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.
No person can grant you rights. Rights are those things you are capable of doing for yourself providing it doesn’t infringe on the liberty of another. You are physically capable of speaking and thinking. Of moving, of tending to property, of attempting to defend yourself, your family, those who request assistance, and your property. You can build anything you have the knowledge and means to build. You have the right to determine your own safety, this includes what you ingest and any precautions you opt out of. What is not your rights are anything that limits the liberties and rights of another person or property.
“Your rights are what you can take and defend by yourself” is the logic of sociopaths and warlords, not civilization.
