Not a serious one.
No one's personal belief is a serious threat to anyone else's.
It depends. Does it matter if a belief conforms to reality or not? I think so. In that case, a belief that better conforms to reality is always a threat to those less realistic.
I personally believe that all beliefs are underdetermined and that people believe what they believe for essentially aesthetic reasons. One likes an idea in more or less the same way that they like a painting or a piece of music.
But are
all beliefs like that? Is one's belief in mathematics, reason or science merely aesthetic?

Will Bouwman wrote: ↑Fri Mar 07, 2025 10:17 amIf you maintain that so many beliefs are false, you raise the question of what you can say about your belief that others couldn't say about theirs.
That it's actually true, of course. That's the difference.
Anyone can say their belief is true, believe it sincerely and argue doggedly, but the depth of faith has no bearing on the truth of the associated belief.
That is true: faith will not make an untrue thing true. But likewise, the refusal to have faith will not make a true belief false. Epistemology does not determine ontics. Rather, epistemology is only as good as it is conformable to reality.

Will Bouwman wrote: ↑Fri Mar 07, 2025 10:17 amMy point is that one should be able to accept evidence for human evolution or God, even if we are not persuaded by that evidence.
We should always look at the evidence, of course. What we should not do, and what the monkey-to-man chart models so clearly, is to assume a wanted conclusion and then work too assiduously at making the data seem to line up with it.
It's not clear to me that monkey to man charts demonstrate any such motivation.
Oh, it certainly should. There's no other motive for the existence of the thing. We know now for sure that human beings didn't come from monkeys, so there's no other source for that thing but fiction, based on insufficient indications from very thin "evidence."
Immanuel Can wrote: ↑Fri Mar 07, 2025 3:29 pmWhen the monkey-to-man view was exposed as foolishness, it immediately raises the question of what allegedly "scientific" men were doing in assembling the chart in the first place.
Scientific ideas develop and even change radically.
Yes: but wildly erroneous ones like that shouldn't appear at all. If sufficient evidence doesn't exist, then no theory at all should be sold the way the monkey-to-man thing was sold. It was in every textbook, all the museums, on t-shirts and coffee mugs...it become a pop meme, really, because it was so accepted as fact -- with the only problem being that it was complete hogwash.
The consensus among evolutionary biologists currently is that humans and other great apes had a common ancestor, which given the genetic and physiological similarities seems entirely plausible.
Three problems with that explanation of the monkey-to-man thing: first, that it was definitely asserted that men came directly from monkeys, which they did not; secondly, that the "common ancestor" proposed even now is a very early "pre-ape" kind of thing, perhaps back as far as the primordial soup; and thirdly, it makes the very obvious mistake of assuming that genetic similarity argues for causality. But on that third thing, we should note that all living things share a huge amount of genetic similarity, and yet not all are proposed to be "ancestors." In fact, as Pfizer (yes, that Pfizer) notes, we "We’ve long known that we’re closely related to chimpanzees and other primates, but did you know that humans also share more than half of our genetic material with chickens, fruit flies, and bananas?" I don't see any chicken-to-man or banana-to-man theories floating around...do you?
Now, even if, say apes are closer to humans genetically than are bananas, all it would imply is that apes and men were composed of from the same elements, not at all necessarily that it's more probable that one came from the other. The old correspondence-causality fallacy applies here: we can't deduce causality from similarity. And since Genesis insists that man was not created
ex nihilo, but rather "out of the dust (or substances) of the earth," it's utterly unsurprising to find similar elements of composition in many life forms, including apes and fruit flies.
Immanuel Can wrote: ↑Fri Mar 07, 2025 3:29 pmNow, that's some historical evidence that deserves some inspection, for sure.
What is the evidence?
That what passes sometimes as "science" in the public mind can be quite fraudulent, when unscrupulous popularizers jump on it. The monkey-to-man thing is an excellent example of pseudoscience being treated as complete scientific orthodoxy, and skeptics being ridiculed for not believing it, when it was hokum from the start.
Immanuel Can wrote: ↑Fri Mar 07, 2025 3:29 pm...since you are an Atheist, it must be the case that whatever data you know of conduces to that view.
No, it is rather that the data suggestive of God is only compelling to someone wishing to believe it. I have no wish to believe in any particular god, so I don't. That should not be understood to mean I wish not to believe in gods.
Well, the real God is certainly a very particular one: so if you don't wish to believe in particular gods, it seems to me that that means the same thing, effectively. However, there's a point worth making about data here: nothing is evidence for somebody who's already committed to the proposition that there will be no evidence. Evidence has to be recognized AS evidence; otherwise, maybe it exists but cannot be recognized.
So let me assume you that you're an Atheist, or at least an unconvinced agnostic.
If there were evidence for God, what sort of thing, what sort of practical demonstration, would you recognize AS such evidence? In other words, are there any conditions under which you can conceive of yourself being convinced of the existence of God?
I don't need any evidence that God does not exist to not believe that he does.
No, of course: one can believe whatever one wants to, or refuse to believe whatever one chooses to. But then, your skepticism must be non-evidentiary, and not applicable to anybody but yourself. Thus, it would reduce to the claim,
"I personally lack belief in God," which, to me, would have to be the least surprising claim you could make. Of course you lack belief. If you say you don't know anything about God, I have to believe you.
But it doesn't go very far. If I "lack belief" that Detroit exists, that's a "me" problem, not a "you" problem; and it doesn't mean Detroit doesn't exist, or that, if I were less unreasonable, I couldn't also devise any test to prove the existence of Detroit. It just means, "I lack belief in Detroit."
In the same way, "I lack belief in God" is a very inconsequential claim. It doesn't tell me that I'm obligated to lack that belief, or that anybody else is. It doesn't even tell us whether you could change your mind in the next five minutes. All it tells us is that, at this second, you lack something.
...you choose to interpret substantially the same evidence that I have differently.
That's an interesting claim: what made you think you knew already what evidence I -- or anyone else, presumably -- could possibly have?
Immanuel Can wrote: ↑Thu Mar 06, 2025 2:30 pm"One random mutation inevitably extinguishes all chance of reproductive viability"? I never said any such thing, and in fact, believe the opposite: that there should be many, many cases of "false start" animals that were only eliminated after many generations.
I can't imagine the logic by which you arrive at that conclusion. Why, for example, should a species that survives for many generations suddenly be eliminated?
When another branch of that species more "evolved" than it appears on the scene, the theory has to hold that it would occasion the extinction of the previous "less evolved" one. If not, the theory would make us expect we'd be neck deep in actual Piltdowns, Javas and Peking men. And clearly, we're not.
Immanuel Can wrote: ↑Fri Mar 07, 2025 3:29 pmIn fact, given the purported timespan of billions of years, there should be much more variety than we see, plus mountains of fossil evidence of defunct evolutionary "tries."
That would require fossilisation being much more common than it demonstrably is.
Not at all. We're talking proportions here. Given the existence of billions of years of false starts, it's vastly more probable that however many fossils we have, they'd almost all be of the various false start "ancestors" that survival-of-the-fittest is supposed to have killed off. There are supposed to be innumerably more of them than of the "survivors."
Immanuel Can wrote: ↑Fri Mar 07, 2025 3:29 pmThe Fine Tuning debate is where you'd want to look for those odds...and they're most impressive against the possibility of any life existing at all...let alone a balanced and life-promoting universe populated by intelligent observers like human beings.
Among the problems with fine tuning arguments is the assumption that various constants have an arbitrary value that could be otherwise.
You have the argument backwards. Fine Tuning implies there are NOT many other possible constants that would produce life, not that they "could be otherwise."
We simply do not know enough about the nature of the substance of the universe, or even if the universe is in fact substantial, to support any such claim.
That's certainly not the case. We can, and have, measured all sorts of these things like the strong and weak forces in the atom, the gravitational weights and spacings of the planets, the rate of expansion of the universe, and so on. And in fact, secular scientists, whenever they are not thinking about the implications, often point out the miraculous fineness of the very "tuning" to which the Fine Tuning Argument refers. (See, for example,
https://slate.com/technology/2013/08/sy ... exist.html)
The facts aren't in doubt: the willingness to make the logical and necessary conclusion, though, certainly is.
