Franz Brentano and the Lvov-Warsaw School

The Polish branch of analytic philosophy, the Lvov-Warsaw School, was initiated by Kazimierz Twardowski, a student of Franz Brentano. Twardowski’s aim was to vaccinate Brentano’s spirit into Polish philosophy. He succeeded and Brentano’s impact on Polish philosophy was deep and versatile. Moreover, for few decades, Brentano’s ideas were much more popular among members of the Lvov-Warsaw School than in other centers of analytic philosophy. The paper provides an overview of Brentano’s direct and indirect impact on representatives of the Lvov-Warsaw School. Various spheres of influence, including the conception of philosophy, logic, methodology, ontology, and ethics as well as teaching philosophy are taken into considerations. This overview is preceded by some distinctions on the concept of influence.
