| (84) Ad quintum, cum dicitur quod aqua est corpus imitabile orbis lune, et per hoc concluditur quod debeat esse ecentrica, cum orbis lune sit ecentricus, dico quod ista ratio non habet necessitatem; quia licet unum adimitetur aliud in uno, non propter hoc est necesse quod imitetur in omnibus. Videmus ignem imitari circulationem celi, et tamen non imitatur ipsum in non moveri recte, nec in non habere contrarium sue qualitati; et ideo ratio non procedit. | (84) As to the fifth, when it is said that water is a body that imitates the orbit of the moon, and therefrom the conclusion is drawn that it must needs be excentric, since the orbit of the moon is excentric, I say that that argument carries no necessity; for though one thing should imitate another in one respect, it is not therefore necessary that it should imitate it in every respect. We see that fire imitates the circulation of the heavens, and yet it does not imitate it in not moving in a straight line, or in not having any contrary to its quality; and so the argument does not run. |
