ABSTRACT Persons injured as a result of exposure to toxic or carcinogenic substances are seldom able to recover damages from those who are responsible for the exposure. Tort law requires proof of causation, and causation is often unprovable because of long latency periods, because of the relative infrequency of the injuries and because many of the injuries among the exposed population are the result of other factors. A number of proposals for modifying the legal causation requirement to allow those who (...) create hazardous risks to be held liable for the injuries that materialise are considered and found inadequate. A proposal to treat risk exposure itself as an injury for which compensation under private law is possible is also considered and ultimately found incoherent. The paper concludes by arguing for a public law solution, modelled on criminal law, but providing compensation for victims. (shrink)

The interdisciplinary relevance of Spinoza today.

In this essay, I trace the motif of abandonment that runs through the ethics of Simone Weil. In doing so, as a conceptual lens, I make use of Giorgio Agamben’s concept of abandonment. Taking my cue from Weil’s hesitations concerning baptism, I examine her stance as a case of either sacrifice or exception, of ambiguity or indifference. Subsequently, I use Weil’s hesitations to examine an interconnected sequence of soteriology and metaphysics, following Church and potentiality, World and actuality, and The Kingdom (...) and contingency. This allows me to explore the themes of writing and life. A crucial role is reserved for the Parable of the Sower, and how it discriminates between the saved and the damned. (shrink)

George Boolos's employment of plurals to give an ontologically innocent interpretation of monadic higher‐order quantification continues and extends a minority tradition in thinking about quantification and ontological commitment. An especially prominent member of that tradition is Stanislaw Leśniewski, and shall first draw attention to this work and its relation to that of Boolos. Secondly I shall stand up briefly for plurals as logically respectable expressions, while noting their limitations in offering ontologically deflationary accounts of higher‐order quantification. Thirdly I shall focus (...) on the key idea of ontological commitment and investigate its connection with the idea of truth‐making. Fourthly I shall consider how different interpretations of quantification may sideline Boolos's work, but finally I shall largely support his analysis of quantification involving nominal expressions, while arguing, in the spirit of Arthur Prior, that non‐nominal quantification is non‐committing.

In 1924, Bohr, Kramers and Slater tried to introduce into microphysics conservation principles that hold only on the average. This attempt was abandoned in the light of the Compton-Simon experiment. Since that time, except for a moment of doubt in 1936, it has been thought that the classical conservation laws hold in quantum theory for each individual interaction, in a way that yields the classical exchange-and-balance of momentum familiar from the laws of elastic collisions. It has been thought, that (...) is, that in each individual “collision” what one part of the total system loses in linear momentum another part gains, so as to maintain the same total amount afterwards as before. To those familiar with discussions of the interpretation of quantum theory, however, it will be apparent that the very concepts needed to express this idea of an elastic collision are generally not admitted in the theory. For one needs the idea that both before and after collision the total system has a well-defined value for the conserved quantity and, moreover, that the various component parts of the system have well-defined values for those quantities out of which the conserved one is composed. But in the case of spin, for example, it is customary to say that although total spin may be conserved in certain interactions one cannot attribute values to the separate components of spin because the associated operators do not commute. Moreover, one does not generally refer to the values of quantities except in eigenstates. Hence, in general, one would not refer to the value of the conserved quantity before and after interaction, except for interactions initiated in eigenstates. (shrink)

Erasmus of Rotterdam was the greatest Christian humanist scholar of the Northern European Renaissance, a correspondent of Sir Thomas More and many other learned men of his time, known to his contemporaries and to posterity for subtlety of his thought and the depth of his learning. He was also, according to some modern writers, an anti-Semite. In this complete analysis of all of Erasmus' writings on Jews and Judaism, Shimon Markish asserts that the accusation cannot be sustained. For Markish, to (...) ask whether Erasmus was a friend or enemy of the Jews is to ask a modern question of a sixteenth-century man, whose attitude can best be called "asemitism." Erasmus' chief preoccupation was with the future of "the true philosophy of Christ"; he had little interest in the Jewish community of his own time. Erasmus and the Jews discusses Erasmus' critique of Mosaic law and his view of the conflict between "Judaism" as legalistic morality and Jesus' teaching; his judgment on the Pharisees of Jesus' time; his emphasis on the importance of the study of Hebrew; and his opinions of sixteenth-century Jews. This meticulous analysis reveals an Erasmus who defended his vision of true piety by rejecting "Judaizing" Christians more than Jews and who saw the Old Testament as integral to the Christian worldview. As a Christian, he regretted nonbelief and pitied unbelievers, without vicious hostility toward any single people. His theological opposition to a form of religious thought which he identified with Judaism was not translated into crude prejudice against actual Jews. In general, his calm consideration of the strange and the foreign and his willingness to restrict his judgments to the philosophical realm were, Markish argues, early and significant steps toward enlightened toleration. Markish's discussion of Erasmus is supplemented with an Afterword by theologian and philosopher Arthur A. Cohen, who offers a variant interpretation of Erasmus' writings and attitudes. The juxtaposed arguments of the two scholars make this an especially illuminating work for any student of Erasmus and his influence. Erasmus and the Jews also gives a necessary clarity to our understanding of the meaning of anti-Semitism and the history of religious toleration. Markish's profound knowledge of Erasmus allows him to demonstrate the fundamental importance of putting arguments and terminology in the context of a thinker's work and his own time. (shrink)

I consider the idea of a propositional logic of location based on the following semantic framework, derived from ideas of Prior. We have a collection L of locations and a collection S of statements such that a statement may be evaluated for truth at each location. Typically one and the same statement may be true at one location and false at another. Given this semantic framework we may proceed in two ways: introducing names for locations, predicates for the relations among (...) them and an “at” preposition to express the value of statements at locations; or introduce statement operators which do not name locations but whose truth-conditional effect depends on the truth or falsity of embedded statements at various locations. The latter is akin to Prior’s approach to tense logic. In any logic of location there will be some basic operators which we can define. By ringing the changes on the topology of locations, different logical systems may be generated, and the challenge for the logician is then in each case to find operators, axioms and rules yielding a proof theory adequate to the semantics. The generality of the approach is illustrated with familiar and not so familiar examples from modal, tense and place logic, mathematics, and even the logic of games. To the memory of Ted Dawson, who introduced me to philosophy and the writings of Arthur Prior. (shrink)

Herbert Simon once observed that watching an ant make its way across the uneven surface of a beach, one can easily be impressed—too impressed—with the foresight and complexity of the ant's internal map of the beach. Simon went on to point out that such an attribution of complexity to the ant makes a serious mistake. Most of the complexity is not in the ant but in the beach. The ant is just complex enough to use the features of (...) the beach to find its way. (shrink)

Art, as discussed in the third book of Arthur Schopenhauer’s The World as Will and Representation, plays a double role in his philosophical system. On one hand, beholding an object of aesthetic worth provides the spectator with a temporary cessation of the otherwise incessant suffering that Schopenhauer takes life to be; on the other, art creates an epistemological bridge between ourselves and the world as it really is: unlike science which only studies relations between things, contemplation of art leads (...) to knowledge of that which is “alone really essential to the world, the true content of its phenomena.” (WWR1: 184) It is this second aspect of Schopenhauer's aesthetics that is both appealing and curious: while Schopenhauer's aesthetics and epistemology are both rooted in his picture of the world as Will, which is (taken at face value) deeply counter-intuitive, it yet seems to me that by assigning epistemic value to art, he manages to capture the quality of profundity with which certain works of art strike us – a profundity that is accounted for neither by reference to mere enjoyment nor by reference to paraphrasable, propositional knowledge.

No other book in the entire history of the world has exerted a greater influence on a larger number of people over a longer period of time than this slim volume. The spiritual cornerstone of the most populous and oldest living civilization on Earth, the Analects has inspired the Chinese and all the peoples of East Asia with its affirmation of a humanist ethics. As the Gospels are to Jesus, the Analects is the only place where we can encounter the (...) real, living Confucius. In this gem-like translation by Simon Leys, Confucius speaks with clarity and brilliance. He emerges as a man of great passion and many enthusiasms, a man of bold action whose true vocation is politics. Confucius (551-479 B.C.) lived in an age of acute cultural and political crisis. Many of his observations mark a world sinking into violence and barbarity. Unable to obtain the leading political role he sought, he endeavored to reform society and salvage civilization through ethical debate, defining for ages to come the public mission of the intellectual.

Suppose you hold the following opinions in the philosophy of logic. First-order predicate logic is expressively inadequate to regiment concepts of mathematic and natural language; logicism is plausible and attractive; set theory as an adjunct to logic is unnatural and ontologically extravagant; humanly usable languages are finite in lexicon and syntax; it is worth striving for a Tarskian semantics for mathematics; there are no Platonic abstract objects. Then you are probably already in cognitive distress. One way to decease your unhappiness, (...) short for embracing Platonism, is to accept higher-order logic and look, as did Arthur Prior, for a plausible way to neutralize the ontological commitment to abstract entities that this acceptance appears to entail.

In Simone de Beauvoir's Philosophy of Lived Experience, Eleanore Holveck presents Simone de Beauvoir's theory of literature and metaphysics, including its relationship to the philosophers Edmund Husserl, Martin Heidegger, Immanuel Kant, Maurice Merleau-Ponty, and Jean-Paul Sartre, with references to the literary tradition of Goethe, Maurice Barr_s, Arthur Rimbaud, AndrZ Breton, and Paul Nizan. The book provides a detailed philosophical analysis of Beauvoir's early short stories and several major novels, including The Mandarins and L'invitZe.

This is a transcript of Milne's manuscript notes for a talk which he gave to fellow members of the Cambridge University Natural Science Club in his rooms at Trinity College, Cambridge, on February 6, 1922. The notes are deposited in the Bodleian Library, University of Oxford, Special Collections and Western Manuscripts. The background and essential points of Milne's talk are analysed in the article preceding this one. As far as is known, the text has not hitherto been published. Milne's handwriting (...) is difficult to read, and square brackets [...] denote the addition of a word for clarity of meaning. Meg Weston Smith and Simon Rebsdorf have ventured to fill in some chapter titles just in order to help with the separation of the varying content, hence we have made up all the headlines. All italics correspond to underlined words in the original. The Bergson citations and the Eddington passage at the end of the original text have not been transcribed. (shrink)

Simon Kochen and Ernst Specker's well-known argument against hidden variable theories for quantum mechanics is also an argument against the possibility of quantum systems having, simultaneously, precise values for all of the dynamical quantities associated with such systems. Devices for defeating the argument were in the literature even before its publication, but recently Arthur Fine has raised a new difficulty. Fine points out that Kochen and Specker's argument requires the following principles:Sum Rule: At all times, in all states, (...) the value of the quantity with operator A + B is the sum of the values of the quantity with operator A and the quantity with operator B, provided A, B commute.Product Rule: At all times, in all states, the value of the quantity with operator AB is the product of the values of the quantities with operators A and B, provided A, B commute.

Stanisław Leśniewski developed a system of logic and foundations of mathematics that considerably differs from Russell and Whitehead’s system. The difference between these two approaches to logic is significant primarily in the case of Leśniewski’s calculus of names, Ontology, and the concept of names that it contains. Russell’s theory of descriptions played a much more important role than Leśniewski’s concept of names in the history of philosophy. In response to that, several researchers aimed to approximate Leśniewski’s concept of names to (...) Russell’s theory. There are several such attempts. This paper presents an interpretation that was suggested by Arthur Prior. Prior interpreted Leśniewskian names as class names. This interpretation was rejected by such prominent Leśniewskian scholars as Peter Simons or Rafal Urbaniak. According to Simons, class names oppose Leśniewski’s ontological views. Urbaniak claimed that Prior’s interpretation of Leśniewskian names as class names is unclear. The aim of this paper is to demonstrate that from the formal point of view, Prior’s interpretation could be justified. (shrink)

Now in its third edition, _Narration and Knowledge_ is a classic work exploring the nature of historical knowledge and its reliance on narrative. Analytical philosopher Arthur C. Danto introduces the concept of "narrative sentences," in which an event is described with reference to later events and discusses why such sentences cannot be understood until the later event happens. Danto compares narrative and scientific explanation and explores the legitimacy of historical laws. He also argues that history is an autonomous and (...) humanist discipline incapable of being reduced to scientific descriptions. Lydia Goehr's new introduction illustrates Danto's main arguments by questioning her very role, first, as an introducer of a book that has not yet been read by readers and, second, as an interpreter of a book written forty years ago. Frank Ankersmit's conclusion revisits the initial impact of the publication of _Narration and Knowledge_ and considers its enduring legacy. (shrink)

A recent study by Olivieri et al, published in PLOS ONE, reports that between 2009 and 2015 a third of patients with thalassaemia in Canada’s largest hospital were switched from first-line licensed drugs to regimens of deferiprone, an unlicensed drug of unproven safety and efficacy. Based on retrospective data from patient records, the PLOS Study reports that patients treated with deferiprone, either as monotherapy or in combination with first-line drugs, suffered serious adverse effects. The data reported by Olivieri et al (...) give rise to a number of ethical issues. These ethical issues are identified, placed in historical context and analysed. For purposes of this analysis, reliance is placed on two core principles of research ethics, harm minimisation and informed consent, and also on the hospital’s mission statement. Then a mystery is explored: How and why did it happen that Toronto’s University Health Network treated large numbers of patients with an unlicensed drug over a period of many years? ‘Institutional conflict of interest’ is considered as a possible explanatory hypothesis.

This is a very short introduction to ethics. It divides into three parts: first, introducing and discussing reasons for skepticism about ethics; second introducing themes of birth, death, happiness, desire and freedom to show how deeply our lives are interwoven with ethics; third, introducing attempts to found ethics, due to Aristotle, Kant, and the contractarian tradition.

Cannabis use in some individuals can meaningfully introduce de novo risk for the initiation of opioid use and development of opioid use disorder. These risks may be particularly high during adolescence when cannabis use may disrupt critical periods of neurodevelopment. Current research studying the combination of genetic and environmental factors involved in substance use disorders is poorly understood. More research is needed, particularly to identify which adolescents are most at risk and to develop effective interventions addressing contributing factors such as (...) trauma and psychiatric comorbidity.

Many animals will invent new behaviour patterns, adjust established behaviours to a novel context, or respond to stresses in an appropriate and novel manner. This is the first ever book on the topic of 'animal innovation'. Bringing together leading scientific authorities on animal and human innovation, this book will put the topic of animal innovation on the map, and heighten awareness of this developing field.

Graham Harman describes the allure of art as the tension and fusion of a real object to sensual qualities so that it makes it seem that the inwardness of reality is opened to us. Yet real objects are withdrawn; how are we aware of their fusion? Since Harman’s ontology mandates that contact between real objects occurs only through sensual objects, this essay explores the idea that art’s allure must be a tension between sensual objects that draw the experiencer to believe, (...) or alieve, they are in contact with the withdrawn real. By looking at the examples in representational painting and sleight of hand magic, we see that ontographic art objects use at least four, carefully separated sensual objects to produce their aesthetic effect. The conclusion summarises allure as a sensual object process, speculates on art’s dialetheic confusion of sensual and real objects giving an enduring allure to idealism, and notes potential motifs of an infra-realist resistance.

We study the handicap principle in terms of the Sir Philip Sidney game. The handicap principle asserts that cost is required to allow for honest signalling in the face of conflicts of interest. We show that the significance of the handicap principle can be challenged from two new directions. Firstly, both the costly signalling equilibrium and certain states of no communication are stable under the replicator dynamics ; however, the latter states are more likely in cases where honest signalling should (...) apply. Secondly, we prove the existence and stability of polymorphisms where players mix between being honest and being deceptive and where signalling costs can be very low. Neither the polymorphisms nor the states of no communication are evolutionarily stable, but they turn out to be more important for standard evolutionary dynamics than the costly signalling equilibrium.

In this paper we argue that the consensus around normative standards for the ethics of research in clinical trials, strongly influenced by the Declaration of Helsinki, is perceived from various quarters as too conservative and potentially restrictive of research that is seen as urgent and necessary. We examine this problem from the perspective of various challengers who argue for alternative approaches to what ought or ought not to be permitted. Key themes within this analysis will examine these claims and argue (...) they have implications for the interests of the research subject, research governance and regulation. Using our work with TREAT-NMD, the neuromuscular clinical trials network, we posit that there is a place for advancing the discourse of moral rights and moral duties in the context of research, especially from the perspective of patients and their families, and for including the politics of patient activism and empowerment. At the same time we remain vigilant to the danger that the therapeutic misconception and other serious vulnerabilities for the patient population in clinical trials, are at risk of being overlooked.

Online exam supervision technologies have recently generated significant controversy and concern. Their use is now booming due to growing demand for online courses and for off-campus assessment options amid COVID-19 lockdowns. Online proctoring technologies purport to effectively oversee students sitting online exams by using artificial intelligence systems supplemented by human invigilators. Such technologies have alarmed some students who see them as a “Big Brother-like” threat to liberty and privacy, and as potentially unfair and discriminatory. However, some universities and educators defend (...) their judicious use. Critical ethical appraisal of online proctoring technologies is overdue. This essay provides one of the first sustained moral philosophical analyses of these technologies, focusing on ethical notions of academic integrity, fairness, non-maleficence, transparency, privacy, autonomy, liberty, and trust. Most of these concepts are prominent in the new field of AI ethics, and all are relevant to education. The essay discusses these ethical issues. It also offers suggestions for educational institutions and educators interested in the technologies about the kinds of inquiries they need to make and the governance and review processes they might need to adopt to justify and remain accountable for using online proctoring technologies. The rapid and contentious rise of proctoring software provides a fruitful ethical case study of how AI is infiltrating all areas of life. The social impacts and moral consequences of this digital technology warrant ongoing scrutiny and study. (shrink)
