The epistemic arrow of time is the fact that our knowledge of the past seems to be both of a different kind and more detailed than our knowledge of the future. Just like with the other arrows of time, it has often been speculated that the epistemic arrow arises due to the second law of thermodynamics. In this paper, we investigate the epistemic arrow of time using a fully formal framework. We begin by defining a memory system as any physical (...) system whose present state can provide information about the state of the external world at some time other than the present. We then identify two types of memory systems in our universe, along with an important special case of the first type, which we distinguish as a third type of memory system. We show that two of these types of memory systems are time-symmetric, able to provide knowledge about both the past and the future. However, the third type of memory systems exploits the second law of thermodynamics, at least in all of its instances in our universe that we are aware of. The result is that in our universe, this type of memory system only ever provides information about the past. We also argue that human memory is of this third type, completing the argument. We end by scrutinizing the basis of the second law itself. This uncovers a previously unappreciated formal problem for common arguments that try to derive the second law from the “Past Hypothesis”, i.e., from the claim that the very early universe was in a state of extremely low entropy. Our analysis is indebted to prior work by one of us but expands and improves upon this work in several respects. (shrink)

Do the rich descriptions and narrative shapings of literature provide a valuable resource for readers, writers, philosophers, and everyday people to imagine and confront the ultimate questions of life? Do the human activities of storytelling and complex moral decision-making have a deep connection? What are the moral responsibilities of the artist, critic, and reader? What can religious perspectives—from Catholic to Protestant to Mormon—contribute to literary criticism? Thirty well known contributors reflect on these questions, including iterary theorists Marshall Gregory, James Phelan, (...) and Wayne Booth; philosophers Martha Nussbaum, Richard Hart, and Nina Rosenstand; and authors John Updike, Charles Johnson, Flannery O'Connor, and Bernard Malamud. Divided into four sections, with introductory matter and questions for discussion, this accessible anthology represents the most crucial work today exploring the interdisciplinary connections between literature, religion and philosophy.

Hume ist ein Vertreter der Moral-Sense-Schule der Ethik. Unter Tugend versteht er die Disposition zu tugendhaftem, d. h. selbstlosem Handeln. Der positive Wert tugendhaften Handelns besteht in seinem Nutzen, sei es für das Wohlergehen der betroffenen Individuen, sei es für die Gesellschaft als ganze durch die Stabilisierung ihrer institutionellen Ordnung. Dieser Doppelfunktion entsprechend, unterscheidet Hume zwischen den natürlichen Tugenden des Wohlwollens und den künstlichen Tugenden der Gerechtigkeit. Hume glaubte, den Hobbes zugeschriebenen Egoismus widerlegen zu müssen: Aus der überwältigenden empirischen Evidenz, (...) dass es tugendhafte Handlungen gibt, folgerte er, dass eine Art fundamentaler Sympathie für unsere Mitmenschen Teil der menschlichen Natur ist und dass der Egoismus daher falsch ist. Tatsächlich aber wird der von Hobbes vertretene Egoismus durch Humes Nützlichkeitserklärung der sozialen Tugenden nicht widerlegt, sondern bestätigt. (shrink)

The important recent book by Schurz ( 2019 ) appreciates that the no-free-lunch theorems (NFL) have major implications for the problem of (meta) induction. Here I review the NFL theorems, emphasizing that they do not only concern the case where there is a uniform prior—they prove that there are “as many priors” (loosely speaking) for which any induction algorithm _A_ out-generalizes some induction algorithm _B_ as vice-versa. Importantly though, in addition to the NFL theorems, there are many _free lunch_ theorems. (...) In particular, the NFL theorems can only be used to compare the expected performance of an induction algorithm _A_, considered in isolation, with the expected performance of an induction algorithm _B_, considered in isolation. There is a rich set of free lunches which instead concern the statistical _correlations_ among the generalization errors of induction algorithms. As I describe, the meta-induction algorithms that Schurz advocates as a “solution to Hume’s problem” are simply examples of such a free lunch based on correlations among the generalization errors of induction algorithms. I end by pointing out that the prior that Schurz advocates, which is uniform over bit frequencies rather than bit patterns, is contradicted by thousands of experiments in statistical physics and by the great success of the maximum entropy procedure in inductive inference.

Everything red is colored, and all squares are polygons. A square is distinguished from other polygons by being four-sided, equilateral, and equiangular. What distinguishes red things from other colored things? This has been understood as a conceptual rather than scientific question. Theories of wavelengths and reflectance and sensory processing are not considered. Given just our ordinary understanding of color, it seems that what differentiates red from other colors is only redness itself. The Cambridge logician W. E. Johnson introduced the terms (...) determinate and determinable to apply to examples such as red and colored. Chapter XI, of Johnson's Logic, Part I (1921), “The Determinate and the Determinable,” is the main text for discussion of this distinction. (shrink)

Myles Brand and Marshall Swain advocate the principle that if A is the set of conditions individually necessary and jointly sufficient for the occurrence of B, then if C is a set of conditions individually necessary for the occurrence of B, every member of C is a member of A. I agree with John Barker and Risto Hilpinen who each argue that this principle is not true for causal necessity and sufficiency, but I disagree with their claim that it is (...) true for logical necessity and sufficiency. The original appeal of the principle may be due to confusing two kinds of totality: to say that when every member of set A obtains, then every condition necessary for E obtains is not to say that every condition necessary for E is a member of A. All the authors mentioned believe that causal necessity precludes logical necessity. I deny this on the basis of an example from kinematics. Hume has not refuted definitions of causation in terms of logically necessary and sufficient conditions, nor have Brand and Swain. (shrink)

This paper presents a new argument for the likelihood ratio measure of confirmation by showing that one of the adequacy criteria used in another argument can be replaced by a more plausible and better supported criterion which is a special case of the weak likelihood principle. This new argument is also used to show that the likelihood ratio measure is to be preferred to a measure that has recently received support in the literature.

This book goes beyond historical and psychological explanations of the Holocaust to directly address the moral responsibility of individuals involved in it. While defending the view that individuals caught up in large-scale historical events like the Holocaust are still responsible for their choices, he provides the philosophical tools needed to assess the responsibility, both negative and positive, of perpetrators, accomplices, bystanders, victims, helpers and rescuers. This book will be an important addition to courses on the Holocaust in social and political (...) philosophy, history, religion, and applied ethics. (shrink)

This is the first of two papers that use off-training set (OTS) error to investigate the assumption-free relationship between learning algorithms. This first paper discusses the senses in which there are no a priori distinctions between learning algorithms. (The second paper discusses the senses in which there are such distinctions.) In this first paper it is shown, loosely speaking, that for any two algorithms A and B, there are “as many” targets (or priors over targets) for which A has lower (...) expected OTS error than B as vice versa, for loss functions like zero-one loss. In particular, this is true if A is cross-validation and B is “anti-cross-validation” (choose the learning algorithm with largest cross-validation error). This paper ends with a discussion of the implications of these results for computational learning theory. It is shown that one cannot say: if empirical misclassification rate is low, the Vapnik-Chervonenkis dimension of your generalizer is small, and the training set is large, then with high probability your OTS error is small. Other implications for “membership queries” algorithms and “punting” algorithms are also discussed. (shrink)

A quarter of a century ago, the first systematic behavioral experiments were performed to clarify the nature of color constancy—the effect whereby the perceived color of a surface remains constant despite changes in the spectrum of the illumination. At about the same time, new models of color constancy appeared, along with physiological data on cortical mechanisms and photographic colorimetric measurements of natural scenes. Since then, as this review shows, there have been many advances. The theoretical requirements for constancy have been (...) better delineated and the range of experimental techniques has been greatly expanded; novel invariant properties of images and a variety of neural mechanisms have been identified; and increasing recognition has been given to the relevance of natural surfaces and scenes as laboratory stimuli. Even so, there remain many theoretical and experimental challenges, not least to develop an account of color constancy that goes beyond deterministic and relatively simple laboratory stimuli and instead deals with the intrinsically variable nature of surfaces and illuminations present in the natural world.

Unger claims that we can block sorites arguments for the conclusion that there are no ordinary things only by invoking some kind of miracle, but no such miracle is needed if we reject the principle that every statement has a truth value. Wheeler's argument for the nonexistence of ordinary things depends on the assumptions that if ordinary things exist, they comprise real kinds, and that if ordinary predicates really apply to things, the predicates refer to real properties. If we accept (...) Wheeler's criteria for the reality of kinds and properties, we have no good reason to accept these assumptions. (shrink)

I have been a Daniel Callahan reader for over thirty years. My first published review was of Abortion: Law, Choice, and Morality. Callahan's latest book, The Five Horsemen of the Modern World: Climate, Food, Water, Disease, and Obesity, is a sustained and detailed explanation of a series of challenges facing humankind in this century. Callahan's prognosis is bleak, his analyses credible, and while hope is not lost, the moral of the story is that we had better get our act together (...) fast. Callahan argues that when we face challenges like these, rational persuasion is insufficient. Human emotions must be engaged. Without knowledgeable emotional engagement by millions of people, we are done for. It seems to me that he is really calling for a national cultural conversion experience, rather as, almost three hundred years ago, Jonathan Edwards declared that if there is a hell, it makes good sense to frighten people out of it!

According to John A Barker, whether an argument begs the question is purely a matter of logical form. According to me, it is also a matter of epistemic conditions; some arguments which beg the question in some contexts need not beg the question in every context. I point out difficulties in Barker's treatment and defend my own views against some of his criticisms. In the concluding section, "Alleged difficulties with disjunctive syllogism," I defend the validity of disjunctive syllogism against the (...) views of Alan Ross Anderson and Nuel D Belnap, Jr., ask pointed questions about the notion of intensional disjunction, and suggest how my treatment of begging the question can be extended to deal with the so-called paradoxes of strict implication.

In the form of inference known as inference to the best explanation there are various ways to characterise what is meant by the best explanation. This paper considers a number of such characterisations including several based on confirmation measures and several based on coherence measures. The goal is to find a measure which adequately captures what is meant by 'best' and which also yields the truth with a high degree of probability. Computer simulations are used to show that the overlap (...) coherence measure achieves this goal, enabling the true explanation to be identified almost as often as an approach which simply selects the most probable explanation. Further advantages to this approach are also considered in the case where there is uncertainty in the prior probability distribution. (shrink)

The measurement of force is based on a formal law of additivity, which characterizes the effects of two or more configurations on the equilibrium of a material point. The representing vectors (resultant forces) are additive over configurations. The existence of a tight interrelation between the force vector and the geometric space, in which motion is described, depends on observations of partial (directional) equilibria; an axiomatization of this interrelation yields a proof of part two of Newton's second law of motion. The (...) present results (which were derived from a curious and deep isomorphism between force measurement and trichromatic color measurement) yield a kind of subunit, which needs to be incorporated into more complete axiomatizations of mechanics that would fulfill the Mach-Kirchhoff program.

Naive mereology studies ordinary conceptions of part and whole. Parts, unlike portions, have objective boundaries and many things, such as dances and sermons have temporal parts. In order to deal with Mark Heller's claim that temporal parts "are ontologically no more or less basic than the wholes that they compose," we retell the story of Laplace's Genius, here named "Swifty." Although Swifty processes lots of information very quickly, his conceptual repertoire need not extend beyond fundamental physics. So we attempt to (...) follow Swifty's progress in the acquisition of ordinary concepts such as 'table'. (Puzzles of precision and intrusion appear along the way.) Swifty has to understand what tables are before understanding what temporal portions of tables are. This is one reason for regarding tables as ontologically prior to table portions. intrusion appear along the way.). (shrink)

Taking a schizoanalytic approach to audio-visual images, this article explores some of the radical potentia for deterritorialisation found within David Fincher's Fight Club (1999). The film's potential for deterritorialisation is initially located in an exploration of the film's form and content, which appear designed to interrogate and transcend a series of false binaries between mind and body, inside and outside, male and female. Paying attention to the construction of photorealistic digital spaces and composited images, we examine the actual (and (...) possible) ways viewers relate to the film, both during and after screenings. Recognising the film as an affective force performing within our world, we also investigate some of the real-world effects the film catalysed. Finally, we propose that schizoanalysis, when applied to a Hollywood film, suggests that Deleuze underestimated the deterritorialising potential of contemporary, special effects-driven cinema. If schizoanalysis has thus been reterritorialised by mainstream products, we argue that new, ‘post-Deleuzian’ lines of flight are required to disrupt this ‘de-re-territorialisation’. (shrink)

I propose a qualitative Bayesian account of explanatory goodness that is analogous to the Bayesian account of incremental confirmation. This is achieved by means of a complexity criterion according to which an explanation h is good if the reduction in the complexity of the explanandum e brought about by h (the explanatory gain) is greater than the additional complexity introduced by h in the context of e (the explanatory cost). To illustrate the account, I apply it in the context of (...) ad hoc hypotheses. (shrink)

I revise J L Mackie's first account of casual direction by replacing his notion of "fixity" by a newly defined notion of "sufficing" that is designed to accommodate indeterminism. Keeping Mackie's distinction between casual order and casual direction, I then consider another revision that replaces "fixity" with "one-way conditionship". In response to the charge that all such accounts of casual priority beg the question by making an unjustified appeal to temporal priority, i maintain that one-way conditionship explains rather that assumes (...) objective temporal dependence as well as objective casual dependence.

My primary aim in this paper is to show that the structure of experience must include a subject (or self). I argue that the subjectless (No-Self) views of our experience must be rejected, primarily because without the consciousness-unifying function of a subject they are unable to account for the unities of consciousness present in our experience. In addition, I contend that such views fail in another respect. They emphasize the streaming of experience, the ever-changing flow of conscious events, but have (...) difficulty identifying what must stand unmoving to provide the contrast needed for the experience of motion.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:War, Peace, and Reconciliation: A Theological Inquiry by Theodore R. WeberDavid H. MessnerWar, Peace, and Reconciliation: A Theological Inquiry Theodore R. Weber EUGENE, OR: WIPF & STOCK, 2015. 182 pp. $23.00Weber's book makes a helpful contribution to enlivening more theologically grounded strategies for peacemaking through reconciliation. It is a careful, systematic work that takes as its foundation a distinctively Christian view of [End Page 214] God's nature and (...) relation to the world. As a scholar and a pastor for over fifty years, Weber brings a much-needed, wise, and re-centered view to the questions entangled in war, peace, and reconciliation. He advises us not to look first into the realities of war for God, but to look to understand God as the context for all human conflict. He forcefully calls the reader to be a reconciler despite the intractability of conflict. The book is structured in three main parts, beginning with the theological context, then the political context, and, last, to peace, justice, and the church.The "war" that Weber addresses is interstate conflict, representing the negation of the web of relationships constituting a healthy international system. War disrupts God's plan and ruptures the right relationship between humanity and God (43–44). Throughout, Weber embraces a kind of Christian Realism, one that takes seriously the loving nature of God, the sinfulness of humanity, and the limits and possibilities for peacemaking in a human world. Downplaying the pacifistic message of Jesus, Weber highlights the necessities within a fallen world. We cannot eliminate war as a category of existence under the conditions of sin (until the eschaton), but with right orientation and action we can eliminate some war.Noting inadequacies of the just war tradition (though not dispensing with it), Weber identifies the need to ground it more firmly in theology, including enhanced attention to "just intention" as a primary criterion in evaluating the prosecution of war, displacing cause as the first question with which we must interrogate ourselves. Discernment about war and peace must be an ongoing conversation that should include people of faith as well as policymakers. Weber's theological and pastoral sensibilities, alongside his political savvy throughout, make the book a pleasurable and provocative read.The definition of reconciliation deployed is broad and complex, and Weber marshals it for powerful work. Reconciliation "is God's work—the movement of Divine grace through history, engaging all aspects of brokenness and promise and reaching its climax of fulfillment and disclosure in the life, death, and resurrection of Jesus Christ" (3). Grace continually calls humanity to enter into the work of reconciliation. Here Weber introduces the idea of relational power; more nuanced than mere substantive power, it connects to the core idea of institution building and the critical emphasis on strengthening the social fabric in the interest of peace. It is the hallmark of the reconciling transformation from systems of dominance to relationships of consent.The book raises questions regarding how to put reconciliation as described into concrete practice, responding to real cases and controversies. Also, there could be added discussion, against this theological backdrop, of what opportunities exist amid current US and global regime change to enter this reconciling activity more fully.Ultimately, the Christian context is central to understanding the ethics that Weber advances. Weber recommends a biblical foundation, one in which [End Page 215] we take the benefit of reading scripture backward from the Christ event. Such an exegetical strategy reveals that God has a plan for all of humanity, a vision of inclusiveness and reconciliation. It is from this vantage point of God's culminating vision, Weber illuminates, that we can understand and embrace human action throughout history and the meaningful, if incomplete, work of reconciliation to which we must commit ourselves, both politically and spiritually.
