‘What is justification?’-Constructivism of Erlangen/Constanceschool as an example for problems resulting from priority of pragmatics to semantics. - R. Brandom's ‘Making it explicit’ is an attempt to work out how semantics is rooted in pragmatics: meaning in use and conceptual content in social functional roles. A philosophy that also focuses on reconstructing those norms that are implicit in pragmatics and constitutive to semanticsis developed by Constructivism of Erlangen/Constance school. This enquiry tries to work out that a discussion of constructivism might (...) be useful for a comprehension of Brandom's ‘theory of expression’, because both philosophical positions meet themselves in a pragmatic way of justification that makes it impossible to justify claims to all rational beings but only to members of those communities that share the same interests and institutions.
