, etc.
_Antiochus_: this Bait. brackets. _Unum ... alterum_: cf. 44. _Esse quaedam
in visis_: it was not the _esse_ but the _videri_, not the actual existence
of a difference, but the possibility of that difference being infallibly
perceived by human sense, that the Academic denied. _Cernimus_: i.e. the
_probably_ true and false. _Probandi species_: a phenomenal appearance
which belongs to, or properly leads to qualified approval.

Sec.Sec.112--115. Summary. If I had to deal with a Peripatetic, whose
definitions are not so exacting, my course would be easier; I should
not much oppose him even if he maintained that the wise man sometimes
_opines_ (112). The definitions of the real Old Academy are more
reasonable than those of Antiochus. How, holding the opinions he does,
can he profess to belong to the Old Academy? (113) I cannot tolerate
your assumption that it is possible to keep an elaborate dogmatic
system like yours free from mistakes (114). You wish me to join your
school. What am I to do then with my dear friend Diodotus, who thinks
so poorly of Antiochus? Let us consider however what system not I, but
the _sapiens_ is to adopt (115).

Sec.112. _Campis ... exsultare ... oratio_: expressions like this are common
in Cic., e.g. _D.F._ I. 54, _De Off._ I. 61, _Orat._ 26; cf. also Aug.
_Cont. Ac._ III. 5 _ne in quaestionis campis tua eqitaret oratio_. _Cum
Peripatetico_: nothing that Cic. states here is at discord with what is
known of the tenets of the later Peripatetics; cf. esp. Sext. _A.M._ VII.
216--226. All that Cic. says is that he could accept the Peripatetic
formula, putting upon it his own meaning of course. Doubtless a Peripatetic
would have wondered how a sceptic _could_ accept his formulae; but the
spectacle of men of the most irreconcilable opinions clinging on to the
same formulae is common enough to prevent us from being surprised at
Cicero's acceptance. I have already suggested (n. on 18) that we have here
a trace of Philo's teaching, as distinct from that of Carneades. I see
absolutely no reason for the very severe remarks of Madvig on _D.F._ V. 76,
a passage which very closely resembles ours. _Dumeta_: same use in _N.D._
I. 68, Aug. _Cont. Ac._ II. 6; the _spinae_ of the Stoics are often
mentioned, e.g. _D.F._ IV. 6. _E vero ... a falso_: note the change of
prep. _Adhiberet_: the MSS. are confused here, and go Halm reads _adderet_,
and Bait. follows, while
