(Re: Beto) ... if you are asking for textbooks that incorporate Wittgenstein in logic and ethics, I'm afraid you won't get much of an answer around here. There aren't enough phil profs on this list (yet.). But I tell you what: I'll send your query over to CHORA to see if they can help. If you find any answers on your own, please post them to the list.
