Indeed, very few people are aware that in each of our fingers, located somewhere between the first phalange, the mesophalange, and the metaphalange, there is a tiny brain. The fact is that the other organ which we call the brain, the one with which we came into the world, the one which we transport around in our head and which transports us so that we can transport it, has only ever had very general, vague, diffuse and, above all, unimaginative ideas about what the hands and fingers should do. For example, if the brain-in-our-head suddenly gets an idea for a painting, a sculpture, a piece of music or literature, or a clay figurine, it simply sends a signal to that effect and then waits to see what will happen
