[lojban] "to think that ..."

[tijlan <jbotijlan@gmail.com>]

I was reading an article on finitary relation

http://en.wikipedia.org/wiki/Finitary_relation

which gives this sentence

"X thinks that Y likes Z"

as an example of ternary (three-argument) relation. That isn't how "to
think that ..." is commonly represented with a Lojban selbri:

"X jinvi lo du'u Y nelci Z"

In this bridi, X relates only indirectly to both Y and Z as parts of
another single abstract argument ("lo du'u ..."). Excluding the
implicit x3 and x4 of "jinvi", this expression is binary, not ternary.
I wonder if one of the approaches is logically more preferrable than
the other in making the same statement. Or do they make logically
different statements?
