I already asked you two days ago to explain your notation, please.
Does this mean something like "forall x : Green(x).(seek(I, x))"
or "A(x) => Green(x) => seek(I, x)" or "forall x. Green(x) => seek(I, x)"
...

I'm not sure I like that "goal driven" analysis of seek.
Especially, mixing up quantifiers and goal constraints is rather confusing.

What your "Ax Greenx I seek x" is _supposed_ to mean, I think, is the following.

There exists a goal G1 which I have in mind, such that for all green things
it is true that if I have such a green object, the goal G1 is fulfilled.

I very much prefer the analysis I described in my last mail,
because if you try to apply quantifiers here, you have to be explicit about
the existential goal quantification.
Else you could end up searching for _all_ green things:

forall x. there exists g. have(I, x) => satisfied(g)

(I just invented the "satisfied" for the lack of a better notation)

Again, I prefer to say that {mi sisku da poi crino} adds an
object to the universe of discourse which satisfies {crino} and can map
to a number of physical objects, therefore creating the feeling of
a restricted universal quantification.

We do this in NatLangs as well: "I'm looking for a shirt.",
"I'm searching for something green.", "Ich suche eine Kuh.",
"Je cherche une vache.", ...

Just to point this out again: This is an analysis which I proposed in
my last mail and which I never directly read about anywhere. Therefore,
I'm still waiting for criticism and comments.

I don't really get, what you try to point out here.
