In 1908 the second volume of the American Journal of International Law featured a piece by Lassa Oppenheim entitled The Science of International Law: Its Tasks and Method. Oppenheim began his article by noting, apparently with some approval, that the first volume of AJIL, stacked with articles only by Americans, had “shown to the world that America is able to foster the science of international law without being dependent upon the assistance of foreign contributors.” Concerned, however, that students were “at first frequently quite helpless for want of method [and] mostly plunge into their work without a proper knowledge of the task of our science, without knowing how to make use of the assertions of authorities, and without the proper views for the valuation and appreciation of the material at hand,” Oppenheim sought to bring “the task and the method of this our science into discussion in this Journal.” What followed was a comprehensive exposition of his views on the purposes of international law and the methods available to lawyers and scholars for approaching the problems they face.

4 The AJIL is not the first periodical of its kind to embrace the need for such an understanding. Our friends at the European Journal of International Law stated at the time of its founding a decade ago that they would devote pages to the intellectual legacies of the great European scholars, and their collections of essays on Friedmann, Verdross, Lauterpacht and Kelsen have been exemplary in this regard.

6 According to Kelsen:
[U]ne analyse juridique rigoureuse est indispensable pour atteindre I’amélioration si désirable de la technique du droit international. C’est justement pour remplir cette tâche de la politique du droit qu’une théorie pure du droit est nécessaire, de même qu’il n’y a pas de médecine scientifique sans biologie, pas de technique sans physique.

9 For one theory that nonetheless disguises itself as a method, see Martin Bos, A Methodology of International Law (1984); and id. at 2 (“methodology … in fact is a phenomenology”).
10 See, e.g., Shabtai Rosenne, Practice and Methods of International Law (1984).
11 The distinction between a legal theory—the conceptual framework—and a legal method is not the same as the distinction between “theory” and “practice.” At least one of the methods presented in this symposium rejects such a distinction on the ground that “theory is practice” and vice versa. Its point is rather that a method entails the application of more abstract concepts to more concrete problems.

For instance, common Article 3 includes the following provision:
[T]he following acts are and shall remain prohibited at any time and in any place whatsoever with respect to the above-mentioned persons [persons taking no active part in the hostilities]:
(a) violence to life and person, in particular murder of all kinds, mutilation, cruel treatment and torture;
(b) taking of hostages;
(c) outrages upon personal dignity, in particular humiliating and degrading treatment;
(d) the passing of sentences and the carrying out of executions without previous judgment pronounced by a regularly constituted court, affording all the judicial guarantees which are recognized as indispensable by civilized peoples.
22 See, e.g., the list in Geneva Convention IV, supra note 21, Art. 147:
wilful killing, torture or inhuman treatment, including biological experiments, wilfully causing great suffering or serious injury to body or health, unlawful deportation or transfer or unlawful confinement of a protected person, compelling a protected person to serve in the forces of a hostile Power, or wilfully depriving a protected person of the rights of fair and regular trial prescribed in the present Convention, taking of hostages and extensive destruction and appropriation of property, not justified by military necessity and carried out unlawfully and wantonly.

S/INF/50 (1994), reprinted in 33 ILM 1602 (1994). Equally important, though less relevant for the symposium, the Statute of the Rwanda Tribunal defines crimes against humanity without any reference to armed conflict (interstate or internal) at all, thus confirming the severance of the nexus first included in the Charter of the International Military Tribunal at Nuremberg.
