Richard Rorty proposes a conception of knowledge to abandon objectivity pretension understood as a faithful representation of the world in our mind or in language. For him, if the world does not make our true or false beliefs, but they are justified socially (and not just for me alone, but by us), the knowledge cannot be a matter of adapting to reality, but of agreement among the members of a particular community. Thus, Rorty abandons the pretense of a universal character of epistemology and proposes a conception of knowledge that can only be justified locally, opening wings that way for his ethnocentrism, as well as his defense of the idea of knowledge as solidarity and reason as conversation. This article intends point some limits of the Rorty's neopragmatic proposal.
