"If Socrates, with his dream of a discoverable philosophy of absolute truth, is the modernist voice, then Protagoras is the proponent of a multivocal universe. Whatever the issue, there is always something else to be said, another voice to be heard. In this respect, Protagoras very much cuts a postmodern dash."
