Secondly, since DS is a valid classical inference, we can see clearly that a paraconsistent logic will validate fewer inferences than classical logic.
(No classically invalid inferences are going to become valid by dint of inconsistent information.)
That is the whole idea―that classical logic allows too much, and especially given the possibility of inconsistency, we must be more discriminating.
This is sometimes expressed by saying that paraconsistent logics are ‘weaker’ than classical logic; but since paraconsistent logics are more flexible and apply to more situations, we needn’t focus too much on the slang.
Classical logic is in many ways more limited than paraconsistent logic (see §4c.).
