I don't really think they were barbarians in any very interesting sense, just that if there's some contemporary perspective from which you could have seen them that way it would be from a Greek cultural perspective. My point was more just that anything Rome might have lacked culturally was basically right next door in Greece and even familiar to educated Romans - it's silly to skip over Greece and denigrate the Romans from some "Asian" perspective when a substantial amount of that asian stuff derived from Greece in the first place.

And I think the Romans knew they had the strengths you describe and the weaknesses I describe - and in the case of some Romans explicitly preferred it that way. Again that's not well described as a society that is "cut off" from anything.
