This paper argues that the normative dimension in mental and semantic content is not a categorical feature of content, but an hypothetical one, relative to the features of the interpretation of thoughts and meaning. The views of Robert Brandom are discussed. The thesis defended in this paper is not interpretationist about thought. It implies that the normative dimension of content arises from the real capacity of thinkers and speakers to self ascribe thoughts to themselves and to reach self knowledge of their own thoughts.
