"It is not, perhaps, unreasonable to conclude, that a pure and perfect democracy is a thing not attainable by man, constituted as he is of contending elements of vice and virtue, and ever mainly influenced by the predominant principle of self-interest. It may, indeed, be confidently asserted, that there never was that government called a republic, which was not ultimately ruled by a single will, and, therefore, (however bold may seem the paradox,) virtually and substantially a monarchy."
