"The apple certainly exists, but to the core [soul] this existence as yet seems inadequate; if words cannot endorse it, then the only way to endorse it is with the eyes. Indeed, for the core the only sure mode of existence is to exist and to see at the same time. There is only one method of solving this contradiction. It is for a knife to be plunged deep into the apple so that it is split open and the core is exposed to the light-to the same light, that is, as the surface skin. Yet then the existence of the cut apple falls into fragments; the core of the apple sacrifices existence for the sake of seeing."
