The case is precisely the same with the political or civil duty of allegiance as with the natural duties of justice and fidelity. Our primary instincts lead us either to indulge ourselves in unlimited liberty or to seek dominion over others; and it is this reflection only which engages us to sacrifice such strong passions to the interests of peace and order. A very small degree of experience and observation suffices to teach us that society cannot possibly be maintained without the authority of magistrates, and that this authority must soon fall into contempt where exact obedience is not paid to it. The observation of these general and {p187} obvious interests is the source of all allegiance, and of that moral obligation which we attribute to it.
What necessity, therefore, is there to found the duty of allegiance or obedience to magistrates on that of fidelity or a regard to promises, and to suppose that it is the consent of each individual which subjects him to government, when it appears that both allegiance and fidelity stand precisely on the same foundation, and are both submitted to by mankind, on account of the apparent interests and necessities of human society? We are bound to obey our sovereign, it is said, because we have given a tacit promise to that purpose. But why are we bound to observe our promise? It must here be asserted that the commerce and intercourse of mankind, which are of such mighty advantage, can have no security where men pay no regard to their engagements. In like manner may it be said that men could not live at all in society, at least in a civilized society, without laws and magistrates and judges to prevent the encroachments of the strong upon the weak, of the violent upon the just and equitable. The obligation to allegiance being of like force and authority with the obligation to fidelity, we gain nothing by resolving the one into the other. The general interests or necessities of society are sufficient to establish both.
