Nicholas Rescher accepts the Principle of Sufficient Reason. In his Nature and Understanding, he gives two candidates for an ultimate explanation: a virtuously circular explanations of facts by laws and laws by facts, and an explanation of the world in terms of optimalism. I argue that the first of these depends on the second, and that the second could be improved by switching to a weaker optimalism or to a theistic explanation.

My understanding is that proximate explanations concern adaptive mechanism and that ultimate explanations concern adaptive rationale. Viewed in this light, the two kinds of explanation are quite distinct, but they interact in a complementary way to give a full understanding of biological adaptations. In contrast, Laland et al. (2013)—following a literal reading of Mayr (Science 134:1501–1506, 1961)—have characterized ultimate explanations as concerning any and all mechanisms that have operated over the course of an organism’s evolutionary (...) history. This has unfortunate consequences, such as allowing random drift to form the basis for ultimate explanations, and allowing proximate and ultimate explanations to bleed into each other until their distinction is meaningless. Here, I suggest Laland et al’s explanatory framework of “reciprocal causation” is not conducive to successful biological science, and that they have misunderstood key elements of the theory of Darwinian adaptation.

Tipler has previously argued that the nature of the universe is a matter of contingency rather than necessity. Now he argues that the existence of the universe can also be demonstrated to be a matter of necessity. I argue that both arguments are fatally flawed, and that neither supports the conclusion it is intended to establish.

This chapter explores the notion of necessary being and defends its explanatory significance. Even if we were to accept the traditional answer involving necessary being to the existence question, its wider significance may be challenged. While it is often incorporated into what has come to be known as the ‘cosmological argument from contingency’ for the existence of God, the bare idea of ‘necessary being’ seems quite thin. The chapter shows how the causal efficacy of a necessary being could figure into (...) an explanation of a contingent universe that affirms the universe's contingency that is an inevitable emanation of the necessary being without thereby conceding an ultimate explanatory surd. It enables one comfortably to steer clear of their necessitarian excesses even while retaining Schopenhauer's cab as a permanent mode of transportation on the way to a philosopher's paradise.

This is a book review of "Theism and Ultimate Explanation", by Timothy O'Connor.

Twentieth-century analytic philosophy was dominated by positivist antimetaphysics and neo-Humean deflationary metaphysics, and the nature of explanation was reconceived in order to fit these agendas. Unsurprisingly, the explanatory value of theist was widely discredited. I argue that the long-overdue revival of moralized, broadly neo-Aristotelian metaphysics and an improved perspective on modal knowledge dramatically changes the landscape. In this enriched context, there is no sharp divide between physics and metaphysics, and the natural end of the theoretician’s quest for a unified explanation (...) of the universe is God, an absolutely necessary, transcendent, and personal source of all contingent reality.

An expansive, yet succinct, analysis of the Philosophy of Religion – from metaphysics through theology. Organized into two sections, the text first examines truths concerning what is possible and what is necessary. These chapters lay the foundation for the book’s second part – the search for a metaphysical framework that permits the possibility of an ultimate explanation that is correct and complete. A cutting-edge scholarly work which engages with the traditional metaphysician’s quest for a true ultimate explanation of (...) the most general features of the world we inhabit Develops an original view concerning the epistemology and metaphysics of modality, or truths concerning what is possible or necessary Applies this framework to a re-examination of the cosmological argument for theism Defends a novel version of the Leibnizian cosmological argument.

There is a long lineage of philosophers concerned with coming to understand what explains everything broadly construed, or within a certain, restricted domain. We call such explanations ultimate explanations. Contemporarily, philosophers of a certain stripe have devoted much attention to the notion of fundamentality - that there is something which is without explanation. This Element explores some of the connections between fundamentality and ultimate explanations both contemporarily and historically.

Many philosophers and non-philosophers who reflect on the causal antecedents of human action get the impression that no agent can have morally relevant freedom. Call this the ‘non-existence impression.’ The paper aims to understand the (often implicit) reasoning underlying this impression. On the most popular reconstructions, the reasoning relies on the assumption that either an action is the outcome of a chance process, or it is determined by factors that are beyond the agent’s control or which she did not bring (...) about. I argue that arguments based on this premise fail to apply to some possible agents for whom the non-existence impression arises. On the alternative reconstruction I offer, the impression rests on the assumption that free will requires being involved in the ultimate explanation of one’s actions in a novel sense in which nothing can be involved in the ultimate explanation of anything.

Why is there something concrete rather than nothing? There are many suggestions to explain the existence of our world. But a suggestion can rule out all others that leave no concrete thing unexplained and throw up no further why question. One such ultimate explanation may only be found in something that can carry its own explanation within itself. In this article, I attempt to find one such explanation for all existence. A variant of self-explanation, namely self-subsumption—obtaining of a fact (...) literally in virtue of itself—may succeed in offering an ultimate explanation. One suggestion for a self-subsuming principle is that all possible worlds exist; however, it cannot satisfy us in our deep convictions concerning inductive inferences. Thus, I construct a self-subsuming ultimate explanation that is sufficient to fulfil the latter convictions. My hypothesis is based on the Axiological explanation and suggests that all intrinsically valuable possible worlds are required to exist; the latter fact also obtains as one of those intrinsically valuable possibilities and therefore is required to exist.

Shahn Majids philosophy of physics is critically presented. In his view the postulate that the universe should be self-explaining implies that no fundamental theory of physics is complete unless it is self-dual. Majid shows that bicrossproduct Hopf algebras have this property. His philosophy is compared with other approaches to the ultimate explanation and briefly analyzed.

Mayr’s distinction between proximate and ultimate explanation is justly famous, marking out a division of explanatory labor in biology. But while it is a useful heuristic in many cases, there are others in which proximate factors play an important role in shaping evolutionary trajectories, and in such cases, each project is sensitive to, and relevant to, the other. This general methodological claim is developed in the context of a discussion of human cooperation, and in particular, in a discussion on (...) the puzzling stability of the social contract over the Pleistocene–Holocene transition. For I argue that while we have a plausible account of the stability of Pleistocene cooperation, the stabilizing factors of the Pleistocene disappear in the Holocene, but cooperation does not. Holocene humans solved many collective action problems; cooperation did not collapse despite the apparent growth of free-riding elites. So the article combines a methodological claim about the interaction of proximate and evolutionary biology with a substantive one about the ecology of human cooperation. (shrink)

In this book Timothy O’Connor combines an investigation of modal epistemology with a fresh look at the traditional contingency version of the cosmological argument. The connection between the two parts is that he defends the practice of hypothesizing necessities for explanatory purposes, resisting those accounts that link possibility too closely to conceivability. This provides the context in which he asks the existence question, ‘Why do the particular contingent objects there are exist and undergo the events they do?’. Wisely avoiding the (...) Principle of Sufficient Reason he argues that the existence question is answered by, and only by, positing a necessary being that is a se in the sense of not depending on any other being.Another important feature of O’Connor's treatment is that he does not accept the difficult scholastic doctrine of divine simplicity, instead relying on the weaker thesis that the essential divine attributes are mutually entailing. Yet again he resists the thesis of the immutability of God, allowing that a necessary being can have accidental attributes and hence can change by acquiring knowledge of the free acts and/or random events that occur. In addition he combines the cosmological argument with the argument from fine-tuning so that the latter is used to support the thesis that the …. (shrink)

In books such as The World Within the World and The Anthropic Cosmological Principle, astronomer John Barrow has emerged as a leading writer on our efforts to understand the universe. Timothy Ferris, writing in The Times Literary Supplement of London, described him as "a temperate and accomplished humanist, scientist, and philosopher of science--a man out to make a contribution, not a show." Now Barrow offers the general reader another fascinating look at modern physics, as he explores the quest for a (...) single, unifying theory that will unlock nature's secrets. Theories of Everything is more than a history of science, more than a popular report on recent research and discoveries. Barrow provides a reflective, intelligent commentary on what a true Theory of Everything would be--its ingredients, its limitations, and what it could tell us about the universe. Never before, he writes, have physicists been so confident and so eager in the hunt for this "cosmic Rosetta Stone," as he calls it: "a single all-embracing picture of all the laws of nature from which the inevitability of all things seen must follow with unimpeachable logic." He lays out eight essential ingredients for a Theory of Everything and then explores each in turn, tracing how our knowledge has developed and how scientific discovery relates to our changing philosophy and religious thought in each area. Some of these ingredients are obvious--the laws of nature must be explained, for example, as well as its organizing principles--but others may be surprising, such as broken symmetries and selection biases. A Theory of Everything must account for the fact that the universe is "messy and complicated," he tells us, and for the limitations imposed by the questions we ask and the information we can obtain. The key lies in the remarkable capacity of mathematics to express the fundamental workings of the physical world--a language that the human mind is uniquely equipped to understand and manipulate. Barrow examines what mathematics actually is and describes how it makes the universe intelligible and provides a path to the underlying coherence in nature--which has led, in fact, to arguments that the universe itself is a vast computer. Yet even the most complete theory, even the most comprehensive mathematical explanation, cannot account for the uncomputable varieties of human experience and thought. "No non-poetic account of reality," he writes, "can be complete." In a field where the authorities converse in equations and mathematical notations, John Barrow speaks with the voice of thoughtful and knowledgeable humanist. Written with eloquence and expertise, Theories of Everything establishes a new perspective on humanity's efforts to explain the universe. (shrink)

Strong reciprocity has recently been subject to heated debate. In this debate, the “West camp” :231–262, 2011), which is critical of the case for SR, and the “Laland camp” :1512–1516, 2011, Biol Philos 28:719–745, 2013), which is sympathetic to the case of SR, seem to take diametrically opposed positions. The West camp criticizes advocates of SR for conflating proximate and ultimate causation. SR is said to be a proximate mechanism that is put forward by its advocates as an (...) class='Hi'>ultimate explanation of human cooperation. The West camp thus accuses advocates of SR for not heeding Mayr’s original distinction between ultimate and proximate causation. The Laland camp praises advocates of SR for revising Mayr’s distinction. Advocates of SR are said to replace Mayr’s uni-directional view on the relation between ultimate and proximate causes by the bi-directional one of reciprocal causation. The paper argues that both the West camp and the Laland camp misrepresent what advocates of SR are up to. The West camp is right that SR is a proximate cause of human cooperation. But rather than putting forward SR as an ultimate explanation, as the West camp argues, advocates of SR believe that SR itself is in need of ultimate explanation. Advocates of SR tend to take gene-culture co-evolutionary theory as the correct meta-theoretical framework for advancing ultimate explanations of SR. Appearances notwithstanding, gene-culture coevolutionary theory does not imply Laland et al.’s notion of reciprocal causation. “Reciprocal causation” suggests that proximate and ultimate causes interact simultaneously, while advocates of SR assume that they interact sequentially. I end by arguing that the best way to understand the debate is by disambiguating Mayr’s ultimate-proximate distinction. I propose to reserve “ultimate” and “proximate” for different sorts of explanations, and to use other terms for distinguishing different kinds of causes and different parts of the total causal chain producing behavior.

This paper is a review of the cosmological argument that Tim O'Connor defends in "Theism and Ultimate Explanation".

Timothy O’Connor presents a novel and powerful version of the cosmological argument from contingency. What distinguishes his argument is that it does not depend on the Principle of Sufficient Reason. This version thus avoids powerful objections facing the Principle. We present and develop the argument, strengthening it in various ways. We fill in big gaps in the argument and answer criticisms. These include the criticisms that O’Connor considers as well as new criticisms. We explain how his replies to a Kantian (...) criticism and to the demand for contrastive explanation fail, and properly answer the criticism and the demand. We develop two new criticisms, the objection from opaqueness and the objection from constitution, and explain how these objections can be answered. (shrink)

This paper discusses attempts to explain why there are more than zero instances of the causal relation. In particular, it argues for the conclusion that theism is no better placed than naturalism to provide an "ultimate causal explanation".

The articles by Corlett, McKenna and Waller in the present issue call for some further enlightenment on Lehrer’s defense of classical compatibilism. Ultimate explanation in terms of a power preference, which is the primary explanation for choice, is now the central feature of his defense. This includes the premise that scientific determinism may fail to explain our choices. Sylvain Bromberger showed that nomological deduction is not sufficient for explanation. A power preference, which is by definition a preference over alternatives, (...) is the primary explanation when the power preference explains the choice without the need to appeal to anything else, including even anything that explains it. The author notes that explanation is not generally transitive. The power preference must stand alone as an ultimate explanation independent of other explanations. It is thus the ultimate preference over alternatives of choice. (shrink)

Kareem Khalifa’s Understanding, Explanation, and Scientific Knowledge is a splendid book, written in a beautiful and accessible style. It provides the ultimate articulation of his account of explanatory understanding that I am sure will be regarded as one of the landmark publications on the topic of scientific understanding. Many of the central questions regarding scientific understanding are treated from different perspectives in the book. Such questions are: Does understanding require explanations? Must it consist of mostly true information? Is (...) it a species of knowledge? -/- I cannot do justice to all the intricate details of Khalifa’s arguments in a short piece like this, so I will focus on discussing his main line of argument and some of the most salient questions that are addressed in the book, instead of summarizing and commenting on each chapter.

We propose an approach reconciling the ultimate-level explanations proposed by Savage et al. and Mehr et al. as to why music evolved. We also question the current adaptationist view of culture, which too often fails to disentangle distinct fitness benefits.

The ultimate source of explanation in biology is the principle of natural selection. Natural selection means differential reproduction of genes and gene combinations. It is a mechanistic process which accounts for the existence in living organisms of end-directed structures and processes. It is argued that teleological explanations in biology are not only acceptable but indeed indispensable. There are at least three categories of biological phenomena where teleological explanations are appropriate.

Scientists and laypeople alike use the sense of understanding that an explanation conveys as a cue to good or correct explanation. Although the occurrence of this sense or feeling of understanding is neither necessary nor sufficient for good explanation, it does drive judgments of the plausibility and, ultimately, the acceptability, of an explanation. This paper presents evidence that the sense of understanding is in part the routine consequence of two well-documented biases in cognitive psychology: overconfidence and hindsight. In light of (...) the prevalence of counterfeit understanding in the history of science, I argue that many forms of cognitive achievement do not involve a sense of understanding, and that only the truth or accuracy of an explanation make the sense of understanding a valid cue to genuine understanding.

The question whether the universe has existed for an infinite or only a finite time, along with the question whether a causal series might go back infinitely far into the past, has loomed large in attempts to prove the existence of God. These questions, together with that of the extent of the future, are now discussed. They lead us to consider the principle of sufficient reason and to ask whether there can be any ultimate explanations, whether the regress (...) of explanations can ever be brought to a satisfactory end.

Recent evolutionary studies on cooperation devote specific attention to non-verbal expressions of emotions. In this paper, I examine Robert Frank’s popular attempt to explain emotions, non-verbal markers and social behaviours. Following this line of work, I focus on the green-beard explanation of social behaviours. In response to the criticisms raised against this controversial ultimate explanation, based on resources found in Frank’s work, I propose an alternative red-beard explanation of human sociality. The red-beard explanation explains the emergence and evolution of (...) emotions, a proximate cause, rather than patterns of behaviour. In contrast to simple evolutionary models that invoke a green-beard mechanism, I demonstrate that the red-beard explanation can be evolutionary stable. Social emotions are a common cause of a social behaviour and a phenotypic marker and therefore cooperative behaviour cannot be suppressed without also changing the marker. (shrink)

This article deals with a type of functional explanation, viability explanation, that has been overlooked in recent philosophy of science. Viability explanations relate traits of organisms and their environments in terms of what an individual needs to survive and reproduce. I show that viability explanations are neither causal nor historical and that, therefore, they should be accounted for as a distinct type of explanation.

Knives, birds' wings, and mountain slopes are used for certain purposes: cutting, flying, and climbing. A bird's wings have in common with knives that they have been 'designed' for the purpose they serve, which purpose accounts for their existence, whereas mountain slopes have come about by geological processes independently of their uses for climbing. A bird's wings differ from a knife in that they have not been designed or produced by any conscious agent; rather, the wings, like the slopes, are (...) outcomes of natural processes without any intentional causation. Evolutionary biologists use teleological language and teleological explanations. I propose that this use is appropriate, because teleological explanations are hypotheses that can be subject to empirical testing. The distinctiveness of teleological hypotheses is that they account for the existence of a feature in terms of the function it serves; for example, wings have evolved and persist because flying is beneficial to birds by increasing their chances of surviving and reproducing. Features of organisms that are explained with teleological hypotheses include structures, such as wings; processes, such as development from egg to adult; and behaviours, such as nest building. A proximate explanation of these features is the function they serve; an ultimate explanation that they all share is their contribution to the reproductive fitness of the organisms. I distinguish several kinds of teleological explanations, such as natural and artificial, as well as bounded and unbounded, some of which but not others apply to biological explanations. (shrink)

The aim of this paper is threefold. First, I defend the view that for Aristotle ethical inquiry, like all philosophical inquiry, is in the business of seeking scientific explanations. This defense will require (in section II) first describing the basic structure of such explanations and then showing how those explanations can either be found in or endorsed by Aristotle’s ethics. My description of scientific explanation should be relatively uncontroversial, and my subsequent discussion of scientific explanations in (...) Aristotle’s ethics is intended to help us see more clearly just what sorts of things are to count as “the thats” and “the whys” in ethical inquiry. The second aim of my paper is (in section III) to interpret anew the two thorny passages in which Aristotle discusses the role of scientific explanation in ethics. My interpretations further support the view that scientific explanations play a central role in Aristotle’s ethics, but they do so in a way that corrects textual misunderstandings made by scholars who share that view. Lastly (in section IV), I explain how Aristotle thinks scientific explanations in ethics can help us live better lives. Aristotle insists that the ultimate goal of ethics is to become good (EN I.3, 1095a5-6; II.2, 1103b26-29; X.9, 1179a35-b4), and so if scientific explanations are, indeed, necessary for ethics, then they must somehow help achieve that goal.

Scientific explanation in terms of laws and initial conditions (or better, in terms of objects with powers and liabilities) is contrasted with personal explanation in terms of agents with powers and purposes. In each case the factors involved in explanation may themselves be explained, and infinite regress of explanation is logically possible. There can be no absolute explanation of phenomena, which is explanation in terms of the logically necessary; but there can be ultimate explanation which is explanation in terms (...) of factors which themselves have no explanation. Our normal criteria of explanation suggest that the explanation of the universe lies in the action of God. (shrink)

Explanation and understanding are intimately connected notions, but the nature of that connection has generally not been considered a topic worthy of serious philosophical investigation. Most authors have avoided making reference to the notion of understanding in their accounts of explanation because they fear that any mention of the epistemic states of the individuals involved compromises the objectivity of explanation. Understanding is a pragmatic notion, they argue, and pragmatics should be kept at a safe distance from the universal features of (...) explanation. My main contention in this dissertation is that there is a sense in which it is meaningful and useful to talk about objective understanding, and that to characterize this notion it is necessary to formulate an account of objective explanation that makes reference to the beliefs and epistemic goals of the participants in a cognitive enterprise. ;My account of explanation is based on the belief-doubt model of inquiry first proposed by Peirce. Using the tools provided by decision theory, and the models of belief revision developed by Isaac Levi and by Alchourron, Gardenfors, and Makinson, I analyze the objective and pragmatic conditions that a piece of information must fulfill to be both explanatory and epistemically useful to an inquiring agent. The objective basis for an explanation is provided by the relation of probabilistic relevance that the fact described by the explanans bares to the fact described by the explanandum. But an explanation is much more than its foundation. As an epistemological notion, a potential explanation can only be a bona fide explanation if it becomes part of inquiry, that is, if an agent or a group of agents can see any value in it for their cognitive purposes. I provide a way to evaluate an explanation in terms of its credibility, its content, and its explanatory value. I argue that although an objective measure of the credibility and content of an explanation can be established, in many cases a complete determination of its explanatory value will ultimately depend on the interests and goals of the individual inquirers.

Human reason demands ultimate explanation; it demands a Because that admits of no further Because –something unconditioned. Pace dogmatic rationalist metaphysics, Kant concludes that theoretical reason must remain modest; it cannot know or cognize the existence of particular unconditioned entities (e.g. God or Leibnizian monads). The prevailing view goes even further; it maintains that theoretical reason cannot even know that something or other unconditioned exists. Yet I argue that Kant’s critique contains an ambitious conclusion: reason can know that something (...) unconditioned exists among things in themselves, even if it cannot know which particular unconditioned entities exist. I reconstruct Kant’s argument for this ambitious conclusion. On my reconstruction, the argument turns on a key metaphysical assumption about things in themselves: that they are completely determinate. And far from undermining Kant's case for modesty, I suggest, this assumption partly underlies it. (shrink)

It has often been claimed by philosophical theologians that the concept of God functions as an ‘ultimate explanation’ of the nature of the universe. In recent years, various theologians have regarded this notion of ‘ultimate explanation’ as one which has a central place in religious belief; and they construe the concept of God, at least in part, and sometimes mainly, as a concept which provides such an explanation. On the other hand, from the time of David Hume there (...) has been a long line of eminent philosophers who have found the whole idea of an ultimate explanation—something which completely explains absolutely everything—an incoherent one, analogous to the idea of the square of a circle. I think it worth trying to explore the possibilities and limits of the notion, and attempting to assess its importance for religious belief. First, I will briefly sketch the notion as it is found in recent work, and then offer an analysis of the notion of ‘explanation’ in general. Finally, I will try to ascertain the nature and limits of the notion in religion. (shrink)

This book develops and applies a novel kind of explanation: Empty-Base Explanation. While ordinary explanations have a tripartite structure involving an explanandum, a base of reasons why the explanandum obtains, and a link that connects the reasons to the explanandum, this book argues that there are explanations whose corresponding set of reasons is empty. This novel idea is located in the theoretical background of several fundamental philosophical issues. For example, it provides a convincing kind of ultimate or (...) final explanation that completely and conclusively explains a phenomenon without involving other phenomena for which further explanations could be demanded. -/- The possibility and fruitfulness of empty-base explanation is defended by general considerations from the theory of explanation, as well as concrete applications to (1) the practice of explanation by status, (2) the explanation of logical theorems, causal connections, and laws of nature, (3) self-explanation, (4) the use of IBE in metaphysics, (5) the notion of zero-ground (which it provides with a solid theoretical footing), and (6) ultimate explanation and its application to philosophical cosmology, the debate about the PSR, and the question of why there is anything at all.
