The inherent normativity of HTA can be conceptualized as a result of normative commitments, a concept that we further specify to encompass moral, epistemological and ontological commitments at play in the practice of HTA. Based on examples from literature, and an analysis of the example of assessing Non-Invasive Prenatal Testing (NIPT), we will show that inevitable normative decisions in conducting an assessment commits the HTA practitioner to moral (regarding what makes a health technology desirable), ontological (regarding which effects of health (...) technology are conceivable), and epistemological (regarding how to obtain reliable information about health technology) norms. This highlights and supports the need for integrating normative analysis and stakeholder participation, providing guidance to HTA practitioners when making normative choices. This will foster a shared understanding between those who conduct, use, or are impacted by assessments regarding what are conceivable and desirable outcomes of using health technology, and how to collect reliable information to assess whether these outcomes are (going to be) realized. It also provides more insight into the implications of different normative choices. (shrink)

Unbelievable Errors defends an error theory about all normative judgements: not just moral judgements, but also judgements about reasons for action, judgements about reasons for belief, and instrumental normative judgements. This theory states that normative judgements are beliefs that ascribe normative properties, but that normative properties do not exist. It therefore entails that all normative judgements are false. -/- Bart Streumer also argues, however, that we cannot believe this error theory. This may seem to be a problem for the (...) theory. But he argues that it makes this error theory more likely to be true, since it undermines objections to the theory and it makes it harder to reject the arguments for the theory. -/- He then sketches how certain other philosophical theories can be defended in a similar way. He concludes that to make philosophical progress, we need to make a sharp distinction between a theory's truth and our ability to believe it. (shrink)

ArgumentWe expand upon the notion of the “credibility cycle” through a study of credibility engineering by the food industry. Research and development (R&D) as well as marketing contribute to the credibility of the food company Unilever and its claims. Innovation encompasses the development, marketing, and sales of products. These are directed towards three distinct audiences: scientific peers, regulators, and consumers. R&D uses scientific articles to create credit for itself amongst peers and regulators. These articles are used to support health claims (...) on products. However, R&D, regulation, and marketing are not separate realms. A single strategy of credibility engineering connects health claims to a specific public through linking that public to a health issue and a food product. (shrink)

There is a complicated relation between social and political inertia – the failure of institutions to respond adequately to social, technological and environmental change – and social acceleration – the tendency of social change to go faster and faster. Social stasis and acceleration are not simply opposed but also causally related. This article contrasts two theories of political and social inertia. Francis Fukuyama argues that political inertia is a result of a cognitive and institutional rigidity which is ultimately grounded in (...) human nature, and that therefore inertia is a feature inherent in political systems. Hartmut Rosa, by contrast, sees inertia as a specifically modern phenomenon, which is the result of the inability of political institutions to cope with the accelerating rate of change in other social systems. It will be argued that a broad approach combining historical, institutional and normative perspectives is needed to explain political inertia. (shrink)

Abstract: The Gricean theory of conversational implicature has always been plagued by data suggesting that what would seem to be conversational inferences may occur within the scope of operators like believe , for example; which for bona fide implicatures should be an impossibility. Concentrating my attention on scalar implicatures, I argue that, for the most part, such observations can be accounted for within a Gricean framework, and without resorting to local pragmatic inferences of any kin d. However, there remains a (...) small class of marked cases that cannot be treated as conversational implicatures, and they do require a local mode of pragmatic interpretation. (shrink)

Despite clear legislative and judicial support, a well established ethical consensus, and increased efforts at information dissemination and education, proxy decision making for incapacitated patients continues to produce moral muddle and poor resolutions in end-of-life care.In her analysis of the proxy-doctor relationship, Nancy Dubler spells out the institutionalized patterns that keep the promise of proxy directives so often unrealized. Facing medically complex care of an incapacitated patient, health care teams are apt to view the proxy as a potentially indecisive or (...) unrealistically demanding decision-maker, less a stand-in for the patient than an interloper whose improper, misguided, or self-interested decisions will work against the patient's best interests. So perceived, proxies are routinely relegated to the edges of care planning discussions, left relatively uninformed and unconsulted, and then suddenly thrust center stage to face decisions they find overwhelming. Confronting such decisions, proxies need support and compassion. What they often find is isolation and distrust, a web of professional and institutional practices that trammel their efforts to understand and execute their role. (shrink)

Many philosophers claim that it cannot be the case that a person ought to perform an action if this person cannot perform this action. However, most of these philosophers do not give arguments for the truth of this claim. In this paper, I argue that it is plausible to interpret this claim in such a way that it is entailed by the claim that there cannot be a reason for a person to perform an action if it is impossible that (...) this person will perform this action. I then give three arguments for the truth of the latter claim, which are also arguments for the truth of the former claim as I interpret it. (shrink)

Conditional sentences with quantifying expressions are systematically ambigous. In one reading, the if -clause restricts the domain of the overt quantifier; in the other, the if -clause restricts the domain of a covert quantifier, which defaults to epistemic necessity. Although the ambiguity follows directly from the Lewis- Kratzer line on if, it is not generally acknowledged, which has led to pseudoproblems and spurious arguments.

In this volume, Geurts takes discourse representation theory (DRT), and turns it into a unified account of anaphora and presupposition, which he applies not only to the standard problem cases but also to the interpretation of modal expressions, attitude reports, and proper names. The resulting theory, for all its simplicity, is without doubt the most comprehensive of its kind to date. The central idea underlying Geurts' 'binding theory' of presupposition is that anaphora is just a special case of presupposition projection. (...) But this is only one of the ways in which the concept of presupposition is taken beyond its traditional limits. Geurts shows, furthermore, that presupposition projection is crucially involved in several phenomena that are not usually viewed in presuppositional terms, such as modal subordination, de re readings of attitude reports, and rigid designation. While making his case for DRT and the binding theory, Geurts also presents an incisive analysis of what is probably still the most influential account of presupposition, viz. the satisfaction theory, demonstrating that there are fundamental problems not only with this theory but with the very framework in which it is couched.

The discussion concerning the patenting of academic knowledge is already closed for many people. It has become a type of credo, solemnly intoned at all levels: universities must commercially valorize the knowledge that they generate as extensively as possible.The public means that are reserved for universities can never increase at the same rate as the mounting costs for highly specialized research. So universities, if they want to work at the top level, must increasingly appeal to private resources. Universities are increasingly (...) forced to aim at contract research, sponsorships, commercialised service, the patenting of technical findings, and spin-offs: Cash for knowledge!The pressure for the unfettered commercialisation of academic knowledge does not only come from within the universities. The message also comes from the politicians and those who are committed to economic prosperity. They argue that the commercialisation of intellectual property contributes to new employment because it makes new industrial developments possible and reinforces the competitiveness of ventures. They make it seem that universities form the motor of the knowledge economy.In a country without considerable natural resources and with extremely high personnel costs, innovation is of vital importance. Few convictions are equally as expressly avowed at so many differing forums. The direction of the march seems clear.It was once different. The knowledge that was acquired, deepened, preserved, and transmitted within the universities was not for sale. In fact, its sale could present difficulties because academic knowledge has never answered to the properties of a marketable thing. Use does not deplete knowledge and if you consider it your mission to bring to light knowledge, you do not want to exclude anyone from making use of it.Academic knowledge could thus not be an object of trade, at least so long as nobody was intent on keeping that knowledge secret, and so long as nobody appealed to regulations, whereby one could restrict the legal use of that knowledge. Today neither of these strategies are taboo within academic centres. The patenting of all forms of qualifying knowledge is even encouraged.A patent assumes, on the one hand, that one makes public the knowledge upon which a technique rests, while one, on the other hand, can grant use of that technique exclusively to who one gives a licence, whether or not for a fee. This system is put forth as attractive for all parties. The researchers can keep up with technical details, and the entrepreneur can commercialise the finding. Everyone is happy.Or perhaps not? Are there reasons to be concerned that universities must increasingly submit themselves to the laws of the market? Are there arguments for evaluating academic performance differently than the performance of entrepreneurs? Must one regret that knowledge is commercialised as much as possible?The proponents of the commercial orientation point out that all kinds of new incentives will give a new impetus to the old academic system and will increase the relevance of academic research. They seem to dismiss resistance to the renewal as a nostalgic outpouring of a privileged group that used to have it too good, a group that for too long knew to retreat too safely back into a series of unworldly problems.The opponents of the economically oriented approach fear that the proper character of the academic mission will be lost. They fear that the loss of academic autonomy will make the specific function that a university fulfils within society impossible. In what sense?In our society, there is not one type of sphere, and there is not one valid set of standards, the basis upon which performances are evaluated, functions are judged, or objectives commended. There are strongly divergent spheres and each have their own specific function. The laws that apply in one sphere do not necessarily have authority in another sphere, and the standards that apply in one sort of relationship often have little or no meaning in another relationship.Each sphere recognises its own standards and answers to its own system of exchange for compensation, approval, and recognition. What applies in the sphere of law does not necessarily apply in the sphere of someone’s personal friendships, or is not applicable among family members. What applies in trade does not necessarily apply in the sphere of art.Even more, things go wrong when the autonomy of these spheres is not respected. Within the domain of art, love and friendship, monetary laws are not valid, at least in a healthy situation. That is not to say that the rules that apply within the free market would be wrong or unethical – far from it. It seems self evident that these laws are valid under the condition that they apply in the environment to which they belong, and that one respects these limits.This applies for all spheres. It would be unjust if one would apply the standards of friendship to the spheres of jurisprudence or education. Manifestly, it seems self evident not to define justice as a univocal principle that must be extended with the same consistency in every type of sphere. Rather, it is just to respect the individual character of the normative relationship that applies in the diverse spheres of life, and to prevent one sphere from colonising another.Justice assumes that one prevents the political sphere from stipulating what must be said, or concealed, within the academic sphere. Academics must answer alone to that which is expected of them within the academic sphere. Political pressure may exert no influence on this. Why cannot one say the same about economic pressure?Do we run the risk that the economic sphere will colonise the academic sphere just as the economic sphere previously colonised the sphere of media? What must one imagine in this supposed risk? In what sense should economic laws threaten the academic sphere?In the academic sphere, it is traditional to follow one’s own interests and investigate anything whatsoever without having to ask if this knowledge is useful for something or how the fruits of this research fit within the economic context. The academic search for a better understanding of everything has an unconditional character.The manner in which researchers evaluate the performance of each other seldom has to do with the economic effects that their findings have, but with their reliability, the meticulousness with which they were checked, the scrupulousness with which the sources were collected, and the honesty with which they were communicated. The function of the academic is to collect and refine knowledge, and to bring to light the truth.By doing so, universities offer a type of foot-hold within society. They make it possible that a place exists where one can be obedient to what lets itself appear most truthfully today. Nobody has to fear, at least as long as the autonomy of the academic sphere is respected, that the communication of a particular subject was rhetorically coloured in function of a commercial interest, was applied according to the wishes of the sponsor, was brought into conformity with what was agreed upon by the financiers, or answered to the demands of a patent.It is possible that the influence of the commercial sphere shall be less dramatic than pessimistic academics imagine, but nothing indicates the opposite. Today we are giving a new strategy power, and nobody knows how the magician’s apprentice will bring it off.This forms the context of the questions that we shall try to answer together this number of Ethical Perspectives, and we will restrict our discussion to patents. We are aware that the discussion about patents illuminates just one part of the problems, which have to do with the relation of the worlds of academia and commerce. But there is a reason for confining oneself to an aspect of this problematic relationship. If one were to broaden the scope of inquiry further, one would risk missing the complexity of the subject matter already covered, and be consigned to a far too general and aimless debate.We have brought together a number of specialists, jurists, ethicists, and people with practical experience with the field. They shall introduce us into the problematic, confront us with their points of view, and help to answer our questions: Are there moral limits to the patenting of academic knowledge? Is patenting always the most efficient strategy? Does not perhaps the university sell its soul if it gradually leaves itself subject to the laws of the market?We will begin by asking how in particular a university should proceed with the patenting of knowledge. Modern universities were inspired by the ideals of the Enlightenment, which was characterised by the open distribution of unselfishly pursued knowledge.The privatisation and commercialisation of knowledge would seem to conflict with this traditional vision. Jürgen Mittelstrass and Bart Pattyn provide a theoretical and historical basis for protecting the autonomy of university research from the corrupting aspects of the market economy.But, are there reasons for giving up the traditional outlook? Few or no universities have not chosen to patent discoveries, but how is one to proceed within the framework of the university, once one has obtained patent protection? Can one pursue a policy of using these protected intellectual rights to secure the fruits of knowledge for financially weaker groups, or do circumstances compel the universities to be exclusively driven by market forces?Those are the kinds of questions that Gilles Capart and Geertrui Van Overwalle of the KU Leuven will deal with.Sigrid Sterckx of the university of Ghent will answer the question: can patents be morally justified?Paul Belleflamme of the Université Catholique de Louvan La Neuve writes concerning the economic evidence of patents, and the real effect of incentives. Are there any economic facts that can demonstrate the effectiveness of patenting?Then we give the floor to Christopher May of the University of Lancaster, who looks at the question of how universities have to deal with the global information society.

This is an attempt at reviving Kneale's version of the description theory of names, which says that a proper name is synonymous with a definite description of the form ‘the individual named so-and-so’. To begin with, I adduce a wide range of observations to show that names and overt definites are alike in all relevant respects. I then turn to Kripke's main objection against Kneale's proposal, and endeavour to refute it. In the remainder of the paper I elaborate on Kneale's (...) analysis, adopting a theory of presupposition proposed by van der Sandt. (shrink)

Henry Sidgwick shared many of the feminist concerns of John Stuart Mill and was an active reformer in the cause of higher education for women, but his feminism has never received the attention it deserves and he has in recent times been criticized for promulgating a masculinist epistemology.

This book provides a theory of the juridification of business ethics. Ethical codes pop up everywhere in the business world and increasingly resemble the code of law. A focus on compliance rather than reflection becomes the norm. Legal perspectives replace ethical perspectives, turning ethicists into lawyers without a law degree. This juridification of business ethics conceals a diminishing trust in ethics, as legal reasoning substitutes philosophical thinking. By appealing to the critical study of law, Bart Jansen advocates for a (...) renewed focus on the ethical side of business. This book shows the importance of a good balance between law and ethics in business and is of great interest to both academics and professionals. (shrink)

This paper consists of two main parts and a coda. In the first part I present the ''binding theory'' of presupposition projection, which is the framework that I adopt in this paper (Section 1.1). I outline the main problems that arise in the interplay between presuppositions and anaphors on the one hand and attitude reports on the other (Section 1.2), and discuss Heim''s theory of presuppositions in attitude contexts (Section 1.3).In the second part of the paper I present my own (...) proposal. To begin with, I define an extension of DRT in which attitude reports can be represented (Sections 2.1–2.2). I then argue that the verb believe triggers a certain presupposition and that, given the binding theory, this presupposition determines the projection behaviour of the verb (Section 2.3). This analysis yields predictions which are incomplete in the sense that they do not fully account for speakers'' intuitions about presuppositions and anaphors in belief contexts. In Section 2.4 I suggest that this is as it should be because we may assume on independent grounds that there is a class of plausibility inferences which complement the predictions of the presupposition theory. Finally, the analysis is extended to the verb want (Section 2.5). (shrink)

Frank Jackson has argued that, given plausible claims about supervenience, descriptive predicates and property identity, there are no irreducibly normative properties. Philosophers who think that there are such properties have made several objections to this argument. In this paper, I argue that all of these objections fail. I conclude that Jackson's argument shows that there are no irreducibly normative properties.

According to the error theory, normative judgements are beliefs that ascribe normative properties, even though such properties do not exist. In this paper, I argue that we cannot believe the error theory, and that this means that there is no reason for us to believe this theory. It may be thought that this is a problem for the error theory, but I argue that it is not. Instead, I argue, our inability to believe the error theory undermines many objections that (...) have been made to this theory. (shrink)

What is property, and why does our species happen to have it? In The Property Species, the economist Bart Wilson explores how we acquire, perceive, and know the custom of property, and why this might be relevant to social scientists, philosophers, and legal scholars for understanding how property works in the twenty-first century.

It appears that in mixed quotations like the following, the quoted expression is used and mentioned at the same time: (1) George says Tony is his ``bestest friend''. Most theories seek to account for this observation by assuming that mixed quotations operate at two levels of content at once. In contradistinction to such two-dimensional theories, we propose that quotation involves just a single level of content. Quotation always produces a change in meaning of the quoted expression, and if the quotation (...) is mixed the shift is, to a first approximation at least, from '...' to ``what x calls '...''', where x is a variable whose value is determined by the context. We argue that quotation is generally context dependent in various ways, and that some of these ways are presuppositional in nature; we present a detailed analysis of the presuppositions in question.

We can understand and act upon the beliefs of other people, even when these conflict with our own beliefs. Children’s development of this ability, known as Theory of Mind, typically happens around age 4. Research using a looking-time paradigm, however, established that toddlers at the age of 15 months old pass a non-verbal false-belief task (Onishi and Baillargeon in Science 308:255–258, 2005). This is well before the age at which children pass any of the verbal false-belief tasks. In this study (...) we present a more complex case of false-belief reasoning with older children. We tested second-order reasoning, probing children’s ability to handle the belief of one person about the belief of another person. We find just the opposite: 7-year-olds pass a verbal false-belief reasoning task, but fail on an equally complex low-verbal task. This finding suggests that language supports explicit reasoning about beliefs, perhaps by facilitating the cognitive system to keep track of beliefs attributed by people to other people. (shrink)

Even though more than half of all citizens in the world are currently able to exercise the right to elect their leaders, many of them choose not to vote. This article considers the role of compulsory voting in order to enhance the democratic values of political participation and equality. Raising turnout considerably, it is an effective instrument to motivate citizens to express their voice in public life, thereby ensuring that their concerns will be heeded. Opponents of compulsory voting, however, argue (...) that it is undesirable because it violates the value of personal liberty and drags uninterested citizens to the polls. This article tries to rebut these arguments and challenge their underlying concept of democracy. As compulsory voting sends the message that every vote matters, it is able to restore rather than harm democracy and its values. (shrink)

The Sublime in Schopenhauer's Philosophy transforms our understanding of Schopenhauer's aesthetics and anthropology. Bart Vandenabeele breaks new ground by providing what is probably the first monograph to be devoted exclusively to Schopenhauer's theory of the sublime. The book focuses on Schopenhauer's conception of the sublime and how it relates to the individual and its attitude towards life. The author explores in unusual depth Schopenhauer's relation to Kant, whose follower and critic he was, and shows how Schopenhauer's aesthetic theory moves (...) beyond Kant's in numerous meaningful ways. Drawing on recent insights in psychology and the philosophy of mind, Vandenabeele seeks ultimately to rework Schopenhauer's theory into a viable form so as to establish the sublime as a distinctive aesthetic category with a broader existential and metaphysical significance.

A colorful history of utilitarianism told through the lives and ideas of Jeremy Bentham, John Stuart Mill, and its other founders In The Happiness Philosophers, Bart Schultz tells the colorful story of the lives and legacies of the founders of utilitarianism—one of the most influential yet misunderstood and maligned philosophies of the past two centuries. Best known for arguing that "it is the greatest happiness of the greatest number that is the measure of right and wrong," utilitarianism was developed (...) by the radical philosophers, critics, and social reformers William Godwin, Jeremy Bentham, John Stuart and Harriet Taylor Mill, and Henry Sidgwick. Together, they had a profound influence on nineteenth-century reforms, in areas ranging from law, politics, and economics to morals, education, and women's rights. Their work transformed life in ways we take for granted today. Bentham even advocated the decriminalization of same-sex acts, decades before the cause was taken up by other activists. As Bertrand Russell wrote about Bentham in the late 1920s, "There can be no doubt that nine-tenths of the people living in England in the latter part of last century were happier than they would have been if he had never lived." Yet in part because of its misleading name and the caricatures popularized by figures as varied as Dickens, Marx, and Foucault, utilitarianism is sometimes still dismissed as cold, calculating, inhuman, and simplistic. By revealing the fascinating human sides of the remarkable pioneers of utilitarianism, The Happiness Philosophers provides a richer understanding and appreciation of their philosophical and political perspectives—one that also helps explain why utilitarianism is experiencing a renaissance today and is again being used to tackle some of the world's most serious problems.

In this article we examine the effectiveness of consent in data protection legislation. We argue that the current legal framework for consent, which has its basis in the idea of autonomous authorisation, does not work in practice. In practice the legal requirements for consent lead to ‘consent desensitisation’, undermining privacy protection and trust in data processing. In particular we argue that stricter legal requirements for giving and obtaining consent as proposed in the European Data protection regulation will further weaken the (...) effectiveness of the consent mechanism. Building on Miller and Wertheimer’s ‘Fair Transaction’ model of consent we will examine alternatives to explicit consent. (shrink)

The legal basis for processing personal data and some other types of Big Data is often the informed consent of the data subject involved. Many data controllers, such as social network sites, offer terms and conditions, privacy policies or similar documents to which a user can consent when registering as a user. There are many issues with such informed consent: people get too many consent requests to read everything, policy documents are often very long and difficult to understand and users (...) feel they do not have a real choice anyway. Furthermore, in the context of Big Data refusing consent may not prevent predicting missing data. Finally, consent is usually asked for when registering, but rarely is consent renewed. As a result, consenting once often implies consent forever. At the same time, given the rapid changes in Big Data and data analysis, consent may easily get outdated. This paper suggests expiry dates for consent, not to settle questions, but to put them on the table as a start for further discussion on this topic. Although such expiry dates may not solve all the issues of informed consent, they may be a useful tool in some situations. (shrink)
