Frederic Jameson sees Lyotard as responding to a contemporary "crisis of representation" in the sciences — a crisis which calls into question "an essentially realistic epistemology, which conceives of representation as the reproduction, for subjectivity, of an objectivity that lies outside it — projects a mirror theory of knowledge and art, whose fundamental evaluative categories are those of adequacy, accuracy, and Truth itself."
