No man may initiate the use of physical force against others. No man-or group or society or government-has the right to assume the role of a criminal and initiate the use of physical compulsion against any man. Men have the right to use physical force only in retaliation and only against those who initiate its use. The ethical principle involved is simple and clear-cut: it is the difference between murder and self-defense.

Potentially, a government is the most dangerous threat to man's rights: it holds a legal monopoly on the use of physical force against legally disarmed victims.

Money is a tool of exchange, which can't exist unless there are goods produced and men able to produce them. Money is the material shape of the principle that men who wish to deal with one another must deal by trade and give value for value.

Any material element or resource which, in order to become of use or value to men, requires the application of human knowledge and effort, should be private property-by the right of those who apply the knowledge and effort.

Hence the sterile, uninspiring futility of a great many theoretical discussions of ethics, and the resentment which many people feel towards such discussions: moral principles remain in their minds as floating abstractions, offering them a goal they cannot grasp and demanding that they reshape their souls in its image, thus leaving them with a burden of undefinable moral guilt.

Kant is the most evil man in mankind's history.

A free mind and a free market are corollaries.
