the blind painter

Eşref Armağan (born 1953) is a blind painter of Turkish origin. He was born blind to a poor family in Turkey, and has been drawing or painting since childhood. In 2004, he was the subject of a study of human perception, conducted by the psychologist John Kennedy of the University of Toronto (watch the video below). His story has revealed that the brain has the potential to adapt and rewire itself according to individual needs. The brain's ability to reorganize its functions based on new information and experiences is defined as neural plasticity. Read more here.

I am so amazed at that last part, when he managed to draw the perspective. It's incredible...how can one know it, when one has never seen it? Yes, one can feel the sides of the building (even on that small-scale model), but how does one know they converge to the horizon, if one has never seen the horizon? The touch does not contain that information and cannot inform one on what the eyes would have seen form a certain point...
