This paper briefly describes Sellars' view on common sense - concepts ("manifest image") and linguistic meaning and introduces his account of linguistic-cognitive framework ("logical space of reasons"), that is the base of human conceptualization of the world. The paper focuses on the critique of Sellars' views by Hilary Putnam and John McDowell, who contest the lack of reference in the objects and properties of common-sense concepts and challenge his internalist and inferentialist view of semantics.
