Lets change your question -- ever so slightly, given the Turing-context: 

In what way does the Turing Test depend on the existence (or non-existence) of the soul?

When you say "soul" you (seem to?) mean what has been called with justifiable
derision, "dualistic notion of soul"
- something for which Christianity gets bad press though its the invention of Descartes
http://www.iep.utm.edu/descmind/
- something which caught on because of Descartes huge reputation as a scientist

There are other more reasonable non-religious non-dualistic notions of soul possible:

<snipped stuff on numbers>
You are missing the point -- its not about specific numbers its about 
cardinality not adding up

- Cantor theory points to uncountably many real numbers
- All the sets upto algebraic are countable
- So the uncountable fellas need to be transcendental
- We only know two blessed guys -- ? and e

Where are all the others hiding??

And dont try saying that if e is transcendental so is 2e 3e 4e...
And no use trying more such tricks -- they only multiply these two countably infinite times
And you may produce a few more, more esoteric transcendentals --- a very
finite set!

Nor is it much good saying this is not much relevance to our field:
https://en.wikipedia.org/wiki/Cantor%27s_diagonal_argument

So our (computer scientists') predicament in short

- our field is opposed to Cantor's non-constructivist *outlook*
- At the foundation of CS are *methods* that.... come from Cantor... OOPS!
