Fascinating article about a man whose sight was restored after fifty years. It turns out that while we sighted people imagine that seeing is just light hitting your eyes, there’s a lot more to it. And how weird is it that Virgil didn’t understand shadows? (I mean, I can totally understand how he didn’t, but it’s freaky to think how many everyday concepts depend on visual observation. I’m reminded of the scene in Mask when Eric Stoltz tries to explain “billowy” to the blind girl.)
