VALUES AND BELIEFS determine the way we perceive the world and suggest the ways we prioritize the responses to our perceptions. They affect almost all areas of our judgment and behavior. However, in the wider context of society individual values and beliefs are unlikely to conform to a common standard. If mutually consistent values and beliefs are not to be imposed “from above,” a further factor needs to be present. This is a shared ethic: the acceptance of a common morality. In an interdependent world, this ethic must be shared by the entire human family; it must be a planetary ethic.
