In the eyes of some of its critics, disjunctivism fails to support adequately the key claim that a particular hallucination might be indistinguishable from a certain kind of veridical perception despite the two states having nothing other than this in common. Scott Sturgeon, for example, has complained that disjunctivism ‘‘offers no positive story about hallucination at all’’ (2000: 11) and therefore ‘‘simply takes [indistinguishability] for granted’’ (2000: 12). So according to Sturgeon, what the disjunctivist needs to provide is a plausible (...) explanation of just how two mental states which have no common component might be indistinguishable for their subject and this in turn will require the telling of a positive story about hallucination. This is the goal of the present essay. (shrink)
Under the general heading of what we might loosely call emotional states, a familiar distinction can be drawn between emotions (strictly so-called) and moods. In order to judge under which of these headings a subject’s emotional episode falls, we advance a question of the form: What is the subject’s emotion of or about? In some cases (for example fear, sadness, and anger) the provision of an answer is straightforward: the subject is afraid of the loose tiger, or sad about England’s (...) poor performance in the World Cup, or angry with her errant child. Although the ways we find natural to talk in such situations can alter (afraid of, sad about, angry with, and so on), in each case the emotion has what Ronald de Sousa, following Wittgenstein, calls a target—“an actual particular to which that emotion relates.” (de Sousa, 1987, p.116).

Whilst it may seem strange to ask to whom "I" refers, we show that there are occasions when it is not always obvious. In demonstrating this we challenge Kaplan's assumption that the utterer, agent and referent of "I" are always the same person. We begin by presenting what we regard to be the received view about indexical reference popularized by David Kaplan in his influential 1972 "Demonstratives" before going on, in section 2, to discuss Sidelle's answering machine paradox which may (...) be thought to threaten this view, and his deferred utterance method of resolving this puzzle. In section 3 we introduce a novel version of the answering machine paradox which suggests that, in certain cases, Kaplan's identification of utterer, agent and referent of "I" breaks down. In the fourth section we go on to consider a recent revision of Kaplan's picture by Predelli which appeals to the intentions of the utterer, before arguing that this picture is committed to unacceptable consequences and, therefore, should be avoided if possible. Finally, in section 5, we present a new revision of Kaplan's account which retains much of the spirit of his original proposal whilst offering a intuitively acceptable way to explain all of the apparently problematic data. In doing so, we also show how this picture is able to explain the scenario which motivated Predelli's account without appealing to speaker intentions. (shrink)
During the 'What is Realism?' symposium at the 2001 Joint Session, Professor Ayers raised a number of objections to the disjunctive theory of perception. However in his reply, Professor Snowdon protested that Ayers had failed to adequately engage with the disjunctivist's position. This apparent lack of engagement suggests that the terms of this debate are not as clear as they might be. In the light of this, the current paper offers a way in which we might shed light on the (...) underlying nature of the dispute between disjunctivists and non-disjunctivists, and following this, goes on to recommend ways in which the debate might then be taken forward.

Recent attempts to show that functional processing entails the presence of phenomenal consciousness have failed to deliver the kind of answers to the “problems of consciousness” that anti-materialists insist the functionalist must provide. I will illustrate this by focusing on the claims that there is a special “Hard Problem” of consciousness and an “explanatory gap” between functional and phenomenal facts. I then argue that if we supplement the functionalist stories with a relationalist conception of phenomenal properties, we can begin to (...) see the shape of a naturalistic theory of phenomenal consciousness that will provide intuitively compelling responses to these problems.

Introduction: Three key principles -- Sense datum theories -- Adverbial theories -- Belief acquisition theories -- Intentional theories -- Disjunctive theories -- Perception and causation -- Perception and the sciences of the mind -- Perception and other sense modalities.
Disjunctivism, as a theory of visual experience, claims that the mental states involved in a “good case” experience of veridical perception and a “bad case” experience of hallucination differ, even in those cases in which the two experiences are indistinguishable for their subject. Consider the veridical perception of a bar stool and an indistinguishable hallucination; both of these experiences might be classed together as experiences (as) of a bar stool or experiences of seeming to see a bar stool. This might (...) lead us to think that the experiences we undergo in the two cases must be of the same kind, the difference being that the former, but not the latter, is connected to the world in the right kind of way. Such a conjecture has been called a “highest common factor” or “common kind” assumption. At heart, disjunctivism consists in the rejection of this assumption. According the disjunctivist, veridical experiences and hallucinations do not share a common component. There are a host of interesting questions surrounding disjunctivism including: What is involved in the claims that good case and bad case experiences differ? Why might one might want to be a disjunctivist? What kinds of claims can the disjunctivist make about hallucination and illusion? These questions, and problems for the thesis, will be discussed as we proceed. (shrink)
He had made it all up, he said, and gloated that his "prank" proved that sociologists and humanists who spoke of science as a "social construction" didn't know what they were talking about. Acknowledging the ethical issues raised by his deception, Professor Sokal declared it justified by the importance of the truths he was defending from postmodernist attack: "There is a world; its properties are not merely social constructions; facts and evidence do matter. What sane person would contend otherwise?".

Fish proposes that we need to elucidate what 'disjunctivism' stands for, and he also proposes that it stands for the rejection of a principle about the nature of experience that he calls the decisiveness principle. The present paper argues that his first proposal is reasonable, but then argues, in Section II, that his positive suggestion does not draw the line between disjunctivism and non-disjunctivism in the right place. In Section III, it is argued that disjunctivism is a thesis about the (...) special nature of perceptual experience, and the thesis as elucidated here is then distinguished from and related to certain other ideas about perception, namely, direct realism and also McDowell's epistemological disjunctivism.

This paper explores the relationship between psychology and neurobiology in the context of cognitive science. Are the sciences that constitute cognitive science independent and theoretically autonomous, or is there a necessary interaction between them? I explore Fodor's Multiple Realization Thesis (MRT) which starts with the fact of multiple realization and purports to derive the theoretical autonomy of special sciences (such as psychology) from structural sciences (such as neurobiology). After laying out the MRT, it is shown that, on closer inspection, the (...) argument is either circular or self-undermining--the argument either assumes the very autonomy it seeks to demonstrate or the concluded autonomy is contradicted by the theoretical interdependence invoked by the premises of the argument. Next, I explore a concrete example of multiple realization in the explanation of animal behavior: the convergent evolution of jamming avoidance behaviors in three genera of weakly electric fish. Contrary to the image painted by the MRT, the work on these animals involves a high degree of interaction between the various levels of investigation. The fact that our understanding of electric fish behavior involves functional theories and multiple realization without the kind of disunified science that is supposed to follow from such a situation indicates that the mere fact of multiple realization cannot be the basis for an autonomous psychology.

To determine whether fish welfare matters morally, we need to know what characteristics or capacities beings need to have in order to be morally considerable, and whether fish have such characteristics. In this paper I discuss a group of theories, Kantian practical reasoning theories, in which agency (or practical rationality) is traditionally thought to be a necessary condition for moral considerability. An individual must have quite sophisticated capacities to be a (moral) agent in such theories: she must be able to (...) act on rational principles. It seems unlikely that nonhuman animals such as fish have such capacities. I argue, however, that on the basis of certain Kantian arguments, moral agents have reason to accept duties to nonrational animals if they are agents in a much less demanding sense: if they are motivated to pursue the objects of their desires. If fish have this capacity, their welfare matters morally. (shrink)
This paper explores citizens’ views about the welfare of farmed fish and the mental abilities of fish with a large survey data sample from Finland (n = 1,890). Although studies on attitudes towards animal welfare have been increasing, fish welfare has received only limited empirical attention, despite the rapid expansion of aquaculture sector. The results show that the welfare of farmed fish is not any great concern in the Finnish society. The analysis confirms the distinct character given to farmed fish (...) compared to traditional farmed animals. Salmon are rated low in their mental abilities, including the capacity to feel pain, which may weaken ethical concerns for fish welfare. When analyzing the social determinants surrounding the rating of the welfare of farmed fish, it was shown that fish welfare attitudes follow general animal welfare attitudes regarding age and place of residence as fish welfare tends to be rated more negatively among younger age groups and among urban residents. However, no clear connection could be identified between gender and the rating of fish welfare, which may suggest that the distinct cultural categorization of fish diminishes the typical gender difference identified in animal attitudes. It is concluded that in order to improve awareness about fish welfare, there is a need to increase dissemination of scientific knowledge about fish and their welfare. Moreover, further research should be directed toward studying the moral positioning of fish and the distinct moral categorization they receive. (shrink)
Aquaculture is the fastest growing animal-production sector in the world. This leads to the question how we should guarantee fish welfare. Implementing welfare standards presupposes that we know how to weigh, define, and measure welfare. While at first glance these seem empirical questions, they cannot be answered without ethical reflection. Normative assumptions are made when weighing, defining, and measuring welfare. Moreover, the focus on welfare presupposes that welfare is a morally important concept. This in turn presupposes that we can define (...) the capacities of fish, which is an empirical undertaking that informs and is informed by ethical theories about the moral status of animals. In this article we want to illustrate the need for a constant interaction between empirical scientific research and ethics, in which both fields of research make their own contribution. This is not a novel claim. However, the case of fish sheds new light on this claim, because regarding fish there is still much empirical uncertainty and there is a plurality of moral views on all levels. Therefore, we do not only want to show the necessity of this interaction, but also the added value of a cooperation between ethicists and empirical scientists, such as biologists, physiologists, and ethologists. We demonstrate this by considering the different steps in the process of reflection about and implementation of fish welfare. (shrink)
The happy fish episode from the outer chapters of the Zhuangzi poses enormous difficulty for interpreters. While it may appear to surprisingly resemble the dialectic in Western philosophy, any attempt to analyse it in terms of the patterns of inference familiar to the West is often frustrated by the ostensible queerness that defies such treatment. The following examination of the dialogue in the episode is intended to address the difficulty and to provide a reasoned explanation for both the surface resemblance (...) and apparent queerness. I suggest that the dialogue becomes perfectly intelligible, if it is read against the backdrop of the disputations practiced in ancient China. My contention is that the real purpose of the dialogue is to expose the fundamental unreliability of the logic of the disputers by means of the logic itself. (shrink)
Zhuangzi and Hui Shi's discussion about whether Zhuangzi knows 'fish's happiness' is a Daoist staple. The interpretations, however, portray it as humorous miscommunication between a mystic and a logician. I argue for a fine inferential analysis that explains the argument in a way that informs Zhuangzi philosophical lament at Hui Shi's passing. It also reverses the dominant image of the two thinkers. Zhuangzi emerges as the superior dialectician, the clearer, more analytic epistemologist. Hui Shi's arguments betray his tendency (manifest elsewhere) (...) to misstate the conclusions of their shared relativism leading him but not Zhuangzi to intuitive mysticism. (shrink)
Relativistic theories and arguments are fairly common in legal thinking. A case in point is Stanley Fish's theory of interpretation, which applies to statutes and constitutions as well as to novels and poems. Fish holds, inter alia, (i) that an interpretation of a statute, a poem, or some other text can be true or valid only in light of the interpretive strategies that define an interpretive community, and (ii) that no set of interpretive strategies (and therefore no interpretation) is truer (...) or more valid than any other. In this article, I discuss these claims critically and argue that the very idea of an interpretive community is more or less unintelligible, and that in any case Fish's theory is self-refuting. I begin with a few words about the methods and techniques of statutory interpretation(Section 2). I proceed by introducing Fish's theory of interpretation, giving special consideration to some difficulties in Fish's account of the concept of an interpretive community (Sections 3-4). I then introduce two types of relativism, cognitive and moral (Section 5), and argue that Fish's theory asserts cognitive relativism in the shape of conceptual relativism and relativism about truth (Section 6). Having done that, I consider Donald Davidson's well-known objection to alternative conceptual schemes (Section 7) as well as the popular charge that relativism about truth is self-refuting (Section 8).

Questions about fish consciousness and cognition are receiving increasing attention. In this paper, I explain why one must be careful to avoid drawing conclusions too hastily about this hugely diverse set of species.
Improvements in production methods over the last two decades have resulted in aquaculture becoming a significant contributor to food production in many countries. Increased efficiency and production levels are off-setting unsustainable capture fishing practices and contributing to food security, particularly in a number of developing countries. The challenge for the rapidly growing aquaculture industry is to develop and apply technologies that ensure sustainable production methods that will reduce environmental damage, increase productivity across the sector, and respect the diverse social and (...) cultural dimensions of fish farming that are observed globally. The aquaculture industry currently faces a number of technology trajectories, which include the option to commercially produce genetically modified (GM) fish. The use of genetic modification in aquaculture has the potential to contribute to increased food security and is claimed to be the next logical step for the industry. However, the potential use of these technologies raises a number of important ethical questions. Using an ethical framework, the Ethical Matrix, this paper explores a number of the ethical issues potentially raised by the use of GM technologies in aquaculture. Several key issues have been identified. These include aspects of distributive justice for producers; use of a precautionary approach in the management of environmental risk and food safety; and impacts on the welfare and intrinsic value of the fish. There is a need to conduct a comparative analysis of the full economic cycle of the use of GM fish in aquaculture production for developing countries. There is also a need to initiate an informed dialogue between stakeholders and strenuous efforts should be made to ensure the participation of producers and their representatives from developing nations. An additional concern is that any national licensing of the first generation of GM fish, i.e., in the USA, may initiate and frame an assessment cycle, mediated by the WTO, which could dominate the conditions under which the technology will be applied and regulated globally. Therefore, an integrated analysis of the technology development trajectories, in terms of international policy, IPR, and operational implications, as well as an analysis of a broader range of ethical concerns, is needed.

In Doing What Comes Naturally, StanleyFish argues on behalf of rhetoric and against philosophy. The latter assumes an independent reality that can be perceived without distortion and then reported in a transparent verbal medium. The former insists that this is impossible. As Fish acknowledges, this debate is a version of the ?old quarrel? that has raged since the dialogues of Plato and the orations of the sophists. The present paper first examines how the Greek sophist Isocrates (...) actually formulated the terms of the debate. Then it turns to Plato in order to demonstrate that his treatment of the old quarrel is superior to Fish's postmodern update. (shrink)
I examine the morality of sport fishing by focusing on the respect that anglers show for the interests of fish compared to the respect that hunters show for their game. Angling is a form of hunting because of the strong link between these two activities in literature, in management, and in the individual’s participation in both angling and hunting, and in the similarity of both activities during the process of pursuing an animal in order to control it. Fish are similar (...) in many ways to animals that are hunted, including their interests in survival and in avoiding pain. These interests need to be considered by anglers for moral reasons. All hunters and anglers value their sport with animals more than they respect the lives of animals they pursue. Hunters are, therefore, similar to anglers in the respect that they show for the survival interests of their game animals. Hunters, however, are significantly different from anglers in the respect that they show for an animal’s interest in avoiding pain and suffering. While hunters make every effort to reduce pain and suffering in their game animals, anglers purposefully inflict these conditions on fish. These similarities and differences have three important consequences: (1) The moral argument justifying the killing of animals for sport in hunting must apply to all of angling as well. (2) Angling, unlike hunting, requires a second justification for the intentional infliction of avoidable pain and suffering in fish. (3) If ethical hunters hold true to their principle of avoiding all suffering in the animals that they pursue, then hunters must reject all sports fishing. (shrink)
The paper starts with the assumption that the Precautionary Principle (PP) is one of the most important elements of the concept of sustainability. It is noted that PP has entered international treaties and national law. PP is widely referred to as a central principle of environmental policy. However, the precise content of PP remains largely unclear. In particular it seems unclear how PP relates to science. In section 2 of the paper a general overview of some historical and systematic features (...) of PP are presented. In section 3 a specific case is discussed in greater detail. It is claimed that the escape of farmed salmon from fish cages in the Sea, and its eventual invasion of the breeding places of the wild salmon up the rivers, must be regarded a proper case for applying PP. Yet there is no single PP-strategy. Instead, four different strategies are presented, and all of them can be regarded precautionary strategies in the light of PP. The choice between these strategies is based upon personal values. In section 4 of the paper a general analysis is given which relates these different value perspectives to basic differences in risk aversion, which in turn are related to differing conceptions of nature and/or society. In the concluding section 5 some general consequences of the foregoing analysis are outlined. (shrink)
As the world population is growing and government directives tell us to consume more fatty acids, the demand for fish is increasing. Due to declines in wild fish populations, we have come to rely more and more on aquaculture. Despite rapid expansion of aquaculture, this sector is still in a relatively early developmental stage. This means that this sector can still be steered in a favorable direction, which requires discussion about sustainability. If we want to avoid similar problems to the (...) ones we have experienced with livestock farming, we need to generate knowledge of the biology, profitability, environmental aspects, consumer awareness, and product appreciation of particular fish species. However, the discussion about a sustainable aquaculture also raises the question how we should treat fish. This moral question is regularly addressed as a problem of applied ethics with a focus on tailoring ethical principles to practical questions. In this article we do not deny the importance of the practical accounts, but we start from the fundamental question whether and why fish matter in our moral deliberations, i.e., from the discussion on moral status. We elaborate the distinction between moral considerability and moral significance in order to show both the importance and the limitations of the discussion about moral status for practical problems in aquaculture. We illustrate these points with a case-study about the farming of a specific fish species, the African catfish. (shrink)
Four aspects of Mazur & Booth's target article are discussed from a comparative perspective using teleost fish as a reference: (a) the relationship between aggression, dominance, and androgens; (b) the interpretation of the data in light of the challenge hypothesis; (c) the potential role of testosterone as a physiological mediator between social status and the expression of male characters; and (d) the fact that metabolic conversions of testosterone may be important in its effect on aggression/ dominance.
This paper is the result of a contribution between ethics and law, which will be used as thought-process tools, to address the complex issue of legal and ethical statuses of GM fish. To find answers, we propose to consider this issue from a wider angle, looking at the relations between the human, animal, and living worlds. We show that it is possible to construct other forms of intellectual logic that, without setting these worlds in opposition, do not lapse into relativism (...) where boundaries are blurred. In this sense, we submit the hypothesis that ordered pluralism should help us to move past a mere Man–Animal relationship to reveal the entire complexity of relationships within mankind and between mankind and other (non-human) worlds alongside it and to which it belongs: the animal and living worlds. With this new logic, “animal ethics” and “animal law” are re-embedded into a set of relationships. This logic emerges from a new consideration: the nature of the contemporary objects we are dealing with. We shall call objects like genetically modified fish “relational objects” in the sense that in order to be apprehended, they utilize a set of relationships of which there are just as many as the dimensions forming them, not as predicates but as primary constituents. Experimentally, in the case of GM fish, we translate this by proposing to typologize legal and ethical considerations induced by multiple relations connected to this object. According to the type of relationship in question, the GM fish will not have the same status; it is a changing object that must be suitably apprehended. (shrink)
The status of wild capture fisheries has induced many fisheries and conservation scientists to express concerns about the concept of using forage fish after reduction to fishmeal and fish oil, as feed for farmed animals, particularly in aquaculture. However, a very large quantity of forage fish is being also used untransformed (fresh or frozen) globally for other purposes, such as the pet food industry. So far, no attempts have been made to estimate this quantum, and have been omitted in previous (...) fishmeal and fish oil exploitation surveys. On the basis of recently released data on the Australian importation of fresh or frozen fish for the canned cat food industry, here we show that the estimated amount of raw fishery products directly utilized by the cat food industry equates to 2.48 million metric tonnes per year. This estimate, plus the previously reported global fishmeal consumption for the production of dry pet food suggest that 13.5% of the total 39.0 million tonnes of wild caught forage fish is used for purposes other than human food production. This study attempts to bring forth information on the direct use of fresh or frozen forage fish in the pet food sector that appears to have received little attention to this date and that needs to be considered in the global debate on the ethical nature of current practices on the use of forage fish, a limited biological resource.

This work presents a specific stock-effort dynamical model. The stocks correspond to two populations of fish moving and growing between two fishery zones. They are harvested by two different fleets. The effort represents the number of fishing boats of the two fleets that operate in the two fishing zones. The bioeconomical model is a set of four ODE's governing the fishing efforts and the stocks in the two fishing areas. Furthermore, the migration of the fish between the two patches is (...) assumed to be faster than the growth of the harvested stock. The displacement of the fleets is also faster than the variation in the number of fishing boats resulting from the investment of the fishing income. So, there are two time scales: a fast one corresponding to the migration between the two patches, and a slow time scale corresponding to growth. We use aggregation methods that allow us to reduce the dimension of the model and to obtain an aggregated model for the total fishing effort and fish stock of the two fishing zones. The mathematical analysis of the model is shown. Under some conditions, we obtain a stable equilibrium, which is a desired situation, as it leads to a sustainable harvesting equilibrium, keeping the stock at exploitable densities. (shrink)
A study of stage structured model of fish population is presented. This model focuse on the anchovy population in the Bay of Biscay (Engraulis encrasicolus L.) is presented. The method of study is based on an intermediate complexity mathematical model, taking into account the spatialisation, the environmental conditions and the stage-structure of the fishes. First, to test the model, we show mathematical properties, such as unicity of the solution of structural stability. Then we provide numerical simulations, to validate the model (...) and to test the dynamics according to the variations of the parameters. (shrink)
Elephant fish and GPS is an attempt to reflect on data flux, and artistic practice considered as a way to implement an experience specific to a flux. Sonification is particularly well suited to this type of implementation. As such, it leads us to question the nature of this type of experience, the position of the person who is faced with the artistic object, and the position and function of the artist. It allows us to query the status of devices produced (...) by such an artistic practice and the status of what is, traditionally, called a “work of art”. The approach is derived from neither the study of specific artistic projects that could be considered as examples from which a general model could be extrapolated, nor, conversely, that of the enunciation of models illustrated by concrete references. The intention is not to categorize practice or behavior. It is rather an approach that seeks to shift concepts and ways of thinking through progressive analogies aimed at critically questioning the notion of experience in a transition from “object” based logic to “flux” or “field”, based logic, coming from an aesthetic perspective.

We applaud Domjan et al. for providing an elegant account of Pavlovian feed-forward mechanisms in social behavior that eschews the pitfall of purposivism. However, they seem to imply that they have provided a complete account without provision for operant conditioning. We argue that operant conditioning plays a central role in social behavior, giving examples from fish and infant behavior.
Sustainability and welfare are concepts that are often mentioned in the context of fishing and fish farming. What these concepts imply in practice, how they are defined and made operational is less clear. This paper focuses on the role of fish buyers as a key actor in the supply chain between the fisher or fish farmer and the consumer. Using semi-structured interviews, we explore and analyze whether and how the interviewed fish buyers define and implement moral values related to animal (...) welfare and sustainability. The eight fish buyers who were interviewed suggest that moral values are used in their work, but also result in a number of value conflicts (moral and non-moral). The focus on sustainability and animal welfare appear to be driven by external and market factors. Sustainability mainly reflects fishing methods and quotas and fish welfare is seen as part of sustainability. Fish welfare seems more important for farmed than for wild fish as the buyers feel a responsibility regarding these kept animals. Further, the decision whether a product is sustainable is mainly based on labels. Fish buyers argue that labels are useful as a business-to-business tool. Nonetheless, based on the interviews, we argue that the relevance of these labels for addressing the ethical dilemmas of buyers is limited. Labels often are a rather procedural solution that deals with the genuine dilemmas only to a limited extent. We conclude that in order to move forward, the sector needs to further reflect and elaborate on its core values. (shrink)
The frequently occurring photoreceptor patterns in fish are explained using functional and environmental demands in a geometric model. The shape of the double cone provides a number of constructional properties leading to a limited number of appropriate configurations. The probability of their occurrence is estimated from the degree to which the combination of properties of each configuration meets specific environmental light conditions. A row pattern of merely double cones is especially suitable for vision in a dim homochromatic environment; a triangular (...) pattern is quite appropriate for high resolution and accurate movement detection, whereas the known square pattern has a high adaptive capacity to varying spectral distributions. In this context the transforming capacities of both square and row patterns can be understood. (shrink)
Nanoparticles have multifaceted advantages in drug administration as vaccine delivery and hence hold promises for improving protection of farmed fish against diseases caused by pathogens. However, there are concerns that the benefits associated with distribution of nanoparticles may also be accompanied with risks to the environment and health. The complexity of the natural and social systems involved implies that the information acquired in quantified risk assessments may be inadequate for evidence-based decisions. One controversial strategy for dealing with this kind of (...) uncertainty is the precautionary principle. A few years ago, an UNESCO expert group suggested a new approach for implementation of the principle. Here we compare the UNESCO principle with earlier versions and explore the advantages and disadvantages by employing the UNESCO version to the use of PLGA nanoparticles for delivery of vaccines in aquaculture. Finally, we discuss whether a combined scientific and ethical analysis that involves the concept of responsibility will enable approaches that can provide a supplement to the precautionary principle as basis for decision-making in areas of scientific uncertainty, such as the application of nanoparticles in the vaccination of farmed fish.

The last ten years have seen an increasing interest, within cognitive science, in issues concerning the physical body, the local environment, and the complex interplay between neural systems and the wider world in which they function. “Physically embodied, environmentally embedded” approaches thus loom large on the contemporary cognitive scientific scene. Yet many unanswered questions remain, and the shape of a genuinely embodied, embedded science of the mind is still unclear. I begin by sketching a few examples of the approach, and (...) then raise a variety of critical questions concerning its nature and scope. A distinction is drawn between two kinds of appeal to embodiment: ‘simple’ cases, in which bodily and environmental properties merely constrain accounts that retain the focus on inner organization and processing, and more radical appeals, in which attention to bodily and environmental features is meant to transform both the subject matter and the theoretical framework of cognitive science.

1 There is a Standard Objection to the idea that concepts might be prototypes (or exemplars, or stereotypes): Because they are productive, concepts must be compositional. Prototypes aren't compositional, so concepts can't be prototypes (see, e.g., Margolis, 1994).2 However, two recent papers (Osherson and Smith, 1988; Kamp and Partee, 1995) reconsider this consensus. They suggest that, although the Standard Objection is probably right in the long run, the cases where prototypes fail to exhibit compositionality are relatively exotic and involve phenomena (...) which any account of compositionality is likely to find hard to deal with; for example, the effects of quantifiers, indexicals, contextual constraints, etc. KP are even prepared to indulge a guarded optimism: "... when a suitably rich compositional theory... is developed, prototypes will be seen ... as one property among many which only when taken altogether can support a compositional theory of combination" (p.56). In this paper, we argue that the Standard Objection to prototype theory was right after all: The problems about compositionality are insuperable in even the most trivial sorts of examples; it is therefore as near to certain as anything in cognitive science ever gets that the structure of concepts is not statistical. Theories of categorization, concept acquisition, lexical meaning and the like, which assume the contrary simply don't work. We commence with a general discussion of the constraints that an account of concepts must meet if their compositionality is to explain their productivity. We'll then turn to a criticism of proposals that OS2 and KP make for coping with some specific cases. (shrink)
Constructivist pedagogies cannot achieve their critical thinking ambitions. Constructivism, and constructivist epistemological presuppositions, actively thwarts the critical thinking process. Using Wittgenstein's private language argument, this paper argues that corrective mechanisms—the ability to correct a student's propositions and cognitions against the background of a shared, knowable world—are indispensible to critical thinking. This paper provides concrete examples of actual constructivist practice and shows how a particular constructivist classroom exercise can be modified to incorporate critical thinking elements as detailed by the American Philosophical (...) Association. Finally, the paper states the significance of these arguments, particularly as they extend from the educational arena into the public and governmental domains. (shrink)
The Ethical Matrix was developed to help decision-makers explore the ethical issues raised by agri-food biotechnologies. Over the decade since its inception the Ethical Matrix has been used by a number of organizations and the philosophical basis of the framework has been discussed and analyzed extensively. The role of tools such as the Ethical Matrix in public policy decision-making has received increasing attention. In order to further develop the methodological aspects of the Ethical Matrix method, work was carried out to (...) study the potential role of the Ethical Matrix as a decision support framework. When considering which frameworks to apply when analyzing the ethical dimensions of the application of agri-food biotechnologies, it is important to clarify the substantive nature of any prospective framework. In order to further investigate this issue, reflections on the neologism “ethical soundness” of an ethical framework are presented here. This concept is introduced in order to provide more structured evaluations of a range of ethical tools, including ethical frameworks such as the Ethical Matrix. As well as examining the philosophical dimensions of the method, theoretical analysis and literature studies were combined with stakeholder engagement exercises and consultations in order to review the Ethical Matrix from a user perspective. This work resulted in the development of an Ethical Matrix Manual, which is intended to act as a guide for potential user groups. (shrink)
We argue that the common attribution to Zhuangzi of both perspectivalism or relativism on the one hand, and scepticism on the other is fundamentally mistaken. While granting that it is reasonable to construe Zhuangzi as offering a perspectiva! position on judgement, we argue that Zhuangzi's perspectivalism does not commit him to a relativist position on truth or to scepticism about human knowledge. Rather, we maintain that Zhuangzi's attacks on the concepts of truth and knowledge are better seen as his articulation (...) of a species of epistemological nihilism which rejects, as ultimately meaningless, the concepts of truth, reality, and knowledge.

The anecdote of Zhuangzi and Hui Shi's brief discussion on a bridge above the Hao river gives us a nice piece of reasoning in ancient Chinese texts that may serve as a platform for a productive philosophical exchange between the East and the West. The present study examines Hansen's inferential analysis of Zhuangzi and Hui Shi's discussion in this spirit. It is argued that Hansen's analysis founders. To do justice to both Hui Shi and Zhuangzi, the present study proposes that (...) we apply the logic developed in the later Mohist text, the Lesser Pick, to an analysis of their discussion. The re-analysis shows that the intricate dialectic of the reasoning in which Zhuangzi and Hui Shi engage, neatly accords with the pattern of discourse expounded in the Lesser Pick, and gives us global insight into Zhuangzi's final statement in the anecdote, which is notoriously recondite, or confusing.

The aim of this review is to assess the ethical implications of finfish aquaculture, regarding fish welfare and environmental aspects. The finfish aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas (...) of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists. However, most biologists are at present acknowledging the probability of fish being sentient creatures. Current aquaculture practices are affecting fish welfare during all four of the cited stages, both on physical and mental levels, as well as on the ability of fish to carry out natural behaviors. The effect fish farming has on the environment is here separated into five different categories: the decline of wild fish populations; waste and chemical discharge; loss of habitat; spreading of diseases; and invasion of exotic organisms. There is evidence of severe negative effects on the environment when looking at these five categories, even when considering the difficulty of studying environmental effects, due to the closely interacting variables. The ethical arguments and scientific evidences here reviewed have not all come to the same conclusions. Nevertheless, the general agreement is that current aquaculture practices are neither meeting the needs of fish nor environment. Thus, the obvious environmental and animal welfare aspects of finfish aquaculture make it hard to ethically defend a fish diet. (shrink)
What happens when management consultants enter the academic arena and offer their services to universities? In the following article, we examine this question by drawing on findings from a qualitative study based on a series of 30 interviews with senior management consultants and academic managers in Germany. The aim of this explorative study is, first of all, to provide theoretically informed observations about the working mechanisms of management consulting in academia. A second, and related objective, is to contribute to the (...) ongoing debate on the changing nature, role, and implications of managerial expertise and authority in higher education institutions. We begin our study by providing an overview of the literature on the changing nature of university management. Although these studies show a shift in the power constellation of universities from professional to managerial authority, we argue that they remain suspiciously vague as concerns the way academics and managers actually deal with this conflicting situation. By drawing on the insights of consulting studies, we then explore the stakes of consultancy in academic change projects and determine the analytical factors that will guide our qualitative analysis. Finally, we present and discuss the findings before concluding with more general remarks on the nature of academic management in German universities. (shrink)
