Angustos sensus:  Cic. is thinking of the famous lines of Empedocles [Greek:  steinopoi men gar palamai k.t.l.] R. and P. 107. Brevia curricula vitae:  cf.  Empedocles’ [Greek:  pauron de zoes abiou meros].  Is there an allusion in curricula to Lucretius’ lampada vitai tradunt, etc.? In profundo:  Dem. [Greek:  en bytho], cf.  II. 32.  The common trans. “well” is weak, “abyss” would suit better. Institutis:  [Greek:  nomo] of Democritus, see R. and P. 50.  Goerenz’s note here is an extraordinary display of ignorance. Deinceps omnia:  [Greek:  panta ephexes] there is no need to read denique for deinceps as Bentl., Halm. Circumfusa tenebris:  an allusion to the [Greek:  skotie gnosis] of Democr., see II. 73. Dixerunt:  Halm brackets this because of dixerunt above, parts of the verb dicere are however often thus repeated by Cic.

Sec.45. Ne illud quidem:  cf. 16. Latere censebat Goer. omitted censebat though in most MSS.  Orelli and Klotz followed as usual.  For the sense II. 122. Cohibereque:  Gk. [Greek:  epechein], which we shall have to explain in the Lucullus. Temeritatem ... turpius:  for these expressions, see II. 66, note. Praecurrere:  as was the case with the dogmatists. Paria momenta:  this is undiluted scepticism, and excludes even the possibility of the probabile which Carneades put forward.  For the doctrine cf.  II. 124, for the expression Euseb. Praep.  Evan. XIV. c. 4 (from Numenius) of Arcesilas, [Greek:  einai gar panta akatalepta kai tous eis ekatera logous isokrateis allelois], Sextus Adv.  Math. IX. 207 [Greek:  isostheneis logoi]; in the latter writer the word [Greek:  isostheneia] very frequently occurs in the same sense, e g Pyrrhon.  Hyp. I. 8 (add N.D. I. 10, rationis momenta)

Sec.46. Platonem:  to his works both dogmatists and sceptics appealed, Sextus Pyrrhon.  Hyp. I. 221 [Greek:  ton Platona oin hoi men dogmatikon ephasan einai, hoi de apo etikon, hoi de kata men ti aporetikon, kata de ti dogmatikon].  Stobaeus II. 6, 4 neatly slips out of the difficulty; [Greek:  Platon polyphonos on, ouch hos tines oiontai polydoxos]. Exposuisti:  Durand’s necessary em., approved by Krische, Halm, etc. for MSS. exposui. Zenone:  see Introd. p. 5.

NOTES ON THE FRAGMENTS.

BOOK I.

1. Mnesarchus:  see II. 69, De Or. I. 45, and Dict.  Biogr. ‘Antipater’; cf.  II. 143, De Off. III. 50.  Evidently this fragment belongs to that historical justification of the New Academy with which I suppose Cicero to have concluded the first book.
