I think we need to define consciousness or soul or whatever first. In the sense of the mind, even, what is a mind? There is something that does have to have some connection to our physical actions, but how we conceptualize that thing is more open-ended. "Physical" is more accurately, if crudely put, "forces and objects we can obviously observe", but science is the very question of what we observe, so we're treading on very uncharted territory with this topic. Maybe we will one day gain access to a very different world that will seem as obvious as being able to pick up a chair.
