_: Halm with one MS.
(G) gives _praescriptione_, which is in II. 140, cf. also _praescriberet_
above. The phrase is Antiochean; cf. _prima constitutio naturae_ in _D.F._
IV. 15. _Aequitas_: not in the Roman legal sense, but as a translation of
[Greek: epieikeia]. _Eaeque_: so Halm for MSS. _haeque_, _haecque_. Of
course _haecque_, like _hicque_, _sicque_, would be un-Ciceronian.
_Voluptatibus_: a side blow at the Epicureans. _Forma_ see n. on 33.

Sec.Sec.24--29. Part III of Varro's Exposition. Antiochus' _Physics_.
Summary. All that is consists of force and matter, which are never
actually found apart, though they are thought of as separate. When
force impresses form on the formless matter, it becomes a formed entity
([Greek: poion ti] or _quale_)--(24). These formed entities are either
_primary_ or _secondary_. Air, fire, water, earth are primary, the two
first having an active, the two last a passive function. Aristotle
added a fifth (26). Underlying all formed entities is the formless
matter, matter and space are infinitely subdivisible (27). Force or
form acts on the formless matter and so produces the ordered universe,
outside which no matter exists. Reason permeates the universe and makes
it eternal. This Reason has various names--Soul of the Universe, Mind,
Wisdom, Providence, Fate, Fortune are only different titles for the
same thing (28, 29).

Sec.24. _Natura_: this word, it is important to observe, has to serve as a
translation both of [Greek: physis] and [Greek: ousia]. Here it is [Greek:
ousia] in the broadest sense, all that exists. _In res duas_: the
distinction between Force and Matter, the active and passive agencies in
the universe, is of course Aristotelian and Platonic. Antiochus however
probably apprehended the distinction as modified by the Stoics, for this
read carefully Zeller, 135 sq., with the footnotes. The clearest view of
Aristotle's doctrine is to be got from Schwegler, _Handbook_, pp 99--105.
R. and P. 273 sq. should be consulted for the important coincidence of
Force with logical _genus_ ([Greek: eidos]), and of Matter ([Greek: hyle])
with logical _differentia_ ([Greek: diaphora]). For the _duae res_, cf.
_D.F._ I. 18. _Efficiens ... huic se praebens_: an attempt to translate
[Greek: to poioun] and [Greek: to paschon] of the _Theaetetus_, [Greek: to
othen] and [Greek: to dechomenon] of the _Timaeus_ (50 D). Cic. in _Tim._
has _effice
