There were only two ways, by which such an event could have been produced, by compulsion or consent. When mankind first saw the necessity of government, it is probable that many had conceived the desire of ruling. To be placed in a new situation, to be taken from the common herd, to be the first, distinguished among men, were thoughts, that must have had their charms. Let us suppose then, that these thoughts had worked so unusually on the passions of any particular individual, as to have driven him to the extravagant design of obtaining the preeminence by force. How could his design have been accomplished? How could he forcibly have usurped the jurisdiction at a time, when, all being equally free, there was not a single person, whose assistance he could command? Add to this, that, in a state of universal liberty, force had been repaid by force, and the attempt had been fatal to the usurper.
As empire then could never have been gained at first by compulsion, so it could only have been obtained by consent; and as men were then going to make an important sacrifice, for the sake of their mutual happiness, so he alone could have obtained it, (not whose ambition had greatly distinguished him from the rest) but in whose wisdom, justice, prudence, and virtue, the whole community could confide.
To confirm this reasoning, we shall appeal, as before, to facts; and shall consult therefore the history of those nations, which having just left their former state of independent society, were the very people that established subordination and government.
The commentaries of Caesar afford us the following accounts of the ancient Gauls. When any of their kings, either by death, or deposition, made a vacancy in the regal office, the whole nation was immediately convened for the appointment of a successor. In these national conventions were the regal offices conferred. Every individual had a voice on the occasion, and every individual was free. The person upon whom the general approbation appeared to fall, was immediately advanced to pre-eminence in the state. He was uniformly one, whose actions had made him eminent; whose conduct had gained him previous applause; whose valour the very assembly, that elected him, had themselves witnessed in the field; whose prudence, wisdom and justice, having rendered him signally serviceable, had endeared him to his tribe. For this reason, their kingdoms were not hereditary; the son did not always inherit the virtues of the sire; and they were determined that he alone should possess authority, in whose virtues they could confide. Nor was this all. So sensible were they of the important sacrifice they had made; so extremely jealous even of the name of superiority and power, that they limited, by a variety of laws, the authority of the very person, whom they had just elected, from a confidence of his integrity; Ambiorix himself confessing, “that his people had as much power over him, as he could possibly have over his people.”
