Greek Texts & Translations

1.prologue.15 There is another which ends with Chrysippus, that is to say by passing from Socrates to Antisthenes, then to Diogenes the Cynic, Crates of Thebes, Zeno of Citium, Cleanthes, Chrysippus. And yet again another ends with Theophrastus; thus from Plato it passes to Aristotle, and from Aristotle to Theophrastus. In this manner the school of Ionia comes to an end.

In the Italian school the order of succession is as follows: first Pherecydes, next Pythagoras, next his son Telauges, then Xenophanes, Parmenides, ^note Zeno of Elea, Leucippus, Democritus, who had many pupils, in particular Nausiphanes [and Naucydes], who were teachers of Epicurus.

1.prologue.16 Philosophers may be divided into dogmatists and sceptics: all those who make assertions about things assuming that they can be known are dogmatists; while all who suspend their judgement on the ground that things are unknowable are sceptics. Again, some philosophers left writings behind them, while others wrote nothing at all, as was the case according to some authorities with Socrates, Stilpo, Philippus, Menedemus, Pyrrho, Theodorus, Carneades, Bryson; some add Pythagoras and Aristo of Chios, except that they wrote a few letters. Others wrote no more than one treatise each, as Melissus, Parmenides, Anaxagoras. Many works were written by Zeno, more by Xenophanes, more by Democritus, more by Aristotle, more by Epicurus, and still more by Chrysippus.

Some schools took their name from cities, as the Elians and the Megarians, the Eretrians and the Cyrenaics; others from localities, as the Academics and the Stoics; others from incidental circumstances, as the Peripatetics; others again from derisive nicknames, as the Cynics; others from their temperaments, as the Eudaemonists or Happiness School; others from a conceit they entertained, as Truthlovers, Refutationists, and Reasoners from Analogy; others again from their teachers, as Socratics, Epicureans, and the like; some take the name of Physicists from their investigation of nature, others that of Moralists because they discuss morals; while those who are occupied with verbal jugglery are styled Dialecticians.

Philosophy has three parts, physics, ethics, and dialectic or logic. Physics is the part concerned with the universe and all that it contains; ethics that concerned with life and all that has to do with us; while the processes of reasoning employed by both form the province of dialectic. Physics flourished down to the time of Archelaus; ethics, as we have said, started with Socrates; while dialectic goes as far back as Zeno of Elea. In ethics there have been ten schools: the Academic, the Cyrenaic, the Elian, the Megarian, the Cynic, the Eretrian, the Dialectic, the Peripatetic, the Stoic, and the Epicurean.

The founders of these schools were: of the Old Academy, Plato; of the Middle Academy, Arcesilaus; of the New Academy, Lacydes; of the Cyrenaic, Aristippus of Cyrene; of the Elian, Phaedo of Elis; of the Megarian, Euclides of Megara; of the Cynic, Antisthenes of Athens; of the Eretrian, Menedemus of Eretria; of the Dialectical school, Clitomachus of Carthage; of the Peripatetic, Aristotle of Stagira; of the Stoic, Zeno of Citium; while the Epicurean school took its name from Epicurus himself.

Hippobotus in his work On Philosophical Sects declares that there are nine sects or schools, and gives them in this order: (1) Megarian, (2) Eretrian, (3) Cyrenaic, (4) Epicurean, (5) Annicerean, ^note, (6) Theodorean, (7) Zenonian or Stoic, (8) Old Academic, (9) Peripatetic. 1.prologue.20 He passes over the Cynic, Elian, and Dialectical schools; for as to the Pyrrhonians, so indefinite are their conclusions that hardly any authorities allow them to be a sect; some allow their claim in certain respects, but not in others. It would seem, however, that they are a sect, for we use the term of those who in their attitude to appearance follow or seem to follow some principle; and on this ground we should be justified in calling the Sceptics a sect. But if we are to understand by "sect" a bias in favour of coherent positive doctrines, they could no longer be called a sect, ^note, for they have no positive doctrines. So much for the beginnings of philosophy, its subsequent developments, its various parts, and the number of the philosophic sects.
