Publisher's Note The twentieth century has been the bloodiest, most destructive century in all of human history. The determining challenge of the twenty-first century will be whether or not human beings can learn to live together and cooperate on all levels -- from the nuclear family to the human family.

War and domination, while pervasive in the last few millennia are actually exceptions in human evolution and could become the exception again.
