§129. _Quod coeperam_: in 128 at _veniamus nunc ad boni maique notionem_. _Constituendi_: n. on 114. _Bonorum summa_: cf. _D.F._ V. 21 and Madv. _Est igitur_: so in _De Div._ II. 8, _igitur_ comes fourth word in the clause; this is not uncommon in Cic., as in Lucretius. _Omitto_: MSS. _et omitto_, but cf. Madv. _Em._ 201 _certe contra Ciceronis usum est 'et omitto' pro simplici 'omitto,' in initio huius modi orationis ubi universae sententiae exempla subiciuntur per figuram omissionis_. _Relicta_: cf. 130 _abiectos_. Cic. generally classes Herillus (or Erillus as Madv. on _D.F._ II. 35 spells the name), Pyrrho and Aristo together as authors of exploded systems, cf. _D.F._ II. 43, _De Off._ I. 6, _T.D._ V. 85. _Ut Herillum_. MSS. have either _Erillum_ or _et illum_, one would expect _ut Herilli_. _Cognitione et scientia_: double translation of επιστημη. For the _finis_ of Herillus see Madv. on _D.F._ II. 43. _Megaricorum_: _Xenophanes_. Cic considers the Eleatic and Megarian schools to be so closely related as to have, like the schools of Democritus and Epicurus, a continuous history. The Megarian system was indeed an ethical development of Eleatic doctrine. Zeller, _Socrates_ 211. _Unum et simile_: for this see Zell. _Socr._ 222 sq, with footnotes, R. and P. 174 sq. _Simile_ ought perhaps to be _sui simile_ as in _Tim._ c. 7, already quoted on I. 30, see my note there and cf. I. 35. _Menedemo_: see Zeller _Socr._ 238, R. and P. 182. The _Erctrian_ school was closely connected with the Megarian. _Fuit_: = _natus est_, as often. _Herilli_: so Madv. for _ulli_ of MSS. §130. _Aristonem_: this is Aristo of Chios, not Aristo of Ceos, who was a Peripatetic; for the difference see R. and P. 332, and for the doctrines of Aristo the Chian _ib._ 358, Zeller 58 sq. _In mediis_: cf. I. 36, 37. _Momenta_ = _aestimationes_, αξιαι in 36, where _momenti_ is used in a different way. _Pyrrho autem_: one would expect Pyrrhoni as Dav. conj., but in 124 there is just the same change from _Pyrrhoni_ to _Xenocrates_. Απαθεια: Diog. IX. 108 affirms this as well as πραιοτης to be a name for the sceptic τελος, but the name scarcely occurs if at all in Sext. who generally uses αταραξια, but occasionally μετριοπαθεια; cf. Zeller 496, R. and P. 338. Απαθεια was also a Stoic term. _Diu multumque_: n. on I. 4.
