Single Idea 10569
[filed under theme 5. Theory of Logic / G. Quantification / 5. Second-Order Quantification
]
Full Idea
We are tempted to ask of second-order quantifiers 'what are you quantifying over?', or 'when you say "for some F" then what is the F?', but these questions already presuppose that the quantifiers are first-order.
Gist of Idea
If you ask what F the second-order quantifier quantifies over, you treat it as first-order
