[336] Stobaeus Eclogae I p. 138, 23 W. Χρυσίππου. Χρύσιππος αἴτιον εἶναι λέγει δι’ ὅ. Καὶ τὸ μὲν αἴτιον ὂν καὶ σῶμα ⟨οὗ δὲ αἴτιον μήτε ὄν, μήτε σῶμα⟩ καὶ αἴτιον μὲν ὅτι, οὗ δὲ αἴτιον διά τι. Αἰτίαν δ’ εἶναι λόγον αἰτίου, ἢ λόγον τὸν περὶ τοῦ αἰτίου ὡς αἰτίου. Sequitur simillima Posidonii disputatio (Diels Arii Didymi Epit. phys. frgm. 18). Cf. Zeno I n. 89
