Anyway, it's intolerable that no anaphor-- >antecedent relationship can be defined precisely structurally, It may be intolerable, but Lojban was explicitly defined with, umm, pragmatically-based semantics for anaphora (if for no other reason than "pragmatically-based" is the formal embodiment of "let usage decide" - but the real reason is that JCB defined all his anaphora using pragmatic rules - goi was MY addition to allow some sort of unambiguous definition) >and >indeed I don't know any justification for the claim that no'a and >nei are pragmatically defined. The justification is that ALL of Lojban anaphora are pragmatically defined *by intent*, with the exception of the bound variables required by formal logic and specific assignment with goi/cei. >I don't deny that there are certain >vaguenesses such as whether sumti tails constitute a bridi for the >purposes of no'a definition; semantically they should, but >syntactically perhaps not. And pragmatically, it may turn out that the rules may depend on the values thereof, but in some of these cases we actually did make an attempt to think things through a little farther than that, which is why no'a is even in the language (we realized that vo'a was not enough to solve all anaphora back references within a complex bridi). >The antecedent of no'a is a bridi, not a selbri, so the antecedent >should be the mother bridi irrespective of whether the selbri of >that bridi precedes or follows the no'a anaphor.

Ambiguous: What is "the current bridi"? And what does "nei" convey that co'e would not?

You could claim that of all the anaphora. But JCB himself seemed to favor loose definitions of the pragmatically defined cmavo, and having put in a mechanism for exact definition when needed, I am content. lojbab -- lojbab lojbab@lojban.org Bob LeChevalier, President, The Logical Language Group, Inc. 2904 Beau Lane, Fairfax VA 22031-1303 USA 703-385-0273 Artificial language Loglan/Lojban: http://www.lojban.org
