But under the standard semantics of Lojban events, they exist
(i.e. da nu broda is true) as long as the obvious presuppositions
are met: "da nu do jbena ricfu" is true in any world where you exist
and the notion "born rich" makes any sense at all.  To assert that
an event actually occurs, viz. that you were born rich, we have
to say "lo nu do jbena ricfu cu fasnu".

Explicit means to express such a distinction are problematic, however,
for the same reason that the explicit "truth" and "falsehood" attitudinals
are: they are most needed when they can be least believed.

Ray Smullyan discusses a related point in his god-and-mortal dialogue,
where the god (God? can't tell from the typography) says "Look, if you
were to ask me 'Do you really exist?' and I answered either yes or no,
what would that actually prove either way?  Absolutely nothing!"
(paraphrased).

After accepting the distinction between the fictional and the potential,
here you are blurring it again.

So we do, but we talk about them with the accents of truth.

*Potentially* manifest.
