logique des predicats du premier ordre to the rescue ?
- author:: Richard Montague
- translation into logic :
\text{An } N \mapsto \exists x (N'(x) \wedge \dots)\exists x P(x)iff there exists a witnessbsuch thatP(b)is true- Every / each
\mapsto\forall x \vdots
- = A famous supervisor directs every student here.
- there are two interpretations :
\exists x (\operatorname{fam-sup}'(x) \wedge \forall y (\operatorname{student}(y) \to \operatorname{Direct}(x, y)))\forall y (\operatorname{student}(y) \to \exists x(\operatorname{fam-sup}'(x) \wedge \operatorname{Direct}(x, y))
- = no player injured herself
\forall x (\operatorname{player}(x) \to \neg \operatorname{Injure}(x, x)\neg \exists x (\operatorname{player}(x) \wedge \operatorname{Injure}(x, x))
