Then, like some one moving out of deep shadow into light, he saw the figure of a man come sliding sideways into view, a whitish face following the eye, and the perpendicular line he had first observed broadening out and developing into the complete figure of a human being. It was the patient. He had apparently been standing there in front of the fire all the time. A second eye had followed the first, and both of them stared steadily at the spy-hole, sharply concentrated, yet with a sly twinkle of humour and amusement that made it impossible for the doctor to maintain his position any longer.
He opened the door and went in quickly. As he did so he noticed for the first time the sound of a German band coming in gaily through the open ventilators. In some intuitive, unaccountable fashion the music connected itself with the patient he was about to interview. This sort of prevision was not unfamiliar to him. It always explained itself later.
The man, he saw, was of middle age and of very ordinary appearance; so ordinary, in fact, that he was difficult to describe—his only peculiarity being his extreme thinness. Pleasant—that is, good—vibrations issued from his atmosphere and met Dr. Silence as he advanced to greet him, yet vibrations alive with currents and discharges betraying the perturbed and disordered condition of his mind and brain. There was evidently something wholly out of the usual in the state of his thoughts. Yet, though strange, it was not altogether distressing; it was not the impression that the broken and violent atmosphere of the insane produces upon the mind. Dr. Silence realised in a flash that here was a case of absorbing interest that might require all his powers to handle properly.
"I was watching you through my little peep-hole—as you saw," he began, with a pleasant smile, advancing to shake hands. "I find it of the greatest assistance sometimes—"
But the patient interrupted him at once. His voice was hurried and had odd, shrill changes in it, breaking from high to low in unexpected fashion. One moment it thundered, the next it almost squeaked.
"I understand without explanation," he broke in rapidly. "You get the true note of a man in this way—when he thinks himself unobserved. I quite agree. Only, in my case, I fear, you saw very little. My case, as you of course grasp, Dr. Silence, is extremely peculiar, uncomfortably peculiar. Indeed, unless Sir William had positively assured me—"
"My friend has sent you to me," the doctor interrupted gravely, with a gentle note of authority, "and that is quite sufficient. Pray, be seated, Mr.—"
"Mudge—Racine Mudge," returned the other.
"Take this comfortable one, Mr. Mudge," leading him to the fixed chair, "and tell me your condition in your own way and at your own pace. My whole day is at your service if you require it."
Mr. Mudge moved towards the chair in question and then hesitated.
"You will promise me not to use the narcotic buttons," he said, before sitting down. "I do not need them. Also I ought to mention that anything you think of vividly will reach my mind. That is apparently part of my peculiar case." He sat down with a sigh and arranged his thin legs and body into a position of comfort. Evidently he was very sensitive to the thoughts of others, for the picture of the green buttons had only entered the doctor's mind for a second, yet the other had instantly snapped it up. Dr. Silence noticed, too, that Mr. Mudge held on tightly with both hands to the arms of the chair.
"I'm rather glad the chair is nailed to the floor," he remarked, as he settled himself more comfortably. "It suits me admirably. The fact is—and this is my case in a nutshell—which is all that a doctor of your marvellous development requires—the fact is, Dr. Silence, I am a victim of Higher Space. That's what's the matter with me—Higher Space!"
The two looked at each other for a space in silence, the little patient holding tightly to the arms of the chair which "suited him admirably," and looking up with staring eyes, his atmosphere positively trembling with the waves of some unknown activity; while the doctor smiled kindly and sympathetically, and put his whole person as far as possible into the mental condition of the other.
"Higher Space," repeated Mr. Mudge, "that's what it is. Now, do you think you can help me with that?"
There was a pause during which the men's eyes steadily searched down below the surface of their respective personalities. Then Dr. Silence spoke.
"I am quite sure I can help," he answered quietly; "sympathy must always help, and suffering always owns my sympathy. I see you have suffered cruelly. You must tell me all about your case, and when I hear the gradual steps by which you reached this strange condition, I have no doubt I can be of assistance to you."
He drew a chair up beside his interlocutor and laid a hand on his shoulder for a moment. His whole being radiated kindness, intelligence, desire to help.
"For instance," he went on, "I feel sure it was the result of no mere chance that you became familiar with the terrors of what you term Higher Space; for Higher Space is no mere external measurement. It is, of course, a spiritual state, a spiritual condition, an inner development, and one that we must recognise as abnormal, since it is beyond the reach of the world at the present stage of evolution. Higher Space is a mythical state."
"Oh!" cried the other, rubbing his birdlike hands with pleasure, "the relief it is to be able to talk to some one who can understand! Of course what you say is the utter truth. And you are right that no mere chance led me to my present condition, but, on the other hand, prolonged and deliberate study. Yet chance in a sense now governs it. I mean, my entering the condition of Higher Space seems to depend upon the chance of this and that circumstance. For instance, the mere sound of that German band sent me off. Not that all music will do so, but certain sounds, certain vibrations, at once key me up to the requisite pitch, and off I go. Wagner's music always does it, and that band must have been playing a stray bit of Wagner. But I'll come to all that later. Only first, I must ask you to send away your man from the spy-hole."
John Silence looked up with a start, for Mr. Mudge's back was to the door, and there was no mirror. He saw the brown eye of Barker glued to the little circle of glass, and he crossed the room without a word and snapped down the black shutter provided for the purpose, and then heard Barker snuffle away along the passage.
"Now," continued the little man in the chair, "I can begin. You have managed to put me completely at my ease, and I feel I may tell you my whole case without shame or reserve. You will understand. But you must be patient with me if I go into details that are already familiar to you—details of Higher Space, I mean—and if I seem stupid when I have to describe things that transcend the power of language and are really therefore indescribable."
"My dear friend," put in the other calmly, "that goes without saying. To know Higher Space is an experience that defies description, and one is obliged to make use of more or less intelligible symbols. But, pray, proceed. Your vivid thoughts will tell me more than your halting words."
An immense sigh of relief proceeded from the little figure half lost in the depths of the chair. Such intelligent sympathy meeting him half-way was a new experience to him, and it touched his heart at once. He leaned back, relaxing his tight hold of the arms, and began in his thin, scale-like voice.
"My mother was a Frenchwoman, and my father an Essex bargeman," he said abruptly. "Hence my name—Racine and Mudge. My father died before I ever saw him. My mother inherited money from her Bordeaux relations, and when she died soon after, I was left alone with wealth and a strange freedom. I had no guardian, trustees, sisters, brothers, or any connection in the world to look after me. I grew up, therefore, utterly without education. This much was to my advantage; I learned none of that deceitful rubbish taught in schools, and so had nothing to unlearn when I awakened to my true love—mathematics, higher mathematics and higher geometry. These, however, I seemed to know instinctively. It was like the memory of what I had deeply studied before; the principles were in my blood, and I simply raced through the ordinary stages, and beyond, and then did the same with geometry. Afterwards, when I read the books on these sub
jects, I understood how swift and undeviating the knowledge had come back to me. It was simply memory. It was simply re-collecting the memories of what I had known before in a previous existence and required no books to teach me."
In his growing excitement, Mr. Mudge attempted to drag the chair forward a little nearer to his listener, and then smiled faintly as he resigned himself instantly again to its immovability, and plunged anew into the recital of his singular "disease."
"The audacious speculations of Bolyai, the amazing theories of Gauss—that through a point more than one line could be drawn parallel to a given line; the possibility that the angles of a triangle are together greater than two right angles, if drawn upon immense curvatures—the breathless intuitions of Beltrami and Lobatchewsky—all these I hurried through, and emerged, panting but unsatisfied, upon the verge of my—my new world, my Higher Space possibilities—in a word, my disease!
"How I got there," he resumed after a brief pause, during which he appeared to be listening intently for an approaching sound, "is more than I can put intelligibly into words. I can only hope to leave your mind with an intuitive comprehension of the possibility of what I say.
"Here, however, came a change. At this point I was no longer absorbing the fruits of studies I had made before; it was the beginning of new efforts to learn for the first time, and I had to go slowly and laboriously through terrible work. Here I sought for the theories and speculations of others. But books were few and far between, and with the exception of one man—a 'dreamer,' the world called him—whose audacity and piercing intuition amazed and delighted me beyond description, I found no one to guide or help.
"You, of course, Dr. Silence, understand something of what I am driving at with these stammering words, though you cannot perhaps yet guess what depths of pain my new knowledge brought me to, nor why an acquaintance with a new development of space should prove a source of misery and terror."
Mr. Racine Mudge, remembering that the chair would not move, did the next best thing he could in his desire to draw nearer to the attentive man facing him, and sat forward upon the very edge of the cushions, crossing his legs and gesticulating with both hands as though he saw into this region of new space he was attempting to describe, and might any moment tumble into it bodily from the edge of the chair and disappear form view. John Silence, separated from him by three paces, sat with his eyes fixed upon the thin white face opposite, noting every word and every gesture with deep attention.
"This room we now sit in, Dr. Silence, has one side open to space—to Higher Space. A closed box only seems closed. There is a way in and out of a soap bubble without breaking the skin."
"You tell me no new thing," the doctor interposed gently.
"Hence, if Higher Space exists and our world borders upon it and lies partially in it, it follows necessarily that we see only portions of all objects. We never see their true and complete shape. We see their three measurements, but not their fourth. The new direction is concealed from us, and when I hold this book and move my hand all round it I have not really made a complete circuit. We only perceive those portions of any object which exist in our three dimensions; the rest escapes us. But, once we learn to see in Higher Space, objects will appear as they actually are. Only they will thus be hardly recognisable!
"Now, you may begin to grasp something of what I am coming to."
"I am beginning to understand something of what you must have suffered," observed the doctor soothingly, "for I have made similar experiments myself, and only stopped just in time—"
"You are the one man in all the world who can hear and understand, and sympathise," exclaimed Mr. Mudge, grasping his hand and holding it tightly while he spoke. The nailed chair prevented further excitability.
"Well," he resumed, after a moment's pause, "I procured the implements and the coloured blocks for practical experiment, and I followed the instructions carefully till I had arrived at a working conception of four-dimensional space. The tessaract, the figure whose boundaries are cubes, I knew by heart. That is to say, I knew it and saw it mentally, for my eye, of course, could never take in a new measurement, or my hands and feet handle it.
"So, at least, I thought," he added, making a wry face. "I had reached the stage, you see, when I could imagine in a new dimension. I was able to conceive the shape of that new figure which is intrinsically different to all we know—the shape of the tessaract. I could perceive in four dimensions. When, therefore, I looked at a cube I could see all its sides at once. Its top was not foreshortened, nor its farther side and base invisible. I saw the whole thing out flat, so to speak. And this tessaract was bounded by cubes! Moreover, I also saw its content—its insides."
"You were not yourself able to enter this new world," interrupted Dr. Silence.
"Not then. I was only able to conceive intuitively what it was like and how exactly it must look. Later, when I slipped in there and saw objects in their entirety, unlimited by the paucity of our poor three measurements, I very nearly lost my life. For, you see, space does not stop at a single new dimension, a fourth. It extends in all possible new ones, and we must conceive it as containing any number of new dimensions. In other words, there is no space at all, but only a spiritual condition. But, meanwhile, I had come to grasp the strange fact that the objects in our normal world appear to us only partially."
Mr. Mudge moved farther forward till he was balanced dangerously on the very edge of the chair. "From this starting point," he resumed, "I began my studies and experiments, and continued them for years. I had money, and I was without friends. I lived in solitude and experimented. My intellect, of course, had little part in the work, for intellectually it was all unthinkable. Never was the limitation of mere reason more plainly demonstrated. It was mystically, intuitively, spiritually that I began to advance. And what I learnt, and knew, and did is all impossible to put into language, since it all describes experiences transcending the experiences of men. It is only some of the results—what you would call the symptoms of my disease—that I can give you, and even these must often appear absurd contradictions and impossible paradoxes.
"I can only tell you, Dr. Silence"—his manner became exceedingly impressive—"that I reached sometimes a point of view whence all the great puzzle of the world became plain to me, and I understood what they call in the Yoga books 'The Great Heresy of Separateness'; why all great teachers have urged the necessity of man loving his neighbour as himself; how men are all really one; and why the utter loss of self is necessary to salvation and the discovery of the true life of the soul."
He paused a moment and drew breath.
"Your speculations have been my own long ago," the doctor said quietly. "I fully realise the force of your words. Men are doubtless not separate at all—in the sense they imagine—"
"All this about the very much Higher Space I only dimly, very dimly, conceived, of course," the other went on, raising his voice again by jerks; "but what did happen to me was the humbler accident of—the simpler disaster—oh, dear, how shall I put it—?"
He stammered and showed visible signs of distress.
"It was simply this," he resumed with a sudden rush of words, "that, accidentally, as the result of my years of experiment, I one day slipped bodily into the next world, the world of four dimensions, yet without knowing precisely how I got there, or how I could get back again. I discovered, that is, that my ordinary three-dimensional body was but an expression—a projection—of my higher four-dimensional body!
"Now you understand what I meant much earlier in our talk when I spoke of chance. I cannot control my entrance or exit. Certain people, certain human atmospheres, certain wandering forces, thoughts, desires even—the radiations of certain combinations of colour, and above all, the vibrations of certain kinds of music, will suddenly throw me into a state of what I can only describe as an intense and terrific inner vibration—and behold I am off! Off in the direction at right angles to all our known directions! Off in the direction the cube t
akes when it begins to trace the outlines of the new figure! Off into my breathless and semi-divine Higher Space! Off, inside myself, into the world of four dimensions!"
He gasped and dropped back into the depths of the immovable chair.
"And there," he whispered, his voice issuing from among the cushions, "there I have to stay until these vibrations subside, or until they do something which I cannot find words to describe properly or intelligibly to you—and then, behold, I am back again. First, that is, I disappear. Then I reappear."
"Just so," exclaimed Dr. Silence, "and that is why a few—"
"Why a few moments ago," interrupted Mr. Mudge, taking the words out of his mouth, "you found me gone, and then saw me return. The music of that wretched German band sent me off. Your intense thinking about me brought me back—when the band had stopped its Wagner. I saw you approach the peep-hole and I saw Barker's intention of doing so later. For me no interiors are hidden. I see inside. When in that state the content of your mind, as of your body, is open to me as the day. Oh, dear, oh, dear, oh, dear!"
Mr. Mudge stopped and again mopped his brow. A light trembling ran over the surface of his small body like wind over grass. He still held tightly to the arms of the chair.
"At first," he presently resumed, "my new experiences were so vividly interesting that I felt no alarm. There was no room for it. The alarm came a little later."
"Then you actually penetrated far enough into that state to experience yourself as a normal portion of it?" asked the doctor, leaning forward, deeply interested.
Mr. Mudge nodded a perspiring face in reply.
"I did," he whispered, "undoubtedly I did. I am coming to all that. It began first at night, when I realised that sleep brought no loss of consciousness—"
