Quoted message said:Quoted message said:KA:- There are no absolute assumptions in science.
Quoted message said:Quoted message said:JE:- Firstly, an absolute assumption is NOT the same concept of a supposed, known absolute.
Quoted message said:KA:- There are no known physical absolutes.
JE:- Wow! KA knows everything in the entire universe.
KA:-
Quoted message said:snip<
I know that there is no absolute proof to any physical aspect of the universe, other than, possibly,
the fact that *I* exists.
JE:- Ah, the royal "I" using a plural "exists" ;-)
"I think therefore I am is a self consistent _assumption_ so it is valid, that is all.
Quoted message said:KA:- Hint: Special relativity pointed the way to the way the rest of the universe worked.
Quoted message said:JE:- So the speed of light is not absolutely maximised at c, so WE CAN go faster than c?
KA:- Not at issue. It is an assumption of a model that makes correct predictions. It is also
possible to dispense with this assumption, in addition to the assumption of relative motion and
produce a theory that also makes correct predictions. This theory is named the Lorentz Ether Theory
(LET). It is mathematically identical to Special Relativity, and can not be experimentally
distinguished from it. It is based on an absolute space assumption (non relative motion) and a
variable speed of light, that is measured incorrectly due to distortions of length.
JE:- All you did was refute your view that an absolute assumption need not exist. You simply
replaced one absolute assumption with another!
Quoted message said:snip nonsense<
Quoted message said:Quoted message said:KA:- We do not know and cannot know if a known absolute exists but we must assume an absolute
ASSUMPTION
Quoted message said:KA:- No. We only have to pretend.
Quoted message said:JE:- An assumption is just a PRETENCE?
KA:- Yes. Of course. You are obviously clueless on simple physics.
JE:- Do you also have to pretend that you were only pretending (!) or do you, SOMEWHERE, have to say
something ABSOLUTELY POSITIVE to avoid entering the black hole of Epimenides paradox?
Quoted message said:JE:- I suggest you have a negative personality disorder.
KA:- This is completely irrelevant to the issue at hand.
JE:- Really? You don't think your warped perspective for the negative may be creating a bias against
POSITIVE absolute assumptions?
Quoted message said:JE:- You have to employ at least one absolute assumption.
KA:- You have to make an assumption as a starting point. Something, for the sake of argument that
you take to be true in a relative sense.
JE:- NO, that you take to be true in an ABSOLUTE sense, where this is an ABOLUTE ASSUMPTION and NOT
A KNOWN ABSOLUTE.
KA:- It is not assumed in science that such an assumption is absolutely true.
JE:- Science simply demands it be testable. Only politics within science cares what it actually
means! For science all testable absolute assumptions are equal. They all must be tested without
bias. You can like one more than another, testing the ones you don't like before any others to try
to refute them, but you cannot allow any bias while testing and you cannot evade testing the ideas
you like to refutation.
KA:- It is just a model.
JE:- No. A theory is NOT A MODEL. A model is just a valid simplification of a theory. Models are
created to help test the theory they were simplified from.
KA:- That is, all else is derived from that assumption.
JE:- As I said, an absolute assumption is only testable via the _finite_ set of deductions
it allows.
Quoted message said:snip<
Quoted message said:JE:- This can be just imagined or be an observed maximum/constant found within nature. After you
have done this you attach variables to it. The way the variables are attached alters the theory
structure. When you have achieved a theory structure that is not contradictory then valid
deductions become possible from that theory. These deductions allow you to test the proposition
against nature.
KA:- But it doesn't show that the assumptions were absolutely true. Descriptions of the universe are
non unique.
JE:- Nobody in science knows (or cares) if absolute assumptions are true or not, that is the point!
All they care about is: are they testable? If the abolute assumptions that are the keystone of any
theory are actually different and not just semantically different, then each theory will have a
unique set of deductions. This means that certain verifications will be unique to each theory. These
unique verifications are much more important than any common verifications that may exist between
them because they separate each theory. However points of refutation must exist for each theory, as
well. This means no anti-thesis deductions are allowed to be observed within nature. If they are,
the theory they are an anti thesis of, stands refuted. OK?
Quoted message said:Quoted message said:JE :- (a guess) to make ANY view testable. OK?
Quoted message said:KA:- No, we don't make absolute assumptions in science. We make assumptions. Period.
Quoted message said:JE:- Mad Hatter nonsense.
KA:- Personal insults make for a poor argument.
JE:- No, they "make for a poor argument" if they are not accompanied by any valid argument. This was
NOT the case here. Such rhetoric can accompany an argument for emotional emphasis, especially within
less formal discussion, like sbe.
Quoted message said:KA:- Assumptions can be absolute
Quoted message said:selection exists within a model is an absolute assumption because it is the total deletion
KA:- Not at all. Its an assumption for that particular model, different models, predicting the same
results might use different assumptions.
JE:- The point under discussion was: "we don't make absolute assumptions in science. We make
assumptions. Period." The fact that different models make different types of assumption i.e.
relative and absolute, refutes your proposition it does not verify it. ASSUMPTIONS ARE EITHER
ABSOLUTE OR RELATIVE. If you disagree provide any view of science that does not have both an
absolute and relative assumption.

________________________________________________________
You have contradicted yourself, ABSOLUTELY, above.
KA:- Wow...aren't you clever.
JE:- wow...aren't you stupid.
KA:- Personal insults make for a poor argument.
JE:- Yes, but you insulted me. firstly. Note that a zero argument is even worse than just an
empty insult...
Quoted message said:JE:- (you asked for it so you got it)
KA:- So you consider losing technical arguments are a justification to hurl personal insults as a
last resort?
JE:- You lost the argument. Period. You refused to amend your self contradictory view that "nothing
is absolute", to "no positive absolute exists". You have to do this because "nothing is absolute" IS
an absolute negative assumption. Got it?
Quoted message said:KA:- Look, I'm not concerned with one off technicalities. I am referring the basics of *real*
science. Science never claims absolutes.
Quoted message said:JE:- "Technicalities"? So you condone witch burning because of the fact that the absolute
assumption of what a witch was supposed to be could not be tested where this deficiency is just a
"technicality?".
KA:- Not relevant in the slightest. This has nothing to do with *science*,
e.g. Physics.
JE:- Only physics is SCIENCE? What nonsane. Why do you bother to subscribe to sbe?
KA:- This is about ignorant peasants with no idea of the *scientific method*, ..
JE:- You have been shown to be one of them.
Quoted message said:snip<
Quoted message said:KA:- Perhaps it would suddenly become a non technicality if you were the accused witch....
KA:- I am not discussing the views of peasants, I am discussing the views of modern science.
JE:- This means "I refuse to discuss any view that refutes my position".
Quoted message said:KA:- Is it also just a "technicality" that Epimenides paradox is an absolute self contradiction?
KA:- This has nothing to do with real science. Its simply a conversation maker for those who are
unable to do real science.
JE:- Dear or dear... So, "real science" allows an absolute self contradiction?

Quoted message said:JE:- "Reality"? Your version of reality is absolute

James Burke writes, in the 1985 PBS series, The Day The Universe Changed [p 337] "The search for the
truth, the 'discovery of nature's secrets,’ as Descartes put it, is an idiosyncratic search for
temporary truth. One truth is replaced by another.
Quoted message said:snip<
JE:- Yes, one absolute assumption is replaced by another after a testable view is refuted. If you
cannot refute the view then truth in science cannot evolve in this way.
Quoted message said:KA:- AND NOT MINE since it is absolutely _anything_ that you say it is because it does not have to
be testable. Do you know what Epimenides paradox is? Do you know what a travesty of intellectual
thought any absolute self contradiction is??
KA:_ You are not discussing science. You are pissing about with words in an effort to obscure your
lack of knowledge on the core subject matter, that is about Science.
JE:- Yes for you, epistemology is only "pissing about with words"..
In case you are not aware of it this is NOT just a discussion about A SCIENCE it is a discussion
that concerns the epistemology of ANY science. You appear to know nothing, or have zero respect for,
the epistemology of science. You are not alone here, so don't feel bad about it ;-)
_________________________________________
This discussion with KA is a waste of time because KA does not know anything, and does not care to
learn anything, about the epistemology of science, THE SUBJECT OF THIS DISCUSSION.
