Not much is left to the imagination.
Were we "more moral" then and are we "anything goes" now? Does nothing shock us? Is nothing sacred or off limits or out of bounds?
Who decides what a society becomes? Is there a "leader" with charisma that everyone automatically follows? Is it by mutual consent? We take different paths in our lifetimes...individually and collectively. Who takes over as leader? Why do we follow some people and not others?
