Definition International law may be considered from two points of view, viz.: (a) From the philosophical point of view, as setting forth the rules and principles which ought to be observed in interstate relations. Philosophical and scientific standpoints. (b) From the scientific point of view, as setting forth the rules and principles which are generally observed in interstate relations. Wheaton's definition is (Wheaton D., 23): "International law, as understood among civilized nations, may be defined as consisting of those rules of conduct which reason deduces, as consonant to justice, from the nature of the society existing among independent nations; with such definitions and modifications as may be established by general consent." (See also 1 Pradier-Fodéré, pp. 8, 41.) Early writers treated especially of those principles which ought to be observed in interstate action, and the wealth of quotation and testimony introduced to establish the validity of principles now considered almost axiomatic, is overwhelming. In the days of Ayala, Brunus, Gentilis, Grotius, and Pufendorf, all the argument possible was needed to bring states to submit to these principles. The conditions and relations of states have so changed that at the present time a body of fairly established rules and principles is observed in interstate action, and forms the subject-matter of international law.1 2. Divisions International law is usually divided into: (a) Public international law, which treats of the rules and principles which are generally observed in interstate action, and Public and (b) Private international law, which treats of the rules and principles which are observed in cases of conprivate inter- flict of jurisdiction in regard to private rights. These cases are not properly international, and a better term for this branch of knowledge is that given by Judge Story, "The Conflict of Laws." 2 national law. International law, in the true sense, deals only with state affairs. 3. Scope International law is generally observed by civilized states; some states, even before they were fully opened to western civilization, professed to observe its rules. The expansion of commerce and trade, the introduction of new and rapid means of communication, the diffusion of knowledge through books and travel, the establishment of permanent embassies, the making of many treaties containing the same general provisions, and the whole movement of modern civilization toward unifying the interests of states, has rapidly enlarged the range of international action and the scope of international law. Civilized states, so far as possible, observe the rules 1 Hall, introductory chapter. 'Dicey, "Conflict of Laws," English, with notes of American cases, by J. B. Moore.

International law covers all the relations into which civilized states may come, both peaceful and hostile. In general, its scope should not be extended so as to interfere with domestic affairs or to limit domestic jurisdiction, though it does often limit the economic and commercial action of a given state, and determine to some extent its policy. |
