#That the only security men can have for their political liberty, consists in their keeping their money in their own pockets, until they have assuran… - Lysander Spooner

[I]f there be no such principle as justice, there can be no such acts as crimes; and all the professions of governments, so called, that they exist, either in whole or in part, for the punishment or prevention of crimes, are professions that they exist for the punishment or prevention of what never existed, nor ever can exist.

These conditions are simply these: viz., first, that each man shall do, towards every other, all that justice requires him to do; as, for example, that he shall pay his debts, that he shall return borrowed or stolen property to its owner, and that he shall make reparation for any injury he may have done to the person or property of another. The second condition is, that each man shall abstain from doing to another, anything which justice forbids him to do; as, for example, that he shall abstain from committing theft, robbery, arson, murder, or any other crime against the person or property of another. So long as these conditions are fulfilled, men are at peace, and ought to remain at peace, with each other.

Children learn the fundamental principles of natural law at a very early age. Thus they very early understand that one child must not, without just cause, strike or otherwise hurt, another; that one child must not assume any arbitrary control or domination over another; that one child must not, either by force, deceit, or stealth, obtain possession of anything that belongs to another; that if one child commits any of these wrongs against another, it is not only the right of the injured child to resist, and, if need be, punish the wrongdoer, and compel him to make reparation, but that it is also the right, and the moral duty, of all other children, and all other persons, to assist the injured party in defending his rights, and redressing his wrongs. These are fundamental principles of natural law, which govern the most important transactions of man with man. Yet children learn them earlier than they learn that three and three are six, or five and five ten. Their childish plays, even, could not be carried on without a constant regard to them; and it is equally impossible for persons of any age to live together in peace on any other conditions. It would be no extravagance to say that, in most cases, if not in all, mankind at large, young and old, learn this natural law long before they have learned the meanings of the words by which we describe it. In truth, it would be impossible to make them understand the real meanings of the words, if they did not understand the nature of the thing itself. To make them understand the meanings of the words justice and injustice before knowing the nature of the things themselves, would be as impossible as it would be to make them understand the meanings of the words heat and cold, wet and dry, light and darkness, white and black, one and two, before knowing the nature of the things themselves. Men necessarily must know sentiments and ideas, no less than material things, before they can know the meanings of the words by which we describe them.
