We summarize a new realist, unextravagant interpretation of quantum theory that builds on the existing physical structure of the theory and allows experiments to have definite outcomes but leaves the theory's basic dynamical content essentially intact. Much as classical systems have specific states that evolve along definite trajectories through configuration spaces, the traditional formulation of quantum theory permits assuming that closed quantum systems have specific states that evolve unitarily along definite trajectories through Hilbert spaces, and our interpretation extends this intuitive (...) picture of states and Hilbert-space trajectories to the more realistic case of open quantum systems despite the generic development of entanglement. Our interpretation—which we claim is ultimately compatible with Lorentz invariance—reformulates wave-function collapse in terms of an underlying interpolating dynamics, makes it possible to derive the Born rule from deeper principles, and resolves several open questions regarding ontological stability and dynamics.

Any realist interpretation of quantum theory must grapple with the measurement problem and the status of state-vector collapse. In a no-collapse approach, measurement is typically modeled as a dynamical process involving decoherence. We describe how the minimal modal interpretation closes a gap in this dynamical description, leading to a complete and consistent resolution to the measurement problem and an effective form of state collapse. Our interpretation also provides insight into the indivisible nature of measurement—the fact that you can't stop a (...) measurement part-way through and uncover the underlying 'ontic' dynamics of the system in question. Having discussed the hidden dynamics of a system's ontic state during measurement, we turn to more general forms of open-system dynamics and explore the extent to which the details of the underlying ontic behavior of a system can be described. We construct a space of ontic trajectories and describe obstructions to defining a probability measure on this space. (shrink)

We introduce a realist, unextravagant interpretation of quantum theory that builds on the existing physical structure of the theory and allows experiments to have definite outcomes but leaves the theory’s basic dynamical content essentially intact. Much as classical systems have specific states that evolve along definite trajectories through configuration spaces, the traditional formulation of quantum theory permits assuming that closed quantum systems have specific states that evolve unitarily along definite trajectories through Hilbert spaces, and our interpretation extends this intuitive picture (...) of states and Hilbert-space trajectories to the more realistic case of open quantum systems despite the generic development of entanglement. We provide independent justification for the partial-trace operation for density matrices, reformulate wave-function collapse in terms of an underlying interpolating dynamics, derive the Born rule from deeper principles, resolve several open questions regarding ontological stability and dynamics, address a number of familiar no-go theorems, and argue that our interpretation is ultimately compatible with Lorentz invariance. Along the way, we also investigate a number of unexplored features of quantum theory, including an interesting geometrical structure—which we call subsystem space—that we believe merits further study. We conclude with a summary, a list of criteria for future work on quantum foundations, and further research directions. We include an appendix that briefly reviews the traditional Copenhagen interpretation and the measurement problem of quantum theory, as well as the instrumentalist approach and a collection of foundational theorems not otherwise discussed in the main text.

What determines whether an action is right or wrong? Morality, Rules, and Consequences: A Critical Reader explores for students and researchers the relationship between consequentialist theory and moral rules. Most of the chapters focus on rule consequentialism or on the distinction between act and rule versions of consequentialism. Contributors, among them the leading philosophers in the discipline, suggest ways of assessing whether rule consequentialism could be a satisfactory moral theory. These essays, all of which are previously unpublished, provide students in (...) moral philosophy with essential material and ask key questions on just what the criteria for an adequate moral theory might be.

Recovering Reason: Essays in Honor of Thomas L. Pangle is a collection of essays composed by students and friends of Thomas L. Pangle to honor his seminal work and outstanding guidance in the study of political philosophy. These essays examine both Socrates' and modern political philosophers' attempts to answer the question of the right life for human beings, as those attempts are introduced and elaborated in the work of thinkers from Homer and Thucydides to Nietzsche and Charles Taylor.

Kagan argues that human beings who are neither persons nor even potential persons — if their impairment is independent of genetic constitution — are modal persons: individuals who might have been persons. Moreover, he proposes a view according to which both personhood and modal personhood are sufficient for counting more, morally, than nonhuman animals. In response to this proposal, I raise one relatively minor concern about Kagan's reasoning — that he judges too quickly that insentient beings can have (...) interests — before engaging the appeal to modal personhood. I challenge the thesis that modal personhood is relevant to one's moral status, first, by way of analogy to a kicker who misses a field goal though he might have made it; second, by casting doubt on implications for two impaired infants ; and, finally, by examining implications for dogs who would count as modal persons when genetic enhancements are capable of transforming them into persons.

Shelly Kagan and Leonard Katz have offered versions of hedonism that aspire to occupy a middle position between the view that pleasure is a unitary sensation and the view that pleasure is, as Sidgwick put it, desirable consciousness. Thus they hope to offer a hedonistic account of well-being that does not mistakenly suppose that pleasure is a special kind of tingle, yet to offer a sharp alternative to desire-based accounts. I argue that they have not identified a coherent middle (...) position. (shrink)

An alternative approach to emotion is presented here, which differs from that of Kagan and others. It orders emotion along a continuum of the embodiment of emotion, starting with a clear but rare case of pure emotion and at the other extreme discusses Damasio’s intelligent prefrontal patients who could not feel emotions critical to social life.

Few philosophers today embrace quantitative hedonism, which states that a person’s well-being depends only on the amount of her experienced happiness and suffering. Despite recent attempts to rehabilitate it, most philosophers still consider it untenable. The most influential arguments levelled against it by Mill, Moore, Nozick and Kagan purport to demonstrate that well-being must depend on more than only the amount of experienced happiness and suffering. I argue in this paper that quantitative hedonism can rebut these arguments by pointing (...) out a shared systematic flaw in their argumentative structure. In particular, I argue that they are based on thought experiments that invoke either structurally unreliable intuitions or intuitions that are not in tension to the tenets of quantitative hedonism. While this does not rehabilitate the theory by itself, it shows that the classical arguments against quantitative hedonism provide far less evidence against it than commonly thought. (shrink)

The convergence of human and artificial intelligence is currently receiving considerable scholarly attention. Much debate about the resulting _Hybrid Minds_ focuses on the integration of artificial intelligence into the human brain through intelligent brain-computer interfaces as they enter clinical use. In this contribution we discuss a complementary development: the integration of a functional in vitro network of human neurons into an _in silico_ computing environment. To do so, we draw on a recent experiment reporting the creation of silico-biological intelligence as (...) a case study (Kagan et al., 2022b ). In this experiment, multielectrode arrays were plated with stem cell-derived human neurons, creating a system which the authors call _DishBrain_. By embedding the system into a virtual game-world, neural clusters were able to receive electrical input signals from the game-world and to respond appropriately with output signals from pre-assigned motor regions. Using this design, the authors demonstrate how the _DishBrain_ self-organises and successfully learns to play the computer game ‘Pong’, exhibiting ‘sentient’ and intelligent behaviour in its virtual environment. The creation of such hybrid, silico-biological intelligence raises numerous ethical challenges. Following the neuroscientific framework embraced by the authors themselves, we discuss the arising ethical challenges in the context of Karl Friston’s Free Energy Principle, focusing on the risk of creating synthetic phenomenology. Following the _DishBrain’s_ creator’s neuroscientific assumptions, we highlight how DishBrain’s design may risk bringing about artificial suffering and argue for a congruently cautious approach to such synthetic biological intelligence.

Act-utilitarianism claims that one is required to do nothing less than what makes the largest contribution to overall utility. Critics of this moral theory commonly charge that it is unreasonably demanding. Shelly Kagan and David Brink, however, have recently defended act-utilitarianism against this charge. Kagan argues that act-utilitarianism is right, and its critics wrong, about how demanding morality is. In contrast, Brink argues that, once we have the correct objective account of welfare and once we accept that (...) act-utilitarianism is a criterion of moral rightness, not necessarily a good method for everyday moral thought, act-utilitarianism is not as demanding as its critics claim. I shall argue that Brink's arguments for thinking act-utilitarianism is not so demanding fail. I shall then argue against Kagan that, in comparison with act-utilitarianism, rule-utilitarianism is considerably less demanding and more plausible. (shrink)

The nomadic Kazaks inhabiting Xinjiang Province, China, retain many aspects of their pre‐Islamic way of life, including the use of methods of traditional healing usually classified under the rubric of "shamanism." These practices are closely related to those in Kazakstan, Mongolia, and other parts of the former Soviet Union.The present study addresses aspects of traditional healing in use among the Xinjiang Kazaks in recent times, and presents a native taxonomy of these practices obtained during recent fieldwork in Xingjiang. Special attention (...) is paid to the use of words, sound, and movement in healing contexts by elders and specialized individuals. (shrink)

Part of the appeal of the biological approach to personal identity is that it does not have to countenance spatially coincident entities. But if the termination thesis is correct and the organism ceases to exist at death, then it appears that the corpse is a dead body that earlier was a living body and distinct from but spatially coincident with the organism. If the organism is identified with the body, then the unwelcome spatial coincidence could perhaps be avoided. It is (...) argued that such an identification would be a mistake. A living organism has a different part/whole relationship and persistence conditions than the alleged body. A case will be made that the concept ‘human body’ is a conceptual mess, vague in an unprincipled manner, and that an eliminativist stance towards dead bodies is the appropriate response.

As a continuation of the work of the third author in [5], we make further observations on the features of Galois cohomology in the general model theoretic context. We make explicit the connection between forms of definable groups and first cohomology sets with coefficients in a suitable automorphism group. We then use a method of twisting cohomology (inspired by Serre’s algebraic twisting) to describe arbitrary fibres in cohomology sequences—yielding a useful “finiteness” result on cohomology sets. Applied to the special case (...) of differential fields and Kolchin’s constrained cohomology, we complete results from [3] by proving that the first constrained cohomology set of a differential algebraic group over a bounded, differentially large, field is countable.

Most people believe that there are limits to the sacrifices that morality can demand. Although it would often be meritorious, we are not, in fact, morally required to do all that we can to promote overall good. What's more, most people also believe that certain types of acts are simply forbidden, morally off limits, even when necessary for promoting the overall good. In this provocative analysis Kagan maintains that despite the intuitive appeal of these views, they cannot be adequately (...) defended. In criticizing arguments for limited moral requirements as well as those for unconditionally prohibited acts, Kagan offers a sustained attack on two of the most basic features of ordinary common sense morality.

The moral distress of psychologists working in psychiatric and mental health care settings was explored in an interdisciplinary, hermeneutic phenomenological study situated at the University of Alberta, Canada. Moral distress is the state experienced when moral choices and actions are thwarted by constraints. Psychologists described specific incidents in which they felt their integrity had been compromised by such factors as institutional and interinstitutional demands, team conflicts, and interdisciplinary disputes. They described dealing with the resulting moral distress by such means as (...) silence, taking a stance, acting secretively, sustaining themselves through work with clients, seeking support from colleagues, and exiting. Recognizing moral distress can lead to a significant shift in the way we perceive moral choices and understand the moral context of practice. (shrink)

000000001. Introduction Call a theory of the good—be it moral or prudential—aggregative just in case (1) it recognizes local (or location-relative) goodness, and (2) the goodness of states of affairs is based on some aggregation of local goodness. The locations for local goodness might be points or regions in time, space, or space-time; or they might be people, or states of nature.1 Any method of aggregation is allowed: totaling, averaging, measuring the equality of the distribution, measuring the minimum, etc.. Call (...) a theory of the good finitely additive just in case it is aggregative, and for any finite set of locations it aggregates by adding together the goodness at those locations. Standard versions of total utilitarianism typically invoke finitely additive value theories (with people as locations). A puzzle can arise when finitely additive value theories are applied to cases involving an infinite number of locations (people, times, etc.). Suppose, for example, that temporal locations are the locus of value, and that time is discrete, and has no beginning or end.2 How would a finitely additive theory (e.g., a temporal version of total utilitarianism) judge the following two worlds? Goodness at Locations (e.g. times) w1:..., 2, 2, 2, 2, 2, 2, 2, 2, 2, ..... w2:..., 1, 1, 1, 1, 1, 1, 1, 1, 1, ..... Example 1 At each time w1 contains 2 units of goodness and w2 contains only 1. Intuitively, we claim, if the locations are the same in each world, finitely additive theorists will want to claim that w1 is better than w2. But it's not clear how they could coherently hold this view. For using standard mathematics the sum of each is the same infinity, and so there seems to be no basis for claiming that one is better than the other.3 (Appealing to Cantorian infinities is of no help here, since for any Cantorian infinite N, 2xN=1xN.).

Shelly Kagan argues for a hierarchical position in animal ethics where people count more than animals do, and some animals count more than others. In arguing for his account of morality, Kagan sets out what needs to be done to establish our obligations toward animals and to fulfil our duties to them.

According to the dominant philosophical tradition, intrinsic value must depend solely upon intrinsic properties. By appealing to various examples, however, I argue that we should at least leave open the possibility that in some cases intrinsic value may be based in part on relational properties.

If this is right, of course, then the traditional contrast (...) between intrinsic value and instrumental value is mistaken. (shrink)

There is one thing we can be sure of: we are all going to die. But once we accept that fact, the questions begin. In this thought-provoking book, philosophy professor Shelly Kagan examines the myriad questions that arise when we confront the meaning of mortality. Do we have reason to believe in the existence of immortal souls? Or should we accept an account according to which people are just material objects, nothing more? Can we make sense of the idea (...) of surviving the death of one’s body? If I won’t exist after I die, can death truly be _bad_ for me? Would immortality be desirable? Is fear of death appropriate? Is suicide ever justified? How should I _live_ in the face of death? Written in an informal and conversational style, this stimulating and provocative book challenges many widely held views about death, as it invites the reader to take a fresh look at one of the central features of the human condition—the fact that we will die.

In this innovative study, Lea David critically investigates the relationship between human rights and memory, suggesting that, instead of understanding human rights in a normative fashion, human rights should be treated as an ideology. Conceptualizing human rights as an ideology gives us useful theoretical and methodological tools to recognize the real impact human rights has on the ground. David traces the rise of the global phenomenon that is the human rights memorialization agenda, termed 'Moral Remembrance', and explores what (...) happens once this agenda becomes implemented. Based on evidence from the Western Balkans and Israel/Palestine, she argues that the human rights memorialization agenda does not lead to a better appreciation of human rights but, contrary to what would be expected, it merely serves to strengthen national sentiments, divisions and animosities along ethnic lines, and leads to the new forms of societal inequalities that are closely connected to different forms of corruptions.

Liberal thinkers of the eighteenth and nineteenth centuries were alert to the political costs and human cruelties involved in European colonialism, but they also thought that European expansion held out progressive possibilities. In Progress, Pluralism, and Politics David Williams examines the colonial and anti-colonial arguments of Adam Smith, Immanuel Kant, Jeremy Bentham, and L.T. Hobhouse. Williams locates their ambivalent attitude towards European conquest and colonial rule in a set of tensions between the impact of colonialism on European states, the (...) possibilities of progress in distant and diverse places, and the relationship between universalism and cultural pluralism. In so doing he reveals some of the central ambiguities that characterize the ways that liberal thought has dealt with the reality of an illiberal world. Of particular importance are appeals to various forms of universal history, attempts to mediate between the claims of identity and the reality of difference, and the different ways of thinking about the achievement of liberal goods in other places. Pointing to key elements in still ongoing debates within liberal states about how they should relate to illiberal places, Progress, Pluralism, and Politics enriches the discussion on political thought and the relationship between liberalism and colonialism.

Peter Singer famously argued in Animal Liberation that almost all of us are speciesists, unjustifiably favoring the interests of humans over the similar interests of other animals. Although I long found that charge compelling, I now find myself having doubts. This article starts by trying to get clear about the nature of speciesism, and then argues that Singer's attempt to show that speciesism is a mere prejudice is unsuccessful. I also argue that most of us are not actually speciesists at (...) all, but rather accept a view I call modal personism. Although I am not confident that modal personism can be adequately defended, it is, at the very least, a philosophical view worthy of further consideration. (shrink)

What are the limits of well-being? This question nicely captures one of the central debates concerning the nature of the individual human good. For rival theories differ as to what sort of facts directly constitute a person's being well-off. On some views, well-being is limited to the presence of pleasure and the absence of pain. But other views push the boundaries of well-being beyond this, so that it encompasses a variety of mental states, not merely pleasure alone. Some theories then (...) draw the line here, limiting well-being to the presence of the appropriately broadened set of mental states. But still others extend the limits of well-being even further, so that it is constituted in part by facts that are not themselves mental states at all; on such views, well-being is partly constituted by states of affairs that are “external” to the individual's experiences. In this essay, I want to explore some of this debate by focusing on a particular stretch of the dialectic. That is, I want to think hard about a particular connected series of arguments and counterarguments. These arguments – or, at least, the concerns they seek to express – emerge naturally in the give and take of philosophical discussion. Together they make up a rather simple story, whose plot, in very rough terms, is this: first there is an attempt to push the limits of well-being outward, moving from a narrow to a broader conception; then comes the claim that the resulting notion is too broad, and so we must retreat to a narrower conception after all.

Typically, discussions of well-being focus almost exclusively on the positive aspects of well-being, those elements which directly contribute to a life going well, or better. It is generally assumed, without comment, that there is no need to explicitly discuss ill-being as well—that is, the part of the theory of well-being that specifies the elements which directly contribute to a life going badly, or less well—since (or so it is thought) this raises no special difficulties or problems. But this common assumption (...) is a mistake, since it is far from obvious how to extend even familiar theories of well-being so as to explicitly cover ill-being as well. This paper acts as an introduction to ill-being, noting some of the interesting and overlooked problems ill-being raises for qualitative hedonism, preference theory, and objective list theories. Particular attention is paid, by way of illustration, to the claim that knowledge is an objective good. Assuming this is so, what exactly is the opposite of knowledge, the objective bad which lowers one’s well-being in the same way that knowledge raises it? (shrink)

In this paper I take some initial steps toward exploring and motivating the suggestion that quality of life and level of well-being do not come to the same thing.

David Charles presents a major new study of Aristotle's views on meaning, essence, necessity, and related topics. These interconnected views are central to Aristotle's metaphysics, philosophy of language, and philosophy of science, and are also highly relevant to current philosophical debates. Charles aims to reach a clear understanding of Aristotle's claims and arguments, to assess their truth, and to evaluate their importance to ancient and modern philosophy.
