I have looked at the thread and the book sounds interesting. I particularly wonder about conspiracy theories as myths which are influential. Of course, they compete with so many myths in the context of relativism.

At one point, the myths arising from Christianity were so strong. In particular, the idea of apocalypse had so much influence, including on Ronald Reagan. This all came into play with so much expectation of the end of the world at 2000. The end didn't happen but 20 years on the world seems more fragile than end. The reality of climate change may hover as the major threat of an 'inevitable'. I remember when discussing the postmodernist ideas of 'end of history' in conjunction with the threat of the end of civilisation on this forum some saw such an end as almost inevitable. Part of the problem is that so many different systems of thought and worldviews contribute to mythic beliefs in 'doom and gloom' impact and this may be having a negative impact on intersubjective thinking and actions in the world.
