Thucydides (c. 460-400 BCE)
“In investigating past history, and in forming the conclusions which I have formed, it must be admitted that one cannot rely on every detail which has come down to us by way of tradition. People are inclined to accept all stories of ancient times in an uncritical way – even when these stories concern their own native. countries.”
- From the History of the Peloponnesian War (Book I, section 20) by Thucydides, translated by Rex Warner (Penguin Classics, 1972).
