Metaphysics-first approaches dominate the current literature in the epistemology of modality. According to metaphysics-firsters, metaphysical theses have an important role in the justification of modal epistemologies. For example, the thesis that essentialist truths constitute the metaphysical grounds of modal truths is meant to have an important role in the justification of essentialist modal epistemologies. In this article, we argue against this approach. We first pick up some of the groundwork on behalf of the metaphysics-firsters and explicitly spell out potential arguments (...) for their view. However, despite some initial plausibility, these arguments are ultimately found wanting. We conclude that the metaphysics-first approach lacks motivation and puts far too stringent demands upon modal epistemologists. (shrink)

BackgroundThe values and attitudes of healthcare professionals influence their handling of ‘do-not-attempt-resuscitation’ (DNAR) orders. The aim of this study was a) to describe attitudes, perceptions and practices among Swedish physicians and nurses towards discussing cardiopulmonary resuscitation and DNAR orders with patients and their relatives, and b) to investigate if the physicians and nurses were familiar with the national ethical guidelines for cardiopulmonary resuscitation.MethodsThis was a retrospective observational study based on a questionnaire and was conducted at 19 wards in two regional (...) hospitals and one county hospital.Results210 physicians and 312 nurses (n = 522) responded to the questionnaire. Every third (35%) professional had read the guidelines with a lower proportion of physicians (29%) compared to nurses (38%). Around 40% of patients had the opportunity or ability to participate in the DNAR discussion. The DNAR decision was discussed with 38% of patients and the prognosis with 46%. Of the patients who were considered to have the ability to participate in the discussion, 79% did so. The majority (81%) of physicians and nurses believed that patients should always be asked about their preferences before a DNAR decision was made.ConclusionsSwedish healthcare professionals take a patient’s autonomy into account regarding DNAR decisions. Nevertheless, as 50% of patients were considered unable to participate in the DNAR discussion, questions remain about the timing of patient participation and whether more discussions could have been conducted earlier. Given the uncertainty about timing, the majority of patients deemed competent participated in DNAR discussions. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Taming the Leviathan: The Reception of the Political and Religious Ideas of Thomas Hobbes in England 1640–1700A. P. MartinichJon Parkin. Taming the Leviathan: The Reception of the Political and Religious Ideas of Thomas Hobbes in England 1640–1700. Ideas in Context, 82. Cambridge-New York: Cambridge University Press, 2007. Pp. xi + 449. Cloth, $115.Parkin’s book covers the same period and much of the same material as John Bowle’s Hobbes (...) and his Critics (1951) and Samuel Mintz’s The Hunting of Leviathan (1962), but his scholarship is more extensive and significantly better than that of the earlier books. The scholarship is similar to that of Jeffrey Collins in Hobbes’s Allegiance and belongs to the same school of Cambridge contextualism. Parkin’s book contains good summaries of the books and pamphlets that were published about Hobbes’ political and religious philosophy from 1640 until 1700. While much of this material is known to Hobbes scholars, Parkin has discovered or brought into play a large number of other works. It is good to have all of this material discussed in one place.The book contains, in addition to an Introduction and Conclusion, seven chapters: 1. Reading Hobbes before Leviathan (1640–1651); 2. Leviathan (1651–1654); 3. The Storm (1654–1658); 4. Restoration (1658–1666); 5. Hobbes and Hobbism (1666–1675); [End Page 142] 6. Hobbes and the Restoration Crisis (1675–1685); and 7. Hobbes in the Glorious Revolution (1685–1700).Parkin’s explications of the arguments of Hobbes’ contemporaries, his judgments about their criticisms of Hobbes, and the nature of Hobbes’ own work are too often unsuccessful. He usually does not discuss the structures of the arguments at all, as if narrative is incompatible with analysis, and he often uses tendentious language where argumentation is needed. Parkin uncritically uses “success” words where a hedged phrase is needed. It is quite doubtful that “[Samuel] Ward showed that reason and philosophy” did not subvert “traditional natural ethics” (167; my italics) rather than only trying or purporting to show that. Also, Parkin rarely notices that Hobbes’ critics often misunderstood him. For example, they all think that Hobbes claims that the whole world was in the state of nature at one time. Parkin gives little or no indication that he understands that the state of nature is primarily a concept in a thought experiment (167). The primary lesson of the reception of Hobbes’ philosophy between 1640 and 1700 was that his critics thoroughly misunderstood it, but Parkin ultimately does not appreciate it (e.g., 411; cf. 2, 5, 9). Some critics thought that Hobbes was a republican. There is good evidence that some of his critics never read Hobbes. William Sherlock, for example, writing after the Glorious Revolution, rejects Hobbes’ imagined de facto-ism to embrace a supposedly non-Hobbesian consent theory. In the 1690s, Hobbes the atheist was a convenient bogy. Ironies abound. The nonjurors who railed against Hob-bes, now over a decade dead, and deplored the Toleration Act, were in fact supporting his preference for a strong national church. A good book could be written with the title From Hobbes to Hobbism (cf. 3–4). Parkin does not emphasize that Hobbes’ critics “often absorbed his ideas at the same time as they attacked him” (412).As for his interpretation of Hobbes’ philosophy, Parkin seems uncritically to accept the interpretations of Quentin Skinner, even where they are fairly obviously mistaken. For example, following some of Skinner’s early essays on Hobbes, Parkin says that Leviathan defended de facto theory (193), although later in the book, he seems not to accept this position (e.g., 362, 373). What Skinner ignored is a central feature of Hobbes’ philosophy, namely that no obligation is incurred except through some act of one’s own. This feature is incompatible with a central feature of de facto theory, namely, that a government is legitimate when it has the power to coerce. Parkin thinks that consent theory is a form of de facto theory (387, 412). Even Skinner in his collected essays, Visions of Politics, has backed off somewhat from his earlier view.Parkin writes, “One of the aims of this study has been... (shrink)

Discussions of sexual ethics often focus on the wrong of treating another as a mere object instead of as a person worthy of respect. On this view, the task of sexual ethics becomes putting the other’s subjectivity above their status as erotic object so as to avoid the harms of objectification. Ward and Anderson argue that such a view disregards the crucial, moral role that erotic objecthood plays in sexual encounters. Important moral features of intimacy are disclosed through the (...) experience of being an erotic object for another, as well as in perceiving another as an erotic object. Drawing on phenomenology, especially the insights of Simone de Beauvoir, Ward and Anderson argue that erotic encounters are shaped by the human condition of ambiguity, where being an object for others is intertwined with bodily agency. Because sexual agency is complex in this way, theories of sexual ethics and responsibility must widen their focus beyond transparent communication and authoritative expressions of will. (shrink)

According to Aristotle, the medical art aims at health, which is a virtue of the body, and does so in an unlimited way. Consequently, medicine does not determine the extent to which health should be pursued, and “mental health” falls under medicine only via pros hen predication. Because medicine is inherently oriented to its end, it produces health in accordance with its nature and disease contrary to its nature—even when disease is good for the patient. Aristotle’s politician understands that this (...) inherent orientation can be systematically distorted, and so would see the need for something like the Hippocratic Oath. (shrink)

Stephen Ward argues that present media practices are narrowly based within the borders of single country and thus unable to successfully inform the public about a globalized world. Presenting an ethical framework for work in multimedia, the author extends John Rawl’s theories of justice and the human good to redefine the aims for which journalism should strive and then applies this new foundation to issues such as the roles of patriotism and objectivity in journalism. An innovative argument that presents (...) a necessary corrective to contemporary media practices, Global Journalism Ethics is a theoretically rich study for journalists on the air, in print, and on the internet.

Building Better Health Care Leadership for Canada explains the development and implementation of the Executive Training in Research Application program. Managed and funded by the Canadian Health Services Research Foundation in partnership with the Canadian Medical Association, the Canadian Nursing Association, and the Canadian College of Health Care executives, EXTRA is a two-year national fellowship program that uses the principles of adult learning theory as well as practical projects to educate senior health care leaders in making more consistent use of (...) research evidence in their management roles. Fellows apply the theory learned in residency sessions and educational activities to projects within their home organizations. The authors identify the imperative for better use of evidence, outline the core elements of the curriculum, and capture the real-world experience of regional leaders and fellows involved in making specific changes informed by research-based evidence within their organization.

Julie K. Ward examines Aristotle's thought regarding how language informs our views of what is real. First she places Aristotle's theory in its historical and philosophical contexts in relation to Plato and Speusippus. Ward then explores Aristotle's theory of language as it is deployed in several works, including Ethics, Topics, Physics, and Metaphysics, so as to consider its relation to dialectical practice and scientific explanation as Aristotle conceived it.

Ward examines Scotus's arguments for his distinctive version of hylomorphism, the view that at least some material objects are composites of matter and form. It considers Scotus's reasons for adopting hylomorphism, and his accounts of how matter and form compose a substance, how extended parts, such as the organs of an organism, compose a substance, and how other sorts of things, such as the four chemical elements and all the things in the world, fail to compose a substance. It (...) highlights the extent to which Scotus draws on his metaphysics of essential order to explain why some things can compose substance and why others cannot. Throughout the book, contemporary versions of hylomorphism are discussed in ways that both illumine Scotus's own views and suggest ways to advance contemporary debates. (shrink)

In recent scholarship, the science and religion debate has been historicized, revealing the novelty of the concepts of science and religion and their complex connections to secularization and the birth of modernity. This article situates this historicist turn in the history of philosophy and its connections to theology and Scripture, showing that the science and religion concept derives from philosophy's earlier tension with theology as it became an academic discipline centered in the medieval, then research university, with the centrality of (...) Scripture changing under the influence of historical criticism. Looking at Thomas Aquinas and Friedrich Schleiermacher on theology and Scripture's connection to science, it offers a new framework for theorizing science and religion as part of the history of philosophy.

This study examines how news factors in press releases influence journalists’ decisions and the journalistic treatment of press release information after its initial selection for the news agenda: These journalists can transform press releases into a news story, which involves little journalistic capital investment, or use these releases for a unique news production, which requires significant journalistic capital investment. The data elicited from the content analysis show that the more profound the presence of certain news factors in press releases, the (...) higher the chance that journalists will choose to invest their journalistic capital in these press releases. This result means that journalists will only invest journalistic capital in press releases that contain specific news factors. (shrink)

Can an AGI create a more intelligent AGI? Under idealized assumptions, for a certain theoretical type of intelligence, our answer is: “Not without outside help”. This is a paper on the mathematical structure of AGI populations when parent AGIs create child AGIs. We argue that such populations satisfy a certain biological law. Motivated by observations of sexual reproduction in seemingly-asexual species, the Knight-Darwin Law states that it is impossible for one organism to asexually produce another, which asexually produces another, and (...) so on forever: that any sequence of organisms (each one a child of the previous) must contain occasional multi-parent organisms, or must terminate. By proving that a certain measure (arguably an intelligence measure) decreases when an idealized parent AGI single-handedly creates a child AGI, we argue that a similar Law holds for AGIs. (shrink)

BackgroundInformal mHealth is widely used by community health nurses in Ghana to extend healthcare delivery services to clients who otherwise might have been excluded from formal health systems or would experience significant barriers in their quest to access formal health services. The nurses use their private mobile phones or devices to make calls to their clients, health volunteers, colleagues or superiors. These phone calls are also reciprocal in nature. Besides, the parties exchange or share other health data and information through (...) text messages, pictures, videos or voice clips. There are some ethical dimensions that are inherent in these practices that ought to be critically scrutinised by bioethicists.ObjectiveThe author has argued in this paper that informal mHealth at large scale adoption in Ghana is associated with some bioethical challenges.MethodsThis essay was largely based on an analysis of an empirical study published by Hampshire et al in 2021 on the use of informal mHealth methods in Ghana.ResultsWidespread adoption of Informal mHealth in Ghana is associated with privacy invasion of both the nurses and their clients, breaches confidentiality of the parties, discredits the validity of informed consent processes and may predispose the nurses to some other significant aggregated harms.ConclusionThe author affirms his partial support for a formalised adoption process of informal mHealth in Ghana but has reiterated that the current ethical challenges associated with informal mHealth in Ghana cannot escape all the debilitating bioethical challenges, even if it is formalised.

Legg and Hutter, as well as subsequent authors, considered intelligent agents through the lens of interaction with reward-giving environments, attempting to assign numeric intelligence measures to such agents, with the guiding principle that a more intelligent agent should gain higher rewards from environments in some aggregate sense. In this paper, we consider a related question: rather than measure numeric intelligence of one Legg- Hutter agent, how can we compare the relative intelligence of two Legg-Hutter agents? We propose an elegant answer (...) based on the following insight: we can view Legg-Hutter agents as candidates in an election, whose voters are environments, letting each environment vote (via its rewards) which agent (if either) is more intelligent. This leads to an abstract family of comparators simple enough that we can prove some structural theorems about them. It is an open question whether these structural theorems apply to more practical intelligence measures. (shrink)

We define a notion of the intelligence level of an idealized mechanical knowing agent. This is motivated by efforts within artificial intelligence research to define real-number intelligence levels of compli- cated intelligent systems. Our agents are more idealized, which allows us to define a much simpler measure of intelligence level for them. In short, we define the intelligence level of a mechanical knowing agent to be the supremum of the computable ordinals that have codes the agent knows to be codes (...) of computable ordinals. We prove that if one agent knows certain things about another agent, then the former necessarily has a higher intelligence level than the latter. This allows our intelligence no- tion to serve as a stepping stone to obtain results which, by themselves, are not stated in terms of our intelligence notion (results of potential in- terest even to readers totally skeptical that our notion correctly captures intelligence). As an application, we argue that these results comprise evidence against the possibility of intelligence explosion (that is, the no- tion that sufficiently intelligent machines will eventually be capable of designing even more intelligent machines, which can then design even more intelligent machines, and so on).

In Nicomachean Ethics 1. 7, Aristotle gives a definition of the human good, and he does so by means of the “ ergon argument.” I clear the way for a new interpretation of this argument by arguing that Aristotle does not think that the ergon of something is always the proper activity of that thing. Though he has a single concept of an ergon, Aristotle identifies the ergon of an X as an activity in some cases but a product in (...) others, depending on the sort of thing the X is—for while the ergon of the eye is seeing, the ergon of a sculptor is a sculpture. This alternative interpretation of Aristotle’s concept of an ergon allows the key explanatory middle term of the ergon argument to be what, I argue, it ought to be: “the best achievement of a human.”.

This book is a comprehensive introduction to media ethics and an exploration of how it must change to adapt to today's media revolution. Using an ethical framework for the new 'mixed media' ethics – taking in the global, interactive media produced by both citizens and professionals – Stephen J. A. Ward discusses the ethical issues which occur in both mainstream and non-mainstream media, from newspapers and broadcast to social media users and bloggers. He re-defines traditional conceptions of journalistic truth-seeking, (...) objectivity and minimizing harm, and examines the responsible use of images in an image-saturated public sphere. He also draws the contours of a future media ethics for the 'new mainstream media' and puts forward cosmopolitan principles for a global media ethics. His book will be invaluable for all students of media and for others who are interested in media ethics. (shrink)

Can an agent's intelligence level be negative? We extend the Legg-Hutter agent-environment framework to include punishments and argue for an affirmative answer to that question. We show that if the background encodings and Universal Turing Machine (UTM) admit certain Kolmogorov complexity symmetries, then the resulting Legg-Hutter intelligence measure is symmetric about the origin. In particular, this implies reward-ignoring agents have Legg-Hutter intelligence 0 according to such UTMs.

Why do public philosophy in prisons? When we think about the value and aims of public philosophy there is a well-entrenched tendency to think in transactional terms. The academy has something of value that it aims to pass on or transmit to its clients. Usually, this transaction takes place within the confines of the university, in the form of transmission of valuable skills or knowledge passed from faculty to students. Public philosophy, construed within this transactional mindset, then consists in passing (...) on something valuable from inside the academy to the outside. In this paper, we reflect on our experiences of taking philosophy into prisons and argue that making the case for public philosophy in general, and philosophy in prisons in particular in these transactional terms risks obscuring what we take to be a distinctive and valuable outcome of public philosophy. Importantly, it risks obscuring what those who participate in a particular kind of public philosophy – including the professional philosophers – experience as valuable about the activity: its transformational potential.

I argue that Spinoza endorses "conceptual dependence monism," the thesis that all forms of metaphysical dependence (such as causation, inherence, and existential dependence) are conceptual in kind. In the course of explaining the view, I further argue that it is actually presupposed in the proof for his more famed substance monism. Conceptual dependence monism also illuminates several of Spinoza’s most striking metaphysical views, including the intensionality of causal contexts, parallelism, metaphysical perfection, and explanatory rationalism. I also argue that this priority (...) of the conceptual does not commit Spinoza to forms of idealism or mentalism. The question of how to understand different kinds of metaphysical dependence is quite controversial in Spinoza studies; I address major alternative readings in the notes. But there I also try to draw connections to the growing debate in contemporary discussions about metaphysical dependence, as this topic is a happy point of shared interest between Spinoza and contemporary metaphysicians alike.

: This article argues that Kant’s doctrine of radical evil and the doctrine of conversion which is its consequent reflect developments in Kant’s thinking about moral agency and his realization that his theory of freedom was inadequate to the problem of moral evil; that the changes Kant makes to accommodate evil result in a significant though subterranean shift in his concept of agency, resulting in two incompatible concepts, one explicit but inadequate, the other implicit yet necessary; and that the problems (...) Kant encounters with radical evil and conversion and the concept of agency they push him towards provide an important link between Kant and German Idealism. (shrink)

We present a game mechanic called pseudo-visibility for games inhabited by non-player characters (NPCs) driven by reinforcement learning (RL). NPCs are incentivized to pretend they cannot see pseudo-visible players: the training environment simulates an NPC to determine how the NPC would act if the pseudo-visible player were invisible, and penalizes the NPC for acting differently. NPCs are thereby trained to selectively ignore pseudo-visible players, except when they judge that the reaction penalty is an acceptable tradeoff (e.g., a guard might accept (...) the penalty in order to protect a treasure because losing the treasure would hurt even more). We describe an RL agent transformation which allows RL agents that would not otherwise do so to perform some limited self-reflection to learn the training environments in question. (shrink)

After generalizing the Archimedean property of real numbers in such a way as to make it adaptable to non-numeric structures, we demonstrate that the real numbers cannot be used to accurately measure non-Archimedean structures. We argue that, since an agent with Artificial General Intelligence (AGI) should have no problem engaging in tasks that inherently involve non-Archimedean rewards, and since traditional reinforcement learning rewards are real numbers, therefore traditional reinforcement learning probably will not lead to AGI. We indicate two possible ways (...) traditional reinforcement learning could be altered to remove this roadblock. (shrink)

The concept of the 'social Trinity', which posits three conscious subjects in God, radically revised the traditional Christian idea of the Creator. It promoted a view of God as a passionate, creative and responsive source of all being. Keith Ward argues that social Trinitarian thinking threatens the unity of God, however, and that this new view of God does not require a 'social' component. Expanding on the work of theologians such as Barth and Rahner, who insisted that there was (...) only one mind of God, Ward offers a coherent, wholly monotheistic interpretation of the Trinity. Christ and the Cosmos analyses theistic belief in a scientific context, demonstrating the necessity of cosmology to theological thinking that is often overly myopic and anthropomorphic. This important volume will benefit those who seek to understand what the Trinity is, why it matters and how it fits into a scientific account of the universe. (shrink)

This survey outlines a history of museums written through biographies of objects in their collections. First, the mechanics of the movement of things and the accompanying shifts in status are considered, from manufacture or growth through collecting and exchange to the museum. Objects gathered meanings through associations with people they encountered on their way to the collection, thus linking the history of museums to broader scientific and civic cultures. Next, the essay addresses the use of items once they joined a (...) collection, whether classificatory, analytical, or in display. By thus embedding the study of scientific practice in material culture, this approach contributes to constructivist histories of science. The final section addresses the role of objects in the experience of the visitors, emphasizing how fruitful the history of museum objects can be in the study of the public engagement with science.

Continuing Keith Ward's series on comparative religion, this book deals with religious views of human nature and destiny. The beliefs of six major traditions are presented: the view of Advaita Vedanta that there is one Supreme Self, unfolding into the illusion of individual existence; the Vaishnava belief that there is an infinite number of souls, whose destiny is to be released from material embodiment; the Buddhist view that there is no eternal Self; the Abrahamic belief that persons are essentially (...) embodied souls; and the materialistic position that persons are complex material organisms. Indian ideas of rebirth, karma, and liberation from samsara are critically analysed and compared with semitic belief in the intermediate state of Sheol, Purgatory or Paradise, the Final Judgement and the resurrection of the body. The impact of scientific theories of cosmic and biological evolution on religious beliefs is assessed, and a form of 'soft emergent materialism' is defended, with regard to the soul. In this context, a Christian doctrine of original sin and atonement is presented, stressing the idea of soterial, as opposed to forensic, justice. Finally, a Christian view of personal immortality and the 'end of all things' is developed in conversation with Jewish and Muslim beliefs about judgement and resurrection. (shrink)

Scholars have often thought that a monistic reading of Aristotle’s definition of the human good – in particular, one on which “best and most teleios virtue” refers to theoretical wisdom – cannot follow from the premises of the ergon argument. I explain how a monistic reading can follow from the premises, and I argue that this interpretation gives the correct rationale for Aristotle’s definition. I then explain that even though the best and most teleios virtue must be a single virtue, (...) that virtue could in principle be a whole virtue that arises from the combination of all the others. I also clarify that the definition of the human good aims at capturing the nature of human eudaimonia only in its primary case. (shrink)

We construct a machine that knows its own code, at the price of not knowing its own factivity.

In 2011, Hibbard suggested an intelligence measure for agents who compete in an adversarial sequence prediction game. We argue that Hibbard’s idea should actually be considered as two separate ideas: first, that the intelligence of such agents can be measured based on the growth rates of the runtimes of the competitors that they defeat; and second, one specific (somewhat arbitrary) method for measuring said growth rates. Whereas Hibbard’s intelligence measure is based on the latter growth-rate-measuring method, we survey other methods (...) for measuring function growth rates, and exhibit the resulting Hibbard-like intelligence measures and taxonomies. Of particular interest, we obtain intelligence taxonomies based on Big-O and Big-Theta notation systems, which taxonomies are novel in that they challenge conventional notions of what an intelligence measure should look like. We discuss how intelligence measurement of sequence predictors can indirectly serve as intelligence measurement for agents with Artificial General Intelligence (AGIs). (shrink)

A fundamental question asked in modal logic is whether a given theory is consistent. But consistent with what? A typical way to address this question identifies a choice of background knowledge axioms (say, S4, D, etc.) and then shows the assumptions codified by the theory in question to be consistent with those background axioms. But determining the specific choice and division of background axioms is, at least sometimes, little more than tradition. This paper introduces generic theories for propositional modal logic (...) to address consistency results in a more robust way. As building blocks for background knowledge, generic theories provide a standard for categorical determinations of consistency. We argue that the results and methods of this paper help to elucidate problems in epistemology and enjoy sufficient scope and power to have purchase on problems bearing on modalities in judgement, inference, and decision making.

One shortcoming of the chain rule is that it does not iterate: it gives the derivative of f(g(x)), but not (directly) the second or higher-order derivatives. We present iterated differentials and a version of the multivariable chain rule which iterates to any desired level of derivative. We first present this material informally, and later discuss how to make it rigorous (a discussion which touches on formal foundations of calculus). We also suggest a finite calculus chain rule (contrary to Graham, Knuth (...) and Patashnik's claim that "there's no corresponding chain rule of finite calculus"). (shrink)

We study the structure of families of theories in the language of arithmetic extended to allow these families to refer to one another and to themselves. If a theory contains schemata expressing its own truth and expressing a specific Turing index for itself, and contains some other mild axioms, then that theory is untrue. We exhibit some families of true self-referential theories that barely avoid this forbidden pattern.

We propose that, for the purpose of studying theoretical properties of the knowledge of an agent with Artificial General Intelligence (that is, the knowledge of an AGI), a pragmatic way to define such an agent’s knowledge (restricted to the language of Epistemic Arithmetic, or EA) is as follows. We declare an AGI to know an EA-statement φ if and only if that AGI would include φ in the resulting enumeration if that AGI were commanded: “Enumerate all the EA-sentences which you (...) know.” This definition is non-circular because an AGI, being capable of practical English communication, is capable of understanding the everyday English word “know” independently of how any philosopher formally defines knowledge; we elaborate further on the non-circularity of this circular-looking definition. This elegantly solves the problem that different AGIs may have different internal knowledge definitions and yet we want to study knowledge of AGIs in general, without having to study different AGIs separately just because they have separate internal knowledge definitions. Finally, we suggest how this definition of AGI knowledge can be used as a bridge which could allow the AGI research community to import certain abstract results about mechanical knowing agents from mathematical logic.

Inspired by recent progress in multi-agent Reinforcement Learning (RL), in this work we examine the collective intelligent behaviour of theoretical universal agents by introducing a weighted mixture operation. Given a weighted set of agents, their weighted mixture is a new agent whose expected total reward in any environment is the corresponding weighted average of the original agents' expected total rewards in that environment. Thus, if RL agent intelligence is quantified in terms of performance across environments, the weighted mixture's intelligence is (...) the weighted average of the original agents' intelligences. This operation enables various interesting new theorems that shed light on the geometry of RL agent intelligence, namely: results about symmetries, convex agent-sets, and local extrema. We also show that any RL agent intelligence measure based on average performance across environments, subject to certain weak technical conditions, is identical (up to a constant factor) to performance within a single environment dependent on said intelligence measure.

This article articulates a fundamental crisis of disciplinary philosophy—its lack of disciplinary self-consciousness and the skeptical problems this generates—and, through that articulation, exemplifies a means of mitigating its force. Disciplinary philosophy organizes itself as a producer of specialized knowledge, with the apparatus of journals, publication requirements, and other professional standards, but it cannot agree on what constitutes knowledge, progress, or value, and evinces ignorance of its history and alternatives. This situation engenders a skepticism that threatens the legitimacy of disciplinary philosophy. (...) The article proposes a response to this skepticism, rooted in the conditions that philosophers evince a specific kind of awareness of their own activity and its professional and cultural location, demonstrate this awareness by articulating it in the practice of philosophy itself, and recognize that precisely such articulation lies at the core of the Socratic idea of philosophy as a form of self-knowledge.

This chapter surveys the fate of Carl Schmitt’s concept of the political in twentieth-century European thought. It starts with the main outlines of his founding text The Concept of the Political, with emphasis on conceptual ambiguities in Schmitt’s argumentation that others would identify and exploit.

Culminating in Claude Lefort, this tradition decentered the role of enmity that Schmitt wanted to define the political, a point dramatized in conclusion with discussion of international relations theory and how the French tradition conceived of warfare and strife.
