§6.9.1Κατὰ τὴν τῶν ὅλων φύσιν ἕκαστα περαίνεται· οὐ γὰρ κατ’ ἄλλην γέ τινα φύσιν ἤτοι ἔξωθεν περιέχουσαν ἢ ἐμπεριεχομένην ἔνδον ἢ ἔξω ἀπηρτημένην.
Each thing is accomplished in accordance with the nature of the whole; for it is not in accordance with any other nature, whether encompassing it from without, or contained within, or detached outside.
