While traveling I saw a review for Alvin Plantinga new book “Where the Conflict Really Lies: Science, Religion, and Naturalism.”   Checking out the comments on Amazon.com, I noticed a discussion, and decided to jump in.   Here are my replies, with links back to the notes I am replying to. The passages in quotes are taken from the note to which I am responding.

In reply to Paul L. LaClair post:

LaClair,

I was checking out this book and started following this discussion. I found your comment to calcidius that “Most people who say they believe in a god admit they have to rely on “faith,” since they can’t prove it” as particularly problematic for the following reasons,

“Most people” — the fallacy of an appeal to the people. What “most people” say is irrelevant to the truth of a proposition, particularly in the discussion here as “most people” do not think deeply about the philosophical underpinning of their beliefs.

Then there is the contrast of faith and proof. Proof is a very vague and ultimately subjective concept. What does and does not constitute proof varies from situation to situation, and from person to person. In its general sense, proof is simply the level of evidence needed to conclude that something is true.

Faith, on the other hand, is not a basis for belief, but a reliance on a belief that causes someone to act. In the realm of religion, a person can intellectually believe that God exists, but if that believe has no impact on their life, they do not have faith. However faith is not limited just to religion. Everyone has faith in what they believe, and they structures their lives accordingly, even the scientific naturalist.

While it is possible to have a blind faith in the absence of, or even counter to, the evidence, not all faith is blind. Faith can be supported by the evidence. An engineer could calculate that a bridge will support him, but it is faith in his calculations that allows him to cross the bride.

This is where the contrast of faith with proof is so problematic. It is one of the reasons I rarely talk about proof, preferring rather just to speak of evidence. Is there proof for god? While this would depend on the standard of proof being used, for simplicity sake, I will say no. But the absence of proof should not be taken to mean the absence of evidence, and I do believe that there is evidence for God. In fact, I believe that a theistic worldview has the least problems of all the various ways of understanding reality, including scientific naturalism, and thus is the best explanation.

You can see this difference in your statements such as,

“Good scientists hold many of the questions open, and then make judgments about which avenues of inquiry are most likely to be productive. A reasonable scientist does not spend her time trying to figure out whether ‘God did it’”

But what is “reasonable” and “most likely to be productive” will depend strongly on one’s world view. Thus for example, when considering questions such as the origin of the universe, or the beginning of life, should a scientist be seeking to discover what happened, or should they limit themselves only to natural explanation for these questions? Scientific naturalism argues the latter.
