Finally, he gives us some Economics!

Well, kind of.

It's not often that I shall quote my textbook on International Trade (mine in the sense that I bought it off trademe, not that I wrote it) but as I just opened it (also not something I have done, or likely will do, often) this struck me:

God did not bestow all products upon all parts of the earth, but distributed His gifts over different regions, to the end that men might cultivate a social relationship because one would have need of the help of another. And so He called commerce into being, that all men might be able to have common enjoyment of the fruits of the earth, no matter where produced.
Libanius (AD 314-393), Orations (III) [quoted in Feenstra & Taylor, International Trade, p95]

Libanius was a pagan, but had a brain on him nonetheless; or so it would seem.
