The Green altitude began roughly 150 years ago, though it came into its fullest expression during the cultural revolution of the 1960s. Green worldviews are marked by pluralism, or the ability to see that there are multiple ways of seeing reality. If orange sees universal truths (“All men are created equal”), green sees multiple universal truths—different universals for different cultures. Green ethics continue, and radically broaden, the movement to embrace all people. A green statement might read, “We hold these truths to be self-evident, that all people are created equal, regardless of race, gender, class….” Green ethics have given birth to the civil rights, feminist, and gay rights movements, as well as environmentalism.

The green worldview’s multiple perspectives give it room for greater compassion, idealism, and involvement, in its healthy form. Such qualities are seen by organizations such as the Sierra Club, Amnesty International, Union of Concerned Scientists, and Doctors Without Borders. In its unhealthy form green worldviews can lead to extreme relativism, where all beliefs are seen as relative and equally true, which can in turn lead to the nihilism, narcissism, irony, and meaninglessness exhibited by many of today’s intellectuals, academics, and trend-setters.
