Oh, no, not at all! I'm quite happy to have people interested in what I have to say, but I'm trying to keep my conversation suitable for the 'Welcome to Less Wrong' thread, and not have it get too big. ^_^
As far as 'If it's logically fallacious, why is it the foundation of your belief?'
Well, it's not the foundation of my belief, it's just a very strong element thereof. It would probably require several months of dedicated effort and perhaps 30,000 words to really hit the whole of my belief with any sort of holistic effort. However, why assume a First Cause? Well, because of entropy, we have to assume some sort of start for this iteration. Anything past that starts getting into extreme hypotheticals that only really 'make more sense than God' if it suits your pre-existing conditions. And no, I'm not saying God makes more sense outside of a bias - more that given a clean slate, "There might be laws of physics we can't detect because they don't function in a universe where they've already countered entropy to a new start state" is about equal to "Maybe there's a Deity figure that decided it wanted to start the universe" are about equal in my mind. And to be fair, 'deity figure' could be equivalent to 'Higher-level universe's programmer making a computer game.' Or this could all be a simulation, and none of it's actually real, or, or, or...
But the reason that I decide to accept this as a basic assumption is that, eventually, you have to assume that there is truth, and work off of the existing scientific knowledge instead of waiting for brand new world-shattering discoveries in the field of metaphysics. So I keep an interested eye on stuff like brane vibration or cosmic froth, but still assume that entropy happens, and the universe had an actual start.
if Thor came down throwing lightning bolts and etc, and claiming our worship, I'd be... well, admittedly, a little confused, and unsure. That's not exactly his MO from classic Norse mythology (which I love) and Norse mythology really didn't have the oomph of world creation that goes together with scientific evidence. I'd have to wonder if he wasn't a Nephilim or alien playing tricks. (Hi, Stargate SG-1!)
However, I take your meaning. If some deity figure came down and said, "hey, here's proof," yeah, I'd have a LOT of re-evaluating to do. It'd depend a lot on circumstances, and what sort of evidence of the past, rather than just pure displays of power, the deity figure could present. What answers does it have to the tough questions? Does it match certain anti-christ elements from Revelations?
Alternatively, what sort of evidence would make me change my mind and become atheist?
I would love to be able to easily say, "Yeah, if this happened, I'd totally change my mind in an instant!" but I am aware that I'm only human, and certain beliefs have momentum in my mind. Negative circumstance certainly won't do it - I've long ago resolved the "Why does a good God allow bad things to happen?" element. Idiotic Christian fanboys won't do it - I've been developing a very careful attitude towards religion and politics in divorcing ideas from the proponents of ideas. And if I had an idea what that proof would be - I'd already be researching it. So I just keep kicking around looking for new stuff to research.
Thank you for the interest!
Sounds like you've given this some serious thought and avoided all kinds of failure modes. While I disagree with you and think that there's probably an interesting discussion here, I agree that this probably isn't the place to get into it. Welcome to Less Wrong, and I hope you stick around.
If you've recently joined the Less Wrong community, please leave a comment here and introduce yourself. We'd love to know who you are, what you're doing, or how you found us. Tell us how you came to identify as a rationalist, or describe what it is you value and work to achieve.
If you'd like to meet other LWers in real life, there's a meetup thread and a Facebook group. If you've your own blog or other online presence, please feel free to link it. If you're confused about any of the terms used on this site, you might want to pay a visit to the LW Wiki, or simply ask a question in this thread. Some of us have been having this conversation for a few years now, and we've developed a fairly specialized way of talking about some things. Don't worry -- you'll pick it up pretty quickly.
You may have noticed that all the posts and all the comments on this site have buttons to vote them up or down, and all the users have "karma" scores which come from the sum of all their comments and posts. Try not to take this too personally. Voting is used mainly to get the most useful comments up to the top of the page where people can see them. It may be difficult to contribute substantially to ongoing conversations when you've just gotten here, and you may even see some of your comments get voted down. Don't be discouraged by this; it happened to many of us. If you've any questions about karma or voting, please feel free to ask here.
If you've come to Less Wrong to teach us about a particular topic, this thread would be a great place to start the conversation, especially until you've worked up enough karma for a top level post. By posting here, and checking the responses, you'll probably get a good read on what, if anything, has already been said here on that topic, what's widely understood and what you might still need to take some time explaining.
A note for theists: you will find LW overtly atheist. We are happy to have you participating but please be aware that other commenters are likely to treat religion as an open-and-shut case. This isn't groupthink; we really, truly have given full consideration to theistic claims and found them to be false. If you'd like to know how we came to this conclusion you may find these related posts a good starting point.
A couple technical notes: when leaving comments, you may notice a 'help' link below and to the right of the text box. This will explain how to italicize, linkify, or quote bits of text. You'll also want to check your inbox, where you can always see whether people have left responses to your comments.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site.
(Note from MBlume: though my name is at the top of this page, the wording in various parts of the welcome message owes a debt to other LWers who've helped me considerably in working the kinks out)
