Wait lets back up und make sure we understand each others point:
The way I see your perspective: you say that individual role in history is rather unimportant, we are all just part of some complex process wich leads to an inevitable progress through forces mostly outside individual control. Is it fair representation or did I miss something?
My perspective is: in the end it's individuals/groups who make specific things that contribute to progress, while sometimes the individuals might be replaceable, they sometimes also leave their individual marks on the events or theories they create (Freund vs. Jung for example - if Jung was more influential we might have quite different psychology). And even if they are replaceable, in the end it's still individuals that have to make things happen.
