7.

Sec.26. _Quid quod si_: Goer., outrageously reads _quid quod si, si_.
_Tollitur_: the verb _tollere_ occurs as frequently in this sense as
[Greek: anairein] does in Sextus. _Lux lumenque_: Bentl. _dux_ The
expression _dux vitae_ is of course frequent (cf. _N.D._ I. 40, _T.D._ V. 5
and Lucretius), but there is no need to alter. _Lux_ is properly natural
light, _lumen_ artificial, cf. _Ad Att._ XVI. 13, 1. _lumina dimiseramus,
nec satis lucebat_, D.F. III. 45 _solis luce ... lumen lucernae_. There is
the same difference between [Greek: phos] and [Greek: phengos], the latter
is used for the former ([Greek: phengos heliou]) just as _lumen_ is for
_lux_ (_si te secundo lumine his offendere_--_Ad Att._ VII. 26, 1) but not
often _vice versa_. Trans. "the luminary and the lamp of life," and cf.
Sext. _Adv. Math._ VII. 269 where the [Greek: phantasia] is called [Greek:
phengos]. _Finis_: so in the beginning of the _Nicom. Eth._ Aristot.
assumes that the actual existence of human exertion is a sufficient proof
that there is a [Greek: telos]. _Aperta_: a reminiscence of the frequently
recurring Greek terms [Greek: ekkalyptein, ekkalyptikos] etc., cf. Sextus
_passim_, and _D.F._ I. 30. _Initium ... exitus_ = [Greek: arche ...
telos]. _Tenetur_: MSS. _tenet_, the nom. to which Guietus thought to be
_ratio_ above. [Greek: Apodeixis]: cf. the definition very often given by
Sext. e.g. _Pyrrh. Hyp._ II. 143 [Greek: logos di' homologoumenon lemmaton]
(premisses) [Greek: kata synagogen epiphoran] (conclusion) [Greek:
ekkalypton adelon], also Diog. VII. 45, [Greek: logon dia ton mallon
katalambanomenon to hetton katalambanomenon perainonta] (if the reading be
right).

Sec.27. _Notio_: another trans. of [Greek: ennoia]. _Conclusisse_: although
the Greeks used [Greek: symperasma] instead of [Greek: epiphora] sometimes
for the conclusion of the syllogism, they did not use the verb [Greek:
symperainein] which has been supposed to correspond to _concludere_. It is
more likely to be a trans. of [Greek: synagein], and _conclusum argumentum_
of [Greek: synaktikos logos], which terms are of frequent occurrence.
_Rationibus progredi_: to a similar question Sextus answers, [Greek: ouk
estin anankaion tas ekeinon] (the dogmatists) [Greek: dogmatologias
probainein, plasmatodeis hyparchousas] (_Adv. Math._ VIII. 367).
_Sapientiae ... futurum est_: for the dat. with _facio_ and _fio_ see Madv.
_Gram._ 241, obs. 5, _Opusc._ I. 370, _D.F._ II. 79, and
