Soviet citizens perusing their daily copies of Pravda or Izvestiia on May 23, 1934, would have come across an essay by the famous writer Maksim Gor΄kii with an unusual title: “Proletarskii gumanizm” (Proletarian Humanism). Perhaps intrigued by this funny sounding but clearly important foreign word, inquisitive readers might have turned to the recently published first edition of the Great Soviet Encyclopedia (BSE), which provides two entries for humanism: one referring to “a conventional but not sufficiently precise term used to characterize the culture of the Renaissance epoch, or some aspect thereof,” and a second, much shorter entry concerning “a modern movement in the theory of knowledge that arose in the early twentieth century in connection to pragmatism.” Neither entry makes any mention of proletarian, socialist, or Soviet varieties of humanism. Indeed, according to the BSE, Renaissance humanism inevitably “exhausts its progressive possibilities, degenerates, and becomes a conservative and reactionary force,” remaining “alien to the broad masses and even a significant part of the bourgeoisie.”
