It is based on Lebesgue integration, where a probability is a measure (as used in Lebesgue integration theory).Well, ok. What are the axioms? I don't think you really want a full discussion of that.
crashfrog writes:
Mathematical induction is very different from the philosophical induction that we are talking about here. Mathematical induction is deductive.I've done mathematical induction, many times, and I can assure you that theorems are used. Jesus was a liberal hippie

Presumably that depends on the science.Not the axioms for the math, the axioms for the science. The statistical inference is just using a mathematical modeling tool to handle data.

The Peano axiomsIf you insist. So, then, what are the axioms? Jesus was a liberal hippie

You seem to be arguing against a position that nobody actually holds.

I have been presenting a position throughout the discussion. You, like the other participants, have ignored it. Apparently, you are unable to see it.I'm disappointed that, four years in, you're not yet prepared to actually advance and defend a position. Jesus was a liberal hippie

Completely off topic for this thread, so I shall continue to ignore it.
If I put a piece of potassium in a glass of water what does science tell us will happen?
I was not refuted there, nor elsewhere. Jesus was a liberal hippie

I am not playing games.But someone who is just interested in playing games would respond as you've been doing - by asserting that nobody understands what you mean, but not doing anything that would help them understand. I have not suggested that "nobody understands." Rather, I have said that it appears to be invisible to them. I make clear statements that nobody responds to. Then I later point out the message, and still nobody responds. I don't know why it is invisible. I suspect that it is drowned out by the unstated assumptions that you and others are making - and you are probably not even aware that you are making unstated assumptions. I recognize that I have not been a successful communicator on this topic. I'm moving on. I suggest you do likewise. Jesus was a liberal hippie

However, no such thing has been demonstrated.Straggler gives a great example of someone who's actually engaged in the debate, not playing a game: quote: I have no doubt that you believe it has been demonstrated. Most of the people in this forum are true believers in the religion of inductionism. What's sad, is that you have abandoned your critical thinking skills. You present pseudo-arguments that are based on jumping to conclusions, and claim that you have demonstrated something. That you believe induction is used is fine. You are entitled to believe that if you think it gives the best explanation. That you present wishy washy non-demonstrative arguments, and claim that they are demonstrations - well that's a problem.

crashfrog writes:
No actual "demonstration" has been provided, so there is nothing to show wrong.If it was wrong, and you were someone who debated instead of playing games, you would show that it was wrong. How about you present a real argument. Start with clearly stated premises, so that there is something asserted that could be challenged. Then provide the logical deduction from those premises to the conclusion. All that has been presented are woo woo arguments with no actual evidence. They are argument of the form "it just must be so".

I'll take that as an admission that you are playing games.Debaters talk about their positions. Game-players talk about the debate. [Message 695] Jesus was a liberal hippie

I am not trying to prove a negative. I gave reasons to doubt induction. I'm awaiting evidence from induction supporters, that it is actually used.So, can you demonstrate that no inductive reasoning is ever used in science without using inductive reasoning? The reason to doubt induction is there in the text I quoted from SEP, in Message 600. Namely, "all observation is selective and theory-ladenthere are no pure or theory-free observations." If induction is used to form a theory, then the observations must have been made before the theory emerged. That requires that observations be theory-free. If observation is theory-laden, then the theory is used in making the observations, so the observations did not precede the theory. Jesus was a liberal hippie

Straggler writes:
Which key feature? If you mean falsification, then that is usually taken as intended to help decide between science and pseudo-science. If it doesn't work for that (and it doesn't), we should abandon it.You advocate Popper’s view of non-inductive science but without the key feature of his thesis required to overcome the need for induction. When was the last time that an accepted scientific theory was falsified?
Straggler writes:
You are making stuff up.You advocate instrumentalism without the key tenet of instrumentalism which is that a theory should be judged solely on it's ability to accurately and reliably predict the behaviour of nature in a way that is useful Jesus was a liberal hippie

You are mixing two things. If induction is not actually used, then falsification is not required in order to overcome the (non-existent) need for induction.I'll agree that Popper's claim to having solved the induction problem rests on his falsification thesis. On the other hand, Popper did claim that his falsification solves the induction problem, and I have agreed that he was wrong about that.

I challenge you to provide a positive position. nwr writes: When was the last time that an accepted scientific theory was falsified? Straggler writes:
You don't say which theory. I'm guessing that it was actually an hypothesis that was falsified, rather than a theory. Theories are not hypotheses, and hypotheses are not theories, though sometimes a successful hypothesis can lead to a theory.But here is an example of the scientific ideal as quoted by Dawkins: ...

Straggler writes:
No.So you agree with non-inductive form of science advocated by Popper ... I agree with Popper's claim that induction is not actually used. However, I don't otherwise agree with his philosophy of science.

You reject that without even saying why. Your commitment to your religion of inductionism is really really deep.Absolute fail. Jesus was a liberal hippie

You have just made religion a form of induction.Accepting a theory because it has not yet been falsified is a form of induction. Jesus was a liberal hippie

Straggler writes:
Bare assertion, with no supporting evidence.
Epic fail. Again. Straggler writes:
I have not claimed to solve that "problem". It's a pseudo-problem. Science doesn't work that way at all.Hume identified this problem. Popper sought to solve it through his falsification thesis and is widely regarded as having failed. Apparently you have resolved it where they were unable to. Wiki on the problem of induction writes: 2. presupposing that a sequence of events in the future will occur as it always has in the past (for example, that the laws of physics will hold as they have always been observed to hold). Hume called this the Principle of Uniformity of Nature. The problem calls into question all empirical claims made in everyday life or through the scientific method. Although the problem arguably dates back to the Pyrrhonism of ancient philosophy, David Hume introduced it in the mid-18th century, with the most notable response provided by Karl Popper two centuries later. Either cite in detail your solution to this problem or just concede that you cannot. But thanks for clearly demonstrating that you haven't even been reading what I have been posting.

Modulous writes:
But I have.I think the 'problem' is describing science in such a way as to avoid using induction, and this is what people are saying you haven't really done in the 209 posts you've made here. When I do so, people could ask for further explanation. Instead, they assert (without evidence) that I am wrong, and then ask questions about potassium. Here's an example of what science actually does:
