Okay. Irrespective of how you intepret {finpe je mirli}:

It is true exactly of things that are simultaneously both fish and deer, the intersection of the two sets (null in this world and, I suspect, most others).  The herd of fish and deer together, the union of the two sets, is {finpe je mirli} true of things that are one or the other (or both-- sure, sure!).

<1. Would you say that {lo finpe .e lo mirli cu finpe je mirli}?>

Factually?  No.  I'd say {no da finpe je mirli}  To be sure, if anythiing were in this set, it would be a fish and a deer.

<2a. If so, since .e is rather well defined, would you then accept that
{lo finpe cu finpe je mirli}?>

Yes, IF.  This is NOT the white horse problem.  But, in fact no.

<2b. If not, what does {lo finpe je mirli} refer to?>
Some member(s) of the set of things that are simultaneously both fish and deer.  But there aren't any, so it is a falsifying _expression_ (makes atomic sentences in which it occurs false, or drives the conversation into another --very strange -- world.
