Franz Brentano is associated with the beginnings of two Polish schools of philosophy, which are associated in turn with two individuals: Kazimierz Twardowski, who initiated the Lvov-Warsaw School, and Roman Ingarden, who headed the school of phenomenology. These brief remarks come under the heading of the general axiological-aesthetic concern for values per se, such as beauty. This concept was of deep interest to several philosophers from the Lvov-Warsaw School, and thus differed from the concept of ugliness, which was of interest to only one philosopher.
