The constitution of the United States declares that "no State shall pass any law impairing the obligation of contracts."

All legitimate government is a mutual insurance company, voluntarily agreed upon by the parties to it, for the protection of their rights against wrong-doers. In its voluntary character it is precisely similar to an association for mutual protection against fire or shipwreck.

If the jury have no right to judge of the justice of a law of the government, they plainly can do nothing to protect the people against the oppressions of the government; for there are no oppressions which the government may not authorize by law.

A man is none the less a slave because he is allowed to choose a new master once in a term of years. Neither are a people any the less slaves because permitted periodically to choose new masters.

The commerce of a free people is many times more valuable than that of slaves. Freemen produce and consume vastly more than slaves. They have therefore more to buy and more to sell. Hence the free states have a direct pecuniary interest in the civil freedom of all the other states. Commerce between free and slave states is not reciprocal or equal.

Any government, that is its own judge of, and determines authoritatively for the people, what are its own powers over the people, is an absolute government of course. It has all the powers that it chooses to exercise. There is no other or at least no more accurate definition of a despotism than this.

Doing a thing by law, or according to law, is only carrying the law into execution. And punishing a man by, or according to, the sentence or judgment of his peers, is only carrying that sentence or judgment into execution.
