OK, I'm finally taking the time to respond to the last round of posts. Sorry for the delay. Also, this week continues to be extremely busy, so further responses may be just as sporadic.
@dave bishop,
Thank you for your post. You make an interesting point, but not a succesful one. I'm going to address your second, subsidiary point first, though. You say,
"Atheism is not irrational. The belief that the laws of nature will continue to be the same in the future may be irrational, but that does make a non-belief in God irrational. It is not a shambles of a worldview to admit there are some things we can’t know rationally, or to admit all knowledge is subject to some doubt. It is a shambles to invent an entity to solve your epistemic problems and then trick yourself in believing that rationalises all your other world beliefs. "
Atheism is indeed irrational if it cannot support reason or the ability to know. In such a world view, there is not even such a thing as reason in the sense we mean reason. Let me try to put it another way. You grant above that (assuming your world view) belief in regularity of nature is irrational. But that means every atheist is committed to a belief that is not rational in his own world view, and to living his life by it. I would consider this an irrational worldview.
Now, on to your main points.
Every world view, Dave, requires some assumptions. I've said this again and again, and nobody's disagreed, so I suppose it is not controversial. So I am not attacking atheists for having some assumptions. However, the assumptions should not be completely arbitrary, and outside the supposed system of knowledge in the world view. The atheistic world view is deficient because _on its own terms_, there is no believe in any source of actual knowledge. This is not true about the Christian world view. Let me elaborate.
Let's talk about belief in regularity, or induction, again (I could choose other things, of course, but we started there, so let's stay there for now). Awhile ago I made a big deal of pointing out that induction cannot be supported by a logical argument that is not circular. (David Hume originated this argument, of course). Still, that might be OK. Maybe we know it for some extra-logical reason. So perhaps we might say, OK, let's just assume it.
Now here's the question: is it a general belief of the atheist that whatever we assume is true? No, it is not. Of course not. Nobody thinks that. So assuming it does not support its truth _in your world view_. Well, OK. We're born with a belief in regularity. Is it a belief that whatever humans are born believing is true? No, that's not true either. Actually, you have beliefs about how humans gained their innate knowledge (evolution, etc.) which would instead _undercut_ any belief that such knowledge was correlated with the actual behavior of the future.
OK, so, it turns out there just is no adequate source of this knowledge at all, in your world view. It has to be an assumption, but it's going to have to be an arbitrary assumption by your own standards. It will be a belief that does not comport with your own beliefs about why things should be believed.
Or, to put it another way: suppose you do just assume induction. That then enables you to "know" many things. But it still doesn't enable you to know how you came to know that induction was true. Even taking it as a bare assumption, you can't deduce anything that would enable you to know it was true.
Now, let's compare Christianity. As Dexter pointed out earlier, there's a certain circularity here, as well, as there will be for basic beliefs -- but it does NOT suffer from the deficiencies pointed out above. For example, you've brought up the issue of whether God changes (in sufficiently radical ways that His promises of near-order would be broken). Well, what do I believe as a Christian? I believe that God is all-knowing and tells His followers the truth in His Word. So, given that He says He won't change like that, I can believe that He won't.
"But wait, semck," (you'll say) "why do you believe that He is all-knowing and tells the truth in the Bible? Isn't it because the Bible says so? Do you expect me to believe such ludicrous circular logic?"
No, I don't, because you're not a believer, but we're critiquing the consistency of _my_ beliefs. So let's do that. So again, we see there is circularity here, as before, so there is going to have to be some other source of the information. Well suppose we just assume it, as before -- the Bible is the true Word of God. Do we run into the same problem as the atheist did for induction? Ah! We do not. Unlike your bare assumption of induction, which provides no further knowledge to make it anything more than a bare assumption, my assumption of the Bible is no longer a bare assumption in the worldview that that assumption entails. It explains how I would know such a thing: an all-knowing, truthful God told me so. Hence, _inside the Christian worldview_, all the knowledge that I claim can be accounted for. I don't have any beliefs that contradict my own beliefs about what can be believed or known.
So, although I criticized induction for being circular to illustrate that it did not follow from reason and show that it was an assumption, in a real sense it is precisely because your worldview _fails_ to be circular (in a different sense) that it falls apart. You can assume all you want, but none of your assumptions explains why your assumptions could have any validity.
So what about all the points you raise -- the lying God, the changing God, etc., etc.? Well, those just aren't my world view. Those are other flawed world views that also would not support knowledge; but I have a perfectly sound way _inside my worldview_ to rebut them. Of course I can't from yours, but from yours I can't rebut anything at all.
Hence, we come to perhaps your key claim, "[Christianity] assumes more beliefs that aren't rationally justified." Here I say you're putting the cart before the horse. Christian theism gives a basis for taking rationality seriously at all; in your world view, reason itself is arbitrary, no better than a bare assertion.
I do thank you for the careful and interesting response, which clearly demonstrated you had read and thought about my points. I imagine you'll spill a deal of ink on this one. I'll do my best to get back to you when time allows. : )
@santosh,
I wish you had answered more of your questions, because I own myself still confused by what your core claims are. What is it we're modelling in the first place? You've admitted again and again that we can know nothing about the future to any probability, yet it seems implicit in much of what you say that it is the behavior of the universe, _including_ the future behavior, that we are modelling, and in that case, it contradicts the earlier point to suggest that one model is more rational than another. So I will have a hard time responding until we clear up this business about what it is that we are modelling.
"'But it seems that you're violating the minimality principle now by assuming NOT chaos.'
Incorrect, for the data I already have from the past, my current models are sufficient, and chaos is unsupported because I can observe order, as presented in my models which satisfy the observed data. "
Well, chaos in the _past_ is unsupported, but so is order in the future. So again, IF you're modelling the future, then it's certainly true that you're disobeying minimality. Probability theory is the science of creating models with minimal assumptions, and if you don't assume order, it certainly won't give you any form of regularity in the future just because you had it in the past. Since you're getting a different result, you're not being minimal at all.
Say you're told that there are going to be 1000 numbers printed. Say the first 10 are these:
1 4 9 16 25 36 49 64 81 100
An obvious model for the remainder would be that it's going to be n^2 all the way up. But this model certainly assumes a TON. If you want to assume nothing, then all you can assume is that there will be 990 more numbers and you know nothing about what they are.
On the other hand, if you DON'T mean that you're model includes a model of the future, then you still haven't given a vaguely adequate reason for why you don't turn your steering wheel the opposite direction from how you want to go, ever. Why always test only the (non-minimal) ordered model? Why not test the chaotic model sometimes? I don't mean the model where it was chaotic in the past -- as you say, that has been eliminated by observation -- but the model where it gets chaotic RIGHT NOW. You just haven't addressed this issue.
"This constitutes my world view, which contains zero assumptions, and as such I submit is more rational than the theistic worldview. "
Well, first, it doesn't contain zero assumptions. Unless you're just talking about modelling the past. But in that case, what does it even mean to say it's more rational? It's not making any claims, in that scenario, it's just a hobby. You make toy models of the past for fun. Hobbies are neither rational nor irrational.
@dexter, I find myself increasingly depressed at what seems to be a lack of interest on your part in actually reading my posts. This surprises me, because in your abortion thread, you showed yourself to be one of the more careful at doing this. Anyhow, I'll allow that they've been kind of long in this thread. Anyway, here goes, to your 7

, in order:
1) First, certainly there are good reasons from probability theory (the assumption of maximal ignorance) to assume that, if we have absolutely no reason to assume order, then disorder is probable. Most possible configurations of space, of spacetime, of matter, or of anything else are maximally disordered. This is an interesting field. One could motivate it fairly easily by pointing out, again, that if a ball is going through the air, and you assume it will keep going in the same direction (or curve in a parabola, due to gravitation), you are choosing one out of infinitely many directions, whereas disorder makes no such assumptions. Even if you break it up into finitely many, say 360 -- one for each degree -- you're choosing 1 in 360 degrees at each moment. The numbers add up to pretty bad for order pretty fast. This is the heuristic argument. It can be made more precise but the math gets dreadful.
But even assuming one could adduce no positive reason for thinking order unlikely, it seems to me the best one could do is be agnostic. You say there is no reason to believe disorder is more likely than order. Even assuming that (which is false), there's also no reason to assume the opposite, _but you do_.
The remainder of point 1 includes explaining to me what begging the question is (thank you, certainly, that was not something I ever encountered in law school) and responding to a charicature of my point.
2) This is extremely similar to point 1. But I'll just respond to one further thing. You claim that I am making an argument from ignorance. But you miss what I'm doing. I'm merely pointing out that _your_ belief has no support. I don't need to support the negation of your belief in order to do that. It is you who are making the argument from ignorance (which, by the way, thank you for defining for me).
3) I did not anywhere make the argument that the Christian God exists because it agrees with experience and intuition. Your refutation is therefore irrelevant, and constitutes the Straw Man fallacy.
4) I nowhere mentioned positive emotions or desires as an argument for the Christian God, or indeed, at all. Your argument is therefore what is known as the Repeated Straw Man fallacy.
5) I nowhere appealed to the fact that many people around the world believe in the Christian God, or even mentioned such. Are we now just running through some standard checklist you always go through when talking to Christians? In any case, given that I did not even so much as allude to this argument, your offering a refutation of it as a refutation of my argument constitutes what is known as a Third Straw Man, or in some circles, a Straw Man Hat Trick.
6) I did not make or allude to any of the various arguments which you attempt to refute in point 6, and now confess myself thoroughly mystified as to what you think you are responding to.
7) Ah! We're finally back on topic. I would be lying if I said I didn't enjoy that little excursion through irrelevancy, though. I of course understand the feeling of disappointment one feels when an opponent in an argument does not make the particular bad argument I was hoping, but I would still encourage you not to rush forward and refute it anyway. It only serves to confuse.
Anyhow, let's see here. Subpoints!
a) OK. Well, in this case, then indeed knowledge IS impossible. (One may choose to believe in such an irrational world view, of course, but then there is little point in arguing about it, because to argue suggests you put faith in reason).
(These remarks deal with a1-a3 as well).
b)
b1) Well, be specific. If you once decide that your worldview is irrational and decide to adopt a different one, yet decide not to adopt Christianity, we can discuss the rationality of your other world view at that time.
b2) "The universe does not need a god to make it rational"
Well, it could do whatever it wanted, of course, but we would have no source of knowledge to tell us we weren't in case a1. I think this addresses b2a as well.
b2aa). Umm, I don't think I ever said God HAD to create the universe. So yes, I'll sign onto this one.
b2ab) Dizzying -- isn't this the same as a3?
b2b) Isn't this the same as a2? Or is the difference that this time the universe is rational? In that case, see remarks attending b2, above.
Thank you, of course, for your further explanations of various formal fallacies that followed your main post.
As to your following post -- I feel inclined to respond, although as I'm sure you would want me to point out, disbelieving something because it is "negative" or "pessimistic" or makes one unhappy would be the fallacy of Appeal to Emotion. It's funny how perspective changes things, of course, but I think most Christians view atheism as pessimistic and Christianity as optimistic. Of course, I happen to agree with you that neither point of view has much to do with the truth of Christianity one way or the other, so I'm not going to spill many pixels discussing it. But anyway, a belief that the ultimate reality is good, just, and loving, instead of meaningless, does not particularly seem pessimistic to me.
As for the substance in this post, my point in some sense is this: your brain is not outside the world. Rather, it is part of it. You need not only to say that you view the world as rational or inevitable; you have to explain why such a view, coming from your brain, should be regarded as likely to be true. After all, you take a strictly naturalistic view of the brain and its origins, yet you are claiming to have to have got your hands on some very big metaphysical truths with it. I would love to hear how.
@ucla, Thank you for the post. The probability calculation you suggest only makes sense within some worldview. Within Christianity, of course the probability that God exists is 1. As an atheist, then it would be 0, but but so would the probability of order or reason being true.
As for FSM and other gods, I actually do not think they succeed in supporting rationality as does the Christian God (and the Christian world view).
In any case, my probability argument was a little more subtle than I think you are taking it to be, but since I'm not sure which argument exactly you're referring to, it would be hard to go further. In any case, it's now crazy late, and I've written an absurd amount, so I hope the answer to your objection lies somewhere up the page, because I am now going to leave (and probably not come back for a day or two, if I can help it).
Oh, oops, I forgot spyman's argument. OK, spyman, this might not be the highest quality, but let me not ignore you. Actually, rereading, I am not really sure I fully understand your points, but I'll try. Why is the probabilistic outcome of a coin flip unknowable? Making no assumptions, I suppose it's 50/50. While it's true that actually atheism would undercut things like probability as well, I didn't really go there, so I'm not sure I take your point.
In any case, I have never been arguing that the universe actually is disordered, or that reason actually is flawed. It's not, but that's because God does in fact exist.
Second paragraph: the reason it's the Christian God is because the other religions you mention don't actually succeed at supporting knowledge any better than atheism, for various reasons. Again though, once you're asking that question, you're already allowing that atheism is completely flawed and Christianity isn't. I don't think you're actually there, so why look at what else might not be, yet?
The rest of your post, I think, doesn't really engage the points I've made. Science rests on the assumptions I've been talking about. It cannot do without them. I understand how science works, but that's orthogonal to whether its assumptions are correct.
OK, and now I'm really off. Sorry to be a little on the long winded side. If I'm only going to respond sporadically, I'd like to try to actually respond, at least.
Take care!
