Full Idea
Boolos proposes that second-order quantifiers be regarded as 'plural quantifiers' are in ordinary language, and has developed a semantics along those lines. In this way they introduce no new ontology.
Gist of Idea
Second-order quantifiers are just like plural quantifiers in ordinary language, with no extra ontology
