Ancient Greek playwright Aeschylus who redefined theater and was known as the 'Father of Tragedy' gave us this lofty quote, which serves as a survival lesson even today. In his play Prometheus Bound, Oceanus gives this advice to Prometheus, suggesting that when dealing with powerful tyranny like Zeus, it is sometimes safe and smarter to pretend that you don't know anything or to lay low rather than flaunt your intellect.
