Why?  English idiom, which we are forced to use for the English
translations.  In the specific example, size is also a factor.  Bean was
listed in the vocabulary in contrast to seed, and except for farmers, we
(English speakers) generally tend to identify seeds as collections of
units, rather than as quantities.  You cook a cup of rice, but you plant
seeds individually.

Where a word could be interpreted either as a mass noun or a count noun,
I chose based on the words I was contrasting it with, for style of
definition.  Bean matched seed, the various grains matched each other,
etc.  Deer, a classic individual mass distinction since the plural is
identical to the singular, is written as a count noun because other
animals are also count nouns.

There is no way to clearly talk about English mass nouns as if they were
count nouns, that does not dictate the unit size - and as we have seen
with djacu, there can be clear disagreement with some of these as to
what the unit size is.

You can argue that the unit of djacu should be molecules, but some
specific properties of water do not apply to small numbers of molecules,
some cultures don't know what a molecule is (Lojban needs to be able to
translate Ancient Egyptian discussions of water, and they certainly
weren't talking about molecules.)  And there isn't much sense in a
"molecule of food" (and there are some things like festi/waste, poisons
and germ-caused diseases where individual molecules don't have the
wastage, poison or disease-causing effect that a larger collection of
units might.

What is "accurate"?  Are the Trobriand Islanders inaccurate when they
view all rabbits as the same thing?  Accurate means that it reflects the
speaker's concept.  I rarely think of molecules when I talk of water, so
to make my words mean or imply molecules is NOT accurate.

The scientific world-view is a metaphysical bias just as others are.  We
"lo dembi/rismi/djacu/canre/cidja all refer to some kind of countable
portions of the respective substances.  And loi
dembi/rismi/djacu/canre/cidja all refer to mass portions of the same
substances.  The countable units of some substances, like festi, may
themselves be mass units "lei festi", or in the case of water, lei
djacu.  If you go into a restaurant with 3 people and ask for 3 waters,
you don't want 3 molecules of water, nor can you specify the number of
molecules you want.

We need to enable scientific thought, but we must not force it.  By the
way, can someone accurately define a molecule/unit of thought?

Another problem is that very seldom are statements about macroscopic
things really statements about particular atoms or molecules.  I see
shades of your fuzzy logic ship here:  when I drink a glass of water, it
is quite safe to say that the molecules I ingest are not precisely the
molecules that were in the glass when I picked it up.  Liquid/gas
dynamics would have cause some exchange.  So how many molecules did I
actually drink?  Do we include the ones that had evaporated off the
surface and mixed with nearby air, but were inhaled when I swallowed?
But then, do we also include those molecules that were in the same air
before evaporation?

The atomic model may explain something about what water is, but it is
not necessarily true that statements about water are statements about
specific (or definite) countable molecules.  At least not if you really
want "accuracy".

No.  Because not everything is necessarily atomic/quanta, and we cannot
clearly say we know what things are or are not.  The atomic theory is
merely another way of looking at things.

The quest for scientific precision almost destroyed Loglan when it first
went public.  Early articles in The Loglanist went on endlessly in great
analytical detail about color words having to be specified as additive,
subtractive, etc.  The places of "color" were specified as saturation
and hue - that sort of thing.  But when I talk about what color
something is, I haven't the vaguest idea how that color might be
described analytically - the analytic scientific concept is NOT the
human concept.

This is one case where English does have words that clearly distinguish
the different senses.  The gismu English-definitions weren't trying to
come up with strained English forms that cover the individual and the
mass.

But if you avoid English or other metaphysical bias, every single
predicate needs to be describable in units or quanta.  So if a units
place is necessary on any given predicate, you can specify it with a BAI
place built from ci'u or tela'i.  Or you can make a tanru/lujvo using
selci/dirgo etc., as appropriate.

No.  I think the problem here is that you were talking about lei and loi
which are both cmavo used for masses, but implying that you thought of
lei in terms of molecules.  I think that since you were talking about
masses/individual molecules, your probably meant lei/le or loi/lo as the
distinction.

On the other hand, there was discussion about calling for a taxi a while
back (before the "any" discussion got started, though it is probably
related).  And both we and JCB's group independently decided the same
thing - that this was "loi {taksi}".

It is also possible that (a portion of) the mass fits the x1 and yet
none the components do individally.

Well, it COULD be a molecule of water, but only in some pretty
constrained circumstances.
