tilthat: TIL a philosophy riddle from 1688 was recently solved. If a man born blind can feel the differences between shapes such as spheres and cubes, could he, if given the ability, distinguish those objects by sight alone? In 2003 five people had their sight restored though surgery, and, no they could not.
nentuaby: I love when apparently Deep questions turn out to have clear empirical answers.
Well theoretically I could blindfold you, give you a complex 3d object to touch up for about half an hour, make you step back, place the object into a large container full of similar objects, then remove the blindfold and ask you to look for the object in the container.
