Then we are in complete agreement that the original claim in the
video, that the statement from the Islamists:
"...and how, uhm, *in the sea*, the *two waters*, they
don't mix. But they pass through each other"
is completely wrong! Then why are you posting and then defending the
video and the claims being made on it?
NOTE: This is an absolutist position that you are defending here.
"they don't mix" means just that - "a complete partition" (from the
Koran) means just that. Both the Koran and the Islamists treat fresh
water and salt water as two distinct compounds that *remain* distinct.

MAKE UP YOUR FREAKING MIND!!!!! Fresh water (one distinct type of
water) meets salt water (second distinct type of water) and remain
separate (IOW two distinct compounds that remain distinct) is directly
contradictory to your initial claim above, both on the issue of two
waters and mixing. Either it mixes or it doesn't - Either the two
types of water remain distinct or they don't You can't have it both
ways!
And what is your source for this claim as a rule? (BTW, citing the
Koran would produce nothing more than a circular argument) What is
your definition here of "remain separate"? It sounds like you are
trying to grasp for a major fudge factor that just isn't there.
There are indeed places in the oceans and estuaries where fresh water
and salt water meets up but they far more often than not DON'T remain
separate. If they do remain separate, as you insist on claiming
(minus your contrary initial statement above and your moving the
goalpost below), then what is the presumably separate source of
brackish water?
Read up on the flow of fresh water from the Amazon into the Atlantic
Ocean for a far more accurate account than what is reflected in the
Koran on what really goes on in nature.
The Amazon outflow represents 20% of the world's fresh water flowing
into the world's oceans. Yes, you can find drinkable water even with
no land in site. But when the details are more closely looked at,
even this most extreme outflow of fresh water in the world does not
support your absolutist position (OK, the position in the video and
the Koran - your position is hopelessly shifting).
What is found out to sea, near the mouth of the Amazon is a *dilution*
of salinity, not the absence of it. The further out you go, the more
salinity.
It is true that salt water is denser than fresh water so fresh water
has a *tendency* to override the salt water but this does not reflect
some sort of absolute barrier. Mixing does still occur. If it didn't
you would expect a distinct layer of freshwater over saltwater in the
world's oceans instead of a relatively quick increase in salinity as
you get further away from the mouth of a river that flows into the
ocean. There is no barrier at work here, at least not one that can
honestly be described as a "complete partition".
>2. It is totally irrelevant to argue that they are not two waters,
Except that the original video, and the Koran that you are defending,
both do make and/or reflect such a claim, a claim that in fact runs
contrary to what is actually observed in nature.
>or whether they mix at some other place or even if a tiny amount crosses
>the barrier or whether the barrier is natural or not etc
A TINY AMOUNT? Except for perhaps an underground cavern with uniquely
calm conditions we're talking about far more than that a tiny amount
of mixing. Do you even know the definition of the word barrier? What
is your definition of a "complete barrier"?
The claim that you are defending was that there is salt water and
there is fresh water and the two just don't mix due to some
unspecified barrier. In this particular post you are simultaneously
arguing both points, presumably because if you settle on one point or
the other you lose your overall argument that the Koran reflects the
actual current scientific view.
In short, you appear to be attempting to move the goalposts in light
of the fact that they do indeed mix in such a way that you can
continue to claim that they don't! Or at least to a degree that you
can attempt to salvage an underlying claim about the Koran.
And how is discussing whether or not they mix irrelevant to whether or
not there is a barrier. Remember, you are defending a book which
specifically claims the existence of a "complete barrier" between the
two
>3. This is a scientific fact and is mentioned in the Qur'an.
Nope! No such barrier - certainly not the "complete barrier" that the
Koran mistakenly points out.

What is so stupid about doing a direct experiment to test whether or
not salt water and fresh water mix or remain separate? Wouldn't you
want your hypothesis of an invisible (complete) barrier to be properly
vetted and proved? Or, in anticipation of the failure to support such
a hypothesis, would you instead claim that there are specific forces
in nature that just can't be tested?
>5. Ancient scripture is right. Modern day science worshiping professor

>Irony of ironies!!
Me thinks it isn't the good professor who is being proven ignorant
here.
Nowhere in the Qur'an does it say it is an absolute barrier and no
amount of water can pass through. That is your interpretation you want
to force so you can find fault. There is something that prevents the two
waters of different salinity to mix freely like would happen if two
glasses of waters were mixed.
Here are definitions from Wikipedia
Halocline
-------------
In oceanography, a halocline is cline caused by a strong, vertical
salinity gradient within a body of water. Because salinity (in concert
with temperature) affects the density of seawater, it can play a role in
its vertical stratification
Stratification
--------------------
Water stratification occurs when water masses with different properties
- salinity (halocline), oxygenation (chemocline), density (pycnocline),
temperature (thermocline) - form layers that act as barriers to water
mixing.
Did you read it? 'form layers that act as BARRIERS to water mixing'
What else is the Qur'an saying?
stop playing word games and admit the obvious. Dawkins had no idea of
this otherwise he wouldn't be foolish enough to propose a test of mixing
two glasses of water.
The author of Qur'an knew of this. Dawkins didn't. Why is it so
difficult to accept this?
"You have been given very little knowledge" Qur'an 17:85
First I want to commend you for returning to argue. Most
muslim propagandists on talk.origins are hit and run
posters.
But an obvious point that is made for comparable claims
about the bible is that nobody apparently understood this
verse (25:53 or 25:54, depending) before the discovery of
haloclines. In the case of the bible it is usually deemed
to be more fruitful to understand the text in a way that
would be meaningful for the early readers and I suggest we
do the same for the Quran. The two bodies of water can
fruitfully be interpreted as the fresh water (on land) and
the salt water as the seawater, and they do not mix insofar
as the sea won't become less salty nor the rivers more
salty. The "barrier" could just be a figure of speech.
But please leave the haloclines out of it. You would then
have to explain how the Quran knew about a rather peculiar
condition and was ignorant about the general case: that
rivers flowing into the sea mix with the seawater.

Your interpretation is very bad particularly when what actually happens
in some places can explain this perfectly. The verse states that 'He let
loose two bodies of water (or seas) .. yet he has made a barrier between
them, a partition that is forbidden to be passed. How could the last
sentence just be a figure of speech, also when the first part clearly
indicates they are free to mix?
As for your next question, what makes you think the author of the Qur'an
was ignorant of general case? It just wasn't remarkable enough.
The only explanation a non believer can come up with is that this
phenomenon was known at that time so was mentioned in the Qur'an
although there doesn't seem to be any evidence of this.
But still my point remains that the author of Qur'an knew something that
Mr. Dawkins was ignorant of.
I get a bit confused by your self-contradictory explanations,
which are therefore hard to accept as explanations at all.
First you have now explained that the Quran shows that the
two bodies of mater are free to mix (an interpretation for
the first part of the verse I do not accept: letting loose
does not imply mixing, unless you want to perpretrate the
horror of special pleading: "but there it does"), then you
explain that this (the general case) is so unremarkable that
the Quran does not mention it. This is a good time to ask
you how this verse was interpreted before the discovery of
haloclines. We must assume: wrongly. But this then means that
we basically do not understand anything in the Quran, as a
discovery tomorrow or centuries later will show that only
under that aspect can any specific part of the Quran be
understood. Yes, even the "halocline interpretation" of
Qur 25:53 could get superseded by a new discovery.
Really, my insistance that the Quran (or the bible) be
interpreted in a way that is meaningful for all readers
through time just tries to avoid such absurdities.
You also quote the Quran on an impassable barrier
("forbidden to be passed. The mind boggles, as mixing
occurs along a halocline. In an earlier reply you seemed
to have acknowledged this. You have now the choice to be
consistent one way or the other and either deny that
mixing occurs along a halocline, denying science, or
accept that mixing occurs along a halocline, and therefore
that the Quran is incorrect about an impassable barrier.
Isn't this again a reason to leave haloclines out of this
dicussion, if only to be able to embrace both science and
the Quran?
Regards,
Karel
Wrong. They do mix.
The point is that if you have a steady supply of fresh water, you get
a gradient of salt concentration near the region where it meets salty
water.
Normally they mix turbulently, so there is no clear boundary between
the two, but in exceptionally calm waters, if fresh water enters from
above, the salt concentration gradient may become step, resulting in
an apparent visible boundary surface due to different refraction
indexes.
But that apparent boundary is no barrier: fresh water from above
continually crosses it just to be replaced by new fresh water.
Shut down the fresh water supply and the gradient will eventually
disappear.

You can reproduce the halocline even in the lab or at home, if you
manage to put toghether salty water and fresh water without causing
much turbolence. But the point stands: they eventually do mix.

There is no contradiction. You just want to see things in black and white.

If one reads the whole verse it does mean that. The fact that both
bodies of water are free to move yet remain separate is a sign of Allah.
That is the most natural interpretation. YOU have to bring evidence to
prove 'barrier' is just used in figurative sense.

Any previous interpretation would only be authoritative if it came from
the Prophet (pbuh) himself but there are none for such verses (usuallY)
that talk about physical world. He left such verses to be pondered on by
people so if the people of the 8th or 9th century explained them
according to their knowledge it is not at all binding on Muslims to
stick to that interpretation.

No. The part of Qur'an necessary for guidance (commandments, rules etc)
has been explained by the Prophet (pbuh) and is known as the Sunnah. But
other verses can reveal new meanings as our knowledge grows. The belief
that Qur'an contains ancient historical knowledge as well as modern is
very old. It is based on the belief that the Qur'an is the word of God
who knows all. You cannot demand that Muslims start from the assumption
that the Qur'an was written by ordinary human beings and thus reject any
interpretation that indicates divine knowledge by its author even if it
is a much better one.
> Yes, even the "halocline interpretation" of
> Qur 25:53 could get superseded by a new discovery.
Yes. if the new meaning fits the words of the Qur'an better. Isn't that
how Science works! Any new theory that explains the facts/signs in a
better way is accepted. This holds true for the ayahs (signs/verses) of
the Qur'an as well.
> Really, my insistance that the Quran (or the bible) be
> interpreted in a way that is meaningful for all readers
> through time just tries to avoid such absurdities.
But why do you want to limit it to one meaning? It is an established
belief among Muslim scholars that verses of Qur'an have multiple
meanings. That there are layers of meanings, some subtle and others not
so subtle.
So, the earlier Muslims could interpret it as you have suggested and now
with the discovery of haloclines a much clearer and better
interpretation can be arrived at.

But there is not much of a mixing even if it happens, otherwise no one
would have called it a barrier. The video also clearly showed that the
man was entering one type of water to another (which appeared to be air)
So the bulk of water was prevented to pass (forbidden to pass). Just
like in a balloon, air trapped inside is forbidden to pass through,
though strictly speaking, hundreds of thousands of molecules would still
be crossing!

Now who is arguing semantics. The video that you are defending here
quotes the Koran as stating:
"... and He has set a barrier and a complete partition
between them"
In the same video that you are defending, it was the Islamists who
stated:
"...and how, uhm, *in the sea*, the *two waters*, they
don't mix. But they pass through each other"
So, when I used the verbiage "absolute barrier" I was describing what
the Koran called a "complete partition" that, it is being alleged
here, prevents any mixing of fresh and salt water.
How is that not an absolute barrier? What part of "they don't mix"
(from the Islamists you are defending here) don't you understand?
Again, it is you who seems to be equivocating here in order to try
and have it both ways. As far as passing through, my argument here
only concerns the bogus claim that they don't mix as they do so.
That said, it is the Koran, that you are defending here, which claims
that there is a "complete partition between them" so that is an
apparent contradiction that you may have to explain, not me.
I readily admit that different bodies of waters do "pass through" each
other, but they do mix together, to one degree or another, as they do
so - depending upon various conditions at hand.
>That is your interpretation you want
>to force so you can find fault. There is something that prevents the two
>waters of different salinity to mix freely like would happen if two
>glasses of waters were mixed.
BUT MIXING IS PRECISELY WHAT IS OBSERVED IN NATURE!!!!
And, again, with what appears to be equivocating. First you defend an
absolute position of no mixing (watch the video - read the Koran!!!),
then you try and shift the definition to include "mix freely".
IT MIXES. Get over it!!! The mere act of a body of fresh water
*flowing into* a body of salt water clearly contributes to such
mixing. How else do we get brackish water? (a question repeatedly
posed, which you continue to dodge)
BTW, there is a difference between the two phrases "prevents the two
from mixing" and "prevents the two from mixing *freely*" These are
two distinct concepts - PICK ONE AND STICK TO IT!!!!
(If you pick the second one it will give you far more weasel room even
if it does contradict the Koran's claim of a "complete partition" and
the Islamists claim of no mixing)

Yes, and note the not the least bit trivial term "salinity gradient"
with respect to the issues actually being discussed here.
There is a world of a difference between a salinity gradient and some
sort of absolute barrier, excuse me, I mean "complete partition".
And this is all in support of the observed fact that, with few unique
exceptions, salinity varies at different ocean depths and that is a
completely different concept than the claim that you are defending
here (when you are not equivocating) that they don't mix, that fresh
water somehow magically remains separate and fresh. (It doesn't -
they mix - exactly how readily may be open to discussion, but they
still mix)

Act as "barriers" to a degree, yes, but not to a degree that would
support the Koran's claim of a "complete partition" or the claim made
by the Islamists in the video that "the two waters, they don't mix".
And also note that the Islamists that you are defending here also
claimed:
"the *two waters*, they don't mix. But they pass
through each other"
So how does this work in conjunction with stratification? Do the
waters really "pass through each other" *without mixing* or is this
just one more layer of bullshit piled on top of bullshit?
We're not talking about oil and water here. We do not find separate
and distinct pools of each in nature nor should we expect to (except,
I suppose, those who are simply told as much by the Koran). What we
do find is different gradients (as even you noted above) of salinity,
where there is clearly NO BARRIER and MIXING DOES OCCUR.
>Did you read it? 'form layers that act as BARRIERS to water mixing'
Read on and it also states:
"Stratification may be upset by turbulence. This creates
mixed layers of water."
Remember, we are talking about fresh water being introduced to salt
water, where the fresh water has a *tendency* to override the salt
water (with increasing salinity as we get further out - as the two
M-I-X). Furthermore, there is typically plenty of turbulence at the
surface, particularly with wave action, that no doubt contributes to
the mixing.
But more to the point, in nature it is both readily and repeatedly
observed that THEY DO MIX!!!!!
>What else is the Qur'an saying?
Who the hell cares? We should be talking about what nature is showing
us - what the actual empirical evidence is saying as opposed to
getting stuck up on some 7th century holy book.
>stop playing word games and admit the obvious. Dawkins had no idea of

His proposed experiment was both simple and directly to the point. It
would have clearly shown that salt water and fresh water *can* indeed
mix and that there is no hidden barrier that *prevents* the two from
mixing, either completely or with a variety of differing salinities.
If one chose to carefully add fresh water to a container already
containing salt water one could also demonstrate that stratification
*can* occur, at least under the most pristine condition. And then any
number of methods can be used to demonstrate that they CAN MIX as
well, just as THEY DO in nature.
>The author of Qur'an knew of this. Dawkins didn't. Why is it so
>difficult to accept this?
Knew what exactly? That salt water and fresh water don't mix? That
there is some sort of "complete partitions" that prevents this from
happening?
Both the experiment that Dawkins proposed and what we readily and
repeatedly observe in nature clearly show us that THEY INDEED DO MIX
and that THERE IS NO SUCH BARRIER as you continue to propose, complete
with your repeated weasely equivocations made necessary due to the
FACT that your holy book directly contradicts what is ACTUALLY
OBSERVED in nature.
Dawkins was right - salt water and fresh water do mix - no absolute
barrier here - The Koran is wrong on this point - get over it.
>"You have been given very little knowledge" Qur'an 17:85

Typical arrogant religious fundie. My holy book tells me that I am
smarter than you so I am under no obligation to pull my head out of my
ass and actually see the world as it is and - God Forbid - become
better informed because my holy book is telling me that I already know
everything that I need to.

The easiest way to demonstrate the effectt is by adding sugar to a glass of hot
water and then let a teabag float on top. You will sea a clear region at the
bottom, containing a sugar solution and the tea on top of that.
It takes 10 minutes and provides a cup of tea _and_ some insight.

Very well. If you want to insist that impassable means
passable and that passable means impassable and that
therefore the Quran is right, you are welcome.
I summarize my position:
Qur 25:53 describes a general situation. This is clearest
when one starts reading in 48. The sweet water is the water
that falls from heaven (and fills lakes and rivers). The
text (53 and surrounding verses) gives no indication that
it addresses an exceptional condition. That is just your
addition to the text. Add what you want, but do not expect
me to accept it.
Even when we accept that this verse refers to an exception
(I don't), the text only conforms to science when we
change absolute words to relative words. Feel free to change
them, but do not hope to convince me that way. Am I really
to understand that the Quran cannot speak about a scientific
observation with exactness?

It is sometimes hard to decide what is worse, bogus prophesies or bad
apologetics.
In this case, the first video defends a falsehood by defending the
voracity of the claim while the second video defends the original
source, the Koran, by distorting the original claim so that it can be
made to appear as though the source remains consistent with reality.
One attempts to change our view of reality to match the Koran while
the other attempts to bend the Koran to reality. Neither ends up
being an honest endeavor.
It's fun to sometimes watch the gymnastics though.
Thank you. That confirms the line my thoughts were taking
and is a much less forced interpretation than the haloclines.

What reality? That there is an insurmountable barrier in the form of

how does it not? Clearly the fresh water remains separate from the salt
water so it is available for drinking. This indicates a barrier in that
area.
I'm confused. What has this to do with your original video, or the
references to haloclines and submarine freshwater springs?
I'm further confused. I thought that you were rejecting the Maulana
Muhammad Ali's interpretation. And the land is not an insurmountable
barrier - freshwater flows along rivers and aquifers to the sea where it
mixes with sea water. And in most areas of interior drainage (Lake Chad
seems to be an exception - much of its inflow drains into aquifers
rather than being lost to evaporation) the rivers end in saline lakes.

The freshwater doesn't remain separate from the sea water. It rises from
springs, and turbulently mixes with sea water. That it doesn't
completely mix instantaneously does not validate claims of impassible
barriers.

Cave divers often run into exactly the mix you say doesn't exist. It's
called the "halocline." While it is often thought of as two distinct
types, it is actually simply a degree of salinity. Freshwater can
readily become saltwater, and likewise saltwater can easily become
freshwater. There is no barrier, they mix all the time.

Exactly. So why say this (or any similar) interpretation is correct
because there is an insurmountable/absolute barrier in the form of land
when actually there is none??
Muhammad Ali and other older scholars only settled with this because
they weren't aware of haloclines or fresh water springs.

The government that governs least governs best.
Isn't the other problem with J's argument (That the koran has an
accurate description of a natural process that was IMMPOSSIBLE for a
mere mortal at the time to know) that, surely, people who live in the
arabian deserts along the Red Sea and had to dig, often quite deep, to
obtain fresh water, understood ALREADY that fresh water could rest
ontop of salt water, ESPECIALLY in still aquifers? It seems like
something the average Arab of Mo's time would've encountered
frequently, arguably more so than, say, europeans, because often in
the gulf salty marine water is able to infiltrate ground water
deposits (and thus co-occur more frequently than in some other
places)?
So J's arguement seems to be wrong because:
1. The barrier is non existent, it is not a barrier, the waters can
and do mix
2. The halocline is a density dependant feature, and if Mo understood
it he'd be referencing density and bouyancy
3. The arab's must've seen fresh atop salt water quite often (hell
that's probably why its called 'sweet', because its potable water
they've encountered in wells) so its not any kind of special
knowledge.
Mo was most likely making an allegorical reference to a common
observation in order to describe a theological process. And use of
allegories is quite common in the Jewish and Christian religious
tradition, of which Islam was developed in.
