Thanks to InfoGalactic, I learned the other day a bit about Chaos Magic. I had searched on “egregor” – the Greek for “watcher,” a topic of some interest to me – and found out that it is a term of art in that discussion. In Chaos Magic, an egregor is an artificial spirit, created by a magician as at first a heuristic hypostatization, a “thought form,” devised for his own convenient internal usages, of some nexus of impulses within himself – sometimes nice, sometimes not so nice (as, say, a besetting temptation) – so as to identify and, above all, simply *notice it,* and thus address it more aptly; and then at some point publicly promulgated, so that it then engages the interest and attention of other practitioners, who find it useful and adopt it for their own internal operations, so that it then informs their activities. A meme, in other words, but a meme that has some intrinsic characteristics that lend it suasive and informative powers, so that it can seem to take on a life of its own, and become the apparent animating spirit of a whole group of people. Widely disparate people, not communicating with each other at all (so far as we can know), can evoke the response to current events of an egregor that has possessed them without any outward coordination, and in a unison of spirit and even of diction that is truly wonderful, even spooky.
There is much truth in this notion. Consider, e.g., anthropogenic global warming. Or transsexuality. Or Trump Derangement Syndrome. Or Communism. Or for that matter any fad or trend or notion, any ideology, that has little objective correlate or reason outside the merely social world.
