Under the auspices of UNESCO, social scientists of various disciplines and countries have held small meetings these past two years to discuss, plan and present research having to do with the general problem of peaceful co-existence. At the initial meeting, held in Geneva in 1956, it was decided to organize future sessions by academic discipline - meetings of economists, comparative jurists, of political scientists and sociologists. The sociologists' meeting was held in Moscow, January 6th to 12th, 1958. The International Sociological Association organized it; the Institute of Philosophy of the Soviet Academy of Science was host.
