"The first of these purposes, which alone can have an uninterrupted claim upon us, is sufficiently answered by an association of such an extent as to afford room for the institution of a jury, to decide upon the offences of individuals within the community, and upon the questions and controversies respecting property which may chance to arise."[75] This jury would decide not according to any system of law, but according to reason.[76]--"It might be easy indeed for an offender to escape from the limits of so petty a jurisdiction; and it might seem necessary at first that the neighboring parishes or jurisdictions should be governed in a similar manner, or at least should be willing, whatever was their form of government, to co-operate with us in the removal or reformation of an offender whose present habits were alike injurious to us and to them. But there will be no need of any express compact, and still less of any common centre of authority, for this purpose. General justice and mutual interest are found more capable of binding men than signatures and seals."[77] The second function would present itself to us only from time to time. "However irrational might be the controversy of parish with parish in such a state of society, it would not be the less possible. Such emergencies can only be provided against by the concert of several districts, declaring and, if needful, enforcing the dictates of justice."[78] Foreign invasions too would make such a concert necessary, and would to this extent resemble those controversies.[79] Therefore it would be "necessary upon certain occasions to have recourse to national assemblies, or in other words assemblies instituted for the joint purpose of adjusting the differences between district and district, and of consulting respecting the best mode of repelling foreign invasion."[80]--But they "ought to be employed as sparingly as the nature of the case will admit."[81] For, in the first place, the decision is given by the number of votes, and "is determined, at best, by the weakest heads in the assembly, but, as it not less frequently happens, by the most corrupt and dishonorable intentions."[82] In the second place, as a rule the members are guided in their decisions by all sorts of external reasons, and not solely by the results of their free reflection.[83] In the third place, they are forced to waste their strength on petty matters, while they cannot possibly let themselves be quietly influenced by argument.[84] Therefore national assemblies should "either never be elected but upon extraordinary emergencies, like the dictator of the ancient Romans, or else sit periodically, one day for example in a year, with a power of continuing their sessions within a certain limit. The former is greatly to be preferred."[85]
