Our eyes only tell us part of what we need to be able to see. The other part is done by the brain, taking the input from the eyes and making guesses or inferences about what's out there in the environment. Usually these inferences are very accurate, but sometimes they lead us astray in the form of visual illusions.  -   Scott Murray     Quotes
