The Notre Dame Symposium of April, 1966, was not only one of the very first to bring ""socialist"" and ""capitalist"" scholars together to discuss basic questions, it was also ""the first truly international meeting concerned with the ideas of Karl Marx."" While papers were presented on the relevance of Marxism to the contemporary Far East, the Moslem World, and Latin America, the title is precise because one dominant purpose of the conference was to consider Marx's ideas in their original form. In this light, freed of the bewildering shadows cast by subsequent events, Karl Marx has obvious sources and a solid position within the Western tradition of political philosophy. Other topics dwelt upon are the relationship of Marxism to Christianity, to religion in general, and to American democracy; his theory of ethics; his concept of alienation, and whether or not his work is or was of any use to the proletariat. It is, as the editor points out, ""no exaggeration"" to say that this volume contains the distilled efforts of some of the most prominent Marx specialists anywhere in the world today. Another stated purpose--""to contribute the intellectual's small share to peace and a better world by exchanging views""--may or may not have been served, but certainly this is a rewarding, if difficult volume for the serious reader, whatever his persuasion.
