Physical good includes nature itself and its faculties, and every advantage and gift that perfects nature apart from the character of virtue, of whatever kind, whether it springs from natural principles or is granted by God above nature.
So this good is called physical, or the good of nature, not to set it against supernatural good, but only to set it against moral good as just described.
Latin
III. Ad bonum autem istud quod Physicum dicitur, pertinet tum natura ipsa, & ejus facultates, tum commoda & dona quaecunque illam extra rationem virtutis perficiunt, cujuscunque tandem generis sint, sive ex principiis naturae oriantur, sive supra naturam a Deo concedantur. Ac propterea hoc bonum non dicitur bonum Physicum, seu naturae, ut per id opponatur bono supernaturali, sed solum ut opponatur bono morali, quod modo descriptum est.
