Pantheism (Greek ( 'pan' = all) and ( 'theos' = God) it literally means "God is All" and "All is God") is the view that everything is of an all-encompassing immanent abstract God; or that the Universe, or nature, and God are equivalent. More detailed definitions tend to emphasize the idea that natural law, existence, and the Universe (the sum total of all that is, was, and shall be) is represented in the theological principle of an abstract 'god' rather than a personal, creative deity or deities of any kind. This is the key feature which distinguishes them from panentheists and pandeists. As such, although many religions may claim to hold pantheistic elements, they are more commonly panentheistic or pandeistic in nature.
History of Pantheism
The term "pantheist"—from which the word "pantheism" is derived—was purportedly first used by Irish writer John Toland in his 1705 work, Socinianism Truly Stated, by a pantheist. However, the concept has been discussed as far back as the time of the philosophers of Ancient Greece, by Thales, Parmenides and Heraclitus. The Jewish backgrounds for pantheism may reach as far back as the Torah itself in its account of creation in Genesis and its earlier prophetic material in which clearly "acts of nature" (such as floods, storms, volcanoes, etc.) are all identified as "God's hand" through personification idioms, thus explaining the open references to the concept in both New Testament and Kabbalistic literature.
In 1785 a major controversy began between Friedrich Jacobi and Moses Mendelssohn, which eventually involved many important people of the time. Jacobi claimed that Lessing's pantheism was materialistic in that it thought of all Nature and God as one extended substance. For Jacobi, this was the result of the Enlightenment's devotion to reason and it would lead to atheism. Mendelssohn disagreed by asserting that pantheism was the same as theism.
Methods of explanation
An oft-cited feature of pantheism is that each individual human, being part of the Universe or nature, is part of God. One issue discussed by pantheists is how free will may exist in this framework. In answer, the following analogy is sometimes given (particularly by classical pantheists): "you are to God as an individual blood cell in your vein is to you." The analogy further maintains that while a cell may be aware of its own environs, and even has some choices (free will) between right and wrong (killing a bacterium, becoming malignant, or perhaps just doing nothing, among countless others), it likely has little conception of the greater being of which it is a part. Another way to understand this relationship is through the Hindu phrase, tat tvam asi - "that thou art", wherein the human soul/self or Atman is understood to be the same as God or Brahman - only people do not realize it. In this Hindu context, they believe that one must be liberated through enlightenment (moksha) in order to experience and fully understand this relationship - the part becomes no longer dissimilar from the whole.
Not all pantheists accept the idea of free will, with determinism being particularly widespread among naturalistic pantheists. Although individual interpretations of pantheism may suggest certain implications for the nature and existence of free will and/or determinism, pantheism itself does not include any requirement of belief either way. However, the issue is widely discussed, as it is in many other religions and philosophies.
Panentheism
Pantheism has features in common with panentheism, such as the idea that the Universe is part of God. Technically, the two are separate. Whereas pantheism finds God to be synonymous with nature, panentheism finds God to be greater than nature alone. Some find this distinction unhelpful, while others see it as a significant point of division. Many of the major faiths described as pantheistic could also be described as panentheistic, whereas naturalistic pantheism cannot (not seeing God as more than nature alone). For example, elements of both panentheism and pantheism are found in Hinduism. Certain interpretations of the Bhagavad Gita and Shri Rudram support this view.
Cosmotheism
While the term is rarely used, and is most often simply a synonym for Pantheism, this unusual philosophy has been used rather differently, but in all cases, the feeling was that God was something created by man, perhaps even an end state of human evolution, through social planning, eugenics and other forms of genetic engineering.
H. G. Wells subscribed to a form of Cosmotheism, which he called the "world brain" (from a book of essays by the same name he printed in 1937, one of which details the creation of a Library-encyclopedia hybrid), and detailed even more in his book God the Invisible King (in which he proscribes mankind to set up a socialist system, structuring itself on social and genetic statistics, education, and eugenics, ideally someday equating itself and possibly even merging with and conquering the Pantheist god itself. See: Omega Point) and there were also some sections of his work Outline of History, which reflected this belief and his finding it in the teachings of Jesus and Siddhartha. His book Shape of Things to Come (and the 1936 film Things to Come) also reflects this, in which mankind, surviving an apocalyptic war and an extended Feudal period, unites to form a collectivist Utopia.
In modern 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. He felt that God was something which did not exist before man, and was a secular entity which the rebuilding of the Jewish Temple in Jerusalem had an instrumental role in "inventing".
