In predicate logic, generalization (also universal generalization or universal introduction, GEN) is a valid inference rule. It states that if $${\displaystyle \vdash \!P(x)}$$ has been derived, then $${\displaystyle \vdash \!\forall x\,P(x)}$$ can be derived. See more Prove: $${\displaystyle \forall x\,(P(x)\rightarrow Q(x))\rightarrow (\forall x\,P(x)\rightarrow \forall x\,Q(x))}$$ is derivable from $${\displaystyle \forall x\,(P(x)\rightarrow Q(x))}$$ and Proof: See more • First-order logic • Hasty generalization • Universal instantiation See more Web9.
