The OP started with a quote, that began:

I take that as indicating that the source was anonymous. It is my intention, in this post, to question that opening quote. It begins:
A literalist imagination--or lack of imagination--pervades contemporary culture.
To me, this seems incorrect. Surely there is some literalism, but it does not seem pervasive. Literalism is perhaps most pronounced in the creationist literalism of some fundamentalist religious groups. But that kind of literalism appears to be a relatively modern invention.
There is some literalism elsewhere, judicial literalism being one example. But even there, I don't see a lot of it. Courts mainly seem to emphasize intentions of the law makers over a literalist rendering of the wording of the statutes. There is some literalism in bureaucracies, but that was always so. It is of the nature of bureaucracy. Yet even there, I do not find it a pronounced problem.
One of the more dubious successes of modern science--and of its attendant spirits technology, historiography and mathematics--is the suffusion of intellectual life with a prosaic and pedantic mindset.
This statement surprises me, for it is far from my experience. By its nature, mathematics is pedantic with respect to formal expression. But most mathematicians are informal and far from pedantic in non-mathematical ordinary life. Scientists overall, are mostly pragmatic, and that makes them far from pedantic. They are fussy about methodology, not about linguistic expression. To be sure, they are careful when discussing methodology, and perhaps that can seem pedantic. But I don't see any carry over to pedantry in their ordinary lives.
One may observe this feature in almost any college classroom, not only in religious studies, but within the humanities in general.
Now there's a switch. After attributing the problem to science, the anonymous author seems to say that it is to be found mainly in the humanities.
I don't spend a lot of time in the humanities classroom, so it is hard to comment on this. I do sometimes wonder if the humanities are trying too hard to emulate the rigorous standards of the sciences, when they attempt to evaluate scholarly work in their own fields. But I have never thought the problem serious enough to be considered pervasive.
Students have difficulty in thinking, feeling and expressing themselves symbolically.
It has always been so. But why not say it as "Students have difficulty in thinking, feeling and expressing themselves." What does that word "symbolically" add? These are, after all, students. They are still learning. We should not expect them to be professionals at self-expression. That might be our aim for them by the time they graduate, but it is not our expectation of them as students.
