Says Mirabeau, in his beautiful essay on "Despotism," "We can destroy the life of a man for a frightful crime; but that is not to appropriate my existence when it is forced from me. Consider, upon this subject, how absurd is the opinion of the pretended philosophers who have established force as title; who have set up a right of conquest, and recognized to the conquerors the legitimate power to grant life or put to death. "It is not true that the right of life and death, exercised by a man upon another man, has ever been anything else than an act of frenzy; for your enemy reduced to slavery can be yet useful to you, provided you preserve his life,--and this is less than the right that he has upon you, and the relation which binds you together; but the massacre of a man is nothing more than to dishonor and disgust humanity, * * * the right of life and death, * * * and what other has the Creator to exercise over our existence? "From man to man the rights then are always respective. Personal propriety cannot surrender itself, liberty cannot alienate itself. This first gift of nature is imprescriptible; and men, even in their delirium, cannot renounce it." III. "Opinion makes the law." If human laws are uncertain and contradictory, it is not the fault of nature, since man has invented or discovered rules in the science of physics which are constant and invariable, like those of geometry and chemistry. Whatever renders the laws of society invariable, inoperative, is due to the inherent weakness of their basis, and not to the eternal principles of truth and justice. All human laws must be founded on that fundamental and immutable law of nature, "Whatsoever ye would that men should do to you, do ye even so to them." This precept of divine origin is the great balance of the human mind; and it is the secret spring of the progress of nations, as well as the social development of individuals: for without this principle the world would be nothing but a vast arena, in which all classes of people would be arrayed against each other in deadly conflict; impelled by the force of passion and appetite, error and prejudice would soon banish the influence of truth and reason. The weaker families would soon be consumed by the stronger in the wars of avarice and religion. "The laws of nature," writes M. Regis, "are the dictates of right reason, which teach every man how he is to use his natural right; and the laws of nations are the dictates, in like manner, of right reason, which teach every state how to act and behave themselves toward others."
