Abel P. Upshur,
A Brief Enquiry into the Nature and Character of our Federal Government
(1863 (org. 1840))
“ The Federal Government is the creature of the States. It is not a party to the Constitution, but the result of it—the creation of that agreement which was made by the States as parties. It is a mere agent, entrusted with limited powers for certain specific objects; which powers and objects are enumerated in the Constitution. Shall the agent be permitted to judge of the extent of his own powers, without reference to his constituent? ”
