"You cannot count the number of bats in an inkblot because there are none. And yet a man—if he is "bat-minded"—may "see" several."
Gregory Bateson (1972)
"I say that because the common belief is often wrong; because vision is so dominant that sighted people think that they know what red is because they see it. But if you think about it, you know a lot about red besides how it looks. You know it's a property, not an object or an action, and you can’t touch it with your hand. Red is more similar to orange than blue, you know all of that. Blind people know all of that, too."
