What’s in a face, and what can a face tell you about a person? A lot, I’m told, but I have no idea. I was born blind.
I know that most faces have eyes, a nose, a mouth, a forehead, and ears, but how these parts form a whole is something I only understand conceptually. That’s because unlike sight, which takes many images and stitches them together, letting you see an entire object, touch is the opposite: It’s sequential, so you can only touch parts of an object, and then your brain has to guess what the rest of this object might be.
