Abstract

The aim of this paper is to reconstruct the research program of formal ontology developed by M. Scheler before his last 1922 theoretical shift. Scheler’s theory of dialectical negation will be also investigated. In regard to the first topic, the focus will be on the complex architecture of Scheler’s formal ontology, deepened within a theoretical framework of realistic ontology: integrated into this framework, formal ontology becomes a basic tool for building phenomenological realisms. In regard to the second topic, the focus will be on the close theoretical relationship between Scheler’s mature suggestion of a phenomenological objective dialectics essence-being underlying his theory of the “functionalization of the essential knowledge” (Funktionalizierung der Wesenserkenntnis) ─ systematically presented for the first time in the 1921 work Probleme der Religion ─, and the formal ontological foundation of a logical theory of a “pluralistic” dialectical negation, that is, dually, an intuitionistic, hence paracomplete, and a paraconsistent negation. Finally, it will be introduced the basics of a semiotic interpretation of Scheler’s phenomenological formal ontology within the rigorous framework of Category Theory (TC). This interpretation “strengthens” the traditional (inter)subjective side of phenomenological analysis with a new ─ in the application suggested ─ “in the third person” objective side of semiotic analysis, that shares with the first one a common pre-logical and ante-predicative level of inquiry.
