Excerpt:

“If we resort for a criterion to the different principles on which different forms of government are established, we may define a republic to be, or at least may bestow that name on, a government which derives all its powers directly or indirectly from the great body of the people, and is administered by persons holding their offices during pleasure, for a limited period, or during good behavior. It is ESSENTIAL to such a government that it be derived from the great body of the society, not from an inconsiderable proportion, or a favored class of it; otherwise a handful of tyrannical nobles, exercising their oppressions by a delegation of their powers, might aspire to the rank of republicans, and claim for their government the honorable title of republic. It is SUFFICIENT for such a government that the persons administering it be appointed, either directly or indirectly, by the people; and that they hold their appointments by either of the tenures just specified; otherwise every government in the United States, as well as every other popular government that has been or can be well organized or well executed, would be degraded from the republican character. According to the constitution of every State in the Union, some or other of the officers of government are appointed indirectly only by the people. According to most of them, the chief magistrate himself is so appointed. And according to one, this mode of appointment is extended to one of the co-ordinate branches of the legislature. According to all the constitutions, also, the tenure of the highest offices is extended to a definite period, and in many instances, both within the legislative and executive departments, to a period of years. According to the provisions of most of the constitutions, again, as well as according to the most respectable and received opinions on the subject, the members of the judiciary department are to retain their offices by the firm tenure of good behavior.”
