The purpose of this paper is to show how the thought and speech of people holding and defending directly opposite positions affect the change in the thought and speech of people of their own and subsequent generations, with different life orientations, and to find ways of this influence. The author describes the situation that arose at the end of the sixties of the twentieth century, known as the ideological dispersal of philosophical, historical and sociological trends that ran counter to the policy of the CPSU, which became especially fierce in the fight against opponents after the USSR’s invasion of Czechoslovakia in August, 1968. One of the results of such an ideological battle was the defeat of the sector of the methodology of history of the Institute of General History of the USSR Academy of Sciences, headed by M. Ya. Gefter, who published a series of books in which the so-called laws of historical development (formational approach) were questioned and the fundamental provisions of the classics of Marxism-Leninism were criticized. The subject of analysis is Gefter’s article “A Page from the History of Marxism in the Early 20th Century”, published in the book “Historical Science and Some Problems of the Modernity”, dedicated to the analysis of Lenin’s tactics and strategy development which changed the views of many, especially young, historians on the historical process, and most importantly - on the methods of seeking and expressing the truth. The differences were expressed primarily in the fact that the proponents and defenders of the Soviet regime, which was based on their own established norms of Marxism-Leninism, fearlessly used all means of pressure on unwanted opponents. Professionals, however, who tried to understand the true sense of the historical process, the sense of judgments about it, especially the sense of the revolutionary struggle against the autocracy, unfolding at the beginning of the twentieth century, were forced to use the Aesopian language, which also provoked a distortion of this sense in many ways: due to the nebulous and veiled expressions, which give the impression of theoretical blackmail, causing such consequences as speech irresponsibility.
