In the 19th century it was unremarkable for a scholar to publish his thesis or book in Latin. Many did so. After all, to obtain admittance to a university every student had to demonstrate competence in Latin. So every scholar should be able to read and write in Latin as easily as his native language.
Let us compare this with the situation today. On the one hand, most students couldn’t compose a verse in Latin to save their lives. On the other hand, academics are forced to learn several other languages in order to study the academic literature. Every respectable modern academic must have a good reading knowledge of English, French, German and Italian.
The standard of too many anglophone PhD theses suggests to me that most of the students writing know only one language, and that English. No doubt when they collect their PhD certificate and obtain a teaching post their command of languages improves instantly.
Wouldn’t it be easier just to learn Latin really well?
