The article explores the influences and reinterpretations of Roman Ingarden’s philosophy that can be found in Leopold Blaustein’s work. The latter studied in Lvov under Ingarden and established a long‑life philosophical dialogue with his mentor. There is a common agreement in comparative literature on the two authors which claims that Blaustein was influenced by Ingarden mainly in the field of aesthetics. This author supports a different proposition that these influences were much wider and encompassed methodology and theory of consciousness as well. The article is divided into three main parts. First, Blaustein’s critique of eidetic methods in phenomenology is reconstructed. In this context, it is claimed that Blaustein’s arguments aim at Ingarden’s concept of phenomenology rather than at Husserl’s. Yet, even if Blaustein tended to understand phenomenology as descriptive psychology, and Ingarden – as eidetic analysis, they both seemed to agree that phenomenology consisted in rigorous description of the ways of how the objects are given in experience. Secondly, Blaustein’s argument against Husserl’s theory of consciousness is reconstructed. The author claims that the argument is based on Ingarden’s differentiation between ‘living through’ and ‘experiencing’ sense data. Finally, the author examines some points that connect or divide both aesthetical theories.
