James Madison states, that the philosophy of American republicanism admits the existence of qualities in human nature in a higher degree, i.e., built on a spiritual Ideal of man’s nature.
“As there is a degree of depravity in mankind which requires a certain degree of circumspection and distrust: So there are other qualities in human nature, which justify a certain portion of esteem and confidence. Republican government (that of a Republic) presupposes the existence of these qualities in a higher degree than any other form. Were the pictures which have been drawn by the political jealousy of some among us, faithful likenesses of the human character, the inference would be that there is not sufficient virtue among men for self government; and that nothing less than the chains of despotism can restrain them from destroying and devouring one another.” (James Madison, Federalist Papers, no. 55, Fed. 13., 1788)
