Too many annoying metaphors
I think I'm gonna junk 'em all and just refer to my "self" and my "self-limitations".
I pretty much still feel this way.
However, different metaphors appeal to different people. I think that adding more layers to the metaphor (a dungeon, a desert, etc) really just makes it less effective and less clear.
If someone can't grasp the prison metaphor, it's certainly not the metaphor that's going to lead them to awareness of how malleable their perceptions actually are once they take control of them.
The Black Iron Prison makes perfect sense to me, even though it's an imperfect metaphor. Unfortunately, all metaphors are imperfect, because they're metaphors and not literal descriptions. It takes a certain level of mental flexibility and imagination for any metaphor to make sense. I suspect that the people who immediately "get" the BiP are people who have already considered the concepts presented by it, so the metaphor falls into place with something they'd started to think about but didn't have a cohesive structure for.
Rat, there are a lot of published works that are designed to bring the reader to a philosophy that is not fully explained in the book or pamphlet that introduces them to it. Does a Jack Chick comic fully explain Christianity? Does a pamphlet about yoga tell the reader everything about yoga? It's perfectly reasonable to say to someone who has read the BiP booklet, "Here, that was just a small collection of essays; to learn more about it, read the wiki". I mean, fuck, www.principiadiscordia.com
are printed RIGHT ON THE FRONT COVER. If that doesn't make it sufficiently clear that it's introductory/promotional material, I don't know what would.
I'm going to confess that I'm not blown away by the BiP metaphor. I think it's useful for people who have just started thinking critically, but that once you're past that point it's too limiting to serve for very much further development. It's basically just what it seems intended to be; good for the jailbreak. Once you've started breaking down your jail and are ready to begin rearranging the pieces, it's probably time to move on to other metaphors, or to simply ditch metaphors altogether for a while.
Metaphors are most useful to get people to think of things in new ways. It's not a very good idea to get stuck in them, whether from the inside trying to hold on to one you've outgrown, or from the outside trying to analyze one that doesn't work for you.
