Instinct

Every doctrine denying to the “single paltry individual” any role in history must finally ascribe changes and improvements to the operation of instincts. As those upholding such doctrines see it, man is an animal that has the instinct to produce poems, cathedrals, and airplanes. Civilization is the result of an unconscious and unpremeditated reaction of man to external stimuli. Each achievement is the automatic creation of an instinct with which man has been endowed especially for this purpose. There are as many instincts as there are human achievements. It is needless to enter into a critical examination of this fable invented by impotent people for slighting the achievements of better men and appealing to the resentment of the dull. Even on the basis of this makeshift doctrine one cannot negate the distinction between the man who had the instinct to write the book On the Origin of Species and those who lacked this instinct.
