“Time is an optical illusion- never quite as soild or strong as we think it is”

“Beauty is a question of optics. All sight is illusion.”

“Our separation from each other is an optical illusion.”

“Human beings have a kind of optical illusion, Einstein once said. We think ourselves separate rather than part of the whole. This imprisons our affection to those few nearest us.”

“The straight line, a respectable optical illusion which ruins many a man.”

“The greatest optical illusion of all is to believe that an image has only one interpretation.”

“Biases are either “hot” (that is, produced by the agent’s motivational system) or “cold” (more similar to optical illusions).”

“No one is ever quite as strong or as weak as you'd think.”

“The mental never influences the physical. It is always the physical that modifies the mental, and when we think that the mind is diseased, it is always an illusion.”

“In fact, the whole idea of illusion seems to make sense only if we accept the reality of the illusory experience as an experience and question only what it seems to be telling us about the outside world. Optical illusions do really hapen. What they can’t do is provide accurate measurements of the outside world. The idea of having, so to speak, two successive layers of illusion here is unworkable.”
