Questio de aqua et terra (41)

(41) [XVIII]. Sed talis instantia nulla est; procedit enim ex ignorantia nature homogeneorum et simplicium. Corpora enim homogenea et simplicia -- sunt homogenea ut aurum depuratum, et simplicia ut ignis et terra -- regulariter in suis partibus qualificantur omni naturali passione. (41) But this rejoinder is futile, since it proceeds from ignorance of the nature of homogeneous and rejected elementary bodies; for elementary bodies, too, are homogeneous. Homogeneous ones, such as refined gold, and elementary bodies, such as fire and earth, are uniformly qualified in all their parts, by any affection natural to them.
