  Roman Ingarden (1893–1970) was a Polish phenomenologist, ontologist and aesthetician. A student of Edmund Husserl’s from the Göttingen period, Ingarden was a realist phenomenologist who spent much of his career working against what he took to be Husserl’s turn to transcendental idealism. As preparatory work for narrowing down possible solutions to the realism/idealism problem, Ingarden developed ontological studies unmatched in scope and detail, distinguishing different kinds of dependence and different modes of being. He is best known, however, for his work in aesthetics, particularly on the ontology of the work of art and the status of aesthetic values, and is credited with being the founder of phenomenological aesthetics. His work The Literary Work of Art has been widely influential in literary theory as well as philosophical aesthetics, and has been crucial to the development of New Criticism and Reader Response Theory.
