In 2020, we celebrate the 50th anniversary of the death of Roman Ingarden (1893- 1970). Ingarden was one of the greatest philosophers of the 20th century. He significantly contributed to ontology and aesthetics and was a leading representative of phenomenology. Ingarden was strongly associated with the Lvov-Warsaw School (LWS), founded by Kazimierz Twardowski in Lvov in 1895. Although Ingarden is not considered a member of the School, there are some interesting connections between him and members of the LWS. Firstly, before Ingarden began his studies under supervision of Edmund Husserl in Göttingen, he had studied for a year in Lvov under Twardowski. Secondly, in 1933 he got the Chair of Philosophy in Lvov, where simultaneously Twardowski’s students were active. Thirdly, after the Second World War, Ingarden became close to some of Twardowski’s students and colleagues; at the Jagiellonian University he cooperated with Izydora Dąmbska, one of Twardowski’s former student and assistant. Ingarden also shared a scientific ethos with the LWS, which was probably motivated by common tradition and intellectual origin: both Twardowski and Husserl were students of Franz Brentano. The aim of the symposium is to explore the relationship between Ingarden and the LWS, and, in a broader perspective, the relationship between the early analytical philosophy and Ingarden’s phenomenology.
