To: Lojban List Content-Length: 634 Lines: 20 Message-ID: Consider the following sentence: what is its truth value? 1) li vo na'e sumji li re li re On the "na'e entails na" view, this means "4 is not the sum of 2 and 2" and is false. On the other (and/djan) view, it means "4 is a non-sum of 2 and 2" and is true, since 4 is a product (which is not a sum) of 2 and 2. On the other hand, 2) na'ebo li vo sumji li re li re Other than 4 is the sum of 2 and 2 is false on any view, and likewise if you move the "na'ebo" to any of the other sumti. -- John Cowan http://www.ccil.org/~cowan cowan@ccil.org e'osai ko sarji la lojban
