Intriguing Book

In preparation for class, I've been reading David Sedley's Creationism and Its Critics in Antiquity. He explores how various thinkers from the earliest pre-socratics through Galen viewed the issue of created order. The greek word, kosmeo, means both the world itself, ie kosmos, but also order. What I have found most striking about the reading thus far is that at no point is there a discussion of ex nihilo creation. Creation out of nothing made no conceptual sense to them. Stuff, matter, has to be there to be ordered/ structured. Another fascinating point he raises is that there was no doctrinal appeal to some document to support a view about the cosmos. No ancient equivalent of inerrancy.
