Without any scientific method, the only way to maintain dogmatic beliefs is through religious kind of absolutism. I also see no way to maintain these stories without an absolute authority like that. With a scientific method, dogmas are far more understandable and defensible (like the dogmas of thermodynamics or General Relativity, etc.,etc.*).
However, even still I see no way out of the inevitable drift of these truths becoming myths and the usual power, moral and social struggles slowly changing and adapting those myths into something more useful and pedagogic to the changing zeitgeists of the population...
* By "dogmas" I mean truths that are engraved in a really really important pedestal that no one has the right to just "meh" them. Scientific "dogmas" are those scientific truths that are so well established that you would really need something absolutely extraordinary to question them.
