 duality. But the exercise of the one has been active 

 from the beginnings of his history indeed we know

 comparatively, has but recently been called into play. 

 So far as its influence on the modern world goes, 

 may we not say that it began at least in the domain 

 of scientific naturalism with the Ionian philosophers? 

 Emotionally, we are hundreds of thousands of years 

 old; rationally, we are embryos. 



In other words, man wondered countless ages 

 before he reasoned; because feeling travels along 

 the line of least resistance, while thought, or the 

 challenge by inquiry therefore the assumption that 

 there may be two sides to a question must pursue 

 a path obstructed by the dominance of custom, the
