The use of biotechnology in food productiongives rise to consumer concerns. The term ``consumerconcern'' is often used as a container notion. Itincludes concerns about food safety, environmental andanimal welfare consequences of food productionsystems, and intrinsic moral objections againstgenetic modification. In order to create clarity adistinction between three different kinds of consumerconcern is proposed. Consumer concerns can be seen assigns of loss of trust. Maintaining consumer trustasks for governmental action. Towards consumerconcerns, governments seem to have limitedpossibilities for public policy. Under current (...) WTOregulations designed to prevent trade disputes,governments can only limit their policies to 1) safetyregulation based upon sound scientific evidence and 2)the stimulation of a system of product labeling. Ananalysis of trust, however, can show that ifgovernments limit their efforts in this way, they willnot do enough to avoid the types of consumer concernsthat diminish trust. The establishment of a technicalbody for food safety – although perhaps necessary –is in itself not enough, because concerns that relatedirectly to food safety cannot be solved by ``pure''science alone. And labeling can only be a good way totake consumer concerns seriously if these concerns arerelated to consumer autonomy. For consumer concernsthat are linked to ideas about a good society,labeling can only provide a solution if it is seen asan addition to political action rather than as itssubstitution. Labeling can help consumers take uptheir political responsibility. As citizens, consumershave certain reasonable concerns that can justifiableinfluence the market. In a free-market society, theyare, as buyers, co-creators of the market, andsocietal steering is partly done by the market.Therefore, they need the information to co-create thatmarket. The basis of labeling in these cases, however,is not the good life of the individual but thepolitical responsibility people have in their role asparticipants in a free-market. Then, public concernsare taken seriously. Labeling in that case does nottake away the possibilities of reaching politicalgoals, but it adds a possibility. (shrink)

The combination of breeding for increased production and the intensification of housing conditions have resulted in increased occurrence of behavioral, physiological, and immunological disorders. These disorders affect health and welfare of production animals negatively. For future livestock systems, it is important to consider how to manage and breed production animals. In this paper, we will focus on selective breeding of laying hens. Selective breeding should not only be defined in terms of production, but should also include traits related to animal (...) health and welfare. For this we like to introduce the concept of robustness. The concept of robustness includes individual traits of an animal that are relevant for health and welfare. Improving robustness by selective breeding will increase (or restore) the ability of animals to interact successfully with the environment and thereby to make them more able to adapt to an appropriate husbandry system. Application of robustness into a breeding goal will result in animals with improved health and welfare without affecting their integrity. Therefore, in order to be ethically acceptable, selective breeding in animal production should accept robustness as a breeding goal. (shrink)

Thanks to developments in genomics,dietary recommendations adapted to genetic riskprofiles of individual persons are no longerscience fiction. But what are the consequencesof these diets? An examination of possibleimpacts of genetically tailor-made diets raisesmorally relevant concerns that are analogous to(medical-ethical) considerations aboutscreening and testing. These concerns oftengive rise to applying norms for informedconsent and for the weighing of burdens andbenefits. These diets also have a broaderimpact, especially because food patterns arefull of personal, social and cultural meanings.Diets will change one's food patterns (...) and one'sattitude towards food, and this may implychanges in one's identity. We argue that suchan impact does not necessarily raise moralproblems. Moral concerns are, however, relevantif collective values and shared meanings infood practices are at issue. Therefore, thedevelopment of genetically tailor-made dietsdoes not merely require emphasis on weighingpersonal benefits and burdens and on informedconsent. It also asks for attention to andmoral reflection on the collective valuesinvolved in food practices. (shrink)

The purpose of this book is to examine and explicate a definition given in Philosophical Investigations. The definition of the meaning of a word is that "the meaning of a word is its use in the language." Hallett understands this as a definition in the strict sense of the word. In Chapter I, the author looks to the Tractatus for its treatment of the picture theory of meaning and the Bedeutung/sinn distinction. The conclusion which he pulls from the early work (...) is that, for Wittgenstein, meaning was already in a proposition by way of the meaning of names. Yet, only in the use or application, i.e., in a proposition with sense is meaning revealed. Although the Tractatus is far from saying that meaning is use, certain guiding themes are elaborated and carried into later works; namely, the search for meaning, the impossibility of meaning outside use, and meaning as revealed by use. Chapter II, III, and especially IV bear the brunt of establishing Hallett’s thesis that Wittgenstein presented a significant and sound definition. He begins by showing what Wittgenstein proved meaning not to be: meaning is not images, objects, mental referents, nor feelings. All of these theories have convincing confirmation in certain respects, yet analysis, i.e., observation of the actual working of language, shows each to be too narrow. In making his transition to the true definition, the author shows Wittgenstein elaborating the theses that meaning is to be found in the system or context of language. These are elaborated only to be cast aside as were the previous suggestions. The pattern elicited from these examinations is that meaning is use and, hence, defined as such. To explicate the definition, Hallett presents and examines seven characteristics of use: complexity, regularity and utility, abstraction, openness, vagueness, variety, and family resemblances. The book concludes with a consideration of the major objections to Wittgenstein’s definition. There are too many objections presented to be handled justly. For the most part, the argument is superficial, usually presuming a familiarity with the issue, and with but an indication of how the objection could be handled. The strength of the book is that it gives an organization to Wittgenstein’s later thinking, especially by way of the above-mentioned seven characteristics. In identifying and elucidating them, Hallett does Wittgenstein students a great service. Its chief weakness, although pale in regard to the overall worth, is that the main thesis is not firmly established. To say that a precise and complete definition is given is contrary to what is maintained throughout the Investigations, and perhaps a serious misreading of the German word, erklaren, as the precise English phrase, "to define." There are extensive notes and an adequate index.—W. A. F. (shrink)

Ludwig Wittgenstein concludes his Tractatus with the injunction, "What we cannot speak about we must pass over in silence." As the concluding proposition of a tersely written, tightly organized work, the reader would expect it to have a strong bite. Yet the statement has been variously ignored, dismissed, and misunderstood, interpreted as the inspired words of a mystic or as the final banishing of metaphysics from philosophical discourse. It is with the help of Janik and Toulmin’s work that it becomes (...) clear how the proposition serves as the crown to a book which Wittgenstein maintained was primarily an ethical work. In presenting the Viennese Weltanshauung [[sic]] of the late nineteenth and early twentieth century, there emerges the picture of a society where appearances ruled in all areas of cultural life, in the government, and in the arts. Viennese society was characterized by a vast impotent bureaucracy, the Strauss waltz, and the feutillion. The leader in the inevitable reaction was Karl Kraus. He instigated a critique of Viennese society through an ingenious and refined use of cultural modes of expression. Along with him, leaders emerged for each of the special arts, language, music, architecture, painting, sculpture, who, in their own particular role, tried to restore truth and responsibility to the affairs of men. The development of the characters and the issues involved make this book important. Of lesser value, unfortunately, are the chapters dealing specifically with the work of Wittgenstein, who is represented as one of the emergent leaders. Although we are rhetorically persuaded that his talk of "simples," "representation," "depicting," or "language games" is tied up with the critique of a fundamentally sophistical intellectualism, we are not led on to seeing how the critique was carried out.—W. A. F. (shrink)

The book is published in the International Library of Philosophy and Scientific Method. It proceeds under the assumption that the Tractatus and the later works of Wittgenstein are mutually illuminating. The general program is to present the Tractarian picture theory, to explain why it was abandoned and a new theory of language adopted, and to explicate the new theory of use. Conceptually the book is arranged around the problem of intentionality. Bogen believes that Wittgenstein’s chief concern was with the problem (...) of false belief. (shrink)

Reilly approaches his topic by presenting the spirit of science and the phases of scientific inquiry as Peirce saw it, keeping before the reader, at all times, Peirce’s overarching view of man and the universe. The two prevailing themes guiding Peirce’s thought are 1) that there is a special conformity of the human mind to nature and of nature to God, and 2) that there is an architectonic qualifying all the various types and levels of treatment which occupy the philosopher’s (...) interest. The first question examined is the nature of the scientific concern. For Peirce, the scientist’s spirit is marked by the pure love of knowledge. It is important to note the theoretical aspect because it explains the possibility of holding belief in abeyance while examining nature: the purity of motive allows that proper questions will be asked and errors will be readily corrected. The scientist’s purpose is the real truth of things; he begins with questions about the world. There are four stages of scientific method: 1) The scientist observes nature as a thinking, analytic inquirer. Observation presupposes that nature is intelligibly structured. 2) He formulates an explanatory hypothesis which is a process of bringing a manifold of characters to a unified whole. 3) By deduction, the inquirer gathers experiential consequents of the hypothesis. 4) By induction the question is put to nature and observed phenomena are matched to the predicted phenomena, resulting in either truth or a modified hypothesis. Peirce’s principle of the kinship of man’s mind to nature supports his dictum to follow instinct over reasoned likelihood in choosing hypotheses. Also important is the doctrine of moderate fallibilism which holds that there is a convergence upon the truth founded upon the regularity of nature, but that chance is a real factor due to nature’s evolution. Reilly’s book gives an adequate account of the aspects of Peirce’s scientific method sacrificing specific and detailed analysis to a more general approach wherein he shows the unity operative throughout Peirce’s thinking. A good index and copious notes are provided.—W. A. F. (shrink)

Suppose “chicken” eggs could be produced by quasi‐chickens—genetically engineered humps of living chicken‐flesh that do nothing but lay eggs. Would there be anything amiss with that? Animal ethicists invoke the notion of animal integrity in order to give intellectual content to the intuition that there would be. On inspection, ‘integrity’ isn't everything its proponents want it to be. Yet there's enough in it to make reasoned argument possible.

Results of studies that cast doubt on the safety of genetically modified crops have been published since the first GM crop approval for commercial release. These ‘alarming studies’ challenge the dominant view about the adequacy of current risk assessment practice for genetically modified organisms. Subsequent debates follow a similar and recurring pattern, in which those involved cannot agree on the significance of the results and the attached consequences. The standard response from the government—a reassessment by scientific advisory bodies—seems insufficient to (...) bring the debate to a satisfactory closure. The recurrence of the same debate every time an alarming study is published shows that science alone cannot solve the problem. We believe that further analysis is needed to investigate if and how we can prevent this repetitive cycle that creates frustration amongst all stakeholders. In this paper, we analyse the dynamics behind discussions which occur following alarming studies. We will use a selection of representative alarming GMO case studies to underpin our claim that it is likely that there will be a permanent difference in view of opinion that cannot be solved with more data or new facts. The current strategy of more research is a pitfall that is unlikely to solve this issue. Instead, the focus of the GM crop discussion should shift towards managing permanent different viewpoints and providing a platform for a broader conversation on agriculture and food production.

This special issue of the Journal of Agricultural and Environmental Ethics presents so-called ethical tools that are developed to support systematic public deliberations about the ethical aspects of agricultural biotechnologies. This paper firstly clarifies the intended connotations of the term “ethical tools” and argues that such tools can support liberal democracies to cope with the issues that are raised by the application of genetic modification and other modern biotechnologies in agriculture and food production. The paper secondly characterizes the societal discussion (...) on agricultural biotechnology and defends the thesis that normative perspectives fuel this discussion, so one cannot come to grips with this discussion if one neglects these perspectives. The paper thirdly agrues that no such thing exists as “one” societal debate in which these issues should be discussed. There are several interwined debates, and different actors participate in different discourses. Some practical instruments are necessary in order to include the right issues in these debates. These instruments will be coined as “ethical tools,” since they are practical instruments that can be used (tools) in order to support debates and deliberative structures for a systematic engagement with ethical issues (hence, ethical tools). Finally, the paper clarifies the ethics of these ethical tools and presents the tools as discussed in the remainder of this special issue: 1) tools to include ethical issues in public consulation and involvement; 2) tools to support systematic reflection upon ethical issues in decision-making; and 3) tools to support explicit communication about values in the food chain.

Synthetic biology aims at designing biological systems, at building ‘living machines’. The emergence of synthetic biology has reignited the cycle of public debate. The old biotechnology debate is being reiterated and the controversies are deepened. The societal debate follows the technological hype cycle. A new technology with a high visibility and high expectations also raises high controversies. For synthetic biology, this hype is currently near its peak and the first signs of disillusionment are getting visible. In policy development, on the (...) other hand, synthetic biology is in the early stages. Governments examine the need for adaptations to existing regulatory frameworks. There is a gap between the visibility of the technological developments and policy formulation. This gap is crucial for technology assessment: while the hype in public attention is over, essential policy steps are taken. In order to close this gap, technology assessment needs to facilitate the societal–ethical debate when media attention, and thus the visibility of the technological developments, declines. (shrink)

Consumer concerns pop up. They are relatedto the safety of agrifood products for people, foranimals, and for the environment as well as the socialand ethical implications of certain agrifoodproduction methods. At first sight, the WTO agreementand the SPS and TBT agreements appear to offersufficient legal scope to deal with these concerns andresolve trade conflicts. The events of recent years,however, have shown the limitations of theseagreements in dealing with cultural differencesbetween nations and in dealing with the social andpolitical pressure on national (...) governments to lay downrestrictive, trade distorting measures. It is vitalthat we consider the dynamic relationship betweennational governments, civil society, and the market.In the United States, Canada, and Europe, thisrealization is growing. We propose that these issuesshould be studied by experts in several disciplines:technical experts, hygiene experts and veterinarians,public administration experts, lawyers, philosophers,ethicists, sociologists, and, of course, economists.To unite these disciplines and provide a platform fordiscussion in the light of international tradeliberalisation, the cultural identity of distinctcommunities, and the functioning of the democraticnation state an international network is needed. Wetherefore propose establishing a network to explorethe issues and dynamics described above. The networkshould be international and interdisciplinary withparticipants, initially, from science and government.The purpose of the network would be to present newperspectives to the negotiating parties in the nextWTO round. The first steps to development of thisnetwork have since been taken and an initial group hasbeen established. (shrink)

Three types of concern for animal welfare are widelyheld: Animals should feel well, they should function well, andthey should lead natural lives. The paper deals with a well-knownanswer to the question of why such concerns are morallyappropriate: Human beings have direct duties towards animals,because animals are beings that can flourish, the flourishing ofanimals is intrinsically or inherently valuable, and that whichis conducive to their flourishing is a legitimate object of moralconcern. Looking for a tenable conception of direct dutiestowards animals, the (...) following questions are discussed: Whatshould we take it to mean that ``animal flourishing isintrinsically or inherently valuable?'''' Under what conditions doesa living being''s ability to flourish create direct duties towardsthis being? Is awareness or sentience required for there to bedirect duties towards a living being? Does such a requirementimply that moral concerns for animals would be limited to theirfeeling well, or does it also give way to having moral concernsfor their functioning well and leading natural lives? Can onetake into account considered judgements that claim that towardsdifferent animals we have moral duties that differ in kind and/orstrength? If environmental ethics cannot be based on theconception of direct duties here discussed, should one draw adistinction between duties towards ourselves, our fellow humanbeings, or animals, and duties regarding plants, or collectiveentities such as populations, species, and ecosystems?

The notion of Dignity of Creatures has been voted into the Swiss Federal Constitution by a plebiscite. Philipp Balzer, Klaus-Peter Rippe, and Peter Schaber have given an expert opinion for the Swiss government to clarify the notion of Dignity of Creatures. According to them, by voting this notion into the Swiss constitution, the Swiss have chosen for a limited biocentric approach towards biotechnology. In such an approach genetic engineering of non-human beings is only allowed insofar that their own good is (...) not impaired. It is, however, not clear when the good of a non-human being is impaired. I defend the position that – even if we confine ourselves to animals – their good goes beyond their well being. (shrink)

Food trade is of economic importance for both developed and developing countries. Food, however, is a special commodity. Firstly, the lack of food -- hunger, under-nourishment, and starvation -- is one of the world's pressing moral problems. But food is not only special because it is necessary for our survival; food is also special because it is strongly related to our social and cultural identity. Two recent transatlantic trade conflicts over food -- over the use of artificial growth hormones in (...) beef production and over the use of biotechnology in food production -- show that food is a specific commodity. In these trade-conflicts, the obligations flowing from free-trade treaties collide with the cultural and social meanings of food. Current international trade agreements neglect this point and force countries to fight their case in the field of food safety science. This causes a bias in the discussion. Europe's resistance towards artificial growth hormones and GM-food is not strictly science based; it is also culture based. For a fair resolution of trade-conflicts, this needs to be accommodated in international trade legislation. With the help of the notion of public reason I defend that precaution with regard to scientific uncertainty, and the possibility for compulsory labelling with regard to sensitive non-nutritional properties of foodstuffs, need to be incorporated in international food trade regulations.

In this paper, we present and defend the theoretical framework of an empirical model to describe people’s fundamental moral attitudes (FMAs) to animals, the stratification of FMAs in society and the role of FMAs in judgment on the culling of healthy animals in an animal disease epidemic. We used philosophical animal ethics theories to understand the moral basis of FMA convictions. Moreover, these theories provide us with a moral language for communication between animal ethics, FMAs, and public debates. We defend (...) that FMA is a two-layered concept. The first layer consists of deeply felt convictions about animals. The second layer consists of convictions derived from the first layer to serve as arguments in a debate on animal issues. In a debate, the latter convictions are variable, depending on the animal issue in a specific context, time, and place. This variability facilitates finding common ground in an animal issue between actors with opposing convictions. (shrink)

Let g E(m, n)=o mean that n is the Gödel-number of the shortest derivation from E of an equation of the form (m)=k. Hao Wang suggests that the condition for general recursiveness mn(g E(m, n)=o) can be proved constructively if one can find a speedfunction s s, with s(m) bounding the number of steps for getting a value of (m), such that mn s(m) s.t. g E(m, n)=o. This idea, he thinks, yields a constructivist notion of an effectively computable function, (...) one that doesn't get us into a vicious circle since we intuitively know, to begin with, that certain proofs are constructive and certain functions effectively computable. This paper gives a broad possibility proof for the existence of such classes of effectively computable functions, with Wang's idea of effective computability generalized along a number of dimensions.

This book is an intellectual biography of Ludwig Wittgenstein covering the decade following the First World War. For the most part the work is narrated after the fashion of a field research journal and is filled with incidents and anecdotes that are new to Wittgenstein lore. The book has three major sections. The first discloses previously unrevealed aspects of Wittgenstein’s character and personal life with the open shamelessness common to contemporary writers. The second part is devoted to a consideration of (...) "Der Satz," Wittgenstein’s preferred title for the Tractatus. Bartley claims that the main thrust of the work was a theme common to the major turn-of-the-century German and Austrian writers, Hofmansthal, Karl Kraus, Kafka, and Mauthner, namely, that "speech was becoming a vehicle not of communication but of mendacity and pointlessness". Bartley hopes to show how Wittgenstein’s "significant silence" is effected not by forging a classic of epistemological empiricism nor by writing a Kantian treatise but rather through an explication of the pre-Kantian belief that somehow language mirrors the world.

European animal disease policy seems to find its justification in a “harm to other” principle. Limiting the freedom of animal keepers—e.g., by culling their animals—is justified by the aim to prevent harm, i.e., the spreading of the disease. The picture, however, is more complicated. Both during the control of outbreaks and in the prevention of notifiable, animal diseases the government is confronted with conflicting claims of stakeholders who anticipate running a risk to be harmed by each other, and who ask (...) for government intervention. In this paper, we first argue that in a policy that aims to prevent animal diseases, the focus shifts from limiting “harm” to weighing conflicting claims with respect to “risks of harm.” Therefore, we claim that the harm principle is no longer a sufficient justification for governmental intervention in animal disease prevention. A policy that has to deal with and distribute conflicting risks of harm needs additional value assumptions that guide this process of assessment and distribution. We show that currently, policies are based on assumptions that are mainly economic considerations. In order to show the limitations of these considerations, we use the interests and position of keepers of backyard animals as an example. Based on the problems they faced during and after the recent outbreaks, we defend the thesis that in order to develop a sustainable animal disease policy other than economic assumptions need to be taken into account.
