Sec.Sec.43--45. Summary. The sceptics ought not to _define_, for (1) a
definition cannot be a definition of two things, (2) if the definition
is applicable only to one thing, that thing must be capable of being
thoroughly known and distinguished from others (43). For the purposes
of reasoning their _probabile_ is not enough. Reasoning can only
proceed upon _certain_ premisses. Again to say that there are false
sensations is to say that there are true ones; you acknowledge
therefore a difference, then you contradict yourselves and say there is
none (44). Let us discuss the matter farther. The innate clearness of
_visa_, aided by reason, can lead to knowledge (45).

Sec.43. _Horum_: Lamb. _harum_; the text however is quite right, cf. Madv.
_Gram._ 214 b. _Luminibus_: cf. 101. _Nihilo magis_: = [Greek: ouden
mallon], which was constantly in the mouths of sceptics, see e.g. Sext.
_P.H._ I. 14. _Num illa definitio ... transferri_: I need hardly point out
that the [Greek: horos] of the Academics was merely founded on probability,
just as their "truth" was (cf. n. on 29). An Academic would say in reply to
the question, "probably it cannot, but I will not affirm it." _Vel illa
vera_: these words seem to me genuine, though nearly all editors attack
them. _Vel_ = "even" i.e. if _even_ the definition is firmly known, the
thing, which is more important, must also be known. In _illa vera_ we have
a pointed mocking repetition like that of _veri et falsi_ in 33. _In
falsum_: note that _falsum_ = _aliam rem_ above. For the sense cf. Sext.
_P.H._ II. 209 [Greek: mochtherous horous einai tous periechontas ti ton me
prosonton tois horistois], and the schoolmen's maxim _definitio non debet
latior esse definito suo_. _Minime volunt_: cf. 18. _Partibus_: Orelli
after Goer. ejected this, but _omnibus_ hardly ever stands for _omn.
rebus_, therefore C.F. Hermann reads _pariter rebus_ for _partibus_. A
little closer attention to the subject matter would have shown emendation
to be unnecessary, cf. 42 _dividunt in partis_, _T.D._ III. 24, where
_genus_ = division, _pars_ = subdivision.

Sec.44. _Impediri ... fatebuntur_: essentially the same argument as in 33 at
the end. _Occurretur_: not an imitation of [Greek: enantiousthai] as Goer.
says, but of [Greek: apantan], which occurs very frequently in Sext.
