That's the part where I described the coffee cup as still exchanging heat back and forth with the environment (you can imagine this at the molecular level if you prefer, with molecules from the coffee exchanging momentum with molecules from the environment through collisions), but since the coffee is at the same temperature as the environment the net result of these dynamic exchanges is zero. --Percy

quote: Yes, Jar, I corrected the Know-no typo. Don't worry, I left the original quote unedited so that your response still makes (sense?). I also changed my qualifying terms into italics.You seem to have ignored my qualifiers.(Try adding them to a google search for an accurate definition of warrant,in regards to my usage).I presume you are familiar with boolean logic, and that should be no problem for you. Btw a warrant as used in a "warrant-preservation" model is not the same as a warrant as used in a logical argument.
quote: If by topic you are refering to the term warrant as it applies to a logical argument then no I am by no means clueless of the topic!If by topic you are refering to all the various usages of the term warrant,then again I'm not clueless.I may not know all of them, but I have no difficulty deriving a meaning, if sufficient context is provided.(In your vernacular, I would say) "Shit man I'm no SimpleSimon". My interests include; reading(including A-Word A- Day), chess, and solving cyphers (Cyberquotes-in the Sac.Bee newspaper)(I also do the scrabblegrams,crosswords,scrabble,boggle,etc.). quote: Intutionist ? Pretty arcane term there. And one that I agree is totally irrevelant in this topic.

Well so far, you have been unable to present a general principle that explains why your use of the word "warrant" is relevant to this thread.
Perhaps if you have something of relevance either on why you think the term warrant is relevant or on the subject of the thread, now might be a good time to present your evidence and to explain the general principle that explains why your evidence is even relevant. Aslan is not a Tame Lion

I think Percy thinks he has a warrant... quote: war·rant n. 1. Authorization or certification; sanction, as given by a superior. 2. Justification for an action or a belief; grounds: “He almost gives his failings as a warrant for his greatness” (Garry Wills). 3. Something that provides assurance or confirmation; a guarantee or proof: a warrant of authenticity; a warrant for success. 4. An order that serves as authorization, especially: a. A voucher authorizing payment or receipt of money. b. Law. A judicial writ authorizing an officer to make a search, seizure, or arrest or to execute a judgment. 5. a. A warrant officer. b.

quote: Percy, I'd settle for an explanation that works. I don't need more examples of Stasis and negative-feedback systems.I understand those, and can list off a bunch of examples myself, as I suppose most of you can. For example, in physics, a standing wave is an example of stasis(with phase and frequency being the controlling inputs). What I would like is a mechanism and a justification that it can be applied in the specified (general) case.

If you want to be understood then you'll want to use words in ways your audience understands. Otherwise we'll end up wasting lots of time trying to figure out what you're saying instead of discussing the topic. Just like now.

I'll second Dwise1 on this. There have been many attempts at explanations in this thread, and while we can tell you have problems with them, it isn't at all clear what those problems are. --Percy

Percy, he is using "warrant" to mean the General Principle, inferences and assumptions explaining why evidence is relevant to some claim.
It's pretty much irrelevant in this thread and has been pretty well covered in the posts. It was, though, a major scoring point during Middle School debates. Aslan is not a Tame Lion

An example of stasis
-------------------------------------------------------------------------------- quote: can not ? I don't think so. If the reduced speed is compensated by some other survival trait/tactic I don't see any reason why those changes couldn't spread.
quote: And the predator would also be subject to this new selective pressure, now wouldn't it ? Granted there are other ways to cope with cooler temperatures; fur(hair+air) and feathers come readily to mind. So the form could change as long as the selective pressures balanced out.

quote: I'm sorry Pesto, I forgot to qualify this statement.(I was/am a bit frustrated with the type of replies I was/am seeing here). I was again refering to the general case dwise1 was using...not the limited case(one selective pressure)you are using.
quote: Sounds a little like the moth camo example i've seen many times(and believe in). Ok., lets say your'e skroats are a type of moth . The bright dayglow orange wouldn't neccessarily occur all over the mutated skroat's body. If orange spots occured, they wouldn't always lead to the mutant being eaten. Mimicry is another survival trait. Some moths have spots that look like giant eyes. Some other traits would also allow the new(mutated) moth to survive. If it tasted/smelled bad, was toxic or poisonous for example. A lot of brightly colored animals are dangerous or just not good meals. Again I'm not saying there are no negative feedback systems in nature. I'm arguing against a general case. I think most extreme Stasis is due to isolation . Take Tribolites, Coalanths, and Catholic Scientist's crocodiles as examples. Water is a good radiation shield(less radiation induced mutations).Coalanths are very sensitive to light and hang out in deep caverns (I read). Tribolites and crocs also had/have the armor thing going for them. Edited by Simonsays, : Toxic typo.

You're saying that a book for middle school is using warrant in an obscure and non-standard way? Could you provide the text on p. 70? By the way, the title is What's Darwin Got to Do With It: A Friendly Conversation About Evolution.
1.) Ideal genomes don't exist in nature. Dwise one seemed to understand that when he qualified it in one or two of his postings... Then he went back to an ideal genome with one set point. I believe for any given environment there are so many workable gene and trait combinations that the use of ideal genome is meaningless/inapplicable. Dwise is not claiming ideal genomes exist in nature. You're taking his simplifications made for the sake of exposition and somehow concluding that he's claiming that's what exists in nature. He's not.
2.) Negative feedback mechanisms are specific/limited. I don't think Dwise1 or anyone else has shown/identified a general negative feedback mechanism. Negative feedback mechanisms abound everywhere. They are the primary type of feedback mechanism for producing useful results by keeping systems within reasonable operational limits. Positive feedback mechanisms spiral out of control, like microphone feedback.
3.) I think most evolutionists equate Evolution withchange That's how it is refered to in every dictionary I looked at...and in the thesauruses too (Evolution is not synomynous with adaption). Nowhere is it equated with adaptation. Adaptation is listed as an aspect of evolution, but that's it...Development and progressive change were common terms used there. If you're looking for a one-word synonym for evolution, you're not going to find it. Change over time, adaptation over time, descent with modification, natural selection, these are all part of the definition of evolution. How much each is emphasized depends upon how much detail you're seeking. --Percy

By the way, the title is What's Darwin Got to Do With It: A Friendly Conversation About Evolution. OK, that helps to explain why SimonSays has been using unrecognizable language. That's an ID book. ID uses language and invokes concepts that sound really impressive to the general public, while at the same time the IDist is saying nothing. ID Jive. Like the airline stewardess, we don't speak Jive.

I just want to point out, again, that "warrant" was part of no logic class I ever took, nor was it ever covered in any discrete math class I took pursuant to the CS degree I was working on (where Boolean algebra was covered), so again, "warrants" just aren't a part of developing logical syllogisms as logic is currently taught, at least in my experience.
But, again - we talk about science in this forum; and while it wouldn't be accurate to say that scientific reason shouldn't be "logical" (that is, in an informal sense, meaning "reasonable"), it's certainly not the case that science proves things with logic. Rather, scientific arguments are supported by evidence. Nit-picky criticisms about logical forms simply don't have a place in science.
All men are mortal (this is the evidence) Socrates was a man (this is the warrant. It is saying that Socrates is an example of a group we call "men.") Therefore, Socrates was mortal (This is the conclusion.) See, this isn't even right. Syllogisms are comprised of three parts, the major premise, the minor premise, and the conclusion. "All men are mortal" can't be evidence, because it's not possible to have made an observation that proves that all men, every single one who ever lived and ever will live, are mortal. Obviously at any one time there are more than 3 billion men right now whose mortality has yet to be established, because they're not dead, yet. "All men are mortal" is the major premise as it has the widest scope."Socrates is a man" is the minor premise, being of narrower scope. "Socrates is mortal" is a simple application of categorical logic. None of this has anything to do with science - a process where observation leads to hypothesis, which leads to testing (via experiments or further observation), which leads to refinement of theory, which ultimately leads to communication and verification of results, the most important step. At no point does anything like a logical syllogism occur.

Describing science as working differently than it actually does seems to be all to common in ID.
My first exposure to ID founder/co-founder lawyer Phillip Johnson was on a 1981 Nova -- as I recall after he had written "Darwin on Trial" -- where he was insisting that science had to follow courtroom rules of evidence. My immediate and enduring reaction was "What an idiot! Science isn't a courtroom proceeding in which a case is being made and argued, but rather an on-going police investigation in which clues are sought and found and from which hypotheses are formed and tested -- tested in large part by trying to figure out what other clues there should be and where to find those clues." Johnson was trying to force science to be something very different from what it is and to force it to operate by a foreign set of rules and standards. Pretty much what ID is continuing to do as it tries to force science to employ supernaturalistic explanations. According to amazon.com, one of the authors of SimonSays' book has an advanced degree in theology. Theology does indeed rely almost exclusively on formal logic, since it has no real evidence to work with -- the only evidence theology has are what the religion's founders and leading theologians had said and written, hence only argument by authority. I suspect that that author had written the passage in question. Now, SimonSays, in the book did that author go on to insist that these rules of formal logic must be applied to science? That only those findings of science that can be expressed in terms of rigorously devised syllogisms may be deemed acceptable? In other words, was that book's author also insisting that a foreign set of rules and standards must be applied to science? BTW, I did come across that book in a bookstore some years ago. I browsed through it and recognized it as yet another load of anti-evolution taurine coproforms, little different from standard creationist fare except that it left out young-earth claims and was more adept at shovelling taurine coproforms than most creationist hacks.
