At this point I don't really have an opinion about concepts such as this. I can see how it would be reasonable to suppose "larger forces at work" in the collective organism of human history. But I can also see how a case might be made for a more "dynamic" conception of these larger forces analogous to wind currents or water turbulence, etc.
Not really an area I have spent much thought on and I can really only idly speculate.
