Theism and atheism aren’t merely epistemic stances concerning belief in god, but they’re robust philosophical positions that contain an analytic component. Analytic theism will ask the following questions: what is theism?; what or who is god? Analytic atheism will share the latter question insofar as the theist attempts to provide answers to that question.
Atheists, however, will not always agree with the answers provided by theists. A theist may respond to the first question and say that god is existence. An atheist might object by saying that such a definition is inconsistent with what theists commonly profess and that what they usually profess is much more elementary. God, for example, is man-like. He is pleased or displeased; given the latter, he is prone to anger. Furthermore, he purportedly has properties that can’t be attributed to mere existence: he’s omniscient, omnipotent, eternal. The atheist could also respond by stating that defining god as existence is much too vague. The aim of a definition is description; this definition, however, fails to describe what is meant by god.
Analytic atheism also attempts to answer the question: what is atheism? To accomplish this, however, the normative component has to be consulted. The analytic component, which is discussed below, will provide theories of atheism or more simply, accounts of what atheism should be—therefore providing possible answers to the question of normative atheism. The analytic component is therefore responsible for determining which account best captures what atheism is or alternatively, what an atheist is.
What an atheist is is perhaps best defined by the approach he/she chooses. The approach chosen or a combination of these approaches might help us to arrive at a better definition of atheism. There’s fallibilism, deductive atheology, and inductive atheology. The latter two are encompassed by evidentialism. This position is arguably most familiar to modern atheists:
[A]theists have taken the view that whether or not a person is justified in having an attitude of belief towards the proposition, “God exists,” is a function of that person’s evidence. “Evidence” here is understood broadly to include a priori arguments, arguments to the best explanation, inductive and empirical reasons, as well as deductive and conceptual premises. An asymmetry exists between theism and atheism in that atheists have not offered faith as a justification for non-belief. That is, atheists have not presented non-evidentialist defenses for believing that there is no God.1
A priori arguments fall in the purview of deductive atheology. Such atheists would argue that the traditional view of god is incoherent. Such a god isn’t possible on this view. The characteristics god purportedly has are contradictory either in and of themselves or when one attempts to reconcile them. Take for example J.L Mackie’s explication of the Omnipotence Paradox: “can an omnipotent being make things which he cannot subsequently control? Or, what is practically equivalent to this, can an omnipotent being make rules which then bind himself?”2 This is a more generalized version of the Omnipotence Paradox, which usually asks: can god create a stone he cannot lift? Therefore, the paradox can be viewed as an argument attempting to show that omnipotence is incoherent in and of itself. The argument attempts to accomplish this by dividing omnipotence into two components, which I’ll call functional and physical. Functional omnipotence is the capacity to will anything whilst physical omnipotence is the capacity to do anything. Therefore, the argument attempts to show that it’s possible that god could will something he cannot do—in Mackie’s case, will something that he can’t control or in the general case, will the existence of a stone so heavy that he cannot complete the particular task of lifting it.
Another route such an atheist takes is the attempt to show that any given attributes of god are irreconcilable.
The combination of omnipotence and omniscience have received a great deal of attention. To possess all knowledge, for instance, would include knowing all of the particular ways in which one will exercise one’s power, or all of the decisions that one will make, or all of the decisions that one has made in the past. But knowing any of those entails that the known proposition is true. So does God have the power to act in some fashion that he has not foreseen, or differently than he already has without compromising his omniscience? It has also been argued that God cannot be both unsurpassably good and free.3
Another route available to such an atheist is to argue that we haven’t been offered an adequate concept of god.4 Concepts of god are often relative to this or that religion or subjective to this or that individual. Such concepts often do not agree with one another.
Perhaps the final route such an atheist can take is to argue that the failure of theistic arguments entails atheism. In other words, since arguments for god fail, it is reasonable to hold that god doesn’t exist. Such an atheist, for example, will argue that since the Kalam Cosmological Argument fails to prove that god created the universe, we should believe that such an agent didn’t create the universe. Alternatively, she will argue that since the Ontological Argument fails to show the existence of a necessary being, this being is instead impossible. Whether or not these arguments hold are of no interest at the time. This is, however, how such an atheist will proceed.
An atheist operating under inductive atheology has several possible approaches. Whether or not one can prove a negative is too tangential a topic to cover here, but assuming it’s possible, one could offer Michael Martin’s argument:
P1 [A]ll the available evidence used to support the view that X exists is shown to be inadequate; and
P2 X is the sort of entity that, if X exists, then there is a presumption that would be evidence adequate to support the view that X exists; and
P3 this presumption has not been defeated although serious efforts have been made to do so; and
P4 the area where evidence would appear, if there were any, has been comprehensively examined; and
P5 there are no acceptable beneficial reasons to believe that X exists.5
What makes this argument inductive is P3 and P4. P3 and P4 hold hitherto and thus, there’s the tacit assumption that they will hold going forward. In other words, that the future will resemble the past.
Naturalism is another argument available to an atheist operating under inductive atheology. This is, in fact, the prevalent approach among modern day atheists. Atheists may disagree on the details and therefore, espouse different sorts of naturalism. However, the more prominent forms are metaphysical and methodological. Methodological naturalism has two primary forms: constructive and deflationary. Deflationary is based on—not exclusively—the Natural Ontological Attitude (NOA). Arthur Fine describes it as follows:
I certainly trust the evidence of my senses, on the whole with regard to the existence and features of everyday objects. And I have similar confidence in the “cheek, double-check, check, tripe-check” of scientific investigation…So if scientists tell me that there really are molecules and atoms, and…who knows maybe even quarks, then so be it. I trust them and, thus, must accept that there really are such things with their attendant properties and relations.6
NOA is an alternative to scientific realism and anti-realism. “Both realism and anti-realism add an unwanted philosophical gloss to science.”7 Therefore, the position neither agrees with scientific realism nor anti-realism. At first glance, NOA may sound exactly like scientific realism, but there are key differences that should be considered (e.g. the correspondence theory of truth doesn’t factor into Fine’s NOA). Constructive naturalism differs from NOA because it “involves commitment to a definite method for resolving ontological matters.”8 Such a naturalist may make use of, for example, Quine’s Naturalized Epistemology.
Metaphysical naturalism absorbs methodological naturalism. The view could be defined as follows:
Metaphysical naturalism seeks to explain every feature of our reality through only natural entities and causes, without the need of god(s) or the supernatural in any part of one’s worldview and life philosophy. In other words, a “big picture” explanation of reality can be reached without any appeal to religion, making religions such as Christianity unnecessary and extraneous to answering the big questions in life.9
Metaphysical naturalism is a robust worldview that often requires lengthy elucidation. This has been done by, for example, Richard Carrier who states:
[I]f you want to know what we believe on almost any subject, you need merely read authoritative works on science and history—which means, first, college-level textbooks of good quality and, second, all the other literature on which their contents are based. The vast bulk of what you find there we believe in. The evidence and reason for those beliefs is presented in such works and need not be repeated…10
Where such authorities are silent, metaphysical naturalism is capable of providing possible answers. Take, for instance, the mind or morality. Metaphysical naturalism can offer cogent explanations in regards to both. For instance, with respect to the mind, some naturalists have offered some version of supervenience.
On fallibilism, an atheist can argue that a theist has come to a given conclusion because he hasn’t considered all the relevant evidence.10 In fact, part of this attitude plays a role in discussions between theists and atheists. Theists, generally speaking, make it quite obvious that they aren’t aware of all of the relevant evidence. William Lane Craig, for example, employs a perfunctory grasp of cosmology in order to support his KCA. It’s reasonable to conclude that if he were aware of all of the evidence, his conclusion would be different. Unfortunately, this might be too generous. Craig has been made aware of the evidence and regardless of the fact, he still chooses to endorse the KCA. So in some cases, it’s not just that a theist’s knowledge is fallible, but it’s that they disregard the fact and do not care to correct it.
Now that I’ve surveyed analytic atheism, it is time now to discuss the normative component of atheism. The normative question is akin to normativity as commonly understood in philosophy. Take, for instance, normative jurisprudence. The question of normative jurisprudence is: what should law be? In like manner, the question of normative atheism is: what should atheism be? Or, what should an atheist be?
Clearly, given that a Buddhist can be considered an atheist, atheism should be more than simply lack of belief in gods. To see what atheism should be or what an atheist should be, it is required that we distinguish the atheist and the Buddhist. We are required to account for their differences. These differences will help us see why one identifies as an atheist whilst the other identifies as a Buddhist.
Buddhism, however, divides into two primary schools: Mahayana and Theravada. These two schools divide further within themselves. We therefore have to narrow our focus. In other words, we have to focus on a certain type of Buddhist to see where the differences are. Thus, we will focus on Tibetan Buddhism.
Tibetan Buddhism pertains to Mahayana Buddhism. It, however, incorporates tantric and shamanic aspects—the latter of which it appropriated from the ancient Tibetan religion, Bon. For this reason, it is often conflated with or mistaken for a minor school of Buddhism, Vajrayana.12 Tantra for instance “brings Tibetan Buddhism a magical element and a rich portfolio of heavenly beings. It also brings a wide variety of spiritual techniques such as mantras, mandalas, ceremonies, and many varieties of yoga.”13
Without going any further into Tibetan Buddhism, does an atheist, as normally construed, believe in magical elements and heavenly beings? Does she participate in rituals or believe in their efficacy? The obvious answer is no. Therefore, when someone refers to Buddhism as atheistic, they mean only to point out that Buddhism doesn’t offer a concept of god. It isn’t, however, atheistic in a normative sense. Given this, what then should atheism be? Alternatively, what should an atheist be?
Given the analytic component surveyed earlier, an atheist could adhere to any of the following theories: default atheism, natural atheism, or pluralistic atheism. Default atheism makes use of deductive atheology and cites that since the arguments for god fail, god cannot exist. Or such an atheist could state that since there’s no evidence for god, god doesn’t exist. They are therefore an atheist by default. Natural atheism, on the other hand, piggybacks on naturalism. Since all empirical explanations are naturalistic, the supernatural doesn’t factor into what she believes in. She is therefore a natural atheist.
Pluralistic atheism is what I want to offer. If any of the above methodologies or positions sound familiar to you, it’s because atheists are a diverse group of people that, in fact, employ some of these methodologies and therefore, adopt such positions. They will therefore have diverse ways of grounding their atheism, if such a project even interests them. Default atheists, for example, might not care enough about the question. Others not only care about the question of god, but they also care about what results from belief in god; given this, they make an effort to justify their non-belief in such entities. Pluralistic atheism therefore makes some use of every method discussed above. It doesn’t favor deductive over inductive atheology or vice versa. It can and very often does incorporate naturalism into its justification. It can and does invoke fallibilism in discussions with theists.
So given this, the question of what atheism is is answered by what atheism should be. Since pluralism incorporates naturalism, the question of natural atheism is essentially the combination of those questions. That is to say that what atheism is is identical to what atheism should be. On naturalism and therefore, on pluralism, the question of what atheism is is clearly answered once we consider what atheism should be.
Atheism should be more than the lack of belief in gods. It should also, by extension, be the lack of belief in the authority of religious texts, the efficacy of rituals, the purported existence of metaphysical entities such as angels and transcendent ancestors, magic, and even aspects of religious culture. Given the latter, atheists shouldn’t wear some traditional attire. The other items are pretty straightforward. The reason they’re straightforward goes back to our analytic component.
If the arguments for god fail or if naturalism is true or if a theist has incomplete knowledge and thus a false conclusion, we have good reason to reject the entirety of the system they’re offering. If we reject the Judeo-Christian god, then we are compelled to reject the Judeo-Christian portraits of heaven and hell along with the entities said to reside in these places. We must also reject the so called power of prayer and the utility of fasting. Also, given the authority of science and the evidence it has presented us with, the purported authority of the Bible becomes suspect. It is more suspect still when one considers what history tells us. Therefore, atheism should be and therefore is the lack of belief in gods and anything that may be tied to them: religious texts, rituals, metaphysical entities and places, and cultural aspects.
What I’ve attempted to do here is show that analytic atheism entails normative atheism. This is the case because on pluralism, naturalism is featured. Natural atheism, like natural law, answers the questions of analytic and normative atheism as one. The question of analytic jurisprudence is what is law whilst the question of normative jurisprudence is what should the law be. A natural law theory like, for instance, Leibniz’s will answer both questions simultaneously. This, I have argued, is what happens with atheism.
Atheism is the default position. Belief is like an achieved rather than ascribed status. At birth, you are either a son or daughter; this status is ascribed. The status of Christian is achieved given that one has to go through some motions to become one—e.g. baptism. Atheism, on the other hand, is like an ascribed status. At birth, you are neither Christian nor Muslim nor Hindu. These labels may be given to you by devout parents, but they aren’t true given that you have no way of formulating a sophisticated worldview. Atheism is also the natural position. Given naturalism, gods cannot feature into any explanation in and of the universe. One can, of course, offer ad hoc rationalization, but this is not parsimonious. It adds to an explanation that is already complete. Therefore, given natural atheism and consequently pluralistic atheism, what atheism is is exactly what atheism should be. If we answer the latter, we answer the former.
