First, I think you do very well in capturing that sort of giddy excitement in having a belief undermined and the world turned upside down. I find it a rather addictive experience.
“It will touch each and every idea, and change it, and move on.”
Not necessarily.
Sometimes I am having a conversation and I say something like ‘we should stop dumping garbage.’ There are ways that I can believe this validly. I could mean that we should start a better recycling program. We should change the sort of consumer goods are available. We should make people more conscious of what sort of place they are creating. But I don’t know any of these arguments because this belief comes from the time before I learned to analyse and challenge beliefs, before I learned that I could fight back if a belief is challenged. Before I learned that I can see my belief in even the material world temporarily vanish without breaking. (It came back, which is nice because I like the material world.)
So there are residual beliefs, unless you systematically change all your beliefs at once only some will be changed. It is possible to have obsolete beliefs, which is really weird.
I looked up rejection therapy. It has a strong similarity to Stoicism, except that Stoicism requires not being attached to outcomes both in the social context and when interacting with inanimate objects. My confusion is with the implications of Rejection therapy. In Stoicism you do not become distressed because it is according to your nature as a human being to aim at certain things (friends, a warm house, a cow.). Aiming at those things in accordance with your nature is virtuous. Acquiring these things does not make you more or less virtuous. But with rejection therapy real rewards are offered which will not necessarily appear to those who have learned to deal with rejection.
I’m curious about this program. My main concern would be the dogmatic aspect, which I suppose is present in every ‘boot camp’ style program. I think that the strength of a university program over this sort of program is that university teaches you independent thinking whereas this could lead to dependence in those who did not have a strong sense of individuality. The difficulty would be accommodating those people.
