Roman Ingarden (1893-1970) belonged to those phenomenologists who never accepted Husserl's transcendental idealism. He devoted a great part of his intellectual energy to the \"preparatory\" analytical studies in which he hoped to develop an ontological framework suitable for an ultimate refutation of Husserl's idealistic doctrine. In these works we find a rich arsenal of ontological tools which is interesting even for those philosophers who are not interested in the subtleties of the Husserlian tradition or esoteric dialectics of the idealism / realism debate.
