srsly? back when I was publishing on habermas, i did a massive inquiry as to which was the ultimately correct approach: habermas' or habermas's. it bugged me that i could never find a definitive answer.
so habermas' is the possessive plural of haberma?
?
i never got an answer indicating one or the other. publishers, editors, proofreaders, habermas scholars, and the toerh books and articles about Haberma all did it according to their own preferred style guide. *shrug*
