Etymologically, Cosmotheism differs from 'Pan-theism' in that "pan" is Classical Greek for all, while the Greek word cosmos means an orderly and harmonious universe. Cosmotheists take this as meaning the divine is tantamount to reality and consciousness, an inseparable part of an orderly, harmonious, and whole universal system.
In its broadest sense, the word Cosmotheism may be considered simply as being synonymous with pantheism, although not all modern pantheists would accept Cosmotheism as a synonym for their own worldview due to the historical association of Cosmotheism with a political movement, white separatism, which some within the pantheist community may find objectionable.
According to a Cosmotheist Web site dedicated to the late Dr.William L. Pierce:
"Cosmotheism is a religion which positively asserts that there is an internal purpose in life and in cosmos, and there is an essential unity, or consciousness that binds all living beings and all of the inorganic cosmos, as one."
"What is our true human identity is we are the cosmos made self-aware and self-conscious by evolution. "
"Our true human purpose is to know and to complete ourselves as conscious individuals and also as a self-aware species and thereby to co-evolve with the cosmos towards total and universal awareness, and towards the ever higher perfection of consciousness and being."[1]
Some claim Albert Einstein was a Cosmotheist, [1], along with Carl Sagan, Benedict Spinoza and other historical figures—although there is no quoted evidence of any of these three claiming to be "cosmotheist" as such, and all could also be said to be Pantheist.
In Israel, Cosmotheism was described by Mordekhay Nesiyahu, one of the foremost ideologists of the Israeli Labor Movement and a lecturer in its college Beit Berl in Israel.
In Cosmotheism — Israel, Zionism, Judaism and Humanity towards the 21st Century, Nesiyahu proposed not to just assume the existence of God, being "prior to all that was created," but to consider God as only being a result of the development of the universe and the consciousness of all of humankind.
Divinity in this particular view is inherently a human invention.
The development of the divine (or what the believer would qualify as being "the revelation of the Divine") was, in Nesiyahu's opinion, both the condition for a more exalted human functioning and all that bears the fruit that comes out of it.
In Nesiyahu's universalist re-imagining of a secular divinity, the universal celebration of Cosmotheism is the basis for rebuilding the Jewish Temple in Jerusalem, and is also a secular ethnically Jewish and a Zionist contribution to all of humankind.
"All we require is that you share with us a commitment to the simple, but great, truth which I have explained to you here, that you understand that you are a part of the whole, which is the creator, that you understand that your purpose, the purpose of mankind and the purpose of every other part of creation, is the creator's purpose, that this purpose is the never-ending ascent of the path of creation, the path of life symbolized by our life rune, that you understand that this path leads ever upward toward the creator's self-realization, and that the destiny of those who follow this path is godhood."
Pierce believed in a hierarchical society governed by what he saw as the essential principles of nature, including the survival of the fittest. In his social schema, the best-adapted genetic stock, which he believed to be the white race, should remain separated from other races; and within an all-white society, the most fit individuals should lead the rest. He thought that extensive programs of "racial cleansing" and of eugenics, both in Europe and in the U.S., would be necessary to achieve this socio-political program.
His National Alliance was to be the political vanguard and the spiritual priesthood of this program, which was designed ultimately to bring about a "White racial redemption". His Cosmotheist Community Church, which was to be the next step of this plan, was set up in the mid-1970s, alongside Pierce's other political projects — the National Alliance, National Vanguard Books, and the weekly broadcast American Dissident Voices — all from his mountain retreat headquarters in West Virginia.
Other criticisms have been harsher; for example, the Southern Poverty Law Center has characterized Pierce's Cosmotheism as "an unsuccessful tax dodge". (Followers of Pierce's cosmotheism call many of these characterizations erroneous, some National Alliance members attributing them to "Marxist politically-correct slander and dogmatism.")
