Abstract
In this paper, we will consider Brandoms fundamental components of his undestanding of interesting concept of expresive rationality. I think it’s necessary, in orded to gain logical distinction of this concept, to analise and postulate basic meanings and parts of Brandoms philosophy. In this paper, we will interpret and explain the fundamental tenets of Robert Brandom’s intriguing concept of expressive rationality. Brandom, in his research on linguistic practices and their implications, approaches the topic from the perspective of inferentialism, a specific approach to the theory of meaning. Inferentialism is based on determining the meaning of expressions through their correspondence with other expressions.
