This theory was, we have seen, a commonplace. The amount of historical authenticity assigned to the contract almost universally presupposed varied enormously. Generally, the weaker a writer’s rational basis, the more he appealed to history⁠—and invented it. It was, therefore, almost inevitable that Rousseau should cast his theory into the contractual form. There were, indeed, writers of his time who laughed at the contract, but they were not writers who constructed a general system of political philosophy. From Cromwell to Montesquieu and Bentham, it was the practically minded man, impatient of unactual hypotheses, who refused to accept the idea of contract. The theorists were as unanimous in its favour as the Victorians were in favour of the “organic” theory. But we, criticising them in the light of later events, are in a better position for estimating the position the Social Contract really took in their political system. We see that Locke’s doctrine of tacit consent made popular control so unreal that he was forced, if the State was to have any hold, to make his contract historical and actual, binding posterity for all time, and that he was also led to admit a quasi-contract between people and government, as a second vindication of popular liberties.
