Lovers of Wisdom
Diogenes Laertius compiled the sole extant work from antiquity that gives anything like a comprehensive picture of Greek and Hellenistic philosophy. He may have been a flaming mediocrity. He may have been credulous and intellectually shallow. He may have produced a scissors-and-paste job cribbed from other ancient sources. But those other sources are lost, which makes what Diogenes Laertius left behind, to quote the Routledge Encyclopedia of Philosophy, “truly priceless.” By Jim Holt.
