They certainly do carry over to the variable cases, even in the empty universe case. {ro da broda} is tautologically true in an empty universe in my system, just like {me'iro da broda} is tautologically true in your system, but false in mine. >The middle equivalence and the peripheral one hold >for both systems, of course (they are just contadiction). the first and >third have a long history (obversion) but have always been (quite >reasonably) >suspect.

I think (A-E-I+O+) is simpler, and I can get all cases as well, of course. mu'o mi'e xorxes _________________________________________________________________ The new MSN 8: advanced junk mail protection and 2 months FREE* http://join.msn.com/?page=features/junkmail
