“In seeing any object, our eyes and therefore our retinal images are reacting to the object by shifting twenty times a second, and yet we see an unshifting stable object with no consciousness whatever of the succession of different inputs or of putting them together into the object. An abnormally small retinal image of something in the proper context is automatically seen as something at a distance; we are not conscious of making the correction. Color and light contrast effects, and other perceptual constancies all go on every minute of our waking and even dreaming experience without our being in the least conscious of them.”

—Julian Jaynes, from The Origin of Consciousness in the Breakdown of the Bicameral Mind, 1976.
