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.

      And there’s two of them, giving slightly different images (but without the whole circuitry developed at a young age that manages to calculate distances from the slight differences between the two images… hell, they might even lack the circuitry that corrects for the images being upside down, at that!).

        … So, they’ll have to experience the world through its reflection in a spoon.
