Questio de aqua et terra (70)

(70) Ad cuius evidentiam sciendum quod, licet celum stellatum habeat unitatem in substantia, habet tamen multiplicitatem in virtute; propter quod oportuit habere diversitatem illam in partibus quam videmus, ut per organa diversa virtutes diversas influeret; et qui hec non advertit, extra limitem phylosophie se esse cognoscat. (70) And to make this evident, be it known that although the starry heaven has unity in substance, yet it has multiplicity in virtue; and that is why it needed the diversity in its parts which we observe, in order, by diverse organs, to pour down its diverse virtues; and let him who perceives not these things know that he is outside the threshold of philosophy.
