The Conference on "Ethical values in international decision­ making" was held by the Grotius Seminarium in the period June 16-20, 1958 at the Institute of Social Studies in the Hague. At that time, a number of papers were distributed to the par­ ticipants while -after the Conference -two brief reports appeared in "De Internationale Spectator" (1958, I, p. 426-435) and in "Research and Education in the Netherlands" (September 1958, Vol. II, no. 3, p. 18-21). As considerable time has elapsed since, this Booklet does not give a "report" on the Conference, but rather it attempts to recapture its spirit and to elaborate some of the problems which were discussed. The introductory "Remarks" do this in an indi­ vidualistic manner for which the author alone is responsible, but it is hoped that this way of presenting the topic of the Conference anew will rekindle the interest of the original participants while it may attract others and give them an impression of what the Grotius Seminarium is trying to do. In addition, those of the papers which dealt with the more general aspects of the Confer­ ence's topic are presented in this booklet. B. LANDHEER December, 1959 TABLE OF CONTENTS· 1. Preface. 3 II.
