It's often said that according to deflationary theories of truth, truth is not a ‘substantial’ property. While this is a fine slogan, it is far from transparent what deflationists mean (or ought to mean) in saying that truth is ‘insubstantial’. Focusing so intently upon the concept of truth and the word ‘true’, I argue, deflationists and their critics have been insufficiently attentive to a host of metaphysical complexities that arise for deflationists in connection with the property of truth. My aim (...) is to correct several misunderstandings as to what deflationists are after here—including some harboured by deflationists themselves—and to offer an account of the commitments about truth's nature that they ought to undertake. In developing this account, I focus particularly upon the issue of what metaphysics of truth a Horwichian minimalist ought to adopt. (shrink)

Lady Mary Shepherd’s critique of Hume’s account of causation, his worries about knowledge of matters of fact, and the contention that it is possible for the course of nature to spontaneously change relies primarily on three premises, two of which – that objects are merely bundles of qualities and that the qualities of an object are individuated by the causal powers contributed by those qualities – anticipate contemporary metaphysical views in ways that she should be getting credit for. The remaining (...) premise – that it is impossible for an object to begin to exist uncaused – seems more old fashioned. I argue that Shepherd can do without her old-fashioned premise and that she provides the materials for arguing that her remaining premises demonstrate a stronger anti-Humeanism than is maintained even by the contemporary representatives of those views, even though she may have to concede more to Humeanism than she would like.

We discuss from a philosophical perspective the way in which the normal concept of time might be said to `emerge' in a quantum theory of gravity. After an introduction, we briefly discuss the notion of emergence, without regard to time. We then introduce the search for a quantum theory of gravity ; and review some general interpretative issues about space, time and matter. We then discuss the emergence of time in simple quantum geometrodynamics, and in the Euclidean approach. Section 6 (...) concludes. (shrink)

I discuss how modern cosmology illustrates under-determination of theoretical hypotheses by data, in ways that are different from most philosophical discussions. I emphasise cosmology's concern with what data could in principle be collected by a single observer ; and I give a broadly sceptical discussion of cosmology's appeal to the cosmological principle as a way of breaking the under-determination.I confine most of the discussion to the history of the observable universe from about one second after the Big Bang, as described (...) by the mainstream cosmological model: in effect, what cosmologists in the early 1970s dubbed the ‘standard model’, as elaborated since then. But in the closing Section 4, I broach some questions about times earlier than one second. (shrink)

I investigate the role of geometric intuition in Frege’s early mathematical works and the significance of his view of the role of intuition in geometry to properly understanding the aims of his logicist project. I critically evaluate the interpretations of Mark Wilson, Jamie Tappenden, and Michael Dummett. The final analysis that I provide clarifies the relationship of Frege’s restricted logicist project to dominant trends in German mathematical research, in particular to Weierstrassian arithmetization and to the Riemannian conceptual/geometrical tradition at Göttingen. (...) Concurring with Tappenden, I hold that Frege’s logicism should not be understood as a continuing a project of reductionist arithmetization. However, Frege does not quite take up the Riemannian banner either. His logicism supports a hierarchical understanding of the structure of mathematical knowledge, according to which arithmetic is applicable to geometry but not vice versa because the former is more general, as revealed by the strictly logical nature of its objects in comparison to the intuitional nature of geometric objects. I suggest, in particular, that Frege intended that foundational work would show the use of geometric intuition in complex analysis, a source of error for Riemann that Weierstrass was proud to have uncovered, to be inessential.

One important strand of Sellars’s attack on classical foundationalism from Empiricism and the Philosophy of Mind is his thesis about the priority of is-talk over looks-talk. This thesis has been criticized extensively in recent years, and classical foundationalism has found several contemporary defenders. I revisit Sellars’s thesis and argue that is-talk is epistemically prior to looks-talk in a way that undermines classical foundationalism. The classical foundationalist claims that epistemic foundations are constituted by the agent’s set of looks-judgments. However, I argue (...) that only a subset of these looks-judgments are even candidates to serve as foundations for the agent’s empirical knowledge, and membership in this subset is determined by the agent’s theory of how the world is. Thus, the epistemic force of the looks-judgments in this subset is dependent on the agent’s theory of how the world is. This means that these looks-judgments aren’t foundational at all, as the agent’s theory of how the world is is epistemically is prior to the epistemic status of these looks-judgments. This is the sense in which judgments about how the world is are epistemically prior to judgments about how things look. This conclusion allows concrete elaboration of another of Sellars’s well-know claims: “I do wish to insist that the metaphor of ‘foundation’ is misleading in that it keeps us from seeing that if there is a logical dimension in which other empirical propositions rest on observation reports, there is another logical dimension in which the latter rest on the former”.

Abstract: This paper assesses the Everettian approach to the measurement problem, especially the version of that approach advocated by Simon Saunders and David Wallace. I emphasise conceptual, indeed metaphysical, aspects rather than technical ones; but I include an introductory exposition of decoherence. In particular, I discuss whether---as these authors maintain---it is acceptable to have no precise definition of 'branch' (in the Everettian kind of sense). (A version of this paper will appear in a CTNS/Vatican Observatory volume on Quantum Theory and (...) Divine Action, ed. Robert Russell et al.). (shrink)

Most studies on climate change response have examined reductions in greenhouse gas (GHG) emissions. Yet these studies do not take into account ecosystem services constraints and biophysical disruptions wrought by climate change that may require broader types of response. By studying a firm in the wine industry and using a research approach not constrained by structured methodologies or biased toward GHG emissions, the findings suggest that both “inside out” and “outside in” actions are taken in response to climate change. While (...) attempts are made by the firm to curtail and reverse climate change through management of carbon emissions, evidence suggests a clear pattern of actions designed to adjust to the adverse consequences of climate change as well. The results both confirm and extend previous findings and suggest that the level and breadth of response to climate change is shaped by situated attention, structural controls, and industry type.

Did Plato intend the laws of the Laws to change? While most scholars agree that there is to be legal change in Magnesia, I contend that this issue has been clouded by confusing three distinct questions: (1) whether there are legal mechanisms for changing the law in Magnesia, (2) what the attitudes of Magnesian citizens towards innovation and legal change are, and (3) whether Plato thinks the law is always the ultimate political authority. Once we separate these issues and look (...) at the relevant texts more closely, we see that the Athenian Visitor is primarily concerned with supplementing the original lawgiver’s laws and that any innovation that occurs should be consistent with this lawcode. This does not settle the question about whether it is always right to act in accordance with the existing laws, though it does provide a valuable framework for understanding a central aspect of Platonic political philosophy. Thus, although Plato’s ideal places knowledge above the law, in practice the laws of Magnesia will be fixed and authoritative for those people living under them. (shrink)

We investigate the entrepreneurial opportunities and ethical dilemmas presented by technological turbulence. More specifically we investigate the line between Baumol’s [J. Polit. Econ. 98 (1990) 893] productive (e.g. innovation), unproductive (e.g. rent seeking) and destructive (e.g. criminal) entrepreneurship through three examples of Internet innovation – spam (destructive), music file sharing (unproductive), and Internet pharmacies (potentially productive). The emergence of accessible Internet technologies, under present norms, has created the potential for all three entrepreneurial activities. Because of the propensity for self-serving biases (...) and for bending the rules, the need for creativity in overcoming obstacles and overall liabilities of newness, entrepreneurs are likely to challenge established industrial morals and laws. Unlike new entrants, incumbents must abide by the currently accepted norms, and thus suffer from “liabilities of oldness”. The challenge for new entrants is to change sociopolitical legitimacy, whereas incumbents need to defend the established norms. We discuss competitive and other issues that result from technological turbulence and innovation. (shrink)

These nine essays address fundamental questions about time in philosophy, physics, linguistics, and psychology. Are there facts about the future? Could we affect the past? In physics, general relativity and quantum theory give contradictory treatments of time. So in the current search for a theory of quantum gravity, which should give way: general relativity or quantum theory? In linguistics and psychology, how does our language represent time, and how do our minds keep track of it?

I discuss how modern cosmology illustrates underdetermination of theoretical hypotheses by data, in ways that are different from most philosophical discussions. I confine the discussion to the history of the observable universe from about one second after the Big Bang, as described by the mainstream cosmological model: in effect, what cosmologists in the early 1970s dubbed the ‘standard model’, as elaborated since then. Or rather, the discussion is confined to a (very!) few aspects of that history. I emphasize that despite (...) the underdetermination, a scientific realist can, and should, endorse this description.

Practical cognitivism is the view that practical reason is our will, not an intellectual capacity whose exercises can influence those of our will. If practical reason is our will, thoughts about how I am to act have an essential tie to action. They are intentions. Thoughts about how others are to act, though, lack such a tie to action. They are beliefs, not intentions. How, then, can these thoughts form a unified class? I reject two answers which deny the differences (...) between such thoughts about myself and those about others, one of which says that all such thoughts are intentions, the other that all are beliefs. I then reject a shared assumption which says that a class of thoughts is unified only if all its elements are all of one type of thought. I instead argue that this class is unified even though some elements are intentions, others beliefs, because such beliefs depend on those intentions in various ways. (shrink)

Hybrid languages are introduced in order to evaluate the strength of “minimal” mereologies with relatively strong frame definability properties.

Complementary and alternative medicine is used by many in hopes of achieving important health-related goals. Survey data indicate that 42 percent of the U.S. population uses CAM, accounting for 629 million “office” visits a year and expenditures of 27 billion dollars. This high prevalence of use calls for a careful evaluation of CAM so as to ensure the well-being of those using its modalities. Such an evaluation would obviously include assessments of the safety and efficacy of particular approaches, the training (...) and integrity of practitioners, and the appropriateness of modalities for different conditions or uses. Given the lack of published data concerning many of these aspects of CAM, the likely unfamiliarity of its practitioners to the approaches available to clinicians practicing modern scientific medcine, and the need to respect the unique preferences of persons seeking assistance with achieving health-related goals, it is also important to assess the potential roles of informed consent for the use of CAM. Examining such roles is the central task of this paper. (shrink)

Little research has considered the potential influence of distant, external pressures on the implementation of firms’ ‘green’ innovations, nor how internal firm resources might moderate this relationship. By combining institutional and resource-based theories and examining 649 firms in Australia, I find that export intensity is positively associated with green innovations. Further, as women in leadership roles increase in firms, the relationship strengthens between export intensity and green innovations. The results also suggest that greater levels of absorptive capacity among firms strengthen (...) the relationship between export intensity and green innovations. Contributions of the findings are discussed along with limitations and future research opportunities. (shrink)

This paper discusses some of the modal involvements of analytical mechanics. I first review the elementary aspects of the Lagrangian, Hamiltonian and Hamilton-Jacobi approaches. I then discuss two modal involvements; both are related to David Lewis' work on modality, especially on counterfactuals. The first is the way Hamilton-Jacobi theory uses ensembles, i.e. sets of possible initial conditions. The structure of this set of ensembles remains to be explored by philosophers. The second is the way the Lagrangian and Hamiltonian approaches' variational (...) principles state the law of motion by mentioning contralegal dynamical evolutions. This threatens to contravene the principle that any actual truth, in particular an actual law, is made true by actual facts. Though this threat can be avoided, at least for simple mechanical systems, it repays scrutiny; not least because it leads to some open questions. (shrink)

This paper expounds the relations between continuous symmetries and conserved quantities, i.e. Noether's ``first theorem'', in both the Lagrangian and Hamiltonian frameworks for classical mechanics. This illustrates one of mechanics' grand themes: exploiting a symmetry so as to reduce the number of variables needed to treat a problem. I emphasise that, for both frameworks, the theorem is underpinned by the idea of cyclic coordinates; and that the Hamiltonian theorem is more powerful. The Lagrangian theorem's main ``ingredient'', apart from cyclic coordinates, (...) is the rectification of vector fields afforded by the local existence and uniqueness of solutions to ordinary differential equations. For the Hamiltonian theorem, the main extra ingredients are the asymmetry of the Poisson bracket, and the fact that a vector field generates canonical transformations iff it is Hamiltonian. (shrink)

No contemporary compatibilist account of free will can be complete unless it engages with the consequence argument. I will argue that Wilfrid Sellars offered an ingenious version of compatibilism that can be used to refute the consequence argument. Unfortunately, owing to the opacity of Sellars’s writings on free will, his solution has been neglected. I will reconstruct his view here, demonstrating how it represents a powerful challenge to the consequence argument and tying it to some recent developments in the compatibilist (...) literature.

Among the many obscure sects of sexual fetishism, few remain as perplexing as that of the “crush freaks,” who are aroused by the sight of an insect exploded beneath a human foot. Moving beyond the glib discussions of those entomologists and sexologists who classify this fetish as a subset of foot worship and/or macrophilia, I propose an analysis of the crush freaks through the writings of French thinker Georges Bataille. Employing Bataille’s notions of sacrificial eroticism and mysticism to approach the (...) religio-sexual dimensions of crush freakism, I argue that these practices are best understood as ambivalent manifestations of technophilia . More specifically, crush freakism, I submit, devolves on a violent literalization of the analogies between insects and machines. (shrink)

The COVID-19 global pandemic has shone a light on several important ethical questions, ranging from fairness in resource allocation to the ethical justification of government mandates. In addition to these institutional issues, there are also several ethical questions that arise at the interpersonal level. This essay focuses on several of these issues. In particular, I argue that, despite the insistence in public health messaging that avoiding infecting others constitutes ‘saving lives’, virus transmission that results in death constitutes an act of (...) killing. Whether this killing is wrongful depends on several factors. I consider one intuitively plausible view—namely, that in many cases, killing via unintentional transmission is not wrongful, because the parties in question have implicitly waived their rights against this harm, often via reciprocal risk imposition. I argue that this view is mistaken, but that its central insight can be better captured by identifying the appropriate standards of blame that we ought to apply during a pandemic. I conclude by showing how these conclusions can be fruitfully applied to certain institutional questions, such as helping to justify restricting government mandates. (shrink)

In Section 2, I survey some of the ways that computers are used in mathematics. These raise questions that seem to have a generally epistemological character, although they do not fall squarely under a traditional philosophical purview. The goal of this article is to try to articulate some of these questions more clearly, and assess the philosophical methods that may be brought to bear. In Section 3, I note that most of the issues can be classified under two headings: some (...) deal with the ability of computers to deliver appropriate “evidence” for mathematical assertions, a notion that is explored in Section 4, while others deal with the ability of computers to deliver appropriate mathematical “understanding,” a notion that is considered in Section 5. Final thoughts are provided in Section 6. (shrink)

Bentham offers a detailed critique of William Blackstone's 'Commentaries on the Laws of England' (1765-9).

When people now talk about a relationship as being “Platonic”, they mean that the relationship is a non-sexual friendship. But what did Plato himself say about different kinds of relationship, and how did his name come to be associated with non-sexual relationships? While Plato’s Symposium has been the center of attention for his views on love, I argue that the Phaedrus and Laws VIII provide a much clearer account of Plato’s views. In these dialogues, Plato distinguishes between two kinds of (...) love and three kinds of lover. The two kinds of love are fundamentally oriented towards different objects: one kind of love is focused on the body of the beloved and seeks to extract as much bodily pleasure from them as possible, whereas the other kind of love is focused on the soul and seeks to benefit the beloved by improving their character. There is a lover for each kind of love, and a third kind of lover who is torn between these two opposing objects of love. Notably, in the kind of love directed towards the soul, the lovers will not engage in sexual activity. I argue that this is because Plato thinks that the natural function of sex is the procreation of good children and that engaging in such an intensely pleasurable activity risks making the lovers intemperate and lacking in self-control. Thus Plato thinks that the best kind of relationship is one of love (and not just friendship) but is nonetheless non-sexual. (shrink)

Picking up on John Forrester’s (1949–2015) disclosure that he felt ‘haunted’ by the suspicion that Thomas Kuhn’s (1922–96) interests had become his own, this essay complexifies our understanding of both of their legacies by presenting two sites for that haunting. The first is located by engaging Forrester’s argument that the connection between Kuhn and psychoanalysis was direct. (This was the supposed source of his historiographical method: ‘climbing into other people’s heads’.) However, recent archival discoveries suggest that that is incorrect. Instead, (...) Kuhn’s influence in this regard was Jean Piaget (1896–1980). And it is Piaget’s thinking that was influenced directly by psychoanalysis. Psychoanalysis then haunts Kuhn’s thinking through Piaget, and thus Piaget haunts Forrester through Kuhn. To better understand this second site of the haunting—which is ultimately the more important one, given the intent of this special issue—Piaget’s early psychoanalytic ideas are uncovered through their interaction with his early biology and subsequent turn to philosophy. But several layers of conflicting contemporary misunderstandings are first excavated. The method of hauntology is also developed, taking advantage of its origins as a critical response to the psychoanalytic discourse. As a result of adopting this approach, a larger than usual number of primary sources have been unearthed and presented as evidence (including new translations from French originals). Where those influences have continued to have an impact, but their sources forgotten, they have thus been returned. They can then all be considered together in deriving new perspectives of Forrester’s cases/Kuhn’s exemplars/Piaget’s stages. (shrink)

While social epistemology is a diverse field, much of it still understands knowledge as an individual status—albeit an individual status that crucially depends on various social factors (such as testimony). Further, the literature on group knowledge until now has primarily focused on limited, specialized groups that may be said to know this or that as a group. I wish to argue, to the contrary, that all knowledge-attributions ascribe a collective status; and that this follows more or less directly from an (...) essential function of entitlement-ascriptions: Ascriptions of knowledge and entitlement serve a primarily social function in that they facilitate coordination by maintaining consensus around true beliefs, true theories, and truth-producing methodologies. This conclusion will shed light on ways in which traditional theories of knowledge (such as foundationalism and coherentism) fail to capture a central function of our epistemic practice. (shrink)

The 1-consistency of arithmetic is shown to be equivalent to the existence of fixed points of a certain type of update procedure, which is implicit in the epsilon-substitution method.

This is a review of Hossenfelder’s book, Lost in Math: How Beauty Leads Physics Astray. The book gives a breezy exposition of the present situation in fundamental physics, and raises important questions: both about the content of the physics, and the way physics research is organized. I first state my main disagreements. Then, I mostly praise the book: I concentrate on Hossenfelder’s discussion of supersymmetry, naturalness and the multiverse.

Hans Joas is one of the foremost social theorists in Germany today. Based on Joas’s celebrated study of George Herbert Mead, this work reevaluates the contribution of American pragmatism and European philosophical anthropology to theories of action in the social sciences. Joas also establishes direct ties between Mead’s work and approaches drawn from German traditions of philosophical anthropology. Joas argues for adding a third model of action to the two predominant models of rational and normative action—one that emphasizes the creative (...) character of human action. This model encompasses the other two, allowing for a more comprehensive theory of action. Joas elaborates some implications of his model for theories of social movements and social change and for the status of action theory in sociology in the face of competition from theories advanced by Luhmann and Habermas. The problem of action is of crucial importance in both sociology and philosophy, and this book—already widely debated in Germany—will add fresh impetus to the lively discussions current in the English-speaking world.

Many argue that transgenic technology will have wide-ranging implications for farmers in developing nations. A key concern is that competencies may be destroyed by predominantly foreign multinational transgenic technologies, exacerbating problems of social exclusion in the case of subsistence farmers. Conversely, those that fail to adopt the technology may become uncompetitive, particularly in commodity-based export markets. Drawing on interview data conducted in Brazil and supporting data collected in North America, Europe and China, we found that the impact of transgenic technology (...) varies. It has less impact on farmers that adapt the products to their crop systems and environment, and greater negative implications for less formally educated subsistence farmers in consequence of both complexity and compatibility. Earlier attempts at industrializing agriculture through technological innovation led to vastly improved agricultural output and exports, but the benefits of productivity was not equitably distributed [D. Lee: 2005, American Journal of Agricultural Economics 87, 1325-1334], nor was it designed to meet specific local environmental and socioeconomic farmer conditions, exacerbating social exclusion. Multinationals attempting to introduce transgenic technology without considering the broader social and ethical implications will invite resistance. We discuss the implications for policy makers, multinationals and small-scale farmers. (shrink)

It is now more than ten years since the EU FET project ALFEBIITE finished, during which its researchers made original and distinctive contributions to (inter alia) formal models of trust, model-checking, and action logics. ALFEBIITE was also a highly inter-disciplinary project, with partners from computer science, philosophy, cognitive science and law. In this paper, we reflect on the interaction between computer scientists and information and IT lawyers on the idea of the ‘open agent society’. This inspired a programme of research (...) whose investigation into conceptual challenges has carried it from the logical specification of agent societies and dynamic norm-governed systems to self-organising electronic institutions, while developing several technologies for agent-based modelling and complex event recognition. The outcomes of this inter-disciplinary collaboration have also influenced current research into using the open agent society as a platform for socio-technical systems, and other collective adaptive systems. We present a number of research challenges, including the ideas of computational justice and polycentric governance, and explore a number of ethical, legal and social implications. We contend that, in order to address these issues and challenges, the continued inter-disciplinary collaboration between computer science and IT lawyers is critical. (shrink)

This paper examines how the 19th-century British naturalist Alfred Russel Wallace used biogeographical mapping practices to draw a boundary line between Malay and Papuan groups in the colonial East Indies in the 1850s. Instead of looking for a continuous gradient of variation between Malays and Papuans, Wallace chose to look for a sharp discontinuity between them. While Wallace's "human biogeography" paralleled his similar project to map plant and animal distributions in the same region, he invoked distinctive "mental and moral" features (...) as more decisive than physical ones. By following Wallace in the field, we can see his field mapping practices in action -- how he conquered the problem of local particularity in the case of human variation. His experiences on the periphery of expanding European empires, far from metropolitan centers, shaped Wallace's observations in the field. Taking his cues from colonial racial categories and his experiences collaborating with local people in the field, Wallace constructed the boundary line between the Malay and Papuan races during several years of work in the field criss-crossing the archipelago as a scientific collector. This effort to map a boundary line in the field was a bold example of using the practices of survey science to raise the status of field work by combining fact gathering with higher-level generalizing, although the response back in the metropole was less than enthusiastic. Upon his return to Britain in the 1860s, Wallace found that appreciation for observational facts he had gathered in the field was not accompanied by agreement with his theoretical interpretations and methods for doing human biogeography.

Nietzsche’s early philosophy is marked by the sentiment that “only as an aesthetic phenomenon is existence and the world eternally justified (BT §5),” however, in aphorism 313 of The Gay Science, Nietzsche writes: No image of torment: I want to follow Raphael’s example and never paint another image of torment. There are enough sublime things; one does not have to seek out sublimity where it lives in sisterhood with cruelty; anyway, my ambition would find no satisfaction if I wanted to (...) make myself a sublime torturer. Might Nietzsche be suggesting here that the tragic experience drawn from art is no longer a necessary feature of a justification of reality? In this essay, I will argue that aphorism 331 of The Gay Science illustrates that Nietzsche has significantly moved away from the claim that reality can be aesthetically justified as presented in Birth of Tragedy. I will then examine Nietzsche’s doctrine of eternal recurrence. Next, I will offer an interpretation of eternal return that presents a new justification of reality, one in which objective judgment can combat nihilism. I will further argue that, despite Nietzsche’s move away from an aesthetic conception of reality, eternal recurrence is best understood in aesthetic terms, particularly in terms of “theatricality.” Nietzsche conceives of life as a kind of play to be performed eternally, and I will demonstrate how this understanding of recurrence informs the psychological and moral question posed by the demon in Gay Science §341.

This paper gives a technically elementary treatment of some aspects of Hamilton -Jacobi theory, especially in relation to the calculus of variations.

The prime number theorem, established by Hadamard and de la Vallée Poussin independently in 1896, asserts that the density of primes in the positive integers is asymptotic to 1/ln x. Whereas their proofs made serious use of the methods of complex analysis, elementary proofs were provided by Selberg and Erdos in 1948. We describe a formally verified version of Selberg's proof, obtained using the Isabelle proof assistant.

Using Foucault’s conceptual frame from The Archaeology of Knowledge to read Foucault’s late deployment of “spirituality,” this article argues that Foucault’s enigmatic gesture in using this concept reveals a refusal of “rupture” from the Christian pre-modern discourse of “spirit.” Despite attempts to alter the “field of use,” Foucault’s genealogical commitment ensures a Christian continuity in modern discourses of transformation. In a detailed examination of the 1982 Collège de France lectures, the article returns Foucault’s use of “spirituality” to the Alexandrian joining (...) of philosophy and theology and the specificity of Christian practice and belief.

Eugene O'Neill's discarded one-act play Exorcism, a biographical work depicting his suicide attempt in 1911, was described by reviewers at the time as a tragedy, yet it seems strange to characterize the play this way. I argue that from an interpretive point of view, especially focused in Nietzsche's critique of pity, this play can be rightly interpreted as a tragedy. Specific references to Thus Spake Zarathustra and Nietzsche's doctrine of Eternal Return seem to be prevalent in the play, and although (...) Exorcism is not O'Neill's most overtly Nietzschean work, key doctrines of authenticity and self-affirmation are prevalent and provide useful interpretive lenses through which to view the play. I argue that audience members holding Nietzschean convictions about the life well lived will recognize Ned Malloy's failure to actualize such convictions, and Nietzsche's rebuttal of pity makes clear how Ned has failed to actualize those values.
