Do we? Need to be more careful?
The issue in theological debates is whether we NEED the idea of God to explain anything. I think the principle works pretty well as a back drop.
When we're talking about God as an explanation, the idea is going to come up.
Even if it weren't explicitly brought up, it would still be an elephant in the room in such a discussion.
Personally, I think the issue of whether we NEED God to explain various levels of things is superfluous for most of what we want to know about our universe; we also have to recognize that even IF there was a God that Created the Universe, we have to ask ourselves: can we indeed recognize the level or extent to which
we are actually able to discern God's influence and/or causative acts in the fabric of the reality in which we find ourselves? Unlike other Christians, I would say that (in line with
Methodological Naturalism),
it is problematic to do so.
However, there are those on the others side of this debate, made up of both atheists and Christians, who who hold a particular Ontological assertion that we
can discern the signs in the universe that tell of God's interaction, or of what seems to be a clear lack thereof, such as is proffered by both Philosophical Naturalists [Richard Dawkins] on the one side, and proponents of Intelligent Design [Michael Behe] on the other. Both of these parties think we are able to discern whether or not there are
scientific signs of God's handiwork in the universe.
So, it is the way in which Occam's Razor comes to play in the middle of this debate. The truth is, William of Ockham's approach in describing how conceptualizations, labels, explanations, and language play a part in our understanding of existence in our universe is more in line conceptually with Methodological Naturalism than it is with Philosophical Naturalism. At least, that is my contention.......
And who has the Burden of Proof in dealing with and explaining God and a possible connection to our universe?......
no one really, because God isn't the kind of entity that can be controlled for experimentally, or comprehensively understood rationally, which is what Ockham would say.
