... NB. One should be careful to distinguish completeness of a system of axioms in the usual sense from completeness of a sentence A(Q) expressing formal axioms and rules of a quantifier Q in the sense that it meets this criterion. For example, let Qα be the type ⟨ 1⟩ quantifier which holds of a subset ...

... Proof. We will show by induction on the degree of a proposition that an interpretation v0 : S → B has an extension to a valuation v : Prop → B. The uniqueness of this extension is obvious from Theorem 1. We set v(a) = v0 (a) for all a of degree 0. Then v is certainly a valuation on the set of degree ...
