Nature is everything, together. Marcus Aurelius 6.9
Unnatural
events? Impossible, for Marcus Aurelius.
Κατὰ
τὴν τῶν ὅλων φύσιν ἕκαστα περαίνεται·
οὐ γὰρ κατ’ ἄλλην γέ τινα φύσιν ἤτοι
ἔξωθεν περιέχουσαν ἢ ἐμπεριεχομένην
ἔνδον ἢ ἔξω ἀπηρτημένην.
Everything
achieves its final form in keeping with the nature of all things
together, for there is no other nature containing it, whether we look
within the whole of all things or in some realm beyond it.
