§77. _Expresserat_: "had put into distinct shape". Cf. 7 and I. 19. _Exprimere_ and _dicere_ are always sharply distinguished by Cic., the latter merely implying the mechanic exercise of utterance, the former the moulding and shaping of the utterance by conscious effort; cf. esp. _Orat._ 3, 69, and _Ad Att._ VIII. 11, 1; also _De Or._ I. 32, _De Div._ I. 79, qu. by Krebs and Allgayer. The conj. of Dav. _exposuerat_ is therefore needless. _Fortasse_: "we may suppose". _Nec percipere_, etc.: cf. 68, n. _Tum illum_: a change from _ille, credo_ (sc. _respondit_), the _credo_ being now repeated to govern the infin. For the constr. after _ita definisse_ cf. _M.D.F._ II. 13 (who quotes exx.); also the construction with _ita iudico_ in 113. _Ex eo, quod esset_: cf. 18, n. _Effictum_: so Manut. for MSS. _effectum_, cf. 18. _Ab eo, quod non est_: the words _non est_ include the two meanings "is non existent," and "is different from what it seems to be"--the two meanings of _falsum_ indeed, see n. on 47. _Eiusdem modi_: cf. 40, 84. MSS. have _eius modi_, altered by Dav. _Recte ... additum_: the semicolon at _Arcesilas_ was added by Manutius, who is followed by all edd. This involves taking _additum_ = _additum est_, an ellipse of excessive rarity in Cic., see Madv. _Opusc._ I. 448, _D.F._ I. 43, _Gram._ 479 a. I think it quite possible that _recte consensit additum_ should be construed together, "agreed that the addition had been rightly made." For the omission of _esse_ in that case cf. Madv. _Gram._ 406, and such expressions as _dicere solebat perturbatum_ in 111, also _ita scribenti exanclatum_ in 108. _Recte_, which with the ordinary stopping expresses Cic.'s needless approval of Arcesilas' conduct would thus gain in point. Qy, should _concessit_ be read, as in 118 _concessisse_ is now read for MSS. _consensisse_? _A vero_: cf. 41. §78. _Quae adhuc permanserit_: note the subj., "which is of such a nature as to have lasted". _Nam illud ... pertinebat_: by _illud_ is meant the argument in defence of εποχη given in 67; by _nihil ... pertinebat_ nothing more is intended than that there was no _immediate_ or _close_ connection. Cf. the use of _pertinere_ in _D.F._ III. 55. _Clitomacho_: cf. n. on 59.
