Work in Progress
Book
- Logical Foundations (with Zachary Goodsell). This book introduces and motivates LF, a new system of logic, through its applications in mathematics, syntax (including the theory of computability and metatheory), and semantics.
Advance praise for Logical Foundations
"Recent work by Goodsell and Yli-Vakkuri [in Logical Foundations] [...] indicates that systems like [The Bounds of Possibility]’s are too weak for mathematical purposes, because they lack an adequate comprehension principle for functions. Goodsell and Yli-Vakkuri’s own system LF of higher-order logic has such a principle, as a corollary of an axiom of choice. Although LF individuates functions extensionally, it is not extensional, for it implies that some materially equivalent propositions are distinct. LF is intensional; whenever a biconditional is provable, so is the corresponding propositional identity. They show LF to suffice for most of contemporary mathematics: a new version of logicism. My money has always been on mathematical power to beat metaphysical qualms, not least in higher-order modal logic [...]. LF incorporates modality by identifying necessity with being identical to the weakest truth. They derive the strong modal logic S5, the necessity of identity and distinctness, and the Barcan formula and its converse. Mathematical strength and modal strength go naturally together.”
