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.
To add to this, we've eaten a lot of spheres and cubes as adults as well, it would be strange if you couldn't tell a cherry from a watermelon cube by feel alone
