The reflective Judgement, which is obliged to ascend from the particular in nature to the universal, requires on that account a principle that it cannot borrow from experience, because its function is to establish the unity of all empirical principles under higher ones, and hence to establish the possibility of their systematic subordination. Such a transcendental principle, then, the reflective Judgement can only give as a law from and to itself. It cannot derive it from outside (because then it would be the determinant Judgement);
