If you can count them, then you can delimit them.

I think that is not the prevailing understanding of masses. Replace "loss" by "irrelevance", and you have something closer. > Or shall we say that any possible manifestation of the mass properties is a > putative member. I don't understand. Obviously this works for loi djacu, but that's because the criteria that individuate lo djacu are undefined. But what about loi prenu? > >The evolution I envision is one of usage.

Surely in the sense of "speaker" that is normal in linguistics there are many speakers of Lojban, if Nick is one. And Nick hasn't been saying anything on this list since 1994 or so! My view, based on experience, is that if Jorge says something's useful then it is, and if he says it isn't then it isn't! > >My point is that the parts of the grammar that are not used > >in everyday conversation don't really belong in the language. > > None of Lojban is used in everyday conversation. Change it to "the parts of the grammar that would not be needed to render in Lojban everyday conversation in natlangs don't really belong in the language", & Jorge's point stands. --And.
