Vattel, in his chapter on the general principles of the laws of nations, section 15th, tells us, that "nations being free and independent of each other in the same manner that men are naturally free and independent, the second general law of their society is, that each nation should be left in the peaceable enjoyment of that liberty which she inherits from nature." "The natural society of nations," says this writer, "cannot subsist unless the natural rights of each be respected." In section 16th he says, "as a consequence of that liberty and independence, it exclusively belongs to each nation to form her own judgment of what her conscience prescribes for her--of what it is proper or improper for her to do; and of course it rests solely with her to examine and determine whether she can perform any office for another nation without neglecting the duty she owes to herself. In all cases, therefore, in which a nation has the right of judging what her duty requires, no other nation can compel her to act in such or such a particular manner, for any attempt at such compulsion would be an infringement on the liberty of nations." Again, in section 18th, of the same chapter, "nations composed of men, and considered as so many free persons living together in a state of nature, are naturally equal, and inherit from nature the same obligations and rights. Power or weakness does not produce any difference. A small republic is no less a sovereign state than the most powerful kingdom." So, in section 20: "A nation, then, is mistress of her own actions, so long as they do not affect the proper and _perfect rights_ of any other nation--so long as she is only _internally_ bound, and does not lie under any _external_ and _perfect_ obligation. If she makes an ill use of her liberty, she is guilty of a breach of duty; but other nations are bound to acquiesce in her conduct, since they have no right to dictate to her. Since nations are _free_, _independent_, and _equal_, and since each possesses the right of judging, according to the dictates of her conscience, what conduct she is to pursue, in order to fulfil her duties, the effect of the whole is to produce, at least externally, in the eyes of mankind, a perfect equality of rights between nations, in the administration of their affairs, and in the pursuit of their pretensions, without regard to the intrinsic justice of their conduct, of which others have no right to form a definitive judgment."
