Arguments from Naturalism against Theism

To naturalize religion, we must identify what religion is, and what aspects of it we are trying to explain. In this paper, religious social institutional behavior is the explanatory target, and an explanatory hypothesis based on shared primate social dominance psychology is given. The argument is that various religious features, including the high status afforded the religious, and the high status afforded to deities, are an expression of this social dominance psychology in a context for which it did not evolve: (...) high-density populations made possible by agriculture.

Human beings are social animals, not solitary ones. Morality is an instinct we have because it helps us socialize, live together harmoniously. This paper reviews how the evolution of morality and other mental functions associated with our survival and sociality gave rise to cultural behavior among the small groups of humans during the Palaeolithic period when the tribe was personified as a supernatural identity and guardian, a totem, an ancestor and ultimately a god. Loyalty to the tribe required loyalty to (...) the tribal god representing the tribe. Preservation of the tribe meant mistrust of other tribes and their gods. The merging of small groups rendered obsolete the tribal, locally cultural conception of religion, but it persisted as monotheism in the imperial stage of society from about 2000 BC, becoming the world religions. Today’s empires are global, and a belief system modelled on local tribes in competition is naïve divisive. Out-group hatred is more of a threat than any in-group moral benefits, and they too are disappearing with the failure to preserve small group coherence, and justice and fairness in capitalist society. The moral failure of imperial religion on the urban and global scale is the “Death of God”. Humans now cannot afford the moral laziness of constantly appealing to a supernatural totem in an otherwise do-nothing religion. Imperial religion was and still is a tool of the political right, used to manipulate us. Yet Christ offered an ethical scheme that is essentially a practical morality of mutual lovingkindness which does not require a supernatural God. It is Secular Christianity, a world view any scientist and atheist could adopt without compromise, and most Christians should. (shrink)

This paper considers the question of “atheism” as it arises in Hume’s _Dialogues_. It argues that the concept of “atheism” involves several signficiant ambiguities that are indicative of philosophical and interpretive disagreements of a more substantial nature. It defends the view that Philo’s general sceptical orientation accurately represents Hume’s own “irreligious” and “atheistic” commitments, both in the _Dialogues_ and in his other (“earlier”) writings. While Hume was plainly a “speculative atheist”, his “practical atheism” was targeted more narrowly against “superstition” - (...) as opposed to deism or religion of a more “philosophical” kind.

This introduction provides a brief overview of the issues and arguments that arise in Hume's _Dialogues concerning Natural Religion_ (1779). It also provides a few brief comments relating to the historical context in which this text should be interpreted , as well as an account of the place of the _Dialogues_ in relation to Hume's other philosophical works.

The Cognitive Science of Religion represents a contemporary attempt at a naturalistic explanation of religion. There is debate as to whether its account of how religious beliefs arise is reconcilable with the religious account, which holds that religious beliefs are caused by God. In my paper, I argue that these two accounts cannot be reconciled when it comes to the specific question of how Christian religious beliefs arise if one accepts an important theological doctrine of the supernaturality of Christian belief. (...) This doctrine implies that there can be no natural explanation for how Christian beliefs arise because they are a gift of divine grace. This leads to a conundrum for Christian theists: they can either reject the CSR account of how their religious beliefs arise, or they can reject the supernaturality of Christian belief. I argue that the latter is preferable. I then draw on the work of the theologian Denis Edwards to illustrate how one can drop this doctrine without abandoning some other fundamental tenets of Christian theology. (shrink)

This paper discusses a wide range of anti-naturalistic argument from reason due to Balfour, Haldane, Joad, Lewis, Taylor, Moreland, Plantinga, Reppert, and Hasker. I argue that none of these arguments poses a serious challenge to naturalists who are identity theorists. Further, I argue that some of these arguments do not even pose prima facie plausible challenges to naturalism. In the concluding part of my discussion, I draw attention to some distinctive differences between Hasker’s anti-naturalistic arguments and the other anti-naturalistic arguments (...) mentioned above.

Atheism Considered is a systematic presentation of challenges to the existence of a higher power. Rather than engage in polemic against a religious worldview, C.M. Lorkowski charitably refutes the classical arguments for the existence of god, pointing out flaws in their underlying reasoning and highlighting difficulties inherent to revealed sources. In place of a theistic worldview, he argues for adopting a naturalistic one, highlighting naturalism’s capacity to explain world phenomena and contribute to the sciences. Lorkowski demonstrates that replacing theism with (...) naturalism, contra popular assumptions, sacrifices nothing in terms of ethics or meaning. Instead, morality ultimately proves more important than religion and does not rely on it. Appropriate for classroom use, this book is meant to cultivate understanding, tolerance, and fruitful dialogue between believers and nonbelievers. (shrink)

Several metaphysical naturalists argue that the success of science, together with the claim that scientists adhere to methodological naturalism, amounts to strong evidence for metaphysical naturalism. I call this the scientific-success argument. It is argued that the scientific-success argument is similar to the no-miracles argument for realism in philosophy of science. On the no-miracles argument, the success of science is taken as strong evidence that scientific theories are true. Based on this similarity, some considerations relevant to one argument may also (...) be relevant to the other. One particular consideration is explored. The selectionist response to the no-miracles argument states that on an evolutionary model of science, in which scientific theories are accepted only after surviving a rigorous selection process, the no-miracles argument fails. The selectionist response also applies to the scientific-success argument. If scientific theories are selected for success, we do not need to explain the success of science by appealing to metaphysical naturalism. (shrink)

David Hume (1711-1776) is widely recognized as one of the most influential and significant critics of religion in the history of philosophy. There remains, nevertheless, considerable disagreement about the exact nature of his views. According to some, he was a skeptic who regarded all conjectures relating to religious hypotheses to be beyond the scope of human understanding – he neither affirmed nor denied these conjectures. Others read him as embracing a highly refined form of “true religion” of some kind. On (...) the other side of this spectrum, it is claimed that Hume was committed to atheism, although due to social conditions at the time, this had to be (thinly) concealed or masked. The aim of this article is to provide an overview of Hume’s core concerns and arguments on this subject and to provide the reader with a framework for interpreting and assessing his various contributions.

The argument and discussion in this paper begins from the premise that Hume was an atheist who denied the religious or theist hypothesis. However, even if it is agreed that that Hume was an atheist this does not tell us where he stood on the question concerning the value of religion. Some atheists, such as Spinoza, have argued that society needs to maintain and preserve a form of “true religion”, which is required for the support of our ethical life. Others, (...) such as D’Holbach have argued that religion is not only false it is pernicious and it should be eradicated. This paper argues that Hume rejected both these proposals, on the ground that they rest, in different ways, on excessively optimistic assumptions. The sensible, practical form of atheism that Hume defends has a more modest and realistic aim, which is simply to restrict and limit the most pernicious forms of religion. Understood this way, Hume’s practical atheism is very different from the forms of “old” atheism associated with Spinoza and D’Holbach, as well as from the “new atheism” of thinkers such as Dawkins and Dennett. -/- Reprinted in Paul Russell, "Recasting Hume and Early Modern Philosophy: Selected Essays" (New York: Oxford University Press, 2021): 340-383.

Alvin Plantinga has famously argued that the naturalist who accepts evolutionary theory has a defeater for all of her beliefs, including her belief in naturalism and evolution. Hence, he says, naturalism, when conjoined with evolution, is self defeating and cannot be rationally accepted. This is known as the evolutionary argument against naturalism (EAAN). However, Tyler Wunder (Religious Studies 51:391– 399, 2015) has recently shown that if the EAAN is framed in terms of objective probability and theism is assumed to be (...) non-contingent, then either theism is necessarily false or the EAAN is unsound. Neither option is attractive to the proponent of the EAAN. Perry Hendricks (Religious Studies 1–5, 2018) has responded to Wunder’s criticism, showing that the EAAN can be salvaged and, indeed, strengthened, by framing it in terms not of naturalism (N), but of a proposition that is entailed by N that is also consistent with theism. We will show that once Hendricks’ solution to Wunder’s objection is accepted, a puzzle ensues: if the EAAN provides the naturalist with a defeater for all of her beliefs, then an extension of it appears to provide God with a defeater for all of his beliefs. After bringing out this puzzle, we suggest several ways in which the proponent of the EAAN might solve it, but also show some potential weaknesses in these purported solutions. Whether the solutions to the puzzle that we consider ultimately succeed is unclear to us. (Translation: the authors disagree. One author thinks that the solutions (or,at least, some of them) that we consider do solve the puzzle while the other author does not.) However, it is clear to us that this is an issue that proponents of the EAAN need to address. (shrink)

The evidential problem of evil involves a rarely discussed challenge, namely the challenge of defending theism against the hypothesis of a morally indifferent creator. Our argument uses a Bayesian framework and it starts by showing that if the only alternative to classical theism is naturalistic atheism, then fine-tuning can render theism virtually certain, even in the face of evil. But if the alternatives include the hypothesis of a morally indifferent creator, theism is defeated even if the fine-tuning premise is accepted. (...) The resulting version of the evidential problem is unsolvable using the tools that are currently deployed by theists against evil. (shrink)

Evolutionary research on the biological fitness of groups has recently given a prominent value to the role that prosocial behaviors play in favoring a successful adaptation to ecological niches. Such a focus marks a paradigm shift. Early views of evolution relied on the notion of natural selection as a largely competitive mechanism for the achievement of the highest amount of resources. Today, evolutionists from different schools think that collaborative attitudes are an irremovable ingredient of biological change over time. As a (...) consequence, a number of researchers have been attracted by evolutionary studies of human behaviors. Some think that a continuity among prosocial attitudes of human beings and other social mammals can be detected, and that this fact has relevance for accounting for human morality. Others deny one or the other of these claims, or both. The papers in the present special issue address how these topics impact ethics and religion. (shrink)

Naturalists have many and diverse reasons for thinking that morality does not depend upon God. In this paper, I do not aim to give an exhaustive inventory of these reasons. Rather, I aim to give reason that emerge from the kind of naturalism that I accept. After explaining what I mean by "God", "morality" and "dependence", I note that, on the kind of naturalism that I accept, it is impossible that God exists. Unsurprisingly, therefore, I hold that it is impossible (...) that morality depends on God. While--as I go on to discuss--there are reasons to think that morality could not be dependent on anything else, I also canvass reasons for thinking that even theists should worry about the suggestion that morality might be dependent on God. -/- This chapter was published in a 'debate' book.

In this paper, I set out a fairly careful argument for the claim that natural reality ("the universe') does not have--and could not have--a cause. I being with a discussion of the question whether causal reality could have a cause. I claim that it is obvious that causal reality cannot have a cause. I then turn to a discussion of natural reality. I contend that, necessarily, natural reality exhausts causal reality: necessarily, natural reality and causal reality are one and the (...) same. Given that it is impossible for causal reality to have a cause, it follows immediately that natural reality cannot have a cause. -/- The paper is a chapter in a 'debate' book.

Proponents of the problem of animal suffering state that the great amount of animal death and suffering found in Earth’s natural history provides evidence against the truth of theism. In particular, philosophers such as Paul Draper have argued that regardless of the antecedent probability of theism and naturalism, animal suffering provides positive evidence for the truth of naturalism over theism. While theists have attempted to provide answers to the problem of animal suffering, almost none have argued that animal suffering and (...) death can be seen as positive evidence for theism. This essay will discuss several arguments from the writings of Thomas Aquinas that can be used to show that animal suffering and death are to be expected in theistic universes. In the first section, I discuss evidential arguments for naturalism from animal suffering. Next, I provide an overview of Aquinas’ arguments, particularly in Book II of the Summa Contra Gentiles. After this, I discuss the implications these arguments have for theistic universes. Finally, I conclude that these arguments refute evidential arguments for naturalism from animal suffering and also provide evidence that favors theism. (shrink)

Proponents of the problem of animal suffering claim that the millions of years of apparent nonhuman animal pain and suffering provides evidence against the existence of God. Neo-Cartesianism attempts to avoid this problem mainly by denying the existence of phenomenal consciousness in nonhuman animals. However, neo-Cartesian options regarding animal minds have failed to compel many. In this essay, I explore an answer to the problem of animal suffering inspired by the medieval theologian Thomas Aquinas. Instead of focusing on phenomenal consciousness, (...) the neo-Thomistic view of animal minds focuses on self-awareness. After proposing and providing evidence for this view, I conclude that nonhuman animal suffering is not morally significant. (shrink)

Contemporary philosophical debates about the competing merits of neurological and phenomenological approaches to understanding both psychiatric illness and religious experience—and, indeed, the relationship, if any, between psychiatric illness and religious experience. In this chapter, I propose that both psychiatric illness and religious experiences - at least in some of their diverse forms - are best understood phenomenologically in terms of radical changes in a person's 'existential feelings', in the sense articulated by Matthew Ratcliffe. If so, explanatory priority should be assigned (...) to phenomenology and not to neurology. (shrink)

The primary aim of this chapter is to evaluate whether considerations about a priori domains and abstract objects favor atheism over theism.

This is the concluding chapter of a debate book about the existence of God: *Theism and Atheism: Opposing Arguments in Philosophy* (Gale, 2019). The book has a large number of contributors on both sides. My chapter suggests one way of unifying the contributions that are made on the atheistic side.

This chapter is an invited contribution to a book on the naturalness of theistic belief. I start by considering ordinary usage of the term 'natural'. I then clarify how I shall use the terms 'naturalism', 'theism', 'worldview' and 'big picture'. I consider the demographic spread of commitment to theistic big pictures and naturalistic big pictures. I consider the distribution of happiness over those committed to theistic big pictures and naturalistic big pictures. I consider the distribution of reasons over those committed (...) to theistic big pictures and naturalistic big pictures. I consider whether intuitive considerations favour one kind of big picture over the other. As it often the case, I draw somewhat irenic conclusions from these considerations. (shrink)

Andrew Shephardson contends in Who’s Afraid of the Unmoved Mover that the combined postmodern objections of Carl A. Raschke, James K. A. Smith, and me, to natural theology, fail. Here I focus only on the issue of idolatry and natural theology, as one way of demonstrating a fundamental inadequacy characteristic of Shephardson’s rebuttal of postmodern challenges to evangelical appropriations of natural theology. I argue that contrary to Shephardson’s contention, Acts 17 does not support evangelical appropriations of natural theology, but operates (...) with a view of reason consistent with my postmodern one and opens postmodern possibilities for understanding natural revelation.

Religious exclusivism is the biggest threat for multi-religious society at the same time, ambivalent thoughts among religion in religious pluralism due to religious diversity often yields religious violence. In both of the extreme, (religious exclusivism and religious pluralism) there is the possibility of religious violence, i.e., religious riots, terrorism, mob lynching, and communalism. The objective of this paper is to discuss the significance of interreligious dialogue (IRD), its basic principle, how IRD will help us for addressing the problems of humanity (...) (i.e., Religious diversity and contradictory thoughts in major religions, Religious Dogma, superstition, and terrorism). If there is any biggest challenge for religion in the 21st century, is this one that how religion can deal with these problems and became a good tool for establishing peace and prosperity in the region.

In Who’s Afraid of the Unmoved Mover? Postmodernism and Natural Theology, I defend natural theology against its postmodern evangelical detractors, including Myron Bradley Penner. Penner rejects natural theology because it attempts to ground knowledge of God in human reason, and he claims that my treatment of Acts 17:16–34 is fatal to my argument. However, Penner does not engage my explication of the doctrine of general revelation. The catastrophic effects that Penner perceives turn out to be only against a straw man (...) of the version of natural theology that I defend. (shrink)

When pressed, many atheists offer three reasons why they reject theism: there is strong evidence against theism, there is no strong evidence for theism, and theism is so outrageous that it needs a great deal of support in order for us to believe it in a reasonable manner. I examine the third reason, arguing that it fails.

William Lane Craig has defended the following two contentions: (1) If theism is true, we have a sound foundation for morality, and, (2) If theism is false, we do not have a sound foundation for morality. Erik Wielenberg rejects (2). Specifically, Wielenberg argues that naturalists have resources to make sense of objective moral values, moral duties, and moral knowledge. In response to Wielenberg, I defend Craig’s second contention by arguing that Wielenberg’s theory fails to robustly capture our moral phenomenology as (...) well as make intelligible robust moral knowledge.

Some philosophers and scientists argue that as science progresses the religious domain shrinks ever more. They see the advance of science as an argument against religion and for naturalism. In what follows I construct the argument that is tacit in this line of reasoning and criticize it.

This essay assesses Paul Draper's argument from evolution to atheism.

This paper outlines an argument for atheism from naturalism that I have developed in more detail elsewhere (in particular, in *The Best Argument against God*). The overall shape of the argument is as follows: first, naturalism is simpler than theism; second, there is no data that naturalism does not explain at least as well as theism; and, third, naturalism entails atheism; so we have good reason to prefer atheism to theism. Note that this statement of the shape of the argument (...) is NOT a statement of the argument itself. (shrink)

I develop two problems, which I call the problem of divine location and the problem of divine age, to challenge the theist belief that God created the universe. The problem of divine location holds that it is not clear where God existed before he created the universe. The problem of divine age holds that it is not clear how old God was when he created the universe. I explore several theist responses to these two problems, and argue that all of (...) them are problematic under the existing conceptions of space and time in physics. The philosophical magnitudes of these two problems are equal to that of the problem of evil. (shrink)

The challenge from religious diversity is widely thought to be one of the most important challenges facing religious belief. Despite this consensus, however, many epistemologists think that standard versions of the challenge fail because they threaten to implicate many seemingly reasonable yet highly controversial non-religious beliefs. In light of this we develop an alternative, less discussed, diversity challenge that does not generalize. This challenge concerns why so much religious diversity exists in the first place given common religious, and in particular (...) theistic, views. Although there are some interesting scientific explanations of such diversity, satisfying theistic explanations of its existence are still required. (shrink)

This article discusses “explaining away” arguments in the cognitive science of religion. I distinguish two rather different ways of explaining away religion, one where religion is shown to be incompatible with scientific findings and one where supernatural entities are rendered superfluous by scientific explanations. After discussing possible objections to both varieties, I argue that the latter way offers better prospects for successfully explaining away religion but that some caveats must be made. In a second step, I spell out how CSR (...) can be used to spell out an argument of the second kind. One argument renders religion superfluous by claiming that it results from a cognitive bias and one does the same by claiming religion was a useful evolutionary adaptation. I discuss some strengths and weaknesses of both arguments. (shrink)

In this article, we examine in detail the New Atheists' most serious argument for the conclusion that God does not exist, namely, Richard Dawkins's Ultimate 747 Gambit. Dawkins relies upon a strong explanatory principle involving simplicity. We systematically inspect the various kinds of simplicity that Dawkins may invoke. Finding his crucial premises false on any common conception of simplicity, we conclude that Dawkins has not given good reason to think God does not exist.

Pope Francis takes the Big Bang as supplying empirical evidence for God’s existence, going so far as to credit God’s will as the force behind natural selection. So if natural selection is the emanation of divine will, then so too is what Richard Dawkins calls the “selfish gene” underlying it. The trouble is that the natural forces of self-interest may win out over the better angels of our nature, spelling disaster for the human species—and the planet sustaining it. For the (...) drive of individual self-interest is the main fuel of capitalism, which has become the dominant global economic paradigm. And this unbridled self-interest is arguably most responsible for widespread environmental degradation. Therefore, if humanity should ultimately expire as a direct result of its evolutionary adaptations, it won’t exactly be a ringing endorsement of the architect of life, the universe, and everything.

This article examines philosophical naturalism—the chief rival to theism in the modern world— with contemporary apologetic concerns in view. The second section introduces the central claims of naturalism and the main arguments offered on its behalf. The third section surveys the challenges naturalism faces in accounting for two key features of human nature. The final section outlines the significance of these challenges in the context of an inference to the best explanation for theism.

In this paper, I argue that there is a kind of evil, namely, the unequal distribution of natural endowments, or natural inequality, which presents theists with a new evidential problem of evil. The problem of natural inequality is a new evidential problem of evil not only because, to the best of my knowledge, it has not yet been discussed in the literature, but also because available theodicies, such the free will defense and the soul-making defense, are not adequate responses in (...) the face of this particular evil, or so I argue.

This paper consider three families of arguments for atheism. First, there are direct arguments for atheism: arguments that theism is meaningless, or incoherent, or logically inconsistent, or impossible, or inconsistent with known fact, of improbable given known fact, or morally repugnant, or the like. Second, there are indirect arguments for atheism: direct arguments for something that entails atheism. Third, there are comparative arguments for atheism: e.g., arguments for the view that (atheistic) naturalism is more theoretically virtuous than theism.

This paper argues that considerations about causal origins of the universe do not favour theism over naturalism. Indeed, if the only data that is relevant to the choice between theism and naturalism is data about causal origins, then it turns out that considerations about causal origins favour naturalism over theism.

David Hume’s views on the subject of free will are among the most influential contributions to this long-disputed topic. Throughout the twentieth century, and into this century, Hume has been widely regarded as having presented the classic defense of the compatibilist position, the view that freedom and responsibility are consistent with determinism. Most of Hume’s core arguments on this issue are found in the sections entitled “Of liberty and necessity,” first presented in Book 2 of A Treatise of Human Nature (...) (1739) and then in his An Enquiry concerning Human Understanding (1748). Although the general position in both these works is much the same, there are some significant points of difference relating to the way in which the core position is presented and also in the specific range of arguments covered. The focus of my concerns in this essay will not, however, lie with the relationship between the Treatise and the first Enquiry versions of “Of liberty and necessity.” My discussion will center on the contrast between two alternative interpretations of Hume’s views on this subject, with particular reference to the version presented in the Treatise. It will be my particular concern to explain and defend the naturalistic as against the classical compatibilist account and to explain the general significance of the naturalistic account for the contemporary debate.
