Lives and Opinions of Eminent Philosophers
Editing Lives and Opinions of Eminent Philosophers is a biography of the Greek philosophers by Diogenes Laėrtius.
It was written in Greek and professes to give an account of the lives and sayings of the Greek philosophers. Although it is at best an uncritical and unphilosophical compilation, its value, as giving us an insight into the private life of the Greek sages, justly led Montaigne to exclaim that he wished that instead of one Laėrtius there had been a dozen.
He treats his subject in two divisions which he describes as the Ionian and the Italian schools; the division is quite unscientific. The biographies of the former begin with Anaximander, and end with Clitomachus, Theophrastus and Chrysippus; the latter begins with Pythagoras, and ends with Epicurus. The Socratic school, with its various branches, is classed with the Ionic; while the Eleatics and sceptics are treated under the Italic.
The whole of the last book is devoted to Epicurus, and contains three most interesting letters addressed to Herodotus, Pythocles and Menoeceus. His chief authorities were Diodes of Magnesia's Cursory Notice of Philosophers and Favorinus's Miscellaneous History and Memoirs. From the statements of Burlaeus (Walter Burley, a 14th-century monk) in his De vita et moribus philosophorum the text of Diogenes seems to have been much fuller than that which we now possess.
