1. The laws of any nation are the rules by which it is governed, a violation of which renders the offender liable to the infliction of certain penalties. These laws, in many nations, are carefully and systematically arranged in the beginning, as in the United States; in others, as in England, they are gradually produced, the course taken in dealing with the first of a class of similar cases furnishing a precedent that is equal in force to a general law. 2. From very early times the different nations who had[592] intercourse with each other began to follow certain rules, which commonly originated in the mode last mentioned above; and many of them became generally recognized as the proper guide in international intercourse. These customs came, at length, to be called the Law of Nations. Writers of eminence carefully investigated them, and studied the principles on which they were founded. These writers are held to be authorities as to this law, and the principles they have laid down are generally acknowledged, by civilized nations in modern times, as the standard of International Law.
3. There is no possibility, in the present state of the world, of organizing a tribunal with authority to impose penalties for violations of this law by individual nations; though it is to be hoped that may some time be the case. The only representative of such a tribunal is the general opinion of the civilized world; and nations must, themselves, act as supreme judges and executors of the law as it applies (or as they choose to hold it as applying) to their disputes. When they cannot come to an agreement with their adversaries, they commonly Declare War, and endeavor to right themselves by force.
4. This is not, by any means, an equitable or satisfactory way of avenging wrongs. The aggressor may be the strongest; and the offense, in that case, will be greatly increased. It causes the penalty, in any case, to fall very heavily on many innocent heads, and produces lamentable and wide-spread desolation. Yet it is sometimes better than tame submission; and the right to make war when grievous wrong has been suffered, or indignity offered to the national honor, is recognized by the Law of Nations; and certain rules are applied by it as a guide in honorable warfare. There is nothing but self-respect, and respect for the opinions of the civilized world, to keep belligerent nations within the limits of these rules. They are, however, continually becoming better defined, and Public Opinion has more and more weight in each succeeding generation.
