Second-order logic has a subtle role in the philosophy of mathematics. It is stronger than first order logic in that it incorporates “for all properties” ...

Classical sources for second-order logic are Hilbert & Ackermann (1938) and Church (1956). 2. Suppose a formula \(\phi\) is logically equivalent to both \(\ exists ...
We will proceed by giving a theory of truth, and of logical consequence, based on a formal language called FOL (the language of First-Order Logic). We adopt a ...
For anybody schooled in modern logic, first-order logic can seem an
philosophical nature concerning its underlying semantics. 2.
The set of formulas of existential second-order logic of vocabulary \(\tau\) ( formulas of \(\mathbf{ESO}[\tau]\)) is the smallest set containing all formulas of ...
