For an interesting, if dense, scientific consideration of soul, consciousness, and Platonic truth, read "Morality at the Planck Scale," a chat with Stuart Hameroff. Reading this Metanexus posting, I recalled that Hameroff is the anesthesiologist whose work Roger Penrose cites in his equally dense (and much longer, being a book) "Shadows of the Mind." The basic notion of these brilliant guys is that teeny-tiny microtubules in the brain's nerve cells are small enough to involve quantum effects at the teeniest-tiniest level of physical reality, which is the Planck scale.
This means that there is a connection between us, our brain, and the cosmos, the undivided whole of the quantum world. The great mystery to consciousness researchers is how something physical, the brain, seems to produce something nonphysical, consciousness. But Hameroff says that he calls himself a panprotopsychist (yeah! I'd join that church), which entails "the notion that whatever gives rise to consciousness is implicit and exists inherently everywhere in the universe." Including the quantum realm, which connects with our consciousness, or soul if you like, through those microtubules. Hameroff suggests that "the soul could be a particular distributed pattern in fundamental spacetime geometry at the Planck scale." Well, maybe the Church of Panprotopsychism isn't going to attract many members, if this is the Creed: "We believe in soul, a particular distributed..." The Lord's Prayer has more of a ring to it.
