As to permissive laws, these are inconceivable side by side with the imperative or prohibitive, not indeed because no law ever permits, but because by the very fact that those are imperative or prohibitive, they are at the same time permissive: every jubeo or veto is at the same time a permitto. Principles, as universal volitions, never permit, because nothing escapes their command; but a single volitional act, affirming itself, does not exclude for that reason the possibility that other volitional acts, indeed infinite acts, should be affirmed; for the singular never exhausts its universal. And laws are volitions of class, they impose groups of single acts—groups that are more or less rich, but always contingent: hence a law always leaves all the other actions and classes of action that can be the object of will unwilled (that is, neither commanded nor prohibited), and, therefore, permitted. And even if we take all the laws formulated up to a given moment, all together they do not exhaust the universal; and if new laws be accumulated, one upon the other, be divided and split up "with panting breath," to obtain complete exhaustion, a progressus in infinitum will certainly be attained, but never exhaustion, which is unattainable. This amounts to saying that outside law or laws, there is always the permitted, the lawful, the indifferent, the privilege, the right, or whatever be termed the concept correlative to that of command, veto, or duty, a duality of terms that expresses the finitude of law; hence, when a determined privilege, a determined legal right, a determined right, has been annulled by a new law, when something previously indifferent has been differentiated, privilege, the permitted, the indifferent, right, always arise from the bosom of the new law.
Mutability of laws.
Another contingent character of the content of laws is their mutability. Laws are changeable, whereas principles, or laws of the universal content, are unchangeable, and ready to give form to all the most various historical material. Since actual conditions are constantly changing, it is necessary to add new laws to the old, to retouch and correct these, or to abolish them altogether. This is to be seen equally in the programmes of individual lives, as in the programmes of social and political laws.
Empirical concepts as to the modes of change.
The question as to the number of modes of changing that laws possess does not concern us, because, philosophically speaking, there is never but one mode: the free will that produces the new law in new conditions of fact. Involuntary changing can only be a formula for indicating certain changes, always voluntary, that occur in a less solemn way than others; but from these, can never be absent the solemnity of the human will that celebrates itself. Thus, in like manner, the question as to whether we should recognize conservation or revolution as the fundamental concept of practical life, does not concern us; for every conservative is at the same time a revolutionary, since he is always obliged to adapt the law that he wishes to preserve to the new facts; and every revolutionary is also a conservative, since he is obliged to start from certain laws that he preserves, at any rate provisionally, that he may change others and substitute for them new laws, which he in his turn intends to preserve. Revolution for revolution's sake, the cult of the Goddess Revolution, is an insane effort, which is so none the less because it has sometimes appeared in History and like all insane efforts it ends with suicide. Revolution revolutionizes itself and turns into reaction. Thus when revolutionaries and conservatives are distinguished and opposed to one another, an empirical distinction is made there also, the meaning of which is to be found in the historical circumstances among which it has arisen. Count Cavour was a conservative in respect to certain problems and revolutionary in respect to certain others, to such a degree that he seemed to the Mazzinians to be a conservative and to the clericals and legitimists a revolutionary. Robespierre, if he were a revolutionary for the Girondins and at last even for the neo-moderate Danton, yet to the eyes of Hébert and of Chaumette seemed to be a conservative, enemy of the free development of the rights of man.
Critique of the eternal Code or natural Right.
We should on the other hand be very careful as to the demand so often made and also so far as possible put into execution, for an eternal code, a limit-legislation or model, a universal, rational, or natural justice, as it has been variously termed. Natural justice, universal legislation, eternal code, claim to fix the transitory and are therefore a contradictory concept: contradictory precisely to the principle of the mutability of laws, which is the necessary consequence of their contingent and historical character. Were natural Right permitted to do what it announces, were God to permit that the affairs of Reality should be carried on according to the ill-assorted ideas of writers and professors, we should witness with the formation and application of the eternal Code, the cessation ipso facto of Development, the end of History, the death of Life and the dissolution of Reality.
Natural justice as the new justice.
This world-ending does not take place, because, though it be possible to dwell in contradiction, it is impossible to make it concrete and actual: God, that is to say Reality, does not permit this. Thus it happens that under the name of natural justice, two sorts of products have existed in turn, or sometimes a mixture of those two different products, which have nothing to do with the programme announced. On the one hand, projects of new laws that seemed better than the old or good by comparison with these judged more or less bad, have been proposed as natural or rational justice, and precisely for this reason the old laws were called unnatural and irrational and the new rational and natural. Just as passionate and erotic temperaments, uninstructed by the experience of their past, swear with the utmost seriousness that their new love will be constant, eternal and their last, so man, when he creates new laws, is often seized with the illusion that his laws will not change as did the old ones, forgetting that the old ones were once young and that they "satisfied divers" in their heyday, to express oneself in the words of the old carnavalesque song. Those natural laws are historical, those eternal laws are transitory, like all the others. All know how in certain times and places, religious tolerance, freedom of trade, private property, constitutional monarchy, have been proclaimed eternal; and in others, the extirpation of unbelievers, commercial protection, communism, the republic, and anarchy.
Natural justice as philosophy of the practical.
