“ The essence of a thing, if it merely consisted in a simple quality, would therefore with every change be itself totally changed; that is, a new somewhat would take the place of the old as it vanished, and the ‘Thing’ would have in itself no kind of ‘reserve,’ to which, as to its permanent nature, it could withdraw on the occasion of a change in its quality. ”
