So anyone — excepting legal Others in various, trivial settings — who writes/says: “In Judaism, we have a concept… But we also have another concept…” has no concept of anything, least of all how foolish they appear.
To “immanentize the eschaton” we have this little-known, ahh, “concept” you may have once heard about. It’s called halacha, or Jewish law.
Whenever I see this ridiculous phrase, I rip/skip/flip/blip the piece immediately.
(Of course, Mussar\Chassidus books abuse “Concepts”, too, but they, at least, know how to finesse it.)
