ABSTRACT
This chapter considers problems that concern both semiotics as constitutive phenomenology and philosophy of language. The focus is on logic and theory of knowledge considered in the perspective of their formation. It argues that a very close relationship is established between semiotics, philosophy of language, gnoseology (theory of knowledge), logic, ontology and metaphysics. One of the authors who most explicitly relates all these aspects is Charles S. Peirce. More recently, through close discussion of Martin Heidegger's philosophy, Emmanuel Levinas has also very importantly contributed to this area of research with his claim that metaphysics cannot be eliminated from ontology. The chapter further deals with the formation of predicative judgement starting from primary iconism, or protosemiosis. For that, it discusses Edmund Husserl's analyses considered in the light of Peirce's semiotics. Peirce's semiotics is not at all distant from Husserl's phenomenology, while the latter is semiotically oriented though independently from Peirce.
