§106. _Memoria_: cf. 22. _Polyaenus_: named _D.F._ I. 20, Diog. X. 18, as one of the chief friends of Epicurus. _Falsum quod est_: Greek and Latin do not distinguish accurately between the _true_ and the _existent_, the _false_ and the _non existent_, hence the present difficulty; in Plato the confusion is frequent, notably in the _Sophistes_ and _Theaetetus_. _Si igitur_: "if then recollection is recollection only of things perceived and known." The dogmatist theory of μνημη and νοησις is dealt with in exactly the same way by Sext. _P.H._ II. 5, 10 and elsewhere, cf. also Plat _Theaet._ 191 sq. _Siron_: thus Madv. on _D.F._ II. 119 writes the name, not _Sciron_, as Halm. _Fateare_: the em. of Dav. for _facile_, _facere_, _facias_ of MSS. Christ defends _facere_, thinking that the constr. is varied from the subj. to the inf. after _oportet_, as after _necesse est_ in 39. For _facere_ followed by an inf. cf. _M.D.F._ IV. 8. _Nulla_: for _non_, cf. 47, 103. §107. _Fiet artibus_: n. on 27 for the constr., for the matter see 22. _Lumina_: "strong points." Bentl. boldly read _columina_, while Dav. proposed _vimina_ or _vincula_. That an em. is not needed may be seen from _D.F._ II. 70. _negat Epicurus (hoc enim vestrum lumen est)_ _N.D._ I. 79, and 43 of this book. _Responsa_: added by Ernesti. Faber supplies _haruspicia_, Orelli after Ern. _haruspicinam_, but, as Halm says, some noun in the plur. is needed. _Quod is non potest_: this is the MSS. reading, but most edd. read _si is_, to cure a wrong punctuation, by which a colon is placed at _perspicuum est_ above, and a full stop at _sustineat_. Halm restored the passage. _Habuerint_: the subj. seems due to the attraction exercised by _sustineat_. Bait. after Kayser has _habuerunt_. _Positum_: "when laid down" or "assumed."
