Man's Rights

. . . the source of rights is man's nature.
["Man's Rights," The Virtue of Selfishness]

. . .—the source of man's rights is not divine law or congressional law, but the law of identity. A is A—and Man is Man. Rights are conditions of existence required by man's nature for his proper survival. If man is to live on earth, it is right for him to use his mind, it is right to act on his own free judgment, it is right to work for his values and to keep the product of his work. If life on earth is his purpose, he has a right to live as a rational being: nature forbids him the irrational.
["This Is John Galt Speaking," Atlas Shrugged]

A "right" is a moral principle defining and sanctioning a man's freedom of action in a social context. There is only one fundamental right (all the others are its consequences or corollaries): a man's right to his own life. Life is a process of self-sustaining and self-generated action; the right to life means the right to engage in self-sustaining and self-generated action—which means: the freedom to take all the actions required by the nature of a rational being for the support, the furtherance, the fulfillment and the enjoyment of his own life. (Such is the meaning of the right to life, liberty and the pursuit of happiness.)

The concept of a "right" pertains only to action—specifically, to freedom of action. It means freedom from physical compulsion, coercion or interference by other men.

Thus, for every individual, a right is the moral sanction of a positive—of his freedom to act on his own judgment, for his own goals, by his own voluntary, uncoerced choice. As to his neighbors, his rights impose no obligations on them except of a negative kind: to abstain from violating his rights.
