   Format: MarkdownItexThanks! One can see more pdfs on [independent.academia.edu/UwePetersen](https://independent.academia.edu/UwePetersen), but there seems to be no good way to link to them.

   Format: MarkdownItexI take it the quote it referring to the fruitful benefit of having a precise mathemetical formalization for otherwise vague and ill-defined notions, quite in the general spirit of approach of, say, the formalization discussed at *[[Aufhebung]]* (even if Petersen is looking into different mathematical tools for this purpose).
