The fact remains that we have evidence that intelligent agents can produce information.

The operative phrase is "can produce". You can't infer that all information comes from intelligent sources any more than you can infer that all saliva comes from George W. Bush.

Quote:
The more complex the information, the less probability that nature can produce it.

First, a probability claim without probability calculations is worthless.

Second, it doesn't matter how small the probability is of nature producing complex information. If there is any non-zero probability, it will happen, given enough time.

Quote:
And that was the idea behind Darwins theory; we started small and relatively simple.

No, that wasn't the idea behind Darwin's theory. Darwin's idea was to explain the differences between species of similar complexity.

No, it isn't. To a first approximation "meaning" is what you have in mind, whereas a definition is limited to what can be expressed in words.

And that is because the 18th century philosophers like David Hume (who were ironically called empiricists) changed the meaning of the word to accomodate a particular philosophical bias.
I doubt that philosophers had much influence on the meaning of "science".

Rob wrote:
If the meaning of words comes from the way people use them, then how do we decide who's meaning is valid?
Meaning is inherently subjective. There is no determining who is right and who is wrong. People argue over meanings all the time.

If you want to discuss language, and how it works, that's a different topic so should be in a separate thread.

It seems to me that the way people actually reason is what "defines" what reason is. And often logic is not involved. Oh, by the way, when I denied that there are laws of reason, I was not saying anything about laws of logic.

Wiki wrote:
The laws of thought are fundamental logical rules, with a long tradition in the history of philosophy, which collectively prescribe how a rational mind must think. To break any of the laws of thought (for example, to contradict oneself) is to be irrational.
You failed to give the url, so I don't know where you found that. In any case, I don't take Wiki to be the final arbiter. There are no laws of thought, though George Boole used "Laws of Thought" in the title for his book on Boolean algebra. And sure, there are plenty of philosophers who mistakenly believe that thought is logic. But then philosophy has an unbroken 2000 year record of failure in its attempts to explain thought.

Rob wrote:

Philosophy (like natural science) is applied logic (specifically the law of contradiction).
I don't attempt to define philosophy. Natural science is not applied logic, though it does apply logic.

As far as I know, SETI is searching for "interesting" signals from outer space. As far as I know, there is no commitment to declaring an interesting signal to be information, and there is no commitment to declaring that an interesting signal had an intelligent origin.

I assume (but do not have a citation to offer at this time), that the additional investigation would be to determine whether the signal contains information.
Don't assume. Find out. Most of the nonsense you post comes from making wrong assumptions.

Incidentally, I am not a proponent of the SETI program, and further discussion of SETI would only take us further off topic.

A compact disk is not information, either. The information is represented on the CD, but is not the CD. That's the abstractness property that I expect of information. But we don't find that with DNA. Rather, we find that the DNA is part of a causal mechanism.

Let me mention John Wilkins. He is a philosopher of science - actually a philosopher of biology. He has an interesting blog named Evolving Thoughts. He also argues that DNA is not information, and for somewhat similar reasons. I suggest you search his blog - you will probably find a discussion of John's ideas on information.

Inductive reasoning such as "all known information is produced by intelligence, therefore all information has an intelligent cause" are what we call theories.
I am not aware of any scientific theory that is of the form of a simple induction. It is alleged by some philosophers that theories arise from induction, but I don't know of any claims that a theory arises in such a simplistic was as your example.

In the case of information, I shall assume we are talking about Shannon information which comes from Shannon's theory of information. The theory was presented in a 1948 paper in the Bell System Technical Journal, entitled "A Mathematical Theory of Communications." There is also a 1949 book by Shannon and Weaver, with title "The Mathematical Theory of Communication" and that might be easier to find.

Generally in science, when we make deductions, our starting premises are the definitions of the terms used and data from measurements or observations. Since "is produced by intelligence" is not part of Shannon's definition, it isn't anything that is going to come up in such deductions, though it could be part of the informal discussion related to the theory. Shannon does describe typical cases, such as where a human is involved in generating the information. But there is no reliance on that, except as an illustrative example.

The definitions are all related how information is encoded and communicated. Exactly what counts as information might be ambiguous (my claim that DNA is not information, for example), because the theory doesn't try to define what is information. Anything that is used in the way that the theory describes could be treated as if information.

In the cases where the theory is used, there isn't much disagreement. Cases (such as DNA) where there is disagreement occur when we don't actually have much use for Shannon's theory. So you are using "information" in ways not intended by Shannon, and not addressed by his theory. The type of inference you want to make is not licensed by any science that I know.

Incidently, the water meter in my basement sends information to an external device, so that the city water department can read the meter without having to enter the house. And the water meter sure doesn't look intelligent to me.

The water meter was created by intelligent agents for the express purpose of conveying information.

The meter is not a natural phenomenon. It doesn't produce information except that it was designed to do so.

There is your basic problem.

If you want a strict definition of information, then DNA isn't information.

If you want a loose definition of information, then there are natural sources of information.

Either way, there is no support for the kind of inference you want to make.

Since you don't trust Wiki all of a sudden, I'll quote them and then Discover magazine.

Wiki wrote:
This article is about the field of philosophy. For the album by Borknagar, see Empiricism (album).

In philosophy generally, empiricism is an epistemological concept, or a theory of knowledge, emphasizing the role of experience and evidence, especially sensory perception, in the formation of ideas, while discounting the notion of innate ideas.

In the philosophy of science, empiricism is a theory of knowledge which emphasizes those aspects of scientific knowledge that are closely related to evidence, especially as formed through deliberate experimental arrangements. It is a fundamental requirement of scientific method that all hypotheses and theories must be tested against observations of the natural world, rather than resting solely on a priori reasoning, intuition, or revelation. Hence, science is considered to be methodologically empirical in nature...

...Some important philosophers commonly associated with empiricism include Francis Bacon, Thomas Hobbes, John Locke, George Berkeley, David Hume, John Stuart Mill, Gilles Deleuze and Felix Guattari.
( http://en.wikipedia.org/wiki/Empiricists )

Discover Magazine wrote:
Expert testimony reveals that since the scientific revolution of the 16th and 17th centuries, science has been limited to the search for natural causes to explain natural phenomena. This revolution entailed the rejection of the appeal to authority, and by extension, revelation, in favor of empirical evidence. Since that time period, science has been a discipline in which testability, rather than any ecclesiastical authority or philosophical coherence, has been the measure of a scientific idea's worth. In deliberately omitting theological or "ultimate" explanations for the existence or characteristics of the natural world, science does not consider issues of "meaning" and "purpose" in the world. While supernatural explanations may be important and have merit, they are not part of science. This self-imposed convention of science, which limits inquiry to testable, natural explanations about the natural world, is referred to by philosophers as "methodological naturalism" and is sometimes known as the scientific method. Methodological naturalism is a "ground rule" of science today which requires scientists to seek explanations in the world around us based upon what we can observe, test, replicate, and verify.

Well I can appriciate your skepticism, but it is a fact of history. Many of us were decieved by these philosophers, including myself. Now that you have factual reason to turn your skepticism on the philosophy of naturalism, you can research it some more for yourself. But if you want naturalism to be true for existential reasons, then you are free to forget everything I am saying.

Empiricism (naturalism)is not science and philosophy. It is only one attempt to engage in philosophy and science. The most scientific (or logically philosophical) interpretation, is the one that proves to be the most logical, i.e. coherent, i.e. consistent theory. That is if you are interested in being logical. You appear to be more motivated by emotion and the existential desire for the conclusion to be predetermed to deny divinity.

One of the most defining and notable figures of that time was the philosopher David Hume. Let's apply the skeptical lens to him for a moment.

David Hume wrote:
"When we run over libraries, persuaded of these principles, what havoc must we make? If we take in our hand any volume of divinity or school metaphysics, for instance, let us ask, ‘Does it contain any abstract reasoning concerning quantity or number’? No. ‘Does it contain any experimental reasoning concerning matter of fact and existence’? No. Commit it then to the flames, for it can contain nothing but sophistry and illusion."
( David Hume / An Inquiry Concerning Human Understanding / sec. XII, pt 3 )

Ravi Zacharius explains that Hume’s logic is fatally flawed because his own statement does not contain any abstract reasoning concerning quantity or number. Nor does it contain any experimental reasoning concerning matter of fact and existence. The empiricists like David Hume missed something vital. And the best way to see the illusion is to ask the question Dr. Zacharius asked when faced with Hume’s remarks. He asked, “How do we make a meaningful statement that is metaphysically stated, in order to tell us that metaphysics is meaningless”?

In case you had trouble with that, I’ll put it another way. ‘How do we propose a philosophy that says that philosophy is meaningless?’ It’s like saying, ‘English is unintelligible’, or ‘words do not have any meaning’. Fascinating! It takes a spirit to deny spirit. It takes an intellect to deny intellect. And that is what we should expect, since the empirical world does not deny intellect. If anything, the rocks cry out that, ‘God is not mocked’.

Our propositions concerning the empirical world must also support our own propositions as a real insight and as meaningful, otherwise we are all just speaking empty, dead, and incoherent gibberish.

C.S. Lewis said it well, "To be ignorant and simple now - not to be able to meet the enemies on their own ground - would be to throw down our weapons, and to betray our uneducated brethren who have, under God, no defense but us against the intellectual attacks of the heathen. Good philosophy must exist, if for no other reason, because bad philosophy needs to be answered. The cool intellect must work not only against cool intellect on the other side, but against the muddy heathen mysticisms which deny intellect altogether." ( C.S. Lewis / Learning in War-Time 1949, pg51 )

A good deal of this argumentation (and documentation) is available here: http://rob-lock.livejournal.com/

I call him Charles Manson (or that type). and no-one except you considers him in any way reasonable. I already gave you the definitions of the words that show that reason and logic are related. No logic= no reason.

nwr wrote:

Yes... yes... very good nwr. I am very much making that case. And it is a very Biblical idea as long as we understand the nature of God.

Logical coherence (non-contradiction) must be assumed to be reality (God), in the triune sense extrapolated to us by the apostle John. But before we analyze John’s witness, let’s bear in mind that the Greeks had several ‘terms’ for the English term ‘Word’. The one that John used is ‘logos’ which assumes ‘reason’ as part of its meaning. The term logos is also the etymological root of the English term ‘logic’.

John 1:1 In the beginning was the logos, and the logos, was with God, and the logos, was God. 2 He was with God in the beginning. 3 Through him all things were made; without him nothing was made that has been made. 4 In him was life, and that life was the light of men…14 The logos became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only, who came from the Father, full of grace and truth.





This next quote speaks for itself!

I already said that the CD is not the information. And neither are the amino acids in DNA. It is the arrangement or pattern.

As for causal mechanisms, I don't know where you got that term, but I think you're a bit confused. Both DNA and CD's exchange information to be changed into another form. So both of them are causal mechanisms if that's what you want to call it.

This might help you a geart deal:

http://rob-lock.livejournal.com/ wrote:
Listen to how Paul Davies (theoretical physicist / Arizona State University) admits the real history of science, yet still dodges the implication.

“The worldview of a scientist, even the most atheistic scientist, is that essentially of Monotheism. It is a belief, which is accepted as an article of faith, that the universe is ordered in an intelligible way.

Now, you couldn’t be a scientist if you didn’t believe these two things. If you didn’t think there was an underlying order in nature, you wouldn’t bother to do it, because there is nothing to be found. And if you didn’t believe it was intelligible, you’d give up because there is no point if human beings can’t come to understand it.

But scientists do, as a matter of faith, accept that the universe is ordered and at least partially intelligible to human beings. And that is what underpins the entire scientific enterprise. And that is a theological position. It is absolutely ‘Theo’ when you look at history. It comes from a theological worldview.

That doesn’t mean you have to buy into the religion, or buy into the theology, but it is very, very significant in historical terms; that that is where it comes from and that scientists today, unshakably retain that worldview, as an act of faith. You cannot prove it logically has to be the case, that the universe is rational and intelligible. It could easily have been otherwise. It could have been arbitrary, it could have been absurd, it could have been utterly beyond human comprehension. It’s not! And scientists just take this for granted for the most part, and I think it’s a really important point that needs to be made.”


So science is faith. And it is faith in logic. And that is a very interesting observation since now we must remember that, any logical equation or test requires at least two entities (or witnesses). The coherence of at least two entities becomes the third element in the equation. Assuming the entities involved achieve coherence, then theory + evidence = knowledge. All scientific observation is therefore triune in principle. There is no escaping this reality. No claim is scientifically valid without the testimony of at least two witnesses. If an idea is not testable, repeatable, observable, and falsifiable, it is not considered scientific. All of those qualities assume the law of contradiction to be valid and are dependant upon its application.

Logic is systemic by its very nature. Although our knowledge based upon this faith in logic is not comprehensive, it is our only light. We simply have no other authority for any form of objective revelation. That is not an ecclesiastical proclamation, but is the profound quality of self evident and logical propositions.

So science is indeed a triune and monotheistic affair. Paul Davies understands the history of scientific thought very well. Even so, it appears that the connection is far more implicit than he, or many of us bargained for. Logic has always been so, long before we discovered its power and recognized its whole nature. Logic is our only authority. Without its coherent order, all things would become unintelligible philosophically, and fall to pieces materially.

Colossians 1:17 He is before all things, and in him all things hold together (cohere).

Non-contradiction is the law of laws and reflects the logical and intelligible character of the living triune God. The coherent quality of His work is the intelligibility behind the physical laws, and the power and certitude of our moral laws (love thy neighbor as thy self). Psalm 19:1 The heavens declare the glory of God; the skies proclaim the work of his hands.

On the contrary... here is an example of both simple and complex information.

Phillip Johnson wrote:
“Information at the simplest level is just meaningful text. You can say it’s like the plays of Shakespear or the Bible if you want to pick something noble. It’s like the Los Angeles telephone directory if you want to pick something much more mundane. Perhaps an instruction book, let’s say a cookbook with all of the recipes would be a better example; or a computer program; the operating system of a PC.

Now, in order to have a computer operating system, you have to have lots and lots of that text and instructions. So it’s extremely complex. That’s feature number one, it’s a lot of letters (or digits) in a specific order. And the order is specified, that’s point number two; which is to say that only one complex arrangement will do to operate the computer. If you got another one, you’ve got something that won’t work at all.

So it’s specified complexity. And a third feature is called aperiodic, or non-repeating. And that means it’s not the result of physical or chemical laws, because those laws always produce simple repetitive patterns. For example, you can imagine a book that’s written this way: you put a macro on your computer processor that says reapeat the letters ABC until the printer runs out of paper. And you’d get a book like that, and it wouldn’t be a very interesting book. And it would never get more interesting because the same laws that give you that pattern, ensure that you’ll never get a different pattern, or a more meaningful one.

So the information in the computers operating system, like the information that has to be present to operate all of the cells machinery, is complex, specified, non-repeating (meaningful) text.

And without exception, in all of our experience, you never get anything like that unless you have an author. To get computer software, you have to have a software engineer. To have an encyclopedia you actually need a lot of different authors and editors. To get the plays of Shakespear, you need Shakespear.”

The work of Isaac Newton was very influential in how science is done, and this in turn had a lot to do with how "science" gained its current meaning. Newton was a theist.
