John Clifford Posted about 2 years ago The viability of implementing a logically constructed Language. Namely Lojban. To clarify a bit. 1. The language created by James Cooke Browne is Loglan, which is still supported by The Loglan Institute. Lojban is a revised version created by the Logical Language Group, Robert LeChevalier, Founder and President. The two have diverged significantly within the same broad framework, but both have active followers. 2. The any non-trivial claim that language has a profound effect on speakers is contentious (the Sapir Whorf Hypothesis, itself never clearly formulated). The suggestion that a language based on the principles of Logic (whatever they may be) will say something significant about this question was the original purpose behind Loglan, but the experiments were never carried through. 3. Both Loglan and Lojban exist, the one for 58 years in various forms, the other 24 or so, and both are. in some sense, based on the principles of logic, so the issue of viability seemed settled in the affirmative, unless there are further details that are not mentioned. 4. The characterizations of Lojban are basically correct but perhaps misleading (and are, for the most part, not unique). a. Lojban has developed its own culture (related largely to Western computer scientists) and is hardly neutral. b. Lojban grammar is unambiguous by fiat and the grammar that guarantees lack of ambiguity is not proven to tie in with principles of Logic. c. No one reports Lojban to be easy to lean (this may be partly due to old-fashioned learning tools, now being replaced):its vocabulary is totally unfamiliar (despite claims to the contrary), its basic sentence structure is different from that of familiar languages, lack both prepositions and cases, which latter accounts for its regularity -- there is nothing to change. d. Lojban culture goes for precision and the requirement to get things just right has proven to be a hindrance rather than a help for creativity -- constatnly going back to check delays going forward. But it still functions.
