Ok, so why Liminal?
The idea of a liminal universe would have more of a humanitarian morality than the totalitarianism of the Anthropic Principles, which would seem to exclude everyone who is not able to access the information technology that is, supposedly, going to be our gateway to the conquest of all space and time. The Anthropic Principles suggest a kind of complacency, since mankind cannot do anything but take over the universe with consciousness, so there is no danger of us failing or of anything causing us sufficient harm to prevent this. A more humble approach would seem to make a great deal more sense, since the frenzy of excitement about the New Physics could be seen to echo the frenzy that followed the massive leaps in industrial technology, which, similarly, we did not think could feasibly cause us any harm. Social injustice, wars and cruelty could all be justified as furthering the selective aims of the anthropocentric models, whereas they have no place within a more liminal world where we bear in mind that what we do to the environment and to others has a direct bearing on ourselves as we are connected to others and to the environment in so many ways. The sense of our symbiosis with the planet is lost in the Anthropic Principles; we could say that the destruction of this planets resources is justified in order to jumpstart the inevitable move out into space.
So there.
