Monistic Religion

Monism is the metaphysical view that all is of one essential essence, substance or energy. Monism is to be distinguished from dualism, which holds that ultimately there are two kinds of substance, and from pluralism, which holds that ultimately there are many kinds of substance. Monism is often seen in relation to pantheism, panentheism, and an immanent God. Monism is often seen as partitioned into three different kinds:

1. Physicalism or materialism, which holds that only the physical is real, and that the mental can be reduced to the physical
2. Idealism or phenomenalism, which holds the converse
3. Neutral monism, which holds that both the mental and the physical can be reduced to some sort of third substance, or energy

Just as we no longer follow the ancient Greeks in saying that all matter is composed of earth, air, water, and fire, people of the future will no longer speak of "beliefs", "desires", and other mental states. A subcategory of eliminativism is radical behaviourism, a view held by B. F. Skinner.) Anomalous monism, a position proposed by Donald Davidson in the 1970s as a way to resolve the Mind-body problem. It could be considered (by the above definitions) either physicalism or neutral monism.

Davidson holds that here is only physical matter, but that all mental objects and events are perfectly real and are identical with (some) physical matter. But physicalism retains a certain priority, inasmuch as

1. All mental things are physical, but not all physical things are mental
2. (As John Haugeland puts it) Once you take away all the atoms, there's nothing left.

For some, monism may also have religious/spiritual implications. Recognizing this, some inveigh against the 'dangers of monism,' asserting that in order to resolve all things to a single substrate, one dissolves God in the process.Others say that the "single substrate is God. Theological arguments can be made for this within Christianity for example the Roman Catholic doctrine of "divine simplicity", as well as in many other religions (Hinduism, Ayyavazhi and Judaism in particular).Historically, monism has been promoted in spiritual terms on several occasions, notably by Ernst Haeckel. To the dismay of most modern observers, Haeckel's various ideas often had components of social darwinism and scientific racism.
