This essay is an introduction to a lecture course "Elements of Descriptive Psychology" delivered by Anton Marty in around 1903/04. Marty offered courses on descriptive psychology at regular intervals in the course of his career at the University of Prague. The content of these courses follows closely the ideas of Marty’s teacher Franz Brentano, though with some interesting divergences and extrapolations. The present work is a historical and systematic introduction to an extract from notes taken of Marty’s lecture, with some (...) discussion of the work of Dilthey on similar topics, and of Marty’s influence on Franz Kafka and on the Gestalt psychologist Max Wertheimer.
