To listen well is as powerful a means of communication and influence as to talk well

The particular phraseology of the Constitution of the United States confirms and strengthens the principle, supposed to be essential to all written constitutions, that a law repugnant to the Constitution is void; and that courts, as well as other departments, are bound by that instrument.

To obtain a just compromise, concession must not only mutual-it must be equal also....There can be no hope that either will yield more than it gets in return.

The government of the United States has been emphatically termed a government of laws, and not of men. It will certainly cease to deserve this high appellation, if the laws furnish no remedy for the violation of a vested legal right.

State inspection laws, health laws, and laws for regulating the internal commerce of a State, and those which respect turnpike roads, ferries, &c. are not within the power granted to Congress. ... Inspection laws, quarantine laws, health laws of every description, as well as laws for regulating the internal commerce of a State, and those which respect turnpike roads, ferries, &c., are component parts of this mass. No direct general power over these objects is granted to Congress, and, consequently, they remain subject to State legislation.

That the people have an original right to establish, for their future government, such principles as, in their opinion, shall most conduce to their own happiness, is the basis, on which the whole American fabric has been erected.... The principles, therefore, so established, are deemed fundamental. And as the authority, from which they proceed, is supreme ... they are designed to be permanent.... The powers of the legislature are defined, and limited; and that those limits may not be mistaken, or forgotten, the constitution is written.
