weakens or uproots that feeling in [us] which, though not of itself moral, is still a disposition of sensibility that greatly promotes morality or at least prepares the way for it: the disposition, namely, to love something (e.g., beautiful crystal formations, the indescribable beauty of plants) even apart from any intention to use it. (Metaphysics of Morals, Doctrine of Virtue §17, 6:643; Gregor, p. 564)
