ABSTRACT

Having established that the memory of multiplicative matrices (classes and relations) develops in full accord with the evolution of the underlying operational schemata, we decided to go on to an examination of the remembrance of simple class intersections. It might, of course, be argued that this complementary analysis can add little to what we already know; after all, an intersection is but a particular case of the multiplicative operations associated with the matrices we discussed in the last chapter. However, we were firmly convinced that intersections pose a special and very real problem: an intersection can (and, from our point of view, must) be considered as an isolated and, hence, incomplete operation, while the matrix multiplication (isomorphous to a Cartesian product) is a complete operation.
