Definition wConsistent (T : System) :=
forall (f : Formula) (v : nat),
(forall x : nat, In x (freeVarFormula LNN f) -> v = x) ->
SysPrf T (existH v (notH f)) ->
exists n : nat, ~ SysPrf T (substituteFormula LNN f v (natToTerm n)).

Lemma notCon2wNotCon :
forall T : System, Inconsistent LNN T -> wInconsistent T.
