La rectitud de todas las cosas es una y la misma

M. Quid ergo consequi existimas de ipsis rectitudinibus? Sunt aliae ab invicem, aut est una et eadem omnium rectitudo? D. Supra concessi quia si ideo plures sunt rectitudines, quoniam plures sunt res in quibus considerantur: necesse est eas existere et variari secundum res ipsas; quod nequaquam fieri demonstratum est. Quapropter non ideo sunt plures rectitudines, quia plures sunt res in quibus sunt. M. An habes aliquam aliam rationem, cur tibi plures esse videantur, praeter ipsam rerum pluralitatem? D. Sicut istam nullam esse cognosco, ita nullam aliam inveniri posse considero. M. Una igitur et eadem est omnium rectitudo. D. Sic mihi fateri necesse est. (Anselmus, De veritate, 13)

T. So what conclusion do you think follows regarding these rightnesses? Are they different from one another, or is there one and the same rightness of all things? S. I conceded previously that if there is more than one rightness simply because there is more than one thing in which rightness is seen to be, then it necessarily follows that these rightnesses exist and change in accordance with those things. But this was proven not at all to happen. Therefore, it is not the case that there is more than one rightness simply because there is more than one thing in which there is rightness. T. Do you have any other reason for supposing that there is a plurality of rightnesses except that there is a plurality of things? S. Just as I recognize that the argument from a plurality of things is faulty, so I see that no other argument can be found. T. Therefore, the rightness of all things is one and the same. S. Yes, I have to agree. (http://www.jasper-hopkins.info/DeVeritate.pdf)
