Well, your "underdetermined" concept, when used as a catch-all for describing science, and when coupled by the claim that all the evidence counts equally for different hypotheses, would certainly add up to epistemic relativism...unless there's some clarification you would like to make.
What, again? This clearly escaped your notice:
Will Bouwman wrote: ↑Wed Nov 19, 2025 9:57 pmI am not applying underdetermination to all hypotheses, only to certain scientific and philosophical questions.
Okay. Say what sorts those are.
Immanuel Can wrote: ↑Wed Nov 19, 2025 10:22 pmScience is about differentiating hypotheses, based on the preponderance of evidence, and the most telling evidence.
Well, as I said in an article I wrote for Philosophy Now, science means different things to different people:
So do many words. But words also have meanings, common meanings, and legitimate meanings.
Will you list examples of 'those words' with 'common meanings', and 'legitimate meanings', and then write down what the 'common meanings', and 'legitimate meanings' are, exactly, and then inform the readers, here, what makes the 'legitimate meanings' 'legitimate', exactly?
If no, then why not?
What could possibly be stopping and preventing 'you' from informing 'the readers', here, of what 'you' consider to be what is true, right, accurate, and/or correct, in Life?

They're not just whatever somebody makes up.
Really?
If yes, then how did 'they' come to be, exactly?
What could be found, once more, here, is that the exact opposite of what "immanuel can" claimed, is the actual and irrefutable Truth, in Life.

They're used in communication, which always requires multiple understanders to arrive at the same sort of understanding. In that sense, theyr'e a kind of community property, not a free-for-all.
Okay. So, 'the meanings' of 'words' are, really, just what people make up.

With which of these three propositions do you most agree? A scientific theory must be:
(1) A logically coherent explanation.
(2) Supported by evidence.
(3) Useful.
If you are firmly of the opinion that one of these is the defining feature of science,
I'm not. And they're far from a complete list.
In fact, a theory might be all three. Some of the best ones are. But there are other virtues of scientific theories as well; they're called "epistemic virtues," and they include other qualities like "coherence," "consistency," "logical integrity," "objectivity," "replicability," and so on.
And, as always, 'they' are all more or less just 'assumptions' and/or 'guesses', only. Which means that 'they' all could be partly or absolutely fully False, Wrong, Inaccurate, and/or Incorrect. Which, again, leaves 'them' in the useless and/or waste of time and/or energy pile/s.
Again, especially considering 'the alternative', which is, again, readily available.
There is no wonder why 'these human beings' are taking so, so long, considering that 'they' obviously always choose 'one' over 'the other', here.

Bollocks. Clearly you will not listen to me so perhaps you will listen to the Stanford Encyclopaedia of Philosophy:
"At the heart of the underdetermination of scientific theory by evidence is the simple idea that the evidence available to us at a given time may be insufficient to determine what beliefs we should hold in response to it."
This does not imply what you think it does. It says that it is possible for there to be underdetermined theories, which nobody denies. It does not say that all theories, the best theories, or even most theories are of this kind.
Consequently, your claim about underdetermination is either trivial or untrue. Either it's so obvious that it adds no useful insight, or simply not reflective of most scientific theories.
Immanuel Can wrote: ↑Wed Nov 19, 2025 10:22 pmc) there are criteria for differentiating between the value of different theories.
Not always.
Very, very often...much more often than we run into underdetermined situations. Even Stanford says it only "may" happen.
Immanuel Can wrote: ↑Wed Nov 19, 2025 10:22 pmNot that it matters much to the present discussion, since Idealism isn't a reply to the infinite regress hypothesis, anyway.
Sorry mate, that is not what I am currently discussing.
Oh. Then we're done with Idealism.
Great.
See how, once again, "immanuel can" has introduced 'another red herring', and, again, 'tried to' use a straw man argument.
The lengths of 'deception' that "immanuel can" goes to, in this forum, is at the exact same level 'of deception' as 'the devil', itself.
Immanuel Can wrote: ↑Fri Nov 21, 2025 4:16 pm
I was only interested in the infinite regress problem.
Clearly.
And, you are so 'only interested' in that 'made up', but not able to be backed up and support so-called 'problem', you, still, have not been able to see, and understand, how 'that' is not even a 'problem', in and of itself, nor that 'it' has any actual bearing on any thing, here.
you only use 'that' because you have absolutely nothing else that could back up and support 'your belief', here. your Wrong, Inaccurate, and Incorrect interpretation of 'that so-called problem' is the only thing that you have left to use.
And, by the way, your hopes of 'that' helping and supporting you, here, are fading very fast, and fully.

Thanks for the chat.
