What am I? If I say I in the sense of Roberto della Griva, I say so inasmuch as I am the memory of all my past moments, the sum of everything I remember. If I say I in the sense of that something that is here at this moment and is not the mainmast or the coral, then I am the sum of what I feel now. But what is what I feel now? It is the sum of those relations between presumed indivisibles that have been arranged in that system of relations in that special order that is my body.
