But the defects of the Confederation need not be detailed. Under its operation we could scarcely be called a nation. We had neither prosperity at home nor consideration abroad. This state of things could not be endured, and our present happy Constitution was formed, but formed in vain, if this fatal doctrine prevails. It was formed for important objects that are announced in the preamble made in the name and by the authority of the people of the United States, whose delegates framed, and whose conventions approved, it. The most important among these objects, that which is placed first in rank, on which all the others rest, is "_to form a more perfect Union_." Now, it is possible that, even if there were no express provision giving supremacy to the Constitution and laws of the United States over those of the States, it can be conceived that an instrument made for the purpose of "_forming a more perfect Union_" than that of the Confederation, could be so constructed by the assembled wisdom of our country as to substitute for that confederation a form of government, dependent for its existence on the local interest, the party spirit of a State, or of a prevailing faction in a State? Every man, of plain, unsophisticated understanding, who hears the question, will give such an answer as will preserve the Union. Metaphysical subtlety, in pursuit of an impracticable theory, could alone have devised one that is calculated to destroy it. I consider, then, the power to annul a law of the United States, assumed by one State, _incompatible with the existence of the Union, contradicted expressly by the letter of the Constitution, unauthorized by its spirit, inconsistent with every principle on which it was founded, and destructive of the great object for which it was formed_. After this general view of the leading principle, we must examine the particular application of it which is made in the ordinance.
