Agnes Heller continued her commitment to socialist theory, seeking a democratic alternative to the actually existing socialist system in Soviet-type societies in the early 1980s. Heller conceptualized socialism as a long-term social experiment based on social imagination and the radicalization of democracy, which contrasted with the Soviet socialist project on the one hand, and went beyond Western parliamentary systems on the other hand. My aim in this paper is to examine the 1982 pamphlet, Why We Should Maintain the Socialist Objective, (...) and present it as a crucial step that Heller takes to depart from Marxism and explore her post-Marxist socialist theory. This paper will examine the social imagination, radicalization of democracy, and other key ideas elaborated in the pamphlet, linking these ideas to her subsequent book, Dictatorship Over Needs, and her essay ‘The Great Republic’.
