When we think of that sense, that feeling, or that inclination which makes us affirm the word "I", we realize that it is difficult to point out what this "I" is, what is its character. For it is something which is beyond human comprehension. That is why a person who wishes to explain, even to himself, what it is, points to what is nearest to him declaring: "This is the one whom I have called "I."" Therefore every soul which has, so to speak, identified itself with anything, has identified itself with the body, its own body, because that is the thing which one feels and realizes to be immediately next to one, and which is intelligible as one's being.
