 contributed to the expansion of the term to refer to disbelief in all deities, though it remains common in Western society to describe atheism as simply "disbelief in God". Most recently, there has been a push in certain philosophical circles to redefine atheism as the "absence of belief in deities", rather than as a belief in its own right; this definition has become popular in atheist communities, though its mainstream usage has been limited.

Definitions and distinctions

Writers disagree how best to define and classify atheism, contesting what supernatural entities it applies to, whether it is an assertion in its own right or merely the absence of one, and whether it requires a conscious, explicit rejection. A variety of categories have been proposed to try to distinguish the different forms of atheism.

Range

Some of the ambiguity and controversy involved in defining atheism arises from difficulty in reaching a consensus for the definitions of words like deity and god. The plurality of wildly different conceptions of god

; conversely, the ancient Romans accused Christians of being atheists for not worshipping the pagan deities. In the 20th century this view has fallen into disfavor as theism has come to be understood as encompassing belief in any divinity.

Atheism is most contrasted with agnosticism

An agnostic atheist is atheistic because he or she does not believe in the existence of any deity and is also agnostic because he or she does not claim to have definitive knowledge that a deity does not exist....

Implicit vs. explicit

Definitions of atheism also vary in the degree of consideration a person must put to the idea of gods to be considered an atheist. Atheism has sometimes been defined to include the simple absence of belief that any deities exist. This broad definition would include newborns and other people who have not been exposed to theistic ideas. As far back as 1772, Baron d'Holbach
Baron d'Holbach

 (1979) suggested that: "The man who is unacquainted with theism is an atheist because he does not believe in a god. This category would also include the child with the conceptual capacity to grasp the issues involved, but who is still unaware of those issues. The fact that this child does not believe in god qualifies him as an atheist." Smith coined the term implicit atheism to refer to "the absence of theistic belief without a conscious rejection of it" and explicit atheism to refer to the more common definition of conscious disbelief.

In Western civilization, the view that children are born atheist is relatively recent. Before the 18th century, the existence of God was so universally accepted in the western world that even the possibility of true atheism was questioned. This is called theistic innatism

According to this categorization, anyone who is not a theist is either a weak or a strong atheist. The terms weak and strong are relatively recent; however, the equivalent terms negative and positive atheism have been used in the philosophical literature and (in a slightly different sense) in Catholic apologetics.

 and suggested guidelines for a positive atheist philosophy, meaning one that promotes positive values. Positive atheism entails such things as a being morally upright, showing an understanding that religious people have reasons to believe, not proselytising or lecturing others about atheism, and defending oneself with truthfulness instead of aiming to 'win' any confrontations with outspoken critics.

Rationale


The broadest demarcation of atheistic rationale is between practical and theoretical atheism. The different forms of theoretical atheism each derive from a particular rationale or philosophical argument. In contrast, practical atheism requires no specific argument, and can include indifference to and ignorance of the idea of gods.

 with or without fully accepting or believing it."

Practical atheism can take various forms:
  • Absence of religious motivation—belief in gods does not motivate moral action, religious action, or any other form of action;
  • Active exclusion of the problem of gods and religion from intellectual pursuit and practical action;
  • Indifference—the absence of any interest in the problems of gods and religion; or
  • Unawareness of the concept of a deity.


Theoretical atheism


Theoretical, or contemplative, atheism explicitly posits arguments against the existence of gods, responding to common theistic arguments
Existence of God

Arguments for and against the existence of God have been proposed by scientists, philosophers, theologians, and others. In Philosophy terminology, "existence-of-God" arguments concern schools of thought on the epistemology of the ontology of God....

. The theoretical reasons for rejecting gods assume various psychological, sociological, metaphysical, and epistemological forms.

Epistemological arguments

It is difficult to quantify the number of atheists in the world. Respondents to religious-belief polls may define "atheism" differently or draw different distinctions between atheism, non-religious beliefs, and non-theistic religious and spiritual beliefs. In addition, people in some regions of the world refrain from reporting themselves as atheists to avoid social stigma, discrimination, and persecution.

 (among others) assert that behaving ethically only because of divine mandate is not true ethical behavior but merely blind obedience. Baggini argues that atheism is a superior basis for ethics, claiming that a moral basis external to religious imperatives is necessary to evaluate the morality of the imperatives themselves - to be able to discern, for example, that "thou shalt steal" is immoral even if one's religion instructs it - and that atheists, therefore, have the advantage of being more inclined to make such evaluations. The contemporary British political philosopher Martin Cohen has offered the more historically telling example of Biblical injunctions in favour of torture and slavery as evidence of how religious injunctions follow political and social customs, rather than vice versa, but also noted that the same tendency seems to be true of supposedly dispassionate and objective philosophers. Cohen extends this argument in more detail in Political Philosophy from Plato to Mao in the case of the Koran which he sees as having had a generally unfortunate role in preserving medieval social codes through changes in secular society.
