Book Description

Washington, D.C.: United States Government Printing Office, 1957. vi, 275 pp. Reprinted 2001, 2011. The noted jurist Hans Kelsen advances his theory that collective security is "...an essential function of law, national as well as international, and that, therefore, there exists an intrinsic connection between international security and international law; in other terms, that collective security of the state is, just as collective security of the individual within the state, by its very nature a legal problem." Foreword p. ii. "Professor Kelsen's high standing as a scholar is sufficient to commend in advance any volume that comes from his pen. But in this case he has chosen a subject that will at once challenge attention. The main function of the volume, in the words of the author, 'is to show that collective security is an essential function of law,' that it is 'by its very nature a legal problem.' A generation ago there were many in high places to contest the thesis. Today the bitter lesson of two world wars has established the principle for practical purposes, in spite of the difficulty of putting it into practice. But the legal aspects of the thesis remain to be clarified, and this is what Professor Kelsen does with all his power of legal analysis and systematic presentation. (...) [We] must be grateful for what we are given, an acute analysis of a fundamental principle, the applications of which we can make from our own knowledge of recent history." --C. G. Fenwick, American Journal of International Law 52 (1958) 811.
