This paper explores how the Leviathan that projects power through nuclear arms exercises a unique nuclearized sovereignty. In the case of nuclear superpowers, this sovereignty extends to wielding the power to destroy human civilization as we know it across the globe. Nuclearized sovereignty depends on a hybrid form of power encompassing human decision-makers in a hierarchical chain of command, and all of the technical and computerized functions necessary to maintain command and control at every moment of the sovereign's existence: this (...) sovereign power cannot sleep. This article analyzes how the form of rationality that informs this hybrid exercise of power historically developed to be computable. By definition, computable rationality must be able to function without any intelligible grasp of the context or the comprehensive significance of decision-making outcomes. Thus, maintaining nuclearized sovereignty necessarily must be able to execute momentous life and death decisions without the type of sentience we usually associate with ethical individual and collective decisions.

In lieu of an abstract, here is a brief excerpt of the content:Daoism, Practice, and Politics:From Nourishing Life to Ecological PraxisEric S. Nelson (bio)I. Daoism's Multiple ModelsManhua Li, Yumi Suzuki, and Lisa Indraccola have offered evocative insights, questions, and alternatives in their contributions concerning the arguments of Daoism and Environmental Philosophy: Nourishing Life (Nelson 2021). The present brief response and sketch of the book will not address every point in their essays, but I will strive to reply, directly and indirectly, (...) to their primary concerns.First, it should be noted that I take a pluralistic conception of 'Daoisms' as my point of departure. This is necessary since Daoist studies have been hampered by overly ahistorical and one-sided definitions that prioritize one philosophical or religious moment (such as skepticism or mysticism) in historically complex and varied transmissions that encompass a multiplicity of texts and perspectives. Due to the fact of the plurality of incompatible kinds of Daoism in Chinese antiquity and in subsequent history, my text considers a range of early Daoist and Daoist-related perspectives in the context of their potential consequences for environmental philosophy, ethics, and politics. Consequently, my approach is primarily philosophical without limiting any text to being exclusively philosophical, religious, or rigidly committed to one perspective, which would be untrue to the sources themselves.Second, examining distinctive tendencies (modifying Graham 1989 and Liu 1994) in the Daodejing 道德經, the Zhuangzi 莊子, and related texts enables us to articulate distinctive and conflicting ecological, ethical, and political paradigms. In place of constructing a mythologizing ideological construction of 'Chinese culture' and Daoism as intrinsically 'Green', a familiar essentializing tendency that has provoked skepticism regarding the very possibility of Daoist environmental philosophy, my book provides a different 'critical Daoist' strategy. This alternative entails that Daoist exemplars can be deployed as therapeutic models in the present, while at [End Page 792] the same time confronting their ideological codifications and uses. Early Daoist sources have roamed on long intercultural journeys. The Daodejing and the Zhuangzi have provided elements for European thinking about civilization, technology, and nature from Martin Buber and Martin Heidegger (Nelson 2017) to Peter Sloterdijk's 'Euro-Taoism' (Sloterdijk 1989) to contemporary progressive Green movements (Joshi 2022) and even ecofascism (Lubarda 2020). Similarly, in the current Chinese context, Green Daoism has both critical and authoritarian ideological functions in visions of 'ecological civilization' (shengtai wenming 生態文明) (Schönfeld and Chen 2019) and fears of a 'green leviathan'. Accordingly, it is not accidental that my anarchistic and participatory democratic interpretation of one key thread, which I call 'ziranist' and clarify below, in early Daoist and Wei-Jin mysterious-learning (xuanxue 玄學) discourses, has led to the most intense discussions and controversies about this book. These include the contributions by Li, Suzuki, and Indraccola that propose questions and alternative possibilities concerning agency and responsiveness, authority and self-determination, freedom and fate, and adaptation and intervention, as well as purposive techniques and anti-purposive uselessness.Third, this hermeneutical strategy points toward the tertiary aspect of our preliminary definition of Daoism. It does not primarily name a philosophical theory or a religious worldview. It concerns shifting, overlapping, and diverging ensembles of discourse and practice. This is not the vague ahistorical idea of 'a way of life' but rather refers to how philosophy is enacted through a specific configuration of—to adopt early Greek expressions—logos as dis-course (e.g., argumentation, hermeneutics, logic, rhetoric), ethos (e.g., comportment, orientation, a way of dwelling), and praxis (practices of the self, with others, and with things and nature). Thus, the Laozi 老子 and Zhuangzi collections can be analyzed textually and conceptually as having multiple threads (drawing on a variety of authors and sources) that form constellations in the received texts with better and worse historical, practical, and conceptual readings. My interpretive strategy in this discussion, which does not exclude other approaches, is that these texts express forms of practical instead of merely speculative philosophy. They are suggestive of an ethos of relational freedom, irreducible to rules and techniques, which dismantles hypostatized experiential and linguistic fixations, including moralistic fixations, in order to freely encounter the myriad things and enact and practice the dao in one's own singular way.'Critical Daoism', therefore, serves as a pluralistic, diagnostic, and practical designation...

In lieu of an abstract, here is a brief excerpt of the content:Consciousness and Machines:A Commentary Drawing on Japanese PhilosophyS. D. Noam Cook (bio)Viewed from within the great unity of consciousness, thinking is a wave on the surface of a great intuition.Kitarō NishidaIntroductionRecent developments in AI have made the long-standing debate about what computers can and can't do a major public concern. What we understand the properties of such machines to be, and consequently how we design [End Page 305] and (...) deploy them, will increasingly shape how we live and how we understand ourselves. Thus, there is an urgent need for better understanding of these issues.Susan Schneider, in her book Artificial You: AI and the Future of Your Mind, offers an exceptionally careful and insightful examination of key issues entailed in how we understand AI and ourselves. One of her central concerns is how we might test for machine consciousness. Given the variations in design and function among current and projected AIs, Schneider sees no likely one-size-fits-all test. So, she offers a battery of different tests that she believes together will make such testing more reliable. This seems a wise approach, and reflects the conceptual and pragmatic care Schneider takes throughout the book.Similarly, it seems to me that the question of machine consciousness should also include various understandings of consciousness itself. What consciousness is taken to be has varied widely both historically and culturally. No commonly accepted single understanding has emerged, and may never emerge. Just as having a battery of tests might help us better assess possible machine consciousness, having different understandings of consciousness might give us a better understanding of what we are testing for. The two should work in tandem, each gauging and shaping the other.Like the development of computers themselves, the predominant thinking about AI has been shaped, in part, by key presuppositions of a scientific worldview, with its origins in Western thought and culture. Among these presuppositions are materialism, reductionism, and a primary focus on objective behavior. These are reflected in the common concern with observable behavior of physical aspects of the brain in efforts to understand human consciousness, which in turn has become a familiar model for work on machine consciousness. All this is important and valuable work. But, in the spirit of Schneider's cautions, it should not be taken as one-size-fits-all. Accordingly, I offer one view of consciousness from a different perspective.In what follows, I sketch out an understanding of consciousness that draws on Japanese philosophy, particularly that of the highly influential early twentieth-century Japanese philosopher Kitarō Nishida (1870–1945). I then explore how the tests for machine consciousness that Schneider proposes might be viewed from that perspective.Consciousness: A Perspective from Japanese PhilosophyConsciousness was a central concern for Nishida, whose philosophy is deeply informed by Japanese culture and by Zen theory and practice. As one might expect from such a philosopher, Nishida's exploration of consciousness is not concerned with properties of the brain, but with what we might discern through disciplined reflection on the experience of our own consciousness. Ultimately, he views consciousness as an organic whole [End Page 306] of systemically organized interrelationships of activities and sensations within our subjective experience. This may be understood by first considering 'nothingness'.For Nishida, nothingness does not suggest an ultimate and absolute vacuity, as is often understandably assumed. In Nishida's sense, it is a singular "place" that mirrors the multifaceted world of our common experience. In understanding this, I am told by native Japanese speakers that the English word 'nothingness' has an advantage over the Japanese equivalent, 'mu', in that 'nothingness' can usefully be broken down as 'nothing-ness'. This suggests that nothingness is a state of consciousness where what we commonly experience as distinct (self, other, world, blue, ache, joy, etc.) is indistinct, a state of unified experience. This is consciousness without our finding or discriminating in it the myriad "things" of common experience, but rather a "pure experience" of a singular whole. Nishida introduces his concept of "pure experience" as follows:To experience means to know facts just as they are, to know in accordance with facts by completely relinquishing one... (shrink)

ArgumentIn the winter of 1849–1850 in Königsberg, German physiologist Hermann von Helmholtz (1821–1894) conducted pioneering measurements concerning the propagation speed of stimulations in the living nerve. While recent historians of science have paid considerable attention to Helmholtz's uses of the graphic method, in particular his construction of an instrument called “myographion,” this paper draws attention to theinscription surfacesthat he used in effective ways for capturing and transmitting his findings. Against the background of recent archival findings, I show that Helmholtz used (...) isinglass copies of his graphical recordings in order to communicate the basic principle of previous measurements to the academic public. As the correspondence with his Berlin-based friend and colleague Emil du Bois-Reymond (1818–1896) and the subsequent development of the myographion make clear, these curves were not meant as measurements but functioned as demonstrations. In other words, Helmholtz's curves did provide “images of precision” (Olesko and Holmes 1993) – but they were not precise images. (shrink)

Thomas Hobbes took a new look at the ways in which society should function, and he ended up formulating the concept of political science. His crowning achievement, Leviathan, remains among the greatest works in the history of ideas. Written during a moment in English history when the political and social structures as well as methods of science were in flux and open to interpretation, Leviathan played an essential role in the development of the modern world. This edition of Hobbes' (...) landmark work is based on the original text. It incorporates the author's own corrections and retains the period spelling and punctuation, offering both flavorful authenticity and the utmost clarity of expression. (shrink)

This article explores Herodian's History of the Roman Empire alongside Chariton's novel Callirhoe with an eye to how the minds of collective entities are represented and function in the two narratives. It argues that Chariton, unlike Herodian, elaborates on the diversity of emotions that characterizes a specific collective experience and has groups use direct speech throughout. These choices add vividness to the narrative and intensify the fictional sensationalism and dramatic character of the novel. It also shows that, whereas collectives (...) in Chariton's narrative are primarily designed to highlight a specific characteristic of a hero, dramatize an event and enhance suspense, in Herodian's historiography they are an integral part of the plot and central to his historical analysis of contemporary political and social world. This article offers a new analytical tool geared towards the development of a poetics of the collective in ancient narrative as well as a poetics of fictional and factual narration in antiquity, and advances our understanding of the complex relationship between ancient historiography and novelistic writing.

The fundamental ideas concerning computation and recursion naturally find their place at the interface between logic and theoretical computer science. The contributions in this book, by leaders in the field, provide a picture of current ideas and methods in the ongoing investigations into the pure mathematical foundations of computability theory. The topics range over computable functions, enumerable sets, degree structures, complexity, subrecursiveness, domains and inductive inference. A number of the articles contain introductory and background material which it is hoped will (...) make this volume an invaluable resource for specialists and non-specialists alike. (shrink)

This article presents the results of an experiment that completely measures the utility function and probability weighting function for different positive and negative monetary outcomes, using a representative sample of N = 1,935 from the general public. The results confirm earlier findings in the lab, suggesting that utility is less pronounced than what is found in classical measurements where expected utility is assumed. Utility for losses is found to be convex, consistent with diminishing sensitivity, and the obtained loss-aversion (...) coefficient of 1.6 is moderate but in agreement with contemporary evidence. The estimated probability weighting functions have an inverse-S shape and they imply pessimism in both domains. These results show that probability weighting is also an important phenomenon in the general population. Women and lower educated individuals are found to be more risk averse, in agreement with common findings. In contrast to previous studies that ascribed gender differences in risk attitudes solely to differences in the degree utility curvature, however, our results show that this finding is primarily driven by loss aversion and, for women, also by a more pessimistic psychological response toward the probability of obtaining the best possible outcome.

S. A. Lloyd proposes a radically new interpretation of Hobbes's Leviathan that shows transcendent interests - interests that override the fear of death - to be crucial to both Hobbes's analysis of social disorder and his proposed remedy to it. Most previous commentators in the analytic philosophical tradition have argued that Hobbes thought that credible threats of physical force could be sufficient to deter people from political insurrection. Professor Lloyd convincingly shows that because Hobbes took the transcendence of religious and (...) moral interests seriously, he never believed that mere physical force could ensure social order. Lloyd's interpretation demonstrates the ineliminability of that half of Leviathan devoted to religion, and attributes to Hobbes a much more plausible conception of human nature than the narrow psychological egoism traditionally attributed to Hobbes.

What motivated an absolutist Erastian who rejected religious freedom, defended uniform public worship, and deemed the public expression of disagreement a catalyst for war to endorse a movement known to history as the champion of toleration, no coercion in religion, and separation of church and state? At least three factors motivated Hobbes’s 1651 endorsement of Independency: the Erastianism of Cromwellian Independency, the influence of the politique tradition, and, paradoxically, the contribution of early-modern practices of toleration to maintaining the public sphere’s (...) religious uniformity. The third factor illustrates how a key function of the emerging private sphere in the early-modern period was to protect uniformity, rather than diversity; it also shows that what was novel was not so much the public/private distinction itself, but the separation of two previously conflated dimensions of publicity – visibility and representativeness – that enabled early-modern Europeans to envisage modes of worship out in the open, yet still private.

We propose a formal framework for interpretable machine learning. Combining elements from statistical learning, causal interventionism, and decision theory, we design an idealised explanation game in which players collaborate to find the best explanation for a given algorithmic prediction. Through an iterative procedure of questions and answers, the players establish a three-dimensional Pareto frontier that describes the optimal trade-offs between explanatory accuracy, simplicity, and relevance. Multiple rounds are played at different levels of abstraction, allowing the players to explore overlapping causal (...) patterns of variable granularity and scope. We characterise the conditions under which such a game is almost surely guaranteed to converge on a optimal explanation surface in polynomial time, and highlight obstacles that will tend to prevent the players from advancing beyond certain explanatory thresholds. The game serves a descriptive and a normative function, establishing a conceptual space in which to analyse and compare existing proposals, as well as design new and improved solutions. (shrink)

This book presents a thorough overview of a model of human functioning based on the idea that behavior is goal-directed and regulated by feedback control processes. It describes feedback processes and their application to behavior, considers goals and the idea that goals are organized hierarchically, examines affect as deriving from a different kind of feedback process, and analyzes how success expectancies influence whether people keep trying to attain goals or disengage. Later sections consider a series of emerging themes, including dynamic (...) systems as a model for shifting among goals, catastrophe theory as a model for persistence, and the question of whether behavior is controlled or instead 'emerges'. Three chapters consider the implications of these various ideas for understanding maladaptive behavior, and the closing chapter asks whether goals are a necessity of life. Throughout, theory is presented in the context of diverse issues that link the theory to other literatures. (shrink)

Using recent results in topos theory, two systems of higher-order logic are shown to be complete with respect to sheaf models over topological spaces-so-called "topological semantics". The first is classical higher-order logic, with relational quantification of finitely high type; the second system is a predicative fragment thereof with quantification over functions between types, but not over arbitrary relations. The second theorem applies to intuitionistic as well as classical logic.

The history of corporations in the United States (U.S.) is much older than the country, as it must be understood in the context of the history of peoples of Europe who eventually dominated the North American continent in the seventeenth and eighteenth centuries. These European settlers came, in part, to achieve economic prosperity for themselves and, in many cases, for early forerunners of the modern corporation. These business organizations had predecessors in Europe millennia earlier as ancient Romans had developed a (...) functional and successful form of corporation for the purpose of conducting commerce in the Roman Empire. In the decades that followed the founding of the U.S. in 1776, corporations evolved from rare, small, closely controlled business organizations with a multitude of restrictions to very large, very powerful modern institutions that enjoy many of the legal rights of humans. With this evolution came ethical issues, as (1) the ethical distance was altered between corporate decision-makers and those affected by those decisions, and (2) many of the legal rights of individual humans were extended, through litigation, to corporations. This article explains the historical development of the U.S. corporation and identifies 20 Critical Events in the Ethics of Corporation History (CEECH). An understanding of these historical events may facilitate comprehension of many of the current ethical issues associated with a legal organizational form that profoundly affects business and society.

This review essay of Economics Rules situates Dani Rodrik’s contribution with respect to the 2007–2008 global economic crisis. This financial meltdown, which the eurozone did not fully recover from before the Covid-19 pandemic, led to soul- searching among economists as well as a call for heterodox economic approaches. Yet, over the past decade, instead the economics profession has maintained its orthodoxy. Rodrik’s Economics Rules offers a critique of the economics profession that is castigating but mild. It calls for economists to (...) use more and diverse models without becoming wedded to any single model or an overarching vision. Yet Rodrik ratifies many of the benchmark models standard to orthodox economics and provides little ground for a fundamental rethinking of the discipline. This essay analyses the conservatism underlying Rodrik’s approach, which upholds general equilibrium theory and rational expectations underlying the efficient market hypothesis. It argues that the economics discipline’s scope-creep to maintain its applicability to all human decision-making, and its acceptance of all-inclusive utility functions, crowds out moral sentiments and civic virtue. Thus. it argues that rather than urging economists simply to be more cautious in their application of models to address particular social concerns, instead economists must recognise their discipline’s inherent limitations.

De Coubertin developed the sport philosophy of Olympism and the Olympic Games as a response to social and political crisis to promote peace, fair play, and the development of Christian masculinity. The purpose of this paper is to examine how crisis discourse functions as an important shaper of contemporary understandings of Olympism and how conflicting discourses have mobilized crisis discourse to produce competing 'truths' in which to rationalize and understand the Olympic Games. In drawing from Foucault's work and de Certeau's (...) text, Heterologies: Discourse on the other, I argue that 'crisis' as the rationalization for Olympism and the Olympic Games has proven an unsuccessful venture for de Coubertin; as the Olympic Games have produced conservative outcomes based on a neoliberal agenda focused on elitism, professionalism, nationalism, and commercialism. This historical case raises important questions about the role of Olympism and its power to act as a catalyst for change. (shrink)

This fourth edition of one of the classic logic textbooks has been thoroughly revised by John Burgess. The aim is to increase the pedagogical value of the book for the core market of students of philosophy and for students of mathematics and computer science as well. This book has become a classic because of its accessibility to students without a mathematical background, and because it covers not simply the staple topics of an intermediate logic course such as Godel's Incompleteness Theorems, (...) but also a large number of optional topics from Turing's theory of computability to Ramsey's theorem. John Burgess has now enhanced the book by adding a selection of problems at the end of each chapter, and by reorganising and rewriting chapters to make them more independent of each other and thus to increase the range of options available to instructors as to what to cover and what to defer.

Throughout its long history metaphysics has been variously conceived. At its most sublime, it has been taken to be the study of the super‐sensible, in particular of the existence of a god, the nature of the soul, and the possibility of an afterlife. When the young Ludwig Wittgenstein entered the lists, it was entirely reasonable to conceive of metaphysics in this manner. Its subject matter was held to be the language‐independent and thought‐independent de re necessities of the world. The Tractatus (...) is dominated by three problems: first, the nature of logic and logical necessity; secondly, the essence of the proposition and hence the characterization of the general propositional form; and thirdly, the intentionality of the proposition. Logical propositions are combinations of elementary propositions by means of truth‐functional logical connectives. The metaphysics adumbrated in the Tractatus, Wittgenstein thought, was required for the possibility of representation and for the possibility of logic. (shrink)

The purported failures of ergodic theory (seen in its often proved ineptitude to ground a mechanical explanation of thermodynamics) are shown to arise from misconception of the functions served by scientific explanation. In fact, the predictive failures of ergodic theory are precisely its points of greatest physical utility, where genuinely new knowledge about actual physical systems can be obtained, once the links between explanation and reconstructive estimation are recognized.

This paper explores how the diagnosis of mental disorder may affect the diagnosed subject’s self-concept by supplying an account that emphasizes the influence of autobiographical and social narratives on self-understanding. It focuses primarily on the diagnoses made according to the criteria provided by the Diagnostic Statistical Manual of Mental Disorders (DSM), and suggests that the DSM diagnosis may function as a source of narrative that affects the subject’s self-concept. Engaging in this analysis by appealing to autobiographies and memoirs written (...) by people diagnosed with mental disorder, the paper concludes that a DSM diagnosis is a double-edged sword for self- concept. On the one hand, it sets the subject’s experience in an established classificatory system which can facilitate self-understanding by providing insight into subject’s condition and guiding her personal growth, as well as treatment and recovery. In this sense, the DSM diagnosis may have positive repercussions on self-development. On the other hand, however, given the DSM’s symptom-based approach and its adoption of the Biomedical Disease model, a diagnosis may force the subject to make sense of her condition divorced from other elements in her life that may be affecting her mental- health. It may lead her frame her experience only as an irreversible imbalance. This form of self-understanding may set limits on the subject’s hopes of recovery and may create impediments to her flourishing. (shrink)

Focusing on nuclear command and control, avoiding (...) autonomy and machine learning is recommended as one means to reduce the existential risk of unintended nuclear conflict. (shrink)

This paper proposes a Cournot game organized by three competing firms adopting bounded rationality. According to the marginal profit in the past time step, each firm tries to update its production using local knowledge. In this game, a firm’s preference is represented by a utility function that is derived from a constant elasticity of substitution production function. The game is modeled by a 3-dimensional discrete dynamical system. The equilibria of the system are numerically studied to detect their complex (...) characteristics due to difficulty to get an explicit form for those equilibria. For the proposed utility function, some cases with different value parameters are considered. Numerical simulations are used to provide an experimental evidence for the complex behavior of the evolution of the system. The obtained results show that the system loses its stability due to different types of bifurcations. (shrink)

The approach used by physics is based on the identification and study of ideal objects, which is also the basis of biophysics, in combination with von Neumann heuristic modeling and functional fractionation according to R.Rosen is discussed as a tool for studying the properties of consciousness. The object of the study is a kind of line of analog systems: the human brain, the vertebrate brain, the invertebrate brain and artificial neural networks capable of reflection, which is a key property characteristic (...) of consciousness. Reflection in the broad sense of the word, understood as an internal representation of the external world, is characteristic of a wide range of animals, and some of them (bumblebees, fish) even demonstrate reflection in the narrow sense of the word, understood as an inner self-representation. This complex behavior is realized by miniature brains of ~1 million neurons. The use of simple recurrent neural networks (RNNs) to obtain answers to general questions is illustrated. For example, it has been shown a small RNS is able to pass delayed matching to sample (DMTS) test, forming an individual dynamic representation of the received stimulus, allowing decoding by a special external neural detector.. It has been demonstrated in the reflexive game “even-odd”, the RNS has a huge advantage over a multi-layered neural network, with the same and a larger number of neurons – reflection defeats regression. It was found that the asymmetry of outcomes in the odd-even game, which was explained by various causes, including psychological ones – “it’s easier to catch up than to run away”, is reproduced in the game of two RNNs. Obviously, there are no psychological causes here and the advantage of the player playing for “even” is explained by the more complex strategy of the “odd” player – he needs to predict the opponent’s move and choose the opposite one.

Michael Lynch’s Truth as One and Many is a contribution to the large body of philosophical literature on the nature of truth. Within that genre, advocates of truth-as-correspondence, advocates of truth-as-coherence, and the like, all hold that truth has a single underlying metaphysical nature, but they sharply disagree as to what this nature is. Lynch argues that many of these views make good sense of truth attributions for a limited stretch of discourse, but he adds that each of the contenders (...) also faces a ‘scope problem’, in that none of them makes sense of all legitimate truth attributions. Some deflationists make similar observations – usually less concessive – and conclude that truth simply has no substantial, underlying nature. There is nothing for the philosopher to articulate and defend. Lynch agrees with deflationists that the realm of discourse is too diverse for any single ‘first-level’ property, such as correspondence or coherence, to fully characterize it, but against deflationism, he holds that truth does have a nature. He presents a functionalist theory. The definition is this: x is true if, and only if, x has a property that plays the truth-role. According to Lynch, the truth-role is given in terms of what he calls the ‘core truisms’ of the folk concept of truth. These are platitudes that hold of the everyday notion, and are such that anyone who denies all of them can be accused of changing the subject – of not talking about truth. A given property T plays the truth-role for a batch of propositions, just in case, for any proposition P in the batch: P is T if, and only if, where P is believed, things are as they are believed to be; other things being equal, it is a worthy goal ….

Plato's dialogues frequently criticize traditional Greek myth, yet Plato also integrates myth with his writing. Daniel S. Werner confronts this paradox through an in-depth analysis of the Phaedrus, Plato's most mythical dialogue. Werner argues that the myths of the Phaedrus serve several complex functions: they bring nonphilosophers into the philosophical life; they offer a starting point for philosophical inquiry; they unify the dialogue as a literary and dramatic whole; they draw attention to the limits of language and the limits of (...) knowledge; and they allow Plato to co-opt cultural authority as a way of defining and legitimating the practice of philosophy. Platonic myth, as a species of traditional tale, is thus both distinct from philosophical dialectic and similar to it. Ultimately, the most powerful effect of Platonic myth is the way in which it leads readers to participate in Plato's dialogues and to engage in a process of self-examination. (shrink)

The Humean conception of the self consists in the belief-desire model of motivation and the utility-maximizing model of rationality. This conception has dominated Western thought in philosophy and the social sciences ever since Hobbes’ initial formulation in Leviathan and Hume’s elaboration in the Treatise of Human Nature. Bentham, Freud, Ramsey, Skinner, Allais, von Neumann and Morgenstern and others have added further refinements that have brought it to a high degree of formal sophistication. Late twentieth century moral philosophers such as Rawls, (...) Brandt, Frankfurt, Nagel and Williams have taken it for granted, and have made use of it to supply metaethical foundations for a wide variety of normative moral theories. But the Humean conception of the self also leads to seemingly insoluble problems about moral motivation, rational final ends, and moral justification. Can it be made to work? (shrink)

Readers of Hobbes have often seen his Leviathan as a deeply paradoxical work. On one hand, recognizing that no sovereign could ever wield enough coercive power to maintain social order, the text recommends that the state enhance its power ideologically, by tightly controlling the apparatuses of public discourse and socialization. The state must cultivate an image of itself as a mortal god of nearly unlimited power, to overpower its subjects and instil enough fear to win obedience. On the other hand, (...) by drawing explicit attention to the ideological and partly illusory bases of the state’s power, Leviathan, itself construed as a political intervention designed to appeal to a broad English readership, appears to undermine the very program it recommends. Indeed, many have argued that Leviathan’s substantive political-philosophical doctrine is flatly at odds with the authority that Hobbes claimed for himself in order to advance that doctrine. The paradox, I argue, is only an apparent one. Precisely because Hobbes believed that in practice no one could ever become the mortal god that sovereignty requires, i.e., that the seat of sovereignty could never actually be securely occupied and fully represented by a mere mortal, he sought constantly to remind his readers of the precariousness of earthly sovereignty by pointing to its illusory basis. Far from seeking to undermine the sovereign, however, this reminder was designed to enhance readers’ fears, especially the fear that, despite the security they may enjoy today, the slightest misstep may lead them straight into the horrors of the state of nature. Hobbes’s purpose was, in other words, to enhance the sovereign’s power, not by enhancing our fear of him, but of his absence. Ironically, this is also in part why Hobbes insisted on the individual’s inalienable right of self-defence, an insistence that has puzzled many of his readers, given Hobbes’s obvious wish to defend absolute, unlimited sovereignty. Its political function is not to provide a covert justification for resistance theories. Rather, by reminding his readers of their right but doing so while addressing them as isolated atoms whose resistance would be hopeless, Hobbes sought to remind each one of the ultimate impossibility of securely filling the seat of sovereignty, without encouraging anyone actually to resist the most promising pretender. Like God-talk, Hobbes’s representations of sovereign power do not ultimately comprise descriptive propositions at all: they are expressions of praise and honour designed to help create the very thing they purport to describe. Hobbes was keenly aware that indivisible state sovereignty is an ideological construct whose terms are never ever fully realized in practice. (shrink)
