[φύσις is here (as the apodosis of the clause shows) as well as in the next section, used as a somewhat more vague equivalent for οὐσία, not, as Newman contends in an omitted note, for ‘person,’ a use which is scarcely borne out by the (no doubt somewhat fluctuating) senses of φύσις in the passages quoted by him from Alexander (in Theod. H. E. i. 4, cf. Origen’s use of οὐσία, Prolegg. ch. ii. §3 (2) a) and Cyril c. Nest. iii. p. 91. φύσις and οὐσία are nearly equivalent in the manifesto of Basil of Ancyra, whom Ath. has in view here, see Epiph. Hær. 73. 12–22.]
