The claim that certain fundamental constants of nature are fine tuned for life and that this provides strong evidence for supernatural design is perhaps the best scientific argument for the existence of God since Paley’s watch. Even atheist physicists find these so called “anthropic coincidences” difficult to explain and need to invoke the Weak Anthropic Principle and multiple universes to do so. Certainly if there are many universes, fine tuning is simple. Our form of life was fined (...) tuned to our universe by evolution. While multiple universes are expected from modern cosmological theories, theists and some scientists object that invoking the unobservable is not science. Of course, God is unobservable too, so the best theists can claim is a standoff. This is the first in a series of columns based on a book in the works that attempts to show that the apparent fine tuning of fundamental constants can be understood from basic physics without invoking multiple universes. In some cases the explanation is provable. In other cases, it is not provable but plausible. Fine tuning by design is a God of the Gaps argument. The proponent has the burden if proving that no possible natural explanation can be found. Thus a plausible natural explanation is sufficient to defeat the argument. A list of thirty four parameters that seem to be fine tuned has been assembled by Rich Deem on the God and Science website. Several of Deem’s constants, such as the speed of light in a vacuum, c, Newton’s constant of gravity, G, and Planck’s constant, h, are just arbitrary numbers that are determined simply by the unit system you are using. They can be set equal to any number you want, except zero, with no impact on the physics. So no fine tuning can possibly be involved, just as the number p is not fine tuned. I will focus first on the five parameters that have the most significance because, if interpreted correctly, they seem to pretty much rule out almost any conceivable kind of life without fine tuning: · Ratio of electrons to protons · Ratio of electromagnetic force to gravity Expansion rate of the universe · Mass density of the universe · Cosmological constant I will admit that the features a universe would have for slightly different values of these parameters, all other parameters remaining the same, would render unlikely any form of life even remotely like ours, that is, one that is based on a lengthy process, chemical or otherwise, by which complex matter evolved from simpler matter. Let me discuss each in turn, with the last, the most difficult, reserved for a future column.. (shrink)

If the physical constants, initial conditions, or laws of nature in our universe had been even slightly different, then the evolution of life would have been impossible. This observation has led many philosophers and scientists to ask the natural next question: why is our universe so "fine-tuned" for life? The debates around this question are wide-ranging, multi-disciplinary, complicated, technical, and heated. This study is a comprehensive investigation of these debates and the many metaphysical and epistemological questions raised by (...) class='Hi'>cosmological fine-tuning. Waller's study reaches two significant and controversial conclusions. First, he concludes that the criticisms directed at the "multiverse hypothesis" by theists and at the "theistic hypothesis" by naturalists are largely unsuccessful. Neither of these options can plausibly be excluded. Choosing between them seems to turn on primitive metaphysical intuitions. Second, in order to break the philosophical deadlock, Waller moves the debate from the level of universes to the level of possible worlds. Arguing that possible worlds are also "fine-tuned" in an important and interesting sense, Waller concludes that the only plausible explanation for the fine-tuning of the actual world is to posit the existence of some kind of "God-like-thing.".

Studies in astrophysical cosmology have served to reveal the incomprehensible fine-tuning of the fundamental constants and cosmological quantities which must obtain if a universe like ours is to be life-permitting. Traditionally, such fine-tuning of the universe for life would have been taken as evidence of divine design. William Dembski’s ’generic chance elimination argument’ provides a framework for evaluating the hypothesis of design with respect to the fine-tuning of the universe. On Dembski’s model the (...) key to a design inference is the elimination of the competing alternatives of physical necessity and chance. In debates over fine-tuning, the former is represented by a ’theory of everything’, which would eliminate or significantly reduce the improbabilities of fine-tuning. The latter takes the shape of the ’many worlds hypothesis’, according to which a ’world ensemble’ of universes exist, thus providing purchase for the ’anthropic principle’. This paper assesses the relative merit. (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.

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)

This chapter considers two types of fine‐tuning, those dealing with the initial conditions of the universe and those based on fixed parameters. Three approaches have been taken to argue that fine‐tuning does not need any special explanation. The first is an appeal to coincidence. The second is that the data are biased by our own observations. The third has to do with the nature of probability itself. The chapter assesses each of these objections in detail. Many (...) naturalistic explanations have been offered for fine‐tuning. The chapter considers the three most important ones. The first is that future discoveries might show that fine‐tuning was not improbable after all. The second is that other life‐permitting ranges for the fine‐tuned constants (FTCs) might exist, allowing for exotic forms of life unlike ours. The third is that we might live in a multiverse of many different universes all with different values of FTCs. (shrink)

Fine-tuning in physics and cosmology is often used as evidence that a theory is incomplete. For example, the parameters of the standard model of particle physics are “unnaturally” small, which has driven much of the search for physics beyond the standard model. Of particular interest is the fine-tuning of the universe for life, which suggests that our universe’s ability to create physical life forms is improbable and in need of explanation, perhaps by a multiverse. This claim (...) has been challenged on the grounds that the relevant probability measure cannot be justified because it cannot be normalized, and so small probabilities cannot be inferred. We show how fine-tuning can be formulated within the context of Bayesian theory testing in the physical sciences. The normalizability problem is seen to be a general problem for testing any theory with free parameters, and not a unique problem for fine-tuning. Physical theories in fact avoid such problems in one of two ways. Dimensional parameters are bounded by the Planck scale, avoiding troublesome infinities, and we are not compelled to assume that dimensionless parameters are distributed uniformly, which avoids non-normalizability.

Aquinas' first proof for God's existence is usually interpreted as a metaphysical argument immune to any objections coming from empirical science. Connections to Aquinas' own historical understanding of physics and cosmology are ignored or downplayed. Nature and Nature's God proposes a natural philosophical interpretation of Aquinas' argument more sensitive to the broader context of Aquinas' work and yielding a more historically accurate account of the argument. Paradoxically, the book also shows that, on such an interpretation, Aquinas' argument is not (...) only consistent with modern science, but actually confirmed by the history of science, from classical mechanics through 19th century thermodynamics to contemporary cosmology. The first part of the book considers Aquinas' argument in its historical context, exploring the key principles that everything in motion is moved by something else and that an infinite regress of causes is impossible. The structure of the First Way is analyzed and the argument is connected both with Aquinas' Third Way-a new interpretation of which is also proposed-and Aquinas' second proof from motion in the Summa contra Gentiles. To complete the account of what natural philosophy-prior to metaphysics-can demonstrate about God, a chapter on Aquinas' teleological argument (the Fifth Way) is also included. The second part of the book tracks the history of modern science from Copernicus to today, showing how Aquinas' argument fared at each major turn. The first chapter shows how Newton's understanding of inertia and conservation of momentum supports the idea that motion cannot continue forever without God's causality, and integrates a modern understanding of inertia and gravity with the principles of Thomistic natural philosophy. The second chapter considers the first and second laws of thermodynamics, showing how they too support Aquinas' contention that motion cannot continue forever without God's causality. This chapter also discusses statistical mechanics and contemporary cosmology, demonstrating that science continues to support Aquinas' unmoved mover argument. The final chapter turns to modern biology as well as cosmological fine-tuning to show that modern science also continues to support Aquinas' teleological argument. The result is not only a satisfying defense of Aquinas' natural philosophical proofs for God's existence, but a primer on the broader project of integrating Thomistic natural philosophy with modern science.

Cosmological inflation is widely considered an integral and empirically successful component of contemporary cosmology. It was originally motivated by its solution of certain so-called fine-tuning problems of the hot big bang model, particularly what are known as the horizon problem and the flatness problem. Although the physics behind these problems is clear enough, the nature of the problems depends on the sense in which the hot big bang model is fine-tuned and how the alleged fine- (...) class='Hi'>tuning is problematic. Without clear explications of these, it remains unclear precisely what problems inflationary theory is meant to be solving and whether it does in fact solve them. I analyze the structure of these problems and consider various interpretations that may substantiate the alleged fine-tuning. On the basis of this analysis I argue that at present there is no unproblematic interpretation available for which it can be said that inflation solves the big bang model’s alleged fine-tuning problems.

The objective of this paper is analyzing to which extent the multiverse hypothesis provides a real explanation of the peculiarities of the laws and constants in our universe. First we argue in favor of the thesis that all multiverses except Tegmark’s “mathematical multiverse” are too small to explain the fine tuning, so that they merely shift the problem up one level. But the “mathematical multiverse" is surely too large. To prove this assessment, we have performed a number of (...) experiments with cellular automata of complex behavior, which can be considered as universes in the mathematical multiverse. The analogy between what happens in some automata (in particular Conway’s “Game of Life") and the real world is very strong. But if the results of our experiments can be extrapolated to our universe, we should expect to inhabit—in the context of the multiverse—a world in which at least some of the laws and constants of nature should show a certain time dependence. Actually, the probability of our existence in a world such as ours would be mathematically equal to zero. In consequence, the results presented in this paper can be considered as an inkling that the hypothesis of the multiverse, whatever its type, does not offer an adequate explanation for the peculiarities of the physical laws in our world.

I try to revive, and possibly reconcile, a debate started a few years ago, about the relative roles of a bare cosmological constant and of a vacuum energy, by taking the attitude to try to get the most from the physics now available as established. I notice that the bare cosmological constant of the Einstein equations, which is there ever since GR emerged, is actually constrained (if not measured) indirectly combining the effective cosmological constant observed now, as (...) given by ΛCDM Precision Cosmology, with the cumulative vacuum contribution of the particles of the Standard Model, SM. This comes out when the vacuum energy is regularized, as given by many Authors, still within well established Quantum Field Theory, QFT, but without violating Lorentz invariance. The fine tuning, implied by the compensation to a small positive value of the two large contributions, could be seen as offered by Nature, which provides one more fundamental constant, the bare Lambda. The possibility is then discussed of constraining (measuring) directly such a bare cosmological constant by the features of primordial gravitational wave signals coming from epoch’s precedent to the creation of particles. I comment on possibilities that would be lethal, that is if the vacuum does not gravitate. This last issue is often raised, and I discuss the current situation about. Finally a hint is briefly discussed for a possible “bare Lambda inflation” process. (shrink)

Many theists regard the claim that certain fundamental constants of nature are fine-tuned for life as the best scientific argument for the existence of God since Paley’s watch. Even atheist physicists find these so-called “anthropic coincidences” difficult to explain naturally and many think they need to invoke multiple universes and the so-called “anthropic principle” to do so. Certainly if there are many universes, fine-tuning is simple. Our universe is not fine-tuned for life. Life is fine-tuned (...) to our universe. While multiple universes are expected from modern cosmological theories, theists and some scientists object that invoking the unobservable is not science. Of course, God is unobservable too, so the best theists can claim is a standoff. (shrink)

"Multiverse" cosmologies imagine our universe as just one of a vast number of others. While this idea has captivated philosophy, religion, and literature for millennia, it is now being considered as a scientific hypothesis--with different models emerging from cosmology, quantum mechanics, and string theory. Beginning with ancient Atomist and Stoic philosophies, Mary-Jane Rubenstein links contemporary models of the multiverse to their forerunners and explores the reasons for their recent appearance. One concerns the so-called fine-tuning of the universe: nature's (...) constants are so delicately calibrated that it seems they have been set just right to allow life to emerge. For some thinkers, these "fine-tunings" are evidence of the existence of God; for others, however, and for most physicists, "God" is an insufficient scientific explanation. Hence the allure of the multiverse: if all possible worlds exist somewhere, then like monkeys hammering out Shakespeare, one universe is bound to be suitable for life. Of course, this hypothesis replaces God with an equally baffling article of faith: the existence of universes beyond, before, or after our own, eternally generated yet forever inaccessible to observation or experiment. In their very efforts to sidestep metaphysics, theoretical physicists propose multiverse scenarios that collide with it and even produce counter-theological narratives. Far from invalidating multiverse hypotheses, Rubenstein argues, this interdisciplinary collision actually secures their scientific viability. We may therefore be witnessing a radical reconfiguration of physics, philosophy, and religion in the modern turn to the multiverse. (shrink)

Contemporary physics and cosmology have accumulated a great deal of empirical evidence for the claim that in order for our universe to contain life, an array of incredibly precise laws, constants, and specific initial conditions had to be in place. The minuscule odds of this happening purely by chance have prompted some Christian thinkers to suggest that this can be seen as novel evidence that the universe was fine-tuned specifically to give rise to biological life. And yet some Christian (...) thinkers also wish to make the case that molecular biology provides new evidence to the effect that life could not have arisen naturally in our universe, but rather that the origin of life required additional special divine intervention. There is at least a prima facie tension between these two ideas. Relatedly, some have raised the question of why, if the universe were fine-tuned for life, it was also set up in such a way that the origin of life was preceded by more than 10 billion years of lifelessness. If life was the whole point, why the seeming delay? In this paper I suggest a way Christian thinkers might address both issues: namely, the cosmos was not fine-tuned for life, but merely for the possibility of life. Perhaps God wanted a universe in which biological organisms were possible but in which their non-existence was also a live possibility. I develop this solution in dialogue with related ideas arising from the demonologies of St. Augustine, Boethius, and St. Anselm. (shrink)

This paper is a sequel to my 'Theological Misinterpretations of Current Physical Cosmology' (Foundations of Physics [1996], 26 (4); revised in Philo [1998], 1 (1)). There I argued that the Big Bang models of (classical) general relativity theory, as well as the original 1948 versions of the steady state cosmology, are each logically incompatible with the time-honored theological doctrine that perpetual divine creation ('creatio continuans') is required in each of these two theorized worlds. Furthermore, I challenged the perennial theological doctrine (...) that there must be a divine creative cause (as distinct from a transformative one) for the very existence of the world, a ratio essendi. This doctrine is the theistic reply to the question: 'Why is there something, rather than just nothing?' I begin my present paper by arguing against the response by the contemporary Oxford theist Richard Swinburne and by Leibniz to what is, in effect, my counter-question: 'But why should there be just nothing, rather than something?' Their response takes the form of claiming that the a priori probability of there being just nothing, vis-à-vis the existence of alternative states, is maximal, because the non-existence of the world is conceptually the simplest. On the basis of an analysis of the role of simplicity in scientific explanations, I show that this response is multiply flawed, and thus provides no basis for their three contentions that (i) if there is a world at all, then its 'normal', natural, spontaneous state is one of utter nothingness or total non-existence, so that (ii) the very existence of matter, energy and living beings constitutes a deviation from the allegedly 'normal', spontaneous state of 'nothingness', and (iii) that deviation must thus have a suitably potent (external) divine cause. Related defects turn out to vitiate the medieval Kalam Argument for the existence of God, as espoused by William Craig. Next I argue against the contention by such theists as Richard Swinburne and Philip L. Quinn that (i) the specific content of the scientifically most fundamental laws of nature, including the constants they contain, requires supra-scientific explanation, and (ii) a satisfactory explanation is provided by the hypothesis that the God of theism willed them to be exactly what they are. Furthermore, I contend that the theistic teleological gloss on the 'Anthropic Principle' is incoherent and explanatorily unavailing. Finally, I offer an array of considerations against Swinburne's attempt to show, via Bayes's theorem, that the existence of God is more probable than not. (shrink)

It is commonplace in discussions of modern cosmology to assert that the early universe began in a special state. Conventionally, cosmologists characterize this fine-tuning in terms of the horizon and flatness problems. I argue that the fine-tuning is real, but these problems aren't the best way to think about it: causal disconnection of separated regions isn't the real problem, and flatness isn't a problem at all. Fine-tuning is better understood in terms of a measure (...) on the space of trajectories: given reasonable conditions in the late universe, the fraction of cosmological histories that were smooth at early times is incredibly tiny. This discussion helps clarify what is required by a complete theory of cosmological initial conditions. (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)

In earlier writings, I argued that neither of the two major physical cosmologies of the 20th century support divine creation, so that atheism has nothing to fear from the explanations required by these cosmologies. Yet theists ranging from Augustine, Aquinas, Descartes, and Leibniz to Richard Swinburne and Philip Quinn have maintained that, at every instant anew, the existence of the world requires divine creation ex nihilo as its cause. Indeed, according to some such theists, for any given moment t. (...) class='Hi'>God's volition that the-world-should-exist-at-t supposedly brings about its actual existence at t. In an effort to reestablish the current viability of this doctrine of perpetual divine conservation. Philip Quinn argued (1993) that it is entirely compatible with physical energy conservation in the Big Bang cosmology, as well as with the physics of the steady-state theories. But I now contend that instead, there is a logical incompatibility on both counts. Besides, the stated tenet of divine conservation has an additional defect: It speciously purchases plausibility by trading on the multiply disanalogous volitional explanations of human actions.

We begin with a discussion of the Borde-Guth-Vilenkin past-incompleteness theorem for inflationary universes and discuss its significance for various pre-big-bang inflationary scenarios in string cosmology, including landscape and cyclic ekpyrotic models. We then undertake a general critique of inflationary cosmology in respect of its stated goals and conclude with a critcal discussion of the string-theoretic multiverse as a "solution" to the problem of cosmological fine-tuning.

Theologians and philosophers of religion are increasingly interested in physics. From the fine-tuning of universal constants to quantum mechanics, relativity, and cosmology, physics is a surprisingly common subject where religion is involved. Bridging the gap between issues in religion and those in physics can be quite difficult, however. Fortunately, the philosophy of science provides a middle ground between the two disciplines. In this book, a philosopher of science provides a critical analysis of the ways in which physics is (...) brought into play in matters of religion. (shrink)

The discovery that the universe is fine-tuned for life ? a discovery to which the phrase ?the anthropic principle? is often applied ? has prompted much extra-cosmic speculation by philosophers, theologians, and theoretical physicists. Such speculation is referred to as extra-cosmic because an inference is made to the existence either of one unobservable entity that is distinct from the cosmos and any of its parts (God) or of many such entities (multiple universes). In this article a case is mounted (...) for the sceptical position that cosmic fine-tuning does not support an inference to anything extra-cosmic. To that end three definitions of ?fine-tuned for life? are proposed: the ?slight difference? definition, the (unconditional) probability definition, and John Leslie?s conditional probability definition. These three definitions are the only ones suggested by the relevant literature on fine-tuning and the anthropic principle. Since on none of them do claims of fine-tuning warrant an inference to something extracosmic, it is concluded that there is no definition of ?fine-tuned for life? serving this function. (shrink)

This new book by cosmologists Geraint F. Lewis and Luke A. Barnes is another entry in the long list of cosmology-centered physics books intended for a large audience. While many such books aim at advancing a novel scientific theory, this one has no such scientific pretense. Its goals are to assert that the universe is fine-tuned for life, to defend that this fact can reasonably motivate further scientific inquiry as to why it is so, and to show that the (...) multiverse and intelligent design hypotheses are reasonable proposals to explain this fine-tuning. This book's potential contribution, therefore, lies in how convincingly and efficiently it can make that case. (shrink)

For years theists have claimed that the constants of physics had to be finely tuned by God to the values that have for life in the universe to be possible. In my column of June, 2009 I showed that many of these claims are based on an improper analysis of the data. Even some of the competent scientists who write on this subject commit the fallacy of holding all the parameters constant and varying just one. When you allow all to (...) vary, you find that changes to one parameter can be easily compensated for by changes to another, leaving the ingredients for life in place. This point is also made nicely in a recent Scientific American cover story by Alejandro Jenkins and Gilad Perez. In this column I will discuss perhaps the most cited example of claimed fine-tuning, the Hoyle resonance. In 1953 the famous astronomer Fred Hoyle calculated that the production of carbon would not occur with sufficient probability unless that probability was boosted by the presence of an excited nuclear state of C12 at a very specific energy. In what appeared to be a remarkable victory for anthropic reasoning, Hoyle proposed that this previously unknown state must exist at about 7.7 MeV. (shrink)

This is response to Stephen Parrish’s article "Theodore Drange on the Fine-Tuning Argument: A Critique," ’Philosophia Christi’, Series 2, 1 (No. 2, 1999), which attacked a section of my book ’Nonbelief and Evil: Two Arguments for God’s Nonexistence’ (Amherst, NY: Prometheus Books, 1998). The Fine-Tuning Argument (FTA) maintains that the physical constants of our universe exhibit evidence of "fine-tuning" by an intelligent designer. In opposition, I suggest alternate explanations which are at least as good. (...) Here I defend my objections to FTA against Parrish’s critique, aiming to show that his defense of the argument is a failure. (shrink)

Physical force strengths, particle masses, the early cosmic expansion speed and many other factors seem "fine tuned for life". Had they been slightly different, life’s evolution would have been impossible. The situation resembles catching a fish with an apparatus unable to catch ones slightly differently sized. One explanation is that the lake contains fish of many different sizes: multiple universes with randomized characteristics, most of them unobservable because observers cannot evolve in them. Another is that God created a fish (...) of the right size, a universe able to generate observers. The article defends these explanations against numerous ingenious objections. (shrink)

The multiverse hypothesis is the leading alternative to the competing fine-tuning hypothesis. The multiverse dispels many aspects of the fine-tuning argument by suggesting that there are different initial conditions in each universe, varying constants of physics, and the laws of nature lose their known arbitrary values; thus, making the previous single-universe argument from fine- tuning incredibly weak. The position that will be advocated will be that a form of multiverse could exist and that any (...) level of Tegmark's multiverse does not circumvent the fine-tuning argument for the existence of a fine-tuner. An argument will be presented suggesting that the multiverse could strengthen the fine-tuning argument by narrowing down the parameters of the data to a more fundamental description needed for the multiverse to function as it does since it may be the case that some physical descriptions are not the same in every universe. That is, the task of explaining how the multiverse mechanism functions cannot be accounted for by the multiverse itself. Fine-tuning by a mind serves as a sufficient and best explanation for the data. (shrink)

Probability theory promises to deliver an exact and unified foundation for inquiry in epistemology and philosophy of science. But philosophy of religion is also fertile ground for the application of probabilistic thinking. This volume presents original contributions from twelve contemporary researchers, both established and emerging, to offer a representative sample of the work currently being carried out in this potentially rich field of inquiry. Grouped into five parts, the chapters span a broad range of traditional issues in religious epistemology. The (...) first three parts discuss the evidential impact of various considerations that have been brought to bear on the question of the existence of God. These include witness reports of the occurrence of miraculous events, the existence of complex biological adaptations, the apparent 'fine-tuning' for life of various physical constants and the existence of seemingly unnecessary evil. The fourth part addresses a number of issues raised by Pascal's famous pragmatic argument for theistic belief. A final part offers probabilistic perspectives on the rationality of faith and the epistemic significance of religious disagreement. (shrink)

In this paper I continue the investigation in Viaggiu, Viaggiu concerning my proposal on the nature of the cosmological constant. In particular, I study both mathematically and physically the quantum Planckian context and I provide, in order to depict quantum fluctuations and in absence of a complete quantum gravity theory, a semiclassical solution where an effective inhomogeneous metric at Planckian scales or above is averaged. In such a framework, a generalization of the well known Buchert formalism is obtained with (...) the foliation in terms of the mean value \\) of the time operator \ in a maximally localizing state \ of a quantum spacetime and in a cosmological context. As a result, after introducing a decoherence length scale \ where quantum fluctuations are averaged on, a classical de Sitter universe emerges with a small cosmological constant depending on \ and frozen in a true vacuum state, provided that the kinematical backreaction is negligible at that scale \. Finally, I analyse the case with a non-vanishing initial spatial curvature \ showing that, for a reasonable large class of models, spatial curvature and kinematical backreation \ are suppressed by the dynamical evolution of the spacetime.

I briefly defend the following claims in response to my critics: (1) We cannot make a principled division between features of contingent reality that do and features that don’t "cry our for explanation." (2) The physical data indicating fine-tuning provide confirmation of the hypothesis of a personal necessary cause of the universe over against an impersonal necessary cause, notwithstanding the fact that the probability of either hypothesis, if true, would be 1. (3) Theism that commits to God’s necessary (...) existence makes more sense than theism that denies it. (4) God is likely to have created an infinity of universes, and this conclusion helps with (though does not solve) the many problems of evil. (shrink)

Philosophers have postulated the existence of God to explain (I) why any contingent objects exist at all rather than nothing contingent, and (II) why the fundamental laws of nature and basic facts of the world are exactly what they are. Therefore, we ask: (a) Does (I) pose a well-conceived question which calls for an answer? and (b) Can God's presumed will (or intention) provide a cogent explanation of the basic laws and facts of the world, as claimed by (II)? (...) We shall address both (a) and (b). To the extent that they yield an unfavourable verdict, the afore-stated reasons for postulating the existence of God are undermined. As for question (I), in 1714, G. W. Leibniz posed the Primordial Existential Question (hereafter 'PEQ'): 'Why is there something contingent at all, rather than just nothing contingent?' This question has two major presuppositions: (1) A state of affairs in which nothing contingent exists is indeed genuinely possible ('the Null Possibility'), the notion of nothingness being both intelligible and free from contradiction; and (2) De jure, there should be nothing contingent at all, and indeed there would be nothing contingent in the absence of an overriding external cause (or reason), because that state of affairs is 'most natural' or 'normal'. The putative world containing nothing contingent is the so-called 'Null World'. As for (1), the logical robustness of the Null Possibility of there being nothing contingent needs to be demonstrated. But even if the Null Possibility is demonstrably genuine, there is an issue: Does that possibility require us to explain why it is not actualized by the Null World, which contains nothing contingent? And, as for (2), it originated as a corollary of the distinctly Christian precept (going back to the second century) that the very existence of any and every contingent entity is utterly dependent on God at any and all times. Like (1), (2) calls for scrutiny. Clearly, if either of these presuppositions of Leibniz's PEQ is ill founded or demonstrably false, then PEQ is aborted as a non-starter, because in that case, it is posing an ill-conceived question. In earlier writings (Grünbaum [2000], p. 5), I have introduced the designation 'SoN' for the ontological 'spontaneity of nothingness' asserted in presupposition (2) of PEQ. Clearly, in response to PEQ, (2) can be challenged by asking the counter-question, 'But why should there be nothing contingent, rather than something contingent?' Leibniz offered an a priori argument for SoN. Yet it will emerge that a priori defences of it fail, and that it has no empirical legitimacy either. Indeed physical cosmology spells an important relevant moral: As against any a priori dictum on what is the 'natural' status of the universe, the verdict on that status depends crucially on empirical evidence. Thus PEQ turns out to be a non-starter, because its presupposed SoN is ill founded! Hence PEQ cannot serve as a springboard for creationist theism. Yet Leibniz and the English theist Richard Swinburne offered divine creation ex nihilo as their answer to the ill-conceived PEQ. But being predicated on SoN, their cosmological arguments for the existence of God are fundamentally unsuccessful. The axiomatically topmost laws of nature (the 'nomology') in a scientific theory are themselves unexplained explainors, and are thus thought to be true as a matter of brute fact. But theists have offered a theological explanation of the specifics of these laws as having been willed or intended by God in the mode of agent causation to be exactly what they are. A whole array of considerations are offered in Section 2 to show that the proposed theistic explanation of the nomology fails multiply to transform scientific brute facts into specifically explained regularities. Thus, I argue for The Poverty of Theistic Cosmology in two major respects. (shrink)

Many physics parameters need to be precisely set in order for life to exist in our universe. Or so says the fine-tuning argument. That the actual values are just right for life, the argument concludes, is a fact in need of deep physical or metaphysical explanation. Perhaps, the story goes, the parameter values settings are a matter of divine design. Or perhaps they result from a selection effect given our place in the “multiverse”. However, a very different approach (...) to the problem is possible. One may argue that the fine-tuning is an artefact of theorizing: it is explicable as the precise balancing act necessary for compact, systematic representation in science. Given such an explanation and drawing on earlier work from a number of sources, this essay shows how fine-tuning is best understood as evidence for a non-governing conception of laws rather than for design or multiverse.

Richard Swinburne presents a substantially rewritten and updated edition of his most celebrated book. No other work has made a more powerful case for the probability of the existence of God.

In lieu of an abstract, here is a brief excerpt of the content:The 2004 Meeting of the Society for Buddhist-Christian StudiesFrances S. AdeneyThe 2004 meeting of the Society for Buddhist-Christian Studies was held in San Antonio, Texas, 19–20 November 2004. This year's theme was "Dealing with Illness and Promoting Healing: Buddhist and Christian Resources." During the first session panelists Laura Habgood Arsta, Jay McDaniel, and Beth Blizman presented Christian views on dealing with illness, and Rita Gross responded from a Buddhist (...) perspective. The second session focused Buddhist resources for promoting healing by panelists Francis Tsio and Grace Buford, with Laurel Curran presenting a Christian response.Laura Habgood Arsta presented research done by undergraduate students in border communities between the United States and Mexico. The topic was the connection between the Pentecostal movement and environmental health. Pentecostal Christianity (250–400 million members worldwide) emphasizes the signs that accompany the presence of Christ, evidenced by experiences of spirit baptism and faith healing.Their sample indicated that poor and minority people don't identify with the environmental movement until personal health problems emerge. One possible reason for Pentecostal religion thriving, according to this research, might be that exposure to toxins and poverty draws people to healing, a theological pillar of Pentecostalism. Religious services provide an emotional outlet and inspire self-confidence, which can become a mental health component of a healing solution. Women are free to share and lead services, finding leadership opportunities and a social group in churches. As an inexpensive alternative to medical care, healing in the Pentecostal church provides a sense of physical healing as well as help in overcoming addictions.Beth Blizman informed the group of the toxicity of the Lake Erie area of northern Ohio. Cancer is becoming normalized in this region, which has the highest level of multiple cancers in the United States. Beth feels called to heal her own body and become part of the healing process of that region. She argued that an attitude that disrespects the earth leads to disrespect of one another. "How can healing be found?" she asked. She discussed many resources from ancient monastics to modern women religious, from process and feminist thought to new cosmologies. Finally she connected [End Page 149] Audre Lourde's work on the rejection of difference to the bioregional studies that she has been doing on toxicity and illness.Jay McDaniels followed by giving a Christian perspective on Alzheimer's disease as an ecumenical Christian influenced by Buddhism. He addressed three questions that Christians ask in this situation. The first question is "Where is God now? Is God inside my loved one? How?" In response to this question, Jay outlined an evangelical view of God that understands God as a transcendent being, "way up there, watching from a distance." He contrasted this view with a process view of God as an "umbrella of compassion that envelops the world without smothering it." In this view, God is the great companion, sharing the confusion and anxiety of the ill person.So where is the person as they experience personality changes caused by the disease? Jay addressed this second question through process theology, stating that in process theology the person is defined in Buddhist terms, inheriting from the past and contributing to the future. A person is constantly in flux or transformation, so the person with illness may be a different person than they once were but can be embraced as the person that they are now. The multidimensional universe of process theology allows for a person to live "with one foot on earth and one foot in heaven."Help for dealing with Alzheimer's disease, Jay's third question, can be found in the Benedictine vow of obedience, stability, and ongoing conversion. The deepest need for those with Alzheimer's is to be with them, being available to others to listen. Stability is the vow to stay with the relationship through these changes. Ongoing conversion can come through Alzheimer's as those with this disease invite us into a space of creative imagination and a new kind of respect.Rita Gross responded to the three presentations by arguing that how one perceives a situation changes it tremendously. Two Buddhist principles that apply here are... (shrink)

Jan Greben criticized fine-tuning by taking seriously the idea that “nature is quantum mechanical”. I argue that this quantum view is limited, and that fine-tuning is real, in the sense that our current physical models require fine-tuning. Second, I examine and clarify many difficult and fundamental issues raised by Rüdiger Vaas’ comments on Cosmological Artificial Selection.

I argue that the standard way of formalizing the fine-tuning argument for design is flawed, and I present an alternative formalization. On the alternative formalization, the existence of life is not treated as the evidence that confirms design; instead it is treated as part of the background knowledge, while the fact that fine tuning is required for life serves as the evidence. I argue that the alternative better captures the informal line of thought that gives the (...) fine-tuning argument its intuitive plausibility, and I show that the alternative formalization avoids all of the most prominent objections to the fine-tuning argument, including the objection from observation selection effects, the problem of old evidence, the problem of non-normalizable probability measures and a further objection due to Monton. I conclude that the alternative formalization is the one that attention should be focused on. (shrink)

In this philosophical paper, we explore computational and biological analogies to address the fine-tuning problem in cosmology. We first clarify what it means for physical constants or initial conditions to be fine-tuned. We review important distinctions such as the dimensionless and dimensional physical constants, and the classification of constants proposed by Lévy-Leblond. Then we explore how two great analogies, computational and biological, can give new insights into our problem. This paper includes a preliminary study to examine the (...) two analogies. Importantly, analogies are both useful and fundamental cognitive tools, but can also be misused or misinterpreted. The idea that our universe might be modelled as a computational entity is analysed, and we discuss the distinction between physical laws and initial conditions using algorithmic information theory. Smolin introduced the theory of "cosmological natural selection" with a biological analogy in mind. We examine an extension of. (shrink)

Richard Swinburne presents a substantially rewritten and updated edition of his most celebrated book. No other work has made a more powerful case for the probability of the existence of God.

He claims (...) that while none of these arguments are deductively valid, they do give inductive support to theism and that, even when the argument from evil is weighed against them, taken together they offer good grounds to support the probability that there is a God. The overall structure of the discussion and its conclusion have been retained for this new edition, but much has been changed in order to strengthen the argumentation and to take account of Swinburne's subsequent work on the nature of consciousness and the problem of evil, and of the latest philosophical and scientific writing, especially in respect of the laws of nature and the argument from fine-tuning.

Some physical aspects of Teilhard's synthesis are focused upon and confronted with the recent achievements of physics and cosmology. The stuff of the universe, according to modern physical theories, has become something more similar to a structure or form than to inert pieces of material substratum. Directedness of time and history no longer seems to be an ontological a priori of any existence, but rather an outcome of finely tuned initial conditions. And the growth of complexity is now regarded as (...) a process emerging out of physical laws rather than a foreign element in the body of physics. The question is considered of how these results affect Teilhard de Chardin's vision of the world. (shrink)

We have known for a long time that there is complex, intelligent life. More recently we have discovered that the physics of our universe is fine-tuned so as to allow for the existence of such life. Call these two observations the Old Datum and the New Datum, respectively. Our question here is: once we know the Old Datum, does the New Datum provide additional evidence for the design hypothesis? I argue that it does not. Thus, there is an important (...) sense in which the much-touted fine-tuning of physics is irrelevant to debates about design. (shrink)

The twenty-one readings collected by Leslie address four main questions: Was there a Big Bang? Is our universe "fine-tuned" to life's needs such that the most minute changes would have made life-forms impossible? Are there multiple universes? Is there life elsewhere in the cosmos? A brief survey of a sampling of the readings will convey the scope of this volume.

This essay explores a simple argument for a Ground of Being, objections to it, and limitations on it. It is nonsensical to refer to Nothing in the sense of utter absence, hence nothing can be claimed to come from Nothing. If, as it seems, the universe, or any physical ensemble containing it, is past-finite, it must be caused by an uncaused Ground. Speculative many-worlds, pocket universes and multiverses do not affect this argument, but the quantum cosmologies of Alex Vilenkin, and (...) J. B. Hartle and Stephen Hawking, which claim that the universe came from literally nothing, would. I argue that their novel project cannot work for reasons both physical (their "nothing" is actually a vacuum state governed by eternal physical laws) and methodological (physical theory cannot explain the emergence of the physical per se). Thus my argument stands. However, as David Hume showed, a posteriori arguments like mine infer a creation, and Creator, of a certain character, namely, a stochastic concept of creation and a panentheistic, partly physical Creator lacking omniscience and omnipotence. Rather than undermining the cosmological argument, as Hume intended, these limitations liberate the concept of the Ground from unnecessary problems, as Hartshorne suggested. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:556 BOOK REVIEWS actions ag'ainst the subject as battery. A further problem with creating embryos for research is that so doing violates the rights of ·the person or person-to-be to its parents and family. Crea.ting these embryos treats them as means and as nothing more than scientifically interesting material, but with no rights against harmful assaults. University of Illinois Chanipaign-Urbana FR. ROBERT BARRY, O.P. Evolution ana Creation. Edited by (...) ERNAN MoMULLIN. Notre Dame, Indiana : Notre Dame Press, 1986. Pp. 304. $24.96 (cloth). This book offers a stimulating array of perspectives on the one thing about evolutionary theory that directly concerns Christian thinkers: its reconciliation with the Judeo-Christian account of creation. The essays were originally papers delivered at a symposium held at the University of Notr.e Dame. Besides bringing them together in a single volume, the editor, Ernan McMullin, has himself contributed a lucid introductory essay for the sake of historical context. Still, at the book's end, I found myself left with the question that books on this topic always seems to leave me with: Where are the philosophical and theological problems posed by evolutionary theory? To be sure, the cultural and historical impact of Darwin's theory raised questions of reconciliation between biblical claims and scientific evidence, but the perceived philosophical and theological problems were more apparent than real. What gave them bite was the absence of a proper understanding of the difference between philosophical and scientific knowledge created by the collapse of the Aristotelian system in the sixteenth century. The insufficiencies of the Aristotelian science, rendered glaring by the steady emergence of the new science, not only led to the rejection of Aristotelianism vn toto but left an intellectual vacuum which the new science filled. Soon this science was enshrined as the standard of all knowledge. This state of affairs understandably conferred upon the scientific challenge to Christian doctrine an absoluteness that seemed to demand a scientific defense of the biblical account of creation. When, however, the distinction between philosophical and scientific knowledge is observed (I speak here of a philosophy that is a realism), the challenge of evolutionary theories to Christian doctrine evaporates. What "challenges" remain are pseudo-scientific in that they are assertions of philosophical theories of materialism decked out in the clothes of science. Cases in point are the contributions to Evolution and Crea- BOOK REVIEWS 557 tion by John Leslie, "Modern Cosmology and the Creation of Life," James l!,. Ross, "Christians Get the Best of Evolution," and Phillip R. Sloan, " The Question of Natural Purpose." Leslie attempts to cast the design argument in a form that creation scientists would accept. What inspires the project is his fear that the standard objections to design arguments jeopardize scientific development. His is a creative and at times brilliant approach,to the defense of the design argument, which defense he unfortunately weakens, however, by failing to establish a clear line,of demarcation between science and philosophy. He argues that the emergence of life forms bespeaks a fine-tuning and delicacy of balance of nature's laws which demand explanation. He cites as the only plausible alternatives that either the universe is a product of design or there are multiple universes. For if you reject design in favor of proba.bility as the explanation for delicately balanced laws on which life depends, you must argue that this universe of ours is an occurrence of such and such a degree of probability, while other universes represent different probable occurences with different laws, etc. For example, " a 1 percent increase or decrease in the power of the strong nuclear force ruins stellar synthesis of carbon " and "for chemistry to be possible the mass of the neutron must exceed that of the proton, but by no more than approximately a tenth of 1 percent..." But Leslie finds the plausibility of the many universes account weakened by the "serious horizon problems": 66 For as far out as our telescopes can reach, our universe consists of particles with the same relative strengths, and so on. Suppose that these masses and strengths and such were settled probabilistically at some early stage. How came they to be... (shrink)

While written by a prominent and active scientist, this book is based on personal experience and biblical theology. It doesn't try to derive God s existence from science and it's critical of scientific inferences on the notion of God (Natural Theology). Cosmic fine-tuning and other coincidences are no proof of God, but are amazing, astounding and will never be fully explained. Amazement is the appropriate emotional perception of reality. The objective world is not a matter of course and (...) may well not exist at all; thus reality, at times, is experienced to be very special. Human life, the beauty of nature, the habitability of planet Earth can be considered undeserved gifts. In the light of these gifts, the universe is metaphorically interpreted and existentially believed as a divine Creation. Science cannot create such faith but can foster it. Is God necessary to explain the universe? Is the idea of a Creator excluded by modern science? Why continue speaking of a Creator and to believe (trust and hope) in His continuing creation when God cannot be demonstrated in scientific data? Arnold Benz, a renowned astrophysicist and Christian, insists that human perception reaches further than science and demonstrates this in various examples, personal, biblical, and literary.".

My purpose, in this paper, is to defend the claim that the fine-tuning argument suffers from the poor design worry. Simply put, the worry is this: if God created the universe, specifically with the purpose of bringing about moral agents, we would antecedently predict that the universe and the laws of nature, taken as a whole, would be well-equipped to do just that. However, in light of how rare a life-permitting universe is, compared to all the ways the (...) universe might be have been life-prohibiting given the laws of physics, strongly suggests that the universe was poorly designed for that purpose. This casts doubt on the claim that God has much to do with designing the universe. First, I introduce the fine-tuning argument, and second, I explain and defend the poor design worry against objections that, while apparently compelling, I argue are misleading. (shrink)

The universe appears fine-tuned for life. Bayesian confirmation theory is utilized to examine two competing explanations for this fine-tuning, namely design (theism) and the existence of many universes, in comparison with the ’null’ hypothesis that just one universe exists as a brute fact. Some authors have invoked the so-called ’inverse gambler’s fallacy’ to argue that the many-universes hypothesis does not explain the fine-tuning of ’this’ universe, but flaws in this argument are exposed. Nevertheless, the hypothesis (...) of design, being simpler, is arguably of higher prior probability and, therefore, to be preferred. The hypothesis of the single brute-fact universe is disconfirmed.

The focus of this research paper concerns the dialogue between science and theology. The current state of the dialogue involves a wide range of points of intersection that both pose and provoke questions concerning the very viability and coherence of such a dialogue. In particular, this paper examines the physicist/theologian, Robert John Russell's 'Creative Mutual Interaction' (CMI). The significance of the CMI diagram is that it names the basic interactions between science and theology and theology and science. These interactions are (...) presented as pathways, 8 in all, 5 of which flow from science to theology and 3 of which flow from theology to science. These pathways integrate a number of philosophical assumptions. These pathways can make scientists, theologians, and philosophers more aware of the philosophical assumptions at work between both theology and science. Russell, in his CMI, provides 8 paths to this interaction; 5 pathways where science informs theology and 3 by which theology informs science. In this thesis, I examine a test case of Russell's where he interacts the concepts of cosmology, eschatology, and bodily resurrection as it applies to Jesus Christ in New Testament Studies. (shrink)

Naturalism has been characterized both as a claim about what exists and as a commitment to a certain methodology. The fine - tuning argument for God’s existence presents a significant challenge to each way of characterizing naturalism. The claim naturalist faces the fact that the best response to the fine - tuning argument requires the existence of many universes that are not clearly naturalistic themselves. Method naturalism faces the challenge that it does not have the resources (...) to ground the preference of the many-world hypothesis to the designer hypothesis. (shrink)
