The first Christian principle, and the first principle of Western civilization, is that there is and can be only one reality. If there can be multiple realities, we lose both Jerusalem and Athens. If there can be more than one reality, there can be more than one God; so falls Jerusalem and monotheism. If there can be more than one reality, what is logical in one means nothing in others, where logic itself may not hold; so falls Athens and reason. All things are indeed relative where realities proliferate.

Hell has always hated reality, for in the real world, Christ is King. Old Screwtape’s problem, for millennia, was that philosophy made a poor weapon against reality. Even Hell’s most sophisticated philosophical device, ideology, fell sure prey to reality, seldom lasting more than a couple of generations. His Wormship knew that he needed a more powerful and enduring weapon than philosophy could provide. He needed convincing but false images of the true: virtual realities.

Virtual realities existed, to be sure. Nero’s Domus Aurea was one; Marie Antoinette’s life as a shepherdess another. Military headquarters were often wonderful generators of virtual reality. (We now flood ours with computers, making the problem worse.) But these took great power and vast resources to create and were also impossible to sustain.

If Hell were to triumph over reality and make it stick—which comes very close to triumphing over God—it needed to find a mechanism that could create powerful, compelling virtual realities, proliferate them widely, and enable people to live in them, self-convincingly, most of the time. And then, brilliantly, Hell’s workshops begat the cathode ray tube and the video screen.
