Can we Re-Build Civilisation after Collapse.

[River Song]

I have read Beyond Collapse at least twice. I don't know the other book.

In some respect the OP is correct. It will take a long time (if ever) to get back to some rudimentary levels of Civilization. Nonetheless if the alternative is outright anarchy, then we should at least try.

It's possible that sociologically we might be looking at some form of tribal unit. We might not have the raw materials to repair tools or make new ones, but never ever underestimate human ingenuity. We create afresh.

The only caveat I would make is that even if political and social units get smaller, they may have very little 'spunk' to keep them going.
