A second matter was the third place of mukti (and some other of the words in
this collection?) event x1 motivates event x2 in volition of x3. Since x2 is
presumably an even in which the agent is the one who's volition is involved,
x3 repeats the subject of the description in x2, usually at least. These
place structures are baselined and immutable until some future date, but we
might consider reconsidering these cases at that date. They seem to arise
from English (etc., but we know what most of the founding members spoke)
expressions A motivates B to do C, which is taken to be a 3-place relation,
even though most good grammars of English (etc.) recognize it as only
2-place, the second place being an infinitive sentence "B to do C". Of
course, both pieces function separately A motivates B, A motivates Cing: the
raised subject and the suppressed subject respectively. At least, until
reconsideration, we might well drop the use of the thrid place.
And back to the original problem. I used to advocate a predicate "x1 brings
it about that event x2 by doing event x3." I now notice that, except
rhetorically, this is another case of duplicating the subject of an event
description. There is, however, no obvious predicate in Lojban that does
this in the properly vague way, so that the original sentence is still
untranslatable in its full obscurity.
