Diodorus Siculus (c. 1st century BCE)
“It is an excellent thing to be able to use the mistakes of others as warning examples for the correction of error, and, when we confront the vicissitudes of life, instead of having to re-investigate for ourselves, to be able to initiate the successes which have been achieved in the past.”
- From The Library of History (Book 1, Chapter 1), by Diodorus Siculus, edited by Giles Laurén (Sophron Editor, 2014).
