We introduce an new operation called a non-monotonic intersection. This operation has significant applications in default and other commonsense reasoning systems. In addition to being non-monotonic this operator is not a pointwise operator. Futhermore it is neither commutative nor associative but rather supports a concept of priority amongst its arguments.
