I should . . . prefer swallowing one incomprehensibility rather than two. It requires one effort only to admit the single incomprehensibility of matter endowed with thought, and two to believe, first that of an existence called spirit, of which we have neither evidence nor idea, and then secondly how that spirit, which has neither extension nor solidity, can put material organs into motion.

We hold these truths to be self-evident: that all men are created equal; that they are endowed by their Creator with certain unalienable rights; that among these are life, liberty, and the pursuit of happiness.

[T]o preserve the republican form and principles of our Constitution and cleave to the salutary distribution of powers which that [the Constitution] has established . . . are the two sheet anchors of our Union. If driven from either, we shall be in danger of foundering.

We shall divert through our own Country a branch of commerce which the European States have thought worthy of the most important struggles and sacrifices, and in the event of peace on terms which have been contemplated by some powers we shall form to the American union a barrier against the dangerous extension of the British Province of Canada and add to the Empire of liberty an extensive and fertile Country thereby converting dangerous Enemies into valuable friends.

The most effective means of preventing tyranny is to illuminate, as far as practicable, the minds of the people at large, and more especially to give them knowledge of those facts.

An honest man can feel no pleasure in the exercise of power over his fellow citizens.
