All restraints upon man's natural liberty, not necessary for the simple maintenance of justice, are of the nature of slavery, and differ from each other only in degree.

Slavery, if it can be legalized at all, can be legalized only by positive legislation. Natural law gives it no aid. Custom imparts to it no legal sanction.

It cannot be said that the Constitution formed 'the people of the United States,' for all time, into a corporation. It does not speak of 'the people' as a corporation, but as individuals. A corporation does not describe itself as 'we,' nor as 'people,' nor as 'ourselves.' Nor does a corporation, in legal language, have any 'posterity.'

Those who are capable of tyranny are capable of perjury to sustain it.

The mental capacity of a person to make reasonable contracts, is the only criterion, by which to determine his legal capacity to make obligatory contracts. And his mental capacity to make reasonable contracts is certainly not to be determined by the fact that he is, or is not, twenty-one years of age.

No man can delegate,... any right of arbitrary dominion over a 3rd person; for that would imply a right in the 1st person, not only to make the 3rd person his slave, but also a right to dispose of him as a slave to still other persons. Any contract to do this is necessarily a criminal one...To call such a contract a “constitution” does not at all lessen its criminality, or add to its validity.

For everybody has a natural right not only to defend his own person and property against aggressors, but also to go to the assistance and defence of everybody else, whose person or property is invaded. The natural right of each individual to defend his own person and property against an aggressor, and to go to the assistance and defence of every one else whose person or property is invaded, is a right without which men could not exist on earth.
