In this article we introduce and study hyperclass-forcing in the context of an extension of Morse-Kelley class theory, called MK∗∗. We define this forcing by using a symmetry between MK∗∗ models and models of ZFC− plus there exists a strongly inaccessible cardinal. We develop a coding between β-models ℳ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$\mathcal {M}$$ \end{document} of MK∗∗ and transitive models M+ of SetMK∗∗ which will allow us to go from ℳ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} (...) \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$\mathcal {M}$$ \end{document} to M+ and vice versa. So instead of forcing with a hyperclass in MK∗∗ we can force over the corresponding SetMK∗∗ model with a class of conditions. For class-forcing to work in the context of ZFC− we show that the SetMK∗∗ model M+ can be forced to look like Lκ∗[X]\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$L_{\kappa ^*}[X]$$ \end{document}, where κ∗ is the height of M+, κ strongly inaccessible in M+ and X ⊆ κ. Over such a model we can apply definable class forcing and we arrive at an extension of M+ from which we can go back to the corresponding β-model of MK∗∗, which will in turn be an extension of the original ℳ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$\mathcal {M}$$ \end{document}. Our main result combines hyperclass forcing with coding methods of Beller et al. and Friedman to show that every β-model of MK∗∗ can be extended to a minimal such model of MK∗∗ with the same ordinals. A simpler version of the proof also provides a new and analogous minimality result for models of second-order arithmetic. (shrink)

In her recent article, “The One Necessary Condition for a Business Ethics Course: The Teacher Must be a Philosopher,” Ellen Klein argues that philosophers are best qualified to teach business ethics by virtue of their expertise in ethical theory. Klein likens her claim to that of Plato’s “philosopher-king,” who claimed that the philosopher is best suited to be “king,” because he possesses a theoretical understanding of justice. In response to Klein, I point to Aristotle’s objection to Plato, which shows (...) that theoretical knowledge of ethics is not sufficient for making a person ethical, because ethics requires both theoretical and practical knowledge. Ultimately, I argue that in order to have a successful business ethics class, one must address both the issues unique to ethical theory, and the particularstructures and contexts that are unique to making an ethical decision within the business environment.

In this article we show that Morse-Kelley class theory provides us with an adequate framework for class forcing. We give a rigorous definition of class forcing in a model \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$$$ \end{document} of MK, the main result being that the Definability Lemma can be proven without restricting the notion of forcing. Furthermore we show under which conditions the axioms are preserved. We conclude by proving that Laver’s Theorem (...) does not hold for class forcings. (shrink)

In positive theories, we have an axiom scheme of comprehension for positive formulas. We study here the “generalized positive” theory GPK∞+. Natural models of this theory are hyperuniverses. The author has shown in [2] that GPK∞+ interprets the Kelley Morse class theory. Here we prove that GPK∞+ + ACWF and the Kelley-Morse class theory with the axiom of global choice and the axiom “On is ramifiable” are mutually interpretable. This shows that GPK∞+ + ACWF (...) is a “strong” theory since “On is ramifiable” implies the existence of a proper class of inaccessible cardinals. (shrink)

An interesting positive theory is the GPK theory. The models of this theory include all hyperuniverses (see [5] for a definition of these ones). Here we add a form of the axiom of infinity and a new scheme to obtain GPK∞+. We show that in these conditions, we can interprete the Kelley‐Morse theory (KM) in GPK∞+ (Theorem 3.7). This needs a preliminary property which give an interpretation of the Zermelo‐Fraenkel set theory (ZF) in GPK∞+. (...) We also see what happens in the original GPK theory. Before doing this, we first need to study the basic properties of the theory. This is done in the first two sections. (shrink)

This article studies three most basic systems of truth as well as their subsystems over set theory ZF possibly with AC or the axiom of global choice GC, and then correlates them with subsystems of Morse–Kelley class theory MK. The article aims at making an initial step towards the axiomatic study of truth in set theory in connection with class theory. Some new results on the side of class theory, such as conservativity, (...) forcing and some forms of the reflection principle, are also presented. The equivalence results among systems of truth and classes obtained in this article are summarized in Theorem 104 , Theorem 107 and Theorem 108. (shrink)

Assuming the consistency ofZF + “There is an inaccessible number of inaccessibles”, we prove that Kelley Morse theory plus types is not a conservative extension of Kelley-Morse theory.

In this paper I prove the following theorems which are the converses of some results of Judah and Laver (1983) and of Judah and Marshall (1993).-IfKM+ATW is not an extension by definition ofKM (and the model involved is well founded), then the existence of two inaccessible cardinals is consistent with ZF.-IfKM+ATW is not a conservative extension ofKM (and the model involved is well founded), then the existence of an inaccessible number of inaccessible cardinals is consistent with ZF.whereKM is Kelley Morse (...) theory andKM+ATW isKM with types of well-orders.

The class forcing theorem, which asserts that every class forcing notion ${\mathbb {P}}$ admits a forcing relation $\Vdash _{\mathbb {P}}$, that is, a relation satisfying the forcing relation recursion—it follows that statements true in the corresponding forcing extensions are forced and forced statements are true—is equivalent over Gödel–Bernays set theory $\text {GBC}$ to the principle of elementary transfinite recursion $\text {ETR}_{\text {Ord}}$ for class recursions of length $\text {Ord}$. It is also equivalent to the existence of (...) truth predicates for the infinitary languages $\mathcal {L}_{\text {Ord},\omega }$, allowing any class parameter A; to the existence of truth predicates for the language $\mathcal {L}_{\text {Ord},\text {Ord}}$ ; to the existence of $\text {Ord}$ -iterated truth predicates for first-order set theory $\mathcal {L}_{\omega,\omega }$ ; to the assertion that every separative class partial order ${\mathbb {P}}$ has a set-complete class Boolean completion; to a class-join separation principle; and to the principle of determinacy for clopen class games of rank at most $\text {Ord}+1$. Unlike set forcing, if every class forcing notion ${\mathbb {P}}$ has a forcing relation merely for atomic formulas, then every such ${\mathbb {P}}$ has a uniform forcing relation applicable simultaneously to all formulas. Our results situate the class forcing theorem in the rich hierarchy of theories between $\text {GBC}$ and Kelley–Morse set theory $\text {KM}$. (shrink)

A structural (as opposed to Zadeh's quantitative) approach to fuzziness is given, based on the operator "very", which is added to the language of set theory together with some elementary axioms about it. Due to the axiom of foundation and to a lifting axiom, the operator is proved trivial on the cumulative hierarchy of ZF. So we have to drop either foundation or lifting. Since fuzziness concerns complemented predicates rather than sets, a class theory is needed for (...) the very operator. And of them the Kelley-Morse (KM) theory is more appropriate for reasons of class existence. Several definable realizations of the very-operator are presented in KM⁻. In the last section we consider the operator "very" without the lifting axiom on classes of urelements. To each structurally fuzzy set X a traditional quantitative fuzzy set X̄ is assigned -- its quantitative representation. This way we are able partly to recover ordinary fuzzy sets from the structurally fuzzy ones. (shrink)

In this paper, we study when a set-continuous operator has a fixed-point that is the intersection of a directed family. The framework of our study is the Kelley-Morse theory KMC– and the Gödel-Bernays theory GBC–, both theories including an Axiom of Choice and excluding the Axiom of Foundation. On the one hand, we prove a result concerning monotone operators in KMC– that cannot be proved in GBC–. On the other hand, we study conditions on directed superclasses in GBC– (...) in order that their intersection is a fixed-point of a set-continuous operator. Finally, we illustrate our results with a solution to the liar paradox and a construction of maximal bisimulations. (shrink)

By closely examining the sources, movements, and persons of the Renaissance and the Reformation, Voegelin reveals the roots of today's political ideologies in this fourth volume of his _History of Political Ideas._ This insightful study lays the groundwork for Voegelin's critique of the modern period and is essential to an understanding of his later analysis. Voegelin identifies not one but two distinct beginnings of the movement toward modern political consciousness: the Renaissance and the Reformation. Historically, however, the powerful effects of (...) the second have overshadowed the first. In this book, Voegelin carefully examines both periods and their presence in modern thought. The Renaissance, represented by the works of Niccolò Machiavelli, Desiderius Erasmus, and Thomas More, is characterized by a struggle for balance. Machiavelli and Erasmus both looked to a virtuous prince to achieve order, one calling for brute force and the other for Christian spirituality to reach their goal. Also a participant in the first beginning of modernity, More was a complex thinker identified as a saint both of the church and of the communist movement. The issues he explored in _Utopia,_ as Voegelin demonstrates, indirectly gave rise to concepts that have profoundly affected Western history: colonization, imperialism, national socialism, and communism. Exploring the transition from the Renaissance to the Reformation is a brilliant chapter, "The People of God," which examines the sectarian movement. These pages contain the rich historical background that led to Voegelin's later conclusions about Gnosticism and its modern influences. Voegelin offers a controversial view of the Reformation as well as the political and religious situation directly preceding it. Yet he sheds light on the strengths and inadequacies of its key figures, Martin Luther and John Calvin. The driving force behind the Reformation stemmed solely from the powerful personality of Luther. What began as an abstract, purely technical discussion developed into a full-blown revolt. Later in the period, Calvin confronted the problems left behind by Luther and endeavored to create his own universal church to supplant the Catholic Church. His theory of a new elite would have a distinct impact on history. By examining the political ideas that first emerged during the Renaissance and Reformation, this fascinating volume provides a foundation for understanding the events of centuries to follow.

Jones's (1991) issue-contingent model of ethical decision making posits that six dimensions of moral intensity influence decision markers' recognition of an issue as a moral problem and subsequent behavior. He notes that "organizational settings present special challenges to moral agents" (1991, p. 390) and that organizational factors affect "moral decision making and behavior at two points: establishing moral intent and engaging in moral behavior" (1991, p. 391). This model, however, minimizes both the impact of organizational setting and organizational factors on (...) these experiences of ethical issues. In this theory, context is modeled as affecting the moral intent and behavior of the actor rather than directly affecting the issue's moral intensity. Here we look specifically at the effect of context on the moral intensity of ethical issues through a phenomenological study. Our results indicate that in certain environments, context may be critical in affecting the moral intensity of ethical issues. Thus, researchers should consider it more fully when assessing these issues' moral intensity. (shrink)

_Explanation and Power _ was first published in 1988. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. The meaning of any utterance or any sign is the response to that utterance or sign: this is the fundamental proposition behind Morse Peckham's _Explanation and Power. Published_ in 1979 and now available in paperback for the first time, _Explanation and Power _grew out of Peckham's efforts, (...) as a scholar of Victorian literature, to understand the nature of Romanticism. His search ultimately led back to—and built upon—the tradition of signs developed by the American Pragmatists. Since, in Peckham's view, meaning is not inherent in word or sign, only in response, human behavior itself must depend upon interaction, which in turn relies upon the stability of verbal and nonverbal signs. In the end, meaning can be stabilized only by explanation, and when explanation fails, by force. Peckham's semiotic account of human behavior, radical in its time, contends with the same issues that animate today's debates in critical theory — how culture is produced, how meaning is arrived at, the relation of knowledge to power and of society to its institutions. Readers across a wide range of disciplines, in the humanities and social sciences, will welcome its reappearance. (shrink)

There is an extensive literature in social choice theory studying the consequences of weakening the assumptions of Arrow's Impossibility Theorem. Much of this literature suggests that there is no escape from Arrow-style impossibility theorems unless one drastically violates the Independence of Irrelevant Alternatives (IIA). In this paper, we present a more positive outlook. We propose a model of comparing candidates in elections, which we call the Advantage-Standard (AS) model. The requirement that a collective choice rule (CCR) be rationalizable by (...) the AS model is in the spirit of but weaker than IIA; yet it is stronger than what is known in the literature as weak IIA (two profiles alike on x, y cannot have opposite strict social preferences on x and y). In addition to motivating violations of IIA, the AS model makes intelligible violations of another Arrovian assumption: the negative transitivity of the strict social preference relation P. While previous literature shows that only weakening IIA to weak IIA or only weakening negative transitivity of P to acyclicity still leads to impossibility theorems, we show that jointly weakening IIA to AS rationalizability and weakening negative transitivity of P leads to no such impossibility theorems. Indeed, we show that several appealing CCRs are AS rationalizable, including even transitive CCRs. (shrink)

In this article, we develop a conceptual framework to understand how a company’s CSR identity becomes defined as a political activity destabilizing the strong identity–image relations. We draw on theories of political CSR and organizational identity–image relations to study how CSR emerges as a corporate political activity in a context where the corporate CSR work is first appreciated and later critiqued by the public in the wake of socio-political events. We analyse the micro-organizational processes in the context of macro-political level (...) changes, and we refer to this as the ‘identity–image dynamics of political CSR’. Concretely, we describe in two vignettes how IKEA’s declared ‘apolitical and neutral’ CSR identity becomes entangled with national and international socio-political events that critically challenge the corporate engagement prior national understandings of citizenship rights. In this process, IKEA’s CSR identity becomes defined as a political and non-neutral activity. Our article contributes by bringing attention to the organizational level dynamics of political CSR by offering a conceptualization of how global and local socio-political events may disturb the alignment between CSR identity and image and challenge the corporate CSR work beyond managerial control.

According to Cantor (Mathematische Annalen 21:545–586, 1883 ; Cantor’s letter to Dedekind, 1899 ) a set is any multitude which can be thought of as one (“jedes Viele, welches sich als Eines denken läßt”) without contradiction—a consistent multitude. Other multitudes are inconsistent or paradoxical. Set theoretical paradoxes have common root—lack of understanding why some multitudes are not sets. Why some multitudes of objects of thought cannot themselves be objects of thought? Moreover, it is a logical truth that such multitudes do (...) exist. However we do not understand this logical truth so well as we understand, for example, the logical truth $${\forall x \, x = x}$$ . In this paper we formulate a logical truth which we call the productivity principle. Rusell (Proc Lond Math Soc 4(2):29–53, 1906 ) was the first one to formulate this principle, but in a restricted form and with a different purpose. The principle explicates a logical mechanism that lies behind paradoxical multitudes, and is understandable as well as any simple logical truth. However, it does not explain the concept of set. It only sets logical bounds of the concept within the framework of the classical two valued $${\in}$$ -language. The principle behaves as a logical regulator of any theory we formulate to explain and describe sets. It provides tools to identify paradoxical classes inside the theory. We show how the known paradoxical classes follow from the productivity principle and how the principle gives us a uniform way to generate new paradoxical classes. In the case of ZFC set theory the productivity principle shows that the limitation of size principles are of a restrictive nature and that they do not explain which classes are sets. The productivity principle, as a logical regulator, can have a definite heuristic role in the development of a consistent set theory. We sketch such a theory—the cumulative cardinal theory of sets. The theory is based on the idea of cardinality of collecting objects into sets. Its development is guided by means of the productivity principle in such a way that its consistency seems plausible. Moreover, the theory inherits good properties from cardinal conception and from cumulative conception of sets. Because of the cardinality principle it can easily justify the replacement axiom, and because of the cumulative property it can easily justify the power set axiom and the union axiom. It would be possible to prove that the cumulative cardinal theory of sets is equivalent to the Morse–Kelley set theory. In this way we provide a natural and plausibly consistent axiomatization for the Morse–Kelley set theory. (shrink)

The article will argue that Charles Sanders Peirce's concepts of the ‘Dynamics of Belief and Doubt’, the ‘Fixation of Belief’ as well as ‘habits of belief’ taken together comprise a theory of learning. The ‘dynamics of belief and doubt’ are Peirce's explanation for the process of changing from one belief to another. Teaching, then, would be an attempt to control that process. Teaching critical thinking represents an attempt to teach the learner to regulate and discipline his or her own (...) ‘settlement of belief’. The ‘settlement of belief’ takes four different forms based on doubt. Peirce's concept of the ‘habits of belief’ refers to the inner and outer constraints placed both on belief as such and belief as it becomes action. The article may be read as both an exegesis of learning and as a pedagogical guide for teaching critical thinking to college students. (shrink)

In arguing against the view that the ethical standards for business are separate from normal interpersonal standards, virtue theory has been applied to business ethics in a limited manner. Previous virtue theorists have argued that this separation need not occur because the virtues for succeeding in business are congruent with civic and personal virtues. However, they have neglected the fact that virtue theory stresses that virtues are formed to fulfil certain desires, ends, and purposes of the person. Since (...) ends are formed within a community, business and corporations should view themselves as members of the community which contributes to the ethical development of its individuals. Hence, I argue that business cannot have a separate standard of ethical behaviour than that of its community, because its goals are means which are subordinate to the ultimate goal of individual and community flourishing.

This book presents a comprehensive overview of what the criminal law would look like if organised around the principle that those who deserve punishment should receive punishment commensurate with, but no greater than, that which they deserve. Larry Alexander and Kimberly Kessler Ferzan argue that desert is a function of the actor's culpability, and that culpability is a function of the risks of harm to protected interests that the actor believes he is imposing and his reasons for acting in the (...) face of those risks. The authors deny that resultant harms, as well as unperceived risks, affect the actor's desert. They thus reject punishment for inadvertent negligence as well as for intentions or preparatory acts that are not risky. Alexander and Ferzan discuss the reasons for imposing risks that negate or mitigate culpability, the individuation of crimes, and omissions. (shrink)

Amid all the talk about the "Collective Unconscious" and other sexy issues, most readers are likely to miss the fact that C.G. Jung was a good Kantian. His famous theory of Synchronicity, "an acausal connecting principle," is based on Kant 's distinction between phenomena and things-in-themselves and on Kant 's theory that causality will not operate among thing-in-themselves the way it does in phenomena. Thus, Kant could allow for free will among things-in-themselves, as Jung allows for synchronicity. Next (...) to Kant, Jung is close to. (shrink)

Using Jakob Fries's epistemological scheme of Wissen, Glaube, and Ahndung, "Understanding, Belief, and Aesthetic Sense," (to use Kent Richter's translation), Ruldolf Otto expands the meaning of Ahndung beyond the merely aesthetic by introducing the category of numinosity, which is the quality of sacred or holy objects, persons, or experiences in religion. Although Otto is often classified as a theoretician of mysticism, "numinosity" is not fundamentally a theory of mystical experiences, because every practionier of any religion experiences certain things as (...) sacred to that religion. The "sacred" and the "holy," and the "unclean" or "polluted," are categories that apply (non-metaphorically) to peculiarly religious objects in an entirely universal and cross-cultural manner.

Penrose's searching discussion in..

Most theories of learning would predict a gradual acquisition and refinement of skills as learning progresses, and while some highlight exponential growth, this fails to explain why natural cognitive development typically progresses in stages. Models that do span multiple developmental stages typically have parameters to “switch” between stages. We argue that by taking an embodied view, the interaction between learning mechanisms, the resulting behavior of the agent, and the opportunities for learning that the environment provides can account for the stage-wise (...) development of cognitive abilities. We summarize work relevant to this hypothesis and suggest two simple mechanisms that account for some developmental transitions: neural readiness focuses on changes in the neural substrate resulting from ongoing learning, and perceptual readiness focuses on the perceptual requirements for learning new tasks. Previous work has demonstrated these mechanisms in replications of a wide variety of infant language experiments, spanning multiple developmental stages. Here we piece this work together as a single model of ongoing learning with no parameter changes at all. The model, an instance of the Epigenetic Robotics Architecture embodied on the iCub humanoid robot, exhibits ongoing multi-stage development while learning pre-linguistic and then basic language skills.

Next SectionBiodefence, broadly understood as efforts to prevent or mitigate the damage of a bioterrorist attack, raises a number of ethical issues, from the allocation of scarce biomedical research and public health funds, to the use of coercion in quarantine and other containment measures in the event of an outbreak. In response to the US bioterrorist attacks following September 11, significant US policy decisions were made to spur scientific enquiry in the name of biodefence. These decisions led to a number (...) of critical institutional changes within the US federal government agencies governing scientific research. Subsequent science policy discussions have focused largely on ‘the dual use problem’: how to preserve the openness of scientific research while preventing research undertaken for the prevention or mitigation of biological threats from third parties. We join others in shifting the ethical debate over biodefence away from a simple framing of the problem as one of dual use, by demonstrating how a dual use framing distorts the debate about bioterrorism and truncates discussion of the moral issues. We offer an alternative framing rooted in social epistemology and institutional design theory, arguing that the ethical and policy debates regarding ‘dual use’ biomedical research ought to be reframed as a larger optimisation problem across a plurality of values including, among others: (1) the production of scientific knowledge; (2) the protection of human and animal subjects; (3) the promotion and protection of public health (national and global); (4) freedom of scientific enquiry; and (5) the constraint of government power.

There is a well-known equivalence between avoiding accuracy dominance and having probabilistically coherent credences (see, e.g., de Finetti 1974, Joyce 2009, Predd et al. 2009, Pettigrew 2016).

In this paper, I establish connections between accuracy dominance and coherence when credence functions are defined on an infinite set of propositions. In particular, I establish the necessary results to extend the classic accuracy (...) argument for probabilism to certain classes of infinite sets of propositions including countably infinite partitions.

Perhaps more than any other scholar, Michael Moore has argued that there are deep and necessary connections between metaphysics, morality, and law. Moore has developed every contour of a theory of criminal law, from philosophy of action to a theory of causation. Indeed, not only is he the central figure in retributive punishment but his moral realist position places him at the center of many jurisprudential debates. Comprised of essays by leading scholars, this volume discusses and challenges the (...) work of Michael Moore from one or more of the areas where he has made a lasting contribution, namely, law, morality, metaphysics, psychiatry, and neuroscience. The volume begins with a riveting contribution by Heidi Hurd, wherein she takes an unadorned and unabashed look at the man behind this monumental body of work, full of both triumphs and sadness. A number of essays focus on Moore's view of the purpose and justification of the criminal law, specifically his endorsement of retributivism and legal moralism. The book then addresses Moore's work in the various aspects of the general part of the criminal law, including Moore's position on how to understand criminal acts for double jeopardy purposes, Moore's claim that accomplice liability is superfluous, and Moore's views about the culpability of negligence, as well as the relationship between that view and proximate causation. Furthermore, the subject of defenses in criminal law is addressed, including self-defense, and also the intersection of psychiatry, psychology, cognitive neuroscience, and the criminal law. Also discussed are features of morality, and Moore's work in general jurisprudence. Finally, Moore concludes the volume with an essay that defends and delineates the features of his views. (shrink)

In Arrovian social choice theory assuming the independence of irrelevant alternatives, Murakami (1968) proved two theorems about complete and transitive collective choice rules that satisfy strict non-imposition (citizens’ sovereignty), one being a dichotomy theorem about Paretian or anti-Paretian rules and the other a dictator-or-inverse-dictator impossibility theorem without the Pareto principle. It has been claimed in the later literature that a theorem of Malawski and Zhou (1994) is a generalization of Murakami’s dichotomy theorem and that Wilson’s (1972) impossibility theorem is (...) stronger than Murakami’s impossibility theorem, both by virtue of replacing Murakami’s assumption of strict non-imposition with the assumptions of non-imposition and non-nullness. In this note, we first point out that these claims are incorrect: non-imposition and non-nullness are together equivalent to strict non-imposition for all transitive collective choice rules. We then generalize Murakami’s dichotomy and impossibility theorems to the setting of incomplete social preference. We prove that if one drops completeness from Murakami’s assumptions, his remaining assumptions imply (i) that a collective choice rule is either Paretian, anti-Paretian, or dis-Paretian (unanimous individual preference implies noncomparability) and (ii) that adding proposed constraints on noncomparability, such as the regularity axiom of Eliaz and Ok (2006), restores Murakami’s dictator-or-inverse-dictator result.

Dewey on The Emotions This paper explores John Dewey's theory of the emotions and his reasons for developing it. The author considers two competing accounts for why Dewey might have developed his theory: one based on his attempt to clarify rationality and one based on his attempt to make us morally responsive agents to nature. After a close examination of key texts, the author concludes that Dewey's theory is designed to make us morally responsive. Dewey's theory (...) of the emotions serves his purpose of arguing for our re-union with nature, in a manner similar, in fact, to Hegel, with the addition that Dewey makes it our express goal to be concerned for nature in our return to it.

What does a person really want when he asks for an apology? Why do people so often find it difficult to give an apology? Repentance is relevant to personal identity because the unrepentant soul has his own theory of personal identity. The unrepentant person believes he is his preference, and that he is entitled to the behavior that flows from those preferences. This fact can explain why people are so often reluctant to admit wrongdoing, why people place so much (...) importance upon receiving an apology and other behaviors that would be otherwise inexplicable. The unrepentant person uses something akin to a naive economic theory of human behavior. The naive version of homo economicus, or economic man, can never truly be sorry for anything, and as a result, will be almost impossible to live with. A person who identifies himself too closely with his preferences will bring misery to himself and those around him. (shrink)

How to respond justly to the dangers persistent violent offenders present is a vexing moral and legal issue. On the one hand, we wish to reduce predation; on the other, we want to treat predators fairly. The central theme of this paper is that it is difficult to achieve both goals without compromising one of them, and that both are being seriously undermined. I begin by explaining the legal theory, doctrine and practice governing dangerous offenders and demonstrate that the (...) law leaves a gap in the ability to confine them. Next I explore the means by which the law has overtly or covertly sought to fill the gap. Many of these measures, especially the new form of civil commitment for sexual predators, dangerously conflate moral and medical categories. I conclude that pure preventive detention is more common than we usually assume, but that this practice violates fundamental assumptions concerning liberty under the American constitutional regime.
