   Gr. ?; ? against + ? to suffer. Cf. F. antipathie. See
   {Pathos}.]
   1. Contrariety or opposition in feeling; settled aversion or
      dislike; repugnance; distaste.

            Inveterate antipathies against particular nations,
            and passionate attachments to others, are to be
            avoided.                              --Washington.

   2. Natural contrariety; incompatibility; repugnancy of
      qualities; as, oil and water have antipathy.
