Civilization develops not from Abel, but from Cain the murderer. The very word "civilization" derives from the Latin word for city. It is the leisure time, community organization and specialization of labor in the first cities that permitted the emergence of the arts and technologies we think of as the hallmarks of civilizations. The first city, according to Genesis, was constructed by Cain, the inventor of agriculture-a technology that requires a fixed abode. And it is his descendants, the sons of Lamech, who invent both "artifices in brass and iron" and musical instruments. Metallurgy and music-technology and art-are in the line from Cain. And the passions that lead to murder do not abate: Lamech says, "For I have slain a man for wounding me, and a young man for bruising me; if Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold." The connection between murder and invention has been with us ever since. Both derive from agriculture and civilization. p.64 Dragons of Eden, Sagan
