  THE 
  PROBLEM 
  OF 
  BODY 
  AND 
  MIND 
  

  

  " 
  The 
  mind 
  is 
  somehow 
  a 
  mid-term 
  receiving 
  messages 
  from 
  

   the 
  object 
  in 
  the 
  external 
  world 
  and 
  issuing 
  messages 
  to 
  the 
  

   organs 
  concerned 
  in 
  behaving 
  appropriately 
  to 
  that 
  object. 
  

   Whenever 
  the 
  mind 
  is 
  thus 
  effective 
  in 
  guidance 
  we 
  have 
  

   what 
  we 
  called 
  a&c-process. 
  The 
  distinguishing 
  feature 
  in 
  

   such 
  guidance 
  is 
  a 
  context 
  of 
  meaning 
  within 
  a 
  sphere 
  of 
  

   interest." 
  Using 
  the 
  term 
  mind 
  in 
  this 
  sense, 
  we 
  have 
  to 
  

   consider 
  its 
  relation 
  to 
  the 
  processes 
  that 
  go 
  on 
  in 
  the 
  cortex 
  

   of 
  the 
  brain, 
  and, 
  anticipating 
  our 
  subsequent 
  discussion, 
  

   we 
  may 
  say 
  that 
  there 
  are 
  two 
  main 
  views. 
  " 
  According 
  

   to 
  the 
  first 
  there 
  are 
  two 
  radically 
  distinct 
  and 
  wholly 
  dis- 
  

   parate 
  orders 
  of 
  being 
  the 
  mental 
  order 
  and 
  the 
  physical 
  

   order," 
  which 
  interact. 
  " 
  According 
  to 
  the 
  second 
  there 
  

   is 
  only 
  one 
  order 
  within 
  which 
  there 
  are 
  distinguishable 
  

   types 
  of 
  relatedness 
  and 
  of 
  process, 
  e.g., 
  physical, 
  physio- 
  

   logical, 
  and 
  psychical. 
  Any 
  given 
  term 
  may 
  be 
  coincidentally 
  

   related 
  to 
  other 
  terms 
  in 
  these 
  severally 
  distinguishable 
  ways. 
  

   This 
  is 
  the 
  a&c-mterpretation 
  already 
  suggested." 
  On 
  the 
  

   second 
  view 
  the 
  c 
  process 
  is 
  always 
  correlated 
  with 
  ab 
  

   processes 
  ; 
  on 
  the 
  first 
  view 
  the 
  c 
  process 
  is 
  independent 
  of 
  

   any 
  physiological 
  correlate. 
  

  

  2. 
  What 
  Must 
  Be 
  Recognised 
  from 
  the 
  Biological 
  Side. 
  

  

  It 
  is 
  possible, 
  as 
  we 
  have 
  seen, 
  to 
  apply 
  to 
  a 
  living 
  body 
  

   many 
  of 
  the 
  methods 
  of 
  chemistry 
  and 
  physics, 
  and 
  to 
  give 
  

   chemical 
  and 
  physical 
  descriptions 
  of 
  isolated 
  observed 
  

   processes. 
  The 
  more 
  that 
  is 
  done, 
  the 
  more 
  will 
  the 
  distinc- 
  

   tively 
  vital 
  stand 
  out 
  in 
  relief. 
  If 
  it 
  can 
  be 
  shown 
  that 
  the 
  

   balsam's 
  jerking 
  out 
  of 
  its 
  seeds 
  admits 
  of 
  complete 
  mechani- 
  

   cal 
  description 
  in 
  terms 
  of 
  tensions, 
  elasticity, 
  and 
  the 
  like 
  

   the 
  more 
  obvious 
  will 
  be 
  the 
  distinctively 
  vital 
  factor 
  in 
  

   the 
  sundew's 
  fly-catching 
  successes. 
  But 
  no 
  adequate 
  chem-
