Now that we have a logic framework for propositional
logics, we use it to explore genuine negation in
cartesian logic. So far we use ~A = A -> f as an
abbrevation, so ~A was replaced before starting
the proof search. Now we present a cartesian logic
that has genuinly formulas of the form ~A.
We use a notation change idea burried in Johansson
Ingebrigts Minimal Logic Paper from 1937. Further
the logic framework was extended by a generic
usage analysis. Our ~(A=>B) = A/\\~B duality
investigation could be replicated with the
new genuine negation.
