AtheismAtheism, in the broadest sense, is an absence of belief in the existence of deities. Less broadly, atheism is a rejection of the belief that any deities exist. In an even narrower sense, atheism is specifically the position that there no deities. Atheism is contrasted with theism, which in its most general form is the belief that at least one deity exists. The first individuals to identify themselves as atheists lived in the 18th century during the Age of Enlightenment.
Theological noncognitivismTheological noncognitivism is the non-theist position that religious language, particularly theological terminology such as "God", is not intelligible or meaningful, and thus sentences like "God exists" are cognitively meaningless. It may be considered synonymous with ignosticism (also called igtheism), a term coined in 1964 by Sherwin Wine, a rabbi and a founding figure of Humanistic Judaism. Theological noncognitivists argue in different ways, depending on what one considers the "theory of meaning" to be.
Spectrum of theistic probabilityPopularized by Richard Dawkins in The God Delusion, the spectrum of theistic probability is a way of categorizing one's belief regarding the probability of the existence of a deity. J. J. C. Smart argues that the distinction between atheism and agnosticism is unclear, and many people who have passionately described themselves as agnostics were in fact atheists. He writes that this mischaracterization is based on an unreasonable philosophical skepticism that would not allow us to make any claims to knowledge about the world.
GodIn monotheistic thought, God is usually viewed as the supreme being, creator, and principal object of faith. In polytheistic thought, a god is "a spirit or being believed to control some part of the universe or life and often worshipped for doing so, or something that represents this spirit or being". Belief in the existence of at least one god is called theism. Views regarding God vary considerably. Many notable theologians and philosophers have developed arguments for and against the existence of God.
Negative and positive atheismNegative atheism, also called weak atheism and soft atheism, is any type of atheism where a person does not believe in the existence of any deities but does not necessarily explicitly assert that there are none. Positive atheism, also called strong atheism and hard atheism, is the form of atheism that additionally asserts that no deities exist. Sometimes positive atheism goes by the term gnostic atheism to contrast with agnostic atheism, which is more correlated with weak atheism, and to stand opposite Gnostic theism on simple charts mapping different belief systems.
