During the last thirty years philosophers in the West have critiqued the underlying assumptions of Modern philosophy in relation to the natural world. This development has been part of an ongoing expansion of philosophical work involving cross cultural studies of world views or ultimate philosophies. Since philosophical studies in the West have often ignored the natural world, and since most studies in ethics have focused on human values, those approaches which emphasize ecocentric values have been referred to as ecophilosophy. Just as the aim of traditional philosophy is sophia or wisdom, so the aim of ecophilosophy is ecosophy or ecological wisdom. The Practice of ecophilosophy is an ongoing, comprehensive, deep inquiry into values, the nature of the world and the self. The mission of ecophilosophy is to explore a diversity of perspectives on human-Nature contexts and interrelationships. It fosters deeper and more harmonious relationships between place, self, community and the natural world. This aim is furthered by comparing the diversity of ecosophies from which people support the platform principles of the global, long range, deep ecology movement.
