How does remoteness contribute to a society's cultural achievements and collapse?
Remoteness rarely contributes to a society's cultural achievements, as most societies depend upon the influence of other societies in order to prosper. Most architectural, literary, and governmental achievements are due, at least in part, to the influence of neighboring communities. Societies who come into contact with a large number of other communities through trade or other forms of interaction have wide and diverse cultural resources at their disposal. Most societies even tend to appropriate parts of the cultural apparatus of those whom they conquer. Roman culture is replete with literary, mythological, architectural, and governmental concepts that originated in Athens at the time of Rome's conquest of the prosperous city-state.
Remoteness can help a society remain stable and free from intrusion, but does not generally contribute to the creation of great cultural artifacts or achievements.
