Sophocles (c. 496-406/405 BCE)
“Of course you cannot know a man completely,
his character, his principles, sense of judgment,
not till he’s shown his colors, ruling the people,
making laws. Experience, there’s the test.”
- From Sophocles’ Antigone, approximately between lines 170-180, translated by Robert Fagles (Penguin Classics, 1982, 1984, 2018).
