The commoner Roman view: original righteousness wholly unowed, so a state of pure nature was possible
The more common view among the teachers of the Roman school goes another way. They hold that the righteousness and holiness of the first man was not only a supernatural gift, belonging to grace and not to nature, but also something wholly unowed to human nature, even innocent nature not yet sinful. So it would not have been at odds with God's wisdom, goodness and justice for man to be created without such righteousness.
That is why they count among man's possible states the state of pure nature, or, as they put it, of man in a purely natural condition. In that state, as they see it, man would be neither righteous nor unrighteous, neither guilty of any sin nor endowed with any grace.

XVII. Sed in diversum abit communior Doctorum Scholae Romanae sententia. Etenim existimant justitiam & sanctitatem, quae in primo homine fuit, non solum fuisse donum supernaturale, & quod ad naturam non ad gratiam pertinebat; sed etiam aliquid naturae humanae, quamvis innocenti & nondum peccatrici, prorsus indebitum: ita ut nihil repugnaret sapientiae, bonitati, & justitiae divinae hominem sine tali justitia creari. Unde est quod inter status hominis possibiles ponunt statum purae naturae, sive hominis, ut loquuntur, in puris naturalibus. In quo statu ex eorum mente, homo nec justus, nec injustus esset: nec ullius peccati reus nec etiam ulla gratia praeditus.
