We label your church with a big sign saying "The bible is a collection of stories ripped off from earlier religions and used as a means for the leaders of the Roman empire to subjugate their people. Many different, conflicting, versions of the stories exist within the bible itself and many more stories were edited out primarily as a means to allow a few evil people to pillage and murder the supporters of the other equally valid stories. There is little, if any, evidence that there ever was a Jesus and the gospels were written long after his death by people who never met him if he ever did live."

    Fortunately ID continues to fail on many other major points of science. First it does not actually solve the problem it merely adds another layer.

    That complaint is in fact Occam's razor- the idea we shouldn't add additional layers of complexity. If Occam's razor is in fact logically unsupportable, then this point is lost.

    That chains continues so long as there remains a creator and a createe.

    For all science knows, there is always a creator and a createe- that is, there are no uncaused events, everything is causual. So therefore, that's an argument FOR ID. The extraordinary claim which requires extraordinary evidence is that there is a break in the chain of cause and event; or that there can be a break in that chain.

    Actually Occam's razor would lead one more directly to ID. Evolution requires many assumptions, ID requires only the assumption that some invisible unquestionable magical being in the sky did it all. Since Occam's razor uses the number of assumptions and not the probability of the assumptions then Evolution would be shaved by the razor if ID were a valid scientific theory in the first place.

    Now that's an interesting idea- that evolution requires *more* assumptions. I've been going on the idea that evolution requires the same number of assumptions- that the assumption of an indeterministic, non-causual universe is just as outlandish, complex, and improbable as the assumption of a creator. Can you explain the idea that evolution requires more than that? And how does that differ from ID's theistic evolution theory (which I have a problem differing from atheistic evolution to begin with- their predictions and assumptions seem entirely equal to me)?

    There is no question at all. It isn't science. It is religion.

    Agreed- but the problem is, science as it's taught at the high school level is ALSO a religion.

    Well, then you went to a very bizarre high school. At mine and that of everybody I know, the scientific method was taught and it was made explicitly clear that theories are the best current explanation of the available evidence but they are subject to change as more evidence comes to light. Heck, we started with that lecture in junior high and it was reinforced every year.

    Reinforced how? Were alternative explainations ok on tests for instance? Were you encouraged to come up with your own theories even if they were different than the textbook? Or was it like my highschool biology class: A tacit admission that evolution is just a theory- but the whole class based on it and any attempt to question it's assumptions was penalized heavily in the grade book?

    Just because you had shitty teachers doesn't mean the rest of us did.

    I'd call any teacher who relies on the court system to censor ideas from the classroom a shitty teacher.

    No, the trolling was where you took the statement that science has never claimed to have *all* the answers to *everything*, and then said yes it does since your high school science tests were like that.

    Well, that's a correct statement. "science has NEVER claimed" is a statement easily falsifiable by a single instance of someone claiming to teach science claiming that.

    No it doesn't. It's religious creationism and nothing besides.

    Then you apparently don't know the different ID theories very well- ID covers everything from Young Earth Creationism to Theistic Evolution.

    Wrong, universal means that the rules etc. apply everywhere.

    If the rules apply everywhere- to everything that exists- in what way does this NOT imply that science has an answer for everything?

    For example the theory of gravity is often said to be universal. That means it applies in the whole universe, not that the theory of gravity can explain everything.

    Ok- so what you meant to say is that the scientific method is limited to the things it can explain.

    You can also check for the word's meaning: http://en.wikipedia.org/wiki/Universal

    I don't accept Wikipedia as a primary or secondary source, sorry.

    As long as there is a possibility to disprove that explanation (otherwise it would not be scientific), I don't see your point.

    All that is is being dogmatic about science- being religious about science. That's VERY dangerous in the long run. Science should not repeat the mistakes of religion.

    What do you want anyway? Equal rights for all explanations? That would be the same as no explanations at all.

    I'm fine with that too- explainations have a tendency to be exclusionary and limiting. But yes, Equal Rights not Special Rights. I contend that by placing science above other religions, we are establishing science as a new religion, to be taught by law to all.

    Really? What pre-death predictions do religions make?

    How about the one that if you do something to somebody else that is perceived by them as evil, they will find a way to do something equally evil to you? Of course, that's just Newtonian physics applied to ethics- but the prediction of it predates Newton by about 9,000 years.

    You think school children should learn Super-String theory?

    Yes, if you're going to be consistent with the idea that science can be wrong.

    You still don't understand what science is.

    Either that- or you have such incredible faith in your own perceptions and senses that you don't understand that other people may have different perceptions and senses.

    (Apart from that you have trouble with logic: You say science is taught as a religion because it is not like religion and has to become like religion to become "true science"? That just doesn't make ANY sense at all)

    No, what I'm saying is that science is already being taught just like a religion- and thus we might as well teach all religions equally. Alternatively, you could teach true science- and admit that science is inaccurate and arbitrary in even the best circumstances- in which case you can limit science class to only the religion of science, but you have to add a bunch of other classes for other religions and make them all electives. Either method is fine by me, because neither one puts science on a pedastal as being "better" than all other religions.

    The reason why there are only few (usually just one) accepted theories for a given phenomenon is that science is constantly weeding out incorrect theories. That is the only way to actually *LEARN* something.

    No, actually, it's not- people learned for centuries before exclusionary modern science came on to the scene. It may well turn out, a few millenia from now when the religion of science becomes mature instead of just a cult, to be the *best* way to learn things- but the jury's still out on that.

    Then you would agree with say, a statement to that effect in grade school science classes.

    Axioms are another way of handling difficult questions. In this case, we have questions, such as "why is 2 + 2 = 4?" that have infinitely many correct answers (set of axioms), but we can usefully apply only 1 answer at a time, otherwise we would not be logically consistent.

    Being logically consistent is not necessary. Logic is just another philosophy- another religion under this idea. Another system of beliefs to take on faith. There are many such philosophies that are internally logically consistent, which don't make sense in a different philosophy.

    The deeper question, "why is some set of axioms true?" is unanswerable for all sets of axioms if you refuse to accept that they are self-evident.

    And I do so, at least for the idea that religion is a science, refuse the idea that ANY religion is self-evident before it is stated. Axioms must be taken on faith that they are true; we can't prove that reality exists let alone that axioms are self-evident.

    We know they are unanswerable (Incompleteness). That does not make axioms useless, or the use of axioms evidence that we are taking things on faith.

    Why not? Since you can't claim in all worldviews that any set of axioms is self evident- that sure looks like faith to me.

    Use of a tool does not imply "belief" in a tool in all possible situations.

    Faith doesn't need to be in all possible situations- faith might only cover a single situation.

    We use Occam's Razor to justify picking the simplest answers (sets of axioms), and run with that.

    That justification has nothing beneath it but faith. But that's ok- all justifications are about faith- faith doesn't automatically make things correct or incorrect, just lacking in evidence.

    Science has a totally deserved reputation.

    Actually- until you prove that axioms are self-evident, no it doesn't. If it truly deserved that reputation, it wouldn't be so limited.

    Here you are, posting on Slashdot via the Internet, which is one of the most recent fruits in a long chain of scientific advances, some of these advances being the understanding of electricity, information theory, and materials science, and you're trying to ram the square peg of science into the round hole of religion, saying science is no "better" than any other religion?! Do you believe you exist?

    I believe I do, but I have no real PROOF that I do. Nor do I have proof that the computer I'm sitting in front of exists, or that any of this chain of scientific advances exists. I believe that they do- but that belief is religious in nature, it's faith that there is a reality. I can't prove that there is a reality. So actually, science is just another round peg that fits through the round hole.

    How do we know the world is more than 5 years, or 5 minutes old?

    I don't. I choose to believe that, and have faith in it, but it's no more than faith.

    We don't. We can't. Scientific evidence, in addition to the evidence of our own senses and memories, says the universe is more than 5 minutes old.

    Yes, but we choose to BELIEVE that evidence exists- we have faith in it.

    Accepting the evidence of our senses is not a matter of faith,

    Completely incorrect.

    it's a matter of rationality. You veer into semantics if you try to argue that rationality is faith.

    Rationality is not accepting the evidence of our senses- if that was so, people hallucinating would be completely rational. Rationality is insisting that the system of faith we choose to believe in, the religion we choose to believe in, is logically consistent and explains the evidence of our senses. There are rational religions and irrational religions- I would certainly put science among the rational ones if that helps any. But that doesn't mean we're accepting it on faith any less.
