Ingarden began his university studies in Lvov, under Twardowski, the founder of the Lvov-Warsaw School (LWS, for brevity). However, he moved on to Göttingen after one semester. In Germany he studied with Husserl between 1912 and 1918, and obtained his PhD in Freiburg. He then returned to Poland in 1919, obtained his habilitation in Lvov in 1924, and became a full professor in 1933 at Lvov’s Jan Kazimierz University. Ingarden always remained a faithful phenomenologist, although he did not accept the transcendental phenomenology of late Husserl. One can say that Ingarden worked in an environment dominated by LWS in the years 1924–1939. Clearly, Ingarden’s philosophy was radically opposed to that represented by Twardowski and his students: there was really no possibility of compromise between the two styles of doing philosophy. Both sides of the debate, Ingarden as well as members of LWS, often underlined this fact. Yet there are many passages in Ingarden which can be understood as either direct or indirect critiques of LWS, particularly on the subject of logic and its role in philosophy. Similarly, some fragments of the writings of LWS might be interpreted as critical allusions to Ingarden, for instance, concerning a priori or intuition as devices for the cognition of essences. We could speculate that Ingarden’s realism was partially inspired by the realistic attitude of LWS. However, the personal relations between Ingarden and LWS were rather cold, at least before 1939. He accused some members of LWS of blocking his academic carrier. The situation changed after 1945 – their relations improved as they all fought against the dominance of Marxism, and also thanks to the natural solidarity between Lvovians.
