<br/><br/> ‪Serguei Tchakhotin’s major work is regularly republished and cited in academic bibliographies. Even if his approach is contested, deemed too biological or exaggerating the power of persuasion of the media, the thesis he defends is nonetheless a milestone. In this book, he offers a panorama combining the possible contribution of I. Pavlov’s work on the conditioning of the brain and the manipulation of impulses, a historical presentation of the totalitarian propaganda of the 1930s, and an analysis of his personal political commitments in the service of socialism. and against Nazism. The purpose of our article is to expose the tumultuous life of this atypical researcher, crossing biological sciences and historical and political sciences, to present in detail his main demonstrations, while returning to the critical reception of the second edition, largely revised and expanded in the early 1950s.‪
