 Habermas's critique of postmodernism on the basis of performative contradiction and the paradox of self-reference sets the tone and the terms for much of the critical debate now under way. While postmodernists have rejected these criticisms, or responded to them with rhetorical counter-strategies.  Lyotard, for example, rejects the notion that intersubjective communication implies a set of rules already agreed upon, and that universal consensus is the ultimate goal of discourse (see Lyotard 1984 [1979], 65-66).  That postmodernists openly respond to Habermas is due to the fact that he takes postmodernism seriously and does not, like other critics, reject it as mere nonsense. Indeed, that he is able to read postmodernist texts closely and discursively testifies to their intelligibility. He also agrees with the postmodernists that the focus of debate should be upon modernity as it is realized in social practices and institutions, rather than upon theories of cognition or formal linguistics as autonomous domains. In this respect, Habermas's concern with inter-subjective communication helps clarify the basis upon which the modernist-postmodernist debates continue to play out.
