Of course we are more than sum total of our parts, that's not in doubt. Yet it is the interaction of the sum total of parts that enables function, life, the world and everything in it, the Universe.
The question here is the status of will....we know that have will, but what does it do? What is its function? How does it form? Answering these questions is a matter of research and testing, not philosophy, ideology, religion or faith.
