"Spiritual" to me means "concerning the deepest values by which I lead my life." (I stole that phrase from wikipedia yes, but it describes my feelings pretty accurately.) The meaning of life.
It's nothing supernatural, it's just moments of coming face to face with one's own nature, and one's interrelatedness with the world.
Stop dichotomising science and art
Can we have this on a tee-shirt please Paul?
Quantifying a soul or a spirit seems to be a similar (or the same) concept as quantifying consciousness: the concept itself is so fragmentary and vague that there's no clear way to research it.But as you say, that could change one day. Something being beyond the possibilities of scientific analysis at the moment, or maybe even ever, doesn't mean it's inherently nonscientific.
with enough information (heredity, chemical make up, diet, psychological history, environment, societal influence, etc), every action and outcome should be predictable.
