. "The true order of going," he says, in the often quoted passage in his 'Banquet,' "is to use the beauties of earth as steps along which one mounts upwards for the sake of that other Beauty, going from one to two, and from two to all fair forms, and from fair forms to fair actions, and from fair actions to fair notions, until from fair notions he arrives at the notion of absolute Beauty, and at last knows what the essence of Beauty is."2 In our last lecture we had a glimpse of the way in which a platonizing writer like Emerson may treat the abstract divineness of things, the moral structure of the universe, as a fact worthy of worship. In those various churches without a God which to-day are spreading through the world under the name of ethical societies, we have a similar worship of the abstract divine, the moral law believed in as an ultimate object. 'Science' in many minds is genuinely taking the place of a religion. Where this is so, the scientist treats the 'Laws of Nature' as objective facts to be revered. A brilliant school of interpretation of Greek mythology would have it that in their origin the Greek gods were only half-metaphoric personifications of those great spheres of abstract law and order into which the natural world falls apart—the sky-sphere, the ocean-sphere, the earth-sphere, and the like; just as even now we may speak of the smile of the morning, the kiss of the breeze, or the bite of the cold, without really meaning that these phenomena of nature actually wear a human face.3
As regards the origin of the Greek gods, we need not at present seek an opinion. But the whole array of our instances leads to a conclusion something like this: It is as if there were in the human consciousness a sense of reality, a feeling of objective presence, a perception of what we may call 'something there,' more deep and more general than any of the special and particular 'senses' by which the current psychology supposes existent realities to be originally revealed. If this were so, we might suppose the senses to waken our attitudes and conduct as they so habitually do, by first exciting this sense of reality; but anything else, any idea, for example, that might similarly excite it, would have that same prerogative of appearing real which objects of sense normally possess. So far as religious conceptions were able to touch this reality-feeling, they would be believed in in spite of criticism, even though they might be so vague and remote as to be almost unimaginable, even though they might be such non-entities in point of whatness, as Kant makes the objects of his moral theology to be.
The most curious proofs of the existence of such an undifferentiated sense of reality as this are found in experiences of hallucination. It often happens that an hallucination is imperfectly developed: the person affected will feel a 'presence' in the room, definitely localized, facing in one particular way, real in the most emphatic sense of the word, often coming suddenly, and as suddenly gone; and yet neither seen, heard, touched, nor cognized in any of the usual 'sensible' ways. Let me give you an example of this, before I pass to the objects with whose presence religion is more peculiarly concerned.
An intimate friend of mine, one of the keenest intellects I know, has had several experiences of this sort. He writes as follows in response to my inquiries:—
"I have several times within the past few years felt the so-called 'consciousness of a presence.' The experiences which I have in mind are clearly distinguishable from another kind of experience which I have had very frequently, and which I fancy many persons would also call the 'consciousness of a presence.' But the difference for me between the two sets of experience is as great as the difference between feeling a slight warmth originating I know not where, and standing in the midst of a conflagration with all the ordinary senses alert.
"It was about September, 1884, when I had the first experience. On the previous night I had had, after getting into bed at my rooms in College, a vivid tactile hallucination of being grasped by the arm, which made me get up and search the room for an intruder; but the sense of presence properly so called came on the next night. After I had got into bed and blown out the candle, I lay awake awhile thinking on the previous night's experience, when suddenly I felt something come into the room and stay close to my bed. It remained only a minute or two. I did not recognize it by any ordinary sense, and yet there was a horribly unpleasant 'sensation' connected with it. It stirred something more at the roots of my being than any ordinary perception. The feeling had something of the quality of a very large tearing vital pain spreading chiefly over the chest, but within the organism—and yet the feeling was not pain so much as abhorrence. At all events, something was present with me, and I knew its presence far more surely than I have ever known the presence of any fleshly living creature. I was conscious of its departure as of its coming: an almost instantaneously swift going through the door, and the 'horrible sensation' disappeared.
"On the third night when I retired my mind was absorbed in some lectures which I was preparing, and I was still absorbed in these when I became aware of the actual presence (though not of the coming) of the thing that was there the night before, and of the 'horrible sensation.' I then mentally concentrated all my effort to charge this 'thing,' if it was evil, to depart, if it was not evil, to tell me who or what it was, and if it could not explain itself, to go, and that I would compel it to go. It went as on the previous night, and my body quickly recovered its normal state.
"On two other occasions in my life I have had precisely the same 'horrible sensation.' Once it lasted a full quarter of an hour. In all three instances the certainty that there in outward space there stood something was indescribably stronger than the ordinary certainty of companionship when we are in the close presence of ordinary living people. The something seemed close to me, and intensely more real than any ordinary perception. Although I felt it to be like unto myself, so to speak, or finite, small, and distressful, as it were, I didn't recognize it as any individual being or person."
Of course such an experience as this does not connect itself with the religious sphere. Yet it may upon occasion do so; and the same correspondent informs me that at more than one other conjuncture he had the sense of presence developed with equal intensity and abruptness, only then it was filled with a quality of joy.
"There was not a mere consciousness of something there, but fused in the central happiness of it, a startling awareness of some ineffable good. Not vague either, not like the emotional effect of some poem, or scene, or blossom, of music, but the sure knowledge of the close presence of a sort of mighty person, and after it went, the memory persisted as the one perception of reality. Everything else might be a dream, but not that."
My friend, as it oddly happens, does not interpret these latter experiences theistically, as signifying the presence of God. But it would clearly not have been unnatural to interpret them as a revelation of the deity's existence. When we reach the subject of mysticism, we shall have much more to say upon this head.
Lest the oddity of these phenomena should disconcert you, I will venture to read you a couple of similar narratives, much shorter, merely to show that we are dealing with a well-marked natural kind of fact. In the first case, which I take from the Journal of the Society for Psychical Research, the sense of presence developed in a few moments into a distinctly visualized hallucination,—but I leave that part of the story out.
"I had read," the narrator says, "some twenty minutes or so, was thoroughly absorbed in the book, my mind was perfectly quiet, and for the time being my friends were quite forgotten, when suddenly without a moment's warning my whole being seemed roused to the highest state of tension or aliveness,
