It is obvious that human kind needs a solution, but part of the problem is that it is so difficult to think creatively about the nature of this solution or the terms in which it would be defined.
Promethean messianism posits that the solution must be the greatest possible rational desire...not -inconceivable-, like the heaven of the medievals, but -difficult- to conceive.
And the difficulty is not just intellectual, it is also libidinal: we are ashamed to conceive it. We cannot bear to, it seems absurd and disgusting, because our sense of self is ruled by a shame that outlines our sense of what is disgusting, riduclous, passé, pretentious. We foreclose its conception in the name of a sort of frightened sense of honor.
