Comprehensive definition of atheism
Atheism, in general, the critique and denial of metaphysical beliefs in God or spiritual beings. As such, it is usually distinguished from theism, which affirms the reality of the divine and often seeks to demonstrate its existence. Atheism is also distinguished from agnosticism, which leaves open the question whether there is a god or not, professing to find the questions unanswered or unanswerable.
The dialectic of the argument between forms of belief and unbelief raises questions concerning the most perspicuous delineation, or characterization, of atheism, agnosticism, and theism. It is necessary not only to probe the warrant for atheism but also carefully to consider what is the most adequate definition of atheism. This article will start with what have been some widely accepted, but still in various ways mistaken or misleading, definitions of atheism and move to more adequate formulations that better capture the full range of atheist thought and more clearly separate unbelief from belief and atheism from agnosticism. In the course of this delineation the section also will consider key arguments for and against atheism. Atheism as rejection of religious beliefs
A central, common core of Judaism, Christianity, and Islam is the affirmation of the reality of one, and only one, God. Adherents of these faiths believe that there is a God who created the universe out of nothing and who has absolute sovereignty over all his creation; this includes, of course, human beings—who are not only utterly dependent on this creative power but also sinful and who, or so the faithful must believe, can only make adequate sense of their lives by accepting, without question, God’s ordinances for them. The varieties of atheism are numerous, but all atheists reject such a set of beliefs.
Atheism, however, casts a wider net and rejects all belief in “spiritual beings,” and to the extent that belief in spiritual beings is definitive of what it means for a system to be religious, atheism rejects religion. So atheism is not only a rejection of the central conceptions of Judaism, Christianity, and Islam; it is, as well, a rejection of the religious beliefs of such African religions as that of the Dinka and the Nuer, of the anthropomorphic gods of classical Greece and Rome, and of the transcendental conceptions of Hinduism and Buddhism. Generally atheism is a denial of God or of the gods, and if religion is defined in terms of belief in spiritual beings, then atheism is the rejection of all religious belief.
It is necessary, however, if a tolerably adequate understanding of atheism is to be achieved, to give a reading to “rejection of religious belief” and to come to realize how the characterization of atheism as the denial of God or the gods is inadequate. Atheism and theism
To say that atheism is the denial of God or the gods and that it is the opposite of theism, a system of belief that affirms the reality of God and seeks to demonstrate his existence, is inadequate in a number of ways. First, not all theologians who regard themselves as defenders of the Christian faith or of Judaism or Islam regard themselves as defenders of theism. The influential 20th-century Protestant theologian Paul Tillich, for example, regards the God of theism as an idol and refuses to construe God as a being, even a supreme being, among beings or as an infinite being above finite beings. God, for him, is “being-itself,” the ground of being and meaning. The particulars of Tillich’s view are in certain ways idiosyncratic, as well as being obscure and problematic, but they have been influential; and his rejection of theism, while retaining a belief in God, is not eccentric in contemporary theology, though it may very well affront the plain believer.
Second, and more important, it is not the case that all theists seek to demonstrate or even in any way rationally to establish the existence of God. Many theists regard such a demonstration as impossible, and fideistic believers (e.g., Johann Hamann and Søren Kierkegaard) regard such a demonstration, even if it were possible, as undesirable, for in their view it would undermine faith. If it could be proved, or known for certain, that God exists, people would not be in a position to accept him as their sovereign Lord humbly on faith with all the risks that entails. There are theologians who have argued that for genuine faith to be possible God must necessarily be a hidden God, the mysterious ultimate reality, whose existence and authority must be accepted simply on faith. This fideistic view has not, of course, gone without challenge from inside the major faiths, but it is of sufficient importance to make the above characterization of atheism inadequate.

Finally, and most important, not all denials of God are denials of his existence. Believers sometimes deny God while not being at all in a state of doubt that God exists. They either willfully reject what they take to be his authority by not acting in accordance with what they take to be his will, or else they simply live their lives as if God did not exist. In this important way they deny him. Such deniers are not atheists (unless we wish, misleadingly, to call them “practical atheists”). They are not even agnostics. They do not question that God exists; they deny him in other ways. An atheist denies the existence of God. As it is frequently said, atheists believe that it is false that God exists, or that God’s existence is a speculative hypothesis of an extremely low order of probability.
Yet it remains the case that such a characterization of atheism is inadequate in other ways. For one it is too narrow. There are atheists who believe that the very concept of God, at least in developed and less anthropomorphic forms of Judeo-Christianity and Islam, is so incoherent that certain central religious claims, such as “God is my creator to whom everything is owed,” are not genuine truth-claims; i.e., the claims could not be either true or false. Believers hold that such religious propositions are true, some atheists believe that they are false, and there are agnostics who cannot make up their minds whether to believe that they are true or false. (Agnostics think that the propositions are one or the other but believe that it is not possible to determine which.) But all three are mistaken, some atheists argue, for such putative truth-claims are not sufficiently intelligible to be genuine truth-claims that are either true or false. In reality there is nothing in them to be believed or disbelieved, though there is for the believer the powerful and humanly comforting illusion that there is. Such an atheism, it should be added, rooted for some conceptions of God in considerations about intelligibility and what it makes sense to say, has been strongly resisted by some pragmatists and logical empiricists.
While the above considerations about atheism and intelligibility show the second characterization of atheism to be too narrow, it is also the case that this characterization is in a way too broad. For there are fideistic believers, who quite unequivocally believe that when looked at objectively the proposition that God exists has a very low probability weight. They believe in God not because it is probable that he exists—they think it more probable that he does not—but because belief is thought by them to be necessary to make sense of human life. The second characterization of atheism does not distinguish a fideistic believer (a Blaise Pascal or a Soren Kierkegaard) or an agnostic (a T.H. Huxley or a Sir Leslie Stephen) from an atheist such as Baron d’Holbach. All believe that “there is a God” and “God protects humankind,” however emotionally important they may be, are speculative hypotheses of an extremely low order of probability. But this, since it does not distinguish believers from nonbelievers and does not distinguish agnostics from atheists, cannot be an adequate characterization of atheism.
