Note 115 — TRANSLATION[107] “PERPETUAL PEACE”[108]

It has been hitherto doubted, not without reason, whether there can be laws of permission (leges permissivæ) of pure reason as well as commands (leges præceptivæ) and prohibitions (leges prohibitivæ). For law in general has a basis of objective practical necessity: permission, on the other hand, is based upon the contingency of certain actions in practice. It follows that a law of permission would enforce what cannot be enforced; and this would involve a contradiction, if the object of the law should be the same in both cases. Here, however, in the present case of a law of permission, the presupposed prohibition is aimed merely at the future manner of acquisition of a right—for example, acquisition through inheritance: the exemption from this prohibition (i.e. the permission) refers to the present state of possession. In the transition from a state of nature to the civil state, this holding of property can continue as a bona fide, if usurpatory, ownership, under the new social conditions, in accordance with a permission of the Law of Nature. Ownership of this kind, as soon as its true nature becomes known, is seen to be mere nominal possession (possessio putativa) sanctioned by opinion and customs in a natural state of society. After the transition stage is passed, such modes of acquisition are likewise forbidden in the subsequently evolved civil state: and this power to remain in possession would not be admitted if the supposed acquisition had taken place in the civilized community. It would be bound to come to an end as an injury to the right of others, the moment its illegality became patent.

I have wished here only by the way to draw the attention of teachers of the Law of Nature to the idea of a lex permissiva which presents itself spontaneously in any system of rational classification. I do so chiefly because use is often made of this concept in civil law with reference to statutes; with this difference, that the law of prohibition stands alone by itself, while permission is not, as it ought to be, introduced into that law as a limiting clause, but is thrown among the exceptions. Thus “this or that is forbidden”,—say, Nos. 1, 2, 3, and so on in an infinite progression,—while permissions are only added to the law incidentally: they are not reached by the application of some principle, but only by groping about among cases which have actually occurred. Were this not so, qualifications would have had to be brought into the formula of laws of prohibition which would have immediately transformed them into laws of permission. Count von Windischgrätz, a man whose wisdom was equal to his discrimination, urged this very point in the form of a question propounded by him for a prize essay. One must therefore regret that this ingenious problem has been so soon neglected and left unsolved. For the possibility of a formula similar to those of mathematics is the sole real test of a legislation that would be consistent. Without this, the so-called jus certum will remain forever a mere pious wish: we can have only general laws valid on the whole; no general laws possessing the universal validity which the concept law seems to demand.
