As far as existence of enduring subjects of change is concerned, Roman Ingarden's substance ontology stands in direct opposition to Whitehead's process metaphysics. However, with regard to domain of necessary relations, both systems are deeply platonic. Thus in this paper I pursue towards revealing some parallels and differences between both systems regarding views on ideal entities, necessary relations and pure possibilities. I examine whether having assumed contrary concepts of reality (substantial/procesual) both philosophers are forced to accept diverse conclusions in respect (...) to ideal entities domain. I also point out some crucial problems that are to be found in both systems: what is the ground of necessary relations – is it a nature of so called ideal qualities, or is it content of ideas (Ingarden); is it an individual or a relational essence of eternal objects, so called "primordial nature of God", or evolving actuality (Whitehead). Finally I investigate whether points of convergence between both concepts could serve as a basis for some modifications to overcome relevant problems. (shrink)

In this text I take into account Roman Ingarden's theory of general objects. Polish phenomenologist avoided most of paradoxes implied by traditional theories of universals pointing out the difference between two kinds of form inherent in general object, namely form of subject of properties and form of whole and parts. Every idea has twofold construction: as an idea (qua idea) it is a subject of peculiar properties and on the other hand it has a content consisted of so called constants (...) and variables. The content of the idea has a whole-parts form. This however is inconsistent with other analyses of whole-parts form and of the character of constants and variables given by Roman Ingarden. In the consequence I claim that a third form, unique for general object, is needed. I also point out difficulty of indicating positive characteristic of general object (i.e. other than negation of properties of individuals). (shrink)
