'Demagogues and Democracy'

'The term 'demagogue' (dēmagōgos) arose in Greece during the fifth century B.C.E. to describe a new breed of charismatic politicians who sought to lead the masses by arousing their passions and appealing to their prejudices. In contrast to political figures who advocated courses of action that they believed were in the common good, demagogues used their rhetorical skills to promote policies that advanced their self-interests."

"Cleon was heralded by his supporters for speaking frankly..."telling it like it is"...Aristotle demurred that on the contrary bluster and bravado typified his oratory: 'He was the first who shouted on the public platform, who used abusive language and who spoke with his cloak girt around him, while all the others used to speak in proper dress and manner.' The historian Thucydides added that Cleon was the most violent man in Athens, someone prepared to brand those who disagreed with him as 'enemies of the people.' "
