3.323 -- In the language of everyday life it very often happens that the same word signifies in two different ways -- and therefore belongs to two different symbols -- or that two words, which signify in different ways, are apparently applied in the same way in the proposition.Thus the word "is" appears as the copula, as the sign of equality, and as the _expression_ of existence; "to exist" as an intransitive verb like "to go"; "identical" as an adjective; we speak of something but also of the fact of something happening.
3.325 -- In order to avoid these errors, we must employ a symbolism which exlucdes them, by not applying the same sign in different symbols and by not applying signs in the same way which signify in different ways. A symbolism, that is to say, which obeys the rules of logical grammar -- of logical syntax.
Can Lojban really resolve all problems figured in 3.323? Can Lojban be this symbolism which obeys the rules of logical grammar -- of logical syntax?
If so, maybe we can suppose that we can map each Lojban proposition to a fact, and that there exists an correspondence between Lojban language and reality.
