This lawfulness, which is in itself contingent (as far as all the concepts of the understanding are concerned) and which the power of judgement (merely for its own advantage) presumes and presupposes in nature, is a formal purposiveness of nature which we in fact assume in the latter, but which forms the basis neither for a theoretical knowledge of nature nor for a practical principle of freedom; nonetheless, it provides a principle for judging and investigating nature with regard to the general laws through which we arrange the particular cases of experience in order to bring out The possibility of an experience in general is the possibility of empirical cognitions as synthetic judgements.
