"Though the earth, and all inferior creatures be common to all men, yet every man has a property in his own person. This nobody has any right to but himself." -- John Locke, 2nd Treatise of Government, Ch. 5
"The property which every man has in his own labour, as it is the original foundation of all other property, so it is the most sacred and inviolable." -- Adam Smith, The Wealth of Nations, Bk 1, Ch. 10, Pt 2
"The property rights that each citizen has in himself are the foundation of a free society." -- James Bovard, Freedom In Chains, p. 86
"Libertarianism begins with the right of self ownership." -- David Bergland, Libertarianism In One Lesson, p. 35
"There is only one fundamental right (all 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
Since man has to sustain his life by his own effort, the man who has no right to the product of his effort has no means to sustain his life." -- Ayn Rand, Capitalism: The Unknown Ideal, pp. 321-2
"The right of life and liberty--that is to say, the right of the man to himself--is not really one right and the right of property another right. They are two aspects of the same perception--the right of property being but another side, a differently stated expression, of the right of man to himself. The right of life and liberty, and the right of the individual to himself, presupposes and involves the right of property, which is the exclusive right of the individual to the things his exertion has produced." -- Henry George, A Perplexed Philosopher, p. 210
