On the first note, thanks for pointing these things out. You find any 
more flaws? 

And on with the clarification.

The problem with the "virtual energy field" hypothesis of summoning is 

that it would lead to the conclusion that summoning spells should be 
absolutely safe; any attempt of the summoned creature to leave the 
energy field is thwarted by the fact that the rules of manaphysics does 
not allow such a thing to happen. This means that all stories of chaos 
caused by demons breaking out of their summoning circles are bullshit. 
All such summonings are essentially temporary bridges between worlds 
surrounded by a ward that prevents escape.<<

The idea is that the energy field could be nulled by that which is 
summoned (if they're strong enough). This was the intended loophole.

Note: The "bridge" doesn't exist. That which is summoned only appears at 
the given quantum location due to a change in "energy levels" (like 
electrons).

The notion of "sacrificing part of one's soul" sounds a bit unnerving 

to me. What if you can't get to the apple to recover your little bit of 
soul? What happens when this occurs once too often?<<

These are the little grey bits that makes this theory 'not rigorously 
defined.'

Also, what about creatures that supposedly have no soul, yet can work 

magic anyway, such as vampires? Do these guys [a] actually have a soul, 
[b] can't work magic, or [c] don't exist in the first place? A 
hypothesis of magic that allows soulless creatures to work magic cannot 
use soul-power to fuel it.<<

If I remember correctly, what I said was alongthe lines of, "If 
something is material, then it has a soul."

Note: This definition of soul is working on a variant of the theory of 
relativity. The difference is that The gravitational pull attributed to 
matter is actually separate from matter. In this theory, the 
gravitational field is the "soul." The above conditional thus works.

This means that souless monsters

a) Actually have souls.
c) Can't exist.

There's no reason why these two can't happen at the same time.
Any entity in existence can work magic (years and years of training. 
Who'd bother, though?).
