The title is a bit over dramatic but, per the title, if you could contribute with one piece of knowledge to a book that every single individual should learn from in order to kickstart a civilization, what would be yours?
My personal choice would be the process of soap making, from scratch.
You mean like the civilization starter kit, when the lights go out, the manual for civilization, or the knowledge, how to build civiliazation in the aftermath of a cataclysm?
Interesting, Thanks. I will be reading these further.
Thought I should mention that the second link is not working for me.
