“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.”

Joyce Carol Oates Blonde

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

Albert Einstein (1879–1955) German-born physicist and founder of the theory of relativity

“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.”

Marilyn Ferguson (1938–2008) American writer

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

Victor Hugo book Les Misérables

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

Gianni Sarcone (1962) Italian author, artist, designer, and researcher in visual perception and cognitive psychology

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

Jon Elster (1940) Norwegian academic

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

Deb Caletti (1963) American writer

“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.”

Claude Bernard (1813–1878) French physiologist

“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.”

Mary Midgley (1919–2018) British philosopher and ethicist
