The text introduces a translation of Ilyenkov’s famous text “On the State of Philosophy,” which was meant as a letter to the Central Committee of the CPSU and expressed his exasperation with the development of Soviet philosophy. In our introduction, we describe the historical context of the emergence of the letter, including the main changes in Soviet philosophy in the 1960s (esp. rise in popularity of cybernetics), and the institutional details of Ilyenkov’s biography. We point to the contemporary relevance of (...) the letter by emphasizing how Ilyenkov’s dialectical account of science can enrich contemporary discussions in the sociology of science and STS.
