Max Horkheimer discusses the relationship between history and psychology, emphasizing the need for a characterization of the role of psychology in the context of a theory of history. He identifies two logically opposed concepts of history, one based on Kantianism and the other on contemporary efforts to make ideological questions independent of scientific criteria. Horkheimer argues that existential philosophy in the phenomenological tradition seeks to make itself independent of the results of research in various spheres, and that the economic or materialist conception of history reveals itself as both the antithesis and the continuation of Hegelian philosophy. He also highlights the significance of psychology for historical knowledge, emphasizing the need for a psychology that accommodates the needs of the human sciences and overcomes the weakness of academic psychology. Horkheimer concludes by discussing the general significance of detailed psychological work for historical research and the importance of psychology in the current period.
