The discovery of CRISPR/cas9 has opened new avenues in gene editing. This system, usually considered as molecular scissors, permits the cutting of the DNA at a targeted site allowing the introduction of new genes or the removal or the modification of existing ones. The genome-editing, involving gene drive or not, is then considered with a strong interest in a variety of fields ranging from agriculture to public health and conservation biology. Given its controversial aspects, it is then no surprise that (...) actors in biodiversity conservation do express conflicting views on this emerging and disruptive technology. The positions are ranging from a request for a moratorium to the will to test and deploy it in strategies aiming at eradicating invasive species of mammals on islands. Reviewing some of its recent developments brings light on the conflicts of interest, the financial support, and lobbying currently occurring in this growing field of biotechnology. While an optimistic view on the use of gene drive for ecosystem conservation was first promoted by several molecular biologists, the risks and uncertainties associated have now led to some reservations. Overall, the eventual use of this novel approach for conservation raises concerns related to the engagement of the public, the communication between scientists, and the public and the risk of a manufactured consent. There are also a series of essential ethical and philosophical questions on the relations we have with Nature that needs to be answered. (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)

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.

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.

Many philosophers argue that the error theory should be rejected because it is incompatible with standard deontic logic and semantics. We argue that such formal objections to the theory fail. Our discussion has two upshots. First, it increases the dialectical weight that must be borne by objections to the error theory that target its content rather than its form. Second, it shows that standard deontic logic and semantics should be revised.

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)

In this article, we discuss the role that ‘true preferences’ can and should play in discussions on the possibility and desirability of paternalist nudges. Critics have claimed that such preferences do not exist, cannot be known reliably by third parties, and cannot justify whether and how to nudge people. In this article, we argue that these objections undermine the extent to which philosophers and laypeople can make sense of autonomy and authenticity. We aim to identify what kinds of preferences can (...) plausibly be labelled ‘true’ and how that impacts discussions on the ethics of paternalist nudging. We analyse what ‘true preferences’ can mean, not for Econs, but for Humans, and argue, more specifically, that some of our existing preferences have special status. In addition, we argue that satisfying them is good for individuals and that nudgers should seek to overcome the epistemic challenges of discovering their content. (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.

There is a well‐known argument against irreducibly normative properties that appeals to the following claim about supervenience: for all possible worlds W and W*, if the instantiation of descriptive properties in W and W* is exactly the same, then the instantiation of normative properties in W and W* is also exactly the same. This claim used to be uncontroversial, but recently several philosophers have challenged it. Do these challenges undermine this argument? I argue that they do not, since the negation (...) of this claim about supervenience has consequences that are much more implausible than the negations of key premises in these challenges. (shrink)

In this article we first clarify the technological possibilities in an Age of Biological Control. Secondly we offer a short overview of some major international statements on reproductive cloning. Since a careful use of terminology will help public policy, we opt for a clarification of the means and purposes of human cloning in a third paragraph. Fourthly, we summarize the main arguments against human reproductive cloning from a bio-ethical point of view. The main objective is however the analysis of the (...) influence of two different theological interpretations of Imago Dei in the cloning debate: stewardship and created co-createdness. We evaluated the dynamic approach from a creational perspective to be the most apt for coping with new biotechnological developments. The authors conclude, however, that also this more dynamic theological approach leads to a radical rejection of reproductive cloning. (shrink)

A survey amongst 602 Flemish secondary school pupils, aged 17-18, shows that a distinction can be made between two different, albeit closely related, dimensions of royalism : the emotional attachment to the king as a person and to the royal family on the one hand, and the political support for the monarchy on the other. Respondents are predominantly indifferent or negative about the monarchy, particularly on the emotional dimension. A multivariate analysis shows that male and non-churchgoing pupils are more negative (...) on both dimensions. Pupils from migrant families are more positive on the emotional dimension. The scores on both dimensions are higher amongst pupils who identify with Belgium rather than with Flanders, who have strong patriotic feelings and who tend towards an authoritarian attitude. The scores are lower amongst pupils with apreference for a regionalist party. The hypothesis that intense royalist feelings coincide with a general attitude of trust in the political authorities was only confirmed with regard to the emotional dimension, while the political support for the monarchy appears to be detached from the trust in the political authorities.

In spite of the fact that people spontaneously presuppose that moral consensus does not exist in today’s world, modern societies tend nevertheless to be characterised by an egalitarian liberal engagement that is sustained by a broadly upheld collective concern: the rejection or neutralisation of any kind of public justification. The failure of this neutralisation is apparent for all to see, however, leading modern societies with problems the existence of which they are forced to deny. The resulting situation thus obliges egalitarian (...) liberal societies to review many of their moral presuppositions. (shrink)

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)

Martin-Löf's constructive type theory forms the basis of this paper. His central notions of category and set, and their relations with Russell's type theories, are discussed. It is shown that addition of an axiom - treating the category of propositions as a set and thereby enabling higher order quantification - leads to inconsistency. This theorem is a variant of Girard's paradox, which is a translation into type theory of Mirimanoff's paradox (concerning the set of all well-founded sets). The occurrence of (...) the contradiction is explained in set theoretical terms. Crucial here is the way a proof-object of an existential proposition is understood. It is shown that also Russell's paradox can be translated into type theory. The type theory extended with the axiom mentioned above contains constructive higher order logic, but even if one only adds constructive second order logic to type theory the contradictions arise.

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)

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)

The reform movement in science is seemingly constructing a new moral economy of science around process and bureaucracy, in which a new scientific etiquette is emerging that prescribes the performance of reformed science as civilised, efficient and objective. Bureaucratic innovations were borne out of the reform movement that seek to prescribe specific research processes, including but not limited to preregistration and registered reports. This moral economy emerges in the form of a bureaucracy and its epistemic uniformity actively suppresses scientific plurality. (...) This paper argues that Eliasian drivers such as distinction, shame and disgust, act to pressure scientists into adopting this new etiquette. Even though the etiquette's appearance is quite new, it can be traced back to existing moral economies of science and their pursuit of efficiency and objectivity. (shrink)

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.

The concept of resistance has always been central to the reception of Hegel's philosophy. The prevalent image of Hegel's system, which continues to influence the scholarship to this day, is that of an absolutist, monist metaphysics which overcomes all resistance, sublating or assimilating all differences into a single organic 'Whole'. For that reason, the reception of Hegel has always been marked by the question of how to resist Hegel: how to think that which remains outside of or other to the (...) totalizing system of dialectics. In recent years the work of scholars such as Catherine Malabou, Slavoj Žižek, Rebecca Comay and Frank Ruda has brought considerable nuance to this debate. A new reading of Hegel has emerged which challenges the idea that there is no place for difference, otherness or resistance in Hegel, both by refusing to reduce Hegel's complex philosophy to a straightforward systematic narrative and by highlighting particular moments within Hegel's philosophy which seem to counteract the traditional understanding of dialectics. This book brings together established and new voices in this field in order to show that the notion of resistance is central to this revaluation of Hegel. (shrink)

Genetically engineered (GE) insects, such as the GE OX513A Aedes aegypti mosquitoes, have been designed to suppress their wild-type populations so as to reduce the transmission of vector-borne diseases in humans. Apart from the ecological and epidemiological uncertainties associated with this approach, such biotechnological approaches may be used by individual governments or the global community of nations to avoid addressing the underlying structural, systemic causes of those infections... We discuss here key ethical questions raised by the use of GE mosquitoes, (...) with the aim of fostering discussion between the public, researchers, policy makers, healthcare organizations, and regulatory agencies at the local, national, and international levels. We affect that goal by outlining a procedural approach to decision-making about the use of the “biotechnology” that goes beyond “community engagement.” The protocol we advocate for entails informed deliberations and decision-making at the community level. It is designed to ensure that the voices of the marginalized and vulnerable groups that would be disproportionately affected by the decision are heard during the community-wide discussions. Moreover, we make the case that the values embedded in the risk assessment should be identified so that the community can make an informed decision about the use of GE insects. In addition, we advocate for the involvement of a variety of actors whose responsibility would be to ensure that the community has the opportunity to make an informed decision based on deliberations about the use of the “biotechnology.”.

We argued that formal objections to the error theory overgeneralize and therefore fail. Christine Tiefensee and Gregory Wheeler deny this. We argue that they are wrong, for two reasons. The first concerns how we should adjudicate conflicts between formal and substantive commitments. The second concerns an overlooked tension between formal objections and non-error-theoretic views. Our discussion shows that the commitments behind formal objections to the error theory, such as the dual schema, should be regarded as much more contentious than is (...) often assumed. (shrink)

To be able to say what practical reasoning is, we first need to say what reasoning is and what the conclusion of a process of reasoning is. I shall do this in sections 1 and 2. We can then make a distinction between practical and theoretical reasoning. There are three main ways to do this, which I shall survey in sections 3 to 5. I shall end by suggesting that there are different kinds of practical reasoning.

New Perspective scholars challenge Protestant interpretations of Paul. It used to be the case, they state, that Protestants assumed that Paul was to Judaism as Luther was to Medieval Catholicism. Both men supposedly reacted against legalistic religions and championed grace-based faiths. However, in 1977, E.P. Sanders wrote Paul and Palestinian Judaism, arguing that Judaism is not a legalistic but a grace-based faith. Assuming that Sanders is correct, New Perspectivists claim that Paul’s and Luther’s theologies and experiences were thus not parallel. (...) Hence, Luther misunderstood Paul. Additionally, New Perspectivists challenge Protestant understandings of ‘justification’. In New Perspective thought, Paul uses the term ‘justification’ primarily to describe how people, particularly Gentiles, join the church Christians without following Jewish ritual laws. ‘Justification’, then, does not describe how people ‘stay in’ the covenant and receive salvation, as Protestants think. However, this article maintains that while New Perspectivists have some knowledge of Paul and Judaism, they are much less knowledgeable regarding Luther, Medieval Catholicism and Luther’s reaction to it. Greater scrutiny of these latter areas reveals large difficulties with New Perspective arguments. In addition, a review of relevant passages from Paul’s letters demonstrates that Protestants have not misunderstood Paul’s use of the term ‘justification’. Many Pauline passages show that when Paul discusses justification he is also thinking about ‘staying in’, not just ‘getting in’ the covenant. (shrink)

Various generalizations of Boolean algebras are being studied in algebraic quantum logic, including orthomodular lattices, orthomodular po-sets, orthoalgebras and effect algebras. This paper contains a systematic study of the structure in and between categories of such algebras. It does so via a combination of totalization (of partially defined operations) and transfer of structure via coreflections.

This article introduces a computational model which illustrates how a population of agents can coordinate a vocabulary for goal oriented behavior through repeated local interactions, called “Action Games”. Using principles of self organization and specific assumptions on their behavior, the agents learn the goals and a vocabulary for them. It is shown that the proposed model can be used to investigate the coordination of vocabularies for goal oriented behavior both in a vertical and in a horizontal transmission scheme. Furthermore, it (...) is shown that in this model shared vocabularies can only be learned from multiple demonstrations consisting of exactly these actions that are strictly required to reach the goal. Keywords: robot imitation; self organization; vocabularies. (shrink)

Without doubt, the year 2001 will remain identified with the terrorist attacks of september 11. To some extent, this goes for the European Union as well. The events of september 11 left an important mark on the European integration process, of which the development of the European arrest warrant is an important illustration. Nevertheless, as for the European Union, the year 2001 was more than a year of anti-terrorism measures. In the second semester of2001, the Belgian government assumed the presidency (...) ofthe European Union. 2001 was also the year in which, only weeks after street violence disruputed the European Council ofGöteborg, a protester was killed in the margin ofthe G7-G8 Summit in Genova. In 2001, the gap between the European Union and the United States got larger for a number of policy fields, including National Missile Defence and the Kyoto Protocol. Yet, in the autumn of2001, both power blocks reconciliated at the WTO Ministerial Conference in Doha, Qatar. In Doha, a new global round of trade negotiations was launched. As in previous years, in 2001, the enlargement process was high on the European agenda. As for the latter, for the first time, ten candidate countries were mentioned by name, making their accession in 2004 a more realistic scenario. The eastern enlargement will radically change the face of the European Union. The Belgian presidency anticipated this impeding metamorphosis and stimulated the adoption of the Laeken Declaration in december 2001. The Declaration laid the foundation for the Convention on the Future of Europe which started on February 28, 2002. The Declaration of Laeken was one of the European highlights of 2001. The low point was the Irish referendum of June 7, 2001, in which a majority of the Irish population rejected the Treaty of Nice. Both events reflect the situation the European Union is faced with today, as they demonstrate the growing tension between the desires of «widening» and «deepening» the European construction. The future willreveal how the European Union went with this growing area of tension. (shrink)

Although this review article is only about one book and about one man, it discloses a whole world, the world of Jerome, saint, scholar and stimulator of ascetism and of the study of the Bible. It is the merit of the book reviewed here to bring interesting insights into this other world, the emerging society of monks who were scholars and ascetic. In that world Jerome is one of the most fascinating patristic scholars. His choice for translating the Hebrew Bible (...) instead of the Greek Bible is one of the utmost examples that from time to time the conceitedness of one man wins. Williams’ book teaches us quite a lot about this man and his conceitedness. At the same time it explains us something about the Christian tradition, how asceticism could bring forth the wealth of libraries and abbeys. (shrink)

We investigate topological properties of subsets S of the real plane, expressed by first-order logic sentences in the language of the reals augmented with a binary relation symbol for S. Two sets are called topologically elementary equivalent if they have the same such first-order topological properties. The contribution of this paper is a natural and effective characterization of topological elementary equivalence of closed semi-algebraic sets.
