purposive attuning of the Imagination to agreement with the faculty of concepts in general, it cannot be rule and precept which can serve as the subjective standard of that aesthetical but unconditioned purposiveness in beautiful art, that can rightly claim to please everyone. It can only be that in the subject which is nature and cannot be brought under rules or concepts, i.e. the supersensible substrate of all his faculties (to which no concept of the Understanding extends), and consequently that with respect to which it is the final purpose given by the intelligible [part] of our nature to harmonise all our cognitive faculties. Thus alone is it possible that there should be a priori at the basis of this purposiveness, for which we can prescribe no objective principle, a principle subjective and yet of universal validity.
