Good point. That's actually the case for both philosophies. The major difference in ancient thought was that ideas already have their own independent existence in the world and that people "receive" them by getting in tune with the universe. The idea is identical to the thing.

Modern thought involves an internalization of ideas to humans, producing a split between things and ideas. Ideas are the domain of thought and things are "in the world". This distinction is necessary to do OO, as far as I can tell. Programming is at least at the abstraction level of Enlightenment thought. :)
