Re: evolution evidence

I would like to jump into the middle of the conversation between Lloyd Eby
and Kevin Wirth. I support Lloyd's contention that Kevin requires too much
of scientific theory. Kevin expouses a postivisitic view of science which
unduly constrains what science can and cannot do. This positivism is a
frequent and poor critique of science by some on this reflector. The major
problems are that by requiring theories to be supported by explicit proof
denies the inherently speculative nature of theories. Furthermore, if one
requires such positivistic evidence for, say the theory of evolution, then
one must be prepared to require a similar level of credence to whatever
theory is proposed as an alternate to evolution.

I would add that alternative models to explain origins suffer from their own
problems in this area, yet those who criticise evolution theory on this basis
do not seem willing to apply a similarly rigorous of proof on their pet
models. What model for origins are not "linked with speculative and
imaginative STORIES"?

I also protest. This criticism is too much like the complaint of logical
postivists that atomic theory is full of gaps, leaps and speculations
because no one has ever seen an atom. Borrowing from an earlier debate I
had with Walter ReMine, different types of knowledge carry different degrees
of certainty of truth. Because the evidence for evolution is not as
convincing as the evidence that the Red Sox currently lead their division,
doesn't necessarily minimize the value of the evolution hypothesis. If the
evolution hypothesis is wrong, science really will not suffer because
science needs the freedom to test both right and wrong hypotheses (stories).

Evolution (and its derivatives) is the only mechanistic hypothesis currently
available for testing because it tries to explain the naturalistic methods
by which God created, and not whether God did it all at once, or in spurts.
For instance, while the PC model may fit the evidence extremely well, PC
only provides metaphysical answers about the mode and not mechanistic
answers about the method in which God created all species. I reiterate a
point I have made several times here, evolution and PC address different
questions.

This is a problem made by those on both sides of the debate. The knee-jerk
association of evolution science with philosophical naturalism is an example
of how those who criticise evolution commit this error.
