    Hi Bob,

    > No, I have not yet read Pirsigıs books.

    That's a shame.

    I hope she is successful, and I hope you then decide to join our discussion.

    That sounds like a very healthy suspicion. I wouldn't expect to find the
    answer to the ultimate question of life, the universe, and everything in
    Pirsig's books, either.

    I am interested. I've been thinking about my summer reading list.
    What "land of truth" are you referring to?

    I think you took my question the wrong way. The hope in this discussion is
    that all of our contributions to the list will be measured according to
    their quality of thought irrespective of the credentials of the thinker.

    I was just curious about your background. (I'm a high school teacher, by
    the way.) I wasn't questioning your scientific knowledge. I know that the
    explanation you gave is the one that is widely accepted in scientific
    circles and accepted though misunderstood by the majority of non-Bible
    thumpers everywhere. (Many will say, for example, that they believe in
    Darwinian evolution but think that God guides evolution, not realizing that
    they have just contradicted themselves.)

    Actually, the only requirement for participating in this discussion is to
    have read Pirsig's books, which makes me somewhat hesitant to engage with
    you at this point.

    >Science, both the process and the current results,
    > are a love of my life.

    I share your interested in science, but I don't consider it a complete
    description of reality. Any explanation that claims to be a complete
    description of the universe, however, would certainly have to include the
    results of science.

    My point was to to drive home that to ask about the purpose of anything is
    to step outside the scientific perspective that attempts to be objective.
    Science doesn't say that evolution and gravity have no purpose. On the
    contrary, to ask about purpose is simply not a scientific question. You may
    as well ask what gravity's favorite color is.

    Physical laws only describe how things behave. A scientist can ask "what
    does it do?" but not "why does it do that?" The first question is objective
    and can be studied from outside. The second is subjective and can only be
    answered from within.

    Do you really think that you are no better than a dandelion? Would
    everything be better if we only realized that nothing is better than
    anything else? If only, like science, we all valued not having values...?

    I don't look to a God that is external to the universe to explain such
    things if that's what you mean.

    As for whether dice have a purpose, consider the following:

    Suppose 50% of a large population prefer chocolate ice cream and 50% prefer
    vanilla. If I select a person from this population and offer him ice cream,
    the selection he makes will fit the concept of probability.

    I could use a random number table or flip a coin to mathematically model the
    situation. But that doesn't mean that the choice itself was random. If
    you ask the person why he chose what he did, he will say that he chose it
    because he prefers it.

    The scientist studies selections and describes them objectively, but
    whatever is making the selection has a completely different perspective.

    From the scientific objective point of view, preference looks like a
    statistical tendency. More universal preferences look like causes. The
    objective perspective can't see values. (As Hume pointed out, you actually
    can't see "causes" either.)

    Back to the dice. The point is that if you want to know if the dice have a
    purpose, you'd have to ask the dice. If it sounds silly, then un-ask the
    question. It certainly can't be answered objectively.

    > Randomness is a well-accepted part of our universe. (It is not a cause for

    As you suggest, it is a description, not an explanation.

    Randomness is a concept, a mental construct. It is not part of objective
    reality. It is an element of some of the most useful models we have
    constructed to try to understand the universe. But don't confuse scientific
    models of reality with reality itself.

    >Heisenbergıs Uncertainty
    > Principle comes into play here. You can know the direction OR velocity of any
    > electron. You canıt know both values at any moment of time.

    Again, "it's random" looks more and more like "I don't know." In this case
    Heisenberg further said that we can't know. This is a limit of scientific
    inquiry, not a characteristic of the objective world it studies. It also
    suggests that objectivity itself ultimately fails.

    (Do you want to know if Schroedinger's Cat is dead or alive? It's simple.
    Just ask the cat.)

    Pirsig offers a third alternative to randomness v determinism. You'll have
    to read his books.
