There was every motive on their part to give point and clearness to every restriction of national power; for they well knew, that the national government would be more endangered in its adoption by its supposed strength, than by its weakness. It is inconceivable, that they should have disguised a restriction upon its powers under the form of a grant of power. They would have sought other terms, and have imposed the restraint by negatives.[1] And what is equally strong, no one, in or out of the state conventions, at the time when the constitution was put upon its deliverance before the people, ever dreamed of, or suggested, that it contained a restriction of power. The whole argument on each side, of attack and of defence, gave it the positive form of an express power, and not of an express restriction.

The motive for its insertion doubtless was, the desire to remove all possible doubt respecting the right to legislate on that vast mass of incidental powers, which must be involved in the constitution, if that instrument be not a splendid pageant, or a delusive phantom of sovereignty. Let the end be legitimate; let it be within the scope of the constitution; and all means, which are appropriate, which are- ↑ M'Culloch v. Maryland, 4 Wheat. R. 420.
