St. Augustine on gravity

"I don't care to inquire why they cannot believe an earthly [human] body can be in heaven, while the whole earth is suspended on nothing.  For perhaps the world keeps its central place by the same law that attracts to its centre all heavenly bodies."

     St. Augustine, City of God XIII.18, trans. Dods.  Latin from CAG.

"nolo . . . quaerere, cur non credant terrenum esse posse corpus in caelo, cum terra uniuersa libretur in nihilo. fortassis enim de ipso medio mundi loco, eo quod in eum coeant quaeque grauiora, etiam argumentatio ueri similior habeatur."

I am unwilling to ask why they do not believe that an earthly [human] body can be in heaven, though the whole earth is suspended in [and from] nothing.  For as for that central place of the world:  by that thing [(quod) by which] all heavy [bodies] come together in it, so, it may be, a like proof of what is true [of it itself] may be had.

     "But let our adversaries a little more carefully consider this subject of earthly weight [(pondera ipsa terrena)], because it has important bearings, both on the ascension of the body of Christ, and also on the resurrection body of the saints."  Etc.
