With  the  introduction  of  money  even  the  form  of
force  disappears :  the  labourer  pays  rent,  and  the
lord  pays  his  soldiers.  It  is  free  exchange  on  both
sides,  and  economic  force  has  replaced  physical
force.     The   further  the   drift   from    force   towards

simple  economic  interest,  the  better  the  result  for
the  effort  expended.  The  Tartar  khan,  who  seizes
by  force  the  wealth  in  his  State,  giving  no  adequate
return,  soon  has  none  to  seize.  Men  will  not  work
to  create  what  they  cannot  enjoy,  so  that  finally
the  khan  has  to  kill  a  man  by  torture  in  order  to
obtain  a  sum  which  is  the  thousandth  part  of  what
a  London  tradesman  will  spend  to  secure  a  title
carrying  no  right  to  the  exercise  of  force,  from  a
Sovereign  who  has  lost  all  right  to  the  use  or  exer-
cise of  physical  force,  the  head  of  the  wealthiest
country  in  the  world,  the  sources  of  whose  wealth
are  the  most  removed  from  any  process  involving
the  exercise  of  physical  force.
