Participatory Athenian democracy has inspired many political thinkers, despite its imperialist atrocities, slavery and the subordination of women. Pericles is an ambivalent figure, and it is dangerous to see him as the embodiment of a golden age. His speech over the war-dead can be seen as a noble democratic manifesto or the calculated work of a demagogue. In a debate about the punishment of Mytilene, as depicted by Thucydides, Cleon uses the language of reason to work on the emotions, and is a paradigm of the populist or ‘demagogue’. We can see the ‘demagogue’ as an aberration from true democracy, or see the word itself as a standard weapon that can be wielded in any democratic contest. The comic dramatist Aristophanes offers us insight into Cleon’s performance techniques that embrace face, arms and voice, and into the minds of those who supported him. In his Gorgias, Plato theorises the problem of rhetoric. Gorgias was a Sicilian who taught the Athenians that rhetoric was an art which they could pay to learn, and for Plato this was a fundamental flaw in his nation’s democratic enterprise.
