Metaphysical and phenomenological foundations and outcomes of regional ontology

The paper deals with the analysis of metaphisical and phenomenological classification of the forms of existence and being. The author demonstrates that the key forms of being in the phenomenological classification - the regional ontology of material nature and of the world of man - turn out to be, in the course of their constitutive analysis, not distinct regions but the ones that are conditioned upon each other. The same type of interconnectedness is revealed in the forms of existent within the metaphisical classification: nature, culture, man, and society. Only a synthesis of these forms can be defined as the “substance”. All other syntheses, along with pure regions of the existece, can be organized in two groups: constructs whose delineation is determined by a real motive or by the existent’s own organisation/structure, and regions that are redundant.
