So English "not A, B and C" can mean "It is not the case that each of A,B,C is the case" or "For each x, where x is one of A,B,C, it is not the case that x is the case". Unless it has been fixed by recent BPFK action, Lojban has *exactly the same ambiguity* with regard to logical scope between elements that are not explicitly prenexed.Show me an example please.
"su'o broda ro brode cu brodi" "na ku a bu e by e cy cu broda" Ten years ago these were ambiguous. Xorxes proposed a rule that items in higher clauses have scope over items in lower clauses (i.e. that items export to the prenex of the localmost clause) and that when two items are in the same clause, the leftward element has scope over the rightward. (It's a shame to have to 'pollute' the purely hierarchical structure of logical form with left-to-right order of forms, but it's by far the simplest way to rescue Lojban in its (then) current state. Perhaps the BPFK has made xorxes's rule official, in which case I wonder what happened to the rule about the scope of selbri tcita "na", and to the scope of selbri tcita in general.) --And. -- You received this message because you are subscribed to the Google Groups "lojban" group.
