“One must wait until the evening to see how splendid the day has been.” – Sophocles

At least according to Robert Caro, 1974. Whether or not he actually said that has been much debated like many things in his epic book.

Robert Caro didn’t pull the quote just from thin error though. It turns out that this quote was a favorite of Richard Nixon. He used it most famously in his eulogy for Senator Everett Dirksen and several other times. But again despite Nixon crediting Sophocles, there isn’t actually a lot of evidence that Sophocles actually said that.
