Although  we  may  not  be  able  clearly  to  trace  the  line
of  distinction  between  man  and  other  animals,  the  dis-
tinction is  unquestionable,  and  resides  in  the  qualities  of
the  human  spirit.  Even  between  the  lowest  of  men  and
the  highest  of  lower  animals  there  is  a  vast  interval;  for
man,  even  at  the  lowest,  possesses  powers  that  can  be
developed,  as  experience  shows,  into  the  full  life  of  the
spirit.  We  may  grant  that  like  the  principle  of  life,  the
principle  of  mind,  expressed  in  man,  finds  genuine  though
partial  expression  in  the  animal  world  below  him.  Yet
it  is  true  that  man  is  unique  in  spite  of  his  community
with  the  inferior  world,  and  stands  on  a  plane  of  essential
separateness,  by  virtue  of  qualities  that  are  all  his  own.
In  the  capacities  of  the  human  spirit  is  found  that
image  or  likeness  of  God,  the  biblical  suggestion  of
which  has  been  so  fruitful  in  Christian  thought.  The
constitution  of  man  as  a  spirit  is  like  that  of  God  as  a
spirit.  The  qualities  that  distinguish  man  from  other
beings  on  the  earth  are  in  some  true  sense  qualities  that
he  shares  with  God.  In  his  measure,  he  differs  from  the
creation  below  him  as  God  does.  His  body  is  akin  to
the  material  universe,  and  bears  the  likeness  of  terres-
trial organization,  but  his  spirit  is  akin  to  the  eternal
creative  Spirit,   and  bears  the  likeness  of  God.
