    I've asked several times for your answer to Hume's refutation of the
    Intelligent Design argument. You give no response, yet continue to
    claim that ID is a strong argument for the existence of Essence.

    ham:
    Hume's so-called "refutation of an intelligent creator" is nothing
    more than the empiricist's dismissal of *a posteriori* knowledge.

    msh:
    A proposition is knowable a posteriori if it is knowable on the
    basis of experience, so I have no idea what you're saying when you
    claim that empiricists dismiss a posteriori knowledge. Your
    statement makes no sense at all, so I won't even try to address it.

    ham:
    Since nothing like an "intelligent designer" is implanted in our
    minds, we cannot infer intelligent design from our sense experience.
    Reason has no right to add anything to this experience, or to alter
    the information received by imputing meaning to it. Where, then,
    does the notion of ID come from, and how do we recognize it? The
    analogy he uses is as follows:

    "If we see a house,. we conclude, with the greatest certainty, that
    it had an architect or builder because this is precisely that species
    of effect which we have experienced to proceed from that species of
    cause. But surely you will not affirm that the universe bears such a
    resemblance to a house that we can with the same certainty infer a
    similar cause, or that the analogy is here entire and perfect."
    [Dialogues, Part II].

    By setting up an inappropriate analogy and claiming that the universe
    does not resemble a house, he says we can't conclude that there is a
    universal architect. Pardon me, but that argument is really dumber
    that it is weak.

    msh:
    So, let's see, you dusted off your old copy of Dialogues Concerning
    Natural Religion, carefully reread all 12 parts, and have now
    summarized Hume's criticism of the design argument as "dumb," citing
    as evidence a single quote from Part 2, which, BTW, you have
    completely misinterpreted. Let's at least give the old Scott a fair
    reading, shall we?

    For anyone interested in what Hume actually said, as opposed to
    simplistic quotes pasted out of context from some ID infatuated web
    site, here's a link to the Dialogues:

    http://www.anselm.edu/homepage/dbanach/dnr.htm#A1

    We need to keep in mind that Hume’s language is at times poetic and
    dated, and, of course, not up to snuff regarding our current
    understanding of the physical universe. Nevertheless, though the
    Dialogues were written more than 200 years ago, they are still among
    the most impressive, and unanswered, criticisms of the Design
    Argument.

    A careful reader of the dialogues will discern no less than six
    objections to the Design Argument. Since any one of them is
    sufficient to put the Design Argument on ice, I'll spare you an
    analyis of all six. Here are the four I find most interesting,
    though I will be happy to discuss the other two if you so desire:

    1) The analogy between the universe and man-made items is very weak.

    This is the point being made in the "dumb" quote Ham has clipped
    above. Hume's house analogy isn't dumb; in fact, as is plain from
    the surrounding paragraphs, his analogy is intended to show the
    weakness of analogies such as "the watch" that offered by Paley more
    than 50 years later. For an analogy to be convincing, there must be
    substantial similarity between the analogy's object and target. I
    know my heart pumps blood through my veins, so I can safely infer
    that your's does the same. There is a strong similarity between you
    and me in that we are both human animals. But is the same inference
    valid between a man and a sunflower? Can we really infer a designed
    universe from the the fact that a watch was designed by a man? It
    should be clear that the universe does not resemble any made-made
    artifact at all. The analogy simply doesn't hold.

    2) - Analogies to the the origin of the universe are meaningless,
    since the "creation" would be a single, unprecedented, and in fact
    unique event.

    We have only one universe. Analogies are meaningful only when we can
    compare and contrast a variety of objects or ideas. It is both
    meaningful and useful to compare the attributes of humans,
    sunflowers, tides and watches, but to what do we compare the
    universe?

    3) Intelligence is not the only active cause in the world.

    It's obvious that natural phenomena do not require creative
    intelligence to occur. Perfectly symmetrical crystals of quartz,as
    well as dozens of other minerals, will form during the cooling of
    silicon rich magma, and this process is understood without reference
    to intelligent design. The ebb and flow of tides can be explained in
    terms of simple well-understoof gravitational interactions. No ID
    required. In short, there is no reason to believe that because some
    things are intelligently designed, a watch for example, that
    everything in nature must be ID as well.

    4) Even if signs of intelligence are everywhere, it does not follow
    that intelligence created the universe.

    This is my personal favorite of Hume's objections. Think of the
    rovers NASA has landed on Mars. They send back their data and
    eventually "die." Now imagine that intelligent life evolves on Mars,
    say several million years down the road, and a smart Martian stumbles
    across one of NASA's rovers. To her, the rover is clearly too
    complex to be anything other than the result of intelligent design.
    Is she logically justified in offering the rover as proof of the
    intelligent design and creation of the universe?

    ham:
    I find Paley's "Watchmaker" argument a far more convincing defense
    for ID.

    msh:
    I'm sure you do. Still, I'll snip the pasting of Paley's watchmaker
    argument, as it was made 50 years after Hume had refuted the
    formulation in general. I've always thought that if Paley had been
    reading philosophy rather than trying to invent arguments for the
    existence of God, he would have saved himself considerable
    embarrassment.

    ham:
    That argument, as you probably know, is still effectively used by the
    ID proponents.

    msh says:
    I have no doubt that Paley's argument is effectively used by ID
    proponents in convincing ID enthusiasts that their desired belief is
    logically sound. Of course, the argument has NO effect on anyone who
    has actually read, and is capable of understanding, Hume's
    criticisms.

    msh said earlier:
    In the absence of time, the causality principle is meaningless. Even
    in the presence of time, any notion of an uncreated source, primary
    cause, unmoved mover is logically indefensible, unless you simply
    assume the truth of what you are trying to prove.

    ham:
    Or, unless one assumes that a primary cause is a primary source, as I
    do.

    msh says:
    Exactly. Your arguments will never fail, if you simply assume what
    you are trying to prove.

    For now, I'll snip the stuff re the Ontological argument, since it is
    off-topic for this thread, and because your reference to Clinton
    caught with his pants down made me laugh. However, I do want to
    address this point...

    ham:
    I make the claim that Essence [e.g., God] "is" without the
    contingency of either "being" or "existing". From a rational perspective, you'll
    tell me that makes no sense. But who says that ultimate reality must
    conform to man's reason?

    msh says:
    You are the one who claims that Paley's analogy, a rational argument,
    supports the notion of an intelligent creator of the universe, so you
    obviously believe that reality conforms to man's reason. Why then do
    you claim otherwise only when reason works against your desired
    belief?

    Thanks,
