The paper analyses the place of the End in Mary Shelley’s 1826 science fiction novel The Last Man, in which the image of a world devoid of humanity, as portrayed by the last man writing the last book, is drawn before the reader through a conceptual rethinking of notions such as the loss of the world, prophecy of the future, and oblivion of the past, as well as the return of the irretrievable through the siren song.

This article explores the differences and similarities between China and the West in terms of history.While the term itself is of ancient Greek origin, the "semantic field" of history resonates in many ways with the semantic field covered by the word hi in China. The original Greek usage, derived from Herodotus, means an inquiry into human affairs. The inquiry involved narrative over large stretches of time and space, but many of its main concerns were metahistorical in terms of nineteenth-century western (...) historicism. This is true of Thucydides and later even of Machiavelli. History was a casebook and a "mirror" of metahistorical experiences which could be used in an entirely unhistorical way to shed light on many areas of human ethical, political, and other modes of thought and behavior.The nineteenth-century western "historicist" view of history as a "master narrative" reflecting an irreversible, inexorable process of development shaping the entire destiny of the human race may have some of its roots in the Heilsgeschichte of the Hebrew Bible, particularly in its "progressivist" version. Historicism also implied that human beings were basically formed by their loci within their historical epoch and raised serious questions concerning the role of human agency in human affairs.In China--in contrast to the West--we find particularly in the Confucian stream of thought the early emergence of the idea of a metahistorical ideal order which had been realized within the human sphere in the past. Here the historical problem was the fatal human capacity to fall away from the principles of this normative order . The problem became: why does humanity depart from the good order and to what extent can it be restored?Despite the vastly different framework, we can find in China both the kind of "unhistorical" history which regards history as a reservoir of metahistorical experience in ethical, political, and other aspects of life, and a view which projects something like the image of an inexorable and impersonal historical process involving both the flourishing and decline of the normative order. Within the latter framework we find some dilemmas concerning the role of human agency that we find in post-Enlightenment, western "master narratives.". (shrink)

Heidegger’s philosophy has been interpreted as an absolute historicism, unable to point to a unhistorical standpoint from which history can be judged upon. K. Löwith, for instance, has indicated that the cause of this difficulty is to be found in the conception of time: whereas, in Greek thought, time was considered only as a manifestation of the essence, in modern thought time has the tendency to become the essence itself, as that which fulfills itself in time, up to Heidegger’s identification (...) of being and event. What is interesting in my critique is that the conception of time is strictly interwoven with a specific way of conceiving justice and, broadly speaking, ethics. In Plato’s philosophy, justice as measure corresponds to a cyclical and even retrogressive conception of time, the one enounced in the myth of Chronos, in the Politikos. The modern conception of time, spiritualistic and biologistic, is instead cyclical and irreversible, cumulative: its most significant expression is Hegelianism. The existential conception of time, instead, is neither cyclical nor cumulative. By commenting on Heidegger’s Anaximander’s Saying, I wish to show the possibility of conceiving temporality as disjunction and only as such capable of producing justice – which I understand as a new possibility of meaning that does not exclude, but carries within itself, emancipation. An ethics of the present developed on the basis of this conception of time – which Heidegger has not completely endorsed – would then be an ethics which accepts as its own ground the discontinuous, yet inventive, dimension of time.

If recent cosmological reasonings are correct, our universe is expanding irreversibly into oblivion—a conclusion that might well inspire feelings of insignificance and futility. Can we perhaps find a sense of meaning by seeing ourselves as participants in intergalactic morality? In this paper I examine the way in which moral rules come into being, exist, and cease to exist—and conclude that there is an intergalactic morality in which we can participate and through which we can feel a sense of significance in (...) our rapidly dissipating universe.

In the age of ubiquitous technology, humans are reshaped through each transaction they are involved in. AI-driven networks, online games, and multisensory interactive environments make up alternate realities. Within such alternate worlds, users are reshaped as deterministic agents. Technology’s focus on reducing complexity leads to a human being dependent on prediction-driven machines and behaving like them. Meaning and information are disconnected. Existence is reduced to energy processes. The immense gain in efficiency translates as prosperity. Citizens of advanced economies, hurrying in (...) the rhythm of machine-driven interactions, feel entitled to it. Successful at the price of self-awareness, they no longer know what this means. Happiness and prosperity are not consubstantial. Lack of happiness leads to aggression. This is the image of the world as we see it, no longer looking at each other, eye to eye, but screen to screen. The questions eliminated in the process of transferring responsibility from the individual to machines will inevitably become society’s new focus. When the goal is to get everyone to behave like a machine, the Singularity hypothesis becomes self-fulfilling prophecy. If, in addition to having exhausted natural resources, society does not want to end up making the human mind superfluous, it has to seek a better understanding of what makes anticipation possible. As a definitory characteristic of the living, corresponding to its complexity, anticipation can no longer be taken for granted, while every effort is made to reduce complexity for efficiency’s sake. Awareness of the processes conducive to its expression in successful human action will position human beings as masters of their destiny, not slaves of their own making. Antecapere ergo sum might be the counterclaim to Descartes’ Dubito ergo sum . To resist being perfected into oblivion, that is, unsustainable prosperity, means to reclaim the knowledge corresponding to higher levels of complexity. (shrink)

Abū Bakr Muḥammad bin Zakariyya’ al-Rāzī (865–925) is generally known as a freethinker who argued against prophecy and revealed religion based on arguments from fairness of God and rationality. Recently some scholars argued that Razi was not as radical as the general interpretation takes him to be. Both the freethinker and conservative interpretations seem well supported based on difference bodies of evidence. However, the evidence is based on secondhand reports. In this paper I argue there is an interpretation of prophecy (...) which is supported by primary sources and can reconcile these putatively contradictory positions. Under my interpretation Razi allows for prophecy based on the rationality of moral deference in certain circumstances. In this picture one function of prophets is to act as moral experts for deference. This interpretation provides a synthesis of the freethinker and conservative views. Razi is conservative in having room for prophecy because of his dualist nature of humanity, and Razi is still a freethinker who values reason above all, because moral expertise requires excellent command of reason.

In Prophecy without Contempt, Cathleen Kaveny argues that prevailing scholarly approaches to religious and public discourse misunderstand the actual complexity of moral rhetoric in America. She endeavors to provide a better account through study of the role the Puritan jeremiad has played. Kaveny then offers a normative case for deliberative public moral discourse and the limited exercise of prophetic denunciation. I argue that Kaveny's distinction between deliberation and prophetic denunciation is overdrawn. They are ideal types that elide other rhetorical forms. (...) Moreover, both deliberative discourse and prophetic denunciation assume a social contract or shared tradition. Healthy moral discourse requires revolutionary rhetoric to interrogate and break traditions that are themselves morally compromised. (shrink)

In this contribution, I discuss some less well-known premodern and early modern antecedents of Spinoza’s concepts and claims in the _Tractatus Theologico-Politicus_. On the one hand, I will argue, Spinoza’s notion of prophecy owes more to Moses Maimonides than to any Christian author; and through Maimonides, Spinoza may be linked to the discussion of prophecy in _The Virtuous City_ by the tenth-century Islamic philosopher al-Farabî. Spinoza’s concern with prophecy as a popular formulation of the Divine Law may be fruitfully seen (...) in the light of these two authors. On the other hand, Spinoza’s notion of _pietas_ has arguably been shaped by a number of early modern authors from the Low Countries, including Thomas a Kempis and Erasmus: it does not consist in merely obeying the law, but also has a clear devotional and theist dimension of love for God and for one’s neighbors. As such, it may be associated with recent ideas on philosophy and spiritual exercises. These findings have a number of non-trivial implications for Spinoza’s place in the rise of modern, academic Western philosophy. I will discuss these implications in the context of Pierre Hadot’s influential views on philosophy as a way of life and Michel Foucault’s notion of spirituality. (shrink)

Cathleen Kaveny's Prophecy Without Contempt seeks to reorient the conversation among religious ethicists and political theorists about religion in public life. Rather than focus on religious speech in general, Kaveny distinguishes deliberation and indictment as forms of discourse, and she subjects indictment to ethical evaluation. She aims to constrain the public exercise of inordinate indictment, while encouraging prophetic indictment that meets the demands of justice. While the book is a much-needed corrective, Kaveny's focus on the powerful rhetoric of prophetic indictment (...) omits the harms that can come to the body politic from unjust silence. Such silence deserves more moral attention. (shrink)

A good theory of rationality should accommodate debates over first principles, such as those of rationality. The modest challenge made in this article is that relativists try to explain the (intellectual) value of some debates about first principles (absolute presuppositions, basic assumptions, intellectual frameworks, intellectual commitments, and paradigms). Relativists claim to justify moving with relative ease from one framework to another, translating chunks of one into the other; this technique is essential for historians, anthropologists and others. Thus ideas concerning false (...) prophecy are transferable to contemporary discussions. Ancient false prophets offered illusions of overcoming difficult problems cheaply; relativists do that too. The problem that relativism purports to solve cheaply is that of legitimizing pluralism. As the absolutist theory of truth is intuitively problematic, relativism seems intuitively more acceptable, but this intuitive advantage vanishes when it manifests as false prophecy. (shrink)

While prophethood is the backbone of the Islamic tradition and an uncompromised tenet of faith, the impact of modernity with its ambivalent status afforded to the prophet and institution of prophethood shook many Muslim scholars. Through analysis of these modern debates on prophethood in Islam, this book situates Muhammad Iqbal's (1877-1938) and Said Nursi's (1877-1960) discourses within it and assesses their implications on the modern period. This book introduces the 'what, who and how' of the prophets in the Islamic tradition. (...) It unveils the rich Islamic literature of both the classical and modern periods and analyses the construction of their philosophies and theologies. Concise in both historical and textual analysis, this book makes an important contribution to our understanding of contemporary debates on prophecy and prophethood in Islam, and will be of great interest to postgraduate students and researchers of Islam, religious studies, medieval studies and contemporary studies of Islam and religion.

While virtually all of the few scholars who have dealt with the subject of prophecy in Origen of Alexandria have limited their analysis to Origen’s Contra Celsum, the present essay will take into consideration the most remarkable insights from all of Origen’s extant literary output, including his definitions of prophecy, which can significantly enrich our understanding of the value, sources, and functions of prophecy according to Origen. Fruitful comparisons with Philo, Clement, Eusebius, and Plotinus will also be drawn. What will (...) emerge from the present investigation is that, for Origen, prophets are moral examples, and true prophecy is a gift shared by men and women alike, is a kind of “proof,” structurally related to allegory and philosophy, and contains the announcement of Christ and, closely connected to this, the promise of the eviction of evil and the universal restoration or apokatastasis, which is a core doctrine in Origen’s philosophico-theological system.

In April 1996, two men working at a convalescent center wrote a letter to the journal Nature proposing that a new word be adopted to designate a person who is the last in the lineage: endling. This had come up because of patients who were dying and thought of themselves as the last of their family line. The word was not picked up in medical circles. But, in 2001, when the National Museum of Australia (NMA) opened its doors, it featured (...) a gallery called Tangled Destinies and endling reappeared. On the wall facing a case with a thylacine specimen was written: Endling (n.) The last surviving individual of a species of animal or plant. Since that appearance, the word endling has slowly seeped into popular culture, appearing in symphonic music, performance art, science fiction stories, comics, and other art works. This paper examines the cultural power of the concept of endling as the last of a species and the history of its mobilization in a world facing extinction around every corner. (shrink)

This article examines the role of Prophecy and divination in the success of the Lumpa Church of Alice Mulenga Lenshina in Zambia. Concurring with James Amanze, the article argues that the rapid growth of Christianity in Africa is to a large extent due to its engagement with prophecy and divination. Strong growth in African Christianity takes place mainly in the African Initiated Churches which are Pentecostal-charismatic in their outlook. In these Churches the emphasis is on the prophetic ministry of the (...) Church, evident in the performance of divination, healing and in predictions of the future. A good example is the Lumpa Church of Lenshina. Taking this Church as a case study, the article argues that Lenshina’s success and that of her Church are based on the fact that divination, prophecy and a search for gender justice were taken seriously.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Prophecy without Contempt: Religious Discourse in the Public Square by Cathleen KavenyKyle LambeletProphecy without Contempt: Religious Discourse in the Public Square Cathleen Kaveny CAMBRIDGE, MA: HARVARD UNIVERSITY PRESS, 2016. 464 PP. $49.95"The American public square is not a seminar room" (419). This being the case, Cathleen Kaveny's Prophecy without Contempt challenges ethicists, among others, to reconsider the rhetoric of moral address. Rather than a narrow focus on deliberation, (...) Kaveny commends attention to the genre of indictment, and particularly the American jeremiad, as a significant mode of moral address that deserves normative analysis. Kaveny is no partisan of prophecy. But she offers moral and rhetorical criteria of prophetic speech that allow the genre to do its indispensable work.Kaveny's book proceeds in four parts. In the first part she sets the stage for her argument by surveying three prominent accounts of the status of public moral discourse, critiquing each yet drafting them all into a more global [End Page 195] critique of the failure to take into account the central significance of the rhetoric of prophetic indictment. Correcting this neglect in the second part, Kaveny executes a historical retrieval of the American jeremiad, beginning with early Puritan preachers of the Massachusetts Bay Colony. The point of her at times plodding historical reconstruction is that the jeremiad was not originally socially divisive but rather served to build up the community by calling listeners back to a commonly agreed-on covenant. This uniting function of the jeremiad fails in later generations. Some readers will worry that Kaveny's retrieval risks nostalgia insofar as it conforms to a MacIntyrian declension narrative in which golden origins were irreplaceably fractured.This risk, however, is mitigated by the third and fourth parts of the book, in which Kaveny turns to constructive ethics. She argues that the forensic rhetoric of prophetic indictment should be understood as a chemotherapy. It should not be confused with deliberation, the normal form of moral address. Yet, like chemotherapy, used in the right amount it can restore an ailing patient to health. As we have come to expect, Kaveny is especially adept at taking the moral frameworks developed in one sphere and applying them to another. Trading medical analogies for military, Kaveny argues that best practices of ius bellum verborum can be developed from just war criteria. She adds to these rhetorical constraints that prophetic critique be offered against one's own people with whom one identifies through lamentation and hope. Kaveny concludes with advocacy of prophetic humility and irony as necessary elements of prophetic speech in our pluralistic contemporary context.Although written in accessible prose, Kaveny's book deserves rigorous scholarly engagement. She constructs her argument with the gracious interdisciplinarity of a leading scholar of law and theology at the height of her powers. She is methodologically promiscuous but never shallow, drawing on scholarly fields of moral philosophy, biblical studies, American religious history, in-depth case analysis of contemporary arguments about abortion and torture, and historical paradigms of prophetic virtue (and vice). While scholars in each of these fields will find claims worth engaging in Kaveny's text, ethicists will be particularly interested in her argument for a constrained, continuing need for prophetic indictment.My one critique is that her account of prophetic rhetoric is too conservative. Based on her historical retrieval, Kaveny argues that indictment should serve only to call listeners back to an already agreed-on covenant. It is undoubtedly the case, however, that Kaveny's exemplars of indictment such as Jonah, Lincoln, and King innovated and developed the covenant, even as they invoked it. This complaint aside, Kaveny's book is a major contribution to contemporary conceptualizations of the public square, and stands poised to open new directions for moral analysis of religious actors in pluralistic publics.

This paper studies the influence of agency conflicts on the irreversibility effect. Using a dynamic variant of the static Baron and Myerson :911–930, 1982) adverse selection model, we characterize under which circumstances the irreversibility effect arises in the presence and absence of an agency conflict. In particular, we find that in the presence of an agency conflict the irreversibility effect arises in more circumstances than in the standard first-best analysis that abstracts from agency problems.

This paper examined the integrity, impact and good governance value of election prophecies (EPs) in the last 20 years in selected African countries juxtaposed with President Donald Trump’s EPs in America. As a primary source, empirical research was conducted alongside a historical survey. The data collected from 519 respondents revealed that a majority believe in prophecies, but they queried the integrity, impact and value of EPs due to the inconsistency, inaccuracy, confusion and unhealthy public panics engendered. Despite the adverse effects, (...) many adherents still subscribe to the phenomenon due to the psychological and emotional influence. Subsequently, this article critiqued the research outcome through Biblical Theology. It held that EPs remain vital in the public life of nations, but the current approach in Africa needs some review. These include: (1) the need to revisit the tasks of prophets as Hope givers, Reformers and those who speak truth to power in pre- and post-election seasons; (2) the scrutiny of EPs by the plurality of Prophets, ecumenical leaders and the public, with the four suggested evaluation indices; and (3) the need to curb the negative effect of EPs on healthy electoral processes using enacted public account policies. Contribution: This article contributes to an interdisciplinary religious aspect of research covering Biblical theology, psephology and politics. (shrink)

A self-fulfilling prophecy is, roughly, a prediction that brings about its own truth. Although true predictions are hard to fault, self-fulfilling prophecies are often regarded with suspicion. In this article, we vindicate this suspicion by explaining what self-fulfilling prophecies are and what is problematic about them, paying special attention to how their problems are exacerbated through automated prediction. Our descriptive account of self-fulfilling prophecies articulates the four elements that define them. Based on this account, we begin our critique by showing (...) that typical self-fulfilling prophecies arise due to mistakes about the relationship between a prediction and its object. Such mistakes—along with other mistakes in predicting or in the larger practical endeavor—are easily overlooked when the predictions turn out true. Thus we note that self-fulfilling prophecies prompt no error signals; truth shrouds their mistakes from humans and machines alike. Consequently, self-fulfilling prophecies create several obstacles to accountability for the outcomes they produce. We conclude our critique by showing how failures of accountability, and the associated failures to make corrections, explain the connection between self-fulfilling prophecies and feedback loops. By analyzing the complex relationships between accuracy and other evaluatively significant features of predictions, this article sheds light both on the special case of self-fulfilling prophecies and on the ethics of prediction more generally.

There are currently two legally established criteria for death: the irreversible cessation of circulation and respiration and the irreversible cessation of neurologic function. Recently, there have been technological developments that could undermine the irreversibility requirement. In this paper, I focus both on whether death should be identified as an irreversible state and on the proper scope of irreversibility in the biological definition of death. In this paper, I tackle the distinction between the commonsense definition of death and (...) the biological definition of death to show that even the commonsense concept of death is specified by biological facts. Resting on this argument, I argue that any definition of death is a posteriori. Thus, irreversibility is part of any definition of death because the actual phenomenon of death is irreversible. In addition, I show that the proper domain of irreversibility in a definition of death is circumscribed by physical possibilities and that irreversibility in the definition of death refers to current possibilities for the reversal of relevant biological processes. I conclude that, despite recent technological advancements, death is still irreversible. (shrink)

We discuss Boltzmann’s probabilistic explanation of the second law of thermodynamics providing a comprehensive presentation of what is called today the typicality account. Countering its misconception as an alternative explanation, we examine the relation between Boltzmann’s H-theorem and the general typicality argument demonstrating the conceptual continuity between the two. We then discuss the philosophical dimensions of the concept of typicality and its relevance for scientific reasoning in general, in particular for understanding the reduction of macroscopic laws to microscopic laws. Finally, (...) we reply to various common criticisms of the typicality account. (shrink)

This paper explores a distinction among causal relationships that has yet to receive attention in the philosophical literature, namely, whether causal relationships are reversible or irreversible. We provide an analysis of this distinction and show how it has important implications for causal inference and modeling. This work also clarifies how various familiar puzzles involving preemption and over-determination play out differently depending on whether the causation involved is reversible.

A self-fulfilling prophecy in neuroprognostication occurs when a patient in coma is predicted to have a poor outcome, and life-sustaining treatment is withdrawn on the basis of that prediction, thus directly bringing about a poor outcome for that patient. In contrast to the predominant emphasis in the bioethics literature, we look beyond the moral issues raised by the possibility that an erroneous prediction might lead to the death of a patient who otherwise would have lived. Instead, we focus on the (...) problematic epistemic consequences of neuroprognostic SFPs in settings where research and practice intersect. When this sort of SFP occurs, the problem is that physicians and researchers are never in a position to notice whether their original prognosis was correct or incorrect, since the patient dies anyway. Thus, SFPs keep us from discerning false positives from true positives, inhibiting proper assessment of novel prognostic tests. This epistemic problem of SFPs thus impedes learning, but ethical obligations of patient care make it difficult to avoid SFPs. We then show how the impediment to catching false positive indicators of poor outcome distorts research on novel techniques for neuroprognostication, allowing biases to persist in prognostic tests. We finally highlight a particular risk that a precautionary bias towards early withdrawal of life-sustaining treatment may be amplified. We conclude with guidelines about how researchers can mitigate the epistemic problems of SFPs, to achieve more responsible innovation of neuroprognostication for patients in coma. (shrink)

The distinction between the "permanent" (will not reverse) and "irreversible" (cannot reverse) cessation of functions is critical to understand the meaning of a determination of death using circulatory–respiratory tests. Physicians determining death test only for the permanent cessation of circulation and respiration because they know that irreversible cessation follows rapidly and inevitably once circulation no longer will restore itself spontaneously and will not be restored medically. Although most statutes of death stipulate irreversible cessation of circulatory and respiratory (...) functions, the accepted medical standard is their permanent cessation because permanence is a perfect surrogate indicator for irreversibility, and using it permits a more timely declaration. Therefore, patients properly declared dead in donation after circulatory death (DCD) protocols satisfy the requirements of death statutes and do not violate the dead donor rule. The acronym DCD should represent organ "donation after circulatory death" to clarify that the death standard is the permanent cessation of circulation, not heartbeat. Heart donation in DCD does not retroactively negate the donor's death determination because circulation has ceased permanently. (shrink)

_Pragmatism Ascendent_ is the last of four volumes on the contribution of pragmatism to American philosophy and Western philosophy as a whole. It covers the period of American philosophy's greatest influence worldwide, from the second half of the 20th century through the beginning of the 21st. The book provides an account of the way pragmatism reinterprets the revolutionary contributions of Kant and Hegel, the significance of pragmatism's original vision, and the expansion of classic pragmatism to incorporate the strongest themes of (...) Hegelian and Darwinian sources. In the process, it addresses many topics either scanted or not addressed at all in most overviews of the pragmatism's relevance today. Noting the conceptual stalemate, confusion, and inertia of much of current Western philosophy, Margolis advances a new line of inquiry. He considers a fresh conception of the human agent as a hybrid artifact of enlanguaged culture, the decline of all forms of cognitive privilege, the pragmatist sense of the practical adequacy of philosophical solutions, and the possibilities for a recuperative convergence of the best resources of Western philosophy's most viable movements.

When an individual is comatose while parts of her brain remain functional, the question arises as to whether any mental characteristics are still associated with this brain, that is, whether the person still exists. Settling this uncertainty requires that one becomes clear about two issues: the type of functional loss that is associated with the respective profile of brain damage and the persistence conditions of persons. Medical case studies can answer the former question, but they are not concerned with the (...) latter. Conversely, in the philosophical literature, various accounts of personal identity are discussed, but usually detached from any empirical basis. Only uniting the two debates and interpreting the real-life configurations of brain damage through the lens of the philosophical concepts enables one to make an informed judgment regarding the persistence of comatose persons. Especially challenging are cases in which three mental characteristics that normally occur together—wakefulness, awareness and memory storage—come apart. These shall be the focus of this paper.

The aim of this paper is to analyze time-asymmetric quantum mechanics with respect of its validity as a non time-reversal invariant, time-asymmetric theory as well as of its ability to determine an arrow of time.

The aim of this paper is to analyze time-asymmetric quantum mechanics with respect to the problems of irreversibility and of time's arrow. We begin with arguing that both problems are conceptually different. Then, we show that, contrary to a common opinion, the theory's ability to describe irreversible quantum processes is not a consequence of the semigroup evolution laws expressing the non-time-reversal invariance of the theory. Finally, we argue that time-asymmetric quantum mechanics, either in Prigogine's version or in Bohm's version, (...) does not solve the problem of the arrow of time because it does not supply a substantial and theoretically founded criterion for distinguishing between the two directions of time.

There has recently been a good deal of controversy about Landauer's Principle, which is often stated as follows: The erasure of one bit of information in a computational device is necessarily accompanied by a generation of kTln2 heat. This is often generalised to the claim that any logically irreversible operation cannot be implemented in a thermodynamically reversible way. John Norton (2005) and Owen Maroney (2005) both argue that Landauer's Principle has not been shown to hold in general, and Maroney (...) offers a method that he claims instantiates the operation Reset in a thermodynamically reversible way. In this paper we defend the qualitative form of Landauer's Principle, and clarify its quantitative consequences (assuming the second law of thermodynamics). We analyse in detail what it means for a physical system to implement a logical transformation L, and we make this precise by defining the notion of an L-machine. Then we show that logical irreversibility of L implies thermodynamic irreversibility of every corresponding L-machine. We do this in two ways. First, by assuming the phenomenological validity of the Kelvin statement of the second law, and second, by using information-theoretic reasoning. We illustrate our results with the example of the logical transformation 'Reset', and thereby recover the quantitative form of Landauer's Principle. (shrink)

It has been a longstanding problem to show how the irreversible behaviour of macroscopic systems can be reconciled with the time-reversal invariance of these same systems when considered from a microscopic point of view. A result by Lanford shows that, under certain conditions, the famous Boltzmann equation, describing the irreversible behaviour of a dilute gas, can be obtained from the time-reversal invariant Hamiltonian equations of motion for the hard spheres model. Here, we examine how and in what sense (...) Lanford’s theorem succeeds in deriving this remarkable result. Many authors have expressed different views on the question which of the ingredients in Lanford’s theorem is responsible for the emergence of irreversibility. We claim that these interpretations miss the target. In fact, we argue that there is no time-asymmetric ingredient at all. (shrink)

Ocean-based salmon farming, as presently practiced, is thought to pose an existential threat to what we today think of as wild salmon. This raises ethical questions about, first, the value of wild salmon, and, second, the value of wild salmon of the particular type that exists today. This essay uses the debate around ocean-based salmon farming as a case study of ‘irreversible damage’, a concept that figures heavily in environmental laws and regulations, in particular, in the so-called ‘precautionary principle’. (...) It is argued that although ocean-based salmon farming may, on the face of it, seem to be a prime example of a threat of irreversible damage, a wish to avoid irreversible damage does not support banning such farming. In contrast, it is argued that concern for irreplaceable value might support a ban. The findings suggest that it would often be appropriate for environmentalists and conservationists to focus more on irreplaceable value and less on irreversible damage. (shrink)

Predictions of poor prognosis for critically ill patients may become self-fulfilling if life-sustaining treatment or resuscitation is subsequently withheld on the basis of that prediction. This paper outlines the epistemic and normative problems raised by self-fulfilling prophecies (SFPs) in intensive care. Where predictions affect outcome, it can be extremely difficult to ascertain the mortality rate for patients if all treatment were provided. SFPs may lead to an increase in mortality for cohorts of patients predicted to have poor prognosis, they may (...) lead doctors to feel causally responsible for the deaths of their patients, and they may compromise honest communication with patients and families about prognosis. However, I argue that the self-fulfilling prophecy is inevitable when life-sustaining treatment is withheld or withdrawn in the face of uncertainty. SFPs do not necessarily make treatment limitation decisions problematic. To minimize the effects of SFPs, it is essential to carefully collect and appraise evidence about prognosis. Doctors need to be honest with themselves and with patients and their families about uncertainty and the limits of knowledge. (shrink)

Should the process of ecological restoration be considered a type of moral reparation? In a recent issue of this journal, Ben Almassi (2017) has argued that ecological restoration should be understood as a moral repair, i.e., as "a model for rebuilding the moral conditions of relationships" (20). Ideas of restorative justice and moral repair are appropriate to address human injustice and wrongdoing. But these concepts are vacuous and lose their meaning when addressing the ethics of human activities regarding the natural (...) world because of the essential character of the restoration process: the replacement or substitution of new entities for pre-existing entities in an attempt to reverse the irreversible. At best, the idea of moral reparations to nature is a weak metaphor with no practical efficacy; at worst, it totally misconceives the relationship between human activity and the natural environment in the process of ecological restoration and provides yet another dangerous and disingenuous justification of human arrogance and domination of the natural world. In the guise of the act of moral reparations, humans are instead attempting to assume the powers of God, to control the natural and human world. My previous criticisms of the ethics and meaning of ecological restorations—especially regarding the substitution of new individuals and the artifactual nature of restorations—can be used to undermine Almassi's thesis of moral repair as a goal of ecological restoration practice. In addition an analysis of the Book of Job in the Old Testament demonstrates that not even God—much less humans—can restore and replace what has been destroyed. (shrink)
