Acosmism, in contrast to pantheism, denies the reality of the universe, seeing it as ultimately illusory, (the prefix "a-" in Greek meaning negation; like "un-" in English), and only the infinite unmanifest Absolute as real.
This philosophy begins with the premise that there is only one Reality, which is infinite, non-dual, blissful, etc. Yet the phenomenal [...]

Agnosticism (from the Greek "a," meaning "without," and Gnosticism or "gnosis," meaning knowledge) means "unknowable," and is the philosophical view that the truth value of certain claims, particularly theological claims regarding metaphysics, afterlife or the existence of God, god(s), or deities, is unknown or, depending on the form of agnosticism, inherently unknowable.
Agnostics claim either that [...]

Many self-described atheists share [...]

Binitarianism is a theology of two in one God, as opposed to one (unitarianism) or three (trinitarianism). Classically, it is understood as strict monotheism ? that is, that God is an absolutely single being; and yet there is a “twoness” in God. At times, this monotheism drifted toward a “twoness” of God: that is, two [...]

Deism is a religious philosophy and movement that became prominent in England, France, and the United States in the 17th and 18th centuries. Deists typically reject supernatural events (prophecy, miracles) and divine revelation prominent in organized religion, along with holy books and revealed religions that assert the existence of such things. Instead, deists hold that [...]

The notion of dystheism is closely related to theodicy (the problem of evil, the Euthyphro dilemma).
Terminology
Eutheism and dystheism are straightforward Greek formations paralleling [...]
