    My point was that it might be a fact that the YEC (and even my) arguments
    on the SLoT are "subtly false" but that does not necessarily make them
    "bogus". It is David's personal *value judgment* that they are also "bogus".

    I said "I suspect" David may in fact not have any such "hidden agenda"
    but he has given me grounds to suspect that he has.

    See previously. I said "*my* arguments regarding the SLoT". The YEC
    arguments in Ratzsch's quote were no more my arguments than they were
    Ratzsch's.

    My arguments are similar to some of the YEC arguments, but they are
    not identical.

    I'm not even sure that David has *ever* known what my arguments were!

    See previously. The "cosmic and earth-based arguments described in the
    Ratzsch quote" don't represent my position. They represent the *YECs*
    position. My position has similarities with the YECs position, but it
    is not identical.

    Well, let's hope that David does "correct" his "thinking and any

    I do not necessarily disagree with the above, except the bit about
    "disorder". But I don't want to debate the above until we get past
    these preliminaries. I also want to work from what *I* have said,
    not from what David has said.

    I don' necessarily disagree with the above either.

    But why does David keep mentioning that "It does not violate, go against,
    oppose, etc. the 2nd law"? I am not claiming that it does, and as he
    shall see (if we ever get to it) I was not claiming this even in 1996.

    I thank David for this. But I do assume that from his confusion about
    the Ratzsch quote and his continual mentioning violating the 2nd law,
    that he is like the man who has a hammer and everything looks like
    a nail.

    I would appreciate David posting where I have "abused David" that was not

    Because David just makes assertions without references. I need to know
    how much weight I should give to those assertions.

    If David has the "modern stat mech book" he can quote from it. Otherwise
    it is just his unsubstantiated assertions as far as I am concerned.

    Yet this is *exactly* what David is doing!

    We have had this argument before. It is a scientific myth about science
    not being based on "appeals to authority". Science is so specialised
    these days that all scientists rely on the authority of other scientists.

    How is a layman (or indeed a scientist from another field-which is the
    same thing) to evaluate a technical physics argument from a physics
    professor, which is apparenty beyond the ability of introductory physics
    textbook authors to state accurately?

    If we did not post quotes with references, these debates would just
    degenerate into everyone's unsubstantiated assertions.

    David is welcome to his preferences, but he should not try to force
    them on others. I personally *like* to see statements backed up with
    references.

    Again, this is unnecessarily provocative.

    Thanks to David for this. I did not *have* to know it, but it is
    useful in evaluating how seriously to take David's assertions.

    >SJ>Has David written physics textbooks?

    DB>No. I have toyed with the idea of writing a thermal physics text

    OK. I thank David for this.

    And for this. I note with interest that David uses the term "disordered". Is
    this the same "disorder" as in some definitions of the SLoT?

    I did "pay attention" to this but it was too vague. It could mean anything.
    Some Evolutionary Creationists say they do not consider themselves to be
    theistic evolutionists. saying what one isn't is not saying what one is.

    Thanks to David for this also. It will be interesting to see what position
    David eventually adopts. If he maintains his stand on "methodological
    naturalism" it is hard to see how he could ever be anything other than a
    type of theistic evolutionist.

    More unnecessary rudeness from David. I believed my questions were reasonable
    in the circumstances.

    [...]

    Now that I have got to the end of this preliminary post, in view of David's
    continuing gratuitous intimidatory remarks, I am prepared to continue this
    SLoT discussion with David only on the following *non-negotiable* conditions:

    1. David refrain from making any further remarks about the style of my posts;

    2. David accept (or at least not reject) my quoted definitions of the second
    law of thermodynamics, as it relates to evolution, from mainstream physics and
    biology textbooks; and

    3. David cease stating (or implying) that I claim that `evolution violates
    the second law of thermodynamics'.

    David is free to reject these 3 conditions, but in that case this whole SLoT
    thread will be at an end. Moreover, if David does accept these 3 conditions,
    but later on at any point in our subsequent discussions, he breaches them,
    this SLoT thread will, at that point, be at an end.

    I would not normally make these conditions but I believe in this particular
    issue, which David himself has said is "subtle", the whole debate will
    probably turn on fine points of definition. In such circumstances, David's
    continual interjection of `noise' in the form of gratuitous intimidatory comments
    about my style of posts, etc, and his rejection of the quotes which form the
    very basis of my arguments (in view of the fact that David is an Associate
    Professor of Physics and I am a layman), would make continuation of the debate
    a waste of everyone's time.

    The ball is now in David's court.
