Theoretics \The`o*ret"ics\, n.
   The speculative part of a science; speculation.

         At the very first, with our Lord himself, and his
         apostles, as represented to us in the New Testament,
         morals come before contemplation, ethics before
         theoretics.                              --H. B.
