            Thought can not be superadded to matter, so as in

            which should indeed have died With them they think
            on?                                   --Shak.

            Thoughts come crowding in so fast upon me, that my

      longer; a thought better. [Colloq.]

            If the hair were a thought browner.   --Shak.

   Note: Thought, in philosophical usage now somewhat current,
         denotes the capacity for, or the exercise of, the very
         highest intellectual functions, especially those
         usually comprehended under judgment.

               This [faculty], to which I gave the name of the
               ``elaborative faculty,'' -- the faculty of
               relations or comparison, -- constitutes what is
               properly denominated thought.      --Sir W.
                                                  Hamilton.
