The present reflections will be devoted to the philosophies of Jacques Derrida and Jean- François Lyotard. We will attempt here to identify differences and similarities both between these two thinkers, and among the philosophical movements which their deliberations have given rise to. In the beginning, it is obviously necessary to make some terminology standardization, because such terms as “deconstructionism,” “post-structuralism” or “postmodernism” are sometimes used in various meanings, and are often the matter at issue. As a consequence of ambiguity of all these concepts, is the fact that individual authors are included either in post-structuralism or postmodernism, even when they have dissented themselves from belonging precisely to those philosophical currents.
