Ontological Arguments for Theism

-/- The term “natural religion” is sometimes taken to refer to a pantheistic doctrine according to which nature itself is divine. “Natural theology”, by contrast, originally referred to (and still sometimes refers to)[1] the project of arguing for the existence of God on the basis of observed natural facts. -/- In contemporary philosophy, however, both “natural religion” and “natural theology” typically refer to the project of using all of the cognitive faculties that are “natural” to human beings—reason, sense-perception, introspection—to investigate (...) religious or theological matters. Natural religion or theology, on the present understanding, is not limited to empirical inquiry into nature, and it is not wedded to a pantheistic result. It does, however, avoid appeals to special non-natural faculties (ESP, telepathy, mystical experience) or supernatural sources of information (sacred texts, revealed theology, creedal authorities, direct supernatural communication). In general, natural religion or theology (hereafter “natural theology”) aims to adhere to the same standards of rational investigation as other philosophical and scientific enterprises, and is subject to the same methods of evaluation and critique. Natural theology is typically contrasted with “revealed theology”, where the latter explicitly appeals to special revelations such as miracles, scriptures, and divinely-superintended commentaries and creedal formulations. (See DeCruz and DeSmedt 2015) -/- Philosophers and religious thinkers across almost every epoch and tradition (Near Eastern, African, Asian, and European) have engaged the project of natural theology, either as proponents or critics. The question of whether natural theology is a viable project is at the root of some of the deepest religious divisions: Shi’ite thinkers are optimistic about reason’s ability to prove various theological and ethical truths, for instance, while Sunnis are not; Roman Catholic theologians typically think that reason provides demonstrations of the existence of God, while many Protestant theologians do not. Unlike most of the topics discussed in an encyclopedia of philosophy, this is one over which wars have been fought and throats have been cut. -/- The most active discussions of natural theology in the West occurred during the high medieval period (roughly 1100–1400 C.E.) and the early modern period (1600–1800 C.E.). The past few decades have witnessed a revival of natural theological debate in the public sphere: there are now institutes promoting “Intelligent Design Theory”, popular apologetics courses, campus debates between believers and agnostics, a “New Atheist” movement, Youtube debates between apologists and atheists regarding new books in natural theology (such as the one between Nathan Lewis and Bernie Dehler on the Blackwell Companion to Natural Theology),[2] and TED talks by famous atheists on how to resist natural religion (such as the one by Richard Dawkins in February 2002).[3] -/- Among professional philosophers (who aren’t typically part of these more popular debates), arguments over our ability to justify positive or negative answers to religious questions have become fairly technical, often employing sophisticated logical techniques in an effort to advance the discussion instead of retreading the same old ground. The prestigious Gifford Lectures series hosted by a consortium of Scottish universities, however, has tried to feature new but still accessible work in natural theology for over 100 years (it too has a Youtube channel!)[4] -/- In this article, we aim to avoid most the more recent complexities but also explain their origins by focusing on some central developments in the early modern period that helped to frame contemporary natural theological debates. We are focused here only on theoretical arguments (both a priori and a posteriori or empirical ones). It is controversial whether moral arguments are also part of natural theology, but we set them aside here (see also the entry on God, arguments for the existence of: moral arguments). (shrink)

I set out and explore an argument for God's existence based on the idea that the possibility of God requires the existence of God as a ground. After setting this argument out, I compare it to other arguments for God, concentrating on an argument from Descartes's Third Meditation. I then address various objections and conclude by setting out a non-theistic version of the argument.

This article aims to provide a new ontological argument for the existence of God. A specific ‘modal’ version of the ontological argument—termed the Modal Realist Ontological Argument—is formulated within the modal realist metaphysical framework of David K. Lewis, Kris McDaniel and Philip Bricker. Formulating this argument within this specific framework will enable the plausibility of its central premise (i.e., the ‘Possibility Premise’) to be established, and allow one to affirm the soundness of the argument—whilst warding off two oft-raised objections against (...) this type of natural theological argument. (shrink)

Some critics claim that ontological arguments are dialectically ineffective against sceptics, whatever the sceptics’ broader metaphysical commitments. In this paper, I examine and contest arguments for this conclusion. I suggest that such critics overlook important claims about God’s nature (viz. divine simplicity and divine inimitability) typically advanced by proponents of ontological arguments who endorse classical theism. I reformulate two representative ontological arguments in light of this characterization of God, arguing that for philosophers prepared to endorse Meinongianism or modal Platonism, alongside (...) divine simplicity and inimitability, such arguments are not invalid, question-begging, or obviously liable to parody. Accordingly, two species of ontological argument may possess some persuasive force, albeit for a select audience. (shrink)

Absolute nothing is the absence of our universe and its laws. Without these rules, nothingness has infinite potential. This implies that within the infinite probability of nothing, infinity can emerge. This would be expressed through infinite universes like our own. Infinite of these universes will differ by several particles, appearing and disappearing for no reason other than fulfilling every possibility. This universe is the product of a greater realisation of infinity and we can test this theory via the measurement of (...) our universe’s most fundamental particles appearing and disappearing for no discernible internal reason (random to our perspective).

An analysis of Scripture uncovers a new model of God’s election and predestination of souls, which fits under the umbrella of the Calvinist theologies, but where this model involves an answer to the long-standing question of why God chose some, rather than all. It will be explored how before souls were elected (or condemned), God looked at them and knew them in a pre-election state, which God used to predestine each soul in physical reality. This analysis reveals why it could (...) be no other way but where God only would choose some, rather than all souls during the physical embodiment stage of the soul, and the vexing centuries-old Calvinist question of why God elected some not all has an answer.

This paper argues that Spinoza held substances other than God to be inconceivable. It uses this claim to develop a novel response to the Problem of Other Substances, the problem of explaining why some of Spinoza’s proofs for God’s existence cannot be used to prove the existence of a non-divine substance instead.

Kant rejects the ontological argument on the grounds that the ontological argument inescapably must assume that existence is a “determination” or “real predicate,” which it is not. Most understand Kant’s argument for this claim to be premised upon his distinctive proto-Fregean theory of existence. But this leaves Kant dialectically vulnerable: the defender of the ontological argument can easily reject this as question-begging. I show that Kant relies upon two distinct arguments, both of which contend that the claim that existence is (...) a determination is inconsistent with bedrock ontological set pieces assumed by rationalist defenders of the ontological argument.

James Anderson and Greg Welty have resurrected an argument for God’s existence, which we will call the argument from logic. We present three lines of response against the argument, involving the notion of necessity involved, the notion of intentionality involved, and then we pose a dilemma for divine conceptualism. We conclude that the argument faces substantial problems.

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)

Variations on the ontological argument for most minimal and most mediocre beings.

Lewisian theism is the view that both traditional theism and Lewis’s modal realism are true. On Lewisian theism, God must exist in worlds in one of the following ways: God can be said to have a counterpart in each world; God can be said to exist in each world in the way that a universal can be said to exist in worlds, i.e. through transworld identity; God can be said to be a scattered individual, with a part of God existing (...) in each world; and, God can be said to exist in each world, through His existing from the standpoint of each world. In the literature, – have been rejected as viable options. I grant that and are not viable. However, I believe that and have been too hastily rejected. Herein, I develop ways to respond to objections to and, and conclude that is a viable option for Lewisian theists. (shrink)

God is omniscient; therefore, He knows that ‘the flower in my hand is red.’ If God knows that ‘the flower in my hand is red,’ then He knows it perceptually. God does not know anything perceptually. It is clear that the set of propositions – form an inconsistent triad. This is one of four problems with which Avicenna was engaged concerning God's knowledge of particulars, which I call the problem of perceptual knowledge. In order to solve PPK and three other (...) problems, Avicenna has developed a theory concerning God’s knowledge of particulars. Secondary literature around Avicenna’s theory of God’s knowledge of particulars has mostly directed its attention to give an account of Avicenna’s positive theory rather than the problems which that theory was designed to solve. But this paper will not do the same thing as this secondary literature. In contrast, in this paper, I will concentrate on the characterization of one of the problems, i.e., PPK, because of which Avicenna has presented his positive theory of God’s knowledge of particulars. In short, this paper aims to show why Avicenna deems explaining God’s knowledge of, say, the redness of a flower, via his accepted theory of perception as problematic. In this regard, I will extract three versions of PPK based on Avicenna's philosophy and through it will shed some light on Avicenna’s theory of God’s knowledge of particulars. (shrink)

In Tobia (2016), Kevin P. Tobia tests for bias using two ontological arguments claimed to be symmetrical and of equal strength. We show they are neither.

Meu objetivo neste texto é apresentar uma resposta cética ao argumento ontológico tal como aparece em algumas de suas principais variações. O que todas essas variações têm em comum é tentar provar a existência de Deus a priori. Sustentarei que o sucesso de qualquer argumento desse tipo depende de dois pressupostos fundamentais, o primeiro é que existência é uma propriedade e o segundo que é uma perfeição. Mesmo aceitando que existência seja uma propriedade, recusarei que possamos saber se ela é (...) uma perfeição e, portanto, que possamos saber se devemos atribuí-la a um ser perfeito. Serão trabalhadas quatro formulações diferentes desse argumento, começando por Anselmo, Descartes, e a formulação que Norman Malcom acredita haver em Anselmo. Por fim, considerarei a versão de Alvin Plantinga, que defende o argumento ontológico sem sustentar que existência é uma perfeição. Sustentarei que seu argumento falha em provar que Deus existe, pois é inválido. (shrink)

Is theistic evolution (TE) a philosophically tenable position? Leidenhag argues in his article “The Blurred Line between Theistic Evolution and Intelligent Design” that it is not, since it, Leidenhag claims, espouses a view of divine action that he labels “natural divine causation” (NDC), which makes God explanatory redundant. That is, in so far as TE does not invoke God as an additional cause alongside natural causes, it is untenable. Theistic evolutionists should therefore “reject NDC and affirm a more robust notion (...) of divine agency.” However, this will, Leidenhag claims, have the effect that theistic evolutionists “will move their position significantly closer to Intelligent Design,” and so the line between TE and intelligent design is (or ought to be?) blurred. If successful, the criticism by Leidenhag would be bad news for theists who want to take science seriously and good news for those scientistic atheists according to whom there simply is no scientifically respectable way of combining theism and modern natural science in an overarching worldview. So, is TE stuck between a rock (of redundancy) and a hard place (of pseudo‐science)? No, at least not due to the criticism offered by Leidenhag—but maybe religious naturalism is? (shrink)

Q: Is Thomas Aquinas's account of creation compatible with the account of the natural world given by the contemporary empirical sciences?

Many Christian scholars have argued that standard versions of evolutionary theory and orthodox theological commitments can be reconciled. Some theistic evolutionists or “evolutionary creationists” have argued that evolutionary mechanisms such as random mutation and natural selection are nothing less than God’s way of creating. Though I dispute the logical coherence of these attempted reconciliations elsewhere, I argue here that there is little reason for Christians to attempt them, since an accumulating body of evidence from multiple subdisciplines of biology casts doubt (...) on the creative power of the main evolutionary mechanisms. Thus, rather than addressing the question, “Can a meaningful doctrine of divine providence or creation be reconciled with mainstream evolutionary theory?” this essay will address the question of whether Christians should, or need to, attempt such a reconciliation at all.

Here I consider the two most venerated arguments about the existence of God: the Ontological Argument and the Argument from Evil. The Ontological Argument purports to show that God’s nature guarantees that God exists. The Argument from Evil purports to show that God’s nature, combined with some plausible facts about the way the world is, guarantees (or is very compelling grounds for thinking) that God does not exist. Obviously, both arguments cannot be sound. But I argue here that they are (...) both unsound for the very same reason. (shrink)

This article explores Karl Rahner’s conception of the “Liturgy of the World” in light of the theme for the 2019 Annual Convention of the Catholic Theological Society of America, “Another World is Possible: Violence, Resistance and Transformation.” Employing Rahner’s hermeneutics of worship, violence can be conceived as a denial of this cosmic liturgy, transformation as conversion to it, and resistance as the stance opposing the denial. Resistance entails solidarity with all humanity in liturgical participation and in action for social justice. (...) Metz’s political-theological critique of Rahner, with assistance from Bruce Morrill’s analysis of Metz’s work for liturgical theology, and Rahner’s reference to Teilhard’s “Cosmic Mass,” taken today in light of contemporary cosmology with assistance from Roger Haight’s non-dualistic approach to models of God, are among the implications to be considered for engaging Rahner’s vision in ongoing efforts at liturgical renewal. (shrink)

I argue that John Hick’s soul-making theodicy is committed to opposing social progress. By focusing on justifying the current amount and distribution of suffering and evil, Hick’s theodicy ends up having to condemn even positive change as undesirable. First, I give a brief outline of Hick’s theodicy, with a particular emphasis on the role of earned virtue in justifying the existence of evil. Then I consider two understandings of social progress: progress as the elimination of suffering and evil; and progress (...) as the promotion of earned virtue. I further distinguish the earned virtue understanding of social progress into two kinds, in which the relationship between social structures and moral growth either: allows members of a more advanced society to start closer to perfection; or allows members of a more advanced society to progress more quickly. I argue that no matter which approach we take, Hick’s theodicy struggles with the idea of social progress. Hick is either straightforwardly committed to opposing social progress, or he can support it only at the expense of being unable to justify status quo of suffering and evil. (shrink)

Some Molinists claim that a perfectly good God would actualize a world that is salvifically optimal, that is, a world in which the balance between the saved and damned is optimal and cannot be improved upon without undesirable consequences. I argue that given some plausible principles of rationality, alongside the assumptions Molinists already accept, God’s perfect rationality necessarily would lead him to actualize a salvifically optimal world; I call this position “Optimistic Molinism.” I then consider objections and offer replies, concluding (...) that Optimistic Molinism is undefeated and merits further exploration.

This paper examines the coherence of naturalistic personal pantheism in an attempt to reconcile pantheism, naturalism, and a personal concept of God. NPP proposes that i) God is identical with the universe, ii) the universe is entirely natural, and iii) God is personal. Several critics of accounts of a God such as this have voiced concerns about a natural — as opposed to a supernatural — God, since a natural God cannot be worship-worthy. In response, I propose a controversial premise (...) — physical primacy — to justify the worship-worthiness of a natural God. Physical primacy maintains that physical existence is a great-making property, therefore a God that exists naturally is greater than a God that exists supernaturally. I maintain that NPP is an attractive alternative to other theisms because it bypasses the pairing problem, presents a worship-worthy concept of God, and boasts ontological simplicity. (shrink)

Criticizing Richard Swinburne’s conception of God, John Hick argues that God cannot be personal because infinity and personhood are mutually incompatible. An essential characteristic of a person, Hick claims, is having a boundary which distinguishes that person from other persons. But having a boundary is incompatible with being infinite. Infinite beings are unbounded. Hence God cannot be thought of as an infinite person. In this paper, I argue that the Hickian argument is flawed because boundedness is an equivocal notion: in (...) one sense it is not essential to personhood, and in another sense—which is essential to personhood—it is compatible with being infinite. (shrink)

The question whether God should be thought of as personal or a-personal is closely linked to the issue of an appropriate model of God-world relation on the one hand and the question how to conceive divine action on the other hand. Starting with a discussion of the scientific character of theology, this article critically examines the univocal-personal concept of God. Traditional Christian conceptions of God have, however, always acknowledged a radical asymmetry between the personal existence of created beings and the (...) ground of being itself. In a second step, the ontological truth claim associated with this way of speaking about God is being related to its methodological consequences. In final step, attention is given to the relation of immanence and transcendence as it is defended in different versions of panentheism: As an alternative to divine interventionism, panentheism can be shown to explicate divine providence as formal and final causation.

Robert Cummings Neville1 first came to my attention when I was a senior in college. "Ah, but I was so much older then, I'm younger than that now," as Bob Dylan crooned at the time. Serious and studious, I was reading scholarly journals in the stacks one Saturday night. Among them was the journal Theological Studies, and in the March 1969 issue was the most effusive book review I had ever read. It was of Neville's very first book, God the (...) Creator: On the Transcendence and Presence of God. The Dominican reviewer was suitably impressed by the "brilliant" argument, but more than that, he was astonished to think that "Neville, at the time of publication, was twenty-eight."2 Curious about a brilliant author who was still...

Absorbing—being absorbed in—the vision of Robert Neville's Philosophical Theology recalled to me a lowly cartoon by much-beloved Australian cartoonist Michael Leunig.1 A small man carries a big briefcase on a smudgy street. With a look of—relief? regret? foreboding? anticipation?—the man beholds a sign on a wall that reads: "If you see anything mysterious or unusual just enjoy it while you can." Neville's vision is unusual, and the contemplation of mystery sounds as a basso continuo through each and all three opera (...) of his Philosophical Theology. I want to say: enjoy it while you can. For who can say whether its beauty is that of things ephemeral or something more perennial?It seems we might be coming to an end of... (shrink)

Both individually and collectively, the five essays in this groups are brilliant. Each of the authors has worked with extraordinary care and success to represent my position, and they all succeed.

David Rohr's explores in depth my epistemology and shows its relevance to my philosophy as a whole and also to its application (...) to Christian sermons.

During a time period spanning from 2013 to 2015, Robert Neville published the three volumes of his magnum opus on Philosophical Theology, selected aspects of which will be the main focus of my attention in this essay.1 Rather than hover at ten thousand feet and try to provide a broad overview or a bare sketch of Neville's thought as he developed it there, I have decided to take the plunge, to focus my attention more narrowly on specific issues, while trying (...) also to illuminate as much of the rest of his philosophical theology as I possibly can. This means lingering over volume one of his trilogy, on Ultimates, to a greater extent than I do with either volume two, on Existence, or volume three, on Religion.2 Within... (shrink)

C. S. Peirce claimed that the pragmatic method of clarifying ideas is "nothing but a particular application of an older logical rule, 'By their fruits ye shall know them.'"1 While Jesus spoke about discriminating between true and false religious teachers, Peirce was concerned with clarifying our intellectual concepts. Peirce's pragmatism asserts that we clearly understand the meaning of a concept if we can state the potentially practical and empirical consequences that would follow from the truth of a proposition involving that (...) concept. Robert C. Neville's semiotic and pragmatic theory of religious truth unites Jesus's and Peirce's concerns, proposing that religious truth consists in an adaptedness or fit between... (shrink)

Zusammenfassung Kurt Gödels Ontological Proof von 1970 ist einer der bedeutendsten Beweise der Existenz Gottes unserer Zeit. Die Formulierung in formaler Logik erschwert erstens das Verständnis und scheint zweitens einen unbedingten Wahrheitsbezug zu implizieren. Seit seiner Veröffentlichung bis heute wurde sich auf vielfältige Weise mit dem Beweis auseinandergesetzt und dazu publiziert. Allerdings fehlt bislang eine theologische – insbesondere eine protestantisch-theologische – Auseinandersetzung. Dieser Aufsatz soll eine systematische Übersicht über die bisherige Forschung sowie eine Einführung und Erläuterung des Beweises geben. Der (...) theologische Forschungsbeitrag besteht hierbei vor allem in einer Relativierung einiger mit dem Beweis und seiner Rezeption verbundenen Ansprüche. (shrink)

In this article, we deal with the intelligible world of the angels in the Areopagetic tradition and we compose references found in the De divinis nominibus to form, as far as possible, a complete definition of them. This systematic approach to the Areopagetic corpus takes into consideration Pseudo-Dionysius the Areopagite’s text and George Pachymeres’ Paraphrasis of this treatise. We also offer a methodological proposal on how we can structure theoretically general concepts that refer to objective realities, which however cannot be (...) proved by the tools of formal Logic.

This paper explores a variety of perfect being theism that combines Yujin Nagasawa’s maximal God thesis with the view that God is not atemporal. We argue that the original maximal God thesis still implicitly relies on a “static” view of divine perfections. Instead, following the recent re-evaluation of divine immutability by analytic philosophers, we propose that thinking of divine great-making properties as fluctuating but nevertheless remaining maximal either for every time t or across all times strengthens the original maximal God (...) thesis. Furthermore, we show that “temporalising” Nagasawa’s maximal God and adopting what we call the fluctuating maximal God thesis provides more effective ways of responding to objections to perfect being theism, in particular, the argument from evil and some conceptual problems pertaining to the Incarnation. Finally, we demonstrate that our proposal is compatible with Christian Scriptures and coheres with numerous biblical passages better than Nagasawa’s original proposal does. (shrink)

Panentheism, a frequently discussed view in recent theological debate, claims that the world is ‘in God’ but that God is ‘more than’ the world. Different theories of the structure of the world produce distinct panentheist views. According to the hunky structure, the world is composed of an infinite number of layers and lacks an ungrounded level. To depict this model, I employ the concepts of ‘grounding’ and ‘emergence.’ The outcome is that if the world is hunky and material reality emerges (...) from such a structure, the world can be in God, but the model of God the Creator is dismissed.

I interpret Adorno's bold claim that all philosophy revolves around the ontological argument. On my reading, Adorno thereby expresses that all philosophy revolves around the question whether all of reality can be captured by thought. I then interpret the significance of this thesis for Adorno's *Negative Dialectics*. I argue that Adorno does not give up the ontological argument's claim—capturing reality in thought—but gives it a Marxist spin: whether reality can be captured in thought depends on its historical development, and is (...) therefore also up to humans and their actions.

It is a commonly held view that the existence of moral value somehow depends upon the existence of God. Some proponents of this view take the very strong position that atheism entails that there is no moral value; but most take the weaker position that atheism cannot explain what moral value is, or how it could have come into being. Call the first position Incompatibility, and the second position Inadequacy. In this paper, I will focus on the arguments for Inadequacy. (...) There are two main arguments for this position: the Argument from Arbitrariness and the Screening-Off Argument. I’ll discuss each in turn., and argue that neither is successful. To conclude, I’ll sketch what I think is a promising beginning to a naturalistic account of morality. (shrink)
