I have to wonder at the fairly frequent comments from people on DU pronouncing that religious belief is
obviously illogical, irrational, and lacking in intellectual respectability, etc.
One reason for my saying this is that just off the top of my head, I can think of two of the most important logicians of the 20th century who've been religious believers. That, of course, doesn't prove that religious belief is true or logical or rational, and of course there are other logicians (Quine is one) who don't have religious beliefs.
So this is not an argument from authority. Lots of people believe that we should defer to the scientific community--our deference doesn't prove that science is true, of course. And we don't personally carry out all scientific experiments ourselves, and not all scientists agree among themselves about everthing. But it's a mark of the
intellectual respectability of a scientific belief that at least some leading scientists hold to it, and are prepared to argue for it. Their beliefs may be wrong, of course. But they're considered intellectually respectable, just for that reason.
Example: I don't really grasp the intricacies of string theory. But I think I know that string theory is intellectually respectable, because I know that at least some leading theoretical physicists believe in it. String theory might be completely wrong, for all I know. But it is, currently, intellectually respectable to talk about strings, and multiple spatial dimensions, and so on.
So how intellectually respectable is religious belief?
Godel is arguably the greatest logician of all time, and probably the most famous (given his celebrated Incompleteness Theorems). He was also a religious believer and thought that one could prove the existence of God by logical argument....
Kurt Gödel is best known to mathematicians and the general public for his celebrated incompleteness theorems. Physicists also know his famous cosmological model in which time-like lines close back on themselves so that the distance past and the distant future are one and the same. What is less well known is the fact that Gödel has sketched a revised version of Anselm's traditional ontological argument for the existence of God.
How does a mathematician get mixed up in the God-business? Gödel was a mystic, whose mathematical research exemplified a philosophical stance akin to the Neo-Platonics. In this respect, Gödel had as much in common with the medieval theologians and philosophers as the twentieth-century mathematicians who pioneered the theory of computation and modern computer science. However, a deeper reason for Gödel's contribution to the ontological argument is that the most sophisticated versions of the ontological argument are nowadays written in terms of modal logic, a branch of logic that was familiar to the medieval scholastics, and axiomatized by C. I. Lewis (not to be confused with C. S. Lewis, or C. Day Lewis for that matter). It turns out that modal logic is not only a useful language in which to discuss God, it is also a useful language for proof theory, the study of what can and cannot be proved in mathematical systems of deduction. Issues of completeness of mathematical systems, the independence of axioms from other axioms, and issue of the consistency of formal mathematical systems are all part of proof theory.A lot more

Michael Dummett is a very eminent English philosopher and logician, and is especially well-known for his important work on German mathematician and logician Gottlob Frege, who himself can be regarded as the founder of modern logic. From 1979 to 1992 Dummett held the post of Wykeham Professor of Logic at Oxford, arguably the most prestigious professorial chair of logic in the world. Dummett is also known as a very devout and religiously conservative Roman Catholic, and a fierce opponent of racism.
...Although he was educated within the traditions of the Anglican Church at Winchester, by the age of 13 he regarded himself as an atheist. In 1944 however, he was received into the Roman Catholic Church, and he remains a practising Catholic.....A lot more

A leading, and well-known religious believer who, prior to retirement, was a theoretical physicist at Cambridge is John Polkinghorne. More about him
here.
I could go on to produce many leading lights in physics, chemistry, biology, philosophy, logic, mathematics, and other fields who are also religious believers.
What I conclude from this evidence is not that religious belief must be true, or even that it's rational, but simply that it's impossible to take seriously the claim that having religious beliefs is an
obvious sign of the holder's intellectual deficiency or irrationality or illogicality. The same conclusion would hold with regard to atheists and atheism of course, for similar reasons. But that's the point---the conclusion holds for both cases. Theism and atheism are
both intellectually respectable beliefs.
On the other hand, I'm struggling to think of any major intellectual figures in the sciences and humanities in the post-Darwinian era who have been Biblical fundamentalists. There may be some, but if there are, such cases are certainly not common. Far more common, however, are the cases of very eminent intellectually gifted people who are theists.
Of course, one doesn't decide the truth of a belief by conducting a poll of even intelligent people's attitudes to it. But I think that
is, roughly, how we come to judgements about
intellectual respectability---by seeing that among leading figures in fields that pertain to that belief, or at least in fields that have some potentially fairly important conceptual connections to the belief in question, it is fairly commonly held.
'Fairly commonly held' doesn't have to mean a majority. For example, I take it that 'hidden variables' interpretations of quantum mechanics, though not widely accepted within the physics community, are nonetheless intellectually respectable. (It's worth noting that 'hidden variables' interpretations are consistent with the data. It is extra-experimental considerations that persuade the majority of physicists not to accept them).
