It has long been believed across languages that the Agent‐First strategy, a comprehension heuristic that maps the first noun onto the agent role, is a general cognitive bias which applies automatically and faithfully to children's comprehension. The present study asks how this strategy interplays with such grammatical cues as the number of overt arguments and the presence of case‐marking in Korean, an SOV language with case‐marking by dedicated markers. To investigate whether and how these (...) cues affect the operation of this strategy, we measure children's comprehension of a transitive construction (with scrambling and omission of sentential components) in a novel experimental setting where arguments and case markers were obscured to varying degrees through acoustic masking. We find that children do not demonstrate the agent‐first interpretation strongly in the noun–verb pattern without case‐marking, showing their uncertainty about the thematic role of the nominal when it is both the only argument in the sentence and lacks case‐marking. They perform significantly better in the patterns with additional cues, the impact of which is asymmetric by age and by the nature of alignment between cues from word order and case‐marking. These findings suggest that, for Korean‐speaking children's comprehension of a transitive construction, the Agent‐First strategy is activated properly only in conjunction with other types of interpretive cues.

Two criticisms of Dutch strategy arguments are discussed: One says that the arguments fail because agents who know the arguments can use that knowledge to avoid Dutch strategy vulnerability, even though they violate the norm in question. The second consists of cases alleged to be counterexamples to the norms that Dutch strategy arguments defend. The principle of Reflection and its Dutch strategy argument are discussed, but most attention is given to the rule of Conditionalization and to (...) Jeffrey's rule for fallible learning. I argue that the first criticism should be rejected, and that the second presents no counterexamples to the rationality of commitment to the rules. (shrink)

Consequentialism is often criticized for rendering morality too pervasive. One somewhat neglected manifestation of this pervasiveness is the obligatory self-benefit objection. According to this objection, act-consequentialism has the counterintuitive result that certain self-benefitting actions turn out, ceteris paribus, to be morally obligatory rather than morally optional. The purposes of this paper are twofold. First, I consider and reject four strategies with which consequentialists might answer the obligatory self-benefit objection. Despite the apparent consequentialist credentials of these answers, none of these (...) strategies is adequate because each fails to justify agents failing to benefit themselves when benefiting themselves would be otherwise required by the imperative that overall good meet a certain threshold. Second, I argue that no plausible consequentialist response to this objection is forthcoming because consequentialism denies the central axiological fact propelling this objection, namely, that the self possesses a normative architecture relating the self as agent and self as patient. This architecture, I propose, justifies the option not to benefit oneself. (shrink)

Recent research on maintaining diversity in parallel problem solving takes into consideration only network structure, without considering the agents’ learning strategies. In this paper, we use a simulation study to extend March’s classic model by using locomotion and assessment as agents’ problem-solving strategies. First, we present a simulation framework that consists of external environment, communication networks, and agents’ learning strategies. Second, based on the framework, we develop March’s model to depict external environment. Third, we introduce four archetypical networks: a (...) regular network, a small-world network, a preferentially attached network, and a totally connected network as agents’ communication structure. Finally, we design three experiments to explore the performance implication of locomotors and assessors under different networks. Results suggest that network structure affects performance more than learning strategy. The more efficient the network is at diffusing knowledge, the better the performance in the short run but the worse in the long run. Locomotors can help keep diversity; a high proportion of locomotors’ team has a better final performance but need more equilibrium time. Furthermore, moderate composition among locomotors and assessors increases costly interaction uncertainty. We discuss the findings’ implications for the regulatory mode and problem-solving literature. (shrink)

Making proper decisions in today’s complex world is a challenging task for decision makers. A promising approach that can support decision makers to have a better understanding of complex systems is agent-based modeling. ABM has been developing during the last few decades as a methodology with many different applications and has enabled a better description of the dynamics of complex systems. However, the prescriptive facet of these applications is rarely portrayed. Adding a prescriptive decision-making aspect to ABM can support (...) the decision makers in making better or, in some cases, optimized decisions for the complex problems as well as explaining the investigated phenomena. In this paper, first, the literature of DM with ABM is inquired and classified based on the methods of integration. Performing a scientometric analysis on the relevant literature lets us conclude that the number of publications attempting to integrate DM and ABM has not grown during the last two decades, while analysis of the current methodologies for integrating DM and ABM indicates that they have serious drawbacks. In this regard, a novel nature-inspired model articulation called optimal agent framework has been proposed to ameliorate the disadvantages and enhance the realization of proper decisions in ABM at a relatively low computational cost. The framework is examined with the Bass diffusion model. The results of the simulation for the customized model developed by OAF have verified the feasibility of the framework. Moreover, sensitivity analyses on different agent populations, network structures, and marketing strategies have depicted the great potential of OAF to find the optimal strategies in various stochastic and unconventional conditions which have not been addressed prior to the implementation of the framework.

The first three sections of this lecture address the need for better historical-materialist theorisations of capitalist competition, capitalist classes and capitalist states, and in particular the institutional dimensions of these – which is fundamental for understanding why and how capitalism has survived into the twenty-first century. The fourth section addresses historical materialism’s under-theorisation of the institutional dimensions of working-class formation, and how this figures in explaining why, despite the expectations of the founders of historical materialism, the working classes (...) have not, at least yet, become capitalism’s gravediggers. While recognising that a better historical materialism along these lines will not necessarily provide us with a gps route to a socialist world beyond capitalism, it does suggest a number of guidelines for socialist strategy, with which the lecture concludes. This includes the need for building new institutions capable of defining, mobilising and representing the working class broadly, as well as recognising that the types of parties that can transform working classes into leading agents of social transformation have yet to be invented. A strategic priority must be to start anew at creating the kinds of working-class political institutions which can rekindle the socialist imagination, and develop the socialist capacities to get there.

Joaquin Segura. Untitled (fig. 40) . 2007 continent. 1.2 (2011): 117-124. The interview that follows is a dialogue between artist and gallerist with the intent of unearthing the artist’s working strategies for a general public. Joaquin Segura is at once an anomaly in Mexico’s contemporary art scene at the same time as he is one of the most emblematic representatives of a larger shift toward a post-national identity among its youngest generation of artists. If Mexico looks increasingly like a foreclosed (...) home burning to the ground, Segura could likely be the one walking away, charred matchstick between thumb and forefinger and shit-eating grin on his face. His corrosive attacks on institutions, ideologies, and power reflect a deep general distrust of authority, increasingly evident within the work of younger Mexican artists. It is perhaps most directly the result of President Calderon’s deeply unpopular war against the cartels but no doubt equally the product of decades upon decades of rampant corruption and errant policy within Mexico. Brett W Schultz (BWS): A recurring—if not dominant—theme within your current work and investigation explores ideological extremism in reaction to some perceived political and economic disenfranchisement, especially that espoused and practiced by right-wing groups in United States. That's exactly why I thought of you when I was approached to contribute a piece to an issue on the subject of the moraine—taken metaphorically here to signify a certain set of beliefs that have resurfaced within mainstream American culture in the wake of a probably over-exaggerated political sea-change, marked by Obama's election. You're a Mexican artist who now lives and works in Guadalajara, far from the border cities where such concerns would seem more likely to be relevant to a contemporary artist; of course, you're even farther from the culture that birthed this nature of extremism. What interests you so intensely about this movement, if we can call it that? Joaquin Segura (JS): I think there are several seminal points that you touch on in this particular question. There's a very specific set of interests that make me address the socio-political issues I've been dissecting through my practice in the last few years. First of all, I don't really consider myself a 'mexican' artist. As I've made clear in the past, I don't really believe in the notion of 'identity' or the idea of 'nation', which I find totally laughable and heartwarmingly passé. I'm convinced that these are totally outdated models of understanding our differences and similarities, expanding our already immense and irreconcilable cultural abysses instead of bringing them together, thus resulting in their total dispersion among the complex and extremely arbitrary weaving of contemporary social nucleii. Pretty much a frankly bad joke, if I may say so. The fact that I live and work in Mexico is a completely random geographical and temporal factor, which of course affects what I think and what I do, but I've chosen not to be limited by this specific circumstance. In the past, while working abroad, I've taken advantage of this preconception of Mexico—to be more exact, pretty much all of Latin America—as one of the last barbaric bastions of western civilization. Totally amusing, if you ask me about it. I consider my practice to be, among other things, a gonzo strategy of deceit: there are quite a few roles you can adopt in this approach that may actually reveal themselves to be a privileged vantage point. In my experience, the gentle savage is one of the most effective ones to establish my standing position. Thus, I'm a mexican artist if I need it to prove my point. If it's not necessary in a specific circumstance, I'm not. Quite simple, I think. Said in other words, it's just an ace I can play to win a particular match. It has worked so far, at least for me. L: Hey, America… , 2009. R: The Inaugural Address , 2009. I am interested in the nature of power and the rise and fall of totalitarian ideological and political apparatuses nowadays. But I guess, going even further, I'm essentially fascinated by the fissures and contradictions that have made these structures spectacularly crumble to the ground. I do believe extreme ideologies have played a crucial role in the globalization of socio-political crisis. In the end, our world is nothing more than a fading monument to all things gone wrong—the inspiring triumph of failure, in every sense. I see this as an exciting parable. And of course, it is an undeniable fact that the US, through their influence in world economy, international policies and general attitude towards the rest of the planet is the largest structure waiting to collapse. I think we are all secretly awaiting that moment of splendor, even americans. It'll be disastrous and as nasty as it can get, but it will also be liberating and incredibly inspirational. Not just because it’s the US but because it'll prove that absolutely everything is susceptible to fall. And not only that, most importantly, it would confirm that radical change may actually be possible and not just one more of the unfulfilled promises modernity has left us to struggle with on our own. BWS: I want to talk first about two of your works in particular: Hey, America... and The Inaugural Address . I feel like your more recent work has a subtle —or even hidden—sinisterness, but these two works are perfect examples of how brutally confrontational your earlier work has been. When we showed Hey, America... at Mexico City's Zona Maco art fair in 2010, there were at least a couple visitors to our stand who were absolutely ready to punch me in my gringo face for having done so. Certainly the shock value of these works is crucial to their central ideas, but can you tell me more about your intentions and how these works relate to your general oeuvre? JS: So funny. Perhaps we do deserve to be punched in the face. I think that's what I'm sometimes looking for, but I hardly ever get it. I do think of such works as some sort of logical trap, a somewhat perverse ambush waiting for someone to walk into head-on. I think what I tried to do with those two specific works, as well as some other past projects, is just emphasize issues or themes that do disturb or make me uneasy and restless. I consider my essential intention a need to make clear that we do not have to look the other way, ignore or forget. We must address, understand and solve these manifestations of senseless violence and absurdity because if we don't confront them this way, they'll end up consuming us. In other words, I do consider these works as a personal need of coming to terms with the nonsense of the world we all are living in. I don't particularly consider myself to be someone with a clear set of beliefs. Perhaps my only certainty would be that everything is there to be denied, demolished and obliterated—even my supposed unquestionability of that particular 'dogma.' My practice is a reflection of that paradox, and I do think that's how these two pieces relate to a wider body of work. Every democratic system and so-called developed contemporary society is deeply flawed on the inside, and that is because each has swept things under the rug. Of course, there's tolerance, good will and eagerness to make a difference but there's also hatred, pain and fear lingering all around. We must learn to relate to both sides of the spectrum. In a way, I approach the themes behind these particular works in what I think to be a non-biased, somewhat 'neutral' way. I do think there's an encryption process going on in the way I work, some sort of formal refinement of this somewhat outrageous content. A digest of infamy, if we can refer to it that way. It is up to the individual experiencing the work to decide which way these pieces lean. They can easily be seen from both positions and I'm ok with that. If you look closely at these works, there's nothing that establishes an unrelenting position—neither support nor rejection. I don't want my personal political views to directly set an agenda for the spectator as that’s essentially propaganda, which is one of the things I absolutely despise. To sum it up, I strive for the spectator to complete the piece in that sense. The work then becomes a reflection of his or her own contradictions, a playground of the mind. I'm interested in achieving a deadpan and deadlock state in the observer. So, in a way, those visitors threatening to beat the shit out of you unconsciously became that particular issue the work is alluding to. Just blind and senseless reaction to god knows what people feel must be defended, the overwhelming virtue of ambiguity. Beautiful. Perhaps you can also think of my practice as a uber-sophisticated and snobbish version of Punk'd. And you wouldn't be far from what I'm trying to convey. Untitled (Disturbance Scenarios #2) . 2010. BWS: To me, an important transitional marker in the overall trajectory of your work is the series, Disturbance Scenarios , which evokes a similar generalized state of panic, paranoia, and impending doom through its incorporation of sensationalist newspaper headlines, yet also suggests this slyly mysterious meta-narrative via the context in which the newspaper itself is placed. How did you arrive at this series and why did you choose photorealistic painting as the medium for it? JS: I consider this series to be a by-product of the process I follow when making work. I spend an important part of my time just doing research, going through documentation and accumulating visual or historical references for the themes or episodes I'm interested in, in that particular moment. These are, of course, valuable assets that connect among themselves in a mysterious and almost undetectable manner, sometimes a few years between one and the other. I've employed similar production strategies in the past, in ongoing series like Random Moments of Urban Decay , in which I document what I consider to be physical traces of ethnic, religious or ideological violence in the form of text graffiti, invisibly scattered in different cities of the world, mostly in the US. Disturbance Scenarios was started in early 2010, following a particularly intense period of traveling here and there that lasted for most of the year. I've always felt compelled by text, as I find quite intriguing the idea of how words can create equally intense evocations of what I call a mental panorama of uneasiness than those produced by aesthetically-charged imagery; of course, if handled right. I have a close relationship to print media—due both to my academic background and to my attraction to its ubiquity and almost unlimited influence, which in the end, is nothing else but power—so I found myself with a growing archive of newspaper headlines snapshots from cities like Melbourne, Auckland, London, and LA. Going through them, I noticed that they had in common a very specific thematic slant: they were all about some sort of conflict: energy crisis, political unrest, local episodes of domestic violence, you name it. So as you very well put it, I felt they all connected through this feeling of anxiety and anguish and I decided to start thinking of them as a body of work. Basically, I felt an interest in creating what I think of as my personal fragmented prefigurements of the end of civilization. There were few elements on the shots that could give away its actual location, geographically speaking, and I liked that. I find this sensation of vagueness and uncertainty quite alluring. The more subtle, the more perverse. The formal resolution of the series—as photo-realistic painting—is linked to my intention of creating distance between me as the artist and the themes I work with. I rarely execute my own work, and that is more a personal choice as I'm more interested in the ideas I mingle with than in the actual outcome of that process, understood as an "art-object" with certain market value. I did some tests with light-jet prints of those snapshots and I found them devoid of that nightmarish, disturbing indistinctness that I felt was so important for them to be able to project the turmoil I experienced upon encountering them and in conceiving of them as a series. So I thought that photorealistic painting would be an interesting resource to play with, as I hardly had worked with that medium before because of my lenient animosity toward painters and their craft. So they were executed like that and I think it turned out to be just right. Homemade (Napalm #2) . 2010. BWS: Though Disturbance Scenarios remains ongoing, it's an interesting contrast to another series of yours, Homemade, which are these beautifully banal photographs of the ingredients used to make improvised explosives. Whereas Disturbance Scenarios still confronts the viewer aggressively with its visual emphasis on loaded texts, in Homemade , you've dropped the surface-level bravado entirely. They're pieces that require explanation to someone not already versed in the fine art of amateur explosive-making. You weren't known for subtlety in your past work; why this change in direction? JS: I'm personally convinced that these are just two angles of the same conceptual preoccupation. I mentioned before my obsession with the idea of encryption. I'm quite enticed by how these processes of translation can politically and semantically alter and deviate purportedly subversive materials such as the ones these works allude to. I do think subversion is futile. I was really troubled by that thought for some time, but I think now I understand that it's not really that important. What is really significant is to elaborate on these alternate views, to envision and refine possible escape routes. It doesn't really matter if they go nowhere, but that is because nothing really matters. A "mute" artwork is a notion that captivates me. When you look at the works you mention, you know there's something off, but it's not fully clear how and why that is. I rely on that insecurity—on that moment of hesitation. And that can also be achieved through an approach like the one I'm now interested in. Let's just call it a smoke screen, a surrogate ruse to get to the same point: to talk about impotence and defeat in contemporary life. The notion that readily accessible information is actually a weapon is a double-edged fallacy: sure, you can make use of whatever resources you can lay your hands on, but that doesn't set you free because freedom is impossible. Still, that doesn't mean you can't blow up stuff during the process, metaphorically or not. I didn't understand the nature of subtlety before. I used to think that you needed to be loud and manifest anger and unconformity in the most aggressive manner possible. Then I finally realized that you can actually permeate and rarify a battleground—because after all, this is low-intensity war—if you actually aim at silently building up the contradictions and making the symbolic value of ideas and acts clash within themselves. Or perhaps it is that I am just getting old. I guess I used to be an angry kid until recently. Now I think of myself as a disenchanted post-teenager, and of course that reflects in my work and my approach to art-making. Kind of a rite of passage and I laugh at it because, overall, it has been overwhelmingly fun. And that doesn't mean that I'm not ready to stick it in someone or something's face again if I feel like it. BWS: You're now taking the subtlety of the Homemade series even further with your newest series, Definitive Reader For a Botched Revolution , in which you photograph a series of politically-charged books side-on, negating their content entirely—essentially reducing them to purely aesthetic objects in which the subject matter is only revealed in the title of the work. Can you talk about the ideas behind this series? Furthermore, is your recent interest in this idea of the "botched revolution" an indication of a general attitudinal or philosophical shift you've since adopted? JS: This new series of works is the logical outcome of a brief period I went through. Probably the last couple years, in which due to a number of circumstances that don't really have to do with my art-making, I was forced to renegotiate my ideas, my beliefs and practically everything that surrounds me. It was quite distressful and turbulent, but in the end, I think it was also almost epiphanic. I came to terms with myself and now I'm calm and serene. That is, of course, my personal take on it but I mention it because I do think it's important to address this shift you mention. The idea of an artwork as a container for latent revelations enthralls me quite a bit. That's how I see these particular works: art as an incendiary agent. It's up to the artist and the spectator to do whatever they please with it. I think the detachment and almost surgical cleanliness from the Definitive Reader series is also my take at poking fun of the way some art is totally innocuous and uncompromising. These images may be pleasing to the eye, but there's something twisted and rotten within them, well hidden beneath. You'll either see it or not, but without a doubt, it will not cancel its presence. This series is intrinsically linked to Homemade . I'm pretty much horsing around with similar ideas and statements here. And well, yes, I do think any revolution is a botched one. There's nothing too heavy about their own downfall. Decay and breakdown are here and will not go away. Perhaps we must learn to embrace them in one way or another, for our own sake. L: Untitled (T.A.Z.). R: Untitled (United States Marine Guidebook of Essential Subjects) . 2011. BWS: Finally, let's discuss the near future. You've got an upcoming solo show at the Sala de Arte Público Siqueiros [SAPS] in Mexico City this summer. What can we expect from that? What else do you have planned? JS: I'll go and get seafood as soon as I'm done with this interview. It's pretty good here in Guadalajara. That's my top priority at this very moment. About my solo project at SAPS, it's due to open in late July. I'm quite looking forward to it. I'm still closely working with the curator on the general feel for the show but I can say that it'll be more of a revision of past works that have not been shown in Mexico City except for a couple pieces. It definitely won't be a showcase for new projects, although we may include one or two previously unseen works. What you can expect is a rereading of what I've been working on during the past few years. In a way, that's exciting to me because for some reason I don't really care about, I'm not that active in Mexico City even though that's where I lived and work for years. I've hardly shown there after my solo project at Yautepec in February of 2010. It'll be nice to see how it all comes together and I'm more thrilled about it because I totally love the space and I think they're doing an excellent job with their programming and its direction. And in a certain way it feels like going back home. About everything else, I need a period to reflect and fully understand what I've been thinking and working on. I've got a few group shows here and there: New York, San Francisco, and Melbourne are the ones happening soon. I will present my censored project Untitled ( Gringo Loco ) as part of the programming of the Museo de Arte de Zapopan in Guadalajara, two years after being escorted at gunpoint from the installation site by police sent by the extreme right-wing mayor of the city, which I found pretty amusing for an otherwise typical Saturday afternoon. I'm also involved in a couple "curatorial" projects. In my case, "curatorial" means that I help put together stuff I like and I'm interested in. One of them will open in late September of 2011 at Arena Mexico Arte Contemporaneo, and I will work with three of whom I consider to be some of the best artists in a lively and active scene such as the one here in Guadalajara. But most importantly, I've been doing heavy research so there are also a number of projects that I've yet to finalize. That'll be my main focus during the rest of the year, even though I really enjoy procrastination. There'll be time for that later. Or maybe not. We'll see.

This paper investigates the leaderless and leader-follower time-varying formation design and analysis problems for a group of networked agents subject to discontinuous communications. Firstly, a leaderless time-varying formation control protocol is proposed via the intermittent control strategy, where the control input of each agent is constructed by the distributed local state information and formation instructions in the communication time unit, but it is zero in the noncommunication time unit. Then, an explicit formulation of the formation center function is (...) determined to describe the formation movement trajectory of the whole networked agents. Leaderless time-varying formation design and analysis with discontinuous communications are given in the form of linear matrix inequalities. Moreover, the main results of the leaderless cases are extended to the leader-follower cases. Finally, two numerical examples are provided to illustrate the theoretical results of leaderless and leader-follower cases, respectively. (shrink)

In this paper, we first propose a simple formal language to specify types of agents in terms of necessary conditions for their announcements. Based on this language, types of agents are treated as ‘first-class citizens’ and studied extensively in various dynamic epistemic frameworks which are suitable for reasoning about knowledge and agent types via announcements and questions. To demonstrate our approach, we discuss various versions of Smullyan’s Knights and Knaves puzzles, including the Hardest Logic Puzzle Ever (HLPE) (...) proposed by Boolos (in Harv Rev Philos 6:62–65, 1996). In particular, we formalize HLPE and verify a classic solution to it. Moreover, we propose a spectrum of new puzzles based on HLPE by considering subjective (knowledge-based) agent types and relaxing the implicit epistemic assumptions in the original puzzle. The new puzzles are harder than the previously proposed ones in the literature, in the sense that they require deeper epistemic reasoning. Surprisingly, we also show that a version of HLPE in which the agents do not know the others’ types does not have a solution at all. Our formalism paves the way for studying these new puzzles using automatic model checking techniques. (shrink)

How can cooperation be achieved between self-interested individuals in commonly-occurring asymmetric interactions where agents have different positions? Should agents use the same strategies that are appropriate for symmetric social situations? We explore these questions through the asymmetric interaction captured in the indefinitely repeated investment game (IG). In every period of this game, the first player decides how much of an endowment he wants to invest, then this amount is tripled and passed to the second player, who finally decides how (...) much of the tripled investment she wants to return to the first player. The results of three evolutionary studies demonstrate that the best-performing strategies for this asymmetric game differ from those for a similar but symmetric game, the indefinitely repeated Prisoner’s dilemma game. The strategies that enable cooperation for the asymmetric IG react more sensitively to exploitation, meaning that cooperation can more easily break down. Furthermore, once cooperation has stopped, it is much more difficult to reestablish than in symmetric situations. Based on these results, the presence of asymmetry in an interaction appears to be an important factor affecting adaptive behavior in these common social situations. (shrink)

This article examines the definitions of literacy in operation in secondary schools, and the relationship between official literacy policy and the practices of the agents responsible for implementing this policy. We trace the history of national 'policy' back to the Language Across the Curriculum movement of the 1970s as it provides an illustrative point of comparison with the first five years of the National Literacy Strategy. Drawing on empirical data which illuminate the views, perceptions and practices of key (...) agents on a number of levels, we critically review the concept of 'school literacy' promoted in government policy, defining it as 'school-centric literacy' and question its ability to facilitate participation in the practices associated with the media and technological literacies which are increasingly a feature of school life. There is evidence of some unplanned effects of the current national policy but also that levels of agency, for literacy teachers in particular, may be rapidly diminishing. (shrink)

In this chapter I discuss Taylor’s claim that strong evaluation is inevitable for human agency: without a framework of strong evaluations human agents would be in a crisis which Taylor calls, perhaps misleadingly, “an identity crisis”. With a broad brush I introduce some of the essential background in first three sections, and scrutinize the inevitability of strong evaluation more closely in the last three sections. I introduce first the distinction between the engaged perspective, which in Taylor’s view provides (...) the correct approach to humans and values, and two kinds of disengaged perspectives (objectivist and subjectivist ones) (2.1). Taylor’s ideal typical distinction (engaged and disengaged) resembles Sellars’s (1963) distinction between manifest and scientific image, but Taylor takes the scientific worldview to be only one objectivist variant of disengaged views: the Cartesian view of mind is detached from the lifeworldly reality, and is a variant of a subjectivist disengaged view. There are many aspects to Taylor’s philosophical anthropology, based on such an engaged perspective. He defends many “human constants” related to humans as social, self-interpreting, embodied language animals. Although here the focus is merely on one of the human constants, namely on the claim that humans are essentially strong evaluators, I give a sketchy account of the essentials of the broader picture in section 2.2. Taylor uses transcendental argumentation in trying to show the inescapability of strong evaluation in human life. I will, following Nicholas Smith’s reconstruction, discuss Taylor’s reasons for adopting such argumentative strategy in relation to this issue, as opposed to socalled ordinary language philosophy, phenomenological description, hermeneutical interpretation, or strict Hegelian dialectics (2.3). The central point is that although we may want to stress the hermeneutical or interpretive nature of being-in-the-world, and the constitutive nature of human self-interpretations, the few human constants are true whether explicitly taken to be true or not: humans are self-interpreting animals, or strong evaluators, even though they may hold opposing theories in their self-interpretations (cf. Abbey 2000, 4). In a sense, Taylor’s label for his claim, which he terms a “transcendental argument”, may seem to make heavy weather of a simple point: without strong evaluation those aspects of life and experience which presuppose strong evaluation would not be possible. These aspects of life include more or less everything that is peculiarly human. The arguments try to bring into focus these dependencies: strong evaluations are inescapable for our lives as humans or as persons, as opposed to “mere” animals. To be fully outside the scope of strong evaluation is to be in a pathological state. Various disengaged theories of humans neglect this. These are theories of human agency, subjectivity, personhood or identity which have ignored this dimension of human life, or have not taken it to be essential. Taylor’s arguments are directed against such views. In this chapter I will clarify the nature of Taylor’s argument by distinguishing different concepts (human agency, personhood, subjectivity, selfhood, and identity) and asking what it is exactly that strong evaluation is necessary for (2.4). The notions of personhood and identity will be discussed in more detail in the next two chapters. The crucial point in Taylor’s argumentation is made by the claim that for someone capable of strong evaluation, the lack of a framework of strong evaluations involves them in a terrible, frightening crisis, an identity-crisis. I will distinguish several meanings of this claim and discuss their validity in 2.5. I suggest that some “identity-crises” are not at all what Taylor has in mind. But the point itself is valid: without a framework of strong evaluations, human agents would be in a state of crisis. In the last section, I defend Taylor’s view against possible counterexamples, posed by Owen Flanagan and Paul Johnston. (shrink)

This dissertation is an interdisciplinary study of scientific change. The undulatory theory of light replaced the emission theory of light in the early nineteenth century, triggering an "optical revolution" and vigorous debates among physicists in Britain from the 1830s to the 1850s. In this study I give the first full account of this extended episode of scientific change, drawing on methods and concepts from history, sociology and philosophy of science. The interdisciplinary account of the episode provides a basis for (...) criticizing the existing models of scientific change in the philosophy of science. ;Previous historical studies of the "optical revolution" pay little attention to the period after the 1830s. Because the cognitive superiority of the undulatory theory had become obvious in the early 1830s, some historians have implicitly assumed that any controversy would soon come to a natural end. I, however, document that intensive debates continued from the 1830s until the end of the 1850s, and that emissionists even enjoyed temporary victories in their fights with undulationists. The narrative reveals the historical complexities of this episode: the debates extended long after the cognitive superiority of the undulatory theory should have become apparent by modern standard, the results of the debates did not necessarily coincide with modern cognitive judgements, and individual agents played decisive roles in determining how long a debate lasted and how it would end. ;On the basis of the historical narrative, I provide a philosophical analysis of the practices of theory appraisal and experiment appraisal that constituted the main theme of the controversy. Instead of merely identifying the criteria of evaluation employed in this episode, I pay special attention to how individual agents actually applied these criteria in concrete situations, what kinds of strategies or tactics they employed for the applications of these criteria, and how they created favorable conditions, both cognitive and social, for successfully applying these criteria. Individual agents' efforts in selecting application strategies and in creating favorable conditions made the practices of appraisal complicated, exhibiting various features that are incomprehensible if we limit ourselves merely to studying the criteria of evaluation. ;I finally discuss a different approach to scientific change. The existing philosophical models of scientific change merely analyze the final product of science--scientific theories, and ignore the impact of social factors and the role of individual agents. I suggest we concentrate on the process of knowledge production, and pay attention to individual agents's practices in this process, as well as to the relevant cognitive and social factors that influence individual agents. Following this new approach, scientific change is understood as an evolution that involves interactions among three elements: theory, experiment, and human agent. (shrink)

It is common for theorists, drawing on P. F. Strawson, to account for morally responsible agency in terms of the nature of the emotions and feelings that characterize our responsibility practices, in terms of the nature of the so-called “reactive attitudes.” Here, I argue against this attitude-based Strawsonian strategy, and I argue in favor of an alternative, which I call the “concern-based Strawsonian strategy.” On this alternative, rather than account for morally responsible agency in terms of the nature (...) of the reactive attitudes, one accounts for such agency in terms of the concern that leaves us susceptible to those attitudes in the first place. This, I believe, is a more promising way to develop the Strawsonian approach than the attitude-based strategy. The concern-based strategy allows us to better countenance the number and variety of the reactive attitudes that characterize our responsibility practices; it shares the attitude-based strategy’s virtues; and it seems to position us to better understand the distinctive social and moral significance associated with being and being regarded as a morally responsible agent.

In the first half of this dissertation, I develop a heuristic methodology for analyzing scientific solutions to the problem of underdetermination. Heuristics are rough-and-ready procedures used by scientists to construct models, design experiments, interpret evidence, etc. But as powerful as they are, heuristics are also error-prone. Therefore, I argue that they key to prudently using a heuristic is the articulation of meta-heuristics---guidelines to the kinds of problems for which a heuristic is well- or ill-suited. Given that heuristics will introduce (...) certain errors into our scientific investigations, I emphasize the importance of a particular category of meta-heuristics involving the search for robust evidence. Robustness is understood to be the epistemic virtue bestowed by agreement amongst multiple modes of determination. The more modes we have at our disposal, and the more these confirm the same result, the more confident can we be that a result is not a mere artifact of some heuristic simplification. Through an analysis of case-studies in the philosophy of biology and clinical trials, I develop a principled method for modeling and evaluating heuristics and robustness claims in a qualitative problem space. The second half of the dissertation deploys the heuristic methodology to address ethical and epistemological issues in the science of clinical trials. To that end, I develop a network model for the problem space of clinical research, capable of representing the various kinds of experiments, epistemic relationships, and ethical justifications intrinsic to the domain. I then apply this model to ongoing research with the antibacterial agent, moxifloxacin, for the treatment of tuberculosis, tracking its development from initially successful and promising in vitro and animal studies to its disappointing and discordant performance across five human efficacy trials. Given this failure to find a robust result with moxifloxacin across animal and human studies, what should researchers now do? While my final analysis of this case does not definitively answer that question, I demonstrate how my methodology, unlike a statistical meta-analysis, helps to clarify the directions for further research.

Viruses have generally been thought of as infectious agents. New data on mimivirus, however, suggests a reinterpretation of this thought. Earth’s biosphere seems to contain many more viruses than previously thought and they are relevant in the maintenance of ecosystems and biodiversity. Viruses are not considered to be alive because they are not free-living entities and do not have cellular units. Current hypotheses indicate that some viruses may have been the result of genomic reduction of cellular life forms. However, new (...) studies relating to the origins of biological systems suggest that viruses could also have originated during the transition from First to the Last Universal Common Ancestor. Within this setting, life has been established as chemical informational system and could be interpreted as a macrocode of multiple layers. The first entity to acquire these features was the First Universal Common Ancestor that evolved to an intermediate ancestral that could be named T-LUCA and be equated to Woese’s concept of progenotes. T-LUCA may have remained as undifferentiated subsystems with viruses-like structures. The net result is that both cellular life forms and viruses shared protein synthesis apparatuses. In short, virus is a strategy of life reached by two paths: T-LUCAs like entities and the reduction of cellular life forms. (shrink)

The aim of this paper is to argue that it is more plausible to approach understanding from a special type of model—the ABS/IBMs models—as a non-explanatory form following some suggestions advanced by Lipton. I will first look to the type of explanation that some authors claimed is disclosed by these models: Weisberg’s analysis of IBMs in ecology and Grüne-Yanoff’s analysis of the Anasazi model. I argue that their analyses fail to show that these models qualify as explanatory understandings. This (...) brings us to Strevens’ “simple view,” which claims the existence of a correct explanation behind any understanding, and his strategy of dismissing the challenges posed by non-explanatory forms. I argue that this strategy incurs damaging costs on his view. In the last part we turn to Khalifa’s critique on Lipton’s proposals and argue that it is based on an unjustified construal of Lipton’s framework. I show how Khalifa’s “argumentative strategy” fails to establish the superiority of actual understanding over possible explanation. (shrink)

Physarum polycephalum, a unicellular and multiheaded slime mould, can form highly efficient networks connecting separated food sources during the process of foraging. These adaptive networks exhibit a unique characteristic in that they are optimized without the control of a central consciousness. Inspired by this phenomenon, we present an efficient exploration and navigation strategy for a swarm of robots, which exploits cooperation and self-organisation to overcome the limited abilities of the individual robots. The task faced by the robots consists in (...) the exploration of an unknown environment in order to find a path between two distant target areas. For the proposed algorithm, we experimentally present robustness tests and obstacle tests conducted to analyse the performance of our algorithm and compare the proposed algorithm with other swarm robot foraging algorithms that also focus on the path formation task. This work has certain significance for the research of swarm robots and Physarum polycephalum. For the research of swarm robotics, our algorithm not only can lead multirobot as a whole to overcome the limitations of very simple individual agents but also can offer better performance in terms of search efficiency and success rate. For the research of Physarum polycephalum, this work is the first one combining swarm robots and Physarum polycephalum. It also reveals the potential of the Physarum polycephalum foraging principle in multirobot systems. (shrink)

In our daily lives, we need to predict and understand others’ behavior in order to navigate through our social environment. Predictions concerning other humans’ behavior usually refer to their mental states, such as beliefs or intentions. Such a predictive strategy is called ‘adoption of the intentional stance.’ In this paper, we review literature related to the concept of intentional stance from the perspectives of philosophy, psychology, human development, culture, and human-robot interaction. We propose that adopting the intentional stance might (...) be a pivotal factor in facilitating social attunement with artificial agents. The paper first reviews the theoretical considerations regarding the intentional stance and examines literature related to the development of the intentional stance across life span. Subsequently, we discuss cultural norms as grounded in the intentional stance, and finally, we focus on the issue of adopting the intentional stance toward artificial agents, such as humanoid robots. At the dawn of the artificial intelligence era, the question of how – and also when – we predict and explain robots’ behavior by referring to mental states is of high interest. The paper concludes with a discussion on ethical consequences of adopting the intentional stance toward robots, and sketches future directions in research on this topic. (shrink)

Non-verbal enrichment in the form of pictures or gesture can support word learning in first and foreign languages. The present study seeks to compare the effects of viewing pictures vs. imitating iconic gestures on learning second language (L2) vocabulary. In our study participants learned L2 words (nouns, verbs, and adjectives) together with a virtual, pedagogical agent. The to-be-learned items were either (i) enriched with pictures, or (ii) with gestures that had to be imitated, or (iii) without any non-verbal (...) enrichment as control. Results showed that gesture imitation was particularly supportive for learning nouns, whereas pictures showed to be most beneficial for memorizing verbs. These findings, suggesting that the type of vocabulary learning strategy has to match with the type of linguistic material to be learned, have important educational implications for L2 classrooms and technology-enhanced tutoring systems.

Definition of the problem: Recent progress in the pharmacological sciences provides a first glimpse of the development of an individual, genotype-based drug therapy in order to improve the efficiency of drug utilization. Genotyping of genetic polymorphisms in genes involved in drug response promises to optimize drug therapy fundamentally by identifying patients for whom a pharmaceutical agent may be effective and safe or contraindicated because of expected adverse drug reactions. Arguments: The new pharmacogenomic treatment strategies raise complex bioethical issues, (...) because genetic screening for drug therapy may identify asymptomatic patients who are at risk for a particular adverse outcome. Thus, pharmacogenomics will affect the relationship between the treating physician and the patient which is traditionally based on privacy, confidentiality, beneficience and non-maleficience. Conclusion: In the article presented some ethical aspects of these new pharmacogenomic approaches concerning the physician-patient relationship are discussed. (shrink)

While this article sets out to advance our knowledge about the characteristics of Nigerian cybercriminals (Yahoo-Boys), it is also the first study to explore the narratives of the Economic and Financial Crimes Commission (EFCC) officers concerning them. It appraises symbolic interactionist insights to consider the ways in which contextual factors and worldview may help to illuminate officers’ narratives of cybercriminals and the interpretations and implications of such accounts. Semi-structured interviews of forty frontline EFCC officers formed the empirical basis of (...) this study and were subjected to a directed approach of qualitative content analysis. While prior studies, for example, indicated that only a group of cybercriminals deploy spiritual and magical powers to defraud victims (i.e. modus operandi), our data analysis extended this classification into more refined levels involving multiple features. In particular, analysis bifurcates cybercriminals and their operations based on three factors: [a] educational-attainment, [b] modus-operandi, and [c] networks-collaborators. Results also suggest that these cybercriminals and their operations are embedded in “masculinity-and-material-wealth”. These contributions thus have implications for a range of generally accepted viewpoints about these cybercriminals previously taken-for-granted. Since these criminals have victims all over the world, insights from our study may help various local and international agencies [a] to understand the actions/features of these two groups of cybercriminals better and develop more effective response strategies. [b] to appreciate the vulnerabilities of their victims better and develop more adequate support schemes. We also consider the limitations of social control agents’ narratives on criminals. (shrink)

What does it mean to be human? This question has made a meteoric career for itself, becoming a focal point of almost every thread of the transhumanist debate. Significant as it is, the question eludes any definitive answer, since it directly engenders an array of related queries. This Special Issue questions our notions of the human being, human subjectivity, superiority and uniqueness, which tend to be underpinned by simplistic and simplifying dichotomies entrenched in western philosophy, science and art. Eclipsed by (...) the hierarchical vision of the world and dualistic metaphysics, the concept of the nonhuman (regardless of its biological form or ontological status) has always been dependent on its paring element (the human) losing its own significance and independent status. By articulating the problems we face in understanding and defining the human and the nonhuman, this Special Issue offers an insight into the current transhumanist discourse. Crossing the boundaries of disciplines and definitions, the contributors propose an assemblage of methodological and conceptual scaffoldings to build on in this project. They seek new ways and analytical strategies to advance the notions of ‘being one and many’ and ‘being-with’, and in doing so, they envision a new world where forging relations and co-existence with nonhuman agents lie at the core of human experience. The editorial gives some insight into the studies and concepts of this issue. (shrink)

This paper presents two formation tracking control strategies for a combined set of single and double integrator agents with an arbitrary undirected communication topology. The first approach is based on the design of distance-based potential functions with interagent collision avoidance using local information about the distance and orientation between agents and the desired trajectory. The second approach adds signed area constraints to the desired formation specification and a control strategy that uses distance as well as area terms is (...) designed to achieve tracking convergence. Numerical simulations show the performance from both control laws. (shrink)

M. B. Hintikka and J. Hintikka claimed that their reconstruction of the ‘Sherlock Holmes sense of deduction’ can “serve as an explication for the link between intelligence and memory”. The claim is vindicated, first for the single-agent case, where the reconstruction captures strategies for accessing the content of a distributed and associative memory; then, for the multi-agent case, where the reconstruction captures strategies for accessing knowledge distributed in a community. Moreover, the reconstruction of the ‘Sherlock Holmes sense (...) of deduction’ allows to conceptualize those strategies as belonging to a continuum of behavioral strategies. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Kings and Gods as Ecological Agents:From Reciprocity to Unilateralism in the Management of Natural ResourcesSimon Simonse (bio)1. IntroductionThe questions this article addresses are as follows: do non-Western societies have a qualitatively better, more balanced relationship with nature than modern Western societies? Can the difference between the two be described in terms of an opposition between a reciprocal and an exploitative relationship? What difference does the Judeo-Christian tradition make in (...) shaping the modern relationship with nature?To answer these questions I will give brief descriptions of the way in which three cultural traditions have structured the relationship between man and nature: societies that are ruled by sacred kings, societies where power over nature is attributed to divinities, and the Old Testament tradition. As cases of sacred kinship, I present ethnographic material taken from my anthropological fieldwork among the Lulubo, Lokoya, and Lotuho peoples from the East Bank of the Nile in Southern Sudan. I will use the term "Eastern Nilotic" as shorthand for this complex of peoples. For the societies where divinities play the central role, I take the Western Nilotic Dinka, Nuer, and Atuot living in the flood plains of the Nile north of the kingship societies.In comparing these three traditions my point of departure is René Girard's analysis of culture as a mechanism to resolve conflict by directing the aggression of the members of society onto a victim and so achieving a new consensus. We shall see that in the kingship societies what we call natural phenomena play an integral part in culturally staging the scapegoat mechanism. They are the stage of human rivalries and their resolution. Among the polytheistic Western Nilotes they are the instrument through which the gods make their power felt and demand attention from humans. In the Old Testament, natural phenomena remain the domain of God's power. Humans should not try to interfere. Their mission is to combat human evil as defined in Mosaic law. [End Page 31]2. Kings as Ecological AgentsThe survival of the communities of the Lokoya and Lulubo on the East Bank of the Nile who traditionally live in well-fortified village-polities, counting in the precolonial period between 1500 and 2500 inhabitants, is dependent on forces that are unpredictable (Simonse 1992). As agriculturists they are dependent on regular rains. However, the rains in their area are erratic and localized. As a result there is always a risk that the harvest may fail. The soil is of varying quality, giving varying yields in different places. The birth rate is another major concern. It determines the security of the community in its relationship to neighboring, frequently hostile, communities. There is the concern for epidemics, crop-eating insects and birds, and root-eating worms. Violent winds may destroy the crop, and lions and leopards may kill humans and cattle. A concern of a different order is the extent of the effectiveness of weapons, spears, and bows and arrows, in assuring security.When adversity affects the community, the first question asked by those affected is that regarding its cause. Frequently the cause is a breach of the social rules: an act of violence and a failure to perform or properly perform a ritual of purification necessitated by the violence. It may also be unconscious resentment on the part of a person or group that feels excluded from benefits enjoyed by others. It may be the cry of a neglected relative. It may be incest. It may be an attack by outsiders.Among the Lulubo and Lokoya, responsibility for the various aspects of the natural environment that can be critical for community survival is allocated to the different clans. In the case of a crisis (drought, infertility) the clan associated with the problem is the target of investigations. The main investigation strategy is to check, one by one, the quarrels in which members of that clan have been involved. When a conflict has been identified, a solution is suggested by way of reconciliation or restitution. Of particular interest are attempts to provoke the responsible clan official. If a settlement of the dispute fails to bring the required result, there will be more rounds of investigation... (shrink)

An important trend in contemporary epistemology centers on elaborating an old idea of pragmatist pedigree: theory selection (and in general the process of changing view and fixing beliefs) presupposes epistemic values. This article focuses on analyzing the case where epistemic values are indeterminate or when the sources of valuation are multiple (epistemic values like coherence and simplicity need not order options in compatible ways). According to the theory that thus arises epistemic alternatives need not be fully ordered by an underlying (...) notion of information-value and therefore the usual economic techniques of optimization cannot be applied in order to compute optimal contractions. But in cases of this sort it is still rational to maximize, i.e. to deem an option as choosable when it is not known to be worse that any other. We present here basic results about a notion of liberal contraction based on maximizing quasi-orderings. This requires the previous solution of some open problems in the theory of rational choice functions, namely a full characterization of choice functions rationalizable in terms of maximization of quasi-transitive relations. We conclude by discussing the problem of what is the adequate feasible set for calculating maximizing solutions for contraction problems and by considering the epistemological roots of some counterexamples against the most fundamental axioms on choice functions (like α). While the first part of the paper shows how economic insights can be used to improve our understanding of the principles of belief formation and change, this final section reverses this strategy by showing the utility of epistemological insights and techniques for providing invariance conditions capable of regulating the applicability of the pure principles of choice.

What do we mean when we say that some group believes something? Do we simply mean that all the members of the group believe it, or are we acknowledging the existence of some kind of group agent? According to Margaret Gilbert, talk about group mental states refers to the specific kind of agreements she calls joint commitments — that is, to collectively believe something means to be committed with others to believe it. In my article, I will first (...) present Gilbert’s approach in more detail but will ultimately show that this approach is problematic and will refute it. I will briefly consider the most common solution to the problems Gilbert’s account faces, which lies in replacing collective beliefs with acceptances, but I will show that this solution will not do either. The solution I will then present will be based on Daniel Dennett’s intentional strategy, which is a method of interpreting the things around us and predicting their behaviour by treating them as rational agents with relevant intentions. I will try to show that all the problematic cases of collective belief can be explained by applying the intentional strategy to the groups in question. (shrink)

Of the six sections composing «The Methodology of Posive Economics», the first one («The Relation between Positive and Normative Economics») is apparently the less discussed in the F53 literature, probably as a result of being the shortest one and the less relevant for the realism issue, all at once. In view of Milton Friedman’s subsequent career as a political preacher, it seems difficult not to wonder whether this first section ruled it the way the other five directed Friedman’s (...) scientific performance. After all, the role of prediction in defining positive economics was already advanced therein: when an economist predicts, her results are «independent of any particular ethical position or normative judgments». This is also why positive economics is a politically relevant discipline: as long as the differences about economic policy –among disinterested citizens– derive only from different predictions about the economic consequences of taking action, these differences could be eliminated by the progress of positive economics. Our plan in this paper is to present, in the first place, the role of political motivations in the development of Friedman’s methodological stance. As we will discuss in §2, Friedman was involved in the policy-making process right from the beginning of his professional career, and could experience at first hand the relevance of economic predictions in generating a consensus not only among politicians or the public opinion, but among the profession itself. Conversely, Friedman could also appreciate how difficult was to reach a consensus on a particular policy when the economists disagreed on its practical consequences. In this respect, as we will see, «The Methodology» attempted at guaranteeing the political efficiency of economic research. However, the sociological turn in science studies suggests to question on what basis can we deem a prediction neutral. Is it simply that economists produce these positive predictions disinterestedly, even while deeply engaged in political debates? In §3, we analyse how Friedman himself produced predictions immediately before «The Methodology» was drafted, and how this procedure lies at the core of his Marshallian approach, which he contrasted to the Walrasian strategy on the grounds of its higher political relevance..

The paper deals with the correlation between the justification of morality and the justifi­cation of utilitarian normative ethics in the two treatises of Jeremy Bentham: An Intro­duction to the Principles of Morals and Legislation and Deontology. In the Introduction, the general requirement of morality (‘promote the good of others’) is considered justified because a) it is integrated into the structure of the principle of utility and only contingent to the concurring principles (the principle of asceticism and the principle of sympathy (...) and antipathy), b) the two concurring principles cannot withstand rational criticism, c) the list of principles is closed. There are two additional strategies to justify morality in the treatise. Bentham claims that the advantages of having a reputation of a trustworthy person are a sufficient reason to hold burdensome obligations. At the same time, he in­sists that an agent cannot persuade other people that her moral judgments are right unless these jugments are grounded in her recognition of the equal non-instrumental value of ev­ery person. In the Deontology, Bentham expands on the second strategy – the identifica­tion of moral virtue (duty) with the correctly understood personal interest of an agent. First, he proposes such a conception of moral virtue (duty) where sacrifices and efforts made by a person of prudence, probity, and beneficence are interpreted as the result of a clash among her own interests. Then, he demonstrates that the system of sanctions (sympathetic, religious, physical, moral, political) peculiar to human societies makes ad­vantages brought by breaches of prudence, probity, and beneficence illusory.

Abstract:Bipolar or related disorders (BoRD) present unique practical and existential problems for people who live with them. All agents experience changes in the things they care about over time. However people living with BoRD face drastic shifts in what seems valuable to them, which upset their longitudinal values (if, indeed, any stable longitudinal values are available in the first place). Navigating these evaluative high seas presents agents living with BoRD with a distinctive existential question, not shared by those on (...) calmer waters. I draw out two contrasting ways in which someone living with BoRD might seek to support their self-determination in these circumstances, by crafting appropriate self care and support regimes. The first strategy involves managing one’s affective episodes so that they do not interrupt one’s plans and long-term agency over time. The second involves a regimen that allows one the greatest degree of freedom in adapting to changes in one’s experiences of value. What distinguishes these sorts of self-determination is the scope at which they are predicated. Although both sorts of self-determination allow an individual to rule themselves, they alter the overall shape of one’s autonomy in quite different ways. (shrink)

An ongoing debate between ‘procedural’ and ‘substantive’ theorists of personal autonomy addresses the following question: should agents have the final say on their own autonomy or should the objective circumstances in which agents live take prevalence when assessing their autonomy? Proceduralists favour the first strategy and substantive theorists restrict more explicitly the conditions under which autonomy is possible. I focus on forms of heteronomy which derive from oppressive circumstances and accept that substantive theorists are correct in contending that (...) (i) forms of oppression common in contemporary liberal societies (e.g. gender or racial oppression) tend to increase heteronomy; and (ii) the heteronomy which derives from social oppression tends to fly below the radar of procedural accounts. Still, I argue that a revised procedural strategy could limit these forms of heteronomy as long as it avoids the injunctions to ‘authenticity’ common in procedural models. I proceed by reconstructing John Christman’s model which, I argue, constitutes the most promising procedural account to assess autonomy under oppression. Christman’s theory, however, needs to be reinforced to ensure self-problematisation in light of a social perspective. I show that the latter is necessary to experience the forms of alienation which are markers of heteronomy according to Christman. (shrink)

The language comprehension system preferentially assumes that agents come first during incremental processing. While this might reflect a biologically fixed bias, shared with other domains and other species, the evidence is limited to languages that place agents first, and so the bias could also be learned from usage frequency. Here, we probe the bias with electroencephalography (EEG) in Äiwoo, a language that by default places patients first, but where sentence-initial nouns are still locally ambiguous between patient or (...) agent roles. Comprehenders transiently interpreted nonhuman nouns as patients, eliciting a negativity when disambiguation was toward the less common agent-initial order. By contrast and against frequencies, human nouns were transiently interpreted as agents, eliciting an N400-like negativity when the disambiguation was toward patient-initial order. Consistent with the notion of a fixed property, the agent bias is robust against usage frequency for human referents. However, this bias can be reversed by frequency experience for nonhuman referents. (shrink)

In this module, I first explore the dialectic that leads to Kant’s substantive moral theory. In the second section, I explicate the roots of Kant’s ethical theory in terms of his attempt to resolve the antinomy of freedom and determinism. Kant’s solution is a Normative Compatibilism that resolves the inconsistency via morality, in general, and self-governance in particular. As noted in our lesson on Yoga, this is a strategy that Yoga endorses, and hence, predates the Kantian approach by (...) over a millennia and a half. Yet, Kant’s approach to Normative Compatibilism is unique to him, and perhaps, more influential. In the third section, I review Kant’s dialectic by which he concludes that The Categorical Imperative is the means by which rational agents resolve this tension by freely determining themselves. In the fourth section, I consider some preliminary objections to Kant’s theory. In the fifth section, I draw some conclusions. (shrink)

The first step in reasoning about actions and change involves reasoning about how the world would evolve if a certain action is executed in a certain state. Most research on this assumes the evolution to be only a single step and focus on formulating the transition function that defines changes between states due to actions. In this paper we consider cases where the evolution is more than just a single change between one state and another. This is manifested when (...) the execution of an action may trigger execution of other actions, or when multiple agents act on the environment following certain strategies. (shrink)

An agent is morally competent if she can respond to moral considerations. There is a debate about whether agents are open to moral blame only if they are morally competent, and Dana Nelkin’s “Psychopaths, Incorrigible Racists, and the Faces of Responsibility” is an important contribution to this debate. Like others involved in this dispute, Nelkin takes the case of the psychopath to be instructive. This is because psychopaths are similar to responsible agents insofar as they act deliberately and on (...) judgments about reasons, and yet psychopaths lack moral competence. Nelkin argues that, because of their moral incompetence, vices such as cruelty are not attributable to psychopaths. It follows that psychopaths are not open to moral blame since their behavior is only seemingly vicious. I have three aims in this reply to Nelkin. First, I respond to her claim that psychopaths are not capable of cruelty. Second, I respond to the related proposal—embedded in Nelkin’s “symmetry argument”—that a “pro-social psychopath” would not be capable of kindness. My responses to these claims are unified: even if the psychopath is not capable of “cruelty,” and the pro-social psychopath is not capable of “kindness,” the actions of these agents can have a significance for us that properly engages our blaming and praising practices. Finally, I argue that Nelkin’s strategy for showing that moral competence is required for cruelty supports a stronger conclusion than she anticipates: it supports the conclusion that blameworthiness requires not just moral competence, but actual moral understanding.

The most serious challenge to Frankfurt-type counterexamples to the Principle of Alternate Possibilities (PAP) comes in the form of a dilemma: either the counterexample presupposes determinism, in which case it begs the question; or it does not presuppose determinism, in which case it fails to deliver on its promise to eliminate all alternatives that might plausibly be thought to satisfy PAP. I respond to this challenge with a counterexample in which considering an alternative course of action is a necessary condition (...) for deciding to act otherwise, and the agent does not in fact consider the alternative. I call this a “buffer case,” because the morally relevant alternative is “buffered” by the requirement that the agent first consider the alternative. Suppose further that the agent’s considering an alternative action—entering the buffer zone—is what would trigger the counterfactual intervener. Then it would appear that PAP-relevant alternatives are out of reach. I defend this counterexample to PAP against three objections: that considering an alternative is itself a morally relevant alternative; that buffer cases can be shown to contain other alternatives that arguably satisfy PAP; and that even if the agent’s present access to PAP-relevant alternatives were eliminated, PAP could still be satisfied in virtue of earlier alternatives. I conclude that alternative possibilities are a normal symptom, but not an essential constituent, of moral agency. (shrink)

Being human while trying to scientifically study human nature confronts us with our most vexing problem. Efforts to explicate the human mind are thwarted by our cultural biases and entrenched infirmities; our first-person experiences as practical agents convince us that we have capacities beyond the reach of scientific explanation. What we need to move forward in our understanding of human agency, Paul Sheldon Davies argues, is a reform in the way we study ourselves and a long overdue break with (...) traditional humanist thinking. Davies locates a model for change in the rhetorical strategies employed by Charles Darwin in _On the Origin of Species_. Darwin worked hard to anticipate and diminish the anxieties and biases that his radically historical view of life was bound to provoke. Likewise, Davies draws from the history of science and contemporary psychology and neuroscience to build a framework for the study of human agency that identifies and diminishes outdated and limiting biases. The result is a heady, philosophically wide-ranging argument in favor of recognizing that humans are, like everything else, subjects of the natural world—an acknowledgement that may free us to see the world the way it actually is.

I first want to thank John Fischer for his generous appraisal of the book, and for his astute and challenging comments on my treatment of the manipulation argument in Chapter 4. Fischer’s core strategy for resisting this argument is a soft-line reply. Soft-liners claim that in some manipulation cases the agent is not morally responsible, and in others he is. A corollary of the soft-line reply is that there is a plausible compatibilist condition on moral responsibility that (...) has not been met in some of the cases. One prominent response of this sort is that a key condition on basic desert moral responsibility is the absence of intentional manipulation or causal determination . This is not the line Fischer takes. In the response he proposes, intentional causal determination is compatible with moral responsibility in Case 2, that is, in what he calls an initial design case, in which the intentional causation, as in Leibniz’s theological determinism, is confined to the beginning of the agent’s life. But in Case 1, where the intentional manipulation is direct and immediate, the agent is not morally responsible. Fischer’s thought is that Plum’s non-responsibility in Case 1 can be accounted for by the conditions on mechanism-ownership, a feature of the compatibilist account of moral responsibility he and Ravizza developed, which, he correctly points out, I neglect in favor of the reasons-responsiveness component.

Agenda Relevance is the first volume in the authors' omnibus investigation of the logic of practical reasoning, under the collective title, A Practical Logic of Cognitive Systems. In this highly original approach, practical reasoning is identified as reasoning performed with comparatively few cognitive assets, including resources such as information, time and computational capacity. Unlike what is proposed in optimization models of human cognition, a practical reasoner lacks perfect information, boundless time and unconstrained access to computational complexity. The practical reasoner (...) is therefore obliged to be a cognitive economizer and to achieve his cognitive ends with considerable efficiency. Accordingly, the practical reasoner avails himself of various scarce-resource compensation strategies. He also possesses neurocognitive traits that abet him in his reasoning tasks. Prominent among these is the practical agent's striking (though not perfect) adeptness at evading irrelevant information and staying on task. On the approach taken here, irrelevancies are impediments to the attainment of cognitive ends. Thus, in its most basic sense, relevant information is cognitively helpful information. Information can then be said to be relevant for a practical reasoner to the extent that it advances or closes some cognitive agenda of his. The book explores this idea with a conceptual detail and nuance not seen the standard semantic, probabilistic and pragmatic approaches to relevance; but wherever possible, the authors seek to integrate alternative conceptions rather than reject them outright. A further attraction of the agenda-relevance approach is the extent to which its principal conceptual findings lend themselves to technically sophisticated re-expression in formal models that marshal the resources of time and action logics and label led deductive systems. Agenda Relevance is necessary reading for researchers in logic, belief dynamics, computer science, AI, psychology and neuroscience, linguistics, argumentation theory, and legal reasoning and forensic science, and will repay study by graduate students and senior undergraduates in these same fields. Key features: relevance action and agendas practical reasoning belief dynamics non-classical logics labelled deductive systems. (shrink)

Researchers often claim that self-control is a skill. It is also often stated that self-control exertions are intentional actions. However, no account has yet been proposed of the skillful agency that makes self-control exertion possible, so our understanding of self-control remains incomplete. Here I propose the skill model of self-control, which accounts for skillful agency by tackling the guidance problem: how can agents transform their abstract and coarse-grained intentions into the highly context-sensitive, fine-grained control processes required to select, revise and (...) correct strategies during self-control exertion? The skill model borrows conceptual tools from ‘hierarchical models’ recently developed in the context of motor skills, and asserts that self-control crucially involves the ability to manage the implementation and monitoring of regulatory strategies as the self-control exercise unfolds. Skilled agents are able do this by means of flexible practical reasoning: a fast, context-sensitive type of deliberation that incorporates non-propositional representations into the formation and revision of the mixed-format intentions that structure self-control exertion. The literatures on implementation intentions and motivation framing offer corroborating evidence for the theory. As a surprising result, the skill of self-control that allows agents to overcome the contrary motivations they experience is self-effacing: instead of continuously honing this skill, expert agents replace it with a different one, which minimizes or prevents contrary motivations from arising in the first place. Thus, the more expert you are at self-control, the less likely you are to use it. (shrink)

We study the logic of strategic ability of coalitions of agents with bounded memory by introducing Alternating-time Temporal Logic with Bounded Memory (ATLBM), a variant of Alternating-time Temporal Logic (ATL). ATLBM accounts for two main consequences of the assumption that agents have bounded memory. First, an agent can only remember a strategy that specifies actions in a bounded number of different circumstances. While the ATL-formula means that coalition C has a joint strategy which will make φ (...) true forever, the ATLBM-formula means that C has a joint strategy which for each agent in C specifies what to do in no more than n different circumstances and which will make φ true forever. Second, an agent has bounded recall—a strategy can only take the last m states of the system into account. We use the logic to study the interaction between strategic ability, bounded number of decisions, bounded recall and incomplete information. We discuss the logical properties and expressiveness of ATLBM, and its relationship to ATL. We show that ATLBM can express properties of strategic ability under bounded memory which cannot be expressed in ATL. (shrink)

I finished the first draft of this lecture just before the NATO bombing campaign against Serbia began — a campaign that provides, I think, a prime example of the failure of international society. A double failure in this case: its political agencies were not able to respond in a timely fashion to the disaster of the former Yugoslavia, and then they were not able to find a more effective form of military intervention. The problem both times wasn't one of (...) organization but of political will, and I am afraid that I won't have much to say in this lecture about how to solve it. No doubt there are organizational structures that lend themselves to swift and strong action in a crisis.But these structures can as easily produce reckless and cruel acts as wise ones, and so we need to limit their powers. And then, properly limited, they may not act at all. This dilemma is an old one, and my way of dealing with it — which, as you will see, is to multiply structures and agents in the hope that somewhere, somehow, someone will do the right thing — will certainly seem inadequate. I concede immediately that I cannot produce an organizational chart showing how a decision to act rightly in international society would be deliberated, and decided, and then resolutely carried out. There is no such procedural or organizational solution; we have to think instead of a political strategy for coping with crises and for creating the sorts of agents that might cope successfully. That's my goal. It doesn't answer to the urgency of the daily news, but these days nothing could answer.I imagine the possible political arrangements of international society as if they were laid out along a continuum marked off according to the degree of centralization. Obviously, there are alternative markings: the recognition and enforcement of human rights could also be measured along a continuum, as could democratization, economic laissez-faire, welfare provision, pluralism, and so on. But I think that focusing on centralization is the best way of opening a discussion of international politics and the quickest way to reach all the other political and moral questions, above all the classical question: what is the best or the best possible regime? What constitutional goals should we set ourselves in an age of globalization?My plan is to present seven possible regimes or constitutions or political arrangements. I will do this discursively, without providing a list in advance, but I do want to list the criteria against which the seven arrangements have to be evaluated: these are their capacity to promote peace, distributive justice, cultural pluralism, and individual freedom. Obviously, within the scope of a single lecture, I will have to deal much too briefly and summarily with some of the arrangements and some of the criteria. This is especially regrettable since the criteria turn out to be inconsistent with, or at least in tension with, one another. So my argument will be complicated, and could be, probably should be, much more so. (shrink)

How might an agent's moral uncertainty affect what they ought to do? One approach posits principles independent of all first-order moral theories to provide impartial guidance to those uncertain about which moral theory is true; a popular candidate is the principle of maximizing expected choiceworthiness (MEC). Another approach focuses on what first-order moral theories themselves might say about the moral implications of moral uncertainty. This paper considers the latter question in the context of consequentialism by exploring how (...) two consequentialist strategies for dealing with non-moral uncertainty could be extended to moral uncertainty. My conclusion is that a consequentialist could plausibly adopt maximizing expected goodness as a standard of rightness, but not MEC, and that neither is likely to be part of the best consequentialist decision procedure. This result refutes the common suspicion that MEC represents a distinctively consequentialist approach to moral uncertainty. (shrink)

Libertarians in the contemporary free will debate find themselves under attack from two angles. They face the challenge of defending the necessity of indeterminism for freedom against the philosophical mainstream position of compatibilism. And second, they are increasingly forced to argue for the very possibility of indeterministic free will, in the face of the so-called luck objection. Many contemporary libertarians try to overcome the second problem by adopting the causal theory of action. We argue that this move at the same (...) time undermines their ability to answer the first challenge. On the basis of this, we suggest that CTA might be a theory of action that is biased towards compatibilism. We thus argue that the best strategy for the libertarian is to insist that intentional action itself requires indeterminism. Recent agent-causal accounts offer a promising way of developing such an alternative libertarianism, but we argue that they currently suffer from problems similar to the ones we identify for the event-causalist. If we are correct, then this has an important implication for the contemporary free will debate: action theory should take centre stage. (shrink)

The recognition of the close relation between the concept of action and the concept of responsibility goes at least as far back as Aristotle. His account of voluntary action could be seen as being the source of two general strategies for understanding the concept of action.1 One such approach is to determine when something is not an action first by studying a variety of interfering conditions. (e) The agent’s ϕing was a mere happening (non-action) iff external forces caused (...) him to ϕ. But Aristotle described those cases as ones where the principle of action is not in the agent,2 generating what might be thought of as a corresponding picture of what it means for a performance to be an action.

We are agents: we can deliberate about what to do, and then act on the basis of that deliberation. We are also capable of normative self-governance: we can identify and respond to reasons as reasons. Many theorists believe that these two capacities are intimately connected. On the basis of this connection they conclude that practical reasoning must be carried out under the guise of a justification. This paper explores two strategies for avoiding that conclusion. The first, which just denies (...) the connection between agency and normative self-governance, is rejected as too costly, since it leaves the normative significance of agency unexplained. The second, which suggests that we can respond to a consideration as a reason without representing it as a reason, seems more promising, but it requires a reductive account of reasons for action. The upshot is that metaethics and action theory are entwined in ways that few have recognized. (shrink)

1. In this exciting and ambitious book, Duncan Pritchard defends a novel conception of perceptual epistemic grounds, which can both be factive and reflectively available to the agent. Pritchard calls this position the ‘holy grail’ of epistemology for its power to undercut two of contemporary epistemology’s most central problems: the epistemic internalism/externalism controversy and radical scepticism. While Pritchard’s book manages to make a convincing case for why one should accept epistemological disjunctivism (ED), the ‘neo-Moorean’ anti-sceptical strategy that he (...) derives from it is less compelling. This is not because ED does not provide us with the materials for a plausible anti-sceptical strategy, however, but rather because Pritchard misidentifies where ED’s real power lies, namely, in its potential to prevent the radical sceptical problem from arising in the first place. If I am right, then there is no need to establish Moore-type anti-sceptical theses with the ground rules for doing so set by scepticism. For once (and as McDowell has maintained) the thought has been undermined that my perceptual epistemic grounds can only ever consist of the ‘highest common factor’ between the ‘good case’ and the ‘bad case’, the traditional route to radical scepticism is blocked.
