In this paper, I propose that, in addition to the multiverse hypothesis, which is commonly taken to be an alternative explanation for fine-tuning, other than the design hypothesis, the simulation hypothesis is another explanation for fine-tuning. I then argue that the simulation hypothesis undercuts the alleged evidential connection between ‘designer’ and ‘supernatural designer of immense power and knowledge’ in much the same way that the multiverse hypothesis undercuts the alleged evidential connection between ‘fine-tuning’ and (...) ‘fine-tuner’ (or ‘designer’). If this is correct, then the fine-tuning argument is a weak argument for the existence of God. (shrink)

According to the Fine-Tuning Argument, the existence of life in our universe confirms the Multiverse Hypothesis. A standard objection to FTA is that it violates the Requirement of Total Evidence. I argue that RTE should be rejected in favor of the Predesignation Requirement, according to which, in assessing the outcome of a probabilistic process, we should only use evidence characterizable in a manner available before observing the outcome. This produces the right verdicts in some simple cases in (...) which RTE leads us astray, and, when applied to FTA, it shows that our evidence does confirm HM. (shrink)

It is commonly argued that the fact that our universe is fine-tuned for life favors both a design hypothesis as well as a non-teleological multiverse hypothesis. The claim that the fine-tuning of this universe supports a non-teleological multiverse hypothesis has been forcefully challenged however by Ian Hacking and Roger White. In this paper we take this challenge even further by arguing that if it succeeds, then not only does the fine-tuning of this universe fail to (...) support a multiverse hypothesis, but it tends to favor a single-universe hypothesis instead. (shrink)

A version of the Fine-tuning Argument (FTA) considered in a previous essay is replaced by an improved version, which is then refuted.Advocates of FTA must proclaim that there is no world ensemble, that a great many alternatives to the physical constants of our universe are physically possible and roughly equal in probability to them, and that alternate hypothetical worlds are all, or almost all, uninteresting in comparison to our universe. But no reason has been produced to believe (...) any of these claims, and so FTA, even in its improved version, can still be dismissed as unsupported, doubtful, and weak. (shrink)

A new formulation of the Fine-Tuning Argument (FTA) for the existence of God is offered, which avoids a number of commonly raised objections. I argue that we can and should focus on the fundamental constants and initial conditions of the universe, and show how physics itself provides the probabilities that are needed by the argument. I explain how this formulation avoids a number of common objections, specifically the possibility of deeper physical laws, the multiverse, normalisability, whether (...) God would fine-tune at all, whether the universe is too fine-tuned, and whether the likelihood of God creating a life-permitting universe is inscrutable. (shrink)

There are at least two kinds of design arguments for theism: fine-tuning arguments and biological design arguments. Dougherty and Poston (2008) have argued that the success of one requires the failure of the other, and vice versa. The reason is that the success of these arguments hinges on the following crucial probability: the probability that biological life exists somewhere in the universe given that (a) our universe is finely tuned and that (b) biological development is unguided by intelligence. (...) According to Dougherty and Poston, fine-tuning arguments require that the crucial probability is high while biological design arguments require that the crucial probability is low. As a result, at most one of these design arguments can factor into a cumulative case argument for theism. I argue that this is mistaken. Specifically, I show that fine-tuning arguments can succeed even if the crucial probability is low. (shrink)

This paper offers a defence of metaphysical naturalism, in the context of the Fine Tuning argument. Theistic objections to the Multiverse (MV) hypothesis are considered, specifically the claim that the MV hypothesis commits the Inverse Gambler’s Fallacy (IGF) and, as per the This Universe Objection (TUO), that it violates the Requirement of Total Evidence. It is argued that the IGF claim moved the goalposts when it comes to assessing the validity of the MV hypothesis. The Cosmic Slot (...) Machine analogy will be used to demonstrate how the This Universe Objection (TUO), fails to adequately account for the anthropic principle (or selection effect) and how the MV hyptothesis does satisfy the Requirement for Total Evidence. -/- With respect to the Naturalistic Single Universe (NSU), the implications of the ex-nihilonihil- fit principle, for evaluating the epistemic probability of a Life Permitting Universe (LPU)under the NSU hypothesis, are considered. It is argued that the ex nihilo nihil fit principle entails that an LPU is not improbable under the NSU hypothesis. (shrink)

Our universe seems to be miraculously fine-tuned for life. Multiverse theories have been proposed as an explanation for this on the basis of probabilistic arguments, but various authors have objected that we should consider our total evidence that this universe in particular has life in our inference, which would block the argument. The debate thus crucially hinges on how Bayesian background and evidence are distinguished and on how indexical or demonstrative terms are analysed. The aim of this article (...) is to take a step back and examine these various aspects of Bayesian reasoning and how they affect the arguments. The upshot is that there are reasons to resist the fine-tuning argument for the multiverse, but the “this-universe-objection” is not one of them. (shrink)

Abstract: Proponents of the this-universe objection to fine-tuning arguments for a multiverse claim that while the multiverse hypothesis raises the probability that some universe is fine-tuned for life, it fails to raise the probability that this one is. Because that is so, they further argue, those who take the fine-tuning of this universe as evidence for the multiverse hypothesis are guilty of a probabilistic fallacy. I argue that a proper evaluation of the this-universe objection requires (...) the development of a general, formal framework for reasoning probabilistically with evidence statements expressed using indexical terms (such as the statement This universe is fine-tuned). I proceed to develop such a framework and then to apply it to the this-universe objection. While my primary aim is to defend the this-universe objection from recent rebuttals, a secondary aim is to exhibit the utility of the framework itself, which has the potential for wider application.

Perry Hendricks’ original impairment argument for the immorality of abortion is based on the impairment principle (TIP): if impairing an organism to some degree is immoral, then ceteris paribus, impairing it to a higher degree is also immoral. Since abortion impairs a fetus to a higher degree than fetal alcohol syndrome (FAS) and giving a fetus FAS is immoral, it follows that abortion is immoral. Critics have argued that the ceteris paribus is not met for FAS and abortion, and (...) so we proposed the Modified Impairment Principle (MIP) to avoid these difficulties. Dustin Crummett has responded, arguing that MIP is open to various counterexamples which show it to be false. He also shows that MIP can generate moral dilemmas. Here, we propose a modification to MIP that resolves the issues Crummett raises. Additionally, Alex Gillham has criticized our appropriation of Don Marquis’ ‘future like ours’ reasoning about the wrongness of impairment. We show that his objections have minimal implications for our argument. (shrink)

This paper seeks to explicate and analyze an alternative response to fine-tuning arguments from those that are typically given—namely, design or brute contingency. The response I explore is based on necessity, the necessitarian response. After showing how necessity blocks the argument, I explicate the reply I claim necessitarians can give and suggest how its three requirements can be met: firstly, that laws are metaphysically necessary; secondly, that constants are metaphysically necessary; and thirdly, that the fundamental properties that (...) determine the laws and constants are necessary. After discussing each in turn, I end the paper by assessing how the response fares when running the fine-tuning argument in two ways, as an inference to best explanation and as a Bayesian argument. (shrink)

After briefly outlining the fine-tuning argument (FTA), I explain how it relies crucially on the claim that it is not improbable that God would design a fine-tuned universe. Against this premise stands the divine psychology objection: the contention that the probability that God would design a fine-tuned universe is inscrutable. I explore three strategies for meeting this objection: (i) denying that the FTA requires any claims about divine psychology in the first place, (ii) defining the (...) motivation and intention to design a fine-tuned universe into the theistic hypothesis, and (iii) providing arguments that the relevant probability is not terribly low. While I reject the first two, I conclude, in line with the third, that considerations about life's objective value establish that it is not absurdly improbable that God would design a fine-tuned universe, whether one regards the FTA as an inference merely to a cosmic designer, or to theism proper. Accordingly, the divine psychology objection fails. (shrink)

We are each entitled to our own opinions, and it’s my opinion that, as of this writing, 8/19/2021, physicists are endlessly confused about both the anthropic argument and the fine-tuning argument. Here is my take on them. The Anthropic argument (which I think works) involves two, not one, data points. The fine-tuning argument fails because ever smaller changes could always be contemplated.

The Fine-Tuning Argument (FTA) is an argument put forward by proponents of theism, in which they attempt to make a case from Bayesian inference, that the [apparently] fine tuned constants of our universe is more likely given a theistic hypothesis, than a naturalistic one. Some naturalists argue that this is not the case given the Multiverse (MV) hypothesis (that our universe is one of a plurality in a broader multiverse). The MV hypothesis is rejected by (...) theists who argue it commits what Ian Hacking (1987) referred to as “the Inverse Gambler’s Fallacy”. In this paper I will attempt to demonstrate [what I perceive as] the errors in logic made by theists first in positing that a life-permitting universe (LPU) is improbable under the naturalistic-single-universe (NSU) hypothesis, and subsequently the errors in arguing that the MV hypothesis commits what Ian Hacking (1987) referred to as “the Inverse Gambler’s Fallacy”. First, I will attempt to demonstrate why an LPU is not improbable under the NSU. Second, I will attempt to demonstrate that if we ascribe a probability value to our LPU, we can directly infer either an MV or the existence of “Deeper Laws” (Barnes, 2020) from that probability value. (shrink)

The fundamental constants that are involved in the laws of physics which describe our universe are finely-tuned for life, in the sense that if some of the constants had slightly different values life could not exist. Some people hold that this provides evidence for the existence of God. I will present a probabilistic version of this fine-tuning argument which is stronger than all other versions in the literature. Nevertheless, I will show that one can have reasonable opinions (...) such that the fine-tuning argument doesn’t lead to an increase in one’s probability for the existence of God. (shrink)

Neil Sinhababu :89–98, 2017) has recently argued against the fine-tuning argument for God. They claim that the question of the universe’s fine-tuning ought not be ‘why is the universe so hospitable to life?’ but rather ‘why is the universe so hospitable to morally valuable minds?’ and that, moreover, the universe isn’t so hospitable. For it is metaphysically possible that psychophysical laws be substantially more permissive than they in fact are, allowing for the realisation of morally (...) valuable consciousness by exceptionally simple physical states and systems, rather than the complex states of brains. I reply that Sinhababu’s argument rests upon unsupported claims and that we have reason to doubt that an omnibenevolent God would make the psychophysical laws more permissive than they in fact are. (shrink)

I present a novel objection to fine-tuning arguments for God's existence. On any values of the physical constants, the psychophysical laws could be set to permit intelligent and happy beings, so the specific values of the physical constants in our world provide little evidence for God's existence. For example, even if the physical constants didn't allow carbon or any atoms larger than hydrogen, the psychophysical laws could be set so that charge is sufficient to realize romantic desire. Then (...) every hydrogen atom would be a proton and electron in love. (shrink)

Recent research in science indicates that we are living in a fine-tuned universe. Only a very small parameter space of universal fundamental constants in Physics is congenial for the existence of life. Moreover, recent studies in Biological evolution also reveal that fine-tuning did exist in the evolution. It seems that we are so lucky to exist as all universal fundamental constants and life-permitting factors really fall into such a very small life-allowing region. This problem is known as (...) the fine-tuning problem. Does this phenomenon need an explanation? Can the fine-tuning problem point to the existence of God? Modern Science invokes the idea of multiverse to address the fine-tuning problem. Some scientists suggest that each universe in a set of infinitely many universes contains a typical set of fundamental constants. We should not be surprised why our universe is fine-tuned because we would not exist if the constants are not the life-allowed values. Some suggest that the existence of God can explain this fine-tuning problem. The naturalistic multiverse theory and the existence of God are the two most robust proposals to address the fine-tuning problem. Moreover, some argue that the fine-tuning problem is not real because we are just subject to observational selection effect. In this thesis, I will provide a comprehensive discussion on the fine-tuning phenomena in our universe. In particular, I will use the confirmation principle and the inference to the best explanation simultaneously to evaluate different hypotheses in a more systematic way and give some of the new and updated scientific and philosophical arguments to respond to the recent criticisms of the fine-tuning arguments. I conclude that the theistic hypothesis is the best among all to address the fine-tuning problem. (shrink)

This paper defends a novel sceptical response to the fine-tuning argument for the existence of God (FTA). According to this response, even if FTA can establish, what I call, the confirmation proposition: ‘fine-tuning confirms the God hypothesis’, there is no reason to think that a strengthening of FTA can establish the evidence-favouring proposition: ‘fine-tuning favours the God hypothesis over its competitors’. My argument is that, any criteria for the explanation of fine- (...) class='Hi'>tuning that permit us to take the God hypothesis seriously ought to make us sceptical that fine-tuning favours the God hypothesis over its competitors. As taking the God hypothesis seriously requires us to give a fair hearing to all sorts of non-theistic explanations, including the so-called weird sorts of atheism. (shrink)

Recent existential-risk thinkers have noted that the analysis of the fine-tuning argument for God’s existence, and the analysis of certain forms of existential risk, employ similar types of reasoning. This paper argues that insofar as the “many worlds objection” undermines the inference to God’s existence from universal fine-tuning, then a similar many worlds objection undermines the inference that the historic risk of global nuclear catastrophe has been low from the lack of such a catastrophe has (...) occurred in our world. A version of the fine-tuning argument applied to nuclear risk, The Nuclear Fine-Tuning Argument, utilizes the set of nuclear close calls to show that 1) conventional explanations fail to adequately explain how we have survived thus far and 2) the existence of many worlds provides an adequate explanation. This is because, if there are many worlds, observers are disproportionately more likely to reflect upon a world that hasn’t had a global nuclear catastrophe than upon one that has had a global nuclear catastrophe. This selection bias results from the catastrophic nature of such an event. This argument extends generally to all global catastrophic risks that both A) have been historic threats and B) would result in a significantly lower global population. (shrink)

Jonathan Weisberg (2010 ) argues that, given that life exists, the fact that the universe is fine-tuned for life does not confirm the design hypothesis. And if the fact that life exists confirms the design hypothesis, fine-tuning is irrelevant. So either way, fine-tuning has nothing to do with it. I will defend a design argument that survives Weisberg’s critique — the fact that life exists supports the design hypothesis, but it only does so given (...) fine-tuning. (shrink)

We can ask, (1) given the state of the universe at the big bang, what is the probability that the universe would have ended up in its current actual state? What is the probability distribution for the possible states the universe could have evolved into? We can ask, (2) given the current actual state of the universe, what is the probability the big bang would have been in the state it was? What is the probability distribution over different possible states (...) at the big bang? Both the Fine-Tuning argument and the Anthropic argument are confused versions of (2). This settles the issues once and for all. (shrink)

This paper will attempt to offer a defence of to the Multiverse (MV) hypotheses, in the context of the theistic Fine Tuning Argument (FTA). It will be argued that theistic proponents of the FTA who argue that the MV hypothesis commits the Inverse Gambler’s Fallacy (IGF) are, themselves, guilty of moving the goalposts when it comes to assessing the validity of the MV hypothesis. The Cosmic Slot Machine analogy will be used to demonstrate how the This Universe (...) Objection (TUO), first outlined by White (2000) and further clarified by Draper et al (2007), fails to adequately account for the anthropic principle (or selection effect). (shrink)

There seems to be a widespread conviction — evidenced, for example, in the work of Mackie, Dawkins and Sober — that it is Darwinian rather than Humean considerations which deal the fatal logical blow to arguments for intelligent design. I argue that this conviction cannot be well-founded. If there are current logically decisive objections to design arguments, they must be Humean — for Darwinian considerations count not at all against design arguments based upon apparent cosmological fine-tuning. I argue, (...) further, that there are good Humean reasons for atheists and agnostics to resist the suggestion that apparent design — apparent biological design and/or apparent cosmological fine-tuning — establishes (or even strongly supports) the hypothesis of intelligent design. (shrink)

In this paper, we discuss three probabilistic arguments for the existence of multiple universes. First, we provide an analysis of total evidence and use that analysis to defend Roger White's "this universe" objection to a standard fine-tuning argument for multiple universes. Second, we explain why Rodney Holder's recent cosmological argument for multiple universes is unconvincing. Third, we develop a "Cartesian argument" for multiple universes. While this argument is not open to the objections previously noted, (...) we show that, given certain highly plausible assumptions about evidence and epistemic probability, the proposition which it treats as evidence cannot coherently be regarded as evidence for anything. This raises the question of whether to reject the assumptions or accept that such a proposition cannot be evidence. (shrink)

Proponents of the this-universe objection to fine-tuning arguments for a multiverse claim that while the multiverse hypothesis raises the probability that some universe is fine-tuned for life, it fails to raise the probability that this one is. Because that is so, they further argue, those who take the fine-tuning of this universe as evidence for a multiverse are guilty of a probabilistic fallacy. Some opponents of the this-universe objection contend that it turns on contentious assumptions (...) regarding the essential properties of universes and agents. In particular, it is alleged to turn on the assumption that universes fail to have their nomic properties essentially as well as on the assumption that we could not have existed in other universes. I argue by contrast that the this-universe objection does not depend on these assumptions. (shrink)

The fine-tuning argument can be used to support the Many Universe hypothesis. The Inverse Gambler’s Fallacy objection seeks to undercut the support for the Many Universe hypothesis. The objection is that although the evidence that there is life somewhere confirms Many Universes, the specific evidence that there is life in this universe does not. I will argue that the Inverse Gambler’s Fallacy is not committed by the fine-tuning argument. The key issue is the procedure (...) by which the universe with life is selected for observation. Once we take account of the procedure, we find that the support for the Many Universe hypothesis remains. (shrink)

Several physicists, among them Hawking, Page, Coule, and Carroll, have argued against the probabilistic intuitions underlying fine-tuning arguments in cosmology and instead propose that the canonical measure on the phase space of Friedman-Robertson-Walker space-times should be used to evaluate fine-tuning. They claim that flat space-times in this set are actually typical on this natural measure and that therefore the flatness problem is illusory. I argue that they misinterpret typicality in this phase space and, moreover, that no (...) conclusion can be drawn at all about the flatness problem by using the canonical measure alone. (shrink)

How should we update our beliefs when we learn new evidence? Bayesian confirmation theory provides a widely accepted and well understood answer – we should conditionalize. But this theory has a problem with self-locating beliefs, beliefs that tell you where you are in the world, as opposed to what the world is like. To see the problem, consider your current belief that it is January. You might be absolutely, 100%, sure that it is January. But you will soon believe it (...) is February. This type of belief change cannot be modelled by conditionalization. We need some new principles of belief change for this kind of case, which I call belief mutation. In part 1, I defend the Relevance-Limiting Thesis, which says that a change in a purely self-locating belief of the kind that results in belief mutation should not shift your degree of belief in a non-self-locating belief, which can only change by conditionalization. My method is to give detailed analyses of the puzzles which threaten this thesis: Duplication, Sleeping Beauty, and The Prisoner. This also requires giving my own theory of observation selection effects. In part 2, I argue that when self-locating evidence is learnt from a position of uncertainty, it should be conditionalized on in the normal way. I defend this position by applying it to various cases where such evidence is found. I defend the Halfer position in Sleeping Beauty, and I defend the Doomsday Argument and the Fine-Tuning Argument.

Where did we come from? Why are we here? Where are we going? How should we live? I am sure that whoever is reading my words now has probably, at least once, asked these existential questions [1]. Among them, which one resonates the most? Probably the first question. You are not the only one since it has occupied minds of mankind since the dawn of history. But, why does it have such significance? Simply because its answer impacts everything else including (...) the other three questions. Our lives would become profoundly different based on our answer. There are only two possible answers, each of which has proponents. Theists give the affirmative answer while atheists give the negative one. This controversy involves both philosophical and scientific arguments. The scope of this paper will revolve more around philosophical argumentation than empirical scientific dialogue, into which it shall not dive deeply. The paper gathers different types of arguments, cosmological, moral, and fine-tuning arguments. This way, it introduces a reader new to the controversy to the types of arguments used, and, to readers familiar with the controversy, it gives insight about each type of argument through criticism. Each argument type has a lot of details. However, I care more about presenting the core of each type. My aim in this paper is equipping the reader with a firm foundation for their future search in pursuit of the truth. The main focus shall be on the existence of a first cause. Nonetheless, there shall be also a brief discussion about its attributes. The paper’s methodology for each type of argument is showing evidence for both theistic and atheistic views. Then a collective critical evaluation of each side’s arguments to show which side argues more soundly. (shrink)

In his essay, "Fine-Tuning and Multiple Universes", Roger White examines the extent to which a multiple-universe hypothesis lessens the ’surprisingness’ that our universe should be life-sustaining. White offers two main conclusions. His first conclusion -- that the existence of our world is not itself evidence for the existence of multiple universes -- is sound. However, his second conclusion is that, on the hypothesis that multiple universes exist, the further hypothesis of an intelligent designer does not lesson the surprisingness (...) that our universe should be life-permitting. This second conclusion, which would undercut most design arguments, is shown to rest on a mistake. (shrink)

Often, the possibility of a multiverse is given as a defeater for the anthropic argument: if there are many, possibly even an infinite number of worlds, then the probability of having a life-permitting world is no longer low. This article shows that the possibility of a multiverse doesn’t defeat the anthropic argument.

In this article, I will discuss some of the arguments for and against the existence of God, in particular the monotheistic God believed in the Abramahamic religions (Judiasm, Islam, and Christianity) as well as Babism, the Bahai Faith, and Sikhism. Arguments for the existence of God try to argue that either God exists (based on other things people agree with) or that belief in God is reasonable. Arguments against the existence of God try to argue that the existence of God (...) leads to some contradiction or other absurdity. (shrink)

(This is for the Cambridge Handbook of Analytic Philosophy, edited by Marcus Rossberg) In this handbook entry, I survey the different ways in which formal mathematical methods have been applied to philosophical questions throughout the history of analytic philosophy. I consider: formalization in symbolic logic, with examples such as Aquinas’ third way and Anselm’s ontological argument; Bayesian confirmation theory, with examples such as the fine-tuning argument for God and the paradox of the ravens; foundations of mathematics, (...) with examples such as Hilbert’s programme and Gödel’s incompleteness theorems; social choice theory, with examples such as Condorcet’s paradox and Arrow’s theorem; ‘how possibly’ results, with examples such as Condorcet’s jury theorem and recent work on intersectionality theory; and the application of advanced mathematics in philosophy, with examples such as accuracy-first epistemology.

It is one thing to hold that merely statistical evidence is _sometimes_ insufficient for rational belief, as in typical lottery and profiling cases. It is another thing to hold that merely statistical evidence is _always_ insufficient for rational belief. Indeed, there are cases where statistical evidence plainly does justify belief. This project develops a dispositional account of the normativity of statistical evidence, where the dispositions that ground justifying statistical evidence are connected to the goals (= proper function) of objects. There (...) are strong intuitive motivations for doing this. For we can turn almost any case of _non-justifying_ merely statistical evidence into a case of _justifying_ merely statistical evidence by adding information about the dispositions and goals of the objects involved. The resulting view not only helps us understand when and why merely statistical evidence is normatively significant, but it also helps us understand how statistical evidence relates to more standard forms of evidence (perceptual, testimonial). The emerging view also has surprising applications, as it imposes limitations on the epistemic value of fine-tuning arguments for theism as well as undermines a standard class of case-based arguments for moral encroachment.

Peter Millican and Branden Thornhill-Miller have recently argued that contradictions between different religious belief systems, in conjunction with the host of defeaters based on empirical research concerning alleged sources of evidence for ‘perceived supernatural agency’, render all ‘first-order’, that is actual, religious traditions positively irrational, and a source of discord on a global scale. However, since the authors recognise that the ‘secularisation thesis’ appears to be incorrect, and that empirical research provides evidence that religious belief also has beneficial individual and (...) social effects, they put forward a hypothesis of a ‘second-order religious belief ’, with Universalist overtones and thus free of intergroup conflict, and free of irrationality, since supported (solely) by the Fine-Tuning Argument. While granting most of their arguments based on empirical research and embracing the new paradigm of the atheism/religion debate implicit in their paper, I contend that Millican’s and Thornhill-Miller’s proposal is unlikely to appeal to religious believers, because it misconstrues the nature and grounds of religious belief. I suggest that their hypothesis may be refined by taking into account a view of axiologically grounded religious belief that I refer to as ‘agatheism’, since it identifies God or the Ultimate Reality with the ultimate good (to agathon).

This paper develops a new argument from consciousness to theism: the argument from psychophysical harmony. Roughly, psychophysical harmony consists in the fact that phenomenal states are correlated with physical states and with one another in strikingly fortunate ways. For example, phenomenal states are correlated with behavior and functioning that is justified or rationalized by those very phenomenal states, and phenomenal states are correlated with verbal reports and judgments that are made true by those very phenomenal states. We argue (...) that psychophysical harmony is strong evidence for theism (or, at least, strong evidence against atheism in its standard naturalistic form). (shrink)

This article defends the Doomsday Argument, the Halfer Position in Sleeping Beauty, the Fine-Tuning Argument, and the applicability of Bayesian confirmation theory to the Everett interpretation of quantum mechanics. It will argue that all four problems have the same structure, and it gives a unified treatment that uses simple models of the cases and no controversial assumptions about confirmation or self-locating evidence. The article will argue that the troublesome feature of all these cases is not self-location (...) but selection effects. (shrink)

Bayesian conceptions of evidence have been invoked in recent arguments regarding the existence of God, the hypothesis of multiple physical universes, and the Doomsday Argument. Philosophers writing on these topics often claim that, given a Bayesian account of evidence, our existence or something entailed by our existence (perhaps in conjunction with some background knowledge or assumption) may serve as evidence for each of us. In this paper, I argue that this widespread view is mistaken. The mere fact of one's (...) existence qua conscious creature cannot serve as evidence on the standard Bayesian conception of evidence because knowledge of one's existence is a necessary part of the background knowledge relative to which all epistemic probabilities are defined. It follows that some formulations of the fine-tuning argument (for theism or a multiverse), the argument from consciousness (for theism) and a rejoinder to the Doomsday argument are mistaken.

Aquinas’s Fifth Way is usually taken to be an adumbration of Paley-like design arguments. Paley-like design arguments have fallen on hard times over the past few centuries, and most contemporary defenders of design arguments in support of theism favor some version of the fine-tuning argument. But fine-tuning designarguments, like Paley’s design argument, are consistent with atomism. And all such arguments are vulnerable to the objection that, given a long enough stretch of time and a (...) sufficient number of universes, there would be no need to posit a designer. In this paper we argue that a deep understanding of Aquinas’s Fifth Way depends upon understanding his hylomorphic account of the nature of composite substance, an account that is inconsistent with atomism. We argue that if one grants hylomorphism, Aquinas’s Fifth Way is difficult to resist. And we defend Aquinas’s hylomorphism against several common objections. (shrink)

This paper is the product of an interdisciplinary, interreligious dialogue aiming to outline some of the possibilities and rational limits of supernatural religious belief, in the light of a critique of David Hume’s familiar sceptical arguments -- including a rejection of his famous Maxim on miracles -- combined with a range of striking recent empirical research. The Humean nexus leads us to the formulation of a new ”Common-Core/Diversity Dilemma’, which suggests that the contradictions between different religious belief systems, in conjunction (...) with new understandings of the cognitive forces that shape their common features, persuasively challenge the rationality of most kinds of supernatural belief. In support of this conclusion, we survey empirical research concerning intercessory prayer, religious experience, near-death experience, and various cognitive biases. But we then go on to consider evidence that supernaturalism -- even when rationally unwarranted -- has significant beneficial individual and social effects, despite others that are far less desirable. This prompts the formulation of a ”Normal/Objective Dilemma’, identifying important trade-offs to be found in the choice between our humanly evolved ”normal’ outlook on the world, and one that is more rational and ”objective’. Can we retain the pragmatic benefits of supernatural belief while avoiding irrationality and intergroup conflict? It may well seem that rationality is incompatible with any wilful sacrifice of objectivity. But in a situation of uncertainty, an attractive compromise may be available by moving from the competing factions and mutual contradictions of ”first-order’ supernaturalism to a more abstract and tolerant ”second-order’ view, which itself can be given some distinctive intellectual support through the increasingly popular Fine Tuning Argument. We end by proposing a ”Maxim of the Moon’ to express the undogmatic spirit of this second-order religiosity, providing a cautionary metaphor to counter the pervasive bias endemic to the human condition, and offering a more cooperation- and humility-enhancing understanding of religious diversity in a tense and precarious globalised age.

Motivated by examples, many philosophers believe that there is a significant distinction between states of affairs that are striking and therefore call for explanation and states of affairs that are not striking. This idea underlies several influential debates in metaphysics, philosophy of mathematics, normative theory, philosophy of modality, and philosophy of science but is not fully elaborated or explored. This paper aims to address this lack of clear explanation first by clarifying the epistemological issue at hand. Then it introduces an (...) initially attractive account for strikingness that is inspired by the work of Paul Horwich and adopted by a number of philosophers. The paper identifies two logically distinct accounts that have both been attributed to Horwich and then argues that, when properly interpreted, they can withstand former criticisms. The final two sections present a new set of considerations against both Horwichian accounts that avoid the shortcomings of former critiques. It remains to be seen whether an adequate account of strikingness exists. (shrink)

Could God have created a better universe? Well, the fundamental scientific laws and parameters of the universe have to be within a certain miniscule range, for a life-sustaining universe to develop: the universe must be ‘Fine Tuned’. Therefore the ‘embryonic universe’ that came into existence with the ‘big bang’ had to be either exactly as it was or within a certain tiny range, for there to develop a life-sustaining universe. If it is better that there exist a life-sustaining universe (...) than not, then it was better that the embryonic universe was one of this small set of very similar embryonic universes than that it was not. Furthermore, there are no firm grounds for claiming that of this small set of very similar embryonic universes, there is one which would have developed into a universe better than ours. Therefore there are no firm grounds for claiming that God could have created a better universe than ours. (shrink)

The idea that there are some facts that call for explanation serves as an unexamined premise in influential arguments for the inexistence of moral or mathematical facts and for the existence of a god and of other universes. This book is the first to offer a comprehensive and critical treatment of this idea. It argues that calling for explanation is a sometimes-misleading figure of speech rather than a fundamental property of facts.

Abstract: Classifying sea animals is an important problem in marine biology and ecology as it enables the accurate identification and monitoring of species populations, which is crucial for understanding and protecting marine ecosystems. This paper addresses the problem of classifying 19 different sea animals using convolutional neural networks (CNNs). The proposed solution is to use a pretrained MobileNetV2 model, which is a lightweight and efficient CNN architecture, and fine-tune it on a dataset of sea animals. The results of the (...) study show that the fine-tuned MobileNetV2 model is able to achieve an accuracy of 85% on the classification task, which is competitive with the state-of-the-art methods. Additionally, the study also found that data augmentation and regularization techniques such as dropout were important for preventing overfitting and improving the performance of the model. This study demonstrates the potential of using pretrained models and efficient CNN architectures for classifying sea animals, and it provides insights into the challenges and best practices for solving this important problem in marine biology and ecology.

Preprinted in God and the Problem of Evil(Blackwell 2001), ed. William Rowe. Many people deny that evil makes belief in atheism more reasonable for us than belief in theism. After all, they say, the grounds for belief in God are much better than the evidence for atheism, including the evidence provided by evil. We will not join their ranks on this occasion. Rather, we wish to consider the proposition that, setting aside grounds for belief in God and relying only on (...) the background knowledge shared in common by nontheists and theists, evil makes belief in atheism more reasonable for us than belief in theism. Our aim is to argue against this proposition. We recognize that in doing so, we face a formidable challenge. It’s one thing to say that evil presents a reason for atheism that is, ultimately, overridden by arguments for theism. It’s another to say that it doesn’t so much as provide us with a reason for atheism in the first place. In order to make this latter claim seem initially more plausible, consider the apparent design of the mammalian eye or the apparent fine-tuning of the universe to support life. These are often proposed as reasons to believe in theism. Critics commonly argue not merely that these supposed reasons for theism are overridden by arguments for atheism but rather that they aren’t good reasons for theism in the first place. Our parallel proposal with respect to evil and atheism is, initially at least, no less plausible than this proposal with respect to apparent design and theism. (shrink)

According to reductivist axiological perfectionism about well-being (RAP), well-being is constituted by the development and exercise of central human capacities. In defending this view, proponents have relied heavily on the claim that RAP provides a unifying explanation of the entries on the ‘objective list’ of well-being constituents. I argue that this argument fails to provide independent support for the theory. RAP does not render a plausible objective list unless such a list is used at every stage of theory development (...) to shape the details of the view. Absent such motivated fine-tuning, RAP even fails to provide a satisfying account of two supposed paradigm cases of perfectionist value: achievement and knowledge. Thus, if RAP is to be defended, it must be defended directly by providing reasons for accepting the axiological principle at its heart. It cannot be defended, indirectly, by pointing to its attractive implications. (shrink)
