The Biblical concept of a human being was of an animated body, returning to dust at death.
The Platonic concept was of a reincarnating soul that achieved perfection only in disembodied pure thought.
The Aristotelian concept was that the soul was the form of the body.
Christianity synthesized the Biblical and Platonic concepts. Christians expect a hereafter for the soul immediately after death but also await the resurrection of the body.
If a soul is:
(a) to have new sensory experiences and
(b) to communicate with other conscious beings -
- between the death and resurrection of its body, then it needs at least the appearance of a body inhabiting a shared environment. So is Dante's and Niven & Pournelle's Inferno a mere appearance?
Poul Anderson provides a physical Hell by having inert matter animated by parapsychic forces. See here.
Addendum, 14 Mar '16: CS Lewis suggests in Letters To Malcolm that a realistic appearance of the body is the resurrection of the body. However, I do not share Lewis' Platonic mind-body dualism. I think that being became conscious. Reality is one.
