Optical Illusions Quotes

“Hallucinations relate to the higher cognitive functions of the brain. I was reading about someone at Columbia who asked volunteers to differentiate between houses and faces. Signals in the frontal cortex became active whenever subjects expected to see a face, irrespective of what the actual stimulus was. They would look at a house and "see" a face. It's called, you know Predictive coding. The brain has an expectation of what it will see, then compares this with information from the eyes. When this goes tits up, hallucinations occur. Our eyes don't present to our brains exact photographs of the things we see. They are more like sketches and impressions chattering along the optic nerve for the brain to interpret. That's what optical illusions are about. The brain's software is perfectly capable of simulating a vision in this way”

“Like the moon shining bright Up high with all its grace, I can only show you at night And hide half of my face.”

“While we only look at Nature it is fair to say that Autumn is the end of the year; but it is still more true that Autumn is the beginning of the year.... Autumn is the time when in fact the leaves bud. Leaves wither because winter begins; but they also wither because spring is already beginning, because new buds are being made, as tiny as percussion caps out of which the spring will crack.... It is only an optical illusion that my flowers die in autumn; for in reality they are born.”

“I looked across the river to Manhattan. It was a great view. When Sadie and I had first arrived at Brooklyn House, Amos had told us that magicians tried to stay out of Manhattan. 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.”

“We're left with so little to go on. Only the present is full enough to seem complete, and even that is an optical illusion. The moment is bleeding off the page. We live on the precipice of our perceptions. At the edge of every living instant, the world shears away like a cliff of ice into the sea of what is forgotten.”

“History, insofar as it accustoms human beings to comprehend the whole of the past and to hasten forward with its conclusions into the far future, conceals the boundaries of birth and death, which enclose the life of the human being so narrowly and oppressively, and with a kind of optical illusion, expands his short existence into endless space, leading the individual imperceptibly over into humanity.”

“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.”
