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,The separation of the followers of Anniceris from the Cyrenaic school was made by the author whom Clement of Alexandria followed in ii. 130. This author may have been Antiochus of Ascalon. Strabo x. 837 s.f. supports the same view: Ἀννίκερις ὁ δοκῶν ἐπανορθῶσαι τὴν Κυρηναϊκὴν αἵρεσιν, καὶ παραγαγεῖν ἀντ’ αὐτῆς τὴν Ἀννικερείαν., (6) Theodorean, (7) Zenonian or Stoic, (8) Old Academic, (9) Peripatetic.

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,Cf. the distinction drawn by Sextus Empiricus in Pyrrh. Hyp. i. 16, 17. If by rules for conduct dogmas are implied, then the Pyrrhonians are not a sect, i.e. a dogmatic school., 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.
