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.

In beautiful Art the principle of the Idealism of purposiveness is still clearer.
