 The palfrey, by contrast, moves lightly and appears to weigh nothing: its movements are “an effect of its nature than has been left to itself” (NA XXVI, 205/KL 164). This, Schiller says, is a kind of autonomy: the palfrey is determined by its own nature, not by gravity or function. The beauty of animals generally decreases the more they appear determined by gravity, not form: in the case of a light-footed horse, form masters matter; in the case of a duck, matter masters form (NA XXVI, 205/KL 164).
