Finally, as to the time required for prescription, it would be superfluous to show that the right of property in general cannot be acquired by simple possession for ten, twenty, a hundred, a thousand, or one hundred thousand years; and that, so long as there exists a human head capable of understanding and combating the right of property, this right will never be prescribed. For principles of jurisprudence and axioms of reason are different from accidental and contingent facts. One man's possession can prescribe against another man's possession; but just as the possessor cannot prescribe against himself, so reason has always the faculty of change and reformation. Past error is not binding on the future. Reason is always the same eternal force. The institution of property, the work of ignorant reason, may be abrogated by a more enlightened reason. Consequently, property cannot be established by prescription. This is so certain and so true, that on it rests the maxim that in the matter of prescription a violation of right goes for nothing. But I should be recreant to my method, and the reader would have the right to accuse me of charlatanism and bad faith, if I had nothing further to advance concerning prescription. I showed, in the first place, that appropriation of land is illegal; and that, supposing it to be legal, it must be accompanied by equality of property. I have shown, in the second place, that universal consent proves nothing in favor of property; and that, if it proves any thing, it proves equality of property. I have yet to show that prescription, if admissible at all, presupposes equality of property. This demonstration will be neither long nor difficult. I need only to call attention to the reasons why prescription was introduced. "Prescription," says Dunod, "seems repugnant to natural equity, which permits no one either to deprive another of his possessions without his knowledge and consent, or to enrich himself at another's expense. But as it might often happen, in the absence of prescription, that one who had honestly earned would be ousted after long possession; and even that he who had received a thing from its rightful owner, or who had been legitimately relieved from all obligations, would, on losing his title, be liable to be dispossessed or subjected again,--the public welfare demanded that a term should be fixed, after the expiration of which no one should be allowed to disturb actual possessors, or reassert rights too long neglected.... The civil law, in regulating prescription, has aimed, then, only to perfect natural law, and to supplement the law of nations; and as it is founded on the public good, which should always be considered before individual welfare,--_bono publico usucapio introducta est_,--it should be regarded with favor, provided the conditions required by the law are fulfilled."
