Science is limited to things that exist.
There is even the science of religion I believe.
There is metaphysics but they draw upon science and philosophy.
History can be seem as both science and humanities.
Psychology is both Philosophy and science.
It is hard to think of nothing, if not impossible.
My problem with dualism is that the separation of science and religion creates a larger divide. I prefer a naturalism or organic view of the universe. Religion seems to be a way of life as opposed to knowledge.
It is ever changing like language. Science is more ordered and in theory self correcting while religion/spirituality is a practice within a community.
Except for some mystics which maybe more of a love affair.
When people devote there lives to a book such as the bible it often becomes the object I think this would be what Whitehead would call Misplaced concrescence. The real would be the feelings and thoughts behind the writings in their context. They tend to take on meanings not intended but yet every bit as related to the believers perceptions and meaning. I don't remember my point. But I think we are agreeing.

Thanks for the thread QED it looks interesting. I will read it after I take a nap.
