Explains, in graphic novel format, the thinking of the most important philosophers in the Western tradition, including Aristotle, Francis Bacon, and Jean-Paul Sartre.

Rene Descartes is the 16th century philosopher who perpetually doubted everything--even his own physical existence!

What are the acceptable limits of scientific investigation and genetic engineering, the rights and wrongs of animal rights, euthanasia and civil disobedience? This book confronts these dilemmas, tracing arguments of moral thinkers, including Socrates, Plato, Aristotle, and brings us up to date with postmodern critics.

Soren Kierkegaard is widely held to be the founder of existentialism. His faith is ironic, playful and passionate, and he wrote like a novelist. This book brilliantly explains his life and thought.

The entire Who's Who of postmodern thought--Derrida, Foucault, Baudrillard, Lyotard and others, can trace their philosophical ancestry to Nietzsche's radical relativism.

I address a question in moral metaphysics: How are conflicts between moral obligations possible? I begin by explaining why we cannot give a satisfactory answer to this question simply by positing that such conflicts are conflicts between rules, principles, or reasons. I then develop and defend the “Dispositional Account,” which posits that conflicts between moral obligations are conflicts between the manifestations of obligating dispositions (obligating powers, capacities, etc.), just as conflicts between physical forces are conflicts between the manifestations of (certain) (...) causal dispositions (causal powers, capacities, etc.). This account combines the so-called “moral forces” interpretation of prima facie obligations with a dispositional moral metaphysic according to which the metaphysical grounds of moral obligations are not rules or laws, but rather real, irreducibly dispositional properties (or powers) of moral agents and patients. My principal aims are to offer a theoretically attractive and suitably metaphysical account of conflicts of obligation, and to show that the dispositional moral metaphysic that grounds the Dispositional Account can explain and accommodate plausible normative views that rule- and law-based alternatives cannot, as well as to answer objections that have been pressed against other accounts of moral conflict (especially Ross’s) that appeal to moral dispositions or forces.

This introduction to a special issue of Topoi introduces and summarises the relationship between three main varieties of 'enactivist' theorising about the mind: 'autopoietic', 'sensorimotor', and 'radical' enactivism. It includes a brief discussion of the philosophical and cognitive scientific precursors to enactivist theories, and the relationship of enactivism to other trends in embodied cognitive science and philosophy of mind.

Ethical challenges in genomic epidemiology are the direct result of novel tools used to confront scientific challenges in the field. An orders-of-magnitude increase in scale of genetic data collection has created the need for establishing diffuse international partnerships, sometimes across developed- and developing-world countries, with ramifications for assigning research ownership, distributing intellectual property rights, and encouraging capacity-building. Meanwhile, the fact that genomic epidemiological research is so far upstream in the pipeline of therapy development has implications for the privacy rights of (...) research participants and for a rigorous definition of valid informed consent, particularly in resource-poor settings. From these scientific underpinnings, we distill out two main categories of ethical issues: (1) How should researchers ensure that the subjects of research are appropriately protected? and (2) What is the structure of an equitable and fair system for distributing the financial and scientific rewards of research? We attempt to delineate the contours of specific problems in each category and propose steps toward solutions with reference to a particular project, known as gMap.net, that focuses on genomic epidemiological studies of malaria.

This article aims to demonstrate how the formation of ethical subjectivity must be considered in conjunction with the techno-politics of secrecy and disclosure, and it proposes an account of the ways in which the technical transition and ‘democratization’ of archival upload/download capacity associated with digital communications fundamentally challenges the existing structure of control over such things as censorship and cultural memory understood in terms of power of recall. It argues that it is against this background and in view of the (...) mediality of communications that the question of responsibility with respect to secrets and their disclosure must ultimately be posed. It seeks to establish the difference between a purely political and an ethico-political understanding of the secrecy/disclosure dyad as this functions, on the one hand, in relation to philosophical inquiry itself and, on the other, in relation to normative representations of informational events, and it contextualizes its theoretical account of this difference in relation to the ‘Wikileaks phenomenon’ viewed as a disclosive event. It examines how ethical subjectivity is formed in relation to ‘information’ and in the wider context of a digital culture of archivization, characterized by the ubiquitous recording of communications of all kinds. Drawing centrally on the ethical philosophy of Emmanuel Levinas, for whom ‘infinite responsibility’ is ‘incarnated’ as the ‘ultimate secret of subjectivity’ in me, and Derrida’s account of both the necessary technicity of the human and the impossibility of ‘saying the event’, it proposes a way of thinking the ethico-techno-politics of secrecy and disclosure in terms of the singularity of the event and the unique responsibility of the ethical Subject in relation to that.

What is it to be an agent? One influential line of thought, endorsed by G. E. M. Anscombe and David Velleman, among others, holds that agency depends on practical rationality—the ability to act for reasons, rather than being merely moved by causes. Over the past 25 years, Velleman has argued compellingly for a distinctive view of agency and the practical rationality with which he associates it. On Velleman’s conception, being an agent consists in having the capacity to be motivated by (...) a drive to act for reasons. Your bodily movements qualify as genuine actions insofar as they are motivated in part by your desire to behave in a way that makes sense to yourself. However, there are at least two distinct ways of spelling out what this drive towards self-intelligibility consists in, both present in Velleman’s work. It might consist in a drive towards intelligibility in causal-psychological terms: roughly, a drive to maximize the rational coherence of your psychological states. Alternatively, it might consist in a drive towards narrative intelligibility: a drive to make your ongoing activity conform to a recognizable narrative structure, where that structure is understood emotionally. Velleman originally saw these options as basically equivalent, but later came to prioritize the drive towards causal-psychological intelligibility over that towards narrative intelligibility. I argue that this gets things the wrong way round—we should instead understand our capacities to render ourselves intelligible in causal-psychological terms as built upon a bedrock of emotionally suffused narrative understanding. In doing so, we resolve several problems for Velleman’s view, and pave the way for an embodied, embedded and affective account of practical rationality and agency. According to the picture that emerges, practical rationality is essential to agency, narrative understanding is essential to practical rationality, and the rhythms and structures patterning the ebb and flow of our emotional lives are essential to narrative understanding.

Many teacher candidates get their first taste of life as a full-time teacher in their practicums, during which they confront a host of challenges, pedagogical and ethical. Because ethics is fundamental to the connection between teachers and students, teacher candidates are often required to negotiate dilemmas in ways that keep with the ethical ideals espoused both by the professional body and the community at large. Presenting the case of a teacher candidate who finds herself emotionally depleted in her devotion to (...) students, we look to the ethics of care and virtue for clarifying insights. Care ethics extols intersubjectivity and reciprocity, while virtue ethics enjoins commitment to a noble ideal for its own sake; both perspectives offer useful insights for our case. We argue that the perspectives and practices of contemplative traditions can facilitate the integration of care and virtue ethics, mitigating the risk of disruption in caring relations while minimizing the possibility of a personal p...

This book gives a descriptive analysis of specific Madhyamika texts. It compares the ideology of Kumarajiva (a translator of the four Madhyamika treatises 400 A.D.) with the ideologies of the three Chinese contemporaries - HuiYuan, Seng-Jui and Seng-Chao. It envisages an intercultural transmission of religious and philosophical ideas from India to China.

The development of immersive media-communication environments, and their theorization in terms of the `haptic', calls for a reconsideration of the relationship between sensuality and the ethics of contact. For the most part, the cultural theorization of the virtual which remains preoccupied with the visual has tended to limit its scope to the paradoxes, politics and ethics of representation. Much of media and cultural studies work, for instance, has adopted, directly or indirectly, the traditional visual and ocularcentric paradigm in its analyses (...) of cultural forms and technologies as these have become integrated into contemporary life. Whilst it has been argued, for instance by Mark Hansen in his recent books, that this paradigm is inadequate to digital media and the developments of human-machine interactions the digital introduces, few comentators have addressed how new developments in immersive sensory media environments bear on the ethics of communication. By way of a reflection on the themes of the tactility of contact and the ethics of touch in the work of Emmanuel Levinas, this article critically evaluates the ethical significance of the `sensory extension' haptic media represent. It identifies and argues against the neo-positivist tendency of Hansen's reliance on the empiricism of the neurosciences whilst locating the resources for an ethics of touch in Levinas' concept of time as `diachrony'.

Social and linguistic perceptions are linked. On one hand, talker identity affects speech perception. On the other hand, speech itself provides information about a talker's identity. Here, we propose that the same probabilistic knowledge might underlie both socially conditioned linguistic inferences and linguistically conditioned social inferences. Our computational–level approach—the ideal adapter—starts from the idea that listeners use probabilistic knowledge of covariation between social, linguistic, and acoustic cues in order to infer the most likely explanation of the speech signals they hear. (...) As a first step toward understanding social inferences in this framework, we use a simple ideal observer model to show that it would be possible to infer aspects of a talker's identity using cue distributions based on actual speech production data. This suggests the possibility of a single formal framework for social and linguistic inferences and the interactions between them. (shrink)

Shows how ethical subjectivity is not based on individual morals but contemporary cultureTaking his lead from the philosophy of Emmanuel Levinas, and engaging with a number of ethical thinkers, Dave Boothroyd addresses a number of key contemporary ethical subjects. In doing so, he reveals how responsibility is grounded in the everyday encounters and situations we are all familiar with.

We present a specific elaboration and partial defense of the claims that cognition is enactive, embodied, embedded, affective and (potentially) extended. According to the view we will defend, the enactivist claim that perception and cognition essentially depend upon the cognizer’s interactions with their environment is fundamental. If a particular instance of this kind of dependence obtains, we will argue, then it follows that cognition is essentially embodied and embedded, that the underpinnings of cognition are inextricable from those of affect, that (...) the phenomenon of cognition itself is essentially bound up with affect, and that the possibility of cognitive extension depends upon the instantiation of a specific mode of skillful interrelation between cognizer and environment. Thus, if cognition is enactive then it is also embodied, embedded, affective and potentially extended. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Rhetoric and Power: An Inquiry into Foucault’s Critique of ConfessionDave TellOn October 10, 1979, Michel Foucault revised his thesis on confession. On that day, some three years after the publication of his magisterial treatment of confession in the first volume of The History of Sexuality, Foucault argued that the Pythagoreans, Stoics, and Epicureans had, before the advent of Christianity, their own practices of confession. Yet these practices, unlike their (...) Christian variants, were not complicit with practices of domination (OS 310, 312). In the context of Foucault’s thought theretofore, in which the confession consistently figured as an essential component in the exercise of modern power, this is a radical shift. In lectures given at both Berkeley and Dartmouth in the fall of 1980, Foucault made similar arguments. On these occasions he argued that Seneca’s De ira constituted a “stoic confession,” the object of which was to enable the subject to “live differently, better, more happily, than other people” (AB 210, 205). Judith Butler captures the gravity of the shift: “In the last years of his life, Foucault returned to the question of confession, reversing his earlier critique in the first volume of the History of Sexuality, where he indicts confession as a forcible extraction of sexual truth, a practice in the service of a regulatory power” (2005, 112).This reversal was short lived. Although Foucault would celebrate ancient Greek techniques of the self for the rest of his life, he would not [End Page 95] long refer to these techniques in terms of confession. Thus, in another reading of De ira, this one in March 1982, Foucault again noted that the Stoics have “confessional practices” that are “very close to what is found in Christianity” (Herm 482). This time, however, he insisted that the Stoic practices were fundamentally different: “However, all these elements seem to me to be profoundly different from what we should call ‘confession’ in the strict, or anyway, spiritual sense of the word” (Herm 365). In The Care of the Self, Foucault again conceded that De ira—what he now called “the most detailed description” of antique practices of the self—looked “at first glance” like a Christian confession, but he again maintained that it is something quite different: “The purpose of the examination is not therefore to discover one’s own guilt, down to its most trifling forms” (CS 61–62). Foucault concluded that the various “discourses of the self”—the confession and the Greek techniques of the self—could not be placed into a single category (see GE 250). Indeed, the “profound difference” (Herm 299) between these two discourses of the self was perhaps Foucault’s most repeated claim of the 1980s (see Herm 222, 237–44, 299, 308; GE 247–48; WS 237; AB 207–8; RFT 27; UP 89; CS 239; SS 5; FI 5, 12; FS 30, 35, 44, 87, 96, 97, 143–45, 147).It is worth asking why Foucault returned so consistently to the distinction between these two discursive forms. This question gains even more relevance for readers of this journal when we remember that, on at least two occasions, Foucault defined one of these forms, the ancient techniques of the self, in terms of its opposition to rhetoric: the techniques of the self, he claimed, are “nonrhetorical” (Herm 368; FS 20). Thus the question that drives this essay is not so much why Foucault attached such importance to the distinction but rather how rhetoric itself might differentiate the confession from the techniques of the self. Stated differently, Foucault’s work on the confession vis-à-vis the technologies of the self provides a valuable opportunity to study the role of rhetoric in Foucault’s thought—not because they are both rhetorical forms but, curiously, because Foucault insists that one is not.In order to foreground the work of rhetoric in Foucault’s thought, I situate his discourses of the self in the context of Nietzsche’s critique of metonymy. Although this may seem arbitrary, it gains initial plausibility from three facts. First, we know that Foucault understood rhetoric in terms of tropes (OT 84; Cooper 1988, 4). Second, we know too that Foucault had a deep... (shrink)

How do questions concerning consciousness and phenomenal experience relate to, or interface with, questions concerning plans, knowledge and intentions? At least in the case of visual experience the relation, we shall argue, is tight. Visual perceptual experience, we shall argue, is fixed by an agent’s direct unmediated knowledge concerning her poise (or apparent poise) over a currently enabled action space. An action space, in this specific sense, is to be understood not as a fine-grained matrix of possibilities for bodily movement, (...) but as a matrix of possibilities for pursuing and accomplishing one’s intentional actions, goals and projects. If this is correct, the links between planning, intention and perceptual experience are tight, while (contrary to some recent accounts invoking the notion of ‘sensorimotor expectations’) the links between embodied activity and perceptual experience, though real, are indirect. What matters is not bodily activity itself, but our practical knowledge (which need not be verbalized or in any way explicit) of our own possibilities for action. Such knowledge, selected, shaped and filtered by the grid of plans, goals, and intentions, plays, we argue, a constitutive role in explaining the content and character of visual perceptual experience.

How should accounts that stress the embodied, embedded and engaged character of human minds accommodate the role of rationality in human subjectivity? Drawing on Matthew Boyle’s contrast between ‘additive’ and ‘transformative’ conceptions of rationality, I argue that contemporary work on embodied cognition tends towards a problematic ‘additivism’ about the relationship between mature human capacities to think and act for reasons, and sensorimotor capacities to skillfully engage with salient features of the environment. Additivists view rational capacities to reason and reflect as (...) a distinct ‘layer’ or ‘storey’ of human cognition, with a normative structure that differs from that of the sensorimotor coping skills which support it. I argue that emphasizing the embodied and engaged character of human minds is better combined with a ‘transformative’ conception of rationality – one which holds that acquiring abilities to give and ask for reasons transforms the normative structure of our unreflective embodied dealings with the environment. And I argue that a transformative embodied cognitive science of human rationality is not only possible, but underway. Integrating existing work on embodied cognition with work on the cultural and developmental contexts that shape human minds suggests how human immersion in culture transforms the structure of sensorimotor engagements by bringing about the communicability and negotiability of the meanings to which those engagements attune us.

The philosophical literature would have us believe that the conservative view on abortion is based on the claim that the fetus is a person from the time of conception. Given the widespread acceptance of this analysis, it comes as something of a surprise to learn that it conflicts with a number of major arguments offered in support of the conservative view. I argue, in the present paper, that a careful examination of these inconsistencies establishes that the personhood analysis is mistaken: (...) the conservative view is based on the natural process of fetal development, not the personhood of the fetus.

I shall characterize normative functionalism and contrast it with its causal counterpart.

Abstract:Although inquiry-based instruction has been a centerpiece of progressive visions of social studies education almost since its inception as a school subject a century ago, teachers often struggle to conceptualize it in ways that make true inquiry possible for their students. In this essay I suggest that social educators strengthen their connection with John Dewey’s pragmatic epistemology as the foundation of inquiry-based teaching in social studies, arguing in support of an approach that holds the promise of advancing goals associated with (...) meaningful democratic citizenship education.

Skepticism about the limits of online learning is as old as online learning itself. As with other technologically-driven innovations in pedagogy, there are deep-seated worries that important educational goods might be effaced or obscured by the ways of teaching and learning that online methods allow. One family of such worries is inspired by reflections on the bodily basis of an important kind of understanding, and skepticism over whether this bodily basis can be inculcated in the absence of actual, flesh-and-blood, classroom (...) interactions. This paper focuses on the ways in which such worries arise in the influential work of Hubert Dreyfus. The negative conclusion for which I argue is that endorsing Dreyfus's Merleau-Pontian picture of the relationship between bodily skill and understanding does not commit us to his general pessimism concerning online learning—bodily, emotional, and interactive dimensions might be essential to learning, but we lack reasons to think that online learning necessarily lacks these dimensions. The negative argument motivates a positive claim: rather than giving up on online learning we should focus on designing courses and pedagogies that scaffold the bodily, affective and interactive dynamics constitutive of understanding in a particular domain.

I argue that the phenomenal properties of conscious visual experiences are properties of the mind-independent objects to which the subject is perceptually related, mediated by the subject's practical understanding of their sensorimotor relation to those properties. This position conjoins two existing strategies for explaining the phenomenal character of perceptual experiences: accounts appealing to perceivers’ limited, non-inferential access to the details of their sensory relation to the environment, and the relationalist conception of phenomenal properties. Bringing these two positions together by emphasizing (...) their sensorimotor common ground allows each one to respond to damaging objections using the resources of the other. The resulting ‘sensorimotor relationalism’ about conscious vision provides a promising schema for explaining phenomenal properties of perceptual states, replacing ‘Hard’ questions with tractable ones about the perceptual relation and its sensorimotor underpinnings.

The transparency of perceptual experience has been invoked in support of many views about perception. I argue that it supports a form of enactivism—the view that capacities for perceptual experience and for intentional agency are essentially interdependent. I clarify the perceptual phenomenon at issue, and argue that enactivists should expect to find a parallel instance of transparency in our agentive experience, and that the two forms of transparency are constitutively interdependent. I then argue that i) we do indeed find such (...) parallels: the way in which an action is directed towards its goal through our bodily movements parallels the way in which an experience is directed towards its object through our perceptual sensation, and ii) reflecting on sensorimotor skills shows why the two instances of transparency are constitutively interdependent. Section 4 gives reasons for generalizing beyond the cases considered so far by applying the enactive view to Kohler's landmark studies of perceptual adaptation. The final section clarifies the form of enactivism to which the previous sections point. The view that emerges is one whereby our perceptual and practical skills are interrelated aspects of a single capacity to have one's mind intentionally directed upon the world. The transparency of experience, on this view, is achieved in virtue of our capacities as agents as much as it is given in virtue of our capacities as perceivers. (shrink)

Inner membranes of mitochondria are extensively folded, forming cristae. The observed overall correlation between efficient eukaryotic ATP generation and the area of internal mitochondrial inner membranes both in unicellular organisms and metazoan tissues seems to explain why they evolved. However, the crucial use of molecular oxygen (O2) as final acceptor of the electron transport chain is still not sufficiently appreciated. O2 was an essential prerequisite for cristae development during early eukaryogenesis and could be the factor allowing cristae retention upon loss (...) of mitochondrial ATP generation. Here I analyze illuminating bacterial and unicellular eukaryotic examples. I also discuss formative influences of intracellular O2 consumption on the evolution of the last eukaryotic common ancestor (LECA). These considerations bring about an explanation for the many genes coming from other organisms than the archaeon and bacterium merging at the start of eukaryogenesis. (shrink)

Meyer and Brancazio make an important distinction between two enactivist projects: “utopian” and “scientific.” I agree that contemporary enactivists would benefit from more clearly distinguishing these projects and their success conditions.
