"The overriding need is "to develop a new Planetary Humanism" that will seek to preserve human rights and enhance human freedom and dignity and will emphasize our commitment "to humanity as a whole." The underlying ethical principle "is the need to respect the dignity and worth of all persons in the world community." Thinkers as diverse as Peter Singer and Hans Küng also emphasize the need for a new global ethic beyond nationalistic, racial, religious, and ethnic chauvinism."
