Editing Diogenes Laertius (section)

===Organization of the work===
Diogenes divides his subjects into two "schools" which he describes as the [[Ionian School (philosophy)|Ionian/Ionic]] and the Italian/Italic; the division is somewhat dubious and appears to be drawn from the lost [[doxography]] of [[Sotion]]. The biographies of the "Ionian school" begin with [[Anaximander]] and end with [[Clitomachus (philosopher)|Clitomachus]], [[Theophrastus]] and [[Chrysippus]]; the "Italian" begins with [[Pythagoras]] and ends with [[Epicurus]].  The [[Socrates#Legacy|Socratic school]], with its various branches, is classed with the Ionic; while the [[Eleatics]] and [[Pyrrhonism|Pyrrhonists]] are treated under the Italian. He also includes his own poetic verse about the philosophers he discusses.

The following list shows the organization of philosophers discussed in the work:{{sfn|White|2020|pp=482-484}}
