"Optical illusion" Quotes from Famous Books
 ... of conclusions. Experience, by its passive weight of joy and sorrow, can neither inspire nor prevent enthusiasm; only a present ideal will avail to move the will and, if realised, to justify it. A saint's halo is an optical illusion; it glorifies his actions whatever their eventual influence in the world, because they seem to have, when rehearsed dramatically, some tenderness or rapture or ...
— The Life of Reason • George Santayana
... railway traveling which we do not remember to have seen noticed, however commonplace the mode of transit itself may have become. There is a singular optical illusion, for instance, in going through a tunnel, which nearly every one must have observed, and yet which nobody, so far as we can learn, has thought it worth while to explain: no sooner have you plunged into ...

... upon it, and behold! instead of twinkling points of light, he saw a round mass—a world—moving through space, and not a scintillating object with five points. The twinkling spikes, or points, were merely an optical illusion of the ...

... room, however, a figured carpet is often preferred for practical reasons: it stands wear and tear around the table better. Well-chosen paper (See Chapter II) often improves a badly proportioned room by optical illusion. The ideal lightings for dining rooms are side lights. Dining-room drop lights or domes are very trying to the eyes of those who dine, and are unbecoming. Side lights (adding candles for grace and charm) are far pleasanter to the ...
— Prepare and Serve a Meal and Interior Decoration • Lillian B. Lansdown
... course the most attractive feature in the landscape. Far to the north and south it stretches, like a silver, sinuous thread, gradually becoming narrower until it is lost in the distance. Owing to an optical illusion the river seems to ascend in both directions, and at the points where it is lost to view, seems on a level with the eye. It is one of the best examples of this species of optical illusion to be found in this part ...

... "An optical illusion, my boy," said the captain quietly. "Sit down. You have heard of refraction. It is a peculiar state of the air. I daresay we look the same to them. Pull, my lads. I'm afraid the mist will be down upon us before we can reach the ship. Look ...
— Steve Young • George Manville Fenn
... "Pilgrim," which gradually grew smaller in the distance. This rapidity with which objects diminish at sea has always an odd effect. It seems as if we look at them shortened through the large end of a telescope. This optical illusion evidently takes place because there are no points of comparison on these large spaces. It was thus with the "Pilgrim," which decreased to the eye and seemed already much more ...
— Dick Sand - A Captain at Fifteen • Jules Verne
... longer LIVED on board. The entire ship's crew were undergoing a nervous excitement, of which I can give no idea: they could not eat, they could not sleep—twenty times a day, a misconception or an optical illusion of some sailor seated on the taffrail, would cause dreadful perspirations, and these emotions, twenty times repeated, kept us in a state of excitement so violent that ...

... her eyes to catch a glimpse of her little pupils, could discover nothing but a group of persons that seemed to be the sole survivors of some titanic race. Not one among them but seemed to have reached the high-water mark of six feet. Was it an optical illusion, a hallucination born of the wonderful starlight? Or were they as huge as they seemed? The young men looked giants, the girls as if they had wandered out of the first chapters of Genesis. Their mother introduced them. They all had huge, warm, perspiring hands, with grips like bears. ...
— Judith Of The Plains • Marie Manning
... sourly. "We've got one optical illusion, they've got another, Max. Over there they claim the proletariat owns the means of production. Great. But the Party members are the ones who control it, and, as a result they manage to do all right for themselves. The Party ...
— Mercenary • Dallas McCord Reynolds
... regarding the street I saw a house which amazed me. I thought I must be mistaken: I looked at it more closely,—looked at the houses near it, compared them with the first house and then with each other, and even then I believed that it was an optical illusion. I turned hastily down a side street, and still I seemed to see the same thing. At last I was persuaded that the fault was not with my eyes, but with the ...
— Holland, v. 1 (of 2) • Edmondo de Amicis
... III. An Optical Illusion.—In the sphere of vision many very interesting facts are constantly coming to light. Sight is the most complex of the senses, the most easily deranged, and, withal, the most necessary to our normal existence. The report of the following experimental ...

... a hamlet near Netheravon, I fancied I was witnessing an optical illusion: the whole surface of a field was covered with black and white, vibrating as though waves were passing over it. When we came nearer we saw that the field was covered so thick with gulls that the ground was hidden. The gull was a ...
— On the Fringe of the Great Fight • George G. Nasmith
... be in the sky—a faint red glow, across which shadows appeared to move like phantoms. Like a picture from the ghost world, it flickered for a few minutes like heat lightning, then disappeared, leaving the night as dark as before. It was a night mirage, and something more than an optical illusion. It was a rare thing on the plain. The Kid knew that it meant something. That glow was the reflection in the sky of a camp fire! Those shadows were men! The Texan quickly told ...

... president caught at a glance the consequences of these three hypotheses, either of which would, one way or the other, bring their experiment to an unsuccessful and fatal termination. His companions stood silently looking into space. The object grew rapidly as it approached them, and by an optical illusion the projectile seemed to be ...

— The Teeth of the Tiger • Maurice Leblanc
... the essence of the social, but the location, the sphere, the extent, of the social. If we can agree where it is, we may then proceed to discover what it is. The social, then, is the term next beyond the individual. Assuming, for the sake of analysis, that our optical illusion, "the individual," is an isolated and self-sufficient fact, there are many sorts of scientific problems that do not need to go beyond this fact to satisfy their particular terms. Whether the individual can ever be abstracted from his conditions and remain himself is not a question that ...
— Introduction to the Science of Sociology • Robert E. Park
... understood that the subject was disagreeable; and beyond an inquiry of the Doctor, "How is your patient this morning?" nothing was said. But all felt vaguely there was some mystery. Doctor Frank's theory of optical illusion satisfied no one—there was something at the bottom that they did ...

... him mechanically, still holding the book he had lent me clasped in my hand. Irresolutely I raised my eyes towards the "Lords of our Life and Death." It was closely veiled. I had then experienced an optical illusion. I forced myself to speak—to smile—to put back the novel sensations ...

... in the world to me just then. While congratulating myself on having escaped death on the roadside, I opened my eyes to behold a tray brought to my bedside with a variety of refreshments. Coffee! Bread! Loaf-sugar! Preserves! I opened my mouth to make an exclamation at the singular optical illusion, but wisely forbore speaking, and shut it with some ...

... conceited that if you were to tell them that every time you look at a German you see two men, they would believe you; and then as if they hated to lie to themselves, they would say perhaps it was an optical illusion. Tell them that God did not create anyone but the Germans and that he left the rest of the world to the students in his office, and they will give you a smile of assent." Edestone smiled indulgently. "Tell them that when the Kaiser frowns every wheel in the United States stops and refuses ...

... did not appear. Each evening the sun as it went down dipped behind an interminable horizon of water. The crews who had several times been the victims of an optical illusion, now began to murmur against Columbus, "the Genoese, the foreigner," who had enticed them so far away from their country. Some symptoms of mutiny had already shown themselves on board the vessels, when, on the 10th of October, the sailors openly declared that they would go no further. In treating ...

... This interesting optical illusion—which suggests the wonderful island in the Atlantic, seen from the isles of Aran near Galway, alluded to in the 'Chorographical description of West, or H-Ier-Connaught', of R. O'Flaherty—was caused by the peculiar angle of the light from the setting ...

... neighbourhood; not even a policeman was visible; and the experience gave him a creepy feeling. Then to his amazement Cleopatra's Needle slowly toppled from its pedestal and fell with a crash across the roadway. At first he thought it an optical illusion and wiped his eyes again, but it was nothing of the kind. The monument, which had a moment before pointed to the zenith, now lay shattered in three pieces upon the softening concrete of the drive. The stranger arose and examined the fragments of the monolith, one ...
— The Man Who Rocked the Earth • Arthur Train
... undefinable objects floating motionless above the earth. The telegraph poles traversing the plain in a long, straight line until lost to view in the hazy distance, appear to be suspended in mid-air; camels, horses, and all moving objects more than a mile away, present the strange optical illusion of animals walking through the air many feet above the surface of the earth. Long rows of kanaat mounds traverse the plain in every direction, leading from the numerous villages to distant mountain chains. Descending one of the sloping cavernous entrances before mentioned, ...

... the white drift, eagerly making mental notes of any remarkable mutations in the colouring of the thickly strewn eggs, and admiring the fortitude or indifference with which the fledglings endured the sizzling heat, I found myself subject to an optical illusion, for when I looked up and abroad the brightly gleaming sea had been changed to inky purple, the hills of the mainland to black. Though absolutely cloudless, the sky seemed oppressed with slaty ...

... they happen quickly. My weakness was total ignorance. In particular, my fingers lacked training, and I made the mistake of depending on my eyes to handle the reins. This brought me up against a disastrous optical illusion. The bight of the off head-line, being longer and heavier than that of the off wheel-line, hung lower. In a moment requiring quick action, I invariably mistook the two lines. Pulling on what I thought was the wheel-line, ...
— The Human Drift • Jack London
... of the cone-space; and the deficiency thus produced would disclose to an observer at the earth all the appearances of a spot upon the surface of the sun. The so-called spot, thus produced, might therefore not be regarded as a veritable spot upon the sun's disc, but rather as an optical illusion. ...

... of which, once white, have been blackened by every species of exhalation. Such is, in all its simple modesty, the aspect of a temple consecrated to the worship of Bacchus and Terpsichore. At first, by a very natural optical illusion, we are struck by the confined space before us, but the eye, after a time, piercing through the thick atmosphere of a thousand vapours which are most inodorous, the extent becomes visible by details which escape in the first chaotic glimpse. ...

... to force every atom of vision from my eyes. For a long time I thought they must every moment disappear and resolve themselves into the movements of the branches and prove to be an optical illusion. I searched everywhere for a proof of reality, when all the while I understood quite well that the standard of reality had changed. For the longer I looked the more certain I became that these figures were real and living, though perhaps ...
— The Willows • Algernon Blackwood
... that what I had just seen near Beddgelert was an optical illusion. I had become very learned on the subject of optical illusions ever since I had known Sinfi Lovell, and especially since I had seen that picture of Winnie in the water near Bettws y Coed, which I have described in an earlier chapter. Every book I could get upon optical illusions I had ...
— Aylwin • Theodore Watts-Dunton
... Another optical illusion is afforded by Fig. 142. Two sets of circles are described about different centres, and the crescent-shaped areas between them coloured, the remainder of the disc being left white. The disc is revolved about the centre of the white areas, and one gets the impression that the coloured ...

... posture; but the smile faded and was replaced by a gaze of mute astonishment as he observed that he had depicted Waller's right eye upon his chin, close beneath his nose! There seemed to be some sort of magic here, and he felt disposed to regard the thing in the light of some serious optical illusion, when, on closer inspection, he discovered Waller's mouth drawn altogether beyond the circle of his countenance, a foot or so above his head, on the stem of the tree against which he leaned. This changed the current of his thoughts and led him to believe that he must be dreaming, under ...

... remained but the blue sky above, and the deep blue water below. Hence it was termed by the geographers of old, Aprositus, or the Inaccessible; while modern navigators have called its very existence in question, pronouncing it a mere optical illusion, like the Fata Morgana of the Straits of Messina; or classing it with those unsubstantial regions known to mariners as Cape Flyaway, and the ...
— Wolfert's Roost and Miscellanies • Washington Irving
... were not crocuses; but there could be no doubt of the vineyards increasing in their acreage; and the farmhouses which had been without windows in their outer walls, now sometimes opened as many as two to the passing train. Flocks of black sheep and goats, through the optical illusion frequent in the Spanish air, looked large as cattle in the offing. Only in one place had we seen the tumbled boulders of Old Castile, and there had been really no greater objection to La Mancha than that it was flat, stale, and unprofitable and wholly unimaginable ...
— Familiar Spanish Travels • W. D. Howells
... comfortless on the edge of a rush-bottomed chair, with its shadowy knees drawn up till they nearly touched its shadowy chin. There was something about the outline of this figure so indefinite and unsubstantial, that you might have taken it for an optical illusion, a spectral apparition on the point of vanishing. This thing was, however, possessed of voice, and was speaking in a low but distinct hissing whisper. As the whisper ended, Arabella Crane, without turning her face, spoke, also under ...

... you cast up a feather it sails away on the air and goes out of sight; then you throw up a clod and it doesn't. It comes down, every time. I have tried it and tried it, and it is always so. I wonder why it is? Of course it DOESN'T come down, but why should it SEEM to? I suppose it is an optical illusion. I mean, one of them is. I don't know which one. It may be the feather, it may be the clod; I can't prove which it is, I can only demonstrate that one or the other is a fake, and let a person take ...

... existence exactly, and yet there is a strange fascination about the idea that I can't understand. Now I do not believe we saw a man walking on fog the other night, and yet I can't resist the desire to hunt the matter out and discover what sort of an optical illusion it was. I am not at all certain the man who took a shot at us was the one we saw across the ravine, either. I had an experience once when I was about nine years old, that, in a way, tainted my mind with the ghost idea, and ...

... gulf. Thus the whole visible earth appears as a vast bowl or basin. This is extremely ingenious reasoning, and not to be disregarded; but the fact remains that in the experience of the writer and of many others whom he has consulted, there is no such optical illusion as I have just discussed, and to their vision it is impossible to regard the earth as anything but ...
