When some field is afflicted with deep and persistent philosophical conflicts, this isn't necessarily a sign that one of the sides is right and the other is just being silly. It might be a sign that some crucial unifying insight is waiting several steps ahead.

I agree with this. Such ongoing disputes in a field are often signs of a shared false premise leading to the false alternative as frequentist -v- bayesian. The "unifying insight" comes from identifying and correcting the false premise. Finding it requires examining the field at a more fundamental level. This was my point in my first post to LW in the "Unspeakable Morality" thread when I wrote...

And hopefully the whole frequentist -v- bayesian dichotomy-debate will turn out not to have a false premise behind it. Of this I am not sure.

I am just learning Bayesian ideas but I am learning it with the caveat that it might have accepted a false premise that is also behind Frequentist ideas. Good fun!
