Long time lurker, but I've barely posted anything. I'd like to ask Less Wrong for help.
Reading various articles by the Rationalist Community over the years, here, on Slate Star Codex and a few other websites, I have found that nearly all of it makes sense. Wonderful sense, in fact, the kind of sense you only really find when the author is actually thinking through the implications of what they're saying, and it's been a breath of fresh air. I generally agree, and when I don't it's clear why we're differing, typically due to a dispute in priors.
Except in theism/atheism.
In my experience, when atheists make their case, they assume a universe without miracles, i.e. a universe that looks like one would expect if there was no God. Given this assumption, atheism is obviously the rational and correct stance to take. And generally, Christian apologists make the same assumption! They assert miracles in the Bible, but do not point to any accounts of contemporary supernatural activity. And given such assumptions, the only way one can make a case for Christianity is with logical fallacies, which is exactly what most apologists do. The thing is though, there are plenty of contemporary miracle accounts.
Near death experiences. Answers to prayer that seem to violate the laws of physics. I'm comfortable with dismissing Christian claims that an event was "more than coincidence", because given how many people are praying and looking for God's hand in events, and the fact that an unanswered prayer will generally be forgotten while a seemingly-answered one will be remembered, one would expect to see "more than coincidence" in any universe with believers, whether or not there was a God. But there are a LOT of people out there claiming to have seen events that one would expect to never occur in a naturalistic universe. I even recall reading an atheist's account of his deconversion (I believe it was Luke Muehlhauser; apologies if I'm misremembering) in which he states that as a Christian, he witnessed healings he could not explain. Now, one could say that these accounts are the result of people lying, but I expect people to be rather more honest than that, and Luke is hardly going to make up evidence for the Christian God in an article promoting unbelief! One could say that "miracles" are misunderstood natural events, but there are plenty of accounts that seem pretty unlikely without Divine intervention-I've even read claims by Christians that they had seen people raised from the dead by prayer. And so I'd like to know how atheists respond to the evidence of miracles.
This isn't just idle curiosity. I am currently a Christian (or maybe an agnostic terrified of ending up on the wrong side of Pascal's Wager), and when you actually take religion seriously, it can be a HUGE drain on quality of life. I find myself being frightened of hell, feeling guilty when I do things that don't hurt anyone but are still considered sins, and feeling guilty when I try to plan out my life, wondering if I should just put my plans in God's hands. To make matters worse, I grew up in a dysfunctional, very Christian family, and my emotions seem to be convinced that being a true Christian means acting like my parents (who were terrible role models; emulating them means losing at life).
I'm aware of plenty of arguments for non-belief: Occam's Razor giving atheism as one's starting prior in the absence of strong evidence for God, the existence of many contradictory religions proving that humanity tends to generate false gods, claims in Genesis that are simply false (Man created from mud, woman from a rib, etc. have been conclusively debunked by science), commands given by God that seem horrifyingly immoral, no known reason why Christ's death would be needed for human redemption (many apologists try to explain this, but their reasoning never makes sense), no known reason why if belief in Jesus is so important why God wouldn't make himself blatantly obvious, hell seeming like an infinite injustice, the Bible claiming that any prayer prayed in faith will be answered contrasted with the real world where this isn't the case, a study I read about in which praying for the sick didn't improve results at all (and the group that was told they were being prayed for actually had worse results!), etc. All of this, plus the fact that it seems that nearly everyone who's put real effort into their epistemology doesn't believe and moreover is very confident in their nonbelief (I am reminded of Eliezer's comment that he would be less worried about a machine that destroys the universe if the Christian God exists than one that has a one in a trillion chance of destroying us) makes me wonder if there really isn't a God, and in so realizing this, I can put down burdens that have been hurting for nearly my entire life. But the argument from miracles keeps me in faith, keeps me frightened. If there is a good argument against miracles, learning it could be life changing.
Thank you very much. I do not have words to describe how much this means to me.
Hmmm. The fear of hell is a tough one: as I said above, I'd largely dealt with that fear before "leaving the fold." I suppose you somehow need to train your System 1 - to reprogram yourself, to experience that you have nothing to fear. For me, this happened over time as I gradually got more comfortable with increasing degrees of irreligion. Some other suggestions follow.
Hell and other people
For instance, it may help to think about the many non-Christians of superlative moral character. I mean, even the medieval Christians called Socrates a "Christian before Christ" - in other words, they thought so highly of Socrates that they could not really imagine him going to hell. Similarly, the more you think of really excellent, though still flawed, humans, it may become more difficult to picture a just and fair outcome where they suffer forever. It just doesn't make moral sense. And really feeling that moral impossibility as applied to non-Christians might help give you confidence that all non-Christians do not go straight to hell. (of course, much Christian teaching aims to establish precisely such a gap between apparent and "actual" moral deserts)
Fears and Experience
If you have multiple fears, perhaps you could enumerate each of them to yourself. Churches tend to bundle together charity, social events, counseling, and parenting and marriage advice, and so a "relationship with God" is supposed to ensure all of that, and deconversion may seem to threaten all of that. For me, becoming friends with more and more perfectly well-adjusted and strong individuals who had always been secular helped disprove the notion that a good life falls apart without religious belief.
Or, to give another example, some Baptists teach that alcohol is a sure road to ruin (really) - only experience gets rid of this fear. Take a drink, feel that you're fine in the short- and long-term, and you feel better about rejecting that moral teaching.
Conscience is the voice of the community
In the Christian world, what you believe determines who you go to church with, and thus with whom you're friends. Scott Alexander talks about Red and Blue tribes, pointing out that secular political beliefs also determine who you're friends with. (I find this idea similar to Robin Hanson's "beliefs as clothing" idea - change your ideas, change your uniform, change sides) So this isn't a religious phenomenon only, but it was just more obvious growing up. As a result, the social aspects of religious belief change can be even more obvious and pressing than other sorts of belief change. That's all a roundabout way of saying fear of hell may be related to fear of coming out to friends and family, and thinking about how to handle the latter if you were to deconvert may help your fear fear of hell.
Finally, I forget which writer commented that Enlightenment Europe didn't think religion could become a non-issue; it seemed it was one of the "eternal questions." But in fact Europe's over that now, and despite the social prevalence of religion in the States, in any professional circles I've ever been in, religion simply can't be mentioned. For us individuals also, religion can simply fade into our rearview mirror. Except for this comment, I don't think about or miss Christianity anymore. I don't experience tension that "it might be true," as some undecidable and imposing question. It's a rather boring topic. Now I spend my mental energy not on reconciling abstruse and dusty doctrines, but on learning actually useful things (there is so much knowledge left to create!). You only need to deconvert once.
Which fears can you deal with by living through others, and which through direct experience? That might be a path forward. Good luck!
Actually, I don't have any of the community-based fears. Most of my friends are atheist or irreligious, and while my family would be concerned, I'm not especially worried about their reactions. The guide for the recently deconverted is nice, but I'm still having fears. Sorry-I'm not trying to drag things out! But this is taking a while, and I wish there was a way to just stop worrying.
