Mark will find Lojban familiar - we have all the tenses needed to make all the Sanskrit distinctions, and a few more besides. There IS a semantic distinction between aorist past, the simple past of English, and perfect. But not in all sentences. Take the English sentence "I read the book". The simple past here implies that you read the book sometime in the past, and are not reading it now. The perfect past "I have read the book." says the same thing, but also explicitly implies that the reading-event was completed: you finished the book. Aorist is a past that says nothing at all about either completion or whether the action continues into the present. English is of course irregular. "He was alive" implies that he isn't anymore, as well as "He was alive 5 minutes ago". "He was alive during World War II" makes no such implication, because the added information suggests an alternate semantics for 'alive' than mere breathing: experienced. Lojban 'simple' tense is aorist. mi pu tcidu le cukta I aorist-past read the book says that at some time in the past you were reading the book, not whether you finished it, and not whether you might still be reading it. Similarly "mi pu jmive" (I was alive) makes no statement about whether I still am (ignoring the fact that I'm the one stating this %^). To match the English simple past clearly and exactly, you must say mi pujecanai tcidu le cukta I past-and-not-present read the book and to clearly say that the book-reading was completed, you get mi ba'o tcidu le cukta I am-in-the-aftermath-of-the-normal-completion-of reading the book. or you must use the predicate 'mulno'. In most cases, the English distinction is unimportant - we use simple past rely on context to imply whether the book was completed. Similarly in Lojban we tend to use no tense or the simple past, adding in the other forms only when it is important to say whether you ares till reading it or have completed it. In English of course, you in effect violate the normal tense interpretation to imply the aorist situation. The aorist Lojban does not exclude the present tense. It is an oversimplification for your Sanskrit professor to say that these tenses made no difference. They did (though it is possible that they were so rare and complicated as to be oft misused). Similarly with the passive voice, which is considered pretentious in English. It changes emphasis, which can be important. John Parks-Clifford (pc) has studied Indian logic in some depth, and he notes that those enormously complex tenses and grammatical constructs sometimes do make a difference in truth. To us nowadays, though, the difference might be akin to arguments about angels dancing on pins. ---- lojbab = Bob LeChevalier, President, The Logical Language Group, Inc. 2904 Beau Lane, Fairfax VA 22031-1303 USA 703-385-0273 lojbab@grebyn.com For information about Lojban, please provide a snail-post address to me via mail or phone.
