Yes, it's entitled "Good and Real." The shadowy cabal behind LessWrong wrote it under one of their other pseudonyms, "Gary Drescher."
(Note: this is not actually true. But Good and Real recapitulates most of the points you'll see in the philosophy-related sequences, with less focus on the basics and more on elaborating philosophical arguments. If this is the content you want to share, it might be a good choice.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
