http://www.ritsumei.ac.jp/~akitaoka/index-e.html http://www.ritsumei.ac.jp/~akitaoka/index-e.html These 'Illusions' that trick the mind are based on perceptional biases, more or less hard-coded brain structures that gave its ancestors a survival advantage. They had faster reaction times with some out-of-the-box categories and such. They back-propagate information that filters perception. And its not just those 'Illusions'. In reality, whatever that is, there aren't any vanishing lines meeting at a vanishing point somewhere around infinity. But that 2D graphical user interface in your head comes in handy, moving in a higher dimensional (mostly 3, sometimes 4) reality. So since perception is always subjective illusion (are there any others), science in a sense is parting from Illusions. Something, one or the other religion, strangely also claims for itself.
