Immanentism is a belief system which views "God" as being inseparable from Nature, as opposed to a being outside of it. More to the point, Immanentism says that one might find "God" wherever s/he seeks her/him; or, more broadly, that "God" pervades our world. A prominent proponent of Immanentism was Henry David Thoreau.
Immanentdualism is a processual and multidimensional world view (i.e., pluralistic, historical, narrative and evolving) rather than mechanistic, linear and unidimensional.
Immanentdualism relates the similarities and differences in one world view in a manner that produces unique distinctions that cannot be singularly made by either monism or dualism.
Immanentdualism, as an alternative world view to dualism and monism, suggests that the optimum path for avoiding collapse is a process of social change which combines scientific-technological rationality and "the seamless web." With such a world view, ideas might once again influence the unfolding of history.
