Human beings are co-partners with deity in the project of being. This is the basis of all magic. - Terence McKenna

Like fish in water, people in a culture swim in the virtually invisible medium of culturally sanctioned yet artificial states of mind.

Mark mentioned the vector of virtual reality, nanotechnology, global communications—it's clear that we're moving toward, if not the Eschaton itself, then some kind of historical echo of it, in simulation, that, for all practical purposes, will be the same thing, as far as the impact it has on our lives.
For example, you could doubt my much-vaunted prediction that the world will become unrecognizable by 2012; but do you doubt for a moment that by 2012, every major religion on Earth will have vast simulations of its eschatological vision for you to wander in and try out—so that you can look in on Nirvana.com, or lope over to the Celestial City, or look in on Sufi paradise? I mean, religious ontologies will be marketed like beers! And will be made as realistic and compelling as possible!
Well, then, who is to say what is real and what is not? "Real" is a distinction of a naïve mind, I think. We're getting beyond that. I mean, naïve empiricism worked well enough, until the discoveries of quantum physics seventy or eighty years ago revealed the hideous secret that the bedrock of reality is a funhouse basement!

No one knows enough to worry.
