'Does the soul exist?' is the same kind of question as 'does information exist?'.
At first we thought information was immaterial, quite like the soul. But now we know information is part of the movement to greater entropy and so is material. And so we suspect the soul is material as well.
I was watching a film where a man was discussing the problem of free will in relation to science, and apparently much like the idea of God knowing our fate but us having free will, our lives are mostly governed by natural laws which are unavoidable, but we still have unique personalities.
I've noticed a lot in my studies that scientists are just starting to "prove" things that certain groups of religious people already knew for centuries.
This is particular impressive in the field of medicine, where even in Western medicine, doctors are going to have to back-track from a purely Western approach, because they're acknowledging the validity more and more of preventative medicine in things like massage and eating the correct foods, which is an ancient idea in the East, as well moving back toward more natural birthing practices for women (with some medical supervision) and the power of emotions and faith and meditation and belief upon the physical health.
In the future, people will recognize the validity of East and West working together, and of science being the what and religion being the why. I sincerely believe this.
Because when everything attempts to become too Westernized something is missing, women were having unnecessary C-sections, doctors weren't acknowledging the validity of natural medicine and the power of the mind at all, and so forth. It's only as we've come more into the 21st century that things are becoming more balanced.
Eastern and Western thought are both necessary for the optimal state of humanity. Focusing too much on Western thought becomes ridiculously literal and black/white, right/wrong, divisive, and what many Easterners refer to as a wild imbalance of too much masculine energy.
