Let me address the entirety of your argument in one go, disjointed
scattershot rebuttals that do not tie things back to a central premise
or point drive arguments off the rails by introducing exponential
numbers of points as the replies proceed.
Of course physical quantity is objective:
You have five fingers on one hand: the word/number is a description of a physical state
Quantities are not states of matter. The concept of describing the flesh which protrudes from your limbs as "five" fingers or "five toes" is an abstract.
one that can be objectively determined independently by all observers
If it is indeed "objectively determined independently by all observers" then how is it rationalized? How does one control for that which is independent if it's in fact independent?
So in this respect physical quantity refers to the objective differences
between distinct objective physical states - and is thus objective.
Once again, quantities are not physical states. If you intend on levying a contention, then answer my previous question: what is the mass, volume, and chemical composition of the number, two? Or any number for that matter?
If numbers and physical quantities weren’t objective, then we could
change the logic of maths change numbers arbitrarily on a whim if we do
chose
The standard can be changed if a consistent logic is sustained. That does not make it arbitrary; that does not make it whimsical.
(this is exactly what you’re argument implies and, even were it not - would be a straw man not a non-sequitur FYI).
First, a non-sequitur is a faulty conclusion derived from a misinterpretation or misrepresentation of a premise. A strawman argument is a claim of refutation by misrepresenting one's opponent's argument. So for your information, it is in fact a non sequitur.
I can also convey the new meaning of 11 to someone else; because it is
objectively reference to something outside my mind; and has that to
validate any maths I use.
How are you able to control for your experience outside of your mind?
As these are objective, I could say 1 + 11 = 6;
You are only interchanging the names and symbols of the numbers. That does not inform your point on objectivity.
if you knew the physical
quantities I was referring to;
The perception of which is informed by the bias of one's experience.
you could derive that relationship by
placing stones - because it’s based on the real world.
The real world is informed by the bias of one's mind.
It’s that anchoring, and the derivation from external things that allows
you to determine that if is objective: “not dependent on the mind for
existence; actual”.
Once again, and this is the crux of our discussion: how does one control for one's mind as it concerns the presumption of the "external"? Can you shut your mind off and still perceive, experience, learn and observe? If you assume, yes, then explain how.
As I showed, by placing stones, you can demonstrate the relationship
between 1, 5 and 6 using the real world; but cannot do so with your
example of colour. That demonstrates the difference between an objective
and subjective conclusion.
You have demonstrating nothing other than your abstracts and how perceive them being fixed. That is not objectivity.
I explained this by showing you need not use numbers, but can use
physical objects in their place - I will note you did not challenge
this; but instead implied that because I didn’t do so in the following
sentence, I can’t.
That’s a particularly poor argument; as if
let’s you suggest I can’t represent 2 or 6 with physical items without
actually explicitly stating it and looking silly if I did (number of
feet, number of protons in a carbon atom.)
Yes, I've challenged this by asking you to provide the physical properties (i.e. mass, volume, and chemical compositions) of said numbers, particularly the number two. You have yet to do this. You can choose any number you want.
I find this is a common argumentative tactic: to bury a fallacy deep in layers of abstraction in order to obfuscate where it is.
Identify and explicitly state the fallacy deep in layers of abstraction which obfuscates.
So to prevent equivocation; I can be more explicit, by clarifying
exactly what objective means in P1 based upon why an objective basis
makes science valid: what about objective things is it that drives the
validity of science.
So let’s skip explicit definitions and approach the issue functionally.
We
all have to start with two basic assumptions - that we’re all
experiencing the same reality and that reasoning about that reality is
valid.
This is to say that we’re both here talking to each other
and basic stuff like true != false. Without making those two
assumptions, there is no basis to have a conversation about anything; so
they’re pretty fair.
Making these assumptions : To determine
what is true - to make true claims about realty, we need the ability to
correctly analyze reality as it is, without error.
If our inputs and quality of processing has errors - we cannot rely on the output to be true.
So to get at the truth, we have to ensure that we have removed error from our inputs and processing.
Because
we can only calibrate ourselves using ourselves - we can’t really ever
determine what is true, we can only tell what is true having nominally
ruled out specific errors.
The more errors you can rule out, the more confident that your output is true.
This brings us back to science - and “objectivity” that we’re talking about.
Science
of all forms is at its simplest a way we have figured out for
eliminating as many errors as we can from our thinking and our
interpretation of reality to derive an accurate description of reality.
The
inputs have to come from reality, the output has to be consistent with
the inputs and itself. If a measurement contradicts the output, or there
is an inconsistency; we can presume an error has occurred and needs to
be tracked down. The error may be solved, or may cause the output to be
discarded.
We apply Occam’s razor - limiting assumptions in order
to minimize points of failure and number of places we could be wrong
(more assumptions - more potential of being wrong)
We experiment -
we use the output to predict inputs we haven’t seen, and to confirm
inputs match what is expected. This is probably the most important - an
explanation may require additional things to be true or false; if we
find this is truly the case it’s more likely to be because the
explanation is accurate rather than coincidentally correct.
If we
cannot find and way to check whether the output is true or false; we
discard it - as we can’t tell whether it is in error or not.
We
can even validate whether the process works; the process allows us to
exploit the world; split the atom, cure illness, etc; that our
descriptions of the world lead to practical application raise confidence
in the accuracy of those descriptions. Why should a pressurized water
reactor work so consistently if the description of the physics is
incorrect?
But, a big element of where we remove error; is by
using objective information; or to be more specific - information that
can be independently derived and validated from external things, without
depending on our mind.
People lie, people are mistaken, people
are deluded, mislead, etc - the source of input data cannot come from
someone’s mind and be assumed to be without error. If we cannot tie
inputs to reality, it cannot be expected that the output reflects
reality.
How does any of this reside outside of the bias of one's mind, including one's notion of reality?
Is the observation real, a fluke, or a delusion: the best way to have
confidence in that is to have multiple people observing it; or agree on
what is being observed.
We have to agree on meaning - what is a meter, what is a second, a gram,
what is 5: (which is the error in your last argument, I can no more
tell you how much 5 weighs than I can tell you how many meters a second
is; they’re all descriptions of different things).
Consensus = consensus. Consensus =/= objectivity.
So in this respect, even though you’re clearly wrong in your
interpretation of what is objective and not; even were we to accept your
implicit interpretation, it doesn’t even matter; as all the things
we’re talking about clearly meet the functional requirements to minimize
error and improve confidence in conclusions by removing our brain as an
input - the reason these things are used to produce valid results.
No, I'm not. All you've conveyed is your evaluation of your perception (i.e. subjective.) Hence, you've informed my point.
