Chapter 4 explores Sergei Eisenstein’s theory of the audience’s corporeal empathy, evoked by actors’ movements and graphical, nonhuman “gestures”—that is, “movements” implied by the structure of the shot composition, editing, and other formal devices. In scrutinizing Eisenstein’s theory that spectatorship is, fundamentally, an enactive experience, this chapter traces the roots of his ideas and evaluates the aesthetic and political implications of his position. First, I analyze the filmmaker’s engagement with psychological theories of William James, William Carpenter, Vladimir Bekhterev, Alexander Luria, and Lev Vygotsky, as well as the 19th-century German theorists of empathy (Einfühlung). Special attention is devoted to one of Eisenstein’s major sources: Vladimir Bekhterev’s Collective Reflexology (1921), a seminal work of early Soviet psychology, which discussed nonverbal communication in crowds and argued that the processing of visual sensations by the brain instantaneously impacts motor networks. I argue that although Eisenstein’s model of spectatorship appears manipulative, it is also potentially emancipatory. Embracing the utopian spirit of the avant-garde, he was willing to subject himself and his audience to radical experimentation aimed at testing the sensory properties of cinema and demystifying the mass production of emotions.
