Do not open your mouth to tell me that your mind has convinced you of your right to force my mind. Force and mind are opposites. Morality ends where a gun begins.

Get the hell out of my way!

When you force a man to act against his own choice and judgment, it's his thinking that you want him to suspend.

Whatever may be open to disagreement, there is one act of evil that may not, the act that no man may commit against others and no man may sanction or forgive. So long as men desire to live together, no man may initiate—do you hear me? no man may start—the use of physical force against others.

The [U.S.] Constitution is a limitation on the government, not on private individuals ... it does not prescribe the conduct of private individuals, only the conduct of the government ... it is not a charter for government power, but a charter of the citizen's protection against the government.

To know one's own desires, their meaning and their costs requires the highest human virtue: rationality.

Rationality is the recognition of the fact that nothing can alter the truth and nothing can take precedence over that act of perceiving it.
