Sec.25. Bene facis:  passim in comedy, whence Cic. takes it; cf. D.F. III. 16, a passage in other respects exceedingly like this. Rhetoricam:  Huelsemann conj. ethicam, which however is not Latin.  The words have no philosophical significance here, but are simply specimens of words once foreign, now naturalised. D.F. III. 5 is very similar.  Cic.’s words make it clear that these nouns ought to be treated as Latin first declension nouns; the MSS. often give, however, a Gk. accus. in en. Non est vulgi verbum:  it first appears in Theaet. 182 A, where it is called [Greek:  allokoton onoma]. Nova ... facienda:  = imponenda in D.F. III. 5. Suis utuntur:  so D.F. III. 4. Transferenda:  transferre = [Greek:  metapherein], which is technically used as early as Isocrates.  See Cic. on metaphor, De Or. III. 153 sq., where necessitas is assigned as one cause of it (159) just as here; cf. also De Or. III. 149. Saecula:  the spelling secula is wrong; Corss.  I. 325, 377.  The diphthong bars the old derivations from secare, and sequi. Quanto id magis:  Cic. is exceedingly fond of separating tam quam ita tantus quantus, etc., from the words with which they are syntactically connected, by just one small word, e.g. Lael. 53 quam id recte, Acad. II. 125 tam sit mirabilis, II. 68 tam in praecipitem; also D.F. III. 5 quanto id nobis magis est concedendum qui ea nunc primum audemus attingere.

Sec.26. Non modo rerum sed verborum:  cf. 9. Igitur picks up the broken thread of the exposition; so 35, and frequently. Principes ... ex his ortae:  the Greek terms are [Greek:  hapla] and [Greek:  syntheta], see Arist. De Coelo, I. 2 (R. and P. 294).  The distinction puzzled Plutarch (quoted in R. and P. 382).  It was both Aristotelian and Stoic.  The Stoics (Zeller, 187 sq.) followed partly Heraclitus, and cast aside many refinements of Aristotle which will be found in R. and P. 297. Quasi multiformes:  evidently a trans. of [Greek:  polyeideis], which is opposed to [Greek:  haplous] in Plat. Phaedr. 238 A, and often.  Plato uses also [Greek:  monoeides] for unius modi; cf.  Cic. Tim. ch.  VII., a transl. of Plat. Tim. 35 A. Prima sunt:  primae (sc. qualitates) is the needless em. of Walker, followed by Halm. Formae = genera, [Greek:  eide].  The word is applied to the four elements themselves, N.D. I. 19; cf. also quintum genus below, and Topica, 11—­13.  A good view of the history of the doctrine of the four elements may be gained from the section of Stob. Phys., entitled [Greek:  peri archon kai stoicheion kai tou pantos].  It will be there seen that Cic. is wrong in making initia and elementa here and in 39 ([Greek:  archai]
