Each of us has a natural right, from God, to defend his person, his liberty, and his property.

The sort of dependence that results from exchange, i.e., from commercial transactions, is a reciprocal dependence. We cannot be dependent upon a foreigner without his being dependent on us. Now, this is what constitutes the very essence of society. To sever natural interrelations is not to make oneself independent, but to isolate oneself completely.

When goods do not cross borders, soldiers will.

Here I encounter the most popular fallacy of our times. It is not considered sufficient that the law should guarantee to every citizen the free and inoffensive use of his faculties for physical, intellectual and moral self-improvement. Instead, it is demanded that the law should directly extend welfare, education, and morality throughout the nation. This is the seductive lure of socialism. And I repeat: these two uses of the law are in direct contradiction to each other.

The state is the great fictitious entity by which everyone seeks to live at the expense of everyone else.

By virtue of exchange, one man's prosperity is beneficial to all others.

If every person has the right to defend - even by force - his person, his liberty, and his property, then it follows that a group of men have the right to organize and support a common force to protect these rights constantly. Thus, since an individual cannot lawfully use force against the person, liberty, or property of another individual, then the common force - for the same reason - cannot lawfully be used to destroy the person, liberty, or property of individuals or groups.
