Quote - With "our nature" I mean the nature of humanity as a whole rather then individuals. An individual can change the vision of humanity, but it's the vision of humanity as a whole that dictates the road on which we proceed to find new knowledge.

Ah yes, the Borg Syndrome...the collective.  The concept "Humanity as a whole" does not exist, except as a philosophical dead-end, with no rational epistemological foundation.  It is the interaction of individual humans that produces the sense of cultures, not some impossible collective entity.

So what is the nature of "humanity as a whole?" Who determines what that nature shall be? Hitler, Stalin, and Mao claimed to represent large portions of "humanity as a whole,"  and they certainly thought they knew where to dictate the road on which “the whole” would proceed!

One cannot understand the nature of the stars by studying a general observation of the large-scale effects of stars.  The nature of stars is understood by studying the nature of individual stars.

Statistics cannot define the individual, individuals define, and are the basis of statistics.  The same goes for cultures, or humanity for that matter.
