Arguments from Naturalism against Theism

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.

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

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)

In the Natural history of religion, Hume attempts to understand the origin of our folk belief in gods and spirits. These investigations are not, however, purely descriptive. Hume demonstrates that ontological commitment to supernatural agents depends on motivated reasoning and illusions of control. These beliefs cannot, then, be reflectively endorsed. This proposal must be taken seriously because it receives support from recent work on our psychological responses to uncertainty. It also compares quite favorably with its main competitors in the cognitive (...) science of religion. (shrink)

J. L. Schellenberg claims that the weakness of evidence for God’s existence is not merely a sign that God is hidden, “it is a revelation that God does not exist.” In Divine Hiddenness: New Essays, Michael J. Murray provides a “soul-making” defense of God’s hiddenness, arguing that if God were not hidden, then some of us would lose what many theists deem a (very) good thing: the ability to develop morally significant characters. In this paper, I argue that Murray’s soul-making (...) defense not only fails to defend God’s hiddenness, it produces (ironically) an argument for the nonexistence of God. (shrink)

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)

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.

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)

Review of Craig And Mroeland: *Naturalism: A Critical Analysis*.

In this 2007 volume, eighteen of the world's leading scholars present original essays on various aspects of atheism: its history, both ancient and modern, defense and implications. The topic is examined in terms of its implications for a wide range of disciplines including philosophy, religion, feminism, postmodernism, sociology and psychology. In its defense, both classical and contemporary theistic arguments are criticized, and, the argument from evil, and impossibility arguments, along with a non religious basis for morality are defended. These essays (...) give a broad understanding of atheism and a lucid introduction to this controversial topic. (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)

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)

In this paper, I argue that -- contrary to widely received opinion -- logical arguments from evil are well and truly alive and kicking.

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.

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.

I prove the nonexistence of gods. The proof is based on three axioms: Ockham’s razor (OR), religiosity is endogenous in humans, and, there are no miracles. The OR is formulated operationally, to remove improper postulates, such that it yields not only a plausible argument but truth. The validity of the second and the third axiom is established empirically by inductive reasoning relying on a thorough analysis of the psychiatric literature and skeptical publications. With these axioms I prove that gods are (...) not necessary for our universe. Applying OR yields that gods do not exist. The implications of this article are enormous. Mankind’s understanding of the world is elevated to a higher level to a unified view on the world being nature and mankind being a part of it. (shrink)

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

Some people feel threatened by the thought that life might have arisen by chance. What is it about “chance” that some people find so threatening? If life originated by chance, this suggests that life was unintended and that it was not inevitable. It is ironic that people care about whether life in general was intended, but may not have ever wondered whether their own existence was intended by their parents. If it does not matter to us whether one's own existence (...) was intended, as will be hypothesized, then why should it matter whether there was some remote intent behind the creation of the first unicellular organism(s) billions of years ago? I will discuss three possible scenarios by which life might have originated. I will then argue that, in regard to whether one’s individual life can be meaningful, it does not matter whether life was intended or arose by chance. If complex life was unintended and is rare in this universe, this is not a reason to disparage life, but a reason to appreciate and value our existence. -/- . (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.

Some argue for materialism claiming that a physical event cannot have a non-physical cause, or by claiming the 'Principle of Causal Closure' to be true. This I call a 'Sweeping Naturalistic Argument'. This article argues against this. It describes what it would be for a material event to have an immaterial cause.

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.

This paper rejects a view of science called "methodological naturalism." -/- According to many defenders of mainstream science and Darwinian evolution, anti-evolution critics--creationists and intelligent design proponents--are conceptually and epistemologically confusing science and religion, a supernatural view of world. These defenders of evolution contend that doing science requires adhering to a methodology that is strictly and essentially naturalistic: science is essentially committed to "methodological naturalism" and assumes that all the phenomena it investigates are entirely natural and consistent with the laws (...) of physics. Thus encountering any unexplained phenomenon, science assumes a priori that there is some natural cause and will only test a natural hypothesis. Since by definition supernatural causes are assumed to be not subject to the constraints of physical or natural law as understood by science, supernatural hypotheses and explanations must be banned from proper science. Science simply can't say that God did, or did not do it. -/- I argue that the success of science is directly relevant to rational belief in supernatural causes, and that in fact science can and does say in particular cases that "God didn't do it." I suggest that pro-evolution proponents can better defend science and the theory of evolution by rejecting methodological naturalism. -/- . (shrink)

A number of recent historians claim to have defeated what they call the ‘conflict thesis’, the idea that there exists some inevitable conflict between Darwinism and Christianity. This is often thought to be part of a broader ‘warfare thesis’, which posits an inevitable conflict between science and religion. But, all they have defeated is one, relatively uninteresting form of this thesis. There remain other forms of the conflict theses that remain entirely plausible, even in light of the historical record.

This is an unpublished talk written for a meeting of French philosophers. The paper describes the evolution versus creationism/intelligent design controversy in the U.S. A number of philosophers and scientists try to resolve this issue by sharply distinguishing the realm of science versus any talk of the supernatural. These pro-evolutionists often appeal to science's essential commitment to "methodological naturalism," the view that scientific methodology is essentially committed to naturalism and cannot meaningfully entertain hypotheses concerning the supernatural. I criticize methodological naturalism, (...) suggesting that such an appeal is misguided and counterproductive. I suggest an alternative view of the supernatural consistent with scientific knowledge.

Quentin Smith argues that if God exists, He had a duty to ensure life's existence; and He couldn't rationally have done so and made a big bang unless a counter-factual like "If God had made a big bang, there would have been life," was true pre-creation. But such counter-factuals are not true pre-creation. I argue that God could have made a big bang without irrationality; and that He could have ensured life without making big bangs non-random. Further, a proper understanding (...) of the truth-conditions of counter-factuals like the one above lets them have determinate truth-values pre-creation. But the explanation of how the above counter-factual can be true pre-creation is more complicated than that offered by William Lane Craig. (shrink)

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)

Where was God? Where was the intelligent designer of the universe when 1.5 million children were turned into smoke by zealous Nazis? Where was the all powerful, all knowing, wholly good being whose very essence is radically opposed to evil, while millions of children were starved to death by Stalin, had their limbs chopped off with machetes in Rwanda, were turned into amputees by the diamond trade in Sierra Leone, and worked to death, even now, by the child slave trade (...) that, by conservative estimates, enslaves 250 million children worldwide?Without divine justice, all of this suffering is gratuitous. How, then, can a wholly good, all-powerful God be believed to exist? The existence of evil is the most fundamental threat to the traditional Western concept of an all-good, all-powerful God. Both natural evil, the suffering that occurs as a result of physical phenomena, and moral evil, the suffering resulting from human action, comprise the problem of evil. If evil cannot be accounted for, then belief in the traditional Western concept of God is absurd. (shrink)
