  although 
  it 
  should 
  be 
  said 
  that 
  Darwinism 
  in 
  the 
  narrow 
  sense 
  

   never 
  seemed 
  to 
  him 
  a 
  sufficient 
  explanation 
  of 
  the 
  origin 
  of 
  

   species. 
  To 
  attempt 
  to 
  explain 
  his 
  views 
  in 
  full 
  would 
  be 
  

   inappropriate 
  in 
  this 
  place, 
  but 
  by 
  quoting 
  a 
  few 
  sentences 
  

   from 
  the 
  closing 
  chapter 
  of 
  the 
  last 
  edition 
  of 
  his 
  Manual 
  

   (1895), 
  the 
  main 
  points 
  in 
  the 
  position 
  finally 
  reached 
  may 
  be 
  

   shown. 
  

  

  .... 
  The 
  principles 
  above 
  stated 
  are 
  all 
  in 
  accord 
  with 
  a 
  

   theory 
  of 
  evolution 
  and 
  through 
  the 
  added 
  facts 
  of 
  later 
  years, 
  

   they 
  favor 
  the 
  view 
  of 
  evolution 
  by 
  natural 
  variation. 
  

  

  .... 
  It 
  is 
  perceived 
  that 
  the 
  law 
  of 
  nature 
  here 
  exempli- 
  

   fied 
  is 
  not 
  " 
  like 
  produces 
  like," 
  but 
  like 
  with 
  an 
  increment 
  or 
  

   some 
  addition 
  to 
  the 
  variation. 
  Consequently, 
  the 
  law 
  of 
  

   nature, 
  as 
  regards 
  kingdoms 
  of 
  life, 
  is 
  not 
  permanence 
  but 
  

  

  change, 
  evolution 
  The 
  survival 
  of 
  the 
  fittest 
  is 
  a 
  

  

  fact 
  ; 
  and 
  the 
  fact 
  accounts 
  in 
  part 
  for 
  the 
  geographical 
  dis- 
  

   tribution 
  of 
  the 
  races 
  of 
  men 
  now 
  existing 
  and 
  still 
  in 
  pro- 
  

   gress 
  ; 
  but 
  not 
  for 
  the 
  existence 
  of 
  the 
  fittest, 
  or 
  for 
  the 
  power 
  

  

  that 
  has 
  determined 
  survival 
  But 
  the 
  origin 
  of 
  the 
  

  

  variation 
  is 
  without 
  explanation. 
  And 
  so 
  it 
  is 
  for 
  the 
  most 
  

   part 
  throughout 
  the 
  kingdoms 
  of 
  life. 
  Enough 
  is 
  known 
  to 
  

   encourage 
  study. 
  

  

  And 
  finally, 
  the 
  closing 
  paragraph 
  of 
  the 
  work 
  is 
  as 
  follows 
  : 
  

  

  Whatever 
  the 
  results 
  of 
  further 
  search, 
  we 
  may 
  feel 
  assured, 
  

   in 
  accord 
  with 
  Wallace, 
  who 
  shares 
  with 
  Darwin 
  in 
  the 
  author- 
  

   ship 
  of 
  the 
  theory 
  of 
  Natural 
  Selection, 
  that, 
  the 
  intervention 
  

   of 
  a 
  Power 
  above 
  Nature 
  was 
  at 
  the 
  basis 
  of 
  man's 
  develop- 
  

   ment. 
  Believing 
  that 
  nature 
  exists 
  through 
  the 
  will 
  and 
  ever- 
  

   acting 
  power 
  of 
  the 
  Divine 
  Being, 
  and 
  that 
  all 
  its 
  great 
  truths, 
  

   its 
  beauties, 
  its 
  harmonies, 
  are 
  manifestations 
  of 
  His 
  wisdom 
  

   and 
  power, 
  or, 
  in 
  the 
  words 
  nearly 
  of 
  Wallace, 
  that 
  the 
  whole 
  

   Universe 
  is 
  not 
  merely 
  dependent 
  on, 
  but 
  actually 
  is, 
  the 
  Will 
  

   of 
  one 
  Supreme 
  Intelligence, 
  Nature, 
  with 
  man 
  as 
  its 
  culmi- 
  

   nant 
  species, 
  is 
  no 
  longer 
  a 
  mystery. 
  

  

  These 
  are 
  the 
  words 
  of 
  the 
  Christian 
  Philosopher, 
  with 
  a 
  

   rarely 
  comprehensive 
  grasp, 
  and 
  with 
  whom 
  the 
  faith 
  of 
  his 
  

   youth 
  only 
  grew 
  stronger 
  as 
  his 
  insight 
  became 
  deeper 
  into 
  

   Nature's 
  laws.
