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.
i think i can understand it by proxy, there are numerous optical illusions where your perception of something flips back and forth (like the duck-rabbit) and i’ve experienced seeing (and hearing) things that others laugh at or find interesting and it took me several days for it to finally click in the brain and from then on i couldn’t unsee it again.
