the αυταρκεις, men sufficient for themselves, '_in se toti teretes atque rotundi_'. We have here a reminiscence of the Stoic doctrine about the wise man, whose happiness is quite independent of everything outside himself, and is caused solely by his own virtue. Cicero represents the same Stoic theory in Lael. 7. Cf. Juv. Sat. 10, 357-362; also Seneca, De Cons. Sap. VIII, De Prov. I. 5. -- A SE IPSI: 'themselves from themselves,' so in 78 _se ipse moveat ... se ipse relucturus sit_; 84 _me ipse consolabar_. Expressions like _a se ipsis_ are quite uncommon in Cicero. Cf. n. on Lael. 5 _te ipse cognosces_; also see below, 38 _se ipsa_ 78 _se ipse_. -- NATURAE NECESSITAS: 'the inevitable conditions of nature.' Cf. 71 _quid est tam secundum naturam quam senibus emori?_ -- AFFERAT: subjunctive because _nihil quod_ = _nihil tale ut_. A 320, _a_; G. 633, 634; H. 503, I. -- QUO IN GENERE: _sc. rerum_; with this phrase the defining genitive is commonly omitted by Cicero. So below, 45 _in eo genere_. -- UT ... ADEPTAM: notice the chiasmus. -- EANDEM: _idem_ is used in the same way, to mark an emphatic contrast in 24, 52, 68, 71. -- ADEPTAM: this is probably the only example in Cicero of the passive use of _adeptus_, which occurs in Sallust, Ovid, Tacitus, etc.; and in this passage the use cannot be looked on as certain, since one of the very best and several of the inferior MSS. read _adepti_. Cicero, however, uses a good many deponent participles in a passive sense (cf. below, 59 _dimensa_; 74 _meditatum_; see also a list, Roby, 734), and some of them occur very rarely. Thus _periclitatus, arbitratus, depastus_ as passives are found each in only one passage. -- INCONSTANTIA: 'instability', 'inconsistency'. _Constantia_, unwavering firmness and consistency, is the characteristic of the wise man; cf. Acad. 2, 23 _sapientia ... quae ex sese habeat constantiam_; also Lael. 8 and 64.
