I'm not sure if this is breaking the new guidelines or not, though...

Yes, actually. The scientific method cannot be used in this case; and would be foolhardy to use, since even if the soul existed, because it is immaterial, empiricism would be blind to its existence. The scientific method can neither confirm nor deny the existence of a soul; therefore, some other standard must be used.
This mechanism is logic. The logical argument for a soul is founded upon the Law of Identity, which states that if A and B are equal, then all that is true of A is necessarily true of B; and that all properties of A are the same as all properties of B.
If the soul does not exist, and we are our bodies and nothing more, then this ought to be confirmed by the Law of Identity.
There are a few arguments that show that this is not the case.
1) The body is dubitable, but the self is not.
For instance, it is possible that my body does not exist (see: The Matrix). However, by the very fact that I doubt the existence of my body, someone is doubting; and that person IS. "To doubt is to exist."
2) The body changes, the self does not
Those of you immersed in the realm of science know that every 9 years or so, the body is completely remade; not only the cells, but the molecules and atoms as well.
However, if I were to say, "I've changed a lot in the past 2 decades," that statement, in and of itself, inherently assumes a dualism of body and soul. The "change" happened to the same person, though his body completely physically changed. Something stayed the same - it is not the physical; therefore, it must be immaterial.
Those are just a couple of arguments. I can't claim that I made them up; rather, I got the premise (and the core of the arguments) from a friend. I think they serve reasonably well, though. Yes, they're underdeveloped in here, but I didn't have much time. Sorry. =)
