the original was that "everything in the material world moves"Hi LG,
Made simpler, the argument is:
1) Everything that moves must have a moving mover
god introduces the concept of duality - namely that he is unique because he is the foundation of the material world (as opposed to his foundation being in the material world)2) There can't be an infinite chain of movers
3) Therefore there must be something that moved without a mover
But 3) contradicts 1). So which one is false? Note that the argument is not a syllogism, by the way.
hence there is no problem between 1 and 3
hmmmmA more logical argument would be:
Movement exists.
If it is assumed that there is no infinite chain of movers or causes, then...
There must have been at least one case in which movement occured without a mover.
Now, assuming the truth of the assumption (no infinite chain), the argument does not show that there was only one prime mover, nor does it attach any other attributes to that prime mover, unless you make other unspecified assumptions (eg "material laws prohibit unmoved movers", or "Only God can be a prime mover")
I will get back to this a bit later perhaps
but just off the top of my head, if one advocates the possibility of there being several prime movers, they must be unified in some fashion, since the definition doesn't allow for one prime mover (A) to move another (B) and still enable (B) to be classified as a prime mover
