The philosopher Graham Harman argues that contemporary debates about the nature of reality as such, and about the nature of objects in particular, can be meaningfully applied to social theory and practice. With Immaterialism, he has recently provided a case-based demonstration of how this could happen. But social theorists have compelling reasons to oppose object-oriented social theory’s 15 principles. Fidelity to Harman’s aesthetic foundationalism, and his particular use of serial endosymbiosis theory as a mechanism of social change, constrain the very (...) practices which it is supposed to enable. However, social theory stands to benefit from object-oriented philosophy through what we call posthuman relationism – characterised as a commitment to the reality of the nonhuman, but not divorced from the human. The emphasis in object-oriented social theory on how objects withdraw from cognitive or affective capture and representation needs to be tempered by an equal focus on how objects appeal. (shrink)

In Continental Realism Paul Ennis tackles the rise of realist metaphysics in contemporary continental philosophy. Pitted against the dominant antirealist and transcendental continental hegemony Ennis argues that continental thinking must establish an alliance between metaphysics, speculation, and realism if we are to truly get back to the things themselves.

Responsibility has traditionally been associated with a project of appropriation, understood as the securing of a sphere of mastery for a willful subject, and enframed in a metaphysics of will, causality and subjectivity. In that tradition, responsibility is understood in terms of the subjectum that lies at the basis of the act, as ground of imputation, and opens onto the project of a self-legislation and self-appropriation of the subject. However, one finds in Heidegger and Derrida the reversal—indeed, the deconstruction—of such (...) a tradition, and responsibility is approached instead as an exposure to an inappropriable: assumption of an inappropriable thrownness and finitude for Heidegger, ‘experience of the im-possible’ for Derrida. I will explore how responsibility can be thought from such inappropriable, in an experience that Derrida called ‘ex-appropriation.’ In the process, I will engage the very complex and tortuous relation of Derrida to Heidegger.

The first dictionary dedicated to Quentin Meillassoux and the controversies surrounding his thought Perfect for philosophers just starting to read his work and for those looking to deepen their engagement, this dictionary defines all of the major terms of Meillassoux's work, prefaced by an introduction explaining his importance for the Continental philosophy scene. A-Z entries explain the influence of key figures, from Kant to Heidegger to Derrida, and define the complex terms that Meillassoux uses. The entries are written by the (...) top scholars in the field of speculative realism, often by those that highlight their own disagreements with him. This is more than a dictionary; this is your invitation into one of the liveliest debates in current philosophy. (shrink)

Ever since the turn of the century aesthetics has steadily gained momentum as a central field of study across the disciplines. No longer sidelined, aesthetics has grown in confidence. While this recent development brings with it a return to the work of the canonical authors (most notably Baumgarten and Kant), some contemporary scholars reject the traditional focus on epistemology and theorize aesthetics in its ontological connotations. It is according to this shift that speculative realists have proclaimed aesthetics as "first philosophy" (...) and as speculative in nature. With speculative realism aesthetics no longer necessarily implies human agents. This is in alignment with the general speculative realist framework for thinking all kinds of processes, entities, and objects as free from our all-pervasive anthropocentrism, which states, always, that everything is "for us." This special volume of Speculations explores the ramifications of what could be termed the new speculative aesthetics. In doing so, it stages a three-fold encounter: between aesthetics and speculation, between speculative realism and its (possible) precursors, and between speculative realism and art and literature. (shrink)

With this special volume of Speculations, the editors wanted to challenge the contested term "speculative realism," offering scholars who have some involvement with it a space to voice their opinions of the network of ideas commonly associated with the name.

In this third volume of Speculations, a serial imprint created to explore post-continental philosophy and speculative realism, a wide range of topics are covered, from the philosophy of religion to psychoanalysis to the philosophy of science to gender studies, and in a wide variety of formats (articles, interviews, position pieces, translations, and review essays).

In the Kritik der reinen Vernunft (1781) Kant introduced the transcendental method on a precarious footing and he never shied away from the fact that the transcendental method is structured, and I mean it in the most direct sense possible, aporetically. The aporetic element, the unstable core within Kantian thought, is the distinction between phenomenal and noumenal content in the chapter entitled "On the ground of the distinction [Unterscheidung] of all objects [Gegenstände] in general into phenomena and noumena" (Kant A236/B295-A260/B315). (...) This distinction is noteworthy for introducing into the philosophical tradition the notion of the thing-in-itself [Ding-an-sich]. Depending on your interests this is either the most profound or absurd of ideas in our tradition. I prefer to think of it as the most productive notion in our tradition. We can see its generative function at work almost immediately when it spurred the German idealists into thinking obscenely ingenious thoughts, but the phenomenal-noumenal distinction, hereafter the aporetic distinction, remains an ever-persistent aporia for all continental thinking after Kant. In this article I want to focus on how the aporetic distinction functions in its generative capacity with an emphasis on its ontological rather than epistemological register. Considered as such I claim that it is possible to identify in the aporetic distinction a generative capacity (or logic or function) that is intrinsic to both it and all thought responding to it including, or perhaps especially, the speculative responses.

The context for these interviews was a seminar [Peter Gratton] conducted on speculative realism in the Spring 2010. There has been great interest in speculative realism and one reason Gratton surmise[s] is not just the arguments offered, though [Gratton doesn't] want to take away from them; each of these scholars are vivid writers and great pedagogues, many of whom are in constant contact with their readers via their weblogs. Thus these interviews provided an opportunity to forward student questions about their (...) respective works. Though each were conducted on different occasions, the interviews stand as a collected work, tying together the most classical questions about “realism” to ancillary movements about the non-human in politics, ecology, aesthetics, and video gaming—all to point to future movements in this philosophical area.

Band 13 der psycho-logik widmet sich aus fächerübergreifendem Blickwinkel dem Thema Identität, das in den Sozial- und Geisteswissenschaften zu einem Schlagwort des 20. und 21. Jahrhunderts geworden ist. Gerade die moderne und liberale Gesellschaftsordnung, die uns ungeahnt viel Freiheit ermöglicht hat, charakterisiert ein Patchwork aus Identifikationsangeboten, das zugleich die kollektive und personale Identitätsfindung problematisch macht. Aktuell hat die narrative Theorie die erinnerte und erzählte Lebensgeschichte zum Gründungsort des Selbst erhoben. Sie spielt auch in den Beiträgen dieses Bandes eine prominente Rolle. (...) Es zeigt sich, dass die Identitätskonstruktion ein Prozess ist, in dem sich Identität als etwas Fragiles und Plurales offenbart. Identität ist ein tragisches Spiel zwischen Einheit und Mannigfaltigkeit: Identität(en). Forscher*innen aus Deutschland, Irland und den USA mit ihren Beiträgen aus Literaturwissenschaft, Theologie, Philosophie und Psychologie diskutieren u. a. das Band zwischen Identität und Erinnerung bei Marcel Proust, transsexuelle Identitätskonstruktionen in US-amerikanischen Biopics, den Film als Identitätsbildungsmedium des Publikums, Identitätspolitik(en) am Beispiel des Zugangs zu US-amerikanischen Hochschulen, die Identitätsfindung in Lebensgeschichten und den psychotherapeutischen Umgang mit gebrochenen Identitäten. Fotoarbeiten des Künstlers Hermann Recknagel runden den Band ab. Mit Beiträgen von Michaela I.

This study examined the influence of 7 high school esports developmental programs on student self-regulation, growth mindset, positive youth development, perceived general health and physical activity, and sport behaviour. A total of 188 students originally participated, with 58 participants completing both pre- and post-program information. At baseline, no significant differences were found between youth e-athletes and their aged-matched controls. The analysis for the observation period showed a significant interaction effect for the PYD confidence scale, with post-hoc comparisons showing a significant (...) decrease in the control group from pre- to post assessment whereas the esports group remained the same. Time main effects showed a decrease in the self-regulation motivation factor, PYD connection factor and PA for all participants. Overall, this study showed that students enrolled in their respective school esports program did not differ from those who did not in self-regulation, growth mindset, PYD, perceived health and PA, and sport behaviour. It was likely that all participants showed a decrease in motivation, connection, and PA due to COVID19 lockdown during the study period. This study is the first to investigate the longitudinal impact of student involvement in high school esports and showed that esports participation did not have a negative impact on any health or psychological factors.

In the past few decades, research in the psychology of emotion has benefited greatly from being located in a firm evolutionary framework. It is argued that research in the psychology of mood might attain equal rigour by taking a similar approach. An evolutionary framework for mood research would be based on evolutionary psychology, the main thesis of which is the Massive Modularity Hypothesis. Translating the folk-psychological language of moods into the scientific language of modules might clarify many theoretical questions and (...) provide a sound basis for empirical research. It is argued that such an evolutionary approach would reveal mood to be a much more heterogeneous category than emotion. While the six basic emotions identified by Paul Ekman are probably each subserved by a single module, prototypical moods such as elation, depression, anxiety and irritability are likely to be subserved by a wide range of modules. An evolutionary approach to mood might therefore lead to the elimination of the concept of mood from scientific psychology altogether. (shrink)

continent. 1.2 (2011): 69. In this issue of continent. , which takes as its theme the idea of the moraine, or that which is left behind, we attempt to think, and look beyond that horizon of the possible cataclysm, not in naive ways of hope and gleeful sounds, but in an attempt to present different directions in thought and looking and hearing. Beyond the cataclysm, or within it—or even, precisely anterior to it (anterior to an event not yet happened)—there are (...) new ways of thinking “beyond” already becoming apparent. These ideas are speculative, in a sense irresponsible: Graham Harman writes about Quentin Meillassoux’s God who does not exist now, but may do so in the future while Paul Ennis describes the speculative line backwards to Kant’s distinction between phenomena and noumena. Michael O'Rourke assesses the future of Queer Theory and we are compelled to ask if queer theory is a theory of everything. Karen Spaceinvaders “maps” the brain through sound leaving us to wonder where is the mind, while Phillip Stearns, as though echoing Spaceinvaders’ work, remaps digital photography, creating images from the stray electrical currents in the apparatus. In fiction, Ben Segal gathers the blurbs of the books yet possible. And there is more. And so we proudly offer forth continent. ’s second issue. Whereas issue 1.1 took the theme of isthmus (that which connects land to land, or even, throat to voice), in issue 1.2 we look at what remains after the crushing weight of slow, glacial time has passed. It is geological (which is genealogical) and it is archeological, but it is architectural too. In his later work, Heidegger describes the open ( das offen ) as a lightening ( lichtung ) in terms of a forest clearing which is not only “free for brightness and darkness, but also for resonance and echo, for sounding and diminishing sound. The clearing is the open for everything that is present and absent.” In continent. 1.2, we imagine that clearing, that lichtung which is both a lightening and a clearing, a space of being from which to observe (or even participate in) the coming, very possibly banal, cataclysm(s).

In a well-known paper, Nick Bostrom presents a confrontation between a fictionalised Blaise Pascal and a mysterious mugger. The mugger persuades Pascal to hand over his wallet by exploiting Pascal's commitment to expected utility maximisation. He does so by offering Pascal an astronomically high reward such that, despite Pascal's low credence in the mugger's truthfulness, the expected utility of accepting the mugging is higher than rejecting it. In this article, I present another sort of high value, low credence mugging. This (...) time, the mugger utilises research on existential risk and the long-term potential of humanity to exploit Pascal's expected-utility-maximising descendant. This mugging is more insidious than Bostrom's original as it relies on plausible facts about the long-term future, as well as realistic credences about how our everyday actions could, albeit with infinitesimally low likelihood, affect the future of humanity.

In _Did God Care?_ Dylan Burns offers the first comprehensive survey of providence in ancient philosophy, from Plato to Plotinus, that takes into full account the importance and innovations of early Christian thinkers, including Coptic Gnostic and Syriac sources.

The debate between compatibilists and incompatibilists depends in large part on what ordinary people mean by ‘free will’, a matter on which previous experimental philosophy studies have yielded conflicting results. In Nahmias, Morris, Nadelhoffer, and Turner (2005, 2006), most participants judged that agents in deterministic scenarios could have free will and be morally responsible. Nichols and Knobe (2007), though, suggest that these apparent compatibilist responses are performance errors produced by using concrete scenarios, and that their abstract scenarios reveal the folk (...) theory of free will for what it actually is—incompatibilist. Here, we argue that the results of two new studies suggest just the opposite. Most participants only give apparent incompatibilist judgments when they mistakenly interpret determinism to imply that agents’ mental states are bypassed in the causal chains that lead to their behavior. Determinism does not entail bypassing, so these responses do not reflect genuine incompatibilist intuitions. When participants understand what determinism does mean, the vast majority take it to be compatible with free will. Further results indicate that most people’s concepts of choice and the ability to do otherwise do not commit them to incompatibilism, either, putting pressure on incompatibilist arguments that rely on transfer principles, such as the Consequence Argument. We discuss the implications of these findings for philosophical debates about free will, and suggest that incompatibilism appears to be either false, or else a thesis about something other than what most people mean by ‘free will’.

In recent years, philosophers have identified a number of moral and psychological harms associated with the attention economy (Alysworth & Castro, 2021; Castro & Pham, 2020; Williams, 2018). Missing from many of these accounts of the attention economy, however, is what exactly attention is. As a result of this neglect of the cognitive science of attention, many of these accounts are not empirically credible. They rely on oversimplified and unsophisticated accounts of not only attention, but self- control, and addiction as (...) well. Of note are accounts of the attention economy that rely on the ‘brain disease’ rhetoric of addiction and subsequent control failures (Aylsworth & Castro, 2021; Bhargava & Velasquez, 2021), accounts that rely on a strict dichotomy of top-down vs. bottom-up attention (Williams, 2018; Aylsworth & Castro, 2021), and accounts that construe attention as a limited resource (Williams, 2018). -/- Drawing on recent work from the neuroscience and psychology of attention, I demonstrate the shortcomings of these accounts and sketch a way forward for an empirically grounded account of the attention economy. These accounts tend to uphold strict dichotomies of voluntary control (e.g., compulsion versus choice, dual-process models of self-control, and top-down versus bottom-up) that cannot account for the complexities of attentional control, mental agency, and decision-making. As such, these empirically and conceptually impoverished accounts cannot adequately address the current so-called crisis of attention. To better understand the harms associated with the attention economy, we need an empirically responsible account of the nature and function of attention and mental agency. (shrink)

The standard view in epistemology is that propositional knowledge entails belief. Positive arguments are seldom given for this entailment thesis, however; instead, its truth is typically assumed. Against the entailment thesis, Myers-Schulz and Schwitzgebel (Noûs, forthcoming) report that a non-trivial percentage of people think that there can be propositional knowledge without belief. In this paper, we add further fuel to the fire, presenting the results of four new studies. Based on our results, we argue that the entailment thesis does not (...) deserve the default status that it is typically granted. We conclude by considering the alternative account of knowledge that Myers-Schulz and Schwitzgebel propose to explain their results, arguing that it does not explain ours. In its place we offer a different explanation of both sets of findings—the conviction account, according to which belief, but not knowledge, requires mental assent. (shrink)

A large part of the contemporary phenomenology of medicine has been devoted to accounts of health and illness, arguing that they contribute to the improvement of health care. Less focus has been paid to the issue of prevention of disease and the associated difficulty of adhering to health-promoting behaviours, which is arguably of equal importance. This article offers a phenomenological account of this disease prevention, focusing on how we—as embodied beings—engage with health-promoting behaviours. It specifically considers how we engage with (...) oral hygiene regimens to prevent periodontitis and why we are not good at it. The article suggests that poor adherence to health-promoting behaviours can be explained with reference to the concept of the absent body, because prevention of disease is generally concerned with pre-symptomatic illness experience. The final section contains a discussion of some strategies for the improvement of disease prevention based on this viewpoint. (shrink)

If someone brings about an outcome without intending to, is she causally and morally responsible for it? What if she acts intentionally, but as the result of manipulation by another agent? Previous research has shown that an agent's mental states can affect attributions of causal and moral responsibility to that agent, but little is known about what effect one agent's mental states can have on attributions to another agent. In Experiment 1, we replicate findings that manipulation lowers attributions of responsibility (...) to manipulated agents. Experiments 2–7 isolate which features of manipulation drive this effect, a crucial issue for both philosophical debates about free will and attributions of responsibility in situations involving social influence more generally. Our results suggest that “bypassing” a manipulated agent's mental states generates the greatest reduction in responsibility, and we explain our results in terms of the effects that one agent's mental states can have on the counterfactual relations between another agent and an outcome.

Scientists disagree about which capacities a functional analysis of consciousness should target. To address this disagreement, I propose that a good functional analysis should target the etiological functions of consciousness. The trouble is that most hypotheses about the etiological origins of consciousness presuppose particular functional analyses. In recent years, however, a small number of scientists have begun to offer evolutionary hypotheses that are relatively theory neutral. I argue that their hypotheses can serve an independent standard for evaluating among theories of (...) consciousness. (shrink)

Within philosophy of action, there are three broad views about what, in addition to beliefs, answer the question of “what to do?” and so determine an agent’s motivation: desires, judgments about values/reasons, or states of the will, such as intentions. We argue that recent work in decision theory vindicates the volitionalist. “What to do?” isn’t settled by “what do I value” or “what reasons are there?” Rational motivation further requires determining how to trade off the possibility of a good outcome (...) against the possibility of a bad one—i.e., determining how much of a risk to take. The risk attitudes that embody this tradeoff seem best understood as intentions: as self-governing policies to weight desires or reasons in certain ways. That we need to settle our risk attitudes before making most decisions corroborates Bratman’s claim that self-governing policies are required for resolving impasses of evaluative and normative underdetermination. Moreover, far from being rare or confined to tie-breakings, cases that are underdetermined but for one’s risk attitudes are typical of everyday decision-making. The will is required for most rational action. (shrink)

This paper locates a source of contingency for Leibniz in the fact that God can do otherwise, absolutely speaking. This interpretative line has been previously thought to be a dead-end because it appears inconsistent with Leibniz’s own conception of God, as the ens perfectissimum, or the most perfect being (Adams, 1994). This paper points out that the best argument on offer which seeks to demonstrate this inconsistency fails. The paper then argues that the supposition that God does otherwise implies for (...) Leibniz (at least) that God would not be praiseworthy, which is an absurd implication—or a violation of the principle of sufficient reason (PSR)—but that this is not, strictly speaking, an inconsistency—or a violation of the principle of contradiction (POC). While praiseworthiness is a perfection—and is compossible with God’s other perfections—and so God must instantiate it, this paper argues that, given the nature of praiseworthiness for Leibniz, it in fact makes sense to say that praiseworthiness is merely a contingent perfection of God.

I argue that believing that p implies having a credence of 1 in p. This is true because the belief that p involves representing p as being the case, representing p as being the case involves not allowing for the possibility of not-p, while having a credence that’s greater than 0 in not-p involves regarding not-p as a possibility.

Many contemporary philosophers argue that assertion is governed by an epistemic norm. In particular, many defend the knowledge account of assertion, which says that one should assert only what one knows. Here, I defend a non‐normative alternative to the knowledge account that I call the repK account of assertion. According to the repK account, assertion represents knowledge, but it is not governed by a constitutive epistemic rule. I show that the repK account offers a more straightforward interpretation of the conversational (...) patterns and intuitions that motivate the knowledge account. It does so in terms of ordinary normative principles that philosophers already accept, none of which are constitutive to assertion. I then contend that the repK account is preferable to the knowledge account because it is simpler, its implications are less contentious, and it avoids a problem for normative accounts of assertion recently raised by Peter Pagin. I also argue that the repK account offers a satisfying explanation of selfless assertion, a counterexample to the knowledge account posed by Jennifer Lackey. (shrink)

Jacques Lacan's thinking revolutionised the theory and practice of psychoanalysis and had a major impact in fields as diverse as film studies, literary criticism, feminist theory and philosophy. Yet his writings are notorious for their complexity and idiosyncratic style.

Peter Carruthers argues that the global workspace theory implies there are no facts of the matter about animal consciousness. The argument is easily extended to other cognitive theories of consciousness, posing a general problem for consciousness studies. But the argument proves too much, for it also implies that there are no facts of the matter about human consciousness. A key assumption of the argument is that scientific theories of consciousness must explain away the explanatory gap. I criticize this assumption and (...) point to an alternative strategy for defending scientific theories of consciousness, one that better reflects the ongoing scientific practice. I argue there are introspectable inferential connections from phenomenal concepts to functional concepts that scientists can use to individuate the global workspace in terms of capacities that animals and humans share.

The use of drones in public healthcare is suggested as a means to improve efficiency under constrained resources and personnel. This paper begins by framing drones in healthcare as a social experiment where ethical guidelines are needed to protect those impacted while fully realizing the benefits the technology offers. Then we propose an ethical framework to facilitate the design, development, implementation, and assessment of drones used in public healthcare. Given the healthcare context, we structure the framework according to the four (...) bioethics principles: beneficence, non-maleficence, autonomy, and justice, plus a fifth principle from artificial intelligence ethics: explicability. These principles are abstract which makes operationalization a challenge; therefore, we suggest an approach of translation according to a values hierarchy whereby the top-level ethical principles are translated into relevant human values within the domain. The resulting framework is an applied ethics tool that facilitates awareness of relevant ethical issues during the design, development, implementation, and assessment of drones in public healthcare.

Many philosophers of mind believe that the term 'consciousness' is ambiguous and charge that theoretical work on consciousness is often guilty of conflating distinct concepts of consciousness. I criticize the best arguments for this view -- what I call the multiple concepts view -- and I offer some preliminary support for a new brand of univocalism according to which the concept of consciousness is a cluster concept. In particular I address three lines of evidence for the multiple concepts view: (1) (...) Rosenthal's distinctions between creature consciousness, state consciousness, and transitive consciousness, (2) the argument from theoretical diversity (as I call it), and (3) Block's distinction between access consciousness and phenomenal consciousness.

In this paper I argue for a doctrine I call ?infallibilism?, which I stipulate to mean that If S knows that p, then the epistemic probability of p for S is 1. Some fallibilists will claim that this doctrine should be rejected because it leads to scepticism. Though it's not obvious that infallibilism does lead to scepticism, I argue that we should be willing to accept it even if it does. Infallibilism should be preferred because it has greater explanatory power (...) than fallibilism. In particular, I argue that an infallibilist can easily explain why assertions of ?p, but possibly not-p? (where the ?possibly? is read as referring to epistemic possibility) is infelicitous in terms of the knowledge rule of assertion. But a fallibilist cannot. Furthermore, an infallibilist can explain the infelicity of utterances of ?p, but I don't know that p? and ?p might be true, but I'm not willing to say that for all I know, p is true?, and why when a speaker thinks p is epistemically possible for her, she will agree (if asked) that for all she knows, p is true. The simplest explanation of these facts entails infallibilism. Fallibilists have tried and failed to explain the infelicity of ?p, but I don't know that p?, but have not even attempted to explain the last two facts. I close by considering two facts that seem to pose a problem for infallibilism, and argue that they don't. (shrink)

Noam Chomsky and Frances Egan argue that David Marr’s computational theory of vision is not intentional, claiming that the formal scientific theory does not include description of visual content. They also argue that the theory is internalist in the sense of not describing things physically external to the perceiver. They argue that these claims hold for computational theories of vision in general. Beyond theories of vision, they argue that representational content does not figure as a topic within formal computational theories (...) in cognitive science. I demonstrate that Chomsky’s and Egan’s claims about Marr’s theory are false. Marr’s computational theory contains a mathematical theory of visual content, based on empirical psychophysical evidence. It also contains mathematical descriptions of distal physical surfaces and objects, and of their optic projection to the perceiver. Much computational research on vision contains these types of intentional and externalist components within the formal, mathematical, theories. Chomsky’s and Egan’s claims demonstrate inadequate study and understanding of Marr’s work and other research in this area. Computational theories of vision, by containing empirically based mathematical theories of visual content, to this extent present naturalizations of semantics. (shrink)
