I would also note how the apocalypse archetype can be seen in Deleuze and Guatarri’s three syntheses as described by Ian Buchannan in his reader’s guide to The Anti-Oedipus: Capitalism and Schizophrenia: the connective, the disjunctive, and the conjunctive. With the connective we have a standing order in a state of becoming, what could be seen as the intro in a normal plot line. With the disjunctive, we see the crisis at work: that which elevates the intensity while activating an underlying chaos. And in the conjunctive we can see the denouement which lands into a new standing order: an uneasy synthesis still haunted by the disjunctive phase.
My point here is that if we can see such a pattern (an archetype (in the work of such thinkers as D&G, we have to assume that (as Jung would argue (the structure is not just rooted in our minds, but our very biology and natural environments. And this seems to me to be the one thing Koester misses out on. While he does an excellent job of explaining the Book of Revelations in secular terms, he, thus far, misses out on the natural influences that might be at play, those rooted in our evolution as a species.
For instance, we could look at the changing of the seasons which hint at an emerging of life that leads to chaos (becomes more complicated (then descends into death that, in turn, leads to a new emergence of life: a new standing order. Or we could look at the process of life that, as we get older, descends into chaos and destruction that then (via death (leads to a new standing order.
The main point here is to look at the perfectly natural and psychologically internal patterns (much like the Oedipus Complex (that might lead to John writing the Book of Revelations –even if they must be overcome (as a form of over coding (much as D&G attempted to do with the Anti-Oedipus.
