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 actually felt like my pointy bits method was entirely disconnected from experience. Yeah, they see abstract garbage, but they'll still see anomalies in this abstract garbage. And they were able to feel anomalies on the cube.
It does take some thinking to make a guess like that. And they may have still been completely overwhelmed with sight in general. And again, I don't know what the methodology in these tests looked like. But yeah, just summarizing it as "they could not" seems entirely unhelpful.
Could they tell that there are eight pointy bits? A cube only has between four and seven pointy bits, visually, although the seventh pointy bit would be pointing at them, and I'm not convinced that someone who's never seen before would be able to process what a corner looks like head on. If they could pick the items up to move them around, then they'd simply be able to tell by touch. Even if it was rotating on a turntable or something, they'd have no way to map the two dimensional image onto a three dimensional object in their mind. You can easily visualize how it looks to make one rotation of a cube, but if you've never visualized before, you'd have no way to translate what you're seeing to the model you have in your mind.
100% agree on wanting more than just "they could not," though
Also the whole bit with how eyes give a flattened 2D perspective from a distance of 3D objects they previously only has felt as 3D shapes directly in their hands
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 biiig spoon.
