Only semantically related, I remember reading this fiction book I now can't remember the name or even the premise of, but there were some discussions around this topic and there was one character who was basically arguing for a return to nature and basically tribal life and one of the other characters' argument against that was along the lines of how civilisation was basically to protect humans from nature and given what nature can be like that made a lot of sense to me XD
I think a lot of the problems with "civilised" people is that a lot of people (especially ones in charge of anything) have got egos too big to realise that they're stupid.
