I am a law student curious about the influence of Ancient Greek texts on modern U.S. political and legal thinking. One of my favorite U.S. Supreme Court opinions is from Whitney v. California, 274 U. S. 357 (1927) in which Justice Brandeis discussed the meaning of free speech in modern democracy, noting our forefathers believed: "...liberty to be the secret of happiness and courage to be the secret of liberty." Enthralled by this profound quotation, I have traced it back to Pericles' Funeral Oration from Thucydides' History, book 2, ch. 43, but want to know exactly what Pericles said in Ancient Greek because I have found many modern translations and don't know which is correct. Among the English translations I have found are:
"[esteeming] courage to be freedom and freedom to be happiness"
"[judging] happiness to be the fruit of freedom and freedom of valour"
I would be eternally grateful if anyone has access to the original Ancient Greek text and could provide the words/spelling in Ancient Greek as well as the English translation. Thank you in advance for your time.
