What if I’m wrong? (2023)

> each of us should examine our own beliefs, and not only ask "What if I'm wrong?" but "How would I know if I were wrong"?

The final arbiter is repeatable verifiable data. Everything else to subject to doubt.

So how would I know if naturalism is wrong? God could come down again in a public revelation and agree to undergo a scientific scrutiny His nature. Who can then deny His existence?

Lacking that, how do I know religion is wrong? Well, religion plays two roles: a source of strength in this world full of suffering, and an explanation for our existence. The former is necessary for many people and will probably never go away. But the second role has always been that of a "God of the gaps", with the gaps drastically shrinking with improving scientific knowledge. All arrows are point to a naturalistic explanation of the universe. So pending some strong "evidence", none of the religions seem to be correct in the second role. To me, it is better to say "we don't know yet" than accept something on "faith", especially when it comes with seemingly arbitrary commandments on practical matters of life.

> instead of this being evidence that there were supernatural beings of some sort

This is a good point. I think this would make sense if there was some sort of consistency in these claims. However, almost every religion assert their own mutually exclusive claims on how the world is, and wants us to take up those claims on faith. It is easier to consider these claims as wish-fulfillment of the first role I mentioned above, than any sort of proof for actual divinity.

FWIW, I'm a Christian (convert to Catholicism) and I respectfully but completely disagree with the GP when he says:

>> If Christianity was a conclusion reached after a set of rational arguments, you would be right. But belief in Christianity is sort of logically prior to rational argumentation. Of course, we have Christian apologetics, which make arguments for certain aspects of Christianity, but this isn't really the reason to believe so much as it is just motivation for people who think in more intellectual terms to take it seriously. Faith is beyond the domain of human reason - the Christian's belief is founded in a kind of immediate, self-evident spiritual experience that comes logically prior to arguments. We might still discover internal inconsistencies that might motivate us to rethink this worldview, of course.

I respectfully disagree with every sentence (except the last).

Firstly, I think God's existence can be proved rationally, using arguments that take very basic empirical observations as premises (for example: "things change", "things behave predictably", "there are multiple instances of the same thing"). I don't think these are arguments that fit into a combox, which is frustrating but that's the reality -- although I think most of the common arguments against God's existence can be dealt without many words.

Secondly, once God's existence is established, I think the empirical basis of Christianity specifically (evidence for the resurrection) is sound. I think the common objections fail. Many of the objections are variants on Hume's, which amounts to "the resurrection is so unlikely given my philosophical assumptions that literally any explanation for the observed facts is more likely". Once Hume's assumptions are undermined (in stage 1), the facts take on a very different light.

Thirdly, I think Catholicism is internally consistent and has further evidence in its favour -- including miracles, continuity of institutions and continuity of teaching -- whereas I think Protestantism and Eastern Orthodoxy lack these qualities. While intra-Christian disputes may seen beyond the scope of this discussion, I think they have some bearing. For example:

>> Faith is beyond the domain of human reason - the Christian's belief is founded in a kind of immediate, self-evident spiritual experience that comes logically prior to arguments.

This is a specifically Protestant view (although many Catholics mistakenly hold to it since it chimes so easily with the post-Enlightenment concept of religion). I would say faith is a rational assent to revelation. But more importantly for the present discussion, I would say God's existence that can be established by pure reason, independently of faith.

> "I" exist. Presumably the universe I experience also exists. Why? There's a First Cause that brought them into existence. We can call it God. This is the closest religion and science can get, because this definition of God is without any pre-defined qualities. For instance, God can be non-dualistic (God _is_ the universe, or in other words, the universe is its own cause), and even mathematical (Physics' Theory of Everything, Mathematical Universe Hypothesis). We only have a set of possibilities here.

There are solid arguments against all these and in favour of monotheism. Again, no way of summarising in a combox, but I can give a few thoughts, which should not be taken as even an adequate description, let alone a complete defence that is intended to convince you :-).

Pantheism is false because it can't explain change. A thing can only be changed by something else; therefore the first principle (First Cause) of reality can't change, because otherwise it would not be first. But the universe is changing; hence the universe can't be the first principle of reality. Each of these points is obviously controversial, but I think defensible.

Alternatively one could argue that change is an illusion, like many eastern religions do. But speaking very generally, one object is distinguished from another by how it changes (that is, how it acts or is acted upon). We distinguish the presence of hydrogen from that of helium by how they act, or how other things act on them. We also distinguish a human being from a dog by how they act -- not least, how they act on our sight, sound, etc. And so on. If change (that is, action and being acted on) is an illusion, it means that individual objects (like stones, trees, dogs, human beings) are not actually individual at all; their individuality is only an illusion. But if this is so, predication is impossible, because we are predicating only of our illusions. Since this is not so (because if it were, why are we even bothering with this discussion?), pantheism must be false. Such is the vague outline of another argument that a monotheist would make.

Alternatively one could argue that a thing need not be changed by something else -- that it can change itself. The trouble with this is it fails to explain why things act in one way rather than another. If things could change themselves, they would act completely randomly, because there would be no cause of their change, and therefore no reason. This is not so.

Pythagoras was the first to propose that mathematics was the basis of everything. But there are things that are not numeric or can be reduced to number. For example, non-mathematical logic, which is a fundamental aspect of reality, and can't be reduced to number. Again, a counter-argument would proceed on these lines.

I'm not going to attempt any other answers in a combox because these are profound questions that require, and have received, book-length expositions. I am only attempting to give you the vaguest idea of the thought processes I go through in arriving at my beliefs. But I have not yet found an argument that makes me doubt my Catholicism, and I think it's profoundly false to say that Christianity is independent of logic or observation.

I think the context matters. The original context for all of this is whether from the perspective of the Christian, in thinking rationally for himself/herself, must have an argument for Christianity. I think the answer is no, just as the atheist, in thinking rationally for himself/herself, does not need an argument for atheism. I think the context of a generic discussion of Christianity is different - if we set the topic of our discussion to be whether Christianity is true or not, then yes, obviously we cannot just take its truth as a premise.

Maybe I'll draw an analogy - a foundational premise of science is that the past resembles the future. If we determine certain laws of nature based on past experimentation, that's not going to change in the future. Does the scientist, in thinking rationally for himself/herself, need to have an argument for this belief? I don't think so - the scientist can go on analyzing and understanding things scientifically through the scientific worldview without ever needing to construct an argument for this foundational premise. He/she is, however, on the lookout for contradictions - things or events that science can't explain or seem to defy science. I don't think I've described an irrational person here. Of course, if we have a discussion about the enterprise of science and its validity as a whole, then it may come to questioning this premise. But does a scientist in doing science have some kind of burden of proving this premise? I don't think so, just as the Christian in looking at the world through the Christian worldview does not have some kind of burden of proving Christianity.

>I present some of my own thinking below... What you've outlined here is actually firmly in the scope of natural theology, the project of establishing certain theological claims through human reason alone, though not all Christians agree that this project is successful. You may be interested in section 5 of chapter 2 of The Blackwell Companion to Natural Theology that addresses the Gap problem, which is exactly what you've described, the problem of the gap between the conclusion of a cosmological argument, i.e. the existence of an ultimate cause, and the traditional omnipotent/omniscient/omnibenevolent God.

Christians who don't buy natural theology would instead just say that God and His most important properties are self-evident through spiritual experience. (Even Christians who buy it would agree, I think, that this purely rational project doesn't really get you to the fullness of Christianity, and that spiritual experience is key to having the fullest sense of who God is, the presence of Christ here today, our role in the world, etc.)

As to your last point about whether we're being tricked, it is true that we cannot have certainty about these claims. Uncertainty is part of the human condition. But that doesn't prevent us from having knowledge of things. I know that there's a floor beneath me, even though I don't have a certain proof of it (it's not necessarily true - I could be dreaming, there could be an evil demon feeding me false sensory data, etc.)

>But I do get interested whenever religion wants to be an exclusive arbiter of reality and what's right or wrong. And every time, I have found it to fall short of all its claims.

Well, religion being an exclusive arbiter of reality is only something held by a fringe group of religious people I think. Most reasonable religious people will have no problem with mathematical proofs or scientific evidence revealing things about reality. Many religious people will also accept that those of other religions can have knowledge of moral truths. But if you just mean that religion wants to be the ultimate truth, well, yeah, it does.

> I think God's existence can be proved rationally

We have to be careful here by what "God" means. God as in a First Cause is trivially true, but is not what most people mean when they say God. The existence of the God of religions, i.e., a personal all-loving human-caring God who listens to human prayer can only be shown true or false empirically. In my comment, I posited alternative universes, for example, the Devil acting as God. Which universe we actually live in among a large number of possibilities is not something that can be proved rationally.

> empirical basis of Christianity specifically (evidence for the resurrection) is sound

Yeah, I remain unconvinced and give higher explanatory power to human affinity for divine miracles (see followers of modern age "gurus"), ability of hearsay to go "viral" (especially in an era without books and modern scientific knowledge), and a new religious movement asserting stories for a "greater good".

In addition, as I already mentioned, even if the resurrection is true, the only thing we can be sure of is that certain "magic" can go beyond the usual laws of physics. That's it. There could be a number of reasons behind the resurrection. The Devil playing games. The Matrix scientists testing a "what-if" scenario. A fallible God trying to do some good. And of course, a genuine all loving God.

Christianity would have been so much convincing if Jesus had mentioned at least a few futuristic but concrete facts that only God could know, and that future generations could verify happened exactly as written in the Bible.

> A thing can only be changed by something else

I can only say, why? :) By a universe, I mean a set of physical laws and a bunch of stuff those laws act upon. Nothing prevents say a cyclic universe where both laws and stuff exist without a beginning, just evolving from big bang to big crunch to big bang, repeated ad infinitum.

I'm not who you replied to, but the reason circles are ellipses is because the definition of a circle is equivalent to the case of an ellipse where both foci have the same x, y coordinates. You can read about all the definitions of an ellipse on Wikipedia.

https://en.wikipedia.org/wiki/Ellipse

Functionally, they might not be the same if you're programming them. For example, if you have a circle class with members detailing its center and its radius, it might be more efficient to draw an instance of it than an instance of an ellipse class that has two foci members that just happen to have the same values.
