“The Indus civilization has challenged scholars’ understanding since its discovery some eighty years ago, and in recent years the application of systematic and problem-orientated research, coupled with much new and unexpected data, has overturned many previous interpretations.”

Technopagans at the End of History (1998)
Context: 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!

1961, Address to ANPA
Context: I want to talk about our common responsibilities in the face of a common danger. The events of recent weeks may have helped to illuminate that challenge for some; but the dimensions of its threat have loomed large on the horizon for many years. Whatever our hopes may be for the future — for reducing this threat or living with it — there is no escaping either the gravity or the totality of its challenge to our survival and to our security — a challenge that confronts us in unaccustomed ways in every sphere of human activity.
This deadly challenge imposes upon our society two requirements of direct concern both to the press and to the President — two requirements that may seem almost contradictory in tone, but which must be reconciled and fulfilled if we are to meet this national peril. I refer, first, to the need for a far greater public information; and, second, to the need for far greater official secrecy.
