I think something is being overlooked here, a crucial distinction that is made evident by that passage with the two scientists in discussion. A scientific fact is only as true, albeit in a highly probable sense, as the next observed occurrence, and every scientific hypothesis or theory is open at any time to be rejected or modified. And because of that understanding not even the most single-minded scientists expose themselves to the ridicule of their peers by claiming that naturally occurring phenomena are some form of absolute or certain truth. And yet religious faith does presume that very thing, that God exists is a true belief, that is to say absolute and certain, while allowing no arguments to count against that belief as faith. Theist philosophers always find for the conclusion that God exists from that same premise, which is either given or already held in advance. So belief in God is not a genuine enquiry for it seeks to understand the world only according to pre-conceived notions that are not subject to change, dogma in other words, while scientific discovery can never be constrained in that way.
Many scientists are also believers. Certainly they make enquires. They demand rational
reasons for holding their beliefs.
Some of those reasons can be congruent with scientific facts. Our understanding of scientific theories change but well tested facts do hold up. Einstein's theories find application where Newton's would not - but Newton's still apply and work well for
many applications.
Modern science is very congruent with belief. It always will even though science will advance. Because one of the things you need in order to do science - in order to have it - is and orderly universe. A universe where things are repeatable and you need the expectation that that state of affairs will continue into the future.
Else why bother to do the work?
So the fact that the universe reveals itself to be orderly - that the laws of physics can be discovered at all , that math yields insights at all are facts that are congruent with faith.
Science yields discoveries - well tested ideas that stand up to scrutiny - that provide intimations of God's existence.
That carbon can only be formed in stars and that under very exacting conditions is a fact that is not likely to change. The forces of gravity and electromagnetism and the strong and weak nuclear forces have to pretty much be what they are - the constants
or formulas that describe those forces and the way they interact are not likely to change or the ideas of the way the molecules have to interact - but there is an amazing process there - just one example.
But these are intimations of a Creator and it is rational to accept them as such. maybe some day we will have an even better understanding of this but that understanding would likely only be more of an intimation rather than otherwise.
Some might be historical reasons. Thinking about the historicity of the resurrection of Christ. That is a rational inquiry. The facts have to be explainable in an intellectually satisfying way.
Some reasons are personal - come by way of personal experience - to the believer there is a relationship - an interaction - that provides rational belief to him or her.
I believe I have experienced providential care over the course of my life, for instance.
On the battlefield when I was in Vietnam. How I fell into my career.
These involved answered prayer and an improbable chain of events.
So this sense of being cared for and the way life progressed in a fairly satisfactory way - sometimes when I would have made other choices had I been able to - these become reasons that support my faith.
I have other reasons - that the Gospels ring true for me. Prophecies about the nation
of Israel that I see coming true today. the statements were made in the Old Testament - the people would be dispersed fro disobedience- but then later restored to the land - which though it had become a desert would be made to flourish.
Those are recorded in the Dead Sea Manuscripts so we know they are at least that old - yet they are coming true today. There is a congruence there.
These are not trivial reasons - they may not prove anything to you - they can be explained away. If you adopt a position that says the supernatural does not exist, you will discount them.
But then may only be holding on to your faith - your basics philosophical beliefs - in the dogmatic fashion you accuse believers of doing.
BTW , I think many individual believers would abandon their faith were it not intellectually satisfying and plausible to hold it. Some may not but I think many would.
There is a difference between having a plausible faith - one where several different
kinds of reasons seem to be congruent and has a breadth of explanatory power and works in the life of an individual and holding a faith or belief that does not have rational support.
