Compare this 4T to others

[Kinser79]

I think you're misunderstanding what I mean by a Mega-Crisis. What I mean is that you'll have an entire saeculum of learching from one crisis to the next until it is resolved in a catastrophic 4T.

I mean catastrophic in the sense that the world order as we can possibly conceive of it now will be utterly destroyed. I also see lots of death being necessary to bring it about too.

According to my hypothesis the last one was the French Revolution and Napoleonic Wars.
