By focusing on the caloric composition of hunted prey species, optimal foraging research has shown that hunters usually make economically rational prey choice decisions. However, research by meat scientists suggests that the gustatory appeal of wildlife meats may vary dramatically. In this study, behavioral research indicates that Mayangna and Miskito hunters in Nicaragua inconsistently pursue multiple prey types in the optimal diet set. We use cognitive methods, including unconstrained pile sorts and cultural consensus analysis, to investigate (...) the hypothesis that these partial preferences are influenced by considerations of meat flavor. Native informants exhibit high agreement on the relative appeal of different meats. Given the absence of other noteworthy differences between spider monkeys (Ateles geoffroyi) and howler monkeys (Alouatta palliata), the unappealing flavor of howler monkeys seems to be a factor in the partial preference for this species.

A widespread perception is that carnivores are limited by the amount of prey that can be captured rather than their nutritional quality, and thus have no need to regulate macronutrient balance. Contrary to this view, recent laboratory studies show macronutrient‐specific food selection by both invertebrate and vertebrate predators, and in some cases also associated performance benefits. The question thus arises of whether wild predators might likewise feed selectively according to the macronutrient content of prey. Here we review laboratory (...) studies demonstrating the regulation of macronutrient intake by invertebrate and vertebrate predators, and address the question of whether this is likely to also occur in the wild. We conclude that it is highly likely that wild predators select prey or selectively feed on body parts according to their macronutrient composition, a possibility that could have significant implications for ecological and foraging theory, as well as applied wildlife conservation and management.

Provision of additional food supplements for the purpose of biological conservation has been widely researched both theoretically and experimentally. The study of these biosystems is usually done using predator–prey models. In this paper, we consider an additional food provided predator–prey system in the presence of the inhibitory effect of the prey. This model is analyzed in the control parameter space using the control parameters, quality and quantity of additional food. The findings suggest that with appropriate choice (...) of additional food to predators, the biosystem can be controlled and steered to a desirable state. It is also possible to eliminate either of the interacting species. The vital role of the quality and quantity of the additional food in the system dynamics cautions the eco manager on the choice of the additional food for realizing the goal in the biological conservation programme.

Native peoples have often been portrayed as natural conservationists, living a “balanced” existence with nature. It is argued that this perspective is a result of an imprecise operational definition of conservation. Conservation is defined here in contrast to the predictions of foraging theory, which assumes that foragers will behave to maximize their short-term harvesting rate. A behavior is deemed conservation when a short-term cost is paid by the resource harvester in exchange for long-term benefits in the form of sustainable harvests. (...) An example of the usefulness of such an operational definition is presented using data on patch and prey choice decisions of a group of subsistence hunters, the Piro of Amazonian Peru. Results indicate that the area around the Piro village is depleted of prey, and that hunters allocate more time to patches where return rates are highest. This response is consistent with both a conservation strategy and foraging theory. Contrary to the expectation of the conservation strategy, however, hunters do not restrain from pursing opportunistically encountered prey in the depleted areas. The implications for conservation policy are briefly discussed. (shrink)

Anyway, one day, the King summoned the Sage, intending to kill him. -/- The King said, “Wise man, I heard you earn a living by thinking and arguing. Now I give you two options to die.” -/- The Sage said, “Please tell me the choices, Your Majesty.” -/- The King continued, “You live by your tongue, so I will let you say one sentence before you die. If what you say is true, you will die by hanging. If what you say is false, you will die by beheading.” -/- Little did the King know that this was a stupid order. After a short while, the Sage confidently spoke his “last words”, which actually were what saved his life: -/- “Your Majesty, I am about to be beheaded!” -/- ¤ -/- As a “wild animal” going out into life from a young age, my brain spent a lot of time and energy looking for food.

Amplifying Bernard Williams’ critique of the Nietzschean project of a revaluation of values, this paper mounts a critique of the idea that whether values will help us to live can serve as a criterion for choosing which values to live by. I explore why it might not serve as a criterion and highlight a number of further difficulties faced by the Nietzschean project. I then come to Nietzsche's defence, arguing that if we distinguish valuations from values, there is at least (...) one form of the project which overcomes those difficulties. Finally, however, I show that even on this reading, the project must either fall prey to ‘Saint-Just's illusion’ or fall back into the problems it was supposed to escape. This highlights important difficulties faced by the Nietzschean project and its descendants while also explaining why Williams, who was so Nietzschean in other respects, remained wary of the revaluation of values as a project.

From the outset, critical social theory has sought to diagnose people’s participation in their own oppression, by revealing the roots of irrational and self-undermining choices in the complex interplay between human nature, social structures, and cultural beliefs. As part of this project, Ideologiekritik has aimed to expose faulty conceptions of this interplay, so that the objectively pathological character of what people are “freely” choosing could come more clearly into view. The challenge, however, has always been to find a way of (...) doing this without arrogantly assuming special access to what is good for people. And this danger of paternalism is one to which social theorists have all too often fallen prey. In this brief essay, I focus on contemporary instances of clearly self-defeating behavior in contexts of complex choices. I begin by discussing a recent attempt to diagnose and solve these failures of choices, namely the public policy recommendations of behavioral economist Richard Thaler and reform-minded legal theorist Cass Sunstein. Their influential “libertarian paternalist” approach is particularly interesting, both in what it includes (attention to the socially constructed nature of choice situations and the roots of the problems in human nature) and in what it leaves out (an understanding of the social construction of human nature and an adequate appreciation of the value of autonomy). After discussing it, I consider a broadly perfectionist alternative, to the effect that the problem lies in a failure to adequately appreciate the importance of developing autonomy. I then turn to sketching the outlines of a new approach, based on the concept of “autonomy gaps,” which approaches overly demanding policies in relational and action-theoretical terms. In the final section, I show how this provides the basis for an analysis both in terms of a critique of ideology and of social pathology. (shrink)

Background Patients with unmet medical needs sometimes resort to non-standard treatment options, including the use of unapproved, investigational drugs in the context of clinical trials, compassionate use or named-patient programs. The views and experiences of patients with unmet medical needs regarding unapproved, investigational drugs have not yet been examined empirically. Methods In this qualitative study, exploratory interviews and focus groups were held with patients with chronic or life-threatening diseases, about topics related to non-standard treatment options, such as the search for (...) non-standard treatment options, patients’ views of the moral obligations of doctors, and the conditions under which they would or would not wish to use non-standard treatment options, including expanded access to unapproved, investigational drugs. Results Respondents had very little knowledge about and/or experience with existing opportunities for expanded access to investigational drugs, although some respondents were actively looking for non-standard treatment options. They had high expectations of their treating physicians, assuming them to be aware of non-standard treatment options, including clinical trials elsewhere and expanded access programs, and assuming that they would inform their patients about such options. Respondents carefully weighed the risks and potential benefits of pursuing expanded access, citing concerns related to the scientific evidence of the safety and efficacy of the drug, side effects, drug-drug interactions, and the maintaining of good quality of life. Respondents stressed the importance of education and assertiveness to obtain access to good-quality health care, and were willing to pay out of pocket for investigational drugs. Patients expressed concerns about equal access to new and/or non-standard treatment options. Conclusion When the end of a standard treatment trajectory comes into view, patients may prefer that treating physicians discuss non-standard treatment options with them, including opportunities for expanded access to unapproved, investigational drugs. Although our respondents had varying levels of understanding of expanded access programs, they seemed capable of making well-considered choices with regard to non-standard treatment options and had realistic expectations with regard to the safety and efficacy of such options. Dutch patients might be less likely to fall prey to false hope than often presumed. (shrink)

My strategy is to assume a "market libertarian" ideology for the purposes of this paper and then argue that employment offers directed toward people in desperate circumstances are predatory immoral offers. I develop comparisons between predatory behaviour that is widely held to be immoral (cases where people in power prey on the desperate, i.e., people who are desperately hungry, ignorant, secretive, etc.,) and the predatory behaviour of corporate agents who prey on desperate people for cheap labour. What all (...) of these cases have in common is that the predator takes advantage of the fact that the prey is not in a position to make a meaningful choice. When this argument by analogy is put in the context of the libertarian insistence that voluntary exchanges are at the foundation of everyone's freedom, it represents a devastating critique of neo-liberal consistency.

Bicchieri's topic is the modeling of interaction between decision makers in situations in which the outcome of the interaction depends on what the parties jointly do. Examples include chess, firms competing for business, politicians competing for votes, jury members deciding on a verdict, animals fighting over prey, bidders competing in auctions, threats and punishments in long-term relationships. Rationality assumptions are a basic ingredient of game theory, but though rational choice might be unproblematic in normative decision theory, it becomes (...) problematic in interactive contexts, where the outcome of one’s choice depends on the actions of other agents. Another basic ingredient is the idea of equilibrium play: roughly, an equilibrium is a combination of strategies, one for each player, such that each player’s strategy is a best reply to the other players’ choices. Thus it is individually rational for each agent to play her equilibrium strategy; but, notoriously, such individually rational play can lead to sub-optimal outcomes, as in the well-known prisoner’s dilemma. The relationship between rationality assumptions and equilibrium play is Bicchieri’s main focus. (shrink)

In this posthumously published paper Val Plumwood reflects on two personal encounters with death, being seized as prey by a crocodile and burying her son in a country cemetery with a flourishing botanic community. She challenges the exceptionalism which sets the human self apart from nature and which is reflected in the choice between two conceptions of death, one of continuity in the realm of spirit, the other a reductive materialist conception in which death marks the end of (...) the story of the self. Both perspectives structure out the basis of animal existence – that we are all food, and through death nourish others. She commends an animistic materialist approach, where life is seen as in circulation and where mortuary practices might affirm death as an opportunity of life for others in the ecological community.

During the lengthy and complex process of human evolution our ancestors had to adapt to extremely testing situations in which survival depended on making rapid choices that subjected muscles and the body as a whole to extreme tension. In order to seize a prey traveling at speeds that could reach 36 km per hour Homo sapiens had just thousandths of a second in which to anticipate the right moment and position himself before the prey arrived. He also had (...) to prepare the appropriate gesture, tensing his muscles and overcoming the resistance determined by body weight. While we are no longer faced with an environment that is anything so threatening, our brain continues to use these mechanisms day in day out to save time and energy, enabling us to avoid situations of danger, sense in advance the intentions of an interlocutor, and more besides. In this article we set out to show that our brain is not only a reactive mechanism, capable of reacting quickly to the stimuli that arrive from the external environment, but is above all a pro-active mechanism that allows us to make hypotheses, anticipate the consequences of actions, and formulate expectations: in short, to wrong foot an adversary.

Over the last 25 years, evolutionary game theory has grown with theoretical contributions from the disciplines of mathematics, economics, computer science and biology. It is now ripe for applications. In this book, Daniel Friedman---an economist trained in mathematics---and Barry Sinervo---a biologist trained in mathematics---offer the first unified account of evolutionary game theory aimed at applied researchers. They show how to use a single set of tools to build useful models for three different worlds: the natural world studied by biologists; the (...) social world studied by anthropologists, economists, political scientists and others; and the virtual world built by computer scientists and engineers. The first six chapters offer an accessible introduction to core concepts of evolutionary game theory. These include fitness, replicator dynamics, sexual dynamics, memes and genes, single and multiple population games, Nash equilibrium and evolutionarily stable states, noisy best response and other adaptive processes, the Price equation, and cellular automata. The material connects evolutionary game theory with classic population genetic models, and also with classical game theory. Notably, these chapters also show how to estimate payoff and choice parameters from the data. The last eight chapters present exemplary game theory applications. These include a new coevolutionary predator-prey learning model extending rock-paper-scissors; models that use human subject laboratory data to estimate learning dynamics; new approaches to plastic strategies and life cycle strategies, including estimates for male elephant seals; a comparison of machine learning techniques for preserving diversity to those seen in the natural world; analyses of congestion in traffic networks and the.

The question of how to frame agential preferences in economics finds one caught between Scylla and Charybdis. If preferences are framed in as minimal and deflationary a manner as revealed preference theory recommends, the theory falls prey to objections about its predictiveness and explanatory power. Alternatively, if too many cognitive and causal intricacies are incorporated into the preference concept, revealed preference models will violate pragmatic norms of model construction, surrendering model simplicity and generality. This paper charts a middle course, (...) arguing that the path to salvation lies through an understanding of revealed preference models as program explanations. (shrink)

Cunha and Caldieraro (2009) investigated whether sunk-cost effects, which are well documented in hypothetical situations involving monetary investments, also occur in choice situations with purely behavioral investments. Their results suggest that decision makers indeed fall prey to behavioral sunk-cost effects under certain circumstances. I have been unable to replicate their pattern of results in three separate investigations. In these studies, I attempted to recover the effect using two other behavioral effort manipulations in addition to the manipulation used by (...) Cunha and Caldieraro. This failure to replicate the pattern of results calls into question the robustness of the initial findings. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Adolf Meyer: Psychiatric AnarchistS. Nassir Ghaemi (bio)KeywordsMeyer, biopsychosocial model, Jaspers, pluralism, philosophy, psychiatryThey had weekly lunches in 1920s New York City: In one door stepped a stooped philosopher, with a mustache and a twinkle, perhaps ruminating on some recent Marxist theory; in the other door came the elegant Swiss physician, goateed and erudite. Every week, for a time, John Dewey (leader of American pragmatism) and Adolf Meyer (dean of (...) mid-twentieth century American psychiatry and long-time chair of the Johns Hopkins psychiatry department) lunched together and, somewhere in those conversations—one might imagine—the field of philosophy and psychiatry was born (Meyer 1948, 152).Yet pragmatism—as a proper school of philosophy—does not capture Meyer’s psychiatry. Rather, the core of his thinking, in my view, is to be found in a vague term that deserves analysis: eclecticism.EclecticismIt has been said that eclecticism is a vice in theory but a virtue in practice (Stone 1981), which highlights why so many are attracted to it. Deep down, practitioners just want to be free: They believe that their freedom of choice will tailor treatments best to patients and thus result in best outcomes. As a conceptual theory for psychiatry, eclecticism is a model that views any theory or method as potentially correct, but no theory or method as definitively incorrect. There is no way to avoid an “anything goes” practice with eclecticism: It is—to use a political analogy—an anarchism of mind.William James once remarked that the basis for all philosophies lies in the personalities of philosophers. So it was with Meyer’s eclecticism: congenial personally, he seemed congenitally incapable of disagreeing with any person. Any idea, even the most unusual, would receive a respectful hearing from Meyer. (Double brings out new, excellent documentary evidence of this extreme indecision in the drafts of Meyer’s unsent letters to the behaviorist John Watson.) Although quaint and commendable pedagogically, this excessive open mindedness left American psychiatry—so dependent on Meyer—prey to hard-headed biological radicals and psychoanalytic dogmatists. This is where his eclecticism failed us.Enabling Biological ExtremismMeyer played a key role in legitimizing extreme biological approaches. In addition to his interest in insulin coma (which Double mentions), Meyer enabled the popularization of colectomy and frontal [End Page 341] lobotomy. Psychiatric colectomy, developed by Henry Cotton, was based on the focal toxin theory of mental illness—the idea that mental illness was caused by toxins released by bacteria in the body, the specific locations of which where were the colon and rotted teeth. In one hundred case reports, with mostly short-term follow-up, published in his prominent text, The Defective Delinquent and Insane (Cotton 1921), Cotton laid out his case, which Meyer legitimized by writing a generous foreword. Meyer’s authority was powerful enough to render Cotton’s limited evidence base much more credible than it might otherwise have been. In the 1920s and 1930s, tens of thousands colectomies and full mouth teeth extractions were conducted in patients with mental illness. (Meyer himself sometimes recommended it).1The other biological extremist story is more famous. In a 1936 conference, with Meyer in attendance, the neurologist Walter Freeman presented, for the first time, cases of refractory schizophrenia treated with a new method: frontal lobotomy. Psychoanalyst attendees protested that Freeman was proposing nothing more than mutilation of the brain; yet Meyer intervened in favor of Free-man (“I am not antagonistic to this work, but find it very interesting” [El-Hai 2005]). Unfortunately, Freeman, like Cotton, was a dogmatist: Over time, he performed frontal lobotomy more and more extensively, not just as a treatment of last resort in the most ill schizophrenics (as in the first cases presented to Meyer), but later as a treatment of first resort for the mildest mood disorders. (By 1950 Freeman had personally conducted 2400 transorbital lobotomies, an “office procedure” that allowed him to lobotomize a patient in 15 minutes [El-Hai 2005]).2Lest my critique of Meyer in that era be seen as a Whiggish interpretation of history (the claim that we are so much smarter than those shrinks of the past; in fact I think...

In many coevolutionary systems members of one party select members of a second party based on quality differences existing among members of the latter (e.g., predators and prey, pollinators and flowers, etc.). We examined the fate of characters that increase (amplifiers) or decrease (attenuators) the perceived amplitude of differences in the quality upon which choice of the selecting party is based. We found that the evolution of such characters depends on (i) the relationship between the cost of the (...) character and the relative benefit it gives to the high quality individuals (if an amplifier) or low quality individuals (if an attenuator), and (ii) the frequency, among members of the selected party, of the quality sought by the selecting party.

Many recent studies of norm emergence employ the "prisoner's dilemma" (PD) paradigm, which focuses on the free-rider problem that can block the cooperation required for the emergence of social norms. This paper proposes an expansion of the PD paradigm to include a closely related game termed the "altruist's dilemma" (AD). Whereas egoistic behavior in the PD leads to collectively irrational outcomes, the opposite is the case in the AD: altruistic behavior (e.g., following the Golden Rule) leads to collectively irrational outcomes, (...) whereas egoistic behavior leads to Pareto-optimal outcomes. The analysis shows that PDs can be converted into ADs either by increasing cooperation costs or by diminishing marginal gains from cooperation; therefore ADs are as empirically abundant as PDs. In addition, the analysis shows that altruists are not the only type of actors who fall prey to the AD; egoists can fall into this trap as well if they possess a capacity for interpersonal control. Where group solidarity is defined analytically in terms of the extent of cooperation in both PDs and ADs, this paper presents a model based on rational choice to account for variations in solidarity. According to the proposed analysis, levels of group solidarity depend on the balance in the group between compliant control, which increases cooperation, and oppositional control, which reduces it. That balance, in turn, depends on the allocation of power within the group. (shrink)

ABSTRACTIn the face of widespread poverty, Peter Singer argues that the best response is giving money to charitable organizations that give aid to the poor. In response, much criticism has been leveled by cosmopolitan philosophers that philanthropy is unable to effectively combat poverty for many reasons: such funds fall prey to corrupt bureaucrats, the poor will waste the money, or become dependent upon donations rather than providing for themselves. In this paper, I argue that the work of the organization (...) GiveDirectly offers an approach that can overcome the criticisms leveled against philanthropy. GiveDirectly works by providing direct cash transfers to the poor; by adopting such a straightforward method, GiveDirectly provides practical benefits to the poor, and overcomes key philosophical critiques. The poor are empowered to make choices to meet their own needs, and do not become dependent upon donations. While GiveDirectly does not constitute the solution to the problem of global poverty, it does pro... (shrink)

In this paper, I examine the role played by the emotion of admiration in formulating moral judgments. First, I discuss whether and when admiration is a reliable source of moral knowledge, or, on the contrary, it misleads the subject, leaving her prey to forms of uncritical devotion to unworthy objects of admiration. To do so, I try to elucidate which underlying theory of emotions best allows one to characterize admiration as a reliable source of moral knowledge. Second, I introduce (...) the notion of transformative moral experience, understood as a subclass of transformative experiences, and I argue that it is precisely admiration that ensures the rationality of the choices made in such experiences. Finally, in light of this analysis, I show how admiration—together with the constellation of positive and negative emotions connected to the perception of moral exemplarity—acts as a central element for the maintenance of moral integrity. I defend, in particular, the idea that integrity should not be understood as mere coherence, nor as a static maintenance of the moral status quo, but as being firmly rooted in one’s own identity yet open to novelty and especially to the novelty represented by transformative moral experiences.

Seeing philosophy as conversation with a number of fruitful avenues of discourse, Rorty seems to be caught in limbo, unwilling to follow through or commit himself to any particular line of discourse for fear of closing himself off to alternative discourses. Choosing to adopt this particular attitude he still has made a choice: he has made a commitment to non-commitment, or as Ortega puts it, “decided not to decide.” Jose Ortega y Gasset, The Revolt of the Masses, trans. anonymously (...) (New York: W.W. Norton & Company, 1957), p. 48. Such a commitment or decision is in no way neutral, for it attempts to enforce, by moral requirement, Richard Rorty, Philosophy and the Mirror of Nature, p. 394. a new vocabulary which views philosophy as conversation between speakers, with a whole range of obligations and implications included. Thus the Rortian alternative, like the alternatives he criticizes, plays the role “of the cultural overseer who knows everyone's common ground — the Platonic philosopherking who knows what everybody else is really doing whether they know it or not, because he knows about the ultimate context ... within which they are doing it.” Ibid., pp. 317–318. In fact, Rorty even refers to “conversation as the ultimate context” Ibid., p. 389. In assuming to know everyone's common ground, that every-one is participating in the conversation of humankind whether they realize it or not, Rorty seems to fall prey to a similar “self-deceptive ... absurdity of thinking that the vocabulary [he uses] ... has some privileged attachment to reality which makes it more than just a further set of descriptions.” Ibid., p. 361.One implication of such a position is that despite its holder's claims that he or she will at least attempt to incorporate abnormal discourses of all sorts, the conversationalist will not be able to consider seriously a number of types of discourse. If the edifying, hermeneutical philosopher were really “willing to pick up the jargon of the interlocutor rather than translating it into his own terms,” Ibid., p. 318. it would often be necessary to drop the notion of conversation as being a fundamental practice or moral obligation. Rorty is obviously unwilling to really pick up the jargon of the epistemologist and the meta-physician he criticizes, or of Nietzsche and Stirner, for each of these does not have contained within them, at least as a primary consideration, the continuing of the conversation of humankind. Because he imposes his vocabulary and descriptions on them - they are merely speakers in a conversation - he will see them as merely threads in a larger social fabric, he will be translating their “jargon” into his own, and thus will never be able to take their position seriously, never be prepared to adopt their position as his own. Being possessed by the notion of continuing the conversation, he is closing himself off to traditional epistemological and metaphysical projects, as well as to the perspectives of thinkers like Stirner and Nietzsche, despite his claim to be open to all of them. He can only consider them as topics of conversation as long as he remains committed to conversation, and thus never consider them as live options, or consider them as alternative life-projects to be pursued on their own terms. In insisting on the moral obligation of philosophers to continue the conversation of the West, he is insisting on the moral obligation of philosophers not to whole-heartedly adopt any of the alternatives which would tend to close off this conversation. Therefore, instead of decrying “the very notion of having a view, while avoiding having a view about having views,” Ibid., p. 371. Rorty has a rather clear view about having views: one should not hold any view whole-heartedly except the view that philosophy should be conversation, and this conversation should be the way to decide among views; that is, the way to decide among all views except the view that conversation should be the way to decide, which for Rorty is not open to discussion, but is a moral obligation. All perspectives are encouraged in the conversation, but the conversational morality has already prescribed that these views should not be whole-heartedly adopted by responsible individuals. Requiring that philosophy be conversation, Rorty closes off numerous possible life-styles, and almost all traditional philosophical projects: he merely saves the appearances of these alternatives. Morally required to continue the conversation, philosophy becomes just talk. Along the same lines, when Rorty claims that the normal and abnormal discourses “do not compete, but rather help each other out,” Ibid., p. 346. he assumes that the epistemological and metaphysical discourses will be helped by various abnormal discourses, and assumes thinkers like Nietzsche and Stirner will be helped by being made to see the significance of societies which have fallen together and are united by civility. Yet, in doing this, Rorty is not attempting to understand - either sympathetically or intellectually - what it would mean to help these projects on their own terms, and as such is not trying to understand and assimilate these alternatives as he claims he is. Rather, he is holding each of these alternatives up to his own ideal of an “open conversation,” and judging what it would mean to “help out” these alternatives only according to his own particular standards. In continually translating what others are offering into his own particular frame of reference, he does not appreciate these philosophical alternatives for their worth as individual activities which can contribute to life and/or society, but values them only for what they can contribute to his larger project, the conversation of humankind. However, if these alternatives were taken seriously, then they would surely be seen to compete with his view which advocates social criteria for adjudicating disputes, thereby denying many of the fundamental aspects of the above-mentioned alternative philosophical under-takings. It should be seen that contrary to what Rorty suggests, edification also “provides only some, among many, ways of describing ourselves,” Ibid., p. 361. and is only one type of human project among many others. In suggesting that we shift our focus “from the relation between human beings and the objects of their inquiry to the relation between alternative standards of justification, and from there to the actual changes in these standards which make up intellectual history,” Ibid., pp. 389–390. Rorty neither breaks free from traditional concerns, nor brings the focus of attention onto our own lives. As Bernstein notes, “there is a sense in which Rorty himself is obsessed. It is almost as if he can't quite ‘let go’ and accept the force of his own critique. It is as if Rorty himself has been more deeply touched by what he is attacking than he realizes.... He himself is obsessed with the obsessions of philosophers.” R.J. Bernstein, “Philosophy in the Conversation of Mankind,” pp. 767, 775.As a result of this, Richard Eldridge correctly notes that Rorty is unable to realize that “[c]riticism matters just insofar as it enables us fruitfully to develop our lives and our practices out of the past.” Richard Eldridge, “Philosophy and the Achievement of Community: Rorty, Cavell and Criticism,” Metaphilosophy 14, No. 2 (1983), p. 124. As an alternative to the Rortian attitude, I invite the reader to entertain a perspective which is not primarily concerned with identifying oneself in accordance with, or in opposition to, particular traditions, but rather with assimilating and utilizing all previous philosophical labors in order to achieve the greatest appreciation of one's own personal possibilities, and the fullest expression of one's own powers.

Change, Choice and Inference develops logical theories that are necessary both for the understanding of adaptable human reasoning and for the design of intelligent systems. The book shows that reasoning processes - the drawing on inferences and changing one's beliefs - can be viewed as belonging to the realm of practical reason by embedding logical theories into the broader context of the theory of rational choice. The book unifies lively and significant strands of research in logic, philosophy, economics (...) and artificial intelligence. It elaborates on the relevant theories and provides a mathematically precise foundation for the thesis that large parts of theoretical reason can be subsumed under practical reason. (shrink)

While there are numerous doubts, controversies and lack of consensus on alternative definitions of human death, it is argued that it is more ethical to allow people to choose either cessation of cardio-respiratory function or loss of entire brain function as the definition of death based on their own views. This paper presents the law of organ transplantation in Japan, which allows people to decide whether brain death can be used to determine their death in agreement with their family. Arguably, (...) Japan could become a unique example of individual choice in the definition of death if the law is revised to allow individuals choose definition of death independently of their family. It suggests that such an approach is one of the reasonable policy options a country can adopt for legislation on issues related to the definition of death. (shrink)

Rational agents are supposed to maximize expected utility. But what are the options from which they choose? I outline some constraints on an adequate representation of an agent’s options. The options should, for example, contain no information of which the agent is unsure. But they should be sufficiently rich to distinguish all available acts from one another. These demands often come into conflict, so that there seems to be no adequate representation of the options at all. After reviewing existing proposals (...) for how to construe decision-theoretic options and finding them all wanting, I suggest that our model of rational agents should include a special domain of ‘virtual’ option propositions to serve as formal objects of deliberation and choice.

Our discussion of the commentaries begins, at the evolutionary level, with issues raised by our account of the evolution of morality in terms of partner-choice mutualism. We then turn to the cognitive level and the characterization and workings of fairness. In a final section, we discuss the degree to which our fairness-based approach to morality extends to norms that are commonly considered moral even though they are distinct from fairness.

Choices can be wise or foolish, and feelings can be apt or off the mark. So we judge, and it would be good to know what content these normative judgements carry. Gibbard offers an answer, and elaborates it. His theory explores what is at issue in narrowly moral questions, and in questions of rational thought and conduct in general.

Abstract“Sign stimuli” elicit specific patterns of behavior when an organism's motivation is appropriate. In the toad, visually released prey-catching involves orienting toward the prey, approaching, fixating, and snapping. For these action patterns to be selected and released, the prey must be recognized and localized in space. Toads discriminate prey from nonprey by certain spatiotemporal stimulus features. The stimulus-response relations are mediated by innate releasing mechanisms (RMs) with recognition properties partly modifiable by experience. Striato-pretecto-tectal connectivity determines the (...) RM's recognition and localization properties, whereas medialpallio-thalamo-tectal circuitry makes the system sensitive to changes in internal state and to prior history of exposure to stimuli. RMs encode the diverse stimulus conditions referring to the same prey object through different combinations of “specialized” tectal neurons, involving cells selectively tuned to prey features. The prey-selective neurons express the outcome of information processing in functional units consisting of interconnected cells. Excitatory and inhibitory interactions among feature-sensitive tectal and pretectal neurons specify the perceptual operations involved in distinguishing the prey from its background, selecting its features, and discriminating it from predators. Other connections indicate stimulus location. The results of these analyses are transmitted by specialized neurons projecting from the tectum to bulbar/spinal motor systems, providing a sensorimotor interface. Specific combinations of such projective neurons – mediating feature- and space-related messages – form “command releasing systems” that activate corresponding motor pattern generators for appropriate prey-catching action patterns.

The concepts of choice, negation, and infinity are considered jointly. The link is the quantity of information interpreted as the quantity of choices measured in units of elementary choice: a bit is an elementary choice between two equally probable alternatives. “Negation” supposes a choice between it and confirmation. Thus quantity of information can be also interpreted as quantity of negations. The disjunctive choice between confirmation and negation as to infinity can be chosen or not in (...) turn: This corresponds to set-theory or intuitionist approach to the foundation of mathematics and to Peano or Heyting arithmetic. Quantum mechanics can be reformulated in terms of information introducing the concept and quantity of quantum information. A qubit can be equivalently interpreted as that generalization of “bit” where the choice is among an infinite set or series of alternatives. The complex Hilbert space can be represented as both series of qubits and value of quantum information. The complex Hilbert space is that generalization of Peano arithmetic where any natural number is substituted by a qubit. “Negation”, “choice”, and “infinity” can be inherently linked to each other both in the foundation of mathematics and quantum mechanics by the meditation of “information” and “quantum information”.

Quantum frameworks for modeling competitive ecological systems and self-organizing structures have been investigated under multiple perspectives yielded by quantum mechanics. These comprise the description of the phase-space prey–predator competition dynamics in the framework of the Weyl–Wigner quantum mechanics. In this case, from the classical dynamics described by the Lotka–Volterra (LV) Hamiltonian, quantum states convoluted by statistical gaussian ensembles can be analytically evaluated. Quantum modifications on the patterns of equilibrium and stability of the prey–predator dynamics can then be identified. (...) These include quantum distortions over the equilibrium point drivers of the LV dynamics which are quantified through the Wigner current fluxes obtained from an onset Hamiltonian background. In addition, for gaussian ensembles highly localized around the equilibrium point, stability properties are shown to be affected by emergent topological quantum domains which, in some cases, could lead either to extinction and revival scenarios or to the perpetual coexistence of both prey and predator agents identified as quantum observables in microscopic systems. Conclusively, quantum and gaussian statistical driving parameters are shown to affect the stability criteria and the time evolution pattern for such microbiological-like communities. (shrink)

We make decisions every day. Yet we are sometimes perplexed by these decisions and the decisions of others. To complicate things further, we live in an age where there are more things to choose from than ever before – the Internet is transforming our choices and making us more accountable for them: what we choose is recorded, modelled and used to predict our future behaviour. So are we in a position to make better choices today than we were a decade (...) ago? Certainly there are some who believe so. Psychologists claim we are subject to hidden mental processes that lead us to one thing rather than another; economists offer predictions about what people will buy; and some philosophers claim that our choices echo our evolutionary past. Are these claims merited? Do they reflect the beginnings of a new science of choice? This book offers a critical overview of these and other claims, showing where they are justified and where they are exaggerated. It will be an essential reference for anyone interested in whether science can help us to understand both the ways people make choices in their everyday lives and how these may be changing. (shrink)
