﻿ANIMAL 
  BEHAVIOUR

  tactics 
  of 
  Animate 
  Nature 
  to 
  economise 
  mental 
  activity 
  for 
  

   higher 
  issues 
  by 
  a 
  structural 
  organisation 
  or 
  registration 
  

   (badly 
  called 
  mechanisation) 
  of 
  capacities 
  for 
  effective 
  

   agency. 
  Thus 
  instinctive 
  capacity 
  being 
  a 
  substitute 
  for 
  

   instruction 
  may 
  make 
  emancipated 
  experiment 
  practicable, 
  

   as 
  birds 
  well 
  illustrate. 
  

  

  12. 
  Rational 
  Conduct. 
  

  

  In 
  the 
  case 
  of 
  man, 
  and 
  probably 
  in 
  his 
  case 
  only, 
  there 
  

   is 
  sometimes 
  evidence 
  of 
  rational 
  conduct 
  as 
  contrasted 
  with 
  

   intelligent 
  behaviour. 
  We 
  cannot 
  describe 
  such 
  conduct 
  with- 
  

   out 
  using 
  general 
  terms; 
  we 
  know 
  personally 
  that, 
  like 
  

   original 
  thinking, 
  it 
  involves 
  experimenting 
  with 
  abstract 
  

   ideas 
  ; 
  it 
  implies 
  conceptual 
  as 
  distinguished 
  from 
  perceptual 
  

   inference 
  ; 
  it 
  is 
  controlled 
  in 
  reference 
  to 
  an 
  ideal 
  or 
  pur- 
  

   pose. 
  We 
  wonder 
  whether 
  even 
  at 
  this 
  level 
  there 
  may 
  not 
  

   be 
  a 
  continuance 
  of 
  the 
  organisation-process, 
  for 
  mathema- 
  

   ticians 
  of 
  distinction 
  and 
  other 
  original 
  thinkers 
  assure 
  us 
  

   of 
  the 
  reality 
  of 
  unconscious 
  cerebration, 
  and 
  the 
  absolute 
  

   trustworthiness 
  of 
  the 
  immediate 
  ethical 
  judgment 
  of 
  fine 
  

   characters 
  may 
  be 
  another 
  illustration 
  in 
  a 
  different 
  field. 
  

   There 
  is 
  an 
  assured 
  immediacy 
  of 
  reaction 
  in 
  many 
  cases 
  

   that 
  makes 
  the 
  ordinary 
  person 
  marvel, 
  and 
  leaves 
  the 
  moral 
  

   genius 
  free 
  to 
  tackle 
  more 
  difficult 
  problems. 
  

  

  13. 
  General 
  Impressions 
  of 
  Animal 
  Behaviour. 
  

  

  What 
  we 
  see 
  is 
  like 
  a 
  great 
  staircase, 
  exhibiting 
  wonderful 
  

   perfection 
  at 
  different 
  levels, 
  such 
  as 
  those 
  of 
  tropisms, 
  in- 
  

   stincts, 
  and 
  intelligence. 
  We 
  may 
  distinguish 
  a 
  main 
  line 
  

   of 
  experimenting, 
  ' 
  trial 
  and 
  error 
  ', 
  and 
  initiative 
  from 
  the 
  

   side 
  lines 
  in 
  which 
  organisation 
  or 
  automatisation 
  of 
  be- 
  

   haviour 
  predominates 
  over 
  immediately 
  controlled 
  direction.
