II. Bardaisan's teaching; what supports his Entities in Space?

Again, let the party of Bardaisan be asked concerning those Entities which he speaks of, what supports these things of his [lv] also,² seeing that they are placed in a deserted and empty Space in which there is no breath of air supporting all, especially inasmuch as he mentions that there are both light and heavy Entities there? For Light is lighter than Wind and Wind than Fire, just as also Fire is lighter than Water. But light and heavy things cannot exist unitedly in one enclosure without the force of another [P. 53.] (supporting them).
