In this paper, we examine the relationship between general relativity and the theory of Einstein algebras. We show that according to a formal criterion for theoretical equivalence recently proposed by Halvorson and Weatherall, the two are equivalent theories.

Wilhelm (Forthcom Synth 199:6357–6369, 2021) has recently defended a criterion for comparing structure of mathematical objects, which he calls Subgroup. He argues that Subgroup is better than SYM \(^*\), another widely adopted criterion. We argue that this is mistaken; Subgroup is strictly worse than SYM \(^*\). We then formulate a new criterion that improves on both SYM \(^*\) and Subgroup, answering Wilhelm’s criticisms of SYM \(^*\) along the way. We conclude by arguing that no criterion that looks only to the (...) automorphisms of mathematical objects to compare their structure can be fully satisfactory. (shrink)

One of the most complex doctrines in contemporary international law, jus cogens is the immediate product of the socialization of the international community following the Second World War. However, the doctrine resonates in a centuries-old legal tradition which constrains the dynamics of voluntarism that characterize conventional international law. To reconcile this modern iteration of individual-oriented public order norms with the traditionally state-based form of international law, Thomas Weatherall applies the idea of a social contract to structure the analysis (...) of jus cogens into four areas: authority, sources, content and enforcement. The legal and political implications of this analysis give form to jus cogens as the product of interrelation across an individual-oriented normative framework, a state-based legal order, and values common to the international community as a whole.

One of us [Gilbert, M.. “Collective Belief and Scientific Change.” Sociality and Responsibility. Lanham, MD: Rowman & Littlefield. 37-49.] has proposed that ascriptions of beliefs to scientific communities generally involve a common notion of collective belief described by her in numerous places. A given collective belief involves a joint commitment of the parties, who thereby constitute what Gilbert refers to as a plural subject. Assuming that this interpretive hypothesis is correct, and that some of the belief ascriptions in question are (...) true, then the members of some scientific communities have obligations that may act as barriers both to the generation and, hence, the fair evaluation of new ideas and to changes in their community’s beliefs. We argue that this may help to explain Thomas Kuhn’s observations on “normal science”, and go on to develop the relationship between Gilbert's proposal and several features of a group of physicists working on a fundamental physical theory called “string theory”, as described by physicist Lee Smolin [Smolin, L.. The Trouble with Physics. Mariner Books: New York.]. We argue that the features of the string theory community that Smolin cites are well explained by the hypothesis that the community is a plural subject of belief. (shrink)

In this article, I examine whether or not the Hamiltonian and Lagrangian formulations of classical mechanics are equivalent theories. I do so by applying a standard for equivalence that was recently introduced into philosophy of science by Halvorson and Weatherall. This case study yields three general philosophical payoffs. The first concerns what a theory is, while the second and third concern how we should interpret what our physical theories say about the world. 1Introduction 2When Are Two Theories Equivalent? 3Preliminaries (...) on Classical Mechanics 3.1Hamiltonian mechanics 3.2Lagrangian mechanics 4Are Hamiltonian and Lagrangian Mechanics Equivalent Theories? 4.1Tangent bundle versus cotangent bundle 4.2Tangent bundle versus symplectic manifold 4.3Lagrangian vector field versus Hamiltonian vector field 5Conclusion Appendix.

In his paper, ‘Regarding the ‘Hole Argument”, Weatherall suggests that models of general relativity related by a hole diffeomorphism must be regarded as being physically equivalent. At a later stage in the paper, however, he also argues that there is a sense in which two such models may be regarded as being empirically distinct—a fortiori physically distinct. We attempt to delineate the logic behind these two prima facie contradictory claims. We argue that the latter sense rests upon a misunderstanding (...) of the import of shift arguments in the foundations of spacetime theories. (shrink)

Since the end of the Cold War, international ethicists have focused largely on issues outside the traditional scope of security studies. The nuclear ethics literature needs to be revived and reoriented to address the new and evolving 21st century nuclear threats and policy responses.

This article advances a critical analysis of John Rawls’s justification of liberal democratic nuclear deterrence in the post-Cold War era as found in The Law of Peoples. Rawls’s justification overlooked how nuclear-armed liberal democracies are ensnared in two intransigent ethical dilemmas: one in which the mandate to secure liberal constitutionalism requires both the preservation and violation of important constitutional provisions in domestic affairs, and the other in which this same mandate requires both the preservation and violation of the liberal commitment (...) to international legal arrangements and to the rule of law generally. On this view, the choice to violate constitutional provisions and international legal arrangements is evidence of nuclear despotism. Moreover, this choice does not imply that the ethical foreign policy dilemmas were resolved. Instead, it implies that the dilemmas force liberal democratic governments into implementing ethically paradoxical policy outcomes. (shrink)

This paper critically examines John Mark Mattox's view of the nature of the moral appropriateness of particular response options. By so doing, I aim to engage the wider readership in a debate, which I hope leads to greater clarity and precision of thinking on these topics. After summarizing Mattox's view, I argue first that in order for Mattox's ultimate conclusion to hold in moral terms, he must abandon the argument on the permissibility of nuclear reprisal to re-establish nuclear deterrence and (...) instead anchor this response solely on the moral grounds of retributive justice. Secondly, I argue that the morally superior and politically efficacious counter-nuclear terrorist response is to hunt down the nuclear terrorists and hold them accountable for war crimes in the International Criminal Court. This response is consistent with just war theoretic principles, and it also affirms the moral virtues of honor, dignity, and humane treatment in contexts where they are needed the most? the holocausts of nuclear terrorist attacks.

Biblical writers present a grand vision of the priestly vocation, in which the sacramental life of worship is translated into an ethical mission to the world. It is a vision in which the priestly vocation of the ordained in the sanctuary and the priestly vocation of the laity in the world work in concert to fulfill the divine vision of a transformed earth.1.

The hypothesis proposed by Macphail is that differences in intelligent behavior thought to distinguish different species were likely attributed to differences in the context of the tasks being used. Once one corrects for differences in sensory input, motor output, and incentive, it is likely that all vertebrate animals have comparable intellectual abilities. In the present article I suggest a number of tests of this hypothesis with pigeons. In each case, the evidence suggests that either there is evidence for the cognitive (...) behavior, or the pigeons suffer from biases similar to those of humans. Thus, Macphail’s hypothesis offers a challenge to researchers to find the appropriate conditions to bring out in the animal the cognitive ability being tested. (shrink)

Thomas Sattig develops a novel philosophical picture of ordinary objects such as persons, tables, and trees. He carves a middle way between classical mereology and Aristotelian hylomorphism, and argues that objects lead double lives. They are compounds of matter and form, and each object's matter and form have different qualitative profiles.

This series offers central philosophical treatises of Aquinas in new, state-of-the-art translations distinguished by their accuracy and use of clear and nontechnical modern vocabulary. Annotation and commentary accessible to undergraduates make the series an ideal vehicle for the study of Aquinas by readers approaching him from a variety of backgrounds and interests.

In the years since Enron corporate social responsibility, or “CSR,” has become a ubiquitous phenomenon in both research and business practice. CSR is used as an umbrella term to describe much of what is done in terms of ethics-related activities in firms around the globe to such an extent that some consider it a “tortured concept” (Godfrey and Hatch 2007, Journal of Business Ethics 70, 87–98). Addressing this skepticism, I argue in this article that the focus on CSR is indeed (...) problematic for three main reasons: (1) the term carries a lot of historical baggage – baggage that is not necessarily conducive to the clarity of the concept; (2) it is the object of increasing ethical instrumentalism; and (3) given the multiple ethical challenges that corporations face, and given the fact that the “social” responsibilities of business are but one set of corporate responsibilities, a suitable term would have to be more inclusive and integrative. I therefore suggests moving instead toward a sound definition of corporate integrity and aim in this article to develop a working definition by fleshing out “7 Cs” of integrity: commitment, conduct, content, context, consistency, coherence, and continuity. I then discuss how these 7 Cs impact our understanding of CSR or, more broadly, corporate responsibility in general. (shrink)

During the past ten years Integrative Social Contracts Theory (ISCT) has become part of the repertoire of specialized decision-oriented theories in the business ethics literature. The intention here is to (1)␣provide a brief overview of the structure and strengths of ISCT; (2) identify recurring themes in the extensive commentary on the theory including brief mention of how ISCT has been applied outside the business ethics literature; (3) describe where research appears to be headed; and (4) specify challenges faced by those (...) who seek to reform ISCT. Key themes in the critiquing literature relate to (a) the identification process for hypernorms; (b) justification of the recognition of hypernorms; (c) proposals for considering meso or meta norms; (d)␣clarification of the relationship between stakeholder concepts and ISCT; (e) problems with potentially unoccupied moral free space; (f) sources of ethical obligation within the ISCT framework; and (g) the potential role for concepts of stakeholder dialogue and engagement.

A new public philosophy began to emerge in the United States during the Progressive Era. Promoted by such intellectuals as John Dewey, William James, and the coUectivists of the New Republic magazine, it called for a citizenry trained in an experimental milieu, free of dogma and emancipated from sources of allegiance other than the new centralized democratic state then being forged. Catholics, however, neither capitulated to the new creed nor retreated into a self-righteous isolation. In a culture whose chief value (...) was pluralism they insisted on the uniqueness of the Church and the need for making value judgments based on a sound philosophy of man. (shrink)

Codes of ethics are directly aimed at behavioral control, but they also affect a company’s ethical culture, which in turn concerns compliance and ethical behavior. To positively influence a company’s ethical culture, employees must be familiar with its code of ethics, perceive that top management is committed to the code, and believe that their peers also comply with the code. The evidence on whether a code’s design affects a company’s ethical culture is limited. This study’s factorial survey experiment contributes to (...) this gap in two ways: first, it investigates whether a code’s design affects how easily the code can be learned and, therefore, contributes to code familiarity. Second, it examines how a code can convey expectations regarding top management’s commitment and peers’ behavior, both of which are part of ethical culture. The results indicate that a positive tone increases code familiarity, and a code signed by top managers sends a strong signal of their commitment to the code. Finally, various implications of the results for research and practice are discussed. (shrink)

Firms possessing a unique competency to rescue the victims of a human catastrophe have a minimum moral obligation to devote substantial resources toward best efforts to aid the victims. The minimum amount that firms should devote to rescue is the largest sum of their most recent year’s investment in social initiatives, their five-year trend, their industry’s average, or the national average. Financial exigency may justify a lower level of investment. Alternative social investments may be continued if they have an equally (...) compelling rationale. These duties apply to the global pharmaceutical companies in the context of the AIDS pandemic in sub-Saharan Africa. (shrink)

Quantum mechanics has provided philosophers of science with many counterintuitive insights and interpretive puzzles, but little has been written about the role that time plays in the theory. One reason for this is the celebrated argument of Wolfgang Pauli against the inclusion of time as an observable of the theory, which has been seen as a demonstration that time may only enter the theory as a classical parameter. Against this orthodoxy I argue that there are good reasons to expect certain (...) kinds of 'time observables' to find a representation within quantum theory, including clock operators and event time operators, which provide predictions for the time at which a particular event occurs, such as the appearance of a dot on a luminescent screen. I contend that these time operators deserve full status as observables of the theory, and on reflection provide a uniquely compelling reason to expand the set of observables allowed by the standard formalism of quantum mechanics. In addition, I provide a novel association of event time operators with conditional probabilities, and propose a temporally extended form of quantum theory to better accommodate the time of an event as an observable quantity. This leads to a proposal to interpret quantum theory within an event ontology, inspired by Bertrand Russell's Analysis of Matter. On this basis I mount a defense of Russell's relational theory of time against a recent attack. (shrink)

As phenomenology rose to prominence at the beginning of the 20th century, several aestheticians tried to establish the Husserlian method of “phenomenological reduction” in the field of aesthetics. These ventures were met with resistance from psychological aesthetics, which was the predominant form of aesthetics in the German-speaking world at the time. This paper examines, first, practical attempts to apply the method of “phenomenological reduction” in aesthetics. Using Waldemar Conrad and Moritz Geiger as examples, I try to trace what aestheticians actually (...) did when they applied this method in their investigations. Secondly, I reconstruct the four central objections with which psychological aesthetics reacted to such attempts. I have identified four central counterarguments in the work of Johannes Volkelt and Oswald Külpe, who were among the most eminent critics of phenomenological aesthetics: the transcendental argument, the susceptibility-to-errors argument, the constructivism argument, and the non-normativity argument. Finally, I also discuss the refusal of psychological aesthetics to acknowledge that a genuine phenomenological method even existed and the consequences of this refusal. (shrink)

Many of the problems studied in cognitive science are inductive problems, requiring people to evaluate hypotheses in the light of data. The key to solving these problems successfully is having the right inductive biases—assumptions about the world that make it possible to choose between hypotheses that are equally consistent with the observed data. This article explores a novel experimental method for identifying the biases that guide human inductive inferences. The idea behind this method is simple: This article uses the responses (...) produced by a participant on one trial to generate the stimuli that either they or another participant will see on the next. A formal analysis of this “iterated learning” procedure, based on the assumption that the learners are Bayesian agents, predicts that it should reveal the inductive biases of these learners, as expressed in a prior probability distribution over hypotheses. This article presents a series of experiments using stimuli based on a well-studied set of category structures, demonstrating that iterated learning can be used to reveal the inductive biases of human learners.

Abstractabstract:There are two ways of hearing Philo's unexpected endorsement of a version of the design hypothesis in the final part of Hume's Dialogues. We might register it in accordance with Cleanthes's descriptivist approach to religious speech, taking Philo to be reasoning with Cleanthes in Cleanthes's own way. Or we might hear Philo's words in accordance with his own expressivist account of religious speech, an account that Philo appears to have borrowed from Hobbes. I argue that Hume intended this double layering (...) of meanings, presenting us with two distinct ways we might understand Philo's closing remarks. Each possible reading reveals a distinct Humean lesson about the limitations of natural theology. (shrink)

The article focuses on the ability of some animals and plants to respond to changing environmental conditions by temporarily suspending metabolic processes. In contemporary biology, this state between life and death is commonly labelled ‘cryptobiosis’, combining the Greek kryptos (hidden, concealed, secret) with biōsis (mode of life). I argue that the notion of ‘cryptobiosis’ does not account sufficiently for the processual and relational dimensions of ametabolic life. The article advances a related but different concept, which better addresses this liminal state (...) of biological organisation: s uspended life. While cryptobiosis still nurtures the imaginary of some latent life, suspended life stresses the liminality of the neither-nor life and death. The notion also grasps the dynamic and ongoing transfer between the biological and the technological. While the debate on cryptobiosis has so far remained confined to the description of natural processes, suspended life (or limbiosis) promises to account for contemporary technological practices of cryopreservation.

Scotus is notorious for occasionally making statements that, on their face at least, smack of voluntarism, but there has been a lively debate about whether Scotus is really a voluntarist after all. Now the debate is not over whether Scotus lays great emphasis on the role of the divine will with respect to the moral law. No one could sensibly deny that he does, and if such an emphasis constitutes voluntarism, then no one could sensibly deny that Scotus is a (...) voluntarist. As I am using the word, however, voluntarism is the view that (i) the goodness of almost all things, as well as the rightness of almost all acts, depends wholly on the divine will and (ii) what God wills with respect to those things and those acts is not in turn to be explained by reference to the divine intellect, human nature, or anything else. This is the view that Scotus’s critics decry and his defenders disclaim. Thus, his critics have seized on these passages and accused Scotus of believing that the moral law depends simply on “the arbitrary will of God.” His most sympathetic interpreters, however, have devoted great ingenuity to showing that Scotus did not mean anything unpalatable by these statements.1 What the critics and defenders apparently have in common is the view that voluntarism is an implausible and even discreditable doctrine. Interpreters who read Scotus as a voluntarist intend thereby to damn his moral views; interpreters sympathetic to his moral views feel compelled to mitigate his voluntarism. I wish to argue for a different approach. I agree with his defenders that Scotus’s moral philosophy ought to be taken seriously. But I think the best way to take any philosopher’s view seriously is to let him speak for himself, not to decide in advance that he must not have held a view that we find implausible. Let me suggest an analogy that will make my position clearer. Very nearly everyone finds immaterialism implausible. (shrink)
