Resurrected Reality

In several works by Poul Anderson, human beings enter AI-generated virtual realities that are indistinguishable from external physical reality. In Anderson's speculative novel, Genesis, these virtual realities include "emulations" in which the AI generates subsidiary consciousnesses who think that they inhabit, e.g., eighteenth century England.

Some mentally powerful fictional characters are able to generate shared virtual realities without computer assistance, e.g., in Adrian Breze's "memory palace," Ellen Breze, commenting that the experience is real for them both, taps the tile floor, feels heat from the fire and mountain air in her lungs and smells burning conifer wood.

"You couldn't tell this from reality..."
-SM Stirling, The Council Of Shadows (New York, 2012), CHAPTER TWO, p. 36.

This prompts yet another comparison of Anderson and Stirling with CS Lewis because, in Letters To Malcolm (London, 1966), Chapter XXII, (see here) Lewis conceptualizes the hereafter as an immaterial shared virtual reality. He argues:

the idea of the soul reassuming the corpse is absurd;
it is not what St. Paul's words imply;
the corpse could have been utterly destroyed or dissipated;
matter is important only as the source of sensations;
waves and atoms are unimportant;
memories of past sensations might prefigure a power to resurrect those sensations permanently and no longer privately;
Lewis might take Malcolm for a walk through the vanished fields of his childhood which now are building-estates.

Comments
(i) Far too "idealistic," in the philosophical sense. (But then Lewis was a Platonist.)
(ii) St. Paul differentiated the spiritual body from the physical body but the Gospels show us a reanimated corpse.
(iii) Waves and atoms are not unimportant but are the matter/being/energy that becomes conscious of itself in and through psychophysical organisms.
(iv) To dismiss the discoveries of empirical science as unimportant is obscurantist.

"Matter enters our experience only by becoming sensation (when we perceive it) or conception (when we understand it). That is by becoming soul." (p. 123)

An assumption of the existence of immaterial souls. I suggest that matter/being/energy, organized as psychophysical organisms, experiences, perceives and understands itself.
