Creationists: How do you test for "truth"?

That you can make such a ridiculous statement is a sign of just how ignorant you are. Verificationism is unverifiable -- that's the first problem. The second problem is that it is impossible to verify anything. Let's suppose, for example, that you made the claim: "Trump traveled to Japan recently." We want to verify that. How do we do so? Well, we could ask you how you know that and you might say: "Well, I read it in the Washington Post." This requires us to 1) verify that it was actually the Washington Post and 2) verify how the Washington Post got its information. Assuming we ignore 1) for the moment and simply focus on 2) that would require us to call the Washington Post and get someone on the phone who tells us that WaPo got the information from the US Press Secretary. That requires us to verify that it really was the US Press Secretary and to determine how the US Press Secretary got his information. On and on, back further and further we must verify the verifications and there is no end to this process. It's called an infinite regress.

Nothing above addresses the issue of verification in science. Verification is the testabiity. repeatability and predictive value on the results of scientific methods on the nature of our physical existence. Historical academic methods would be used in the above, and not Methodological Naturalism. Your reference here to infinite regress is bogus.

Again, most of your claims have been debunked decades ago. You might start at verificationism or you could just read This article, which points out: "The statement that it is good, all things being equal, to believe what is true...is not itself...verifiable." So if I really accepted your philosophy, I would have to reject your philosophy.

It is not my philosophy. Your unc reference does not refer to the scientific application of verification. I see no author nor publication information in the 'the article'? you referenced. Based on the I would have to consider it bogus fabricated. I reference recognized academic sources like the Stanford University Encycopedia.

Science is verifiable because the knowledge can be confirmed by repeated experiments. Historical events cannot be verified by the same methods, because they are not verifiable by scientific methods. The have to rely historical academic methods of recording and confirming historical events,

All of this is beside the point. I merely indicated that theory of Biblical inerrancy only applies to the autographs. Showing a mistake in the KJV, for example, is completely irrelevant to the claim of Biblical inerrancy.

The original autographs are not historically known to exist.

Polymath257 said:
What I am proposing is a 'convergence' model of truth: truth is what minimal assumptioned, testable theories converge to in the limit.

I would probably go for a combination of a 'convergence' model of truth and a correspondence theory of truth, and often expressed as harmonious combination with practical consideration of models of truth:

From: The Correspondence Theory of Truth (Stanford Encyclopedia of Philosophy)
the label is usually applied much more broadly to any view explicitly embracing the idea that truth consists in a relation to reality, i.e., that truth is a relational property involving a characteristic relation (to be specified) to some portion of reality (to be specified). This basic idea has been expressed in many ways, giving rise to an extended family of theories and, more often, theory sketches. Members of the family employ various concepts for the relevant relation (correspondence, conformity, congruence, agreement, accordance, copying, picturing, signification, representation, reference, satisfaction) and/or various concepts for the relevant portion of reality (facts, states of affairs, conditions, situations, events, objects, sequences of objects, sets, properties, tropes). The resulting multiplicity of versions and reformulations of the theory is due to a blend of substantive and terminological differences."

You miss the point. In the example the elephant is blue ─ painted blue, if you wish ─ but your book says the elephant is pink ─ painted pink, if you wish.

You assert that because your book says it's pink, it is not blue and it is pink.
No, I did not. The only thing you have proved is an abysmal lack of reading comprehension skills.

I said that if one simultaneously believes (or claims) that all elephants are blue and that he (or she) has a pink elephant in his basement, then he is making incoherent statements. An incoherent statement is false. Not once did I talk about any book. That's your pathological attempt to project Christianity on me.

I know what the Nicene creed says. And you know that it doesn't define God in any way useful to the question, How can we determine whether phenomenon X is caused by God.
Here we have another case of special pleading. You want to know how we can determine whether phenomenon X is caused by God. Fine. But when I ask how you know that the fuzzy outer portion of your picture is caused by an electron, you claim that I don't know what I'm talking about. What we are noting here is confirmation bias. Statements or pictures that support (or you think support) your claims and theories are given inordinate weight whereas those that tend to refute your claims and theories are ignored.

And you further know that you don't have such a definition, the definition of a real god such that if we found a candidate we could tell whether it were God or not.
That's an interesting statement. But is that statement verifiable? Please indicate the process you undertook to verify the truth of that statement.

In 'my system' there are no absolutes, which matches reality where there are likewise no absolutes. And because science reaches its conclusions by empiricism and induction, its conclusions are always tentative. Nonetheless, science continues to make progress, in a manner with no equivalent in religion.
In your system there are no absolutes? Really? So if I said: "The cause always precedes the effect, temporally" you would say that this is not absolutely true? Would you also say that the statement "In 'my system' there are no absolutes" is not absolutely true?

I have no idea why you regard the absence of absolutes as a 'flaw'. Do you think the idea of absolutes is Jesus? Or is coherent? God isn't omnipotent.
You say this because you have no understanding of the word 'omnipotent.' Huge debates were carried out centuries ago as to exactly what was meant by 'omnipotent' in the concept of God. Theologians debated whether God could create a rock he couldn't lift or how many angels could dance on the head of a pin. You seriously want to revisit all of that?

He can't make a perfect copy of himself, for example. And if God is omniscient then he knew every letter of this conversation, every thought process in your head and mine, every temperature gradient along the wires that connect our computers ─ and he knew that before he made the universe 14 bn years ago, meaning that theological freewill is a nonsense, and you and I have not the tiniest possibility of deviating from what he infallibly foresaw.
God didn't make the universe 14 billion years ago. That's all part of the falsified Big Bang theory.

And if God is omnipresent, then for 14 bn years or so he's spread himself across maybe 10^24 stars and all their planets, and all the evergrowing space in between, which seems like a wonderwork of inefficiency for any god, let alone a personal god.
I fail to see the relevance of this discussion. It's more of a personal rant than anything that has to do anything with me.

I've already pointed out to you that "Under the correspondence definition of truth, truth is correspondence with reality" is true, and is the only claim I've made.
Go back and re-read your original post.

I didn't make the claim that all knowledge comes through sensory input. We're born with an extensive kit of instincts, for example.
Sure. Like we all instinctively know that God exists, right? Or perhaps some of us have different instincts than others? Maybe you were born without that instinct. How do you know that the instincts I have are the same instincts that you have? How do you know that what you instinctively 'know' corresponds with reality?

But we get our information about the external world through our senses. Information is not knowledge until the brain processes it.
Not necessarily. People can arrive at truth through pure reason. The entirety of math is an example.

Nor can you say the blue elephant is pink because your book says so.
There's no book. Can't you read and understand?

So your Jesus is truth method is incapable of telling us whether S: Freetown is the capital of Liberia is true or not. All facts not mentioned by Jesus, including your own name, are likewise unknowable. The time your plane leaves, the existence of Moscow or New York, the presence of oxygen in the air, the truth or falsity of any statement at all about the world since 30CE or so, is unknowable, you say.
Depending on one's philosophical bent, one might argue that all of these are irrelevant pieces of information. To a Christian, salvation is the end all be all of existence. Such a Christian might argue that the time one's plane leaves has no effect on one's future relationship with God. Accordingly, even if one cannot know what time one's plane leaves, or if one misses it, or even if one unintentionally takes poison and dies, this does not affect one's afterlife.

It therefore means you're never in a position to contradict anything I say ─ you have no way of knowing whether it's correct ('true') or not.
No, not "you" as in I. A Christian.

Like the report of an angel sighting you previously mentioned, the claim is capable of investigation, to reach a fair conclusion from the evidence.
No, the claim is not capable. Claims do not have capabilities. People have capabilities. Even computers have capabilities. But claims do not have capabilities.

In this case, since there will (I take it) be no examinable evidence, and the matter is satisfactorily explained by your acculturation, you'll need something extra by way of satisfactory demonstration to get a conclusion in favor of your claim.
This presupposes that evidence is important. What evidence do you have that evidence is important?

You appear to be unaware that the word 'Earth' and the phrase 'the earth' can refer to the planet Earth.
No, you seem to have missed the entire point of the thread. The Bible defines Earth as 'dry land' and then says that said 'dry land' was flat. Then you want to argue whether the globe was spherical at that time. This is, by far, the most idiotic argument I've ever heard.

It's highly relevant to the bible tale of Genesis creation. We can even put a rough date on when Yahweh was invented.
This presupposes that Yahweh was invented. How did you verify that Yahweh was invented? You do believe in verificationism, don't you?

On the contrary it's the crux of our discussion. You refuse to look at the elephant to determine its actual color, because you prefer the answer in your book.
There's no book. Can't you get that through your thick skull?

You're a really sore loser, aren't you. I show you a lab image of a real electron and you invent a blustery excuse instead of saying Sorry, I was wrong. I now understand electrons exist in reality.
That's not a picture of an electron. Even the article itself says that it's not a picture of an electron. It says: "What you’re looking at is the first direct observation of an atom’s electron orbitalan atom's actual wave function!"

What we have here is deep seated confirmation bias. You see a picture of something that might (or might not) be a confirmation of what you believe, and so you insist that it proves you right. It proves nothing. You should seriously read polymath's recent post on the problem of induction and the need for falsification. He's wrong -- but he's light-years ahead of you!

An electron is not a tiny ball bearing, it's a negative fermion with 1/2 spin, and presents with both wave-like and particle-like properties. You can see it in the image as the outer ring of dots.
Speculation.

Science is great at coming up with mathematical descriptions for "how" nature behaves. Science never answers why does nature behave at all? Why does any energy exist at all as opposed to nothing? What is IT that decides which quantum state is realized upon observation?

I very much appreciate how science has dispelled countless silly superstitions over the last 200 years. But science is not closer to getting rid of the need for religion that before it became popular 200 years ago. Yes, the laws of physics and nature are relentless in following certain patterns of behavior. But science is no closer to answer "why" than ever before.

Religion may have failed in answering "how" nature behaves, that is, by supernatural causes. But the idea of religion as a way for answering the "why" questions is still valid. Not everyone is a nihilist. Not everyone believes on the cosmic timescale everything in our lives is just meaningless patterns of energy swirling around where no one pattern of energy is any more important than any other.

So you in my mind, your idea of a 'convergence' model of truth may exist, could exist, and I doubt it would answer my important "why" questions.

The other problem with the idea of having a 'convergence' model of truth is I would have a hard time accepting it's accuracy and completeness with regards to every possibility in nature.

It is important that the 'why?' question is NOT a question for Methodological Naturalism, and the concept of convergence in science could not include metaphysical questions nor 'why?.'.

Which only shows you don't understand what you saw.
This post only shows that despite your previous rhetoric about testability and falsifiability, you don't actually believe in it. It's just a thin philosophical veneer that you spread over the real nonsense that you peddle.

Well, one issue is that any *fundamental* description of things cannot have an answer to 'why' it is that way. Any answer to the question 'why' will rely on even more fundamental reasons or laws.

So, why do you expect the question 'why' will have an ultimate answer? Isn't it ultimately impossible to get such by the very nature of explanation?

On the contrary, what the picture showed was an electron orbital. That is precisely what is to be expected given the basics of quantum mechanics. Why you think it *wasn't* a picture of an electron is my question.

Poor understanding of the nature of science. Math doe not arrive at truth through pure reason.

Math evolved for very logical and practical reasons as part of the human logical tool box to apply it to the nature of our physical existence. Math in and of itself is neither true nor false. It becomes useful in science and our everyday world when is practically descriptive of the our physical existence. It is a tool not truth in and of itself,

Let me summarize your argument to see whether I have understood it.

You have a theory of an electron, hereinafter ("T")
This T predicts certain observations ("O").
You observe O.
You conclude that T is correct.

Isn't this a classic example of the affirming the consequent logical fallacy? Doesn't this violate the very problem of induction that you previously referenced? The most that you can say is that your theory was not falsified by the test at hand.

Your argument presupposes that evolution occurs.

However, it is a simple matter to demonstrate that truth can be arrived at through pure reason. Imagine that we contemplate the idea: "Absolute truth exists." If we start by assuming that this idea is false, we can say "Absolute truth does not exist." However, by saying that, we are claiming that the claim that "Absolute truth does not exist" is absolutely true. Since we have reached a contradiction, we know that our initial assumption was false. Therefore, we have demonstrated that absolute truth does exist through a process of pure reason.

No I do not, nor does science. Math obviously evolved from the human practical logic of counting things to the math of today for practical reason to describe reality. Any absolute nature of math beyond this requires a philosophical/theological assumption.

Science nor I have ever addressed the question of whether absolute truth exists. It is an open unresolved question. The philosophy of science makes the assumption that the nature of our physical existence is uniform and predictable. The testing of theories and hypothesis tests this assumption, and up until the present has not failed.

From the philosophical perspective I believe absolute truth exists. If God exists, absolute truth is an attribute of the nature of God. If God does not exist absolute truth would exists the ultimate underlying nature of our physical existence.

Again, that is one theory and one observation. Suppose we have 20 different theories, all predicting different things and just one of them gives the correct prediction. At the very least, we know the others to be wrong. Now, we do NOT know the one that passed is correct, but if we do enough tests, we gain *confidence* of that theory within the limits where it has been tested.

And *that* is a reasonable process. That is why speculation (hypothesis formation) and testing are BOTH crucial. And yes, this is *exactly* the process of induction: how do we go from multiple observations not contradicting a theory to the validity of that theory?

The answer, of course, is that we can *never* be 100% sure we have it right. We can never know that the patterns we have found so far don't fail on the next test. We can never know that when we get more accurate tests, the theory will fail. But from extensive testing, *and attempts to show the theory wrong*, we can gain more confidence (Bayesian statistics helps) in the realms we have tested.

And that is quite enough to say that evolution (changes in species over time) is clear. it is enough to show that the universe was once hot and dense and nuclear reactions were happening everywhere causally connected to us. It is enough to support science as it is done.

Yes, ALL scientific views are, ultimately, tentative. But we can have very high reliability, none-the-less.

if you want proof, go into mathematics or alcohol.

I said: Your argument presupposes that evolution occurs -- to which you respond, "No I do not"? Do you even understand the statement that I made?
I'm not talking about you. I'm talking about the argument. We can know whether an argument involves an assumption by using the negation test. If we put the negated assumption as a premise, you can see that the argument fails:

P1: Evolution does not occur.
P2: Math evolved for very logical and practical reasons as part of the human logical tool box.

Science nor I have ever addressed the question of whether absolute truth exists. It is an open unresolved question.
No, it is not. I just proved that absolute truth exists.

The philosophy of science makes the assumption that the nature of our physical existence is uniform and predictable. The testing of theories and hypothesis tests this assumption, and up until the present has not failed.
Untrue. Imagine, for example, that someone is testing the speed of light. On his first experiment the speed of light comes in 80% of the expected value. That person rechecks all of his instruments and then retests. Now the speed of light comes in at 100% of the expected value. There are two ways to explain this:

1) The speed of light varied during his test, or
2) Something was wrong with his instruments.

You have no way of knowing which was the case.

From the philosophical perspective I believe absolute truth exists.
You don't need to believe it. I just proved it.

Metaphysics isn't a science. And science doesn't deal with metaphysics.

Whether the questions of metaphysics are 'reasonable' or not is a matter of opinion.

Like, for example, if there were a theory that predicted that light were a particle and another theory that predicted that light was a wave, then I could test and show that light had properties of a wave, thus falsifying the theory that light is a particle? Interesting.

That's very interesting. You claim that Bayesian statistics can help you solve the problem of induction. Why don't you provide us with an example, complete with the math involved?

No, this is speculation. Even though I might agree with some (or all) of those claims, it is not knowledge.

Science is like the following story.

A certain man was found dead in his apartment. There was a pool of blood around him and a nearby pistol. Experts were called in to examine the scene and shortly thereafter, a report emerged.

1) The man died from blood loss and a collapsed lung.
2) The blood loss and the collapsed lung was due to a lead projectile passing through the man.
3) The lead projectile passed through the man because it was traveling at a high speed.
4) The lead projectile was traveling at high speed because of a gunpowder explosion.
5) The gunpowder exploded because it was compressed inside a brass casing that would explode if tapped sharply on one side.
6) The pistol contains a hammer that could tap the bullet sharply on one side.

Skeptic: Yes, yes. All well and good. But who fired the weapon?

Science: There's no need to postulate an intelligent actor. We have identified the natural causes of death. We do not need to postulate supernatural, intelligent beings taking action.

Skeptic: Surely you must realize that an intelligent actor need not be supernatural. It might well have been his wife, a thief, or an estranged lover. Your explanation doesn't answer the vital question at hand.

Science: All explanations must stop somewhere. If we postulate an intelligent actor, such as a wife, we must also ask ourselves what intelligent actor created that wife? Then we must also think about who created the being that created the wife? And who created that being? On and on, we would never get to the beginning of questions. It's best to stop with the natural explanations.
