The Logic of Relations

  • Nick Earle
Part of the Introductory Monographs in Mathematics book series (INMOMA)


The weakness of a logical system which goes no further into the structure of language than the relation of subject to predicate is that it is unable to deal with quantity. What is characteristic of a quantity is that it can be related in a wide variety of ways to other quantities whereas classes can only be related by inclusion, exclusion (that is, inclusion in the complementary class) or a relation which is neither of these, namely overlapping.
