There is a passage in Plato’s dialogue Gorgias which I love. Two and a half thousand years ago, and these fellows are still with us. It speaks to the present moment; we might think we live in a different world to that of Ancient Greece, but it is just a blink away.
Plato describes Socrates visiting at the house of a friend, quizzing one of Greece’s most renowned speakers, Gorgias. Gorgias was immensely wealthy; a skilled user of rhetoric who could persuade others to his views, and those who wished to become likewise powerful and influential paid him vast amounts to be taught the tricks.
