The first section deals with Brentano's conception of the history of philosophy. The next approaches his conception of empirical psychology from an empirical standpoint and in relation with competing views on psychology from the period. The third section discusses Brentano's later programme of a descriptive psychology or "descriptive phenomenology" and some of his most innovative developments, for instance in the theory of emotions. The final section examines metaphysical issues and applications of his mereology. His reism takes here an important place.
