in giving to those who administer each department, the necessary constitutional means, and personal motives, to resist encroachments of the others. The provision for defence must in this, as in all other cases, be made commensurate to the danger of attack. Ambition must be made to counteract ambition. The interest of the man, must be connected with the constitutional rights of the place. It may be a reflection on human nature, that such devices should be necessary to control the abuses of government. But what is government itself, but the greatest of all reflections on human nature? If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself. A dependence on the people is, no doubt, the primary control on the government; but experience has taught mankind the necessity of auxiliary precautions.
This policy of supplying, by opposite and rival interests, the defect of better motives, might be traced through the whole system of human affairs, private as well as public. We see it particularly displayed in all the subordinate distributions of power; where the constant aim is, to divide and arrange the several offices in such a manner as that each may be a check on the other; that the private interest of every individual may be a centinel over the public rights. These inventions of prudence cannot be less requisite in the distribution of the supreme powers of the state.
But it is not possible to give to each department an equal power of self-defence. In republican government, the legislative authority necessarily predominates. The remedy for this inconveniency is, to divide the legislature into different branches; and to render them, by different modes of election, and different principles of action, as little connected with each other, as the nature of their common functions, and their common depen-
