The nrst of the people to be thanked for their help during the composition of this work is Professor I.M. Bochenski, under whom I had the good fortune to study for an extended period of time. Without his help, it is doubtful that this work would have been writt"l1 at all. Among the other professors who helped along the way, I would like to cite in particular Professors A.F. Utz, M.D. Philippe and N. Luyten of the University of Fribourg. Many friends were present at the birth of the ideas contained in this book. By naming K.G. Ballestrem, T.l. Blakeley and M.F. Gagern, I do not want to slight any of the rest. It was A. Spiekermann in Hollinghofen who saw to it that other preoccupations did not rob me of all the time needed for the study of the subject-matter and to the composition of this treatise. Of particular help in getting sources from the libraries of the world were Miss Lifschitz of the Institute of East-European Studies and Mr. Uldry of the Cantonal Library in Fribourg, Switzerland. Finally, my patient typist, Mrs. Frey in Munster, deserves special mention for her beautiful work.

A survey of the intellectual history of Marxism through its several phases and various national adaptations suggests, for any of at least three reasons, that the attempt to provide a widely acceptable summary of 'Marxist ethics' must be an enterprise with little prospect of success. First, a number of prominent Marxists have insisted that Marxism can have no ethics because its status as a science precludes bias toward, or the assumption of, any particular ethical standpoint. On this view it would be no more reasonable to expect an ethics of Marxism than of any other form of social science. Second, basing themselves on the opposite assumption, an equally prominent assortment of Marxist intellectuals have lamented the absence of a coherently developed Maryist ethics as a deficiency which must be remedied. ! Third, less com monly, Marxism is sometimes alleged to possess no developed ethical theory because it is exclusively committed to advocacy of class egoism on behalf 2 of the proletariat, and is thus rooted in a prudential, not a moral standpoint. The advocacy of proletarian class egoism - or 'revolutionary morality- may, strictly speaking, constitute an ethical standpoint, but it might be regarded as a peculiar waste of time for a convinced and consistent class egoist to develop precise formulations of his ethical views for the sake of convincing an abstract audience of classless and impartial rational observers which does not happen to exist at present.

`Scientific history of philosophy' was one of the professional branches of Soviet philosophy, and a place where philosophical culture was preserved in an often hostile environment. Situated between the ideological exigencies of the Soviet system with its Marxist-Leninist `theoretical foundation' and the need for an objective account of philosophy's past, Soviet history of philosophy displays the characteristic features of Soviet philosophy as a whole, including a forceful reappearance of its Hegelian background. This book is the only Western monograph on this important part of Soviet philosophy, thus filling the last main gap in Western `Philosophical Sovietology'. At the same time, it offers the first survey of Soviet philosophy after the disappearance of the Soviet system itself, embarking on an historical and meta-philosophical investigation of Soviet philosophical culture. The book will be of interest to students of Soviet and Russian philosophy, historians of philosophy and specialists in Soviet studies.
