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.

      IIRC it’s a pretty skinny book, though, so it’s probably light on important details.
