Causal reasoning and game-theoretic reasoning are fundamental topics in artificial intelligence, among many other disciplines: this paper is concerned with their intersection. Despite their importance, a formal framework that supports both these forms of reasoning has, until now, been lacking. We offer a solution in the form of (structural) causal games, which can be seen as extending Pearl's causal hierarchy to the game-theoretic domain, or as extending Koller and Milch's multi-agent influence diagrams to the causal domain. We then consider three (...) key questions: i) How can the (causal) dependencies in games - either between variables, or between strategies - be modelled in a uniform, principled manner? ii) How may causal queries be computed in causal games, and what assumptions does this require? iii) How do causal games compare to existing formalisms? To address question i), we introduce mechanised games, which encode dependencies between agents' decision rules and the distributions governing the game. In response to question ii), we present definitions of predictions, interventions, and counterfactuals, and discuss the assumptions required for each. Regarding question iii), we describe correspondences between causal games and other formalisms, and explain how causal games can be used to answer queries that other causal or game-theoretic models do not support. Finally, we highlight possible applications of causal games, aided by an extensive open-source Python library. (shrink)

Can humans get arbitrarily capable reinforcement learning agents to do their bidding? Or will sufficiently capable RL agents always find ways to bypass their intended objectives by shortcutting their reward signal? This question impacts how far RL can be scaled, and whether alternative paradigms must be developed in order to build safe artificial general intelligence. In this paper, we study when an RL agent has an instrumental goal to tamper with its reward process, and describe design principles that prevent instrumental (...) goals for two different types of reward tampering. Combined, the design principles can prevent reward tampering from being an instrumental goal. The analysis benefits from causal influence diagrams to provide intuitive yet precise formalizations.

In this paper, we provide a detailed review of previous classifications of 2 × 2 games and suggest a mathematically simple way to classify the symmetric 2 × 2 games based on a decomposition of the payoff matrix into a cooperative and a zero-sum part. We argue that differences in the interaction between the parts is what makes games interesting in different ways. Our claim is supported by evolutionary computer experiments and findings in previous literature. In addition, we provide a (...) method for using a stereographic projection to create a compact 2-d representation of the game space. (shrink)

Causal models of agents have been used to analyse the safety aspects of machine learning systems. But identifying agents is non-trivial -- often the causal model is just assumed by the modeler without much justification -- and modelling failures can lead to mistakes in the safety analysis. This paper proposes the first formal causal definition of agents -- roughly that agents are systems that would adapt their policy if their actions influenced the world in a different way. From this we (...) derive the first causal discovery algorithm for discovering agents from empirical data, and give algorithms for translating between causal models and game-theoretic influence diagrams. We demonstrate our approach by resolving some previous confusions caused by incorrect causal modelling of agents. (shrink)

Externalist theories hold that a comprehensive understanding of mental disorder cannot be achieved unless we attend to factors that lie outside of the head: neural explanations alone will not fully capture the complex dependencies that exist between an individual’s psychiatric condition and her social, cultural, and material environment. Here, we firstly offer a taxonomy of ways in which the externalist viewpoint can be understood, and unpack its commitments concerning the nature and physical realization of mental disorder. Secondly, we apply a (...) strongly externalist approach to the case of Autistic Spectrum Disorder, and argue that this condition can be illuminated by appeal to the hypothesis of extended cognition. We conclude by briefly considering the significance this strongly externalist approach may have for psychiatric practice and pedagogy. (shrink)

In this paper, we develop an analysis of the structure and content of loneliness. We argue that this is an emotion of absence-an affective state in which certain social goods are regarded as out of reach for the subject of experience. By surveying the range of social goods that appear to be missing from the lonely person's perspective, we see what it is that can make this emotional condition so subjectively awful for those who undergo it, including the profound sense (...) of being unable to realise oneself, in collaboration with others.

This is a book about Hobbes's philosophy as a whole, viewed through the lens of his philosophy of science. Political philosophy is claimed to have a certain autonomy within Hobbes's scheme of philosophy and science as a whole, and in particular, a kind of autonomy in relation to natural sciences. Hobbes's moral and political philosophies guide action --of both individual subjects and sovereigns. They have a role in a special kind of rhetorical product called counsel. In natural science Hobbes probably (...) exaggerates the explanatory powers of mechanics --the theory of matter in motion-- including by an attempted assimilation of geometry to the sciences of motion.

"The well-known moral and political doctrines of Leviathan have tended to overshadow Hobbes's speculations in other fields. In this book doctrines familiar from the treatises on 'Policy', as well as less familiar empirical and metaphysical theories, are given balanced consideration against the background of his philosophy of science."--Bookjacket.

Many individuals have miserable work lives, in which they must toil away at mind-numbing yet exhausting tasks for hours on end, being ordered about by their superiors, perhaps with few guarantees that this source of income will persist for very long. However, this is only half of the story: what is centrally important is that many of those who endure these conditions are denied a fair wage in return for the burdens that they bear. In this article, I reflect on (...) the significance of this fact in order to argue for the evaporation thesis. This thesis holds that individuals’ claims to particular employment-related protections from their government disappear as their earnings increase. In the course of defending this position, I explore the moral difference an employee's wage offer makes to the work conditions that we can expect her to accept, including why there are limits to the role that cash can play here.

Abstract: I examine virtue theory, especially as expressed by Rosalind Hursthouse. In its canonical form, the theory claims that living a life of virtue constitutes flourishing, although it also has a possible fall-back claim that a life of virtue is a means to the end of flourishing. I argue that in both interpretations, virtue theory is mistaken. It cannot give any convincing account of how the concepts of wanting, flourishing, and the virtues are connected, nor can it deal adequately with (...) the counter-examples of flourishing by the wicked, and torment for the virtuous. However, I allow that stripped of all its pretensions to universality, there are grounds for some people in some restricted sets circumstances, to follow the path of virtue solely because they will thereby flourish.

This chapter is divided into three parts. In the first, I ask whether there is a human right to be spared extreme poverty. The answer is ‘Not necessarily’ if a human right is a legal right, and I argue that ‘human right’ either means a right in international law and associated policy, or else the term has an unacceptably wide sense. In the second section I consider microcredit as a poverty-alleviating mechanism, distinguishing between extreme and relative poverty in developing countries. (...) I argue that credit may not be a good way of alleviating extreme poverty, and that methods of collecting debt used by microcredit providers may have moral drawbacks. In the third section I consider the fit between the class of agents currently involved in offering financial services to the poor, and the class of agents recognized as duty-bearers by human rights law and policy. Unless states become highly involved in microcredit, it is not clear that microfinance providers are or can be human rights duty bearers. (shrink)

In a new and fully considered preface, Regan responds to his critics and defends the book's revolutionary position.

Abstract I argue that the traditional problem of evil mislocates the problem which confronts the theist. The real problem arises not from the evil in the world, but from the non-perfection of the world. Given that a perfect God could create only a perfect world, and given that the world is not in fact perfect, I construct an argument for atheism. I show that the argument is not open to the objections which theists standardly bring against the traditional objection from (...) evil. (shrink)

In this paper, I draw a distinction between two types of deepfake, and unpack the deceptive strategies that are made possible by the second. The first category, which has been the focus of existing literature on the topic, consists of those deepfakes that act as a fabricated record of events, talk, and action, where any utterances included in the footage are not addressed to the audience of the deepfake. For instance, a fake video of two politicians conversing with one another. (...) The second category consists of those deepfakes that direct an illocutionary speech act - such as a request, injunction, invitation, or promise - to an addressee who is located outside of the recording. For instance, fake footage of a company director instructing their employee to make a payment, or of a military official urging the populace to flee for safety. Whereas the former category may deceive an audience by giving rise to false beliefs, the latter can more directly manipulate an agent's actions: the speech act's addressee may be moved to accept an invitation or a summons, follow a command, or heed a warning, and in doing so further a deceiver's unethical ends.

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

This paper responds to the reviews by Edwards, Holm, Koch, Thomas and Vehmas of Disability Rights and Wrongs . After summarising the recent history of disability studies as a discipline, it explores: the political nature of disability research, questions of ontology and definition, and the uses and abuses of the expressivist argument. Disability is an emerging field of enquiry and constructive debate is to be welcomed.

Skeletal muscle formation is studied in vitro with myogenic cell lines and primary muscle cell cultures, and in vivo with embryos of several species. We review several of the notable advances obtained from studies of cultured cells, including the recognition of myoblast diversity, isolation of the MyoD family of muscle regulatory factors, and identification of promoter elements required for muscle‐specific gene expression. These studies have led to the ideas that myoblast diversity underlies the formation of the multiple types of fast (...) and slow muscle fibers, and that myogenesis is controlled by a combination of ubiquitous and muscle‐specific transcriptional regulators that may be different for each gene. We further review some unexpected results that have been obtained when ideas from work in culture have been tested in developing animals. The studies in vivo point to additional molecular and cellular mechanisms that regulate muscle formation in the animal. (shrink)

The Language Dynamic identifies a number of mechanisms that enable the meaning potential of language from the phoneme through grammar and discourse and onto ideological systems. This book, which underpins functional theories of language with concepts from biological and cultural evolution, social semiotics and systems theory, is relevant to all who are interested in how and why we can mean and what it means for us as humans to be semiotic agents.

A superb example of the bookmaker's and translator's art, this new edition of Plato's "Symposium" exhibits aesthetic, literary, and intellectual excellences rarely found together in a single volume.Tom Griffith's translation of this foundation work of Western culture is unsurpassed for the balance it achieves between readability and fidelity to Plato's Greek. For felicity of phrasing, freshness, care to match the sense of the Greek rather than its wording, and for its idiomatic rendering of the spoken word, it has no peer.Originally (...) published in a limited edition with facing Greek and color wood engravings, Griffith's translation is here presented in reduced format that retains the aesthetic quality of the original version at an affordable price.

When we understand that something is a pot, is it because of one property that all pots share? This seems unlikely, but without this common essence, it is difficult to see how we could teach someone to use the word "pot" or to see something as _a_ pot. The Buddhist apoha theory tries to resolve this dilemma, first, by rejecting properties such as "potness" and, then, by claiming that the element uniting all pots is their very difference from all non-pots. (...) In other words, when we seek out a pot, we select an object that is not a non-pot, and we repeat this practice with all other items and expressions. Writing from the vantage points of history, philosophy, and cognitive science, the contributors to this volume clarify the nominalist apoha theory and explore the relationship between apoha and the scientific study of human cognition. They engage throughout in a lively debate over the theory's legitimacy. Classical Indian philosophers challenged the apoha theory's legitimacy, believing instead in the existence of enduring essences. Seeking to settle this controversy, essays explore whether apoha offers new and workable solutions to problems in the scientific study of human cognition. They show that the work of generations of Indian philosophers can add much toward the resolution of persistent conundrums in analytic philosophy and cognitive science. (shrink)

How wrong is it to deceive someone into sex by lying, say, about one's profession? The answer is seriously wrong when the liar's actual profession would be a deal breaker for the victim of the deception: this deception vitiates the victim's sexual consent, and it is seriously wrong to have sex with someone while lacking his or her consent.

These original essays, never published before, suggest the breadth and richness of Johann Gottlieb Fichte's philosophy and are signs of the contemporary effort to explore the relationship between his system of thought and current philosophical debates. Some of the issues discussed included the relationship between "theoretical" and "practical" reason; the philosophy of language; antifoundationalism; the juridical status of women; duties toward natural beings; and the political implications of the Wissenschaftslehre. In addition, the volume includes an introduciton that surveys the history (...) of Fichte interpretation in the English-speaking world and assesses the current state of Fichte studies. (shrink)

Arguments for the existence of God have taken many different forms over the centuries: in The Non-Existence of God, Nicholas Everitt considers all of the arguments and examines the role that reason and knowledge play in the debate over God's existence. He draws on recent scientific disputes over neo-Darwinism, the implication of 'big bang' cosmology, and the temporal and spatial size of the universe; and discusses some of the most recent (...) work on the subject, leading to a controversial conclusion.

Alain Badiou offers a distinctive interpretation of time, anchored in his unique metaphysics and philosophy of the event. For Badiou, time is interventional, demarcating a disjunction between two incommensurable sequences of rupture in human history. The concept of disjunction occupies a pivotal role in Badiou’s philosophy of both love and time. This paper provides a comprehensive examination of the temporality of love within the context of Badiou's philosophy. We argue that, when viewed through Badiou’s philosophical lens, love provides an invaluable (...) vantage point for understanding the very creation and transformation of time. As this chapter progresses, a concise exposition of Badiou's metaphysics and his theory of truth procedure is furnished, emphasizing facets that resonate with his philosophy of love. Time is explored from three vantage points: time between worlds, time within a world, and time as difference-as-such. These distinct conceptions of time, when examined in light of love, provide a fertile ground for further developing his concept of time. (shrink)
