Reading edition
κριτήριον δὲ τῆς ἀληθείας φασὶ τὴν καταληπτικὴν φαντασίαν, τουτέστι τὴν ἀπὸ ὑπάρχοντος, καθά φησι Χρύσιππος καὶ Ἀντίπατρος καὶ Ἀπολλόδωρος Diog. L. vii 54. This view is attributed to Zeno himself: ‘visum [Zeno ita definiit] ex eo, quod esset, sicut esset, impressum et signatum et effictum’ Cic. Ac. ii 24, 77.
