\Di`a*lec"tics\, n. [L. dialectica (sc. ars), Gr. ?
(sc. ?): cf. F. dialectique.]
That branch of logic which teaches the rules and modes of
reasoning; the application of logical principles to
discursive reasoning; the science or art of discriminating
truth from error; logical discussion.
Note: Dialectics was defined by Aristotle to be the method of
      arguing with probability on any given problem, and of
      defending a tenet without inconsistency. By Plato, it
      was used in the following senses:
1. Discussion by dialogue as a method of scientific
   investigation.
2. The method of investigating the truth by analysis.
3. The science of ideas or of the nature and laws of being --
   higher metaphysics. By Kant, it was employed to signify
   the logic of appearances or illusions, whether these arise
   from accident or error, or from those necessary
   limitations which, according to this philosopher,
   originate in the constitution of the human intellect.
