[523]. Galen, x. 5, ἤριζον δ’ αὐτοῖς (the schools of Kos and Knidos) ... καὶ οἱ ἐκ τῆς Ἰταλίας ἰατροί, Φιλιστίων τε καὶ Ἐμπεδοκλῆς καὶ Παυσανίας καὶ οἱ τούτων ἑταῖροι κ.τ.λ. Philistion was the contemporary and friend of Plato; Pausanias is the disciple to whom Empedokles addressed his poem.
[524]. See Diels, “Empedokles und Gorgias” (Berl. Sitzb., 1884, pp. 343 sqq.). The oldest authority for saying that Gorgias was a disciple of Empedokles is Satyros ap. Diog. viii. 58 (R. P. 162); but he seems to have derived his information from Alkidamas, who was the disciple of Gorgias himself. In Plato’s Meno (76 c 4-8) the Empedoklean theory of effluvia and pores is ascribed to Gorgias.

[526]. See M. Wellmann, Fragmentsammlung der griechischen Ärtzte, vol. i. (Berlin, 1901). According to Wellmann, both Plato (in the Timaeus) and Diokles of Karystos depend upon Philistion. It is impossible to understand the history of philosophy from this point onwards without keeping the history of medicine constantly in view.
[527]. For the four elements, cf. Anon. Lond. xx. 25 (Menon’s Iatrika), Φιλιστίων δ’ οἴεται ἐκ δʹ ἰδεῶν συνεστάναι ἡμᾶς, τοῦτ’ ἔστιν ἐκ δʹ στοιχείων· πυρός, ἀέρος, ὕδατος, γῆς. εἶναι δὲ καὶ ἑκάστου δυνάμεις, τοῦ μὲν πυρὸς τὸ θερμόν, τοῦ δὲ ἀέρος τὸ ψυχρόν, τοῦ δὲ ὕδατος τὸ ὑγρόν, τῆς δὲ γῆς τὸ ξηρόν. For the theory of respiration, see Wellmann, pp. 82 sqq.; and for the heart as the seat of consciousness, ib. pp. 15 sqq.
[528]. Hippokr. Περὶ ἰερῆς νόσου, c 1, μάγοι τε καὶ καθάρται καὶ ἀγύρται καὶ ἀλαζόνες. The whole passage should be read. Cf. Wellmann, p. 29 n.

It would be fatal to the main thesis of the next few chapters if it could be proved that Empedokles was influenced by Leukippos. I hope to show that Leukippos was influenced by the later Pythagorean doctrine (Chap. IX. [§ 171]), which was in turn affected by Empedokles (Chap. VII. [§ 147]).
[531]. For πόροι in Alkmaion, cf. Arist. de Gen. An. Β, 6. 744 a 8; Theophr. de sens. 26; and for the way in which his embryological and other views were transmitted through Empedokles to the Ionian physicists, cf. Fredrich, Hippokratische Untersuchungen, pp. 126 sqq.
