I have a few problems wih the spell "exchange of two minds" (arm5 pg 152).
The spell description states that the spell switches the minds (but not the souls) of two creatures. The spells duration is a year.
Problem 1.
Why is the spells duration 1 year rather than momentary? Suppose two people each have a rock in their mouth. If we wanted to exchange these two stones we would use a momentary rego terram spell (perhaps with a corpus req?). It seems weird to suggest that the exchange of two stones (or other material objects such as hearts, blood, etc) would be anything but momentary (that is permanent, until otherwise affected). Now I think within the context of ARM it is safe to say that the mind is a non-material object, something akin to Decartes notion. So why can't a rego spell move two non-material objects with a momentary duration, in the same way one would move two material objects (e.g. stones)?
When we turn to arm4 we find that the exchange spell (pg 112) had the capacity to be permanent. So unless there was a change in metaphysics from arm4 and arm5, it seems that we could have two minds switch indefinitely: so long as we create the effect within the mechanics of arm5 rules.
Problem 2.
One of my players wants to be able to indefinitely exchange minds (as in ARM4). Is this possible? Can this be done via a hermetic breakthrough. If so,what would that process look like: e.g. a new duration, or is it a breaking of a hermetic limitation,etc.?
Problem 3.
In true lineages pg 112, when discussing Guorna it states:
"she designed a ritual that would move her spirit to a younger body..."
Is this meant to be the same spell as exchange of 2 minds? If so why did they not say mind rather than spirit? Is there a difference between a mind and a spirit or are they the same? What is the difference between a spirit and a soul?
Problem 4
Whats the difference between a soul and a mind?
As the spell indicates, there is a difference between the two. My commonsense view is that the mind is our conciousness plus our cognitive and emotive mental features. Thus, when the spell is cast the characters mind (consciousness plus cognitive/emotive features) now inhabit the new body. If that is correct, and the soul does not transfer, then what has not transferred? Also, why should I think that whatever has not transferred is some part of me? What I mean to say is, when I think about who I am, I think of my mind. Anything that would remain is just not essential to who I am.
When I attempt to think about what a soul is I am clueless. Now we might want to say the soul just is our mind. But that is not an option in ArM5 core rules (as I understand them).
Problem 5
Ok, real trouble now. When I read A&A confusion occurs.
pg 31
"The mind as nourished by the sensitive faculty, is the link between the body and the soul."
This supports the distinction between mind and soul. But then we read...
pg31
"The principle difference between the mind of an animal and that of a human is the possession of a soul, which is unique to rational beings such as humans, angels and demons. The soul PROVIDES both reason and intellect."
Does that mean that reason and intellect are part of the soul and not part of the mind? If so then the result of the spell in quesion would be a magus incapable of reason, that doesnt seem correct. Also, I am unclear, do fairies have a soul (I seem to recall reading somewhere that they do not)? This is important because even though they may be whimsical they cerainly can reason and have intellect: fairies can add, solve problems, make judgements, etc. If that is so, then we have a case were a soulless being has intellect and reason.
pg 32
"Hermetic magic cannot affect the functions of the soul - REASON and INTELLECT -even though they form part of the thinking mind."
I always thought that reason and intellect where functions of the mind, not the soul (whatever that is). This passage totally confuses me about the relationship between mind and soul. I just dont get what the author intends here. It seems open to a wide range of interpretations.
Problem 6
Suppose God removes the soul from a living magus: what happens? Does he die? Or, is he a mental vegetable? If he can still think and reason then I have no idea what he has lost? Whatever he lost, if he still has a functioning mind, then it seems he has lost nothing really important.
P.S.
I am not attempting to reject the medieval paradigm. I am just trying to make sense of it as presented in the source books.
I appreciate any help here.
Thanks
