In lieu of an abstract, here is a brief excerpt of the content:The Case against Rational Egoism in Dostoevsky’s Notes from Underground*James P. ScanlanWriting in his own voice, in letters, notebooks, and diaries, Fyodor Dostoevsky frequently attacked the philosophy of the Russian “nihilists,” as he typically called them—Nikolay Chernyshevsky, Dmitry Pisarev, and other representatives of the radical Russian intelligentsia in the third quarter of the nineteenth century. But because Dostoevsky also used fiction to argue against them, if we wish (...) to discern the full contours of his opposition, we must turn to his stories and novels; and there we face the problem of determining to what extent, if any, the statements of his narrators and characters express his own views.This problem is particularly challenging in regard to the radicals’ “Rational Egoism,” to use the label by which the Russian variant of the theory of enlightened egoism came to be known. 1 Dostoevsky’s most sustained and spirited attack on that aspect of “nihilist” philosophy is found in Part One of Notes from Underground (1864), but it is voiced by one of the darkest, least sympathetic of all his characters—the nameless narrator and protagonist known as the Underground Man. Was this repellent creature speaking for Dostoevsky? The Underground Man, moreover, can easily be viewed as a sheer irrationalist whose rejection of Rational Egoism is a tortured emotional outburst with no logical credentials. Robert L. Jackson, in his groundbreaking study of 1958, describes the Underground Man’s thinking at one point as follows: “It is impossible to argue [End Page 549] with the rationalists: reason is on their side. All that remains is irrationally to negate reason.” 2 If those words were to be taken not simply as a moment in Jackson’s rich analysis but as a comprehensive description of the Underground Man’s attitude, it would be senseless to expect philosophically nuanced arguments from him. And we would have no grounds for thinking that Dostoevsky’s own treatment of Rational Egoism went beyond emotional rejection.Critics from Vasily Rozanov to Joseph Frank have debated the Underground Man’s stance toward Rational Egoism and its relation to Dostoevsky’s, with no sign yet of a definitive resolution. Frank’s recent treatment, presented in the third volume of his monumental literary biography of Dostoevsky, offers a helpful history of the dispute as well as his own finely elaborated interpretation of the Underground Man as an irrational opponent of Rational Egoism. 3 Frank reads Notes from Underground as satire, and he contends that the Underground Man is caught in an agonizing self-contradiction: intellectually, he accepts the basic premises of the Rational Egoists’ outlook, such as the denial of free will; but he finds that, “despite the convictions of his reason,” he cannot live with the amoral and dehumanizing implications of those premises, which strip human beings of moral responsibility. 4 From a rational point of view, of course, rejection of the implications should force the Underground Man to reject the premises as well (by the hoary logical law of modus tollendo tolens), and indeed he does at times passionately condemn them. But according to Frank, these condemnations simply show the depth of his predicament: his “intellectual acceptance” of Chernyshevsky’s determinism is conjoined with “simultaneous rejection of it with the entire intuitive-emotional level of personality identified with moral conscience,” causing him to respond irrationally in a multitude of instances. 5 Frank’s Underground Man, then, is an intellectual disciple but an emotional critic of Rational Egoism; and he is triply an irrationalist: his thinking is mired in self-contradiction, he acts irrationally as a result, and his opposition to Rational Egoism has not a rational but an “intuitive-emotional” basis.But where does this leave Dostoevsky? Must we conclude that he, too, is somehow suspended between acceptance and rejection of Rational Egoism and for that reason has created in Notes from Underground a Bakhtinian equilibrium in which neither position is clearly privileged? For Frank, certainly not. It follows from Frank’s analysis that Dostoevsky himself, unlike the Underground [End Page 550] Man, is a fully consistent opponent of Rational Egoism, for that theory is the target of the inverted irony at the core of his satire; “the...

An examination of Russia's philosophical heritage. It extends from the Slavophiles to the philosophers of the Silver Age, from emigre religious thinkers to Losev and Bakhtin and assesses the meaning for Russian culture as a whole.

It is still commonly supposed that Descartes based his argument for the mind-body distinction on the law of the indiscernibility of identicals. I argue that this interpretation is very unlikely to be correct. I explain three contemporary versions of this interpreta- tion and say why I reject it. Basically, use of this law for Descartes’s conclusion would require reference to human bodies or else the supposition, for the purpose of the argument, of reference to human bodies. But at the time (...) Descartes formulated his argument, he would not have allowed either. Instead, I amend a different interpretation which others have found, and briefly defend it against one famous objection. (shrink)

Clement Dore has offered a demonstration that God is possible. This is important because the Ontological Argument shows that if God is possible, it is necessarily true that God exists. Dore’s demonstration parallels Descartes’s Meditation V argument: (roughly) God by definition has all perfections; but (Dore proposes) possible existence is a perfection; therefore, God is possible. However, Leibniz recognized that Descartes’s argument is incomplete, omitting proof that the concept of God is consistent. Dore’s demonstration fails for just this reason. Dore’s (...) defense misses this objection. If the concept of God is consistent, that directly establishes that God is possible, making assumptions about perfections irrelevant. (shrink)

Donald R. Gregory has recently argued that the monk Gaunilo's response to St Anselm's ontological argument succeeds in showing what is fundamentally wrong with any ontological argument, including modern modal versions. He holds that the Gaunilo strategy in fact demonstrates what it alleges, that reasoning which parallels the form and intent ofAnselm's reductio argument can ‘prove’ a priori the existence of quite unacceptable entities.

Systemism and social mechanisms, as articulated by Bunge, are concepts with great potential for application to assessment of research progress. This study will use the conceptual tools made available by systemism and social mechanisms to evaluate the International Crisis Behavior (ICB) Project as a scientific effort toward the greater understanding of crises in world politics. Systemism and social mechanisms are articulated as key concepts in the quest for scientific progress. The goals and basic characteristics of the ICB Project as a (...) scientific venture then are described. The ICB Project is assessed in terms of how well it lives up to standards for scientific progress. Finally, conclusions and ideas about future research are presented. The basic finding of this study is that the ICB Project is quite successful in meeting the standards for scientific progress entailed by the concepts of systemism and social mechanisms. Key Words: scientific progress • international relations • international crises • paradigm. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Feminist Studies 47, no. 1. © 2021 by Feminist Studies, Inc. 147 Eric Andrew James The Representational Necropolitics of Black Women in Zombie Dystopia Video Games Though Stuart Hall defends popular representation as an important terrain of political struggle, he also argues that images of difference are dominated by “racialized regimes of representation” manifest in stereotypes and invisibilities.1 These ensure that marginal identities are reduced, essentialized, and (...) rendered other. One of the most powerful tools for this form of silencing in the popular representation repertoire is the notion of an established genre. In US popular culture, creators and critics alike often position people who experience multiple layers of oppression as constitutively outside the expectations of existing genres. Their absence is attributable not simply to creator racism but also to that genre’s relationships to intersecting categories of difference and domination, such as race and gender. Beginning with the preponderance of representational violence in popular media, this article draws from existing work by feminists of color in order to model a critique of US representational precarity. To illustrate the political tensions in popular US culture, I stage my intervention into a medium whose industry has had particularly fraught struggles with representation: video gaming. There, I focus specifically on 1. Stuart Hall, “The Spectacle of the Other,” in Discourse Theory and Practice: A Reader, ed. Margaret Wetherell, Stephanie Taylor, and Simeon J. Yates. (London: Sage, 2001), 325–44. 148 Eric Andrew James recent attempts to represent Black women, whom the gaming industry has held up as emblematic of difference and diversity. 2 These attempts are marred by predictable disasters and pitfalls. In particular, I discuss how the representational politics of Black women in popular zombie dystopia games repeats a similar violence as the previous silencing of Black women in these spaces. The gaming industry’s struggles with representation in the wake of Gamergate are demonstrative of broader tensions in Black women’s representation in popular media. Thus, while I am focused on video games, I also intend this analysis to reflect on feminist studies of the relationship between genre and representation. I advance existing scholarship on video game representations of Blackness by theorizing violence enacted at the intersections of race, gender, and sexuality in game genres. Specifically, I position this intervention as a point of departure from TreaAndrea M. Russworm’s chapter in Gaming Representation: “Dystopian Blackness and the Limits of Racial Empathy in The Walking Dead and The Last of Us.”3 This chapter provides a compelling critique of the relationship between the dystopian game genre and Black representation, highlighting the lack of self-reflexivity in mass-market representations of Blackness. Expanding this project by taking another look at her objects of study—The Last of Us (2013– 2014) and Telltale’s The Walking Dead (2012)—I argue that taking Black women’s multiple jeopardy as foundational to the zombie dystopia genre offers a deeper look at the grammars of representational violence. My use of multiple jeopardy refers to Deborah K. King’s theorization of how multiple layers of oppression exponentially multiply individual disadvantages. As King describes, “The modifier ‘multiple’ refers not only to several, simultaneous oppressions but to the multiplicative 2.

In the conventional analysis of human behaviour, power and ethics are frequently considered contrary principles, in that power enforces, while ethics elicits a free response. But, as James Mackey forcefully shows, a more adventurous philosophical study of human morality escapes the sense of contraries, and sets us on a quest for the kind of power that liberates human creativity. It then becomes possible to establish the framework for a critical assessment of the kind of power that ought to be (...) operative in the major structures of human society, civil or ecclesiastical, state governments and church hierarchies. Mackey analyses the religious question which then quite naturally emerges, as to whether this Eros-type power so manifest in human society originates from beyond the more empirical structures of churches, states and 'nature'; and the effort to detect the specifically Christian characterisation of an allegedly ultimate power working in us for final well-being finds its natural context.

Far from merely reinvigorating relativism, postmodernism has detected and expressed in our time a powerful nihilating process of which truth and reality itself are the final casualties; and with these morality and religion. Beginning from the theological reaches of philosophy, this book argues that gods played a crucial part in modern philosophy, even when it was most critical of them; that the dominant nihilism of Derrida is really an excessive and misleading outcome of a contemporary philosophy which could otherwise resonate (...) with all that is best in our evolutionary image of the universe; that moralists who turn to art in order to overcome the fact-value version of this deadly dualism do not thereby rule out religion; and that a Christian theology which recognises the evolutionary/historical conditions of faith and revelation is once again producing a theology that builds upon the best of contemporary philosophy and science.

This article uses behavioral theories to develop an ethical decision-making model that describes how psychological factors affect the development of unethical intentions to commit fraud. We evaluate the effects of the dark triad of personality traits on fraud intentions and behaviors. We use a combination of survey results, an experiment, and structural equation modeling to empirically test our model. The theoretical insights demonstrate that psychopathy, Machiavellianism, and narcissism affect different parts of the unethical decision-making process. Narcissism motivates individuals to act (...) unethically for their personal benefit and changes their perceptions of their abilities to successfully commit fraud. Machiavellianism motivates individuals not only to act unethically, but also alters perceptions about the opportunities that exist to deceive others. Psychopathy has a prominent effect on how individuals rationalize their fraudulent behaviors. Accordingly, we find that the dark triad elements act in concert as powerful psychological antecedents to fraud behaviors. (shrink)

This article presents texts recovered by post-processing of multispectral images from the fifth- or sixth-century underwriting of the palimpsest Codex Climaci Rescriptus. Texts identified include the Anonymous II Proemium to Aratus’ Phaenomena, parts of Eratosthenes’ Catasterisms, Aratus’ Phaenomena lines 71–4 and 282–99 and previously unknown text, including some of the earliest astronomical measurements to survive in any Greek manuscript. Codex Climaci Rescriptus also contains at least three astronomical drawings. These appear to form part of an illustrated manuscript, with considerable textual (...) value not merely on the basis of its age but also of its readings. The manuscript undertexts show significant overlap with the Φ Edition, postulated as ancestor of the various Latin Aratea. (shrink)

The world is an untidy place, and the sciences—all of them—reflect this. One source of this untidiness is the relationship between levels of organization. Reducing macrolevels to microlevels—explaining the former in terms of the latter—has met with successes but has never been the whole story. In the biological sciences, there has been much attention lately to the shortcomings of reductionism on the grounds that (i) it changes the subject rather than explaining, (ii) it leads to a myopically molecular view of (...) the biological world, and (iii) the behavior or behaviors of complex systems are often very poorly predicted based solely on their microproperties. It is just for these reasons that biologists of many stripes have called for a move away from reductionism and toward a new kind of biology for the 21st century. But what shape might this new biology take? (shrink)

At least since the late Early Modern period, the Holy Grail of ethics, for many philosophers, has been to say how ethical values could have a kind of protagorean objectivity: values are to be both fully objective as values and yet depend on us by their very nature. More than any other contemporary foundational approach it is “constructivist” theories, such as those due to Rawls, Scanlon, and Korsgaard, which have consciously sought to explain how protagorean objectivity is a real possibility. (...) Yet there remains considerable uncertainty about what the various versions of constructivism have in common, what, if anything, “constructivism” as a general approach is supposed to accomplish, and whether, if it is a general approach, it amounts to a distinctive foundational view.

There is growing evidence that some individuals engage in both self-harm and aggression during the course of their lifetime. The co-occurrence of self-harm and aggression is termed dual-harm. Individuals who engage in dual-harm may represent a high-risk group with unique characteristics and pattern of harmful behaviours. Nevertheless, there is an absence of clinical guidelines for the treatment and prevention of dual-harm and a lack of agreed theoretical framework that accounts for why people may engage in this behaviour. The present work (...) aimed to address this gap in the literature by providing a narrative review of previous research of self-harm, aggression and dual-harm, and through doing so, presenting an evidence-based theory of dual-harm – the cognitive-emotional model of dual-harm. This model draws from previous studies and theories, including the General Aggression Model, diathesis-stress models and emotional dysregulation theories. The cognitive-emotional model highlights the potential distal, proximal and feedback processes of dual-harm, the role of personality style and the possible emotional regulation and interpersonal functions of this behaviour. In line with our theory, various clinical and research implications for dual-harm are suggested, including hypotheses to be tested by future studies. (shrink)

W. V. Quine calls some general methods of science maxims: general defeasible principles that call on us to approximate, maximize, or minimize a state and that are interpreted and weighed in context-sensitive ways. On my reading, his empiricism asks us to maximize accepting overall theories empirically equivalent to ours but to minimize accepting sentences that both do not affect the empirical content of our overall theory and do not simplify our overall theory. His naturalism asks us to maximize accepting sentences (...) that are solely supported by standards that support our best current scientific theory. Drawing on the Quine archive at Houghton Library at Harvard, I support and apply these interpretations by investigating his rapidly evolving later work on empirical content and empirical equivalence, including some of his views on translation in this later work and his vacillation between what he calls the ecumenical and sectarian attitudes.

We investigated, experimentally, the contention that the folk view, or naïve theory, of time, amongst the population we investigated is dynamical. We found that amongst that population, ~ 70% have an extant theory of time that is more similar to a dynamical than a non-dynamical theory, and ~ 70% of those who deploy a naïve theory of time deploy a naïve theory that is more similar to a dynamical than a non-dynamical theory. Interestingly, while we found stable results across our (...) two experiments regarding the percentage of participants that have a dynamical or non-dynamical extant theory of time, we did not find such stability regarding which particular dynamical or non-dynamical theory of time they take to be most similar to our world. This suggests that there might be two extant theories in the population—a broadly dynamical one and a broadly non-dynamical one—but that those theories are sufficiently incomplete that participants do not stably choose the same dynamical theory as being most similar to our world. This suggests that while appeals to the ordinary view of time may do some work in the context of adjudicating disputes between dynamists and non-dynamists, they likely cannot do any such work adjudicating disputes between particular brands of dynamism.

This paper empirically investigates one aspect of the folk concept of time by testing how the presence or absence of directedness impacts judgements about whether there is time in a world. Experiment 1 found that dynamists, showed significantly higher levels of agreement that there is time in dynamically directed worlds than in non-dynamical non-directed worlds. Comparing our results to those we describe in Latham et al., we report that while ~ 70% of dynamists say there is time in B-theory worlds, (...) only ~ 45% say there is time in C-theory worlds. Thus, while the presence of directedness makes dynamists more inclined to say there is time in a world, a substantial subpopulation of dynamists judge that there is time in non-directed worlds. By contrast, a majority of non-dynamists judged that there was time in both growing block worlds and C-theory worlds, with no significant differences between the means. Experiment 2 found that when participants are only presented with non-dynamical worlds—namely, a directed world and a non-directed world—they report significantly higher levels of agreement that there is time in B-theory worlds. However, the majority of participants still judge that there is time in C-theory worlds. We conclude that while the presence of directedness bolsters judgements that there is time, most people do not judge it to be necessary for time. (shrink)

It has widely been assumed, by philosophers, that most people unambiguously have a phenomenology as of time passing, and that this is a datum that philosophical theories must accommodate. Moreover, it has been assumed that the greater the extent to which people have said phenomenology, the more likely they are to endorse a dynamical theory of time. This paper is the first to empirically test these assumptions. Surprisingly, our results do not support either assumption. One experiment instead found the reverse (...) correlation: people were more likely to report having passage phenomenology if they endorsed a non-dynamical theory of time. Given that people do not have an unambiguous phenomenology as of time passing, we conclude that this is suggestive evidence in favor of veridical non-dynamism—the view that our phenomenology is veridical, and that it does not unambiguously represent that time passes. Instead, our phenomenology veridically has some quite different content. (shrink)

Recent research (Latham, Miller and Norton, forthcoming) reveals that a majority of people represent actual time as dynamical. But do they, as suggested by McTaggart and Gödel, represent time as essentially dynamical? This paper distinguishes three interrelated questions. We ask (a) whether the folk representation of time is sensitive or insensitive: i.e., does what satisfies the folk representation of time in counterfactual worlds depend on what satisfies it actually—sensitive—or does is not depend on what satisfies it actually—insensitive, and (b) do (...) those who represent actual time as dynamical, represent time in all possible worlds as dynamical—what we call insensitive dynamism—or do they represent time in all possible worlds as dynamical only conditional on the actual world in fact being dynamical—what we call sensitive dynamism and (c) do dynamists and non-dynamists deploy two different representations of time, or deploy the same representation, but disagree about what actually satisfies that representation? We found no evidence that the folk representation of time is sensitive, or that the folk representation of time is essentially dynamical in either sense, though we did find evidence of a shared representation, on which dynamical features are sufficient, but not necessary, for time.

Philosophers have long noted, and empirical psychology has lately confirmed, that most people are “biased toward the future”: we prefer to have positive experiences in the future, and negative experiences in the past. At least two explanations have been offered for this bias: belief in temporal passage and the practical irrelevance of the past resulting from our inability to influence past events. We set out to test the latter explanation. In a large survey, we find that participants exhibit significantly less (...) future bias when asked to consider scenarios where they can affect their own past experiences. This supports the “practical irrelevance” explanation of future bias. It also suggests that future bias is not an inflexible preference hardwired by evolution, but results from a more general disposition to “accept the things we cannot change”. However, participants still exhibited substantial future bias in scenarios in which they could affect the past, leaving room for complementary explanations. Beyond the main finding, our results also indicate that future bias is stake-sensitive and that participants endorse the normative correctness of their future-biased preferences and choices. In combination, these results shed light on philosophical debates over the rationality of future bias, suggesting that it may be a rational response to empirical realities rather than a brute, arational disposition.

The experience of causation is a pervasive product of the human mind. Moreover, the experience of causing an event alters subjective time: actions are perceived as temporally shifted towards their effects [Haggard, P., Clark, S., & Kalogeras, J.. Voluntary action and conscious awareness. Nature Neuroscience, 5, 382-385]. This temporal shift depends partly on advance prediction of the effects of action, and partly on inferential "postdictive" explanations of sensory effects of action. We investigated whether a single factor of statistical contingency could (...) explain both these aspects of causal experience. We studied the time at which people perceived a simple manual action to occur, when statistical contingency indicated a causal relation between action and effect, and when no such relation was indicated. Both predictive and inferential "postdictive" shifts in the time of action depended on strong contingency between action and effect. The experience of agency involves a process of causal learning based on statistical contingency. (shrink)

Sense of agency refers to the sense of initiating and controlling actions in order to influence events in the outside world. Recently, a distinction between implicit and explicit aspects of sense of agency has been proposed, analogous to distinctions found in other areas of cognition, notably learning. However, there is yet no strong evidence supporting separable implicit and explicit components of sense of agency. The so-called ‘Perruchet paradigm’ offers one of the few convincing demonstrations of separable implicit and explicit learning (...) systems. We adopted this approach to evaluate the implicit–explicit distinction in the context of a simple task in which outcomes were probabilistically caused by actions. In line with our initial predictions, we found evidence of a dissociation. We discuss the implications of this result for theories of sense of agency. (shrink)

Empirical evidence shows that people have multiple time-biases. One is near-bias; another is future-bias. Philosophical theorising about these biases often proceeds on two assumptions. First, that the two biases are _independent_: that they are explained by different factors (the independence assumption). Second, that there is a normative asymmetry between the two biases: one is rationally impermissible (near-bias) and the other rationally permissible (future-bias). The former assumption at least partly feeds into the latter: if the two biases were not explained by (...) different factors, then it would be less plausible that their normative statuses differ. This paper investigates the independence assumption and finds it unwarranted. In light of this, we argue, there is reason to question the normative asymmetry assumption. (shrink)

We investigate the processes underlying the feeling of control over one’s actions . Sense of agency may depend on internal motoric signals, and general inferences about external events. We used priming to modulate the sense of agency for voluntary and involuntary movements, by modifying the content of conscious thought prior to moving. Trials began with the presentation of one of two supraliminal primes, which corresponded to the effect of a voluntary action participants subsequently made. The perceived interval between movement and (...) effect was used as an implicit measure of sense of agency. Primes modulated perceived intervals for both voluntary and involuntary movements, but the modulation was greatest for involuntary movements. A second experiment showed that this modulation depended on prime–movement contiguity. We propose that sense of agency is based on a combination of internal motoric signals and external sensory evidence about the source of actions and effects. (shrink)

This paper is an investigation of the relationship between G\"odel's second incompleteness theorem and the well-foundedness of jump hierarchies. It follows from a classic theorem of Spector's that the relation $\{(A,B) \in \mathbb{R}^2 : \mathcal{O}^A \leq_H B\}$ is well-founded. We provide an alternative proof of this fact that uses G\"odel's second incompleteness theorem instead of the theory of admissible ordinals. We then derive a semantic version of the second incompleteness theorem, originally due to Mummert and Simpson, from this result. Finally, (...) we turn to the calculation of the ranks of reals in this well-founded relation. We prove that, for any $A\in\mathbb{R}$, if the rank of $A$ is $\alpha$, then $\omega_1^A$ is the $(1 + \alpha)^{\text{th}}$ admissible ordinal. It follows, assuming suitable large cardinal hypotheses, that, on a cone, the rank of $X$ is $\omega_1^X$. (shrink)

The emergence of shared symbol systems is considered to be a pivotal moment in human evolution and human development. These changes are normally explained by reference to changes in people's internal cognitive processes. We present 2 experiments which provide evidence that changes in the external, collaborative processes that people use to communicate can also affect the structure and organization of symbol systems independently of cognitive change. We propose that mutual‐modifiability—opportunities for people to edit or manipulate each other's contributions—is a key (...) constraint on the emergence of complex symbol systems. We discuss the implications for models of language development and the origins of compositionality. (shrink)
