[T]he delegation of the government, in [a republic], to a small number of citizens elected by the rest . . . [is] to refine and enlarge the public views by passing them through the medium of a chosen body of citizens, whose wisdom may best discern the true interest of their country and whose patriotism and love of justice will be least likely to sacrifice it to temporary or partial considerations.
James MadisonIf 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.
James MadisonIt may be considered as an objection inherent in the principle, that as every appeal to the people would carry an implication of some defect in the government, frequent appeals would in great measure deprive the government of that veneration which time bestows on every thing, and without which perhaps the wisest and freest governments would not possess the requisite stability . . . a constitutional road to the decision of the people ought to be marked out and kept open, for certain great and extraordinary occasions
James MadisonAs the people are the only legitimate fountain of power, and it is from them that the constitutional charter, under which the several branches of government hold their power, is derived, it seems strictly consonant to the republican theory, to recur to the same original authority, not only whenever it may be necessary to enlarge, diminish, or new-model the powers of the government, but also whenever any one of the departments may commit encroachments on the chartered authorities of the others.
