Diogenes Laërtius

Biography

Diogenes Laërtius (3rd century CE) was a biographer of the Greek philosophers whose Lives and Opinions of Eminent Philosophers is the most important surviving source for the history of ancient Greek philosophy. Almost nothing is known about Diogenes himself, but his work preserves biographical details, philosophical doctrines, and anecdotes about philosophers from Thales to Epicurus that would otherwise be entirely lost. The work covers pre-Socratics, Socrates and his followers, Plato, Aristotle, the Stoics, the Epicureans, and the Skeptics. While his scholarship is uneven, Diogenes's compilation is indispensable to our understanding of ancient thought.
