In U.S.S.R. dialectical materialism is still the only subject discussed by writers on philosophy. Philosophical publications during the last year include Lenin’s Philosophical Note-books; Dialectical Materialism and the Theory of Balance, by Selektor; Marx’s Philosophical Development, by Lipendin; A Course of Dialectical Materialism, by Markuse; Dialectical Materialism and Social Democracy, by Rudash; The Idealistic Dialectic of Hegel and the Materialist Dialectic of Marx, by L. Axelrod. On the occasion of the fiftieth anniversary of Marx’s death the Communist Academy Institute of Philosophy has published a Symposium containing papers on materialistic dialectics, on the relation of Marxism-Leninism to culture and natural science, and discussion of those papers. A number of small textbooks on dialectical materialism, or Diamat as it is called for short, are issued for university schools not only in Russian but also in some of the languages spoken in the Soviet Union.
