One Foot in Paradise (Philosophical Fragments)

All things in this world are gray. They are all shades and shadows of ultimate existence. Would we even know pure white, if we were to see it? Is there really such a thing as complete blackness?

There can only be one unlimited existence – if there were two, they could not be separated out from one another, for that would require limits. All other existence must be limited. But perfect existence need not be unlimited. Perfection is attained when actual existence reaches its limits – when all potential is fulfilled. A thing's limits determine its potential existence. If morality is black and white, then perfect existence is the purest white; anything imperfect is a shade of gray, because it also contains nonexistence, blackness, within its limits.
