[A]ll religions need a ‘book’. I have been working under that premise for over a decade. Once you have a book, philosophy doesn’t float. You have an authoritarian position to refer to. Debate over that position creates invention in the minds of those who are interested.
If the book is very good, then the results are self organizing. If you have a book and advocates, then you have political means. If you have a book, advocates and members, then you political power. If you have political power you can institute your ideas. If your book morally condones violence in the pursuit of your ideas, you have an eternal irrevocable advantage independent of current circumstance.
The problem for the west is that we have never had a book. Plato failed. The monarchs ruled by tradition. The church spoke in allegory. Smith Hume and Jefferson wrote advice not rules, and they created the catastrophic error that the near universal aristocratization of the English could have the same breadth of application as the doctrine of the church.
