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.
IgnosticismIgnosticism or igtheism is the idea that the question of the existence of God is meaningless because the word "God" has no coherent and unambiguous definition. The term ignosticism was coined in 1964 by Sherwin Wine, a rabbi and a founding figure of Humanistic Judaism. Ignosticism and theological noncognitivism are similar although whereas the ignostic says "every theological position assumes too much about the concept of God", the theological noncognitivist claims to have no concept whatever to label as "a concept of God", but the relationship of ignosticism to other nontheistic views is less clear.
Agnostic atheismAgnostic atheism or atheistic agnosticism is a philosophical position that encompasses both atheism and agnosticism. Agnostic atheists are atheistic because they do not hold a belief in the existence of any deity, and are agnostic because they claim that the existence of a demiurgic entity or entities is either unknowable in principle or currently unknown in fact. The agnostic atheist may be contrasted with the agnostic theist, who believes that one or more deities exist but claims that the existence or nonexistence of such is unknown or cannot be known.
IetsismIetsism (ietsisme (itsˈɪsmə) – "somethingism") is an unspecified belief in an undetermined transcendent reality. It is a Dutch term for a range of beliefs held by people who, on the one hand, inwardly suspect – or indeed believe – that "there must be something undefined beyond the mundane and that which can be known or can be proven", but on the other hand do not accept or subscribe to the established belief system, dogma or view of the nature of a deity offered by any particular religion.
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.
Conceptions of GodConceptions of God in monotheist, pantheist, and panentheist religions – or of the supreme deity in henotheistic religions – can extend to various levels of abstraction: as a powerful, personal, supernatural being, or as the deification of an esoteric, mystical or philosophical entity or category; as the "Ultimate", the summum bonum, the "Absolute Infinite", the "Transcendent", or Existence or Being itself; as the ground of being, the monistic substrate, that which we cannot understand; and so on.
AgnosticismAgnosticism is the view or belief that the existence of God, of the divine or the supernatural is unknown or unknowable. It can be categorized as an indifference or absence of firm beliefs in theistic religions and atheism on that basis. Another definition provided is the view that "human reason is incapable of providing sufficient rational grounds to justify either the belief that God exists or the belief that God does not exist.
Existence of GodThe existence of God (or more generally, the existence of deities) is a subject of debate in theology, philosophy of religion and popular culture. A wide variety of arguments for and against the existence of God or deities can be categorized as logical, empirical, metaphysical, subjective or scientific. In philosophical terms, the question of the existence of God or deities involves the disciplines of epistemology (the nature and scope of knowledge) and ontology (study of the nature of being or existence) and the theory of value (since some definitions of God include "perfection").
IrreligionIrreligion is the neglect or active rejection of religion and, depending on the definition, a simple absence of religion. Irreligion takes many forms, ranging from the casual and unaware to full-fledged philosophies such as atheism and agnosticism, secular humanism and antitheism. Social scientists tend to define irreligion as a purely naturalist worldview that excludes a belief in anything supernatural. The broadest and loosest definition, serving as an upper limit, is the lack of religious identification, though many non-identifiers express metaphysical and even religious beliefs.
Apophatic theologyApophatic theology, also known as negative theology, is a form of theological thinking and religious practice which attempts to approach God, the Divine, by negation, to speak only in terms of what may not be said about the perfect goodness that is God. It forms a pair together with cataphatic theology, which approaches God or the Divine by affirmations or positive statements about what God is. The apophatic tradition is often, though not always, allied with the approach of mysticism, which aims at the vision of God, the perception of the divine reality beyond the realm of ordinary perception.
