Identity 3 : What am I?

What sort of things, metaphysically speaking, are you and I and other human people?

What is our basic metaphysical nature?

For instance, what are we made of?

Are we made up entirely of matter, just as stones are, or partly or wholly of something else?

If we are made of matter, what matter is it? (Just the matter that makes up our bodies, or might we be larger or smaller than our bodies?)

Where, in other words, do our spatial boundaries lie?

More fundamentally, what fixes those boundaries?

Are we substances—metaphysically independent beings—or is each of us a state or an aspect of something else, or perhaps some sort of process or event?
