I’ll admit I don’t know much about postmodern academic discourse; I only hear about it when it gets so “bad” that people complain about it, so I think I am getting a very skewed sample (cf. the Sokal affair - Alan Sokal is a physicist, BTW).
I have, however, had some exposure to more old-fashioned kinds of academic discourse in the humanities. And I’ve even listened to a theologian lecturing about the role of the Orpheus myth throughout European culture.
I find that there is a consistent difference in the use of language between the natural sciences and the humanities - at least here in Austria. The natural scientists use language purely as a tool to convey facts; they are not afraid to use terms opaque to laypeople, but all needless complexity is purely accidental.
In the humanities, however, there are many people who view the artful use of language as an end in itself. They do not put “simplicity” at the top of their style advice. They go for beauty instead.
The electrical engineering course notes I drudged through in my first year at university was one negative example - the sentence structures were so boringly and repetitively simple that I found it very hard to concentrate on the text while reading.
On the other side I’ve seen overcomplex humanities texts that hide severe flaws in reasoning by showing off the author’s mastery of remotely relevant Latin poetry in a deeply nested aside at just the right time.
Now the good professors won’t obscure anything with their language; but a professor of philosophy, theology or ancient history in Austria will just expect their listeners to be able to understand a three-level nested German sentence with the occasional Latin terms without overly taxing their minds.
Some very smart people with a purely scientific/technical education will lack the practice and find it annoying at first, but a high school graduate from a humanities-focused school won’t have any trouble.
Are people in post-modern academia in the English-speaking world doing something similar?
… which is also one of the reasons why I dislike “The Elements of Style”. I enjoy the artful use of language. The constant insistence on “simplicity”, on omitting everything “needless” seems to me a cultural phenomenon of the English-speaking world that has been slowly seeping into other cultures, and I don’t like that trend.
Call me when LISP has a decent type system.
