lojbab:

Sure, that's one. I also discussed fuzzy functions in my reply to Jorge's
suggestion that mathematical functions are non-fuzzy, my point being that
Taylor Series expansions of functions may be thought of as fuzzy, with the
Riemann remainder representing the fuzz.
lojbab:
>This is why I don't really like the "xi" convention.
Agreed. Does lojbab consider this use of "xi" to be idiomatic? I'm becoming
very interested in the cmavo; they are more (and less) than they appear!
The terse definitions given seem *very* misleading in some cases.

Don't know what a "sei" metalinguistic phrase is. Do you mean the rafsi for
<sepli> or <sehi>, the cmavo for self-directed?

Neither one is very good. I was using <kerfa> in the sense of "fur" -- the
vague boundary between a critter and his environment. I consider both
<kerfa> and <murse> to be flawed translations of the "fuzzy logic" sense
of "fuzzy" for the same reason: they are both concrete, when what is needed
is something abstract. <ka murse> doesn't fly either--what is it about
<murse> that is being abstracted? Surely fuzziness is not the first thing
that comes to mind. As metaphors, maybe that's the best lojban can do.

Agreed.
There is still the fuhivla: <logyfuzis>

Been there, done that, and rejected it. Unless I misinferred a design
principle of the language. I thought that the lojban designers were intent
on doubling the number of necessary gismu by using the "antonymal
language-design buddy system":
<linto> :: <tilju> for weight
<clani> :: <tordu> for length in longest dimension
<ganra> :: <jarki> for length in the second longest dimension
<rotsu> :: <cinla> for length in shortest dimension
Seems <na clani> wasn't good enough. No doubt they did this so that they
could fill gismu space with culturally neutral debris and so they could
later complain about there being too many gismu. :-) I searched high and
low for an antonymal buddy for <satci> but came up empty. As the gismu
creating is semifrozen, I searched for alternatives.
Besides, don't you mean <ka na satci kei>? (Has a rather doubleplusungood
quality to it.) Rather lame that lojbaners talk about vagueness in terms of
not-preciseness. So are we stuck with a fuhivla, <lojyfuzi>?. Somebody
suggested using <klani> to construct fuzzy lujvo, but I couldn't figure out
why.

I used <ckilu> for Guttman scales extensively in my previous postings.

>Sheesh!
Or apparently talk about fuzzy logic at all, as you have determined that
fuzzy logic is not important! Slow down, Logical Bob :-)
The situation regarding fuzziness appears unsatisfactory.
Next: Why fuzziness matters.
