Ontognoseological horizon of the functions of the linguistic sign

The article considers the function of a linguistic sign that forms an intelligible integrity from the point of view of their systemic interrelations arising in the essential center of the one-to-one correspondence between being and thinking. The ontognoseological horizon determines the effectiveness and feasibility of the functions of a linguistic sign in the context of the opposition of the ideal and the real. The difference between two ways of problematization is formulated - aporetic in ontology and antinomic in epistemology. The article proposes to consider the functional ensemble of a linguistic sign. Seven main functions are identified and their system-forming oppositions are differentiated. The difference in functional dominants is shown in the course of solving the problem of universals as the main issue of medieval philosophy. A new interpretation of the “semiotic triangle” model is proposed in the light of the principles of N. Hartmann’s critical ontology according to the criteria of “stepping” and “layering”. Constitutive and regulatory factors of differentiation of linguistic functions of nomothetic minimalism are identified.
