We can conceive then of no limitation in an infinite nature; and that which is limitless cannot by its nature be understood. And so every desire for the Beautiful which draws us on in this ascent is intensified by the soul’s very progress toward it. And this is the real meaning of seeing God; never to have this desire satisfied. But fixing our eyes on those things which help us to see, we must ever keep our eyes on those things which help us to see, we must ever keep alive in us the desire to see more and more. And so no limit can be set to our progress toward God: first of all, because no limitation can be put upon the beautiful, and secondly because the increase in our desire for the beautiful cannot be stopped by a sense of satisfaction.
St Gregory of Nyssa
