Quotes & Sayings About Optical Illusions

I was fascinated with optical illusions. — Temple Grandin

We all know that rainbows are temporary optical illusions based on the factors of sunlight, moisture, and heat. The environment creates each rainbow like the mind creates a self. Both creations are relatively real, in that we can genuinely experience them temporarily; but just as the factors that created the illusion (whether rainbow or self) arose, so will they also pass. There is no permanent self; there is no permanent rainbow. It is not true to say that there is no self at all or that everything is empty or illusory, but it is true that everything is constantly changing and that there is no solid, permanent, unchanging self within the process that is life. Everything and everyone is an unfolding process. — Noah Levine

If a man proves too clearly and convincingly to himself ... that a tiger is an optical illusion
well, he will find out he is wrong. The tiger will himself intervene in the discussion, in a manner which will be in every sense conclusive. — Lord Byron

Long periods of peace and quiet favor certain optical illusions. Among them is the assumption that the invulnerability of the home is founded upon the constitution and safeguarded by it. In reality, it rests upon the father of the family who, accompanied by his sons, appears with the ax on the threshold of his dwelling. — Ernst Junger

He said Manhattan had other problems - whatever that meant. And sometimes when I looked across the water, I could swear I was seeing things. Sadie laughed about it, but once I thought I saw a flying horse. Probably just the mansion's magic barriers causing optical illusions, but still, it was weird. — Rick Riordan

You know, when I was in love, I was always inventing things. A whole array of tricks, illusions and optical effects to amuse my lady friend. I think she'd had enough of my inventions by the end ... I wanted to create a voyage to the moon just for her, but what I should have given her was a real journey on earth. — Mathias Malzieu

Our perceptions are fallible. We sometimes see what isn't there. We are prey to optical illusions. Occasionally we hallucinate. We are error-prone. — Carl Sagan

The boundary between science fiction and social reality is an optical illusion — Donna J. Haraway

I share your feeling that such behavior is, in some sense, unwise or erroneous, but this does not mean that it does not occur,' Amos wrote to an American economist who complained about the description of human nature implied by 'Value Theory.' 'A theory of vision cannot be faulted for predicting optical illusions. Similarly, a descriptive theory of choice cannot be rejected on the grounds that it predicts 'irrational behavior' if the behavior in question is in fact observed. — Michael Lewis

That's when I saw you, really saw you for the first time. I didn't intend to look at you, it just happened. It was like those pictures, you know, those optical illusions. You can gaze at them forever and see only one thing. Then when you relax your eyes for just a moment, another picture magically appears. The funny thing with that kind of visual trick it that it's really hard to go back to seeing the original picture once you've seen the new one. — Kimberly Sabatini

People who have realized that this is a dream imagine that it is easy to wake up, and are angry with those who continue sleeping, not considering that the whole world that environs them does not permit them to wake. Life proceeds as a series of optical illusions, artificial needs and imaginary sensations. — Alexander Herzen

Beauty is the result of clarity and system and not of optical illusion. — Henry Van De Velde

Life presents itself as a continual deception, in small matters as well as in great. If it has promised, it does not keep its word, unless to show how little desirable the desired object was; hence we are deluded now by hope, now by what was hoped for. If it has given, it did so in order to take. The enchantment of distance shows us paradises that vanish like optical illusions, when we have allowed ourselves to be fooled by them. Accordingly, happiness lies always in the future, or else in the past, and the present may be compared to a small dark cloud driven by the wind over the sunny plain; in front of and behind the cloud everything is bright, only it itself always casts a shadow. Consequently, the present is always inadequate, but the future is uncertain, and the past irrecoverable. — Arthur Schopenhauer

There are optical illusions in time as well as space. — Marcel Proust

Your eyes have no power to see. They only create optical illusions. Only the mind can see it when it is ready to see it. — Debasish Mridha

Visual illusions, too, fascinated me; they showed how intellectual understanding, insight, and even common sense were powerless against the force of perceptual distortions. Gibson's inverting glasses showed the power of the mind to rectify optical distortions, where visual illusions showed its inability to correct perceptual ones. — Oliver Sacks

Limitations are nothing more than optical illusions, created by our own self-doubt. — Robert M. Hensel

The mistakes we make when we try to imagine our personal futures are also lawful, regular, and systematic. They, too, have a pattern that tells us about the powers and limits of foresight in much the same way that optical illusions tell us about the powers and limits of eyesight. — Daniel Gilbert

The human brain runs first-class simulation software. Our eyes don't present to our brains a faithful photograph of what is out there, or an accurate movie of what is going on through time. Our brains construct a continuously updated model: updated by coded pulses chattering along the optic nerve, but constructed nevertheless. Optical illusions are vivid reminders of this.47 A major class of illusions, of which the Necker Cube is an example, arise because the sense data that the brain receives are compatible with two alternative models of reality. The brain, having no basis for choosing between them, alternates, and we experience a series of flips from one internal model to the other. The picture we are looking at appears, almost literally, to flip over and become something else. — Richard Dawkins
