Our  second  example  comes from  the  work  of Carl
Jung  and  his  Psychological  Types.   Jung  proposed  a
psychological    analogy    to    the   fourfold   aspect   of
wholeness  in  his  description  of  the  four  "functions."
These  four   are   thinking   and   feeling,   intuition   and
sensation.
     In     this     system,      thinking     and     feeling    are
complementary,       mutually        exclusivemodes      of
evaluation.  When we evaluate by means of the thinking
function,  we  use  external,  objective  criteria,  such  as
logic. But when  we  evaluate  by  means  of  the  feeling
function, we  use  internal,  subjective  criteria,  such  as
personal    values    and     preferences.   Often    we   are
confronted with something  that "makes  sense"  but  that
doesn't   "feel    right,"   or   vice   versa.   Such   apparent
contradictions arise  because  thinking and  feeling  base
their  judgments  on   different  sources  of  information,
sources   that  are  appropriate   only   to   the   particular
function.
     Intuition    and   sensation    are   the   complementary,
mutually  exclusive   modes of   obtaining  information.
Their  purpose  is  to  discover what is, not to evaluate  it.
The    intuitive   function   gathers   information   through
subjective  means  of   perception,  such  as  hunches—it
sniffs out  the possible. The  sensation  function  gathers
information   through   objectively   oriented   modes  of
perception, such as the eyes and hands. For the sensation
function,  "beholding   is  believing,"  while   the  intuitive
function believes in its dreams. A stone, to the sensation
function, is  a  stone; while  for  the intuitive function,  it
might also be a paperweight, or even a companion.
     Jung   noted   that   everyone   has   all  four  functions
operative in their lives. One function, however, is usually
dominant  from   birth.  Part  of  the  life  task  is then  to
develop the  abilities of  the other three functions so that
the four can operate as a harmonious whole. The function
that  is  the  most  difficult  to  develop  is  the one that is
complementary   to   the  dominant   function,  for   it   is
experienced as being opposed to that  dominant  function.
For   the  person  who  approaches   the  world   primarily
through  the  feeling   function,  the  thinking  function  is
experienced  as a cold  and lifeless tyrant whose constant
