A Note on Naive Set Theory in LP
... a naive set theory is not without justification. As we have noticed, it is easy to work in since models are quite easy to construct. Secondly, it is perhaps the most natural paraconsistent expansion of classical predicate logic. It leaves all things in predicate logic as they are, except to allow th ...

A collection S of subsets of a set A is called pairwise disjoint if every two distinct subsets that belong to S are disjoint. A partition of A can be defined as a collection S of nonempty subsets of A such that every element o ...
