But the body has another major organ for conveying meaning and emotion – or, rather, it has two of them. Through the hand and its gestures, we can greet, promise, threaten, console, assent or reject, and much else besides. The hand can direct attention or outline a rough but reliable picture of the world – ‘It’s over there’; ‘It’s that big’; ‘It’s shaped like this’ – while sign languages translate the spoken word into hand movements. The hand is also a major instrument of the will, acting on and in the world: through its muscular motions, the hand grasps, strikes, plucks the strings of a guitar, lifts food to the mouth, and so on. Through touch, it is an instrument for conveying rich information about the world to the brain. There are dense neural connections between hand and brain, and each leaves its mark on the other. Some late Victorian anatomists and physiologists believed that all the brain’s thoughts influenced the hand, and early 20th-century phenomenologists liked to say that ‘the hand is the visible part of the brain.’ It’s an organ through which we know about the world, and in its expressive mode it helps others know something about us. But the hand might also be thought to contain information about the mind; it might, indeed, have information inscribed on it, making it a surface to be read and interpreted.
