It is not true then that such prescription rises even at a time beyond the period of the memory of man. For since the law absolutely denies all prescription, not even immemorial time has any effect on the question; that is, as Felinus[121] says, things imprescriptible by nature do not become prescriptible by the mere efflux of immemorial time. Balbus admits the truth of these arguments,[122] but says that the opinion of Angeli is to be accepted on the ground that time immemorial is believed to have the same validity as prerogative for setting up a title, since a perfect title is presumed from such efflux of time. Hence it appears that the jurists thought if some part of a state, say of the Roman empire for example, at a period before the memory of man had exercised such a right, that a title by prescription would - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - concessio praeiisset. Quare cum nemo sit dominus totius generis humani, qui ius illud adversus homines omnes homini, aut populo alicui potuisset concedere, sublato illo colore, necesse est etiam praescriptionem interimi. Et sic ex illorum etiam sententia inter reges aut populos liberos prodesse nihil potest lapsus infiniti temporis. Vanissimum autem et illud est quod Angelus docuit, etiamsi ad dominium praescriptio proficere non potest, tamen dandam esse possidenti exceptionem. Nam Papinianus disertis verbis exceptionem negat:[123a] et aliter non potuit sentire, cum ipsius saeculo praescriptio nihil esset aliud quam exceptio. Verum igitur est quod et leges Hispanicae exprimunt[124a] in his rebus quae communi hominum usui sunt attributae, nullius omnino temporis praescriptionem procedere, cuius definitionis illa praeter ceteras ratio reddi potest, quod qui re communi utitur, ut communi uti videtur, non autem iure proprio, et ita praescribere non magis quam fructuarius potest vitio possessionis.[125a] Altera haec etiam non contemnenda est, quod in praescriptione temporis cuius memoria non exstat, quamvis titulus et bona fides praesumantur, tamen si re ipsa appareat titulum omnino nullum dari posse, et sic manifesta sit fides mala, quae in populo maxime quasi uno corpore perpetua esse - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - have to be admitted on that ground, exactly as if there had been a previous grant from a Prince. But inasmuch as there is no one who is sovereign of the whole human race with competence to grant to any man or to any nation such a right against all other men, with the annihilation of that pretext, title by prescription is also necessarily destroyed. Therefore the opinion of the jurists is that not even an infinite lapse of time is able to set up a right as between kings or independent nations.
