In art, the trait that perhaps most impresses and most characterizes true geniuses is the multiplicity. If we take the example of a Fernando Pessoa or a Shakespeare, and analyze their work, it seems incredible that such varied manifestations have come from the same mind. That is to say: if, while we read, we pay attention not to the work, but to the mind that generated it, trying to understand its motivations and intentions, we are impressed to notice how it contains oscillations that are sometimes antagonistic, and how it manages to express them clearly and powerfully. It is as if, confronting it with an ordinary mind, we notice that, on one side, there is a vicious and lukewarm character, and on the other side, there is a limitless creative potentiality.
