M'Culloch v. Maryland · ¶40

We admit, as all must admit, that the powers of the government are limited, and that its limits ¿re not to be transcended. But wé.think the sound construction of the constitution must allow-to the national legislature that discretion,- with respect to the means by which the powers it confers are to be carried into execution, which will enable that body to perform the high duties assigned to it, -in the manner most beneficial to the people. Let the end be legitimate, let it be within the scope of the constitution, and all means which are appropriate, which are plainly adapted to that end, which are not prohibited, but consist with the letter and spirit of the constitution, are constitutional.
