The conj. of Kayser veri nota for vetera (cf. 76) and investigatum below, is fanciful and improbable. Quod investigata sunt:  “in that an investigation was made.”  Herm. again disturbs the text which since Madv. Em. 127 supported it (quoting T.D. V. 15, Liv.  XXXV. 16) had been settled.  Holding that illa in the former sentence cannot be the subj. of the verb, he rashly ejects nihilne est igitur actum as a dittographia (!) from 15 nihilne explicatum, and reads quot for quod with Bentl.  For the meaning cf. T.D. III. 69 and Arist. on the progress of philosophy as there quoted. Arcesilas Zenoni ... obtrectans:  see n. on I. 34.  These charges were brought by each school against the other.  In Plutarch Adv.  Colotem p. 1121 F, want of novelty is charged against Arcesilas, and the charge is at once joyfully accepted by Plut.  The scepticism of Arcesilas was often excused by the provocation Zeno gave, see Aug. Contra Acad. II. 14, 15 and notes on fragm. 2 and 35 of the Academica Posteriora. Immutatione verborum:  n. on I. 33.  This phrase has also technical meanings; it translates the Greek [Greek:  tropoi] (Brut. 69) and [Greek:  allegoria] in De Or. II. 261, where an ex. is given. Definitiones:  n. on 18. Tenebras obducere:  such expressions abound in Cic. where the New Academy is mentioned, cf. 30 (lucem eripere), N.D. I. 6 (noctem obfundere) Aug. Contra Ac. III. 14 (quasdam nebulas obfundere), also the joke of Aug.  II. 29 tenebrae quae patronae Academicorum solent esse. Non admodum probata:  cf. the passage of Polybius qu. by Zeller 533. Lacyde:  the most important passages in ancient authorities concerning him are quoted by Zeller 506.  It is important to note that Arcesilas left no writings so that Lacydes became the source of information about his teacher’s doctrines. Tenuit:  cf. the use of obtinere in De Or. I. 45. In Aeschine:  so Dav. for the confused MSS. reading.  For this philosopher see Zeller 533.  As two MSS. have hac nonne Christ conj. Hagnone which Halm, as well as Baiter takes; Zeller 533 seems to adopt this and at once confuses the supposed philosopher with one Agnon just mentioned in Quint.  II. 17, 15.  There is not the slightest reason for this, Agnon and Hagnon being known, if known at all, from these two passages only.

Sec.17. Patrocinium:  for the word cf. N.D. I. 6. Non defuit:  such patronage was wanting in the time of Arcesilas (16). Faciendum omnino non putabant:  “Epictetus (Arrian, Diss. I. 27, 15) quietly suppresses a sceptic by saying [Greek:  ouk ago scholen pros tauta]” (Zeller 85, n.).  In another passage (Arrian, I. 5) Epict. says it is no more use arguing with a sceptic than with a corpse.
