Your own reason is the only oracle given to you by God.

But, you may ask, if the two departments [i.e., federal and state] should claim each the same subject of power, where is the common umpire to decide ultimately between them? In cases of little importance or urgency, the prudence of both parties will keep them aloof from the questionable ground; but if it can neither be avoided nor compromised, a convention of the States must be called to ascribe the doubtful power to that department which they may think best.

In truth, politeness is artificial good humor, it covers the natural want of it, and ends by rendering habitual a substitute nearly equivalent to the real virtue.

Congress has not unlimited powers to provide for the general welfare, but only those specifically enumerated.

The construction applied . . . to those parts of the Constitution of the United States which delegate Congress a power . . . ought not to be construed as themselves to give unlimited powers, nor a part to be so taken as to destroy the whole residue of that instrument.

Experience has already shown that the impeachment the Constitution has provided is not even a scarecrow.

I join you therefore in branding as cowardly the idea that the human mind is incapable of further advances.
