Antilogies in Ancient Athens: An Inventory and Appraisal

Antilogies, or pairs of symmetrically opposed speeches or arguments, were generally ignored by Plato, Isocrates, Aristotle, Cicero, and Diogenes Laertius, and, later, by Eduard Norden, Hermann Diels, and most modern scholars of antiquity. As a consequence, until the end of the twentieth century CE, antilogies have been ignored or, at best, treated as a minor literary device to be mentioned only with reference to individual writings. Nevertheless, during the second half of the fifth century, antilogies were a crucially important form of argument and persuasion in ‘sophistic’ thought, philosophy, historiography, comedy and tragedy, and other fields. In order to redress the historical neglect of the art of antilogy, this essay provides an inventory (doubtless incomplete) of some 30 antilogies composed by playwrights such as Sophocles, Euripides, and Aristophanes, historians such as Herodotus and Thucydides, and, most importantly, ‘sophists’ such as Protagoras, Gorgias, Prodicus and Antiphon (in addition to a few other writers of the same period). Building on this inventory, the second part of the essay seeks to establish identifying features of antilogy and assess its cultural significance in the Athenian context (in the second half of the fifth century BCE).
