Dialogue and Dialectical Logic

An utterance requests a response from an addressee.  So, even a refusal to execute what is proposed in the utterance constitutes a consent to respond, in contrast with the refusal expressed in ignoring the utterance.  Likewise, in more refined contexts, a contradiction of an assertion is a negation of it that is distinct from the negation expressed by silence.  Hence, 'Dialectical Logic', with its Thesis-Antithesis-Synthesis structure, does not adequately represent the pattern of ordinary dialogical communication.
