One of the problems with the verification principle of logical positivism
was that it, itself, cannot be verified by the verification principle, and
hence is subject to the charge of being part of the hated metaphysics (and,
I suppose, if it could be verified it would be subject to the charge that it
was a circular argument). But I would get around the problem by stating the
principles by which science works thus: IF you want to predict the weather,
build planes that fly, make sick people better THEN you should do such and
such. By putting it in this conditional form there is no metaphysical
component.

Sorry if I have misunderstood, and if I have been unclear or tangential.
Several posts back you spoke of positivism being deficient because "a closed
system which is supposedly totally explainable will always have at least one
fixed point that is unexplainable". I read into this an implication that God
would solve the problem because he could be outside the system, indeed
outside all possible systems. But this runs into two problems. The first is
that positivists are in fact very modest and make no claim to explain
everything; the very opposite, in fact. The second is that the concept of an
entity outside all possible systems, and therefore requiring no cause,
design, meaning or any of the other things allegedly necessary for the
universe and its components constitutes a restatement of the ontological
argument for the existence of God, an argument that is 900 years old and has
been rejected as invalid even by most theists.
