But if Beauty, by its very nature, creates this experience of dissatisfaction in the human person, then it is reasonable to conclude that beauty is infinite in quality.
For dissatisfaction is the term given for “not-having”. We want to eat, but we don’t have food, and so we are dissatisfied. But at some point we will be full. At some point — after dinner, most likely — we will say, “no more food!” The experience of hunger, then, is finite. It can be sated, as can the experience of immaterial things, like anger.
But Beauty is never sated. No man in recorded history has ever said “no more Beauty, please.” No man, gazing on Michaelangelo’s Sistine Chapel or watching the sun sink below the Blue Ridge Mountains, has ever said, “This is far too much Beauty. Take it away, for I am full.” If a thing can never be conceived of reaching an end point, then as far as we are concerned, that thing is infinite. We can never think of too many numbers — it is an infinite progression. We can never think of too much Beauty. We can never have too much Beauty. This implies that it too, is infinite.
