Hyperstition is a new blog by Reza Negarestani, K-Punk, and a bunch of other people (and hosted by William Blaze) that merits a little more introduction. Hyperstitions are, in short, “fictions that make themselves real.”
K-Punk recommends Lemurian Time War and this article as an introduction to Hyperstion:
The situation is closer to the modern phenomenon of hype than to religious belief as we’d ordinarily think about it. Hype actually makes things happen, and uses belief as a positive power. Just because it’s not “real” now, doesn’t mean it won’t be real at some point in the future. And once it’s real, in a sense, it’s always been.”
Sounds very much like Grant Morrison’s idea of the hypersigil, especially when he talks about emergence.
