We address the need for a model by considering two competing theories regarding the origin of life: (i) the Metabolism First theory, and (ii) the RNA World theory. We discuss two interrelated points, namely: (i) Models are valuable tools for understanding both the processes and intricacies of origin-of-life issues, and (ii) Insights from models also help us to evaluate the core objection to origin-of-life theories, called “the inefficiency objection”, which is commonly raised by proponents of both the Metabolism First theory (...) and the RNA World theory against each other. We use Simpson’s Paradox (SP) as a tool for challenging this objection. We will use models in various senses, ranging from taking them as representations of reality to treating them as theories/accounts that provide heuristics for probing reality. In this paper, we will frequently use models and theories interchangeably. Additionally, we investigate Conway’s Game of Life and contrast it with our SP-based approach to emergence-of-life issues. Finally, we discuss some of the consequences of our view. A scientific model is testable in three senses: (i) a logical sense, (ii) a nomological sense, and (iii) a current technological sense. The SP-based model is testable in the first two senses but it is not feasible to test it using current technology. (shrink)

Reasoning about situations we take to be impossible is useful for a variety of theoretical purposes. Furthermore, using a device of impossible worlds when reasoning about the impossible is useful in the same sorts of ways that the device of possible worlds is useful when reasoning about the possible. This paper discusses some of the uses of impossible worlds and argues that commitment to them can and should be had without great metaphysical or logical cost. The paper then provides an (...) account of reasoning with impossible worlds, by treating such reasoning as reasoning employing counterpossible conditionals, and provides a semantics for the proposed treatment.

This article focuses on the main methods used in analytic metaphysics. It first considers five important sources of constraints on metaphysical theorizing: linguistic and conceptual analysis, consulting intuitions, employing the findings of science, respecting folk opinion, and applying theoretical virtues in metaphysical theory choice such as preferring simpler theories, or preferring more explanatory theories. It then examines the role of formal methods in metaphysics as well as the role of metaphysical communities, traditions, and the place of the history of metaphysics (...) in contemporary work. It also discusses the issue of whether metaphysics should be seen as an enterprise that will yield knowledge of metaphysical matters or whether it should have more modest epistemic goals. Finally, it explores the question of how much of metaphysics is a priori. (shrink)

After his father passed away, James Nolan's mother gave him a box of materials that his dad had kept private. To Nolan's complete surprise, the contents revealed the role his grandfather had played as a doctor in the Manhattan Project. Dr. Nolan, it turned out, had been a significant figure. A talented radiologist, he cared for the scientists on the Project, helped organize the safety and evacuation plans for the Trinity Test at Alamogordo, escorted the "Little Boy" (...) bomb from Los Alamos to Japan, and was one of the first Americans to enter the irradiated ruins of Hiroshima and Nagasaki. The documents set Nolan on a hunt for more information about his grandfather and more generally about the conflicted role that medical personnel played in the early years of atomic testing. The result is a compelling history of the dawn of the atomic age as seen through the eyes of men and women torn between their duty and desire to win the war and their oath to protect life. Nolan follows his grandfather and medical colleagues as they seek to maximize safety while serving leaders determined to minimize delays, and as they consider the ethics of ending the deadliest of all wars with the most lethal of all weapons. The result, Nolan shows, was a very human pattern of caution, co-optation, and complicity. A vital and vivid account of a largely unknown chapter in atomic history, Delivering Little Boy is also a profound meditation on the professional and moral dilemmas that ordinary people face in extraordinary times.

A lot of philosophers engage in debates about what claims are “metaphysically necessary”, and a lot more assume with little argument that some classes of claims have the status of “metaphysical necessity”. I think we can usefully replace questions about metaphysical necessity with five other questions which each capture some of what people may have had in mind when talking about metaphysical necessity. This paper explains these five other questions, and then discusses the question “how much of metaphysics is metaphysically (...) necessary?”, and each of its five replacements. (shrink)

This paper responds to commentaries by Kaiserman and Magidor, and Hawthorne. The case of the infinite clowns can teach us several things.

It is almost universally believed that some infinite regresses are vicious, and also almost universally believed that some are benign. In this paper I argue that regresses can be vicious for several different sorts of reasons. Furthermore, I claim that some intuitively vicious regresses do not suffer from any of the particular aetiologies that guarantee viciousness to regresses, but are nevertheless so on the basis of considerations of parsimony. The difference between some apparently benign and some apparently vicious regresses, then, (...) turns out to be a matter of a more general assessment of costs and benefits, making viciousness of regresses in some cases less of a local matter than is usually thought.

Thought experiments are common where infinitely many entities acting in concert give rise to strange results. Some of these cases, however, can be generalized to yield almost omnipotent systems from limited materials. This paper discusses one of these cases, bringing out one aspect of what seems so troubling about "New Zeno" cases. -/- This paper is in memory of Josh Parsons.

Methodological naturalism arises as a topic in metaethics in two ways. One is the issue of whether we should be methodological naturalists when doing our moral theorising, and another is whether we should take a naturalistic approach to metaethics itself. Interestingly, these can come apart, and some naturalist programs in metaethics justify a non-scientific approach to our moral theorising. This paper discusses the range of approaches that fall under the general umbrella of methodological naturalism, and how naturalists view the role (...) of science in ethics and metaethics. It discusses how naturalism interacts with the use of intuitions, using conceptual analysis, and reflective equilibrium methods. Finally, it discusses some ways using scientific investigation can make distinctive contributions to ethics and metaethics. (shrink)

This paper makes a case that we should believe in the existence of worldly states of affairs.

Zurvanism was an ancient variant of Zoroastrianism. According to Zurvanism, the great powers of good and evil, Ahura Mazda and Angra Mainyu, were the sons of a greater god Zurvan, associated with time. According to Eudemus of Rhodes, some Persian thinkers, presumably Zurvanists, took there to be three great principles underlying the world: light, darkness, and greatest of all time (or perhaps, according to Eudemus, space). This paper explores what metaphysics might underlie these doctrines, and what contemporary options we have (...) for making sense of a metaphysics where time is the ultimate principle. Among the options explored is the option that despite appearance many of the entities of the concrete world are identical to stretches of time, or are somehow aspects of stretches of time; that they include times as parts, or are included in times as parts; that they are somehow properties of time; or hylomorphic compounds of which time is the matter; that the world is somehow a mixture of time, light, and dark; or that somehow the ends or teloi of everyday objects and processes are to be found among good, evil, and time.

Fourteen newly commissioned essays trace the historical development of the distinction between primary and secondary qualities, which lies at the intersection of issues in metaphysics, epistemology, and philosophy of perception. 'Primary and Secondary Qualities' focuses on the age of the Scientific Revolution, the 'locus classicus' of the distinction, but begins with chapters on ancient Greek and Scholastic accounts of qualities in an effort to identify its origins. The remainder of the volume is devoted to philosophical reflections on qualities from the (...) seventeenth century to the present day. Virtualliy every major figure is represented from Gassendi to Kant, and special attention is paid to Locke, Descartes, and Hume. The essays collected here cover a wide range of topics, including the foundation for the distinction, the question of whether it is lmetaphysical or merely epistemic, the status of secondary qualities, the nature of sensoriy representation, the relation between philosophy and science, the status of dispositions, and the semantics of sensible-quality terms"--Publisher's description, p.

Possible worlds have found many applications in contemporary philosophy: from theories of possibility and necessity, to accounts of conditionals, to theories of mental and linguistic content, to understanding supervenience relationships, to theories of properties and propositions, among many other applications. Almost as soon as possible worlds started to be used in formal theories in logic, philosophy of language, philosophy of mind, metaphysics, and elsewhere, theorists started to wonder whether impossible worlds should be postulated as well. In many applications, possible worlds (...) face limitations that can be dealt with through postulating impossible worlds as well. This chapter examines some of the uses of impossible worlds, and philosophical challenges theories of impossible worlds face. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Christ's Human Nature and the Cry from the Cross:St. Thomas Aquinas on Psalm 22:2Philip Nolan O.P.Christ's cry from the Cross quoting Psalm 22 (Mark 15:34; Matt 27:46) has become a central focus for contemporary Christological debates.1 A number of modern thinkers have read this verse as expressing in Christ an experience of dereliction incompatible with traditional positions concerning divine impassibility Christ's beatific knowledge, and Trinitarian relations.2 Thomas Joseph (...) White has recently offered an insightful Thomistic critique of these interpretations: [End Page 1219]The final cry of Christ on the cross cannot be interpreted as a cry of either despair or of spiritual separation from God. By contrast, it must be understood theologically as a prayer of desire related to Christ's abandonment to the Father and his hope to introduce humanity into the eschatological gift of redemption.3In his work, White is concerned to engage with modern Christological themes using principles derived from the Thomistic tradition. For this reason, he articulates a rather original alternative to modern theologies of dereliction—especially those marked by divine kenoticism and Luther's theology of the Cross. In offering a view inspired by Thomistic principles, White presents his own creative retrieval of Aquinas's ideas concerning the cry from the Cross.At times, however, White's argument leaves somewhat obscure the literal meaning of the words of that cry: "My God, my God, why have you abandoned me?"4 For example, in pushing back against radical interpretations [End Page 1220] of dereliction, he shifts the language of "abandonment" from God's abandonment of Christ to Christ's abandonment to the Father. My argument in this article is that the textual commentaries on Psalm 225 by Augustine and Aquinas—material that White does not consider specifically—can provide an alternate and somewhat complementary Thomistic approach to the one White proposes, and one more soundly based on Aquinas's texts themselves.6 Christ's cry is a quote from this psalm, and Aquinas's commentary on Ps 22:27 develops the Augustinian interpretation of this verse in order to give greater emphasis to Christ's human nature. This emphasis helps to explain, in a classical way, what it can mean that Christ is abandoned. Thus, Aquinas's exegesis bolsters the orthodox response to contemporary revisionist theologians by providing a clear literal understanding of this contested biblical passage without applying an experience of damnation to Christ or denying classical positions concerning divine impassibility, Christ's beatific knowledge, and the nature of Trinitarian relations.To make this argument, I will first look at the rich tradition of reflection on the Christological meaning of the Psalms, and Psalm 22 in particular, inherited by Thomas. This tradition includes a series of psalm commentaries, conciliar documents, and a variety of other theological works. In this tradition, I argue, we see two primary interpretative approaches. The first is what I will call the Augustinian approach, which insists that Christ is speaking on the Cross for sinners and in the voice of sinners. The second interpretation places more weight on Christ's own voice and insists that he is speaking in a real way for himself—Christ in some way truly is abandoned by God. These interpretations need not and should not be read as contradictory. In fact, all the authorities I examine insist on the first approach. Differences emerge, however, in how they coordinate the latter interpretation with the former. I will discuss Thomas's synthesis of these interpretations, a synthesis that he grounds in the reality of Christ's human nature. Finally, I will suggest [End Page 1221] how a close reading of Thomas's mature treatment of Ps 22:2 supplements contemporary Thomist responses to modern Christological concerns and misguided interpretations of Christ's cry on the Cross.Thomas's Sources for Reading Psalm 22:2Thomas's primary source for understanding Ps 22:2 is Scripture itself Both Mark and Matthew report that Christ spoke the words of this psalm from the Cross, a fact which necessitates for Thomas a Christological interpretation of the psalm.8 Augustine links Ps 22:2 with passages in...

The cognition and information theoretic sciences have now been in existence for the better part of a century. In that time, their varied disciplines have undergone extensive maturation, honing their methods, constitutions, and evaluation techniques in the pursuit of academic rigor, while not losing sight of the practical influences that have served as their almost universal cornerstone. Meanwhile, this period has also been marked by increasing disparity and gradual distancing of the philosophical underpinnings upon which each field is founded, adding (...) strain to interdisciplinary collaborative efforts. This article presents an overview of select information-science-related cognition disciplines, and shows how the nascent Philosophy of Information can be adopted as a means of unifying these philosophical foundations in an empirically sound manner, without sacrificing general applicability. In addition, it demonstrates how PI is already rooted in the philosophies or epistemological views of several of the cognition disciplines, implicitly or otherwise. (shrink)

This book sets stories of morally decent actions in a wider context of the essential barbarism of war. It charts the wider path of obscenity and atrocity in war to highlight moments of moral grace, of goodwill toward the enemy and civilians inside a frame of jarring ugliness and malice. It does not seek traditional war heroes or elevate anyone to secular sainthood. It presents ordinary people caught up in the extraordinary swirl of war, who did not see themselves as (...) saints or heroes at the time yet showed rare courage, notwithstanding. It presents portraits of everyday folk who reacted in a moment of crisis with mercy and sensitivity, with empathy for shared humanity with an enemy or the innocent. The goal is to recognize those brave few who refused immoral acts and orders, even at grave personal risk. Who in the midst of degradation and dehumanization saw common humanity, then chose not to pull the trigger. And others who put themselves outside suffocating conformity, to help rather than kill a wounded enemy or stop an atrocity. And those who made a simple gesture of kindness to a suffering enemy that had no larger consequence. Uninterested in saints, it looks to map a more modest, achievable and relatable lesson taken from the annals of war: an accounting best captured in a simple yet compelling word 'decency.'. (shrink)

As is well known, Aristotelian natural philosophy, and many other systems of natural philosophy since, have relied heavily on teleology and teleological causation. Somehow, the purpose or end of an obj ect can be used to predict and explain what that object does: once you know that the end of an acorn is to become an oak, and a few things about what sorts of circumstances are conducive to the attainment of this end, you can predict a lot about the (...) sprouting of the acorn and the subsequent behaviour of the piece of vegetation that results. Once you know that a rock seeks to move towards the centre of the Earth, you gain some insight into why it falls when released, and why it deforms the carpet or foot that it lands on. Once you know that the rabbit seeks to preserve itself, you can predict it will run from the fox. And so on. There are at least three features of Aristotle’s teleology, and more generally of an Aristotelian frame of mind about teleology, that may induce suspicion. One is that an end can serve as a "cause": as well as the sort of causation we all recognize, efficient causation, there are other forms, one of which is teleological causation. However, this can look less odd if we think of causes as things that figure in "because" answers to "why" questions. Whether or not self-preservation, or the rabbit’s continued existence, or something similar, causes the rabbit to run, the reply "because it seeks to continue in existence" certainly makes sense as an answer, or part of an answer, to a question about why it ran from the fox.

Despite its growing use over past decades, there has been relatively little public or scholarly discussion of life sentences that deny the possibility of parole. This essay outlines the labyrinthine legal and political developments that have rendered life imprisonment difficult to address—including the intertwined histories of the death penalty and civil death—and draws upon the life writing of those serving life to theorize a more distinct understanding of this punishment. Witnesses reveal how the possibility of life despite the impossibility of (...) parole punishes by subverting the goals of human growth and development. The potentiality of what can be done in the present grinds up against the futility of what could have been done and what could be done were release an option. Considered alongside the laws and court opinions and claims that characterize its convoluted development, these testimonies reveal this punishment’s role in the American imagination. Life without the possibility of parole reinforces and relies upon a vision that not simply some people are unable to change, but that anyone in a democracy—no matter their position—is some steps away from irretrievable exclusion. Permanent confinement denies a restorative vision of democracy: any effort to abolish or amend it must include the voices of those imprisoned. (shrink)

What political problem can autobiography solve? This article examines the politics of Frederick Douglass’s antebellum personal narratives: his 1845 slave narrative, the Narrative of the Life of Frederick Douglass, an American Slave, and his 1855 autobiography, My Bondage and My Freedom, written at the opposite ends of Douglass’s transition from the abolitionist politics of William Lloyd Garrison and Wendell Phillips to Douglass’s defense of political action and the Constitution as anti-slavery. Placing the two texts alongside Douglass’s distinction “to narrate wrongs” (...) and “denouncing them,” I argue that Douglass writes My Bondage and My Freedom as a mode of denunciation: an autobiographical critique of injustice that balances analysis of collective oppression with advocacy for communal emancipation. Whereas to narrate wrongs encouraged readers to judge Douglass’s story alongside popular criteria of justice, to denounce wrongs is to implicate readers within the structures that create antebellum subjects on and off the plantation, by revealing the coercions and conditionings of society that make not simply slaves but slaveowners, sympathizers, and abolitionists. This article claims that autobiography is a distinct genre of political theory, one that challenges present relations between the individual and the collective by representing not simply its author but an expanded view of “the people.”.

RULE or restricted utilitarianism is frequently propounded and just as frequently criticized in the literature. Its various refinements initially involve conceptual adjustments such as clarifying the logical relations between some stateable rule of utility and other moral rules or the specification of a criterion for ranking rules in case of conflict and so forth. It soon becomes clear, comparatively speaking, that a cluster of problems involving justice, personal rights and the denotation of ‘intrinsic good’ cannot be resolved without extending rule (...) utilitarianism as a theory of right conduct and justification; thus the origin of the appellation ‘extended’ rule utilitarianism. In this paper I shall: render an interpreted model of rule utilitarianism that possesses all the logical features of alternative interpretations. Describe a style of argument for extending rule utilitarianism to incorporate a rule of distribution. Such an extension preserves the consistency of rule utilitarianism. Describe a second style of argument for extending rule utilitarianism to incorporate a rule of distribution. Such an extension does not preserve the consistency of rule utilitarianism. (shrink)

An overview of hyperintensionality is provided. Hyperintensional languages have expressions with meanings that are more fine-grained than necessary equivalence. That is, the expressions may necessarily co-apply and yet be distinct in meaning. Adequately accounting for theories cast in hyperintensional languages is important in the philosophy of language; the philosophy of mind; metaphysics; and elsewhere.

In recent years a strand of thinking has developed in private law scholarship which has come to be known as 'rights' or 'rights-based' analysis. Rights analysis seeks to develop an understanding of private law obligations that is driven, primarily or exclusively, by the recognition of the rights we have against each other, rather than by other influences on private law, such as the pursuit of community welfare goals. Notions of rights are also assuming greater importance in private law in other (...) respects. Human rights instruments are having an increasing influence on private law doctrines. And in the law of unjust enrichment, an important debate has recently begun on the relationship between restitution of rights and restitution of value. This collection is a significant contribution to debate about the role of rights in private law. It includes essays by leading private law scholars addressing fundamental questions about the role of rights in private law as a whole and within particular areas of private law. The collection includes contributions by advocates and critics of rights-based approaches and provides a thorough and balanced analysis of the relationship between rights and private law. (shrink)

Liberals agree that free speech should be protected, where speech is understood broadly to include all forms of intentional communication, including actions and pictures, not merely the spoken or written word. A surprising view about free speech in some liberal and legal circles is that communications should be protected on free-speech grounds only if the communications are mentally mediated. By “mentally mediated communication” we mean speech which communicates its message in such a way that the message can be rationally evaluated (...) by hearers, and causes the hearers to believe it, when it does, through the mechanism of those hearers employing their rational capacity to judge that it is correct. The mental-mediation or persuasion principle, as it is sometimes called, has some important legal and public policy implications. It has been applied to argue that certain forms of expression, despite being forms of speech or expression, lack even a prima facie claim to protection on free speech grounds. -/- Our central aim is to show why the mental mediation principle is mistaken. Liberals should think that some speech which is not mentally mediated deserves protection for the very same reasons that speech which is mentally mediated is often thought to deserve protection.
