Re: The "problem" with external quantifiers



Numerical quantifiers can be expressed using the usual quantifiers
and identity.  "I ate 3 apples" need not involve any reference to
sets.  For practical reasons such quantifiers should be primitive
items in a language like Lojban!  However, one doesn't go far
in discourse about numbers before one wants to treat them as objects
themselves, and as soon as one does this one needs sets (or
higher-order predicates).
