It may safely be received as an axiom in our political system, that the state governments will in all possible contingencies afford complete security against invasions of the public liberty by the national authority.

It is a general principle of human nature, that a man will be interested in whatever he possesses, in proportion to the firmness or precariousness of the tenure by which he holds it; will be less attached to what he holds by a momentary or uncertain title, than to what he enjoys by a durable or certain title; and, of course, will be willing to risk more for the sake of the one, than for the sake of the other.

The means ought to be proportioned to the end; the persons from whose agency the attainment of any end is expected ought to possess the means by which it is to be attained.

There is no part of the administration of government that requires extensive information and a thorough knowledge of the principles of political economy, so much as the business of taxation. The man who understands those principles best will be least likely to resort to oppressive expedients, or sacrifice any particular class of citizens to the procurement of revenue. It might be demonstrated that the most productive system of finance will always be the least burdensome.

What is the most sacred duty and the greatest source of our security in a Republic? An inviolable respect for the Constitution and Laws.

The awful discretion, which a court of impeachments must necessarily have, to doom to honor or to infamy the most confidential and the most distinguished characters of the community, forbids the commitment of the trust to a small number of persons.

[E]very act of a delegated authority, contrary to the tenor of the commission under which it is exercised, is void. No legislative act, therefore, contrary to the Constitution, can be valid. To deny this, would be to affirm, that the deputy is greater than his principal; that the servant is above his master; that the representatives of the people are superior to the people themselves; that men acting by virtue of powers, may do not only what their powers do not authorize, but what they forbid.
