§110. _Ut illa_: i.e. the _decreta_ implied in the last sentence. Some MSS. have _ille_, while Dav. without necessity gives _alia_. _Sic hoc ipsum_: Sext. then is wrong is saying (_P.H._ I. 226) that the Academics διαβεβαιουνται τα πραγματα ειναι ακαταληπτα, i.e. state the doctrine dogmatically, while the sceptics do not. _Cognitionis notam_: like _nota percipiendi_, _veri et falsi_, etc. which we have already had. _Ne confundere omnia_: a mocking repetition of Lucullus phrase, cf. 58. _Incerta reddere_: cf. 54. _Stellarum numerus_: another echo of Lucullus; see 32. _Quem ad modum ... item_: see Madv. on _D.F._ III. 48, who quotes an exact parallel from _Topica_ 46, and _sicut ... item_ from _N.D._ I. 3, noting at the same time that in such exx. neither _ita_ nor _idem_, which MSS. sometimes give for _item_, is correct. §111. _Dicere ... perturbatum_: for om. of _esse_ cf. 108, 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. §§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).
