The investigation of the social and epistemological context of the rejection of ontology makes György Lukács’s critique of neopositivism an important moment of his late work, Zur Ontologie des gesellschaftlichen Seins . This article argues, on the one hand, that Lukács’s critique of neopositivism can be regarded as an indispensable contribution to understand the social roots of realist attitudes towards ontology, and, on the other hand, that the target of Lukács’s marxist critique of neopositivism is indeed a special, neutral epistemological (...) position between realism and instrumentalism, which became explicit only in a later period of history of neopositivism. To prove this assumption, I investigate some components of Lukács’s critique of neopositivism-critique by showing inter alia that Lukács fails to distinguish clearly between the two different forms of realism—scientific and moderate—which lead to the rejection of ontology.
