- So would I, actually. It is possible to use stratification to avert
- semantic paradoxes by making quotation a type-raising operation; it is
- only needed if one wants a language with names for all objects in NFU.
- If one uses more modest linguistic machinery, one uses the same
- solutions to semantic paradoxes as in the usual set theory.

-
- This is confused. Stratification is a tactic for determining which
- predicates can be reified; it is ony relevant if one has the project
- of reifying at least some predicates in mind. "Limitation of size" is
- another such tactic. Predicates can _always_ be "reified" in the
- sense of being quoted; paradoxes along this line have different sorts
- of solutions.

-
- It depends on what you mean by "meaningful". "is an element of
- itself" is a meaningful predicate in the sense that ascribing it to
- any object (construe this as a syntactical operation!) yields a
- meaningful sentence. I don't think that any predicate is "meaningful"
- in the sense of referring to something _qua_ predicate; verbs are not
- nouns. Some predicates have extensions which can have meaningful
- names.
