I follow the stance of the Pragmatists who contend that truth is defined as that which is found to be most useful, or delivers the highest utility.But useful doesn't necessarily correspond with true.
Utility is useful in choosing actions or political positions, but belief should be based on one's best perception of truth, regardless of its ramifications.
Abandoning an action or lifestyle is one thing, but shouldn't religious belief be based on absolute, epistemic Truth?
Absolute rubbish! No-one familiar with science believes this, religious or not.
Science is a best guess. It's never infallible, in fact, testing; trying to disprove one's hypotheses, is part of its methodology. Science' theories are always provisional
Where do you come up with this stuff? What do you base this on?
How would science come to such a conclusion? The best it can do is say God is unnecessary to explain the world we see.
And what the heck is a "science minded atheist?" How is one different from a scientifically illiterate atheist, or a science minded non-atheist?
Why this obsession with atheists, anyway?
theories and models are to be judged primarily by their fruits and consequences, not by their origins or their relations to antecedent data or facts. The basic idea is presented metaphorically by James and Dewey, for whom scientific theories are instruments or tools for coping with reality. As Dewey emphasized, the utility of a theory is a matter of its problem-solving power; pragmatic coping must not be equated with what delivers emotional consolation or subjective comfort. What is essential is that theories pay their way in the long run—that they can be relied upon time and again to solve pressing problems and to clear up significant difficulties confronting inquirers. To the extent that a theory functions or “works” practically in this way, it makes sense to keep using it—though we must always allow for the possibility that it will eventually have to be replaced by some theory that works even better.
