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.
That's because you have prior experience of both seeing and touching those shapes, so your brain has learned to integrate the different sensations
So you're saying we need to get blind people to lick things before their sight is restored
