As the cognitive revolution was slow to come to the study of animal behavior, the vast majority of what we know about primate cognition has been discovered in the last 30 years. Building on the recognition that the physical and social worlds of humans and their living primate relatives pose many of the same evolutionary challenges, programs of research have established that the most basic cognitive skills and mental representations that humans use to navigate those worlds are already possessed by (...) other primates. There may be differences between humans and other primates, however, in more complex cognitive skills, such as reasoning about relations, causality, time, and other minds. Of special importance, the human primate seems to possess a species-unique set of adaptations for “cultural intelligence,” which are broad reaching in their effects on human cognition. (shrink)
Porphyry's account of the nature of seeds can shed light on some less appreciated details of Neoplatonic psychology, in particular on the interaction between individual souls. The process of producing the seed and the conception of the seed offer a physical instantiation of procession and reversion, activities that are central to Neoplatonic metaphysics. In an act analogous to procession, the seed is produced by the father's nature, and as such it is ontologically inferior to the father's nature. (...) Thus, the seed does not strictly speaking contain a full-fledged vegetative soul. Rather, it acquires its vegetative soul only while it is being actualized by an actual vegetative soul. This actualization takes place primarily at conception, where the seed as it were reverts back and becomes obedient to the mother's nature, but continues through the period of gestation. In this way, Porphyry can account both for maternal resemblance and for ideoplasty. He uses the Stoic language of complete blending to describe the mother's relation to the seed and embryo, and this reveals that he thinks of individuals as having their own unique individual natures (as opposed to sharing in a single universal nature). In the course of developing this theory, Porphyry makes significant revisions to his philosophical predecessors' views in both embryology and botany. He revises Aristotle's verdict on the relative importance of the female in generation as well as Theophrastus' explanation of the biological mechanics of grafting. Although Plotinus nowhere addresses embryology in the same detail as Porphyry does, we can conclude from his remarks on seeds and plants that his own views were similar to those of his student.

A model is proposed for the population dynamics of an annual plant (Sesbania vesicaria) with a seed bank (i.e. in which a proportion of seeds remain dormant for at least one year). A simple linear matrix model is deduced from the life cycle graph. The dominant eigenvalue of the projection matrix is estimated from demographic parameters derived from field studies. The estimated values for population growth rate () indicates that the study population should be experiencing a rapid exponential increase, (...) but this was not the case in our population.The addition of density dependent effects on seedling survivorship and adult fecundity, effects for which field studies provide evidence, considerably improves our model. Depending on the demographic parameters, the model leads to stable equilibrium, oscillations, or chaos. Study of the behaviour of this model in the parameter space shows that the existence of a seed bank allows higher among-year variation of adult fecundity, without leaving the region of demographic stability. Field data obtained over 3 years confirm this prediction. (shrink)
This history of reproductive theories from Aristotle to the preformationists provides an excellent illustration of the ways in which the gender/science system informs the process of scientific investigation. In this essay I examine the effects of the bias of woman's inferiority upon theories of human reproduction. I argue that the adherence to a belief in the inferiority of the female creative principle biased scientific perception of the nature of woman's role in human generation.

Each plant can be recognized by its general shape. Nevertheless, this physiognomy is the result of a very precise structure that expresses the existence of a strong organization. The architecture of a plant depends on the nature and relative arrangement of each of its parts; it is at any given time the result of an equilibrium between endogenous growth processes and the constraints exerted by the environment. Architectural studies have been carried out for some twenty years and have led to (...) the definition of several concepts that provide a powerful tool for studying plant form. The results obtained in this field show that the architecture of a plant can be summarized by a small number of elementary structures: internode, growth unit, axis, architectural model,... In the course of ontogenesis, these structures are repeated and reveal several levels of organization that seem to be only different stages of a common process of growth and transformation. (shrink)
In an effort to restrict seed piracy in the global agricultural market, Monsanto intends to implement some form of genetic use restriction technology (GURT). Regarding such intentions, many activist groups adamantly contend that Monsanto will be acting immorally if GURTs, specifically Terminator Technology (TT), are implemented in the global agricultural market. They argue that the potential implementation of TT is immoral because it threatens to infringe upon the rights of resource-poor farmers (mainly in developing countries) by denying them the (...) ability to save the seed derived from their harvests. While there may be ways that the implementation of TT can be construed as wrong, I narrowly argue that Monsanto will not be wrongfully infringing upon the basic rights of resource-poor farmers if it actually implements TT. Moreover, as long as Monsanto takes the appropriate measures to minimize the possible negative effects that TT may have on resource-poor farmers, and allows these farmers to make an autonomous choice to use seed that contains this technology, Monsanto’s possible implementation of TT cannot be accurately considered to instantiate an immoral violation of basic rights.

How do the ways we argue represent a practical philosophy or a way of life? Are concepts of character and ethos pertinent to our understanding of academic debate? In this book, Amanda Anderson analyzes arguments in literary, cultural, and political theory, with special attention to the ways in which theorists understand ideals of critical distance, forms of subjective experience, and the determinants of belief and practice. Drawing on the resources of the liberal and rationalist tradition, Anderson interrogates the limits (...) of identity politics and poststructuralism while holding to the importance of theory as a form of life. Considering high-profile trends as well as less noted patterns of argument, The Way We Argue Now addresses work in feminism, new historicism, queer theory, postcolonialism, cosmopolitanism, pragmatism, and proceduralism. The essays brought together here--lucid, precise, rigorously argued--combine pointed critique with an appreciative assessment of the productive internal contests and creative developments across these influential bodies of thought. Ultimately, The Way We Argue Now promotes a revitalized culture of argument through a richer understanding of the ways critical reason is practiced at the individual, collective, and institutional levels. Bringing to the fore the complexities of academic debate while shifting the terms by which we assess the continued influence of theory, it will appeal to readers interested in political theory, literary studies, cultural studies, gender studies, and the place of academic culture in society and politics.

Applying the seed concept to Prikry tree forcing P μ , I investigate how well P μ preserves the maximality property of ordinary Prikry forcing and prove that P μ Prikry sequences are maximal exactly when μ admits no non-canonical seeds via a finite iteration. In particular, I conclude that if μ is a strongly normal supercompactness measure, then P μ Prikry sequences are maximal, thereby proving, for a large class of measures, a conjecture of W. Hugh Woodin's.
The notions of selflessness ( an tmaka ) and karman are two key concepts in Buddhist philosophy. The question how karman functions with respect to the rebirth of a worldling who is, actually, devoid of a self, was a major philosophical issue in early Buddhist doctrine.

McKenzie Seeds is a crown corporation owned by the people of Manitoba. In 1983, the company was rocked by a scandal involving its senior management. During the course of the controversy, George F. MacDowell resigned as chairman of the McKenzie Seeds board of directors. He subsequently wrote a pamphlet which attempted to provide a context for understanding events at McKenzie Seeds. This paper provides a brief history of the company and a discussion of MacDowell's pamphlet. A postscript provides information on (...) some recent developments, which suggests that the issues raised by the scandal and identified in the pamphlet remain unresolved. (shrink)
Growing up, I was a mathematics and science geek. I read everything I could in these areas. Every now and then, something would point in a philosophical direction. Perhaps my most important influence was reading Hofstadter’s Gödel, Escher, Bach as a teenager. I read it initially for the mathematical parts, but it planted a seed for thinking about the mind. Later, Hofstadter and Dennett’s The Mind’s I got me thinking more about the mind–body problem in particular.
This paper introduces a new, expanded range of relevant cognitive psychological research on collaborative recall and social memory to the philosophical debate on extended and distributed cognition. We start by examining the case for extended cognition based on the complementarity of inner and outer resources, by which neural, bodily, social, and environmental resources with disparate but complementary properties are integrated into hybrid cognitive systems, transforming or augmenting the nature of remembering or decision-making. Adams and Aizawa, noting this distinctive complementarity argument, (...) say that they agree with it completely: but they describe it as “a non-revolutionary approach” which leaves “the cognitive psychology of memory as the study of processes that take place, essentially without exception, within nervous systems.” In response, we carve out, on distinct conceptual and empirical grounds, a rich middle ground between internalist forms of cognitivism and radical anti-cognitivism. Drawing both on extended cognition literature and on Sterelny’s account of the “scaffolded mind” (this issue), we develop a multidimensional framework for understanding varying relations between agents and external resources, both technological and social. On this basis we argue that, independent of any more “revolutionary” metaphysical claims about the partial constitution of cognitive processes by external resources, a thesis of scaffolded or distributed cognition can substantially influence or transform explanatory practice in cognitive science. Critics also cite various empirical results as evidence against the idea that remembering can extend beyond skull and skin. We respond with a more principled, representative survey of the scientific psychology of memory, focussing in particular on robust recent empirical traditions for the study of collaborative recall and transactive social memory. We describe our own empirical research on socially distributed remembering, aimed at identifying conditions for mnemonic emergence in collaborative groups. Philosophical debates about extended, embedded, and distributed cognition can thus make richer, mutually beneficial contact with independently motivated research programs in the cognitive psychology of memory.

This paper assesses the potential of organisational culture as a means for improving ethics in organisations. Organisational culture is recognised as one determinant of how people behave, more or less ethically, in organisations. It is also incresingly understood as an attribute that management can and should influence to improve organisational performance. When things go wrong in organisations, managers look to the culture as both the source of problems and the basis for solutions. Two models of organisational culture and ethical behaviour (...) are evaluated. They rest on different understandings of organisational culture and the processes by which ethics are enhanced. Firstly, the prevailing approach holds that creating a unitary cohesive culture around core moral values is the solution to enhancing ethical behaviour. Both the feasibility and desirability of this approach, in terms of ethical outcomes, is questioned. The second model queries the existence of organisational culture at all, arguing that organisations are nothing more than shifting coalitions of subcultures. In this second model, the very porousness of the subcultures provides a catalyst for the scrutiny and critique of norms and practices. Such diversity and debate is construed as potentially a better safeguard for ethical behaviour than the uniformity promised by the unitary, strong culture model. (shrink)
Writers, philosophers, and theologians have oft made the comparison between being a mature human being and a masterpiece work of art or design. Employing the analogy between the creation of artistic value and the creation of full-fledged human value, this paper stakes out a middle ground between pro-choice and pro-life by considering a more general account of value and the relationship between being a potential X and a mature implementation of X's potential. I argue that the value of a potential (...) X is a function of a number of factors, most importantly, what I call the "accessibility relation" between a potential X and a full-fledged instantiation of this potential. The value is as much intrinsic to the “seed” as to some future implementation of the seed’s potential. This approach inclines even a secular humanist to reasonably confer a significant degree of moral value to a human conceptus, and even more to an early term fetus. (shrink)
The article analyzes the neural and functional grounding of language skills as well as their emergence in hominid evolution, hypothesizing stages leading from abilities known to exist in monkeys and apes and presumed to exist in our hominid ancestors right through to modern spoken and signed languages. The starting point is the observation that both premotor area F5 in monkeys and Broca's area in humans contain a “mirror system” active for both execution and observation of manual actions, and that F5 (...) and Broca's area are homologous brain regions. This grounded the mirror system hypothesis of Rizzolatti and Arbib (1998) which offers the mirror system for grasping as a key neural “missing link” between the abilities of our nonhuman ancestors of 20 million years ago and modern human language, with manual gestures rather than a system for vocal communication providing the initial seed for this evolutionary process. The present article, however, goes “beyond the mirror” to offer hypotheses on evolutionary changes within and outside the mirror systems which may have occurred to equip Homo sapiens with a language-ready brain. Crucial to the early stages of this progression is the mirror system for grasping and its extension to permit imitation. Imitation is seen as evolving via a so-called simple system such as that found in chimpanzees (which allows imitation of complex “object-oriented” sequences but only as the result of extensive practice) to a so-called complex system found in humans (which allows rapid imitation even of complex sequences, under appropriate conditions) which supports pantomime. This is hypothesized to have provided the substrate for the development of protosign, a combinatorially open repertoire of manual gestures, which then provides the scaffolding for the emergence of protospeech (which thus owes little to nonhuman vocalizations), with protosign and protospeech then developing in an expanding spiral. It is argued that these stages involve biological evolution of both brain and body. By contrast, it is argued that the progression from protosign and protospeech to languages with full-blown syntax and compositional semantics was a historical phenomenon in the development of Homo sapiens, involving few if any further biological changes. Key Words: gestures; hominids; language evolution; mirror system; neurolinguistics; primates; protolanguage; sign language; speech; vocalization. (shrink)
Recursion or self-reference is a key feature of contemporary research and writing in semiotics. The paper begins by focusing on the role of recursion in poststructuralism. It is suggested that much of what passes for recursion in this field is in fact not recursive all the way down. After the paradoxical meaning of radical recursion is adumbrated, topology is employed to provide some examples. The properties of the Moebius strip prove helpful in bringing out the dialectical nature of radical recursion. (...) The Moebius is employed to explore the recursive interplay of terms that are classically regarded as binary opposites: identity and difference, object and subject, continuity and discontinuity, etc. To realize radical recursion in an even more concrete manner, a higher-dimensional counterpart of the Moebius strip is utilized, namely, the Klein bottle. The presentation concludes by enlisting phenomenological philosopher Maurice Merleau-Ponty’s concept of depth to interpret the Klein bottle’s extra dimension. (shrink)
The Christian tradition has always taken a generally negative view of abortion, but the moral basis and perceived implications of this negative view have varied greatly. In the early Church abortion and contraception were often seen as broadly equivalent, both involving interference with the natural reproductive process (and an association with sexual immorality which even led some to see contraception as the more sinful of the two). But the tendency to conflate abortion with contraception, and even on similar grounds with (...) male masturbation, declined in the face of the biological discovery of the mother's role as more than just an incubator for the male "seed" - with the recognition of conception as a distinct and crucial event, abortion became generally seen as morally far more serious than contraception, potentially involving threat to an innocent life and therefore, arguably, equivalent to homicide. When seen as homicide, abortion has naturally been subject to an almost total prohibition, the only generally agreed exception being where it is necessary to save the mother's life. Within the Roman Catholic communion, moreover, even this exception has tended to be countenanced only when sanctioned by the doctrine of double effect - where the abortion is not directly intended, but is only a foreseen but unintended consequence of a surgical intervention whose primary intention is to save the mother's life (e.g. the removal of a cancerous uterus or of a fallopian tube containing an ectopic pregnancy).

In the future, human destiny may depend on our ethics. In particular, biotechnology and expansion in space can transform life, raising profound questions. Guidance may be found in Life-centered ethics, as biotic ethics that value the basic patterns of organic gene/protein life, and as panbiotic ethics that always seek to expand life. These life-centered principles can be based on scientific insights into the unique place of life in nature, and the biological unity of all life. Belonging to life then implies (...) a human purpose: to safeguard and propagate life. Expansion in space will advance this purpose but will also raise basic questions. Should we expand all life or only intelligent life? Should we aim to create populations of trillions? Should we seed other solar systems? How far can we change but still preserve the human species, and life itself? The future of all life may be in our hands, and it can depend on our guiding ethics whether life will fulfil its full potentials. Given such profound powers, life-centered ethics can best secure future generations. Our descendants may then understand nature more deeply, and seek to extend life indefinitely. In that future, our human existence can find a cosmic purpose. (shrink)
Noel and Amanda Sharkey have written an insightful paper on the ethical issues concerned with the development of childcare robots for infants and toddlers, discussing the possible consequences for the psychological and emotional development and wellbeing of children. The ethical issues involving the use of robots as toys, interaction partners or possible caretakers of children are discussed reviewing a wide literature on the pathology and causes of attachment disorders. The potential risks emerging from the analysis lead the authors to (...) promote a multidisciplinary debate on the current legislation to deal with future robot childcare. As a general first consideration, the questions arising from the paper are extremely timely since current robot technology is surprisingly close to achieving autonomous bonding and sustained socialization with human toddlers. The evolution of robot technology has been so speedy in the last few years that even if a discipline like Human-machine Interaction has only recently welcomed human-robot interaction within its disciplinary scope, a variety of social robots have started to populate our life and daily activities. In the past five years human-robot interaction has received a significant and growing interest leading to the development of the so-called robots companions, a term that emphasizes a constant interaction and co-operation between human beings and robotic machines. While Noel and Amanda Sharkey in their paper take a critical stance on the consequences of the use of robots as companions or caretakers, others researchers seem more keen to highlight the potential of caregiver robots in particular in educational settings. In this commentary I’ll try to offer my personal viewpoint on the consequences of using robot companions or caretakers of children on learning and education, and the effects of technologies on cognitive skills development, a controversial area of research where different findings show how little is known.

In this article I argue that despite the claims of some, all whites in racialized societies "have race." But because of the current context of race in our society, I argue that scholars of "whiteness" face several difficult theoretical and methodological challenges. First is the problem of how to avoid essentializing race when talking about whites as a social collective. That is, scholars must contend with the challenge of how to write about what is shared by those racialized as white (...) without implying that their experiences of racialization all will be the same. Second, within the current context of color-blind racial discourse, researchers must confront the reality that some whites claim not to experience their whiteness at all. Third, studies of whiteness must not be conducted in a vacuum: racial discourse or "culture" cannot be separated from material realities. Only by attending to and by recognizing these challenges will empirical research on whiteness be able to push the boundaries of our understandings about the role of whites as racial actors and thereby also contribute to our understanding of how race works more generally.

Childcare robots are being manufactured and developed with the long term aim of creating surrogate carers. While total childcare is not yet being promoted, there are indications that it is 'on the cards'. We examine recent research and developments in childcare robots and speculate on progress over the coming years by extrapolating from other ongoing robotics work. Our main aim is to raise ethical questions about the part or full-time replacement of primary carers. The questions are about human rights, privacy, (...) robot use of restraint, deception of children and accountability. But the most pressing ethical issues throughout the paper concern the consequences for the psychological and emotional wellbeing of children. We set these in the context of the child development literature on the pathology and causes of attachment disorders. We then consider the adequacy of current legislation and international ethical guidelines on the protection of children from the overuse of robot care. (shrink)
Generic statements (e.g., “Birds lay eggs”) express generalizations about categories. In this paper, we hypothesized that there is a paradoxical asymmetry at the core of generic meaning, such that these sentences have extremely strong implications but require little evidence to be judged true. Four experiments confirmed the hypothesized asymmetry: Participants interpreted novel generics such as “Lorches have purple feathers” as referring to nearly all lorches, but they judged the same novel generics to be true given a wide range of prevalence (...) levels (e.g., even when only 10% or 30% of lorches had purple feathers). A second hypothesis, also confirmed by the results, was that novel generic sentences about dangerous or distinctive properties would be more acceptable than generic sentences that were similar but did not have these connotations. In addition to clarifying important aspects of generics’ meaning, these findings are applicable to a range of real-world processes such as stereotyping and political discourse. (shrink)
This essay revisits the question of Sartre's method with particular emphasis on the posthumously published Notebooks for an Ethics , Critique of Dialectical Reason ( Volume II ), and “Morale et histoire.” I argue that Sartre's method—an ever-evolving though never seamless blend of phenomenological description, dialectical analysis, and logical inference—is at once the seed and fruit of his mature ontology of praxis. Free organic praxis, what Sartre more than once calls “the human act,” is neither closed nor integral, but (...) is rather intrinsically open-ended and integrative. Thus a philosophical method that seeks at once to illuminate human experience and human history must itself be both a reflection and inflection of the essential openness and integrativity of praxis itself. In the conclusion, I argue that the openness and integrativity of Sartre's method are its core strengths and the sources of its continued philosophical worth. (shrink)
When Charles Darwin (1859, 482) wrote in the Origin of Species that he looked to the “young and rising naturalists” to heed the message of his book, he likely had in mind individuals like Ernst Haeckel (1834-1919), who responded warmly to the invitation (Haeckel, 1862, 1: 231-32n). Haeckel became part of the vanguard of young scientists who plowed through the yielding turf to plant the seed of Darwinism deep into the intellectual soil of Germany. As Haeckel would later observe, (...) the seed flourished in extremely favorable ground. The German mind, he would write (1868), was predisposed to adopt the new theory. The great philosopher Immanuel Kant (1724- 1804), for instance, was on the verge of accepting a transmutational view in his Third Critique (1790; 1957, 538-39), though he stepped gingerly back from the temptation. Johann Wolfgang von Goethe (1749-1832), about the same time, dallied with transmutational ideas, at least Haeckel would convince Darwin that the Englishman had an illustrious predecessor. Jean-Baptiste de Lamarck’s (1744-1829) conceptions had taken hold among several major German thinkers in the first few decades of the nineteenth century in a way they had not in England and France. Among those ready to declare themselves for the new dispensation was Rudolf Virchow (1821-1902), Haeckel’s teacher at Würzburg—though, this very political scientist would prove Haeckel’s nemesis later in the century. So Haeckel’s estimate of the ripeness of German thought was not off the mark. Darwinism took hold in the newly unified land, though not without some struggle; but at last it became the dominant view in the biological sciences. But with its success did it foster the malign racist ideology that transfixed Adolf Hitler (1889-1945)? (shrink)
Clinical delusions are difficult to investigate in the laboratory because they co-occur with other symptoms and with intellectual impairment. Partly for these reasons, researchers have recently begun to use hypnosis with neurologically intact people in order to model clinical delusions. In this paper we describe striking analogies between the behavior of patients with a clinical delusion of mirrored self misidentification, and the behavior of highly hypnotizable subjects who receive a hypnotic suggestion to see a stranger when they look in the (...) mirror. Based on these analogies, we argue that the use of hypnosis is a reliable method to investigate the surface features of clinical delusions. But to what extent can hypnosis successfully recreate delusions? Can it also contribute to a better understanding of delusion formation? Although clinical delusions and hypnotically induced beliefs are different in etiology, some analogies can be identified in the underlying processes that characterise them, based on the two-factor theory of delusion formation.

To the extent they have adopted a cafeteria-style approach to Nietzsche's trademark conceptions, kneading and molding his words into chimerical constructs, postmodernist philosophers inevitably remind us of Zarathustra's description of 'scholars': 'They work like mills and like stamps: throw down your seed-corn to them and they will know how to grind it small and reduce it to white dust' ( TSZ , II, 16). If so, how much significance might we attribute to any postmodernist's 'findings' of any textual nuances (...) in Nietzsche's relativism and stylistic multiplicity - nuances which at one moment appear intimately to apply and at the next to be hopelessly impertinent to whatever point that postmodernist is straining to make? The answer ought to be clear: By maintaining that there exist no intrinsically privileged vantage platforms vis-à-vis any text whatever, postmodernists in effect subvert their own analyses, and thus leave every work they consider unaffected. In that sense, we should be on target to advance that postmodernists are, au fond , engaged in writing for the sake of writing; indeed, what delivers them from sheer irrelevance is nothing but their clamorous advocacy of universal egalitarianism. This, however, necessarily reaffirms the nature and hankerings of the 'race' of the last man, and thus perverts the teleological direction of Nietzsche's aesthetics. Those who regard postmodernism as a regressive movement must therefore attempt to set the record straight by arguing that Nietzsche's relativism is, in fact, only a means to the eventual (phenomenal) realization of his Übermensch idea.

Philosophy of science emerged as a distinctive part of philosophy in the twentieth century. It set its own agenda, the systematic study of the metaphysical and epistemological foundations of science, and acquired its own professional structure, departments and journals. Its defining moment was the meeting (and the clash) of two courses of events: the breakdown of the Kantian philosophical tradition and the crisis in the sciences and mathematics in the beginning of the century. The emergence of the new Frege-Russell logic, (...) the arithmetisation of geometry and the collapse of classical mechanics called into question the neat Kantian scheme of synthetic a priori principles. But the thought that some a priori (framework) principles should be in place in order for science to be possible had still had a strong grip on the thinkers of the European continent. A heated intellectual debate started concerning the status of these a priori principles. The view that dominated the scene after the dust had settled was that the required framework principles were conventions. The seed of this thought was found in Poincaré’s writings, but in the hands of the Logical Positivists, it was fertilised with Frege’s conception of analyticity and Hilbert’s conception of implicit definitions. The consolidation of modern physics lent credence to the view that a priori principles can be revised; hence, a new conception of relativised a priori emerged. The linguistic turn in philosophy re-oriented the subject-matter of philosophical thinking about science to the language of science. Formal-logical methods and conceptual analysis were taken to be the privileged philosophical tools. Not only, it was thought, do they clarify and perhaps solve (or dissolve) traditional philosophical problems; they also make philosophy rigorous and set it apart from empirical science. In the 1930s, philosophy of science became the logic of science; it became synonymous to anti-psychologism, anti-historicism and anti-naturalism.. (shrink)

Technological advancement has an ambivalent character concerning the impact on biodiversity. It accounts for major detrimental environmental impacts and aggravates threads to biodiversity. On the other hand, from an application perspective of environmental science, there are technical advancements, which increase the potential of analysis, detection and monitoring of environmental changes and open a wider spectrum of sustainable use strategies.The concept of biodiversity emerged in the last two decades as a political issue to protect the structural and functional basis of (...) earthbound life. In this respect, it represents a great challenge for science, in particular for ecology, which is the scientific discipline mainly involved in contributing to understand biodiversity issues.In this paper, we state a strong necessity for ecologists to work in close connection with other disciplines and within their own discipline across the different organisation levels. Each level has some specific properties to which ecological terminology has been adapted, and joint views are necessary to understand complex networks. In this context, ecological theory provides the background to analyse biological complexity and the relationship of structure and dynamics on different integration levels and provides the interface to mediate social and political issues.Important features of new technologies for advances in ecological theory refer to (1) an increase in information processing capacities, (2) more efficient automatic data acquisition and device operation, and (3) an increase in resolution (grain and extent).One crucial consideration we analyse is the trend that a quantitative development in one particular discipline may open a new potential for qualitative advancement in other disciplines when the quantitative advancement is applied in a new disciplinary context.We illustrate these qualitative developments that are based on technological advancements and which helped to advance ecological theory qualitatively with two examples: (1) The underlying mechanisms causing regularly oscillating rodent populations are subject to a decade long discussion in ecology. Using the possibilities of modern information processing, it is possible to represent the discussed hypotheses in an integrative object oriented model and analyse how the underlying causal net works. (2) The second example originates from biosafety research dealing with the environmental impact of genetically modified organisms (GMO). The project GenEERA develops a complex up-scaling procedure from below field-level information to the landscape scale in order to investigate spread and persistence of GM oil seed rape (Brassica napus) under different scenarios. The approach gives an example, how ecological modelling can be used to combine different information levels to derive conclusions on a higher spatial scale.In an overall conclusion we relate the described approaches to a wider system analytical context in which we interpret theory developments and biodiversity issues with a system theoretical description of growth processes. We obtain the view that in self-organising systems there is a tendency for autonomous development which tends to be dominating far away from capacity limitations. However, while approaching capacity limitations, a tendency towards closer coupling of internal and external cause-effect networks emerges. We also find that the relation of biodiversity, ecosystem services, and social dynamics can be interpreted in this framework. In this context, the demand for closer interdisciplinary cooperation to solve existing problems appears as an indication of emerging capacity limitations (or the reaching of saturation levels) both, in the theoretical as well as in the (bio-) physical domain.

I am one of your possible futures. One day, I hope, you will become me. Should fortune grant this wish, then I am not just a possible future of yours, but your actual future: a coming phase of you, like the full moon that follows a waxing crescent, or like the flower that follows a seed. I am writing to tell you about my life – how marvelous it is – that you may choose it for yourself.
We can learn about human ethics from machines. We discuss the design of a working machine for making ethical decisions, the N-Reasons platform, applied to the ethics of robots. This N-Reasons platform builds on web based surveys and experiments, to enable participants to make better ethical decisions. Their decisions are better than our existing surveys in three ways. First, they are social decisions supported by reasons. Second, these results are based on weaker premises, as no exogenous expertise (aside from that (...) provided by the participants) is needed to seed the survey. Third, N-Reasons is designed to support experiments so we can learn how to improve the platform. We sketch experimental results that show the platform is a success as well as pointing to ways it can be improved. (shrink)
Experimental memory research has traditionally focused on the individual, and viewed social influence as a source of error or inhibition. However, in everyday life, remembering is often a social activity, and theories from philosophy and psychology predict benefits of shared remembering. In a series of studies, both experimental and more qualitative, we attempted to bridge this gap by examining the effects of collaboration on memory in a variety of situations and in a variety of groups. We discuss our results in (...) terms of a functional view of collaborative remembering, and consider when and in what ways remembering with others might help or hinder memory. (shrink)
The purpose of this article is to show how moral imagination can be cultivated through meditation. Moral imagination was conceived as a three-stage process of ethical development. The first stage is reproductive imagination, that involves attaining awareness of the contextual factors that affect perception of a moral problem. The second stage, productive imagination, consists of reframing the problem from different perspectives. The third stage, creative imagination, entails developing morally acceptable alternatives to solve the ethical problem. This article contends that moral (...) imagination can be cultivated through three kinds of meditation: non-discursive, semidiscursive, and discursive meditation. Part one shows how the seed of reproductive moral imagination is planted during sessions of nondiscursive meditation. Productive moral imagination, as will be shown in part two, is nurtured through semidiscursive meditation. Part three will demonstrate the flowering of creative moral imagination through discursive meditation. Reflection and small group discussion on each form of meditation will help to show business people how to cultivate moral imagination. (shrink)
From seed to table, the food chain is gendered. When seeds and food are in women’s hands, seeds reproduce and multiply freely, food is shared freely and respected. However, women’s seed and food economy has been discounted as “productive work.” Women’s seed and food knowledge has been discounted as knowledge. Globalization has led to the transfer of seed and food from women’s hands to corporate hands. Seed is now patented and genetically engineered. It is treated (...) as the creation and “property” of corporations like Monsanto. Renewable seed becomes nonrenewable. Sharing and saving seed becomes a crime. Diversity, nourished by centuries of women’s breeding, disappears, and with it the culture and natural evolution that is embodied in the diversity is lost forever. Food, too, is transformed in corporate hands. It is no longer our nourishment; it becomes a commodity. And as a commodity it can be manipulated and monopolized. If food grain makes more money as cattle feed than it does as food for human consumption, it becomes cattle feed. If food grain converted to biofuel to run automobiles is more profitable, it becomes ethanol and biodiesel. (shrink)
The Psychological Study of Social Memory Phenomena Very often our memories of the past are of experiences or events we shared with others. And “in many circumstances in society, remembering is a social event” (Roediger, Bergman, & Meade, 2000, p.129): parents and children reminisce about significant family events, friends discuss a movie they just saw together, students study for exams with their roommates, colleagues remind one another of information relevant to an important group decision, and complete strangers discuss a crime (...) they happened to witness together. Psychology is at the heart of recent interdisciplinary efforts to understand the relationships between an individual remembering alone, an individual remembering in a group, and the group itself remembering.

monsters, virtual legends such as 2001’s HAL or Demon Seed’s Proteus are actually scary because of their mind. Without lingering on the philosophical debates on whether a certain type of mind can exist independent of its specific embodiment or whether any creature can understand a consciousness that is not like his own (recall Lem’s Solaris), the thing that makes HAL and Proteus so human is not so much their ability to think as their possessing something resembling human consciousness. The (...) point is that, whereas consciousness may or may not be required for an artificial agent to think, it is an essential element in creating anything resembling a human-like thinker that would pass the Turing Test.

In this paper I consider one aspect of how student writing is supported in the university. I focus on the use of the 'writing frame', questioning its status as a vehicle for facilitating student voice, and in the process questioning how that notion is itself understood. I illustrate this by using examples from the story of the 1944 Hollywood film Gaslight and show that apparent means of facilitating voice can actually contribute to a state of voicelessness. The paper considers what (...) recovery of voice entails and the role of the 'voice coach' both in the film, and in the classroom. Drawing on the work of Stanley Cavell, his readings of Gaslight and of the American writers Thoreau and Emerson, I explore the themes of crisis and transformation in relation to the self and society. Thoreau's notion of the father tongue and his metaphor of the axe are considered in relation to the concept of voice and are shown to be suggestive of a mature relationship to language and of an Emersonian self-reliance that is denied by the mere technical skill and mastery learning of some current approaches to academic writing.

I argue that Stephen Darwall's account of second-personal respect should be of special interest to feminists because it opens up space for the development of certain feminist resources. Specifically, Darwall's account leaves room for an experiential aspect of respect, and I suggest that abilities related to this aspect may vary along with social position. I then point out a potential parallel between the feminist critique of epistemology and a budding feminist critique of moral philosophy (specifically relating to respect).
Pairing Thus Spoke Zarathustra with On the Genealogy of Morality foregrounds tensions between artistic creation and critical interpretation in Nietzsche's work. From The Birth of Tragedy to his genesis of the concept, Will to Power, Nietzsche describes the real, or ?what is,? in terms of a creative, form-giving force. We might therefore read Zarathustra?a linguistically experimental, richly allegorical, self-reflexive, modernist prose poem?as the pre-eminent, artistic mode of philosophical expression, at least for Nietzsche. But Zarathustra is followed by a sober Abhandlung (...) (treatise), which professes a scientific goal of ?getting to the bottom of things? by uncovering the contingency, origin, and fabricated nature of supposedly eternal, ?given? values. These instantiations of Nietzsche-the-artist and Nietzsche-the-critic suggest art's ?double? or contradictory nature?a nature that accents its kinship with philosophy. Zarathustra and the Genealogy, read together, hint that the destruction of idols?or de-constructive, critical interpretation more generally?is not just supplemental to, but a necessary moment within the aesthetic itself.

In the Nicomachean ethics, Aristotle sets down a scattered and fractional account of the development of moral virtue within young people. Philosopher Martha Nussbaum defends Aristotle's neglect of a systematic account of moral development and argues that more complex expressions of character?building, such as learning to expose oneself to proper desires, feelings, pleasures and pains, are better illustrated through drama or literature than through philosophy. In this vein, the author draws upon literary thinkers J.B. Kerfoot, Sven Birkerts and Wayne C. (...) Booth, as well as the imaginative Harry Potter series by J. K. Rowling, to illustrate more concretely Aristotle's process of moral development. The author concludes with a proviso about the vulnerability of the connected process of reading and moral development in the current consumer culture. (shrink)
Mining companies in Australia are increasingly required to interact with Indigenous groups as stakeholders following Native Title legislation in the early 1990s. A study of five mining companies in Australia reveals that they now undertake a range of programs involving Indigenous communities, to assist with access to land, and to enhance their public profile. However, most of these initiatives emanate from carefully quarantined sections of mining companies. Drawing upon cross-cultural and diversity research in particular, this paper contends that only initiatives (...) that strive towards power sharing with Indigenous groups and strategies for broadening the organizational interface with Indigenous groups, will contribute to more ethical practices in mining and other companies.

This paper explores three current notions of literacy, which underpin the theorisation and practice of teaching and learning for both children and adults in England. In so doing, it raises certain problems inherent in these approaches to literacy and literacy education and shows how Stanley Cavell's notions of reading, and especially his reading of Thoreau's Walden , help to construct a notion not of literacy, but of being literate. The paper takes four themes central to Cavell's work in his The (...) senses of Walden : awakening; estrangement and familiarity; conviction; and the obligation to read, and argues that these ideas offer an approach to language, and an understanding of reading in particular, that is different from current iterations of literacy. Such ideas, though alien to current - mainly empirical - work within literacy studies, have a resonance for literacy research and education today. (shrink)
Whatever the original intent, the introduction of the term 'thought experiment' has proved to be one of the great public relations coups of science writing, For generations of readers of scientific literature, the term has planted the seed of hope that the fragment of text they have just read is more than mundane. Because it was a thought experiment, does it not tap into that infallible font of all wisdom in empiricist science, the experiment? And because it was conducted (...) in thought, does it not miraculously escape the need for the elaborate laboratories and bloated budgets of experimental science? These questions in effect pose the epistemological problem of thought experiments in the sciences: Thought experiments are supposed to give us information about our physical world. From where can this information come? One enticing response to the problem is to imagine that thought experiments draw from some special source of knowledge of the world that transcends our ordinary epistemic resources.

Tomasello et al. lay out a three-step ontogenetic pathway for infants' understanding of intentional action. By this account, before 9 months, infants do not understand actions as being goal directed. However, we caution against drawing strong conclusions from negative findings, and, based on recent findings, propose that a key aspect of goal knowledge is present well before 9 months.
In this paper I investigate how philosophy can speak for children and how children can have a voice in philosophy and speak for philosophy. I argue that we should understand children as responsible rational individuals who are involved in their own philosophical inquiries and who can be involved in our own philosophical investigations—not because of their rational abilities, but because we acknowledge them as conversational partners, acknowledge their reasons as reasons, and speak for them as well as let them speak (...) for us and our rational community. In order to argue this I turn, first, to Gareth Matthews' philosophy of childhood and suggest a reconstruction of some of his concepts in line with the philosophy of Stanley Cavell. Second, in order to examine more closely our conceptions of rationality and our pictures of children, I consider the children's books, The Lorax and Where is My Sister? and Henrik Ibsen's play, The Wild Duck.

It is well known that Charles S. Peirce's first attempt to construct a theory of metaphysical categories, already displaying the triadic pattern that would later become the keystone of his philosophy, directed itself towards the three English personal pronouns: I, IT, THOU.2 As many scholars have already noted, these three spheres of the phenomenal world identified by the young Peirce prelude to the 1867 "New List" (Quality, Relation and Representation) as well as to the later categories of Firstness, Secondness and (...) Thirdness.But apart from their documentary significance as the seed of Peircean metaphysics, the writings on I, IT and THOU also have a philosophical interest in their own right, one which deserves to ..

This paper proposes that human expression of pain in the presence or absence of caregivers, and the detection of pain by observers, arises from evolved propensities. The function of pain is to demand attention and prioritise escape, recovery, and healing; where others can help achieve these goals, effective communication of pain is required. Evidence is reviewed of a distinct and specific facial expression of pain from infancy to old age, consistent across stimuli, and recognizable as pain by observers. Voluntary control (...) over amplitude is incomplete, and observers can better detect pain that the individual attempts to suppress rather than amplify or simulate. In many clinical and experimental settings, the facial expression of pain is incorporated with verbal and nonverbal vocal activity, posture, and movement in an overall category of pain behaviour. This is assumed by clinicians to be under operant control of social contingencies such as sympathy, caregiving, and practical help; thus, strong facial expression is presumed to constitute an attempt to manipulate these contingencies by amplification of the normal expression. Operant formulations support skepticism about the presence or extent of pain, judgments of malingering, and sometimes the withholding of caregiving and help. To the extent that pain expression is influenced by environmental contingencies, however, “amplification” could equally plausibly constitute the release of suppression according to evolved contingent propensities that guide behaviour. Pain has been largely neglected in the evolutionary literature and the literature on expression of emotion, but an evolutionary account can generate improved assessment of pain and reactions to it. Key Words: adaptation; evolutionary psychology; facial expression; pain. (shrink)
A sample of students from a private, multicampus, midsize university completed 2 copies of Gardner and Melvin's (1988) Attitudes Toward Cheating Scale a semester before the implementation of a modified honor code. The authors instructed students to complete 1 copy of the scale according to their own opinions and the other copy according to what they thought would be the opinion of a "typical college professor." During the following semester when the honor code went into effect, the authors recruited a (...) second sample of 1st-year students and asked them to complete the 2 scales in the same manner. Although both samples of students reported attitudes toward cheating that were significantly more tolerant than the attitudes they ascribed to professors, scores were virtually identical for both samples. The authors speculate that variables associated with how the honor code was implemented, together with certain demographic characteristics of the institution, mediated the results obtained. (shrink)
A relatively small segment of business, known as social entrepreneurship (SE), is increasingly being acknowledged as an effective source of solutions for a variety of social problems. Because society tends to view "new" solutions as "the" solution, we are concerned that SE will soon be expected to provide answers to our most pressing social ills. In this paper we call into question the ability of SE, by itself, to provide solutions on a scope necessary to address large-scale social issues. SE (...) cannot reasonably be expected to solve social problems on a large scale for a variety of reasons. The first we label the orga nizational legitimacy argument. This argument leads to our second argument, the isomorphism argument. We also advance three other claims, the moral y political and structural arguments. After making our arguments, we explore ways in which SE, in concert with other social institutions, can effectively address social ills. We also present two examples of successful ventures in which SEs partnered with governments and other institutions. (shrink)
Carpendale & Lewis (C&L) propose that social knowledge is constructed from triadic interactions. This account generates testable predictions concerning social knowledge in infancy. Current evidence is not entirely consistent with these predictions. Infants possess action knowledge before they engage in triadic interactions, and triadic use of an action does not always precede knowledge about the action.
A peer instruction model was used whereby 78 residence dons (36 males, 42 females) provided instruction regarding academic integrity for 324 students (125 males, 196 females) under their supervision. Quantitative and qualitative analyses were conducted to assess survey responses from both the dons and students regarding presentation content, quality, and learning. Overall, dons consistently identified information-based slides about academic integrity as the most important material for the presentations, indicating that fundamental information was needed. Although student ratings of the usefulness of (...) the presentations were middling, students did indicate knowledge gains. Both interest and personal value for academic integrity were highly predictive of positive evaluations of the presentations. Dons and students provided suggestions for improvement and identified more global concerns. (shrink)

The latter part of the twentieth century saw the Chinese economy moving towards a socialist market economy rather than a planned system. Despite growing interest in Chinese business ethics, little work has examined ethical issues concerning the Chinese sales force. This study draws from existing work on Chinese and Western business and sales ethics to develop hypotheses regarding the perceptions of unethical selling behaviour of modern Chinese salespeople. A survey of Chinese sales executives is conducted and statistically analysed. Results are (...) compared with those reported in previous US-based research with regard to differences in perceptions of unethical selling behaviour. The results indicate that contemporary Chinese salespeople were more favourably disposed than expected towards unethical selling behaviour, and also more favourably disposed than previously studied US salespeople. Younger Chinese salespeople evaluated unethical behaviours more favourably than older ones. The results are discussed, along with implications for theory, practice and future work. (shrink)
This book investigates the nature of the relationship between phonology and syntax and proposes a theory of Minimal Indirect Reference that solves many classic problems relating to the topic. Seidl shows that all variation across languages in phonological domain size is due to syntactic differences and a single domain parameter specific to phonology.
In 300 BCE, the tutor of the heir-apparent to the Chu throne was laid to rest in a tomb at Jingmen, Hubei province in central China. A corpus of bamboo-strip texts that recorded the philosophical teachings of an era was buried with him. The tomb was sealed, and China quickly became the theater of the Qin conquest, an event that proved to be one of the most significant in ancient history. For over two millennia, the texts were forgotten. But in (...) October 1993, they were unearthed. The discovery of the Guodian texts, together with other recently discovered Warring States manuscripts, has revolutionized the study of early Chinese intellectual history. Kenneth Holloway argues that the Guodian corpus puts forth a political philosophy based on the harmonious interconnection of individuals engaged in moral self-cultivation. This unique worldview, says Holloway, cannot meaningfully be categorized as "Confucian" or "Daoist," because it shares important concepts and vocabulary with a number of different textual traditions that have anachronistically been characterized as competing or incompatible "schools" of thought. He finds that within the Guodian corpus familiar philosophical concepts and texts are applied in distinctive ways, presenting a worldview that is quite different from the received textual traditions. In the corpus, the most important function of government is to assist in the harmonization of state and family relations. It sees the relationship between these two entities - the family and the collection of families that ultimately constitute the state - as being inherently conflicting social groupings. The texts posit an interesting solution: State and family disharmony can be overcome by developing a hybrid government that employs both meritocratic and aristocratic methods. Without knowledge of the emphasis on hybridization found in the Guodian texts, however, scholars were unable to understand the interrelationships between these two methods of government. This new understanding illuminates central issues of government, religion, and philosophy in early China that were overlooked in received texts. As part of the contribution to our understanding of this particular body of texts, Holloway proposes a methodology for assessing a corpus of texts without relying on assumptions and definitions that derive from two thousand years of scholarship. The Guodian corpus, and Holloway's analysis of it, are now absolutely indispensable to any student or scholar of ancient Chinese intellectual history. (shrink)
We analyzed the variability of response in records obtained from MT (V5) of awake, behaving monkeys and kindly provided to us by Newsome and Bair (see Newsome et al 1990 for Methods). Some sets of random dot kinematograms had been generated with a constant randomization seed (novar stimuli), while others had been generated with varying randomization seeds (var stimuli). The neural responses to novar stimuli exhibited a remarkable degree of consistent temporal modulation, while the responses to var stimuli were (...) homogeneous over the presentation time. We suspected that correspondence noise might be a major source of variability and to test this we compared the variability of response to novar and var stimuli, making the assumption that the variability observed in responses to novar stimuli reflected the internal noise only, whereas variability in the case of var stimuli reflected internal noise and external noise. From this assumption, we could estimate the relative importance of external noise and internal noise in this system. The main conclusions are:- (1) Efficiency values (up to about 35%) calculated from neural responses in MT are of the same order as those of human observers, (Barlow and Tripathy 1997) (2) External correspondence noise is a significant factor in limiting the detectability of coherent motion in these random dot stimuli.

Survey data are presented on opinions about agricultural biotechnology and its applications held by agricultural science faculty at highly ranked programs in the United States with and without personal involvement in biotechnology-oriented research. Respondents believed biotech holds much promise, but policy positions vary.

Media accounts are often seen as causes, rather than artifacts, of the existence of public controversy; European and now U.S. opposition (...) to food biotechnology is often explained away in terms of such a relationship. The authors argue that where even experts are divided, public opposition cannot reasonably be attributed to poor public understanding or sensationalistic media accounts. Ethical implications for communicating science are explored. (shrink)
Judith Thomson’s “A Defense of Abortion” is one of the most widely taught papers in undergraduate philosophy, yet it is notoriously difficult to teach. Thomson uses simple terminology and imaginative thought experiments, but her philosophical moves are complex and sometimes difficult to explain to a class still mystified by the prospect of being kidnapped to save a critically ill violinist. My aim here is to identify four sources of difficulty that tend to arise when teaching this paper. In my experience, (...) these four sources of difficulty create significant problems for undergraduate students, yet each one is easy for instructors to underestimate. My objective is therefore to identify the problems, explain why they tend to occur and warn other instructors about their potential impact in the classroom. (shrink)
