﻿THE 
  UNFATHOMED 
  UNIVERSE 
  

  

  amount 
  of 
  common 
  ground 
  between 
  man 
  and 
  IH-JM, 
  by 
  an 
  

   analysis 
  of 
  obligatory 
  modes 
  of 
  activity 
  which 
  \\v 
  call 
  n- 
  

   flexes 
  and 
  tropisms, 
  and 
  so 
  on. 
  Thus 
  science 
  has 
  extended 
  

   its 
  claims. 
  

  

  With 
  the 
  advance 
  of 
  natural 
  knowledge 
  at 
  times 
  very 
  

   slowly, 
  and 
  again 
  by 
  leaps 
  and 
  bounds 
  has 
  come 
  an 
  in- 
  

   creased 
  control 
  of 
  Nature 
  which 
  is 
  as 
  rich 
  in 
  promise 
  as 
  in 
  

   achievement. 
  We 
  have 
  recalled 
  the 
  picture 
  ^Eschylus 
  gav<- 
  

   of 
  our 
  ancestors 
  living 
  in 
  caves, 
  fearful 
  of 
  wild 
  beasts, 
  

   often 
  dying 
  of 
  hunger 
  or 
  of 
  poison, 
  without 
  wood-work 
  <>r 
  

   metals, 
  without 
  fire, 
  without 
  foresight, 
  and 
  unable 
  to 
  think 
  

   of 
  the 
  general 
  well-being. 
  What 
  a 
  contrast 
  between 
  that 
  

   picture 
  and 
  our 
  life 
  to-day. 
  For 
  nowadays 
  the 
  serpent 
  that 
  

   bites 
  Man's 
  heel 
  is 
  in 
  nine 
  cases 
  out 
  of 
  ten 
  microscopic; 
  

   year 
  by 
  year 
  Man 
  increases 
  his 
  mastery 
  over 
  the 
  physical 
  

   forces; 
  he 
  coins 
  wealth 
  out 
  of 
  the 
  thin 
  air; 
  he 
  annihilates 
  

   distance 
  with 
  his 
  shrewd 
  devices; 
  he 
  makes 
  the 
  ether 
  carry 
  

   his 
  messages; 
  he 
  is 
  extending 
  his 
  rule 
  to 
  the 
  heavens; 
  and 
  

   he 
  is 
  making 
  experiments 
  on 
  the 
  control 
  of 
  life 
  itself. 
  In 
  

   the 
  so-called 
  purely 
  physical 
  domain, 
  at 
  least, 
  his 
  dreams 
  

   have 
  more 
  than 
  come 
  true. 
  

  

  After 
  a 
  long 
  period 
  during 
  which 
  science 
  consisted 
  of 
  

   numerous 
  discrete 
  bodies 
  of 
  knowledge, 
  largely 
  related 
  to 
  

   the 
  practical 
  control 
  .of 
  Nature, 
  there 
  began 
  to 
  be 
  concentra- 
  

   tion 
  into 
  a 
  system, 
  a 
  sort 
  of 
  cosmology. 
  Science 
  entered 
  

   upon 
  a 
  new 
  and 
  purely 
  theoretical 
  role 
  of 
  giving 
  man 
  a 
  com- 
  

   posite 
  picture 
  of 
  the 
  world 
  and 
  its 
  processes. 
  This 
  is 
  in- 
  

   creasingly 
  impressive, 
  the 
  more 
  we 
  realise 
  it- 
  -which 
  means 
  

   hard 
  work. 
  After 
  a 
  long 
  ascent 
  we 
  get 
  a 
  new 
  view, 
  rcstheti- 
  

   cally 
  magnificent, 
  intellectually 
  a 
  revelation 
  of 
  connected- 
  

   ness. 
  But, 
  fine 
  as 
  it 
  is, 
  the 
  scientific 
  picture 
  has 
  satis- 
  

   fied 
  very 
  few 
  thinkers 
  of 
  distinction, 
  the 
  chief 
  reason 
  being
