David,
I am so sorry I cannot pay more attention to these threads. And I am truly
not being critical or cranky when I raise issues here on your posting. I
find your views quite interesting in fact.
But the below statement just boggles my mind:
> Gravity is no
more or less the real cause of planetary orbits than mutations and
natural selection are of evolution.
My belief is, yes, the physical laws were contrived when they were made. So
the gravitational constant, for example, was tinkered with, yes. But after
the laws were created they have gone along on their own and go along on
their own. No guidance is necessary. So yes, I'd indeed say gravity is
indeed the cause of planetary orbits. And this isn't going to change unless
brane theory shows us that, yes, their is another world just a tiny distance
away from our world at every point, and there are "ghosts in the
machinery" modifying the fields moment by moment, making them vary to
produce various results. So I guess we just disagree.
As far as NS, maybe I am naive, but I view it as needing something to
select. And thus it is the creation of new information, well the question is
whether this creative process is all natural, or not - that alone seems to
be the point of contention as I understand it. The issue is not what NS does
after the information is created. I have a very poor understanding of
theories of how new information is created. But NS is (to me) besides the
point. You may perhaps assert that NS creates the information. But thats
not what was taught to me in our labs on NS. So I am not really following
what you are saying.
So I don't see the need for guidance in those phenomena which are purely
natural. Only tinkering for those phenomena which are not natural and would
not occur without tinkering. I thus suspect we might have two fundamentally
incompatible viewpoints. Which would be interesting. But it must produce a
lot of gaps in communication.
Best Regards,
Dave Clounch
