"I must avert here once again to my view of the opposition that exists between individuality and personality, notwithstanding the fact that the one demands the other. Individuality is, if I may so express it, the container or thing which contains, personality the content or thing contained, or I might say that my personality is in a certain sense my comprehension, that which I comprehend or embrace within myself — which is in a certain way the whole Universe — and that my individuality is my extension; the one my infinite, the other my finite."
