Are you tired of the end of the world yet? I am, but I've been hearing about it since Comet Kohoutek back in 1973 and I decided at about the time Y2K came and went not with a bang but a whimper that if the world is coming to an end it can probably do so without my worry or supervision.
Lots of people these days are talking about December 21, 2012 -- the end of the Mayan Long Count Calendar -- as the start of Armageddon or a global shift in consciousness, either of which is guaranteed to create stunning changes in our lives. Some people are excited because they are headed for a quick trip to heaven while the rest of us get to hang around and suffer for our sins; others are excited because the Age of Aquarius is upon is and things are about to get really groovy up in here.
John Michael Greer talks about that and more in Apocalypse Not: Everything You Know About 2012, Nostradamus and the Rapture is Wrong. Greer traces the concept of the apocalypse from its invention by Zarathustra, the founder of Zoroastrianism, in the 7th century B.C.E through to the present day. Greer has a gift for taking complex concepts and making them accessible, clearly explaining ten centuries of apocalyptic thinking in 178 pages that despite the serious subject matter are laugh-out-loud funny in spots.
It's not the end of the world as we know it and I feel fine.
