About this work
Lives and Opinions of Eminent Philosophers is Diogenes Laertius's compendium of the lives, teachings, and sayings of the Greek philosophers, written in the third century CE. Gossipy, anecdotal, and endlessly quotable, it is our single richest source for the personalities behind ancient thought, often the only place a philosopher's words survive at all.
About the author — Diogenes
Diogenes Laertius was a third-century biographer about whom almost nothing is known, except that his survey of Greek philosophy preserved a tradition that would otherwise have been lost. For many ancient thinkers, his book is why we still have their words.
