Gorgias

"The power of speech has the same effect on the condition of the soul as the application of drugs to the state of bodies; for just as different drugs dispel different fluids from the body, and some bring an end to disease but others end life, so also some speeches cause pain, some pleasure, some fear; some instill courage, some drug and bewitch the soul with a kind of evil persuasion."
