Abstract

At the end of the 19th century, two monographs on empirical psychology were published: W. Wundt’s Grundzüge der physiologischen Psychologie and F. Brentano’s Psychologie vom empirischen Standpunkt. They set different research standards, indicating a differently defined subject as well as the methodology of the new science. The psychology of the 20th and 21st centuries focused mainly on Wundt’s program, while Brentano’s program was included in philosophical analyses. However, this led to significant changes in psychology, which today can be seen as deep reductionism, narrowing the subject matter, and difficulties in constructing theories. In the article, I suggest that it might be helpful to recall the basic assumptions of Brentano’s psychology and the schools derived from it, such as e.g. the Lvov‑Warsaw School. Therefore, the article aims to indicate the theoretical space that has been emerging for some time, in which the school of Kazimierz Twardowski could present original philosophical and psychological achievements.
