The fluid state is, to all appearance, older than the solid state, and plants as well as animal bodies are fashioned out of fluid nutritive matter, so far as this forms itself in a state of rest. This last of course primarily combines and forms itself in freedom according to a certain original disposition directed towards purposes (which, as will be shown in Part II., must not be judged aesthetically but teleologically according to the principle of realism), but also perhaps in conformity with the universal law of the affinity of materials. Again, the watery fluids dissolved in an atmosphere that is a mixture of different gases, if they separate from the latter on account of cooling, produce snow figures, which in correspondence with the character of the special mixture of gases, often seem very artistic and are extremely beautiful. So, without detracting from the teleological principle by which we judge of organisation, we may well think that the beauty of flowers, of the plumage of birds, or of shell-fish, both in shape and colour, may be ascribed to nature and its faculty of producing forms in an aesthetically purposive way, in its freedom, without particular purposes adapted thereto, according to chemical laws by the arrangement of the material requisite for the organisation in question. But what shows the principle of the _Ideality_ of the purposiveness in the beauty of nature, as that which we always place at the basis of an aesthetical judgement, and which allows us to employ, as a ground of explanation for our representative faculty, no realism of purpose, is the fact that in judging beauty we invariably seek its gauge in ourselves _a priori_, and that our aesthetical Judgement is itself legislative in respect of the judgement whether anything is beautiful or not. This could not be, on the assumption of the Realism of the purposiveness of nature; because in that case we must have learned from nature what we ought to find beautiful, and the aesthetical judgement would be subjected to empirical principles. For in such an act of judging the important point is not, what nature is, or even, as a purpose, is in relation to us, but how we take it. There would be an objective purposiveness in nature if it had fashioned its forms for our satisfaction; and not a subjective purposiveness which depended upon the play of the Imagination in its freedom, where it is we who receive nature with favour, not nature which shows us favour. The property of nature that gives us occasion to perceive the inner purposiveness in the relation of our mental faculties in judging certain of its products--a purposiveness which is to be explained on supersensible grounds as necessary and universal--cannot be a natural purpose or be judged by us as such; for otherwise the judgement hereby determined would not be free, and would have at its basis heteronomy, and not, as beseems a judgement of taste, autonomy.
