Hi Tetrapod,
Whether the account of the Tower of Babel and the dispersion of the populace is literal history or not, it contains what I consider an enormously insightful statement:
Gen 11:6..."The LORD said, 'If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them.' "
As languages around the world differ, so do cultural practices and types of governments. What if the entire world was united in language, culture, and economy under a centralized government? What if all the great minds of the world were able to work together, unhindered by differences in not only their own political and social views, but also the ideologies of heads of governments? What if everyone was united in common goals and unhindered by cultural, political, and communication barriers? What if there was no war or competition between nations? As I read it here, Genesis says, "nothing will be impossible for them." Diseases would be cured, quality lifespans would be lengthened, perhaps indefinitely, all the frontiers could be explored and understood, even controlled--mankind would become its own god. That may sound wonderful, like utopia. That's assuming, of course, we get and remain on the right track. But what if we take a wrong turn? What if we go in a destructive direction without realizing it? And, of course, in this kind of world, there would be no place for non-conformist thinking. So, the very things that hinder man's progress can also serve as a check against self-destruction.
People, when working together without barriers, are capable of great things. But without proper direction, "great" in what way? Ultimately, who's going to decide?
