Take the story of Cain and Abel. Why were we given that story? Scientifically, you may have an explanation for it, but I'm not approaching it from the scientific point of view. I'm saying: Why do we need that? It's a sordid story, a depressing story, a dark story. Why should I believe that I'm a descendant of either Cain or Abel? Thank God there is a third son! [Genesis 4:25]
Elie WieselRemember also that it is not knowledge but the yearning for knowledge that makes for a complete, accomplished man. Such a man does not stand still but perseveres in the face of adversity, nor does he remain untouched by the pain cause by absence. On the contrary, he recognizes himself in each cry, uttered or repressed, in the smallest rift, in the most pressing need.
