Natural deduction for intuitionistic least and greatest fixedpoint logics : with an  Offers a presentation of classical first-order logic. This book presents a truth tree system based on the work of Jeffrey, as well as a natural deduction system  This restriction is entirely analogous to the restriction of the rule of universal generalization of first-order logic.

▫. Predicate (1st order) Logic. It is relatively easy to check for logical consequence in proposition logic because propositional logic is not very expressive.

But if you care about natural deduction representations of first-order logic, Jape is probably the best fit. $\endgroup$ – Charles Stewart Feb 18 '10 at 13:58 Teaching First-Order Logic with the Natural Deduction Assistant (NaDeA) From, Asta Halkjær; Hatteland, Helge; Villadsen, Jørgen Publication date: 2018 Document Version Publisher's PDF, also known as Version of record Link back to DTU Orbit Citation (APA): From, A.

Most notably, the deduction theorem fails to hold in Birkhoff–von Neumann quantum logic, because the linear subspaces of a Hilbert space form a non-distributive lattice Definition: Sentence - a first order logic formula with no free variables. Semantic deduction theorem claims that in case $\alpha$ is a sentence, and $\Sigma$ is a formula's set.
