Ontology is doubtless the most important part of Roman Ingarden’s (1893-1970) philosophy. Contrary to Husserl, Ingarden always believed that any serious philosophical investigation must involve an ontological basis and he tried to formulate a solid ontological framework for his philosophy. There are several reasons why this ontology deserves our attention. For those who are interested in Husserl’s transcendental phenomenology, Ingarden’s ontology could be treated as an ingenious attempt to analyse the conceptual structure and hidden ontological assumptions of Husserl’s transcendental idealism. (...) For those who want to understand the immanent dialectics of the post-Brentanian development of the ontology of intentionality, Ingarden’s conception of the purely intentional object could be a very valuable tool. But Ingarden’s ontology has also independent value, and hence it is also interesting for those who pursue ontology for its own sake. In this paper, I will investigate the basic scheme of Ingarden’s ontology, including pure qualities, individual real objects, purely intentional objects and ideas. This schema will prove to be in many aspects generated by his phenomenological, i.e. descriptive and anti-reductionist, ideology. (shrink)

In classical topology the only part of a doughnut that matters is the edible part. Here I review some good reasons for reversing the order and focusing on the hole instead. By studying the topology of the hole one can learn interesting things about the morphology of the doughnut (its shape), and by studying the morphology of the hole in turn one can learn a lot about the doughnut’s dynamic properties (its patterns of interaction with the environment). The price--of course--is (...) that one must be serious about reifying voids. (shrink)
