Abstract

This paper challenges the hitherto common distinction between Hermann Cohen’s early phase of Völkerpsychologie and his later phase as a critical idealist. Recently, it has been claimed that Cohen’s turn was not a rapid conversion but a development that was already inherent to his early view. This paper argues that even in Cohen’s mature critical idealism, a thin basis of Völkerpsychologie continues to exist. Cohen’s critical programme is presented as having a twofold aim: On the one hand, it strives to give an account of pure, formal, and logical laws that regulate critical thinking; on the other hand, it offers a reading of Kant’s dualism between matter and form that allows critical thinking to be seen as inevitably embedded in causal laws of psychology, history, and physiology. Concerning the latter, the paper argues that Cohen remained in the tradition of Völkerpsychologie in his mature ethical thought.
