[33] ‘adsensio nostra erit in potestate’ Cic. Fat. 19, 43; ‘adsensio non [potest] fieri nisi commota viso; tamen id visum proximam causam [habet], non principalem’ ib. 18, 42; ‘[Zeno] adsensionem adiungit animorum, quam esse vult in nobis positam et voluntariam’ Cic. Ac. i 11, 40.

[35] ‘opinationem autem volunt esse imbecillam adsensionem’ Cic. Tusc. disp. iv 7, 15; ‘opinio quae [est] imbecilla et cum falso incognitoque communis’ Cic. Ac. i 11, 41; so Sext. math. vii 151 (Arnim ii 90).

[39] Cicero’s point of view appears to be that the mind-picture grasps the object: ‘[visum] cum acceptum iam et adprobatum esset, [Zeno] comprehensionem appellabat, similem eis rebus quae manu prehenderentur’ Cic. Ac. i 11, 41. See further Stein, Psych. ii 174, and R. D. Hicks, Stoic and Epicurean, p. 71.
[40] This view is expressed by Posidonius, who bases it on Plato’s Timaeus: ὡς τὸ μὲν φῶς ὑπὸ τῆς φωτοειδοῦς ὄψεως καταλαμβάνεται, ἡ δὲ φωνὴ ὑπὸ τῆς ἀεροειδοῦς ἀκοῆς, οὕτως ἡ τῶν ὅλων φύσις ὑπὸ συγγενοῦς ὀφείλει καταλαμβάνεσθαι τοῦ λόγου Sext. Emp. math. vii 93. See also below, § [266].
[41] ‘comprehensio facta sensibus et vera esse [Zenoni] et fidelis videbatur; non quod omnia, quae essent in re, comprehenderet, sed quia nihil quod cadere in eam posset relinqueret’ Cic. Ac. i 11, 42.
[42] Diog. L. vii 51; ‘quam multa vident pictores in umbris et in eminentia, quae nos non videmus!’ Cic. Ac. ii 7, 20.
