On Conceptual System and External Realism: Remarks on Margins of Adam Grobler's Truth and Relativity

Abstract

The notion of conceptual system is usually connected with criticism or defence of relativism but sometimes the notion appears in discussion on realism/anti-realism. The aim of the article is: (1) to present connection between understanding of notion of conceptual system and ways of understanding of realism/anti-realism; (2) to present that notion may constitute a foundation of argument for realism, although usually it is taken as argument for anti-realism. Investigations of the article create the basis for discussion of the conception of relativity proposed by Adam Grobler in Truth and Relativity.
