MY PURPOSE IS SIMPLY TO SHOW THAT A RATIONAL POLICY MUST 

 RECOGNIZE CERTAIN GENERAL TRUTHS OF BIOLOGY; AND TO INSIST THAT 

 ONLY WHEN STUDY OF THESE GENERAL TRUTHS, AS ILLUSTRATED THROUGH- 

 OUT THE LIVING WORLD, HAS WOVEN THEM INTO THE CONCEPTIONS OF 

 THINGS, IS THERE GAINED A STRONG CONVICTION THAT DISREGARD OF 

 THEM MUST CAUSE ENORMOUS MISCHIEFS. 



HERBERT SPENCER in The Study of Sociology (p. 346).

[REASON (IF SUCH AN ONE AS I MAY PRONOUNCE ANY JUDGMENT) 

 REQUIRES US TO BELIEVE, THAT, BE THE SYMPTOMS OF IT, WHICH AFFLICT 

 THE HUMAN BODY, NEVER SO SEVERE, DISEASE IS NOTHING ELSE BUT THE 

 EFFORT OF NATURE, ATTEMPTING BY EVERY MEANS THE EXTERMINATION OF 

 THE DISEASE-PRODUCING MATTER, FOR THE HEALTH OF THE PATIENT.]
