I don't give religion a "free pass"... is simply realize that it has a specific limited role in my life. That is, it informs how I personally relate to nature and my place in the universe and in cultural/moral decision making.
That is, of course, your choice, however you say it "informs" you, which means that it must involve some kind of "information" to the table. How do you judge the validity of that information?
I can not empirically decide how a rainbow makes me feel... I can understand how it forms, how it demonstrates physical realities about the way the world works... but I can't decide that it evokes wonder or measure it. Nor can I decide empirically if it will cheer me up or not.
Not yet, but neuropsychology is still in its infancy. We are getting closer all the time to figuring out how the brain, and therefore the mind, actually works. While we cannot empirically show how and why certain things make us feel certain ways it is not something that I consider to be theoretically impossible, merely hindered by our current lack of understanding.
My faith doesn't tell me why a rainbow exists except to illustrate cultural value lessons... It gives me an insight into what my ancestors thought and placed value on. How should I empirically measure this? Should I only enjoy a story or a song that has scientific merit?
I personally think that people should do whatever they enjoy so long as it doesn't hurt anyone else.
But as I mentioned, while it may not be possible to empirically measure that experience yet, I do not see it as impossible at some point in the future.
I think Spinoza comes very close to my theism.
I think Spinoza comes very close to Deism, not Theism.
If you can suggest a way to empirically measure the value of culture then by all means do share.
Not completely and fully, but one can to some degree empirically measure the value of a culture. One can measure its success, its staying power, the happiness of its inhabitants, how well it cares for the weak in its midst, what progresses it contributes to the world as a whole, how well it upholds certain values that we think is important (highly subjective, but measurable) and so on and so forth.
