The contention of the counsel for the state struck at the very root of the judicial system of the Union, with its authority to review state decisions which involved the binding effect of the Federal Constitution and laws: and so to the discussion of this fundamental question Marshall brought his heaviest artillery. In a series of powerful paragraphs he proclaimed the principle of nationalism and the existence of a real union resting on the will and determination of the people:
?That the United States,? he said, ?from, for many, and for most important purposes, a single nation, has not yet been denied. In war, we are one people. In making peace, we are one people. In all commercial regulations, we are one and the same people. In many other respects, the American people are one; and the government which is alone capable of controlling and managing their interests in all these respects, is the government of the Union. It is their government, and in that character they have no other. America has chosen to be, in many respects, and to many purposes, a nation; and for all these purposes, her government is complete; to all these objects, it is competent.?
