"…The civilization now in jeopardy is all humanity. As the ancient myth makers knew, we are children equally of the earth and sky. In our tenure of this planet, we have accumulated dangerous, evolutionary baggage -- propensities for aggression and ritual, submission to leaders, hostility to outsiders, all of which puts our survival in some doubt. We have also acquired compassion for others, love for our children, a desire to learn from history and experience, and a great, soaring passionate intelligence -- the clear tools for our continued survival and prosperity."
