6. The physical causes of everything we think of as the soul.
This is confusing hardware with software. If you damage a computer, the software won't run- but that doesn't deny the separate existence of the software. The mind, and presumably the soul, are dependent upon the brain for existence, yes- but then, I think the Divine may have a physical presence, too, as I speculated here . Please keep in mind, however, that it is only idle speculation to explain observed phenomenon, not a doctrine.
7. The complete failure of any sort of supernatural phenomenon to stand up to rigorous testing.
Scientific testing assumes a consistency of result you don't always find when dealing with autonomous sentient beings. For example, if tested under laboratory conditions, one might conclude that my cat doesn't know his name because saying "Here, Garfunkle" has erratic results in producing said cat. Calling "Here, Goddy Goddy Goddy" is unlikely to be any more reliable. But that doesn't mean that neither one has ever responded when addressed.
8. The slipperiness of religious and spiritual beliefs.
"If things go the believer's way, it's a sign of God's grace and intervention; if they don't, then, well, God moves in mysterious ways, and maybe he has a lesson to teach that we don't understand, and it's not up to us to question his will. That sort of thing. No matter what happens, it can be twisted around to prove that the belief is right."
As with "The increasing diminishment of God.", this is a problem with certain specific religions, not all religion as a whole. Those of us who believe that the Divine does not punish by causing natural disasters, nor rewards by salvation from natural disasters, don't have this problem.
9. The failure of religion to improve or clarify over time.
There's a lot of things in this category, not just religion. We have no better understanding of love or life or even how to live together without oppression and war than we did 35,000 years ago. Like all of these things, the Divine is something experienced personally, new and different for each person. Centuries of trying in this arena is meaningless, because your experience- the only one that counts for you- is only decades old. All of Man's literature on love doesn't tell me how to live with a broken heart, and neither the Bible nor the Bhagavad Gita told me how to deal with my own religious experiences.
10. The complete and utter lack of solid evidence for God's existence.
Greta, I'll agree with you completely if you rephrase it: You have no solid evidence for God's existence. In fact, I'll even say you'd be a fool to believe in a flying spaghetti monster if you've never seen one. I'll also agree that it's not up to you to prove that God doesn't exist. I agree that it's an extraordinary claim. But I'm not trying to convince you. I know I cannot convince you; my evidence is non-transferable. Moreover, I don't care what you believe; I do not proselytize. Since I don't believe in the inherent depravity of man, or Hell, I don't even have the altruistic motive of trying to "save" you.
So what do I want?
I want atheists to stop saying "there is no evidence", when what they mean is "I haven't seen any evidence". First of all, it's not logical to say that because you haven't seen it, it doesn't exist; the absence of evidence is not evidence of absence. (I'm not speaking here of the existence of Divine itself, but of the existence of the evidence- the personal experience) This is why some theists get angry at the more activist of the atheists- if the theist has explained that his or her belief is based on actual experience, than repeating "There is no evidence" is a personal insult, an accusation that the theist is either lying or insane. A corollary to this is saying things like "Faith is believing what you know ain't so", as some of us know it is so. Why do atheists find it so hard to understand that calling someone a liar, a crook, or a kook makes them angry? I fully acknowledge that my proof is non-transferable and unconvincing to anyone else; why can't atheists acknowledge that there are those who have experienced the Divine and yet, by actual medical evidence, are not schizophrenic, nor have any neurological pathologies, and are not of subnormal intelligence?
I want atheists to be more specific. If you have a problem with fundamental Christians, say so; stop using the term "religion" if you mean Christianity. Funny how some of the atheists who are the most insistent on precise definitions of the words "atheist", "agnostic". etc., are the biggest offenders in painting all faiths with a broad Abrahamic brush.
These two concessions alone- and surely they are not too much to ask for- would take most of the heat out of the discussion. And by doing so, atheists might be surprised at how many allies they'd find among even the strongest of theists on issues such as Evolution, keeping religion out of schools, etc., just as I have been surprised sometimes by Christians supporting me, a Pagan, when attacked in forums by aggressive atheists.
