﻿THE 
  PROBLEM 
  OF 
  BODY 
  AND 
  MIND

  the 
  day. 
  The 
  question 
  is 
  whether, 
  with 
  this 
  regulative 
  

   principle 
  in 
  view, 
  we 
  can 
  think 
  of 
  mind 
  acting 
  on 
  body 
  or 
  

   of 
  body 
  acting 
  on 
  rnind 
  ? 
  

  

  Various 
  answers 
  have 
  been 
  given, 
  and 
  we 
  shall 
  take 
  the 
  

   worst 
  first. 
  (1) 
  It 
  has 
  been 
  suggested 
  that 
  some 
  physical 
  

   energy 
  may 
  rise 
  into 
  mental 
  energy 
  and 
  some 
  mental 
  energy 
  

   may 
  sink 
  into 
  physical 
  energy. 
  But 
  mental 
  energy 
  is 
  a 
  

   mere 
  metaphor. 
  On 
  this 
  theory 
  it 
  is 
  supposed 
  that, 
  if 
  the 
  

   physical 
  energy 
  is 
  locally 
  augmented 
  by 
  the 
  influence 
  of 
  

   mind, 
  e.g., 
  of 
  a 
  strong 
  will, 
  a 
  corresponding 
  amount 
  of 
  phys- 
  

   ical 
  energy 
  in 
  another 
  part 
  of 
  the 
  system 
  disappears, 
  say 
  

   in 
  engendering 
  a 
  feeling 
  of 
  self-approbation. 
  When 
  the 
  

   resources 
  of 
  the 
  change-office 
  till 
  are 
  augmented 
  by 
  a 
  remark- 
  

   able 
  operation 
  in 
  receiving 
  cash 
  they 
  are 
  automatically 
  re- 
  

   duced 
  to 
  a 
  corresponding 
  amount 
  by 
  a 
  remarkable 
  operation 
  

   in 
  disbursing 
  the 
  same. 
  This 
  seems 
  more 
  like 
  art 
  than 
  

   science 
  and 
  the 
  preservation 
  of 
  the 
  balance 
  savours 
  of 
  the 
  

   miraculous. 
  

  

  (2) 
  We 
  have 
  already 
  referred 
  to 
  Professor 
  Poynting's 
  sug- 
  

   gestion 
  that 
  the 
  will 
  may 
  act 
  as 
  a 
  guiding 
  power 
  changing 
  

   the 
  direction 
  of 
  motion 
  of 
  the 
  atoms 
  and 
  molecules 
  of 
  tho 
  

   brain, 
  and 
  that 
  the 
  amount 
  of 
  energy 
  will 
  not 
  be 
  changed, 
  

   since 
  a 
  deflecting 
  force 
  does 
  no 
  work. 
  " 
  But 
  the 
  interposi- 
  

   tion 
  of 
  the 
  guiding 
  power 
  does 
  affect 
  the 
  transformation 
  of 
  

   energy; 
  instead 
  of 
  the 
  clash 
  which 
  the 
  physicist 
  would 
  fore- 
  

   tell 
  there 
  would 
  be 
  a 
  new 
  configuration 
  as 
  the 
  molecules 
  

   glided 
  past 
  each 
  other 
  in 
  their 
  new 
  directions." 
  This 
  is 
  an 
  

   interesting 
  position, 
  but 
  the 
  difficulty 
  of 
  thinking 
  of 
  mind 
  

   shunting 
  material 
  particles 
  is 
  surely 
  hardly 
  less 
  than 
  the 
  dif- 
  

   ficulty 
  of 
  materialism 
  that 
  brain-motion 
  causes 
  consciousness. 
  

   It 
  is 
  almost 
  certain 
  that 
  this 
  attempt 
  to 
  square 
  animism 
  

   and 
  the 
  doctrine 
  of 
  the 
  conservation 
  of 
  energy 
  is 
  on 
  quite
