  in 
  a 
  preliminary 
  way 
  to 
  see 
  to 
  what 
  specific 
  depictions 
  of 
  the 
  general 
  

   psychical 
  universe 
  it 
  may 
  lead 
  us. 
  However, 
  I 
  can 
  here 
  only 
  express 
  

   my 
  belief 
  — 
  justified 
  by 
  theoretical 
  results 
  already 
  achieved 
  — 
  that 
  

   the 
  doctrine 
  of 
  psychical 
  monism 
  will 
  not 
  only 
  throw 
  light 
  upon 
  the 
  

   mysteries 
  of 
  physics 
  and 
  of 
  metaphysics 
  but 
  also 
  upon 
  those 
  of 
  religion 
  

   and 
  of 
  ethics. 
  When 
  we 
  know 
  exactly 
  what 
  manner 
  of 
  universe 
  we 
  

   live 
  in 
  we 
  shall 
  know 
  whither 
  that 
  universe 
  is 
  going 
  and 
  what 
  our 
  own 
  

   part 
  must 
  be 
  in 
  its 
  evolution.

  the 
  early 
  explorers

  under 
  ground; 
  tomatoes 
  

   and 
  capsicum 
  peppers 
  from 
  solanaceous 
  plants 
  of 
  the 
  hill-sides 
  and 
  plains; 
  

   pineapples

  prickly-leaved 
  plants 
  of 
  certain 
  semi-arid 
  regions 
  of 
  

   Central 
  America; 
  chocolate 
  from 
  the 
  seeds

  the 
  

   narcotic 
  henbane 
  of 
  the 
  Old 
  World.
