[1342] Vita, cap. 15. It will be noted that like some of the church fathers Plotinus attacked genethlialogy rather than astrology. Προσεῖχε δὲ τοῖς μὲν περὶ τῶν ἀστέρων κανόσιν οὐ πάνυ τι μαθηματικῶς, τοῖς δὲ τῶν γενεθλιαλόγων ἀποτελεστικοῖς ἀκριβέστερον. καὶ φωράσας τῆς ἐπαγγελίας τὸ ἀνεχέγγυον ἐλέγχειν πολλαχοῦ καὶ (τῶν) ἐν τοῖς συγγράμμασιν οὐκ ὤκνησε.
[1343] Ennead II, 3, Περὶ τοῦ εἰ ποιεῖ τὰ ἄστρα. Porphyry arranged his master’s treatises in the form of six enneads of nine each and perhaps somewhat revised them at the same time.

[1346] Ennead II, 3 (p. 242), Ὅτι ἡ τῶν ἄστρων φορὰ σημαίνει περὶ ἕκαστον τὰ ἐσόμενα ἀλλ’ οὐκ αὐτὴ πάντα ποιεῖ, ὡς τοῖς πολλοῖς δοξάζεται, εἴρηται μὲν πρότερον ἐν ἅλλοις. See also Ennead III, 1, and IV, 3-4.

[1349] Polycraticus, II, 19, (ed. C. C. I. Webb, 1909, I, 112). Mr. Webb (I, xxviii) holds that John of Salisbury “certainly did not have Plotinus,” and derived some passages from his works through Macrobius and Augustine; but he is unable to state in what intermediate source John could have found the passage now in question. It does not seem to reflect Plotinus’ doctrine very accurately.

[1351] Ibid., 30. Guthrie’s translation, “We have shown that memory is useless to the stars: we have agreed that they have senses, namely, sight and hearing,” is quite misleading, as caps. 40-42 make evident.
