It is also true that it is impossible to be too careful to observe, in such cases, all the formalities necessary to distinguish a regular and legitimate act from a seditious tumult, and the will of a whole people from the clamour of a faction.

From this obligation the prince derives a great advantage in preserving his power despite the people, without it being possible to say he has usurped it; for, seeming to avail himself only of his rights, he finds it very easy to extend them, and to prevent, under the pretext of keeping the peace, assemblies that are destined to the reestablishment of order; with the result that he takes advantage of a silence he does not allow to be broken, or of irregularities he causes to be committed, to assume that he has the support of those whom fear prevents from speaking, and to punish those who dare to speak. Thus it was that the decemvirs, first elected for one year and then kept on in office for a second, tried to perpetuate their power by forbidding the comitia to assemble; and by this easy method every government in the world, once clothed with the public power, sooner or later usurps the sovereign authority.
