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.
In fairness you spend a lot of your childhood licking everything you come across. I bet your tongue has touched many more of those objects than you can remember.
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
