cannot be asked to give up its constitution, even although that be a despotism (which is, at the same time, the strongest constitution where foreign enemies are concerned), so long as it runs the risk of being immediately swallowed up by other states. Hence, when such a proposal is made, the state whose constitution is in question must at least be allowed to defer acting upon it until a more convenient time.[148] [148] These are _permissive_ laws of reason which allow us to leave a system of public law, when it is tainted by injustice, to remain just as it is, until everything is entirely revolutionised through an internal development, either spontaneous, or fostered and matured by peaceful influences. For any legal constitution whatsoever, even although it conforms only slightly with the spirit of law is better than none at all—that is to say, anarchy, which is the fate of a precipitate reform. Hence, as things now are, the wise politician will look upon it as his duty to make reforms on the lines marked out by the ideal of public law. He will not use revolutions, when these have been brought about by natural causes, to extenuate still greater oppression than caused them, but will regard them as the voice of nature, calling upon him to make such thorough reforms as will bring about the only lasting constitution, a lawful constitution based on the principles of freedom. It is always possible that moralists who rule despotically, and are at a loss in practical matters, will come into collision with the rules of political wisdom in many ways, by adopting measures without sufficient deliberation which show themselves afterwards to have been overestimated. When they thus offend against nature, experience must gradually lead them into a better track. But, instead of this being the case, politicians who are fond of moralising do all they can to make moral improvement impossible and to perpetuate violations of law, by extenuating political principles which are antagonistic to the idea of right, on the pretext that human nature is not capable of good, in the sense of the ideal which reason prescribes.
