Dilthey was interested in psychology. In his work "Ideas Concerning a Descriptive and Analytic Psychology" ("Ideen über eine beschreibende und zergliedernde Psychologie", 1894), he introduced a distinction between explanatory psychology ("erklärende Psychologie"; also explanative psychology) and descriptive psychology ("beschreibende Psychologie"; also analytic psychology, "zergliedernde Psychologie"): in his terminology, explanatory psychology is the study of psychological phenomena from a third-person point of view, which involves their subordination to a system of causality, while descriptive psychology is a discipline that attempts to explicate how different mental processes converge in the "structural nexus of consciousness."
