Re: [asa] Easter Island WAS Does the flagellum prove Genesis?

I think the last two posters are missing the point here.

Moorad talks about assigning a zero prior probability to the existence of
God, but I never said anything of the sort.

What I said was that it was impossible to specify a prior probability for
the existence of God, or indeed of shape-shifting staffs. The value you
pick is entirely dependent on your own belief. At a questionnaire in the
theoretical physics department at my work once, people were asked to assign
probabilities to various events, such as England winning the World Cup
Football (that's "soccer" to our USA friends). To the "God exists"
question, one person put down zero and another put down 10^-100. The
10^-100 person says to the zero person "now that's what I call faith"! Did
I put down 1? Well, not exactly, I put down 0.9 recurring, but it brought
home to me how silly the exercise really was. If I'd put down 1, I wouldn't
exactly be making a scientific statement, would I? If I'd put down
signficantly less than 1, I'd be indicating doubts that I didn't have. It
was the sheer impossibility of making an objective and truthful statement
that led me to put down the joke answer of 0.9 recurrring.

My view is that there is no way to assign a prior to the existence of God in
a scientific fashion, so one can't make scientifically valid deductions from
evidences of design. The design "argument for God" only works if your prior
probability differs signficantly from zero. But if it's already your belief
that God exists, then you don't need to make the design argument. By
contrast, an atheist is not likely to be persuaded by such an argument.

John, you contend that the analogy is close enough. I beg to differ. There
is a whole world of difference between a prior of close to zero and a prior
of close to unity. It comes down to your own faith position. You accuse me
of failing to describe supernatural events. But supernatural events are by
their very nature unpredictable, and therefore outside the realm of
scientific exploration. If such events were predictable (for example if
such things happened as in the world of Harry Potter by saying the right
spell or by waving a wand in the right manner), then they would be natural
and not supernatural). But miracles occur by God's grace, not by scientific
cause and effect.
