Leaving whether or not I am a real/whole person aside (how do you quantify personhood, anyway?) the part of me that exists here leaves massive gaps with regard to what I consist of in meatspace. But it is easy to imagine that as I say or make something it departs from my body, leaving a small hole that refills like a fingerprint in sand, remaking me whole and what I expelled as separate as though it came from someone else, only reentering the pool of my mind as anyone else's words might. It is this way and it isn't.
My insides, the outside, and objects charged with keeping them apart.
