The foundationalist view of nature like Deep Ecology is rooted in Plato''s Ideology, per se. In other words, a priori reasoning has justified the intrinsic value of nature since Deep Ecology launched its ecological agenda in the early 1970s. However, any essentialist view of nature cannot afford its logical justification without reducing to anthropomorphism or discourse for the privileged, just as criticized by the post-modern discourse, social ecology, eco-feminism and the buddhist ecology in common. That is why we need not the philosophy of reduction but one of organic articulation. And Deweyan environmental pragmatism suggests such an organic view of nature. John Dewey does not accept a priori reasoning as his epistemological logic. At most, it works as a part of supernatural experience. The organic concept of experience, which is individual or communal as well as tangible or intangible, helps to find the way to face the problematic situation. Believing in the power of experimental intelligence and plurality, we might say, Dewey attempts to reconstruct a new ecological philosophy on the basis of scientific inquiry. Thus, Deweyan eco-sophy escapes from its logical dilemma on the one hand, it could well-function as an efficient environmental discourse on the other
