By "another paradigm of logic" I meant a more or less dialectical
approach to "logic," like Plato's or Hegel's, which foregrounds
the "opposition" or, more weakly, the contrast, between either
propositions or concepts, e.g. hot vs. cold or near vs. far.  It
has always seemed to me that Aristotle's analytics, which became
"logic" for the modern world, was an attempt to formalize some
relatively minor parts of the dialectical movement of thought. The
logical square does pretty much the same thing for propositions
that Greimas' semiotic square does for unitary concepts.

Some men are not immortal.               All men are immortal.
