The States then being the parties to the constitutional compact, and in their sovereign capacity, it follows of necessity, that there can be no tribunal above their authority, to decide in the last resort, whether the compact made by them be violated; and consequently that as the parties to it, they must themselves decide in the last resort, such questions as may be of sufficient magnitude to require their interposition.

The preservation of a free government requires not merely that the metes and bounds which separate each department of power be invariably maintained; but more especially that neither of them be suffered to overleap the great Barrier which defends the rights of the people. The Rulers who are guilty of such an encroachment, exceed the commission from which they derive their authority and are Tyrants. The people who submit to it are governed by laws made neither by themselves nor by an authority derived from them, and are slaves.

There is not a shadow of right in the general government to intermingle with religion. Its least interference with it would be a most flagrant usurpation.

Democracies have been found incompatible with personal security or the rights of property; and in general been as short in their lives as they have been violent in their death.

In order to judge of the form to be given to this institution the Senate, it will be proper to take a view of the ends to be served by it. These were,first, to protect the people against their rulers, secondly, to protect the people against the transient impressions into which they themselves might be led.

To suppose that any form of government will secure liberty or happiness without any virtue in the people, is a chimerical idea.

I am unable to conceive that the state legislatures which must feel so many motives to watch, and which possess so many means of counteracting the federal legislature, would fail either to detect or to defeat a conspiracy of the latter against the liberties of their common constituencies.
