Quotes from the same author

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.
 Lysander Spooner
If a jury have not the right to judge between the government and those who disobey its laws, and resist its oppressions, the government is absolute, and the people, legally speaking, are slaves.
 Lysander Spooner
The right of absolute and irresponsible dominion is the right of property, and the right of property is the right of absolute, irresponsible dominion. The two are identical; the one necessarily implying the other.
 Lysander Spooner
For a government to declare a vice to be a crime, and to punish it as such, is an attempt to falsify the very nature of things. It is as absurd as it would be to declare truth to be a falsehood, or falsehood a truth.
 Lysander Spooner
The apology, that is constantly put forth for the injustice of government, viz., that a man must consent to give up some of his rights, in order to have his other rights protected - involves a palpable absurdity, both legally and politically.
