- What is it that makes people want to make oracular pronouncements
- about the "intent" of physics, and the "mistakes" of people who don't
- understand its intent? How about phrasing your beliefs a little more
- humbly: such as "I think that people make a mistake in assuming that
- QM somehow rules ...", or "I don't think that QM is capable of going
- beyond making predictions"?
-
- I believe that science is *not* about making predictions, it is
- primarily about satisfying our curiosity about the world. A more
- recent goal is to allow us to manipulate nature and have it serve our
- end, but that is hardly applicable to quantum gravity or string theory
- or General Relativity.

- Well, my apologies for being so dim-witted, but I consider your
- response to be a prime example of an incoherent mess. I just don't
- know what phrases like "a classical notion of the way things are `out
- there'" mean.

-
- Well, I consider your pronouncements about the "intent" of physics to
- be metaphysics, and they certainly aren't of much help. And do you
- really think that religion helps people to resolve philosophical
- questions about quantum theory? Pardon me, but your advice doesn't
- sound very useful to me.
