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.
Yo dawg, the founding fathers were mostly the same rich ownership class that we see are today profiting off of political gridlocks. Our democracy is deeply imperfect thanks to the efforts of some of them, and I dont think democracy as a concept should be judged by success and failures in America. I don’t think OP needs to be qualified, it’s just a thought experiment.
Unironically Common Sense does attempt to explain this, and American founding fathers used this work as the template for our currently existing for of government.
