Dialectic, which is the parent of logic, came itself from rhetoric. Rhetoric is in turn the child of the myths and poetry of ancient Greece. That is so historically, and that is so by any application of common sense. The poetry and the myths are the response of a prehistoric people to the universe around them made on the basis of Quality. It is Quality, not dialectic, which is the generator of everything we know.
