    Lojbab:
    These presuppositions sound like what we have been meaning by the word
    "veridical" when defining "lo".

Hmm... how do I `draw a fish'?   First the easy case:

    .i mi ba'o citka lo finpe
    I am in the aftermath of
    eating
    one or more of all the veridical fish
    in the current universe of discourse.

Yes, the fish is presupposed to exist or have existed.

Now the hard case:

    .i mi ba'o pixra finti lo finpe
    I am in the aftermath of
    illustration type-of authoring
    one or more of all the veridical fish
    in the current universe of discourse.

Hmmm...  interesting ... does {lo finpe} refer to a fish or to a
picture of a fish?   Is this utterance meaningful?

Or should I say:

    .i mi ba'o finti lo pixra be lo finpe
    I am in the aftermath of
    authoring
    one or more of all the veridical pictures of
    one or more of all the veridical fish
    in the current universe of discourse.

This utterance presupposes a real drawing of a real fish.
No problem.

How about:

    .i mi ba'o xraci'a lo finpe
    I am in the aftermath of
    drawing
    one or more of all the veridical fish
    in the current universe of discourse.

I cannot decide whether the x2 of {xraci'a}  is what the drawing is
about, in which case this utterance is OK, or whether it is what is
drawn, in which case the utterance should be:

    .i mi ba'o xraci'a lo pixra be lo finpe
