“ 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.

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 ”
