The most influential and representative dimension of comparative legal studies is the attempt to substantiate the universal nature of law. The basis of self-identification of comparative law as an independent legal science is the provision of legal knowledge of generally accepted scientific content, formed by natural science Modern time. Universal and invariant content of law should be equivalent to laws of nature. Supranational and non-national universality is established within the two main paradigms of universality of law. The first is the paradigm of causal universality, which explains the identity of the content of law by influencing the law of the same non-legal factors. The second is the paradigm of teleological universality, which considers the universal content of law as one formed by jurisprudence itself. The dialectic of the paradigm is the content of the comparative discourse on the nature of legal universals.

become a universal law." Closely connected with this formulation is the law of nature formulation. Because laws of nature are by definition universal, Kant The categorical imperative (German: Kategorischer Imperativ) is the central philosophical concept in the deontological moral philosophy of Immanuel Kant. Introduced in Kant's 1785 Groundwork of the Metaphysics of Morals, it is a way of evaluating motivations for action. It is best known in its original formulation: "Act only according to that maxim whereby you can at the same time will that it sho Closely connected with this formulation is the law of nature formulation. Because laws of nature are by definition universal, Kant claims we may also express the categorical imperative as:Act as if the maxims of your action were to become through your will a universal law of nature.Kant divides the duties imposed by this formulation into two sets of two subsets. The first division is between duties that we have to ourselves versus those we have to others. For example, we have an obligation not to kill ourselves as well as an obligation not to kill others. Kant also, however, introduces a distinction between perfect and imperfect duties. [H]e cannot possibly will that this should become a universal law of nature or be implanted in us as such a law by a natural instinct. For as a rational being he necessarily wills that all his faculties should be developed, inasmuch as they are given him for all sorts of possible purposes. But even though it is possible that a universal law of nature could subsist in accordance with that maxim, still it is impossible to will that such a principle should hold everywhere as a law of nature. For a will that resolved in this way would contradict itself, inasmuch as cases might often arise in which one would have need of the love and sympathy of others and in which he would deprive himself, by such a law of nature springing from his own will, of all hope of the aid he wants for himself.
