Most of the reports on synthetic biology include not only familiar topics like biosafety and biosecurity but also a chapter on ‘ethical concerns’; a variety of diffuse topics that are interrelated in some way or another. This article deals with these ‘ethical concerns’. In particular it addresses issues such as the intrinsic value of life and how to deal with ‘artificial life’, and the fear that synthetic biologists are tampering with nature or playing God. Its aim is to analyse what (...) exactly is the nature of the concerns and what rationale may lie behind them. The analysis concludes that the above-mentioned worries do not give genuine cause for serious concern. In the best possible way they are interpreted as slippery slope arguments, yet arguments of this type need to be handled with care. It is argued that although we are urged to be especially vigilant we do not have sufficiently cogent reasons to assume that synthetic biology will cause such fundamental hazards as to warrant restricting or refraining from research in this field.

ABSTRACT Reiter's default logic is one of the most prominent and well-studied approaches to nonmonotonic reasoning. Its evolution has resulted in diverse variants enjoying many interesting properties. This process however seems to be diverging because it has led to default logics that are difficult to compare due to different formal characterizations—sometimes even dealing with different objects of discourse. This problem is addressed in this paper in two ways. One the one hand, we elaborate on the relationships between different types (...) of default logics and discuss their differences wrt some basic properties. In particular, we show how two recently proposed variants, namely rational and CA-default logic, are related to each other and existing default logics. As an interesting byproduct, we obtain a cumulative counterpart to Lukasiewicz' variant of default logic. The resulting system is insofar surprising since it necessitates to refine the canonical way of assuring cumulativity in default logics. On the other hand, we pursue an integrating approach. We give a translation embedding rational and CA-default logic into a recently developed framework for default logics. This allows us not only to classify these variants, but it moreover provides us with semantical underpinnings that have been lacking so far. (shrink)

Recent studies have shown that deductive reasoning skills are related to mathematical abilities. Nevertheless, so far the links between mathematical abilities and these two forms of deductive inference have not been investigated in a single study. It is also unclear whether these inference forms are related to both basic maths skills and mathematical reasoning, and whether these relationships still hold if the effects of fluid intelligence are controlled. We conducted a study with 87 adult participants. The results showed (...) that transitive reasoning skills were related to performance on a number line task, and conditional inferences were related to arithmetic skills. Additionally, both types of deductive inference were related to mathematical reasoning skills, although transitive and conditional reasoning ability were unrelated. Our results also highlighted the important role that ordering abilities play in mathematical reasoning, extending findings regarding the role of ordering abilities in basic maths skills. These results have implications for the theories of mathematical and deductive reasoning, and they could inspire the development of novel educational interventions. (shrink)

Both the production of knowledge and the product, knowledge itself, are social phenomena. This generally accepted fact is generally thought to require relativism, scepticism, and Kuhnian incommensurability, as well as casting serious doubt on the potential of our cognitive traditions to provide us with objective knowledge about an objective world. This thesis exposes and critiques the presuppositions about the nature of reasoning and objectivity which underlie these fears. Combining a Nietzschean, perspectivist account of objectivity with a conception of (...) class='Hi'>reasoning drawn from Lockean epistemology and pedagogy, I build a new account of cognitive optimality, dubbed 'Linkmaking'. The phrase deliberately encompasses several meanings. We 'make links' by noticing connections between objects in the world, by linking ideas together to form a theory or a curriculum; by forming social connections, and by developing interdisciplinary practices. I defend the view that we cannot fully address any of these kinds of Link without reference to all of the others. I further show that out best means to critically assess our cognitive groups is to evaluate the extent to which those groups encourage Linkmaking practices. The major potential challenge to Linkmaking is Kuhnian incommensurability. Having demonstrated the flaws inherent in Kuhn's account, this thesis defends the weaker, Doppeltian form of incommensurability, which grants us insight into the genuine problems which can occur in interdisciplinary research. We then see that the Strong Programme in the sociology of knowledge, inspired by the strong, relativistic version of the Kuhnian incommensurability thesis, has held sway among sociologists because they do not generally study interdisciplinary practices, which highlight scientists' objectivity. Furthermore, social scientists who accept Kuhnian constructivism doubt their own potential for objectivity, presuming the presence of strong incommensurability where there is none. Undertaking Linkmaking practices both cures this illusion, and improves the cognitive optimality of the group. (shrink)

The primary purpose of this cross sectional study was to empirically test the notion that retail pharmacists' moral reasoning scores (using Rest's Defining Issues Test) relate to their patient care performance scores (using the Behavioral Pharmaceutical Care Scale). Presently, retail pharmacy organizations are experiencing a paradigm shift from a prescription dispensing emphasis to a patient-centered one. The present investigation examined the influence of moral reasoning, within the situational context of workload pressures and perceived normative beliefs of significant others, (...) on retail pharmacists' self-report patient care performance scores.A secondary goal was to explore the relationship between moral reasoning and retail pharmacists' propensity to exaggerate depictions of their true behavior (using a short-form Marlowe-Crowne Social Desirability Scale).

Although Jürgen Habermas has a strong argument to link reason and philosophy, he also thinks that religion has a legitimate place in the (rational) public sphere. The question, though, is: what does this legitimate place entail? Is the power of religious language due to the fact that modern culture is not sufficiently secularized, that is, not yet sufficiently philosophic? Or is the power of religious language due to the fact that it successfully articulates certain widely shared moral (and substantive) intuitions? (...) In addressing these questions, this contribution has four parts. In the first section the issue of Critical Theory and religion will be briefly examined. The point here is that where religion (like aesthetics) plays a more central role amongst the thinkers of the first movement of Critical Theory (theorists such as Horkheimer, Adorno, Marcuse, and Benjamin), this is not the case with Habermas (the leading exponent of the second movement). In the second section, this aspect is further explored by reconstructing Habermas’s intellectual project (with its religious implications) in six steps. Finally (in the third and fourth sections) some critical remarks (inter-paradigmatic and extra-paradigmatic) will be made on Habermas’s view of religion. (shrink)

Reasoning Practically deals with a classical philosophical topic, the link between thought and action--how we think about what we do or ought to do, and how we move from thinking to doing. The essays by such renowned contributors as Donald Davidson, Barry Stroud, Cass R. Sunstein, Seyla Benhabib, and Gerald Dworkin, cover a range of issues raised when we link reason and practice. This collection connects state-of-the-art philosophical work with concrete issues in social life and political practice, making it (...) of interest not only to philosophers, but to political theorists, legal scholars, and any researcher interested in the practical application of reason.

Legal and moral reasoning share much methodology, and they address similar problems. This volume charts two shared problems: the relation between theory, principles and particular judgments; and the role of facts and factual assertions in normative settings. The relation between 'theory' and 'practice' and between 'principle' and 'particular judgment' has become the subject of much debate in moral philosophy. In the ongoing debate, some moral philosophers refer to legal philosophy for a support of their views on the primacy of (...) 'practice' over 'theory'. According to them, legal philosophy should have a more balanced view in that relation. In the contributions to Part One this claim is critically analysed. The role of the facts is underestimated in discussions on legal reasoning and legal theory, as well as moral reasoning and ethical theory. Factual statements enter into moral and legal discussions not only because they link the conclusion with a rule. They also play a role as background assumptions in supporting a theory. Its focus on the role of facts in normative reasoning makes this book of special interest to scholars of legal and moral argumentation. (shrink)

Reasoning with the maximally consistent subsets of the premises is a well-known approach for handling contradictory information. In this paper we consider several variations of this kind of reasoning, for each one we introduce two complementary computational methods that are based on logical argumentation theory. The difference between the two approaches is in their ways of making consequences: one approach is of a declarative nature and is related to Dung-style semantics for abstract argumentation, while the other approach has (...) a more proof-theoretical flavor, extending Gentzen-style sequent calculi. The outcome of this work is a new perspective on reasoning with MCS, which shows a strong link between the latter and argumentation systems, and which can be generalized to some related formalisms. As a by-product of this we obtain soundness and completeness results for the dynamic proof systems with respect to several of Dung’s semantics. In a broader context, we believe that this work helps to better understand and evaluate the role of logic-based instantiations of argumentation frameworks. (shrink)

The problem of cortical integration is described and various proposed solutions, including grandmother cells, cell assemblies, feed-forward structures, RAAM and synchronization, are reviewed. One method, involving complex attractors, that has received little attention in the literature, is explained and developed. I call this binding through annexation. A simulation study is then presented which suggests ways in which complex attractors could underlie our capacity to reason. The paper ends with a discussion of the efficiency and biological plausibility of the proposals as (...) integration mechanisms for different regions and functions of the brain. (shrink)

Trust is so intimately linked with faith that sometimes trust needs faith to unfold in a relationship. I argue that the role of this faith element in trust is to elevate the status of the one in which we trust so as to emphasize the equal dignity of all the participants in the relationship of trust. Against views that focus on a «rational» trust based on an exaggerated emphasis on the capacity of self-trust as a point of departure for (...) the trust in others, the essay develops toward the depiction of a kind of trust that is rooted in faith and still maintains a «reasonable» character. By way of discussing the implications of Thomas Hobbes’s reflections on covenants and contracts, and Annette Baier’s critique of what she sees as the Hobbesian «fixation» on contracts, I argue toward the identification of what I call a «covenantal trust» in contemporary political ontology.

Covering an important theme in Humean studies, this book focuses on Hume's hugely influential attempt in book three of his _Treatise of Human Nature _to derive the conclusion that morality is a matter of feeling, not reason, from its link with action. Claiming that Hume's argument contains a fundamental contradiction that has gone unnoticed in modern debate, this fascinating volume contains a refreshing combination of historical-scholarly work and contemporary analysis that seeks to expose this contradiction and therefore provide a significant (...) contribution to current scholarship in the area. Sophie Botros begins by pointing out that a contradiction concerning whether reason can influence action, or is wholly powerless, occurs in the intermediary premiss. She then moves on to draw out the consequences for recent meta-ethics of the failure to acknowledge this contradiction. Finally, highlighting the root of the argument's power in an article of naturalistic dogma, she suggests how it may be possible to restore to our moral concepts their traditional and integral link with both truth and motivation. A significant and thought-provoking addition to this popular field of study, _Hume, Reason and Morality_ is undoubtedly an important resource for moral philosophers interested in meta-ethics and practical reason, as well as Humean scholars.

This article provides a theoretical and doctrinal explanation of how the but-for test links gains to the wrong that produced them. Gain-based damages cases focus on the gain resulting from the defendant’s tortious behaviour. In these cases, the contrastive aspect of the but-for test, requiring the factfinder to consider the hypothetical result that would have occurred had the right thing happened instead of the defendant’s wrongdoing, is not confined to the question of reasonability, as it is in negligence cases. Rather, (...) in gain-based damages cases, the factfinder faces the open-ended normative task of determining the hypothetically appropriate scenario that contrasts with the wrongdoing that happened in reality. For this reason, in gain-based damages cases, the normative sensitivity of the but-for test is revealed in full. The article explains how this sensitivity influences the result of the but-for test expressing the amount of gain causally attributed to the defendant’s wrongdoing. (shrink)

This paper is to critically examines Pollock’s critical-link semantics with variable degrees of justification. Some possibly counterintuitive consequences of Pollock’s definition of degrees of justification are identified and a modified definition is proposed which avoids these consequences. Then the new solution is applied to the case of so-called presumptive defeat. A second contribution of the paper is to show how the modified semantics can be applied to the ASPIC+ framework: first the ASPIC+ framework is modified to allow for variable degrees (...) of justification and then the modified way to compute these degrees is applied in a new notion of an argument graph.

Reasons are considerations that figure in sound reasoning. This is considered by many philosophers to be little more than a platitude. I argue that it actually has surprising and far-reaching metanormative implications. The view that reasons are linked to sound reasoning seems platitudinous only because we tend to assume that soundness is a normative property, in which case the view merely relates one normative phenomenon (reasons) to another (soundness). I argue that soundness is also a descriptive phenomenon, (...) one we can pick out with purely descriptive terms, and that the connection between normative reasons and sound reasoning therefore provides the basis for a reductive account of reasons. Like all proposed reductions, this one must confront some version of G. E. Moore’s open question argument. I argue that a reductive view rooted in the idea that reasons figure in sound reasoning is well-equipped to meet the open question challenge head on. (shrink)

Interacting with others frequently involves making common-sense inferences linking context, background knowledge, and beliefs to utterances in the dialogue. As language users we are generally good at this kind of dialogical reasoning, and might not even be aware we are involved in it while we engage in a conversation. However, sometimes it is not obvious how a particular contribution should be interpreted in terms of the underpinning assumptions warranting an inference. In dialogue involving participants who demonstrate atypical linguistic behavior, (...) such as patients with schizophrenia, the effects may be even more marked. (shrink)

An impressive characteristic of Dudley Shapere's studies in the philosophy of the sciences has been his dogged reasonableness. He sorts things out, with logical care and mastery of the materials, and with an epistemological curiosity for the historical happenings which is both critical and respectful. Science changes, and the philosopher had better not link philosophical standards too tightly to either the latest orthodox or the provocative up start in scientific fashions; and yet, as critic, the philosopher must not only master (...) the sciences but also explicate their meanings, not those of a cognitive never-never land. Neither dreamer nor pedant, Professor Shapere has been able to practice the modern empiricist's exercises with the sober and stimulat ing results shown in this volume: he sees that he can be faithful to philosoph ical analysis, engage in the boldest 'rational reconstruction' of theories and experimental measurements, and faithful too, empirically faithful we may say, to both the direct super-highways and the winding pathways of conceptual evolutions and metaphysical revolutions. Not least, Shapere listens! To Einstein and Calileo of course, but to the workings of the engineers and the scientific apprentices too, and to the various philosophers, now and of old, who have also worked to make sense of what has been learned and how that has happened and where we might go wrong.

A longstanding question is the extent to which "reasonable doubt" may be expressed simply in terms of a threshold degree of belief. In this context, we examine the extent to which learning about possible alternatives may alter one's beliefs about a target hypothesis, even when no new "evidence" linking them to the hypothesis is acquired. Imagine the following scenario: a crime has been committed and Alice, the police's main suspect has been brought to trial. There are several pieces of evidence (...) that raise the probability that Alice committed the crime. Her attorney's defense strategy is not to challenge this evidence, but instead to provide personal details about Alice's neighbour, Jane. While Jane is one of many people the police spoke to, they saw no reason to investigate her further. You now learn that Jane, too, had access to the shed where the murder weapon was stored, just like Alice. To what extent should this alter your beliefs about Alice's guilt? In this paper, we provide a formal description of the problem and a solution indicating circumstances under which learning about Jane will more or less impact beliefs about Alice. (shrink)

Machine learning and nonmonotonic reasoning are closely related, both concerned with making plausible as well as certain inferences based on available data. In this document a brief overview of different approaches to nonmonotonic reasoning is presented, and it is shown how the concept of argumentation systems arises.

The document aims to highlight the links between nonmonotonic reasoning, argumentation and machine learning and as a result propose some potentially useful (...) directions for new research.

The objective of the consistent-amplitude approach to quantum theory has been to justify the mathematical formalism on the basis of three main assumptions: the first defines the subject matter, the second introduces amplitudes as the tools for quantitative reasoning, and the third is an interpretative rule that provides the link to the prediction of experimental outcomes. In this work we introduce a natural and compelling fourth assumption: if there is no reason to prefer one region of the configuration space (...) over another, then they should be “weighted” equally. This is the last ingredient necessary to introduce a unique inner product in the linear space of wave functions. Thus, a form of the principle of insufficient reason is implicit in the Hilbert inner product. Armed with the inner product we obtain two results. First, we elaborate on an earlier proof of the Born probability rule. The implicit appeal to insufficient reason shows that quantum probabilities are not more objective than classical probabilities. Previously we had argued that the consistent manipulation of amplitudes leads to a linear time evolution; our second result is that time evolution must also be unitary. The argument is straightforward and hinges on the conservation of entropy. The only subtlety consists of defining the correct entropy; it is the array entropy, not von Neumann's. After unitary evolution has been established we proceed to introduce the useful notion of observables and we explore how von Neumann's entropy can be linked to Shannon's information theory. Finally, we discuss how various connections among the postulates of quantum theory are made explicit within this approach. (shrink)

While differing widely in other respects, both neo-Humean and neo-Kantian approaches to normativity embrace an internalist thesis linking reasons for acting to potential motivation. This thesis pushes in different directions depending on the underlying view of the powers of practical reason, but either way it sets the stage for an attack on realist attempts to ground reasons directly in facts about value. How can reasons that are not somehow grounded in motivational features of the agent nonetheless count as reasons for (...) that particular agent, having genuine normative force for her? Won't any realist, externalist view threaten to alienate the individual from the reasons that obtain for her, particularly if she fails (even after rational deliberation) to care about the values that are supposed to ground them? I argue that such objections can successfully be answered, and that externalist views of reasons need not be plagued with normative alienation. Focusing largely on a recent debate between Williams and McDowell over the nature of normative reasons, I show that a value-based externalist theory, when properly conceived, can account for the normative relevance of reasons to the particular agents for whom they obtain. Moreover, Williams's own sophisticated neo-Humeanism turns out to be vulnerable to parallel charges of normative alienation, which it cannot escape without compromising the very psychologistic orientation that has been its chief attraction. Realist externalism about reasons turns out to be a more viable and attractive alternative to both neo-Humeanism and neo-Kantianism than many currently take it to be. (shrink)

Controversy has reigned for some time over the biological connection between DNA methylation and cancer. For this reason, the methylation mechanism responsible for increased cancer risk has received greater attention in recent years. Tumor suppressor genes are often hypermethylated resulting in gene silencing. Although some have questioned this interpretation of the link between methylation and cancer, it appears that both hypermethylation and hypomethylation events can create epigenetic changes that can contribute to cancer development. Recent studies have shown that the methyltransferases (...) DNMT1 and DNMT3b cooperatively maintain DNA methylation and gene silencing in human cancer cells. Disruption of the human DNMT3b only slightly reduces the overall global DNA methylation; however, demethylation was markedly potentiated when both DNMT1 and DNMT3b were simultaneously deleted. The results to these experiments provide compelling evidence towards a role for DNA methylation in cancer. This review discusses the current understanding of cancer‐epigenetic information and highlights recent studies that connect the methylation machinery and chromatin remodelling with cancer susceptibility.

In lieu of an abstract, here is a brief excerpt of the content:Reasons CountJohn Z. Sadler (bio)Keywordscriminality, mental disorder, responsibilityAs a fourth-year psychiatry resident many years ago, I encountered a patient on the psychiatric emergency service whom I have never forgotten, because my experience with him jelled a distinction about the importance of explaining violence. Brought in involuntarily by the police for being “dangerous,” he was a fearsome visage: six feet four, shaven head, angular jaw, the triangular build of an (...) athlete, a history of paranoid schizophrenia and violence. I’ll call him Mr. Big. His court order papers explained that he had threatened to kill his brother-in-law.Mr. Big’s story, in brief, was that he was a veteran on disability, and that he had purchased, some years ago, a small home using his wits and savings from his pension. Although he admitted that he could be, and had been, violent off his medications, he explained that he had been taking his medicines reliably for two years and had never had any trouble over that period—until now. His brother-in-law, according to Mr. Big, had moved in and appropriated his home while the patient was away on a trip to see a friend, and now refused to leave, to the chagrin of both the patient and his sister. Mr. Big had threatened to kill the brother-in-law in indignation with the in-law’s behavior. The brother-in-law never called or appeared. The sister, it turns out, corroborated the story, and after an examination revealed only minimal idiosyncrasies of thought and affect, the patient was referred for legal counseling, released, and the family was warned. We all hoped that justice could be found peacefully.Wilson and Adshead emphasize in their thoughtful discussion of violence and psychiatric symptoms that the explanation for the violent act is crucial to assessing its pertinence to mental disorder. What was elegant in Mr. Big’s case was that the motivation for threats of violence was proximate, morally comprehensible, corroborated by at least one other, insightful, and most of all, clear-cut. Although these features for distinguishing violence due to normative motivation versus violence due to mental disorder are addressed by Wilson and Adshead, they would agree that, unfortunately, these tools of proximity, comprehensibility, ordinariness of motivation, insight, and corroboration are often absent, unobtainable, or inadequate.But these considerations are helpful in ruling out violence as symptom, which is the lesson Mr. Big taught me—reasons count. Wilson and Adshead go on to critically consider the features that may be positive identifications for violence as symptom. With “deplorability,” they identify a feature of the violence that exceeds what I have termed “normative motivation,” which defies our empathic ability to understand the perpetrator’s point of view. However, deplorable events are perpetrated by soldiers and police in their socially approved work, so even deplorability has limits in its utility. Indeed, social psychologists’ research has shown, as Susan Fiske and colleagues put it, “Virtually anyone can be aggressive if sufficiently [End Page 73] provoked, stressed, disgruntled, or hot” (Fiske et al. 2004, 1482). Also, like “normative” motivation, deplorability is culture—and politically—relative, another limit to its utility.Even with complex causality, the INUS approach of Mackie’s offers a way to link symptoms to a more complex causal network while admitting that the social components of the causal network may exhibit particular moral and pragmatic interests. For medicine, the INUS approach is sensible and coherent with biomedicine’s intellectual culture of multifactorial causation of disease. However, criminal culpability in law is usually a dichotomous decision; any taint of choice links the offender to the whole culpability package (Sadler 2002).The conclusion one is left with is that no failsafe tools permit us to distinguish violence provoked by mental disorder versus normatively motivated violence. I tend to agree that, for some cases, we will never be able to broker the distinction between disordered violence versus nondisordered violence. My pessimism is based on the technical limitations of parsing mental life retrospectively in a way that will always allow for the kind of clear-cut distinction described in the case of Mr. Big (Sadler 2002). That is, how, after the... (shrink)

In The moral problem (1994), Michael Smith tries to link three conflicting theories that alone are intuitively plausible, nevertheless, they do not seem to work well together. The first proposes that moral judgments are in fact beliefs about objective matters. The second states the concept of “practicality requirement”. The third is a humean belief-desire psychology, i.e. if a moral judgment is sufficient to explain actions, then it must involve a desire. If that is the case, it cannot be simply a (...) belief. For Smith, any attempt to solve the moral problem must find a way to hold all three doctrines. I will argue that his solution rests on two false assumptions. The first, a rationalist one which supports that what we have reason to do is what we would desire to do if we were fully rational. The second is the internalist thesis about moral motivation according to which a person who believes she is morally required to do something is either necessarily motivated to do it or she is practically irrational. I will base my critics on four objections raised by Copp, Miller, Shafer-Landau, Brink and Sayre-McCord. (shrink)

This distinctive collection of original articles features contributions from many of the leading scholars of ancient Greek philosophy. They explore the concept of reason and the method of analysis and the central role they play in the philosophies of Socrates, Plato, and Aristotle. They engage with salient themes in metaphysics, epistemology, ethics, and political theory, as well as tracing links between each thinker’s ideas on selected topics. The volume contains analyses of Plato’s Socrates, focusing on his views of moral psychology, (...) the obligation to obey the law, the foundations of politics, justice and retribution, and Socratic virtue. On Plato’s Republic, the discussions cover the relationship between politics and philosophy, the primacy of reason over the soul’s non-rational capacities, the analogy of the city and the soul, and our responsibility for choosing how we live our own lives. The anthology also probes Plato’s analysis of logos which underlies his philosophy including the theory of forms. A quartet of reflections explores Aristotelian themes including the connections between knowledge and belief, the nature of essence and function, and his theories of virtue and grace. The volume concludes with an insightful intellectual memoir by David Keyt which charts the rise of analytic classical scholarship in the past century and along the way provides entertaining anecdotes involving major figures in modern academic philosophy. Blending academic authority with creative flair and demonstrating the continuing interest of ancient Greek philosophy, this book will be a valuable addition to the libraries of all those studying and researching the origins of Western philosophy.

ABSTRACTAdults use a variety of strategies to reason about fraction magnitudes, and this variability is adaptive. In two studies, we examined the relationships between mathematics anxiety, working memory, strategy variability and performance on two fraction tasks: fraction magnitude comparison and estimation. Adults with higher mathematics anxiety had lower accuracy on the comparison task and greater percentage absolute error on the estimation task. Unexpectedly, mathematics anxiety was not related to variable strategy use. However, variable strategy use was linked to more (...) accurate magnitude comparisons, especially among adults with lower working memory performance or those who use mathematics less frequently, as well as lower PAE on the estimation task. These findings shed light on the role of strategy variability in fraction problem solving and demonstrate a link between mathematics anxiety and fraction magnitude reasoning, a key predictor of general mathematics achievement.

In this essay, I focus on Norberto Bobbio’s reflections on human rights. Firstly, I seek to establish his underlying conception of philosophy: although it is impossible to spell out the philosophical foundations of human rights, this does not imply that philosophical thought, in the sense of critical reason, cannot make a useful contribution and provide valuable arguments in support of human rights. Secondly, I examine the related issue of the justification of human rights and assess his theory on the basis (...) of its own conception of a possible foundation. The way we answer the question of coherence also clarifies (a) what model of civil association is compatible with such a foundation, i.e. with such a worldview; (b) what model is absolutely incompatible with it; and finally (c) what intermediate solutions are there, if there are any. I argue that the communitarian variants of the conception of rights are distortions: collective or cultural rights, i.e. rights of a community towards which all of its members have duties, appearing alongside individual rights, trump individual rights, i.e. the rights linked to personhood that once constituted the most effective legal and political means for emancipating the individual from the power of the community. I therefore consider the “Copernican Revolution” of individualism and its consequences in Bobbio’s thought. As the example of personal freedom shows, where rights are ascribed principally to groups or communities rather than to individuals, we have good reason to fear that rights will turn out to be merely the privilege of the few. Once we follow this line of though in Bobbio, the ecumenical openness to alternative approaches and the argument from “the consensus of the people” yield to a clearly universalistic perspective that derives from the Enlightenment and can be interpreted as the product of the specifically modern version of natural law theory.

This research examines the moderating role of regret aversion in reason-based choice. Earlier research has shown that regret aversion and reason-based choice effects are linked through a common emphasis on decision justification, and that a simple manipulation of regret salience can eliminate the decoy effect, a well-known reason-based choice effect. We show here that the effect of regret salience varies in theory-relevant ways from one reason-based choice effect to another. For effects such as the select/reject and decoy effect, both (...) of which were independently judged to be unreasonable bases for deciding, regret salience eliminated the effect. For the most-important attribute effect that is judged to be normatively acceptable, however, regret salience amplified the effect. Anticipated self-blame regret and perceived decision justifiability consistently predicted preferences and thus offer a parsimonious account of both attenuation and amplification of these reason-based choice effects.

The main purpose of the paper is to contribute to reconstructing the kind of normativity underlying Rawls’s notion of public reason and of the reasonable. The implicit target is the somewhat popular view according to which the transition from the framework of A Theory of Justice to that of Political Liberalism would entail a loss of normativity. On the contrary, the related ideas of public reason and the reasonable are argued to presuppose a notion of normativity – linked with (...) judgment – far more consistent with the premise of the fact of pluralism. After reconstructing Rawls’s notion of public reason, the two following problems are addressed: the problem of determining when allegedly shared truths, the building stones of public reason, are really such and, second, the problem of what it means for one reason to follow or proceed from a shared basis. In the context of such discussion three distinct meanings of the term ‘reasonable’ are identified, and the normatively more demanding one – the notion of some thesis or proposal being not just reasonable, but comparatively ‘more reasonable’ than another – is found to require that the reasonable be understood as the exemplary and, consequently, that we find ways to translate the Kantian doctrine of the exemplary yet universalist validity of aesthetic judgments into a non-aesthetic vocabulary.

Recent work linking feminist epistemology with social epistemology draws attention to the role of status and power in understanding knowledge and reasoning in social context. I argue that considerations of social justice require better understandings of two particular components of reasoning and social context: abstraction—who gets to abstract, how, and why? the individual-social distinction—how do particular understandings of this distinction serve to minimize or elucidate the role of status and power?

We propose a rudimentary formal framework for reasoning about recursion equations over inductively generated data. Our formalism admits all equational programs , and yet singles out none. While being simple, this framework has numerous extensions and applications. Here we lay out the basic concepts and definitions; show that the deductive power of our formalism is similar to that of Peano's Arithmetic; prove a strong normalization theorem; and exhibit a mapping from natural deduction derivations to an applied λ -calculus, à (...) la Curry–Howard, which provides a transparent proof of Gödel's result that the provably recursive functions of PA are definable by primitive recursion in finite types. Also of interest is the extent, uncommon among similar constructions, to which our mapping is oblivious to first order terms, including first order quantification and equality. Additional applications and extensions of the method will be presented in sequel papers. In particular, the methodology introduced here lends itself to systematic links between natural sub-formalisms and computational complexity classes. Since these sub-formalisms are largely transparent, allowing one to reason formally in the full system while leaving to automatic software tools the task of verifying that restrictions are complied with, the framework is particularly attractive for the development of Feasible Mathematics.

Philosophy matters. This is the message of this highly original inquiry into the relationship between science and religion. It is only when we examine the intellectual presuppositions on which science and religion are based, with regard to such fundamentals as truth, objectivity, and realism, that we perceive the link between these two enterprises which are essential to any characterization of man. The book offers a lucid and enlightening account of the main movements in the philosophy of science in the twentieth (...) century, and then proceeds to demonstrate their consequences for philosophy of religion. After examining the wide and all-pervasive influence of positivism, and its offspring relativism, in both science and theology, he suggests that the attempt to provide an alternative, made by Karl Popper, offers the most satisfactory way forward in man’s twofold enquiry in terms of his relationship with God and with the world.

continent. 1.4 (2011): 242—252. Introduction The following two works were produced by visual artist Jonas Staal and writer Vincent W.J. van Gerven Oei during a visit as artists in residence at The Bag Factory, Johannesburg, South Africa during the summer of 2010. Both works were produced in situ and comprised in both cases a public intervention conceived by Staal and a textual work conceived by Van Gerven Oei. It was their aim, in both cases, to produce complementary works that could (...) be read “through each other,” in which the movement of artistic construction would be imitated by textual deconstruction and vice versa. Both works deal with the way in which capital, apartheid, and monumentality are interwoven in South-African society. The Missing Link addresses a monument for democracy, erected on the premises of a private corporation running both an amusement park and the Apartheid Museum franchise. The textual intervention accompanying this public intervention investigates the limits of the inclusiveness of the anti-discrimination section in the South-African constitution, itself a monumental work of democracy. The Monument for the Distribution of Wealth deals with the history and eventual dissolution of a monumental square, commemorating the Soweto Uprising, in one of the poorest townships of Johannesburg. The history accompanying this public dismemberment of memory is equally fragmented, which is expressed by the many voices recounting uncertain and perhaps even irrelevant “facts” about the genius loci, the way in which the memorial space has actually entered into the memory of the inhabitants surrounding it. Next to their individual practices, Staal and Van Gerven Oei have worked together on a number of projects ever since 2007, including several art residencies. Their work involves an investigation of the different interfaces between art, politics, and public space in media ranging from theater and public interventions, to video installations and (co-authored) textual works. The Missing Link Missing Link (1) Missing Link (2) Missing Link (3) Intervention on the monument entitled The Seven Pillars of the Constitution , part of the Apartheid Museum in Johannesburg, South Africa. The Seven Pillars represent the constitutional values propagated in South Africa since the abolition of the apartheid regime. The monument and museum were built by the Gold Reef Resorts corporation, which is also responsible for the theme park and casino next to it. By placing the word “capitalism” on the wall surrounding the museum, the capitalist system and the constant social divisions that it implies are interpreted as sophistic continuations of apartheid politics. Through the capitalist system, apartheid is still operational within South African society. Whereas during the apartheid regime, the separation clearly ran along race divisions, in the current, “democratic” system, the same actual separation is sustained without it being an explicit element of the foundations of the country, i.e. the constitution. This intervention foregrounds the constant role of capitalism is both periods. At the same time the intervention acknowledges that contemporary Western artisthood is a mirror of the privileges that are offered by the capitalist system, and the type of artist that it produces. The intervention initiates a critical discourse concerning the capitalist system situated within the disaster of capitalism itself, in other words: through the desire to break with the presumption that art would be able to operate outside the capitalist system and to confirm that art—and the artist himself—is in fact modeled on this system. The public intervention by Staal was supplemented by a textual intervention by Van Gerven Oei: a proposition to alter the seventeenth amendment of the South African constitution. Even though the anti-discrimination legislation in South-Africa is one of the most stringent and inclusive in the world, one factor—wealth—remains outside its scope, thus continuing the schisms along racial lines produced during the apartheid regime: §9.3. The state may not unfairly discriminate directly or indirectly against anyone on one or more grounds, including race, gender, sex, pregnancy, marital status, ethnic or social origin, colour, sexual orientation, age, disability, religion, conscience, belief, culture, language, birth, and wealth. Monument for the Distribution of Wealth Intervention concerning the June 16 Memorial Acre in Central Western Jabavu, one of the poorest townships of Johannesburg. The monument comprises a park on which different are placed recalling an important protest the black population against the former apartheid regime. In 1976, from a school adjacent to the park, they started a massive protest against the introduction of Afrikaans in the school curriculum. The police reacted violently, and shot several hundreds of students. The construction of the June 16 Memorial Acre was started in 2005, and from the start was the paragon of corruption. Coordinated by local politicians, some family members of the protest leader from 1976 gained control of the realization of the monument, outside the regulation through external institutions. The available budget of 41 million rand (at that time well over 5 million euro) was largely embezzled. In the meantime, the monument has become fully dilapidated and defaced. The park has become overgrown with weeds and covered in a layer of dirt, and the local population is slowly plundering the square to use the material for the construction and decoration of their own houses. The Monument for the Distribution of Wealth develops the dynamics already existent around the June 16 Memorial Acre. Without obtaining official permission in advance, several local inhabitants were hired to break down the monument, sort the materials, and offer it to the neighborhood. Thus, the redistribution of wealth after the fall of the apartheid regime is finally taking place, albeit from the mere remains of the capital that was once invested in the community. The words “monument” and “for free” are spray-painted on the stacks of material, both in English and Zulu, as these are locally the most common languages. Van Gerven Oei supplemented Staal’s public intervention with an account of the history of the monument based on a series of interviews. The account clarifies how the different interests within the protest 1976 are reflected in the exceeding decay of the park, and how in the end those interests were represented by the June 16 Memorial Acre. Monument for the Distribution of Wealth 1: Removing stones Monument for the Distribution of Wealth 3: Pulling down statues Monument for the Distribution of Wealth 4: Offering the material Monument for the Distribution of Wealth 5: Offering the material Monument for the Distribution of Wealth 6 The next day A Fragmentary History of the Monument for the Distribution of Wealth, Formerly Known as the June 16 Memorial Acre in Central Western Jabavu, Soweto Vincent W.J. van Gerven Oei The following text, based on interviews and online research aims to provide parts of a history of the park in front of Morris Isaacson High School in Central Western Jabavu, Soweto. The idea for the transformation of the park into a memorial site has its source in the events of June 16, 1976: the start of the the student uprising in Soweto. The development of the park was started in the early 1980s, and the actual transformation into a memorial site, the June 16 Memorial Acre, was initiated in 2005. Over the last few years, several monumental additions have been made to the park: A marble monument with three pillars was revealed on June 16, 2006. A sculpture of a book and several billboards on June 16, 2008. A sculpture of student leader Tsietsi Mashinini on June 16, 2010. The park was transformed into the Monument for the Distribution of Wealth on August 3, 2010. According to the entry “Youth Struggle” on the website South African History Online, the Bantu Education Act was introduced in 1953 . In 1954 , Dr Verwoerd, Minister of Native Affairs, stated: “What is the use of teaching the Bantu child mathematics when it cannot use it in practice? That is quite absurd.” According to the entry “Soweto uprising” on Wikipedia, the Afrikaans Medium Decree was issued in 1974 , forcing all black schools to use Afrikaans and English in a 50-50 mix as languages of instruction. The Regional Director of Bantu Education (Northern Transvaal Region), J.G. Erasmus, told Circuit Inspectors and Principals of Schools that from January 1, 1975 , Afrikaans had to be used for mathematics, arithmetic, and social studies from standard five (7th grade). English would be the medium for general science and practical subjects. Indigenous languages would be used for religion instruction, music, and physical culture. According the entry “Soweto uprising” on Wikipedia, on April 30, 1976 , students from the Orlando West Junior School in Soweto went on strike, refusing to go to school. Their example was followed by other schools in Soweto. A student from Morris Isaacson High School, Toboho “Tsietsi” Mashinini, proposed a meeting on June 13, 1976 to discuss further action. According to Weizmann Hamilton’s article “The Soweto Uprising 1976,” which appeared in the September 1986 edition of Inqaba Ya Basebenzi (Fortress of the Revolution), on June 13, 1976 , the South African Students’ Movement called a meeting at the Donaldson Community Center in Orlando. 300-400 Students representing 55 schools decided to hold a mass demonstration on June 16. According to Brian Mokhele, member of the Joint Community Safety Forum, Dr Edelstein was the first victim of the Soweto uprising and killed the day before the march on June 15, 1976 . Edelstein was an administrator at the pass office in Jabavu and gave golf courses to the local community. Edelstein was put in a garbage bin and pierced by pickaxes. The garbage bin was left at the very spot of the murder for many years. A few years ago, a child was beheaded at the same spot, and the basketball court next to it has been abandoned since. According to Marcus Neustetter, founder of the Trinity Session, this story is untrue. According the entry “Soweto uprising” on Wikipedia, on June 16 , Tsietsi Mashinini led students from Morris Isaacson High School to join up with others who walked from Naledi High School. A crowd of between 3,000 and 10,000 eventually ended up near Orlando High School. According to Raymond Marlowe, a local photographer, Tsietsi Mashinini was heading the march. According to the entry “Hector Pieterson” on Wikipedia, Dr Edelstein died on June 16, 1976 , stoned to death by mob and left with a sign around his neck proclaiming “Beware Afrikaaners.” The first child to die that day was called Hastings Ndlovu. According to Pat Motsiri, Orlando West is claiming struggle heritage through the Hector Pieterson Museum, while Hector Pieterson was from Jabavu. According to Pat Motsiri, his generation effectively struggled between 1980 and 1991, forcing the release of Nelson Mandela and negotiations with the apartheid regime while the 1976-generation was safely in exile. Nevertheless, this has not been recognized in any monument. After the abolition of apartheid, the generation from 1976 returned from exile, occupied important government and ANC positions, creating an abundance of 1976 memorials and refusing to acknowledge that this was only possible because of the younger generation’s struggle. He calls this a generational conflict. According to Archibald Dlamini, the park officer responsible for the Memorial Acre, he started working for the municipality in 1978. In 1981/82 , Isaac Makhele from Pimville, who used to work in the cemetery business, was the first developer of the park. It used to be just a normal park until City Parks decided to develop the Memorial Acre in 2006. In 2007 the work was stopped by the community. According to Brian Mokhele, he left the country in 1989 after he participated in the riots of 1986. But when he returned in 1999 he found that nothing had changed. He says that they were promised to be protected by the Constitution, but that reality is different. The police uses fear to suppress them so that they don’t come out to talk openly. He has been arrested twice, both times harassed and tortured by the police, but in the end always released without indictment. He says that this is their way to threaten communities to back off from politics. According to Moses, who is sitting outside rolling a joint, Brian knows everything. He tells Brian to tell me everything he knows. According to Brian Mokhele, Tsietsi Mashinini was possibly murdered in 1990 during his exile in New York. Two weeks before he was supposed to return to South Africa, his papers in order, he was found dead under mysterious circumstances. His coffin was sealed when he was buried. According to Pat Motsiri, he came up with the idea for the Memorial Acre in 2003 . He submitted the documents for the proposal to the council, which sidelined him as soon as the budget came out in 2005 . According to Brian Mokhele, there was on estimation R 41,000,000 spent to redesign the park and turn it into the Memorial Acre. The millions were divided by Amos Masondo, the mayor of Soweto, the local councilor Bongani D. Zondi, and the director of the city of Johannesburg, Pat Lephunya. They were dividing the money between several contractors: Tsietsi Mashinini’s brothers were involved in the development of the park, they got the tender to do the green areas, the landscaping. Construction was done by other companies, some did the paving, the toilets, etc. EMBA, a private company appointed by the municipality was in control of the money flow, but the money was quickly gone. According to Raymond Marlowe, the contractor bought a BMW with the money. According to Archibald Dlamini, the Mashinini brothers got the tender, so the space would look more like the other places around in Soweto. It was agreed that after they were done, they would return the property to the municipality. They did whatever they could do. According to Mafaisa, a member of the Jabavu business community, he was one of the contractors for the landscaping and the pavement under Mpho Mashinini, one of the brothers. He says that I should contact Mavi for information on Mpho. According to Poi Stuurman, a local youth worker, Mafaisa is one of the guys who ran away with the money. According to Mavi, Mpho Mashinini was never a contractor. The contracts were organized by Sbu Butelezi, the former head of the Gauteng Department for Public Works. The June 16 Foundation and the Mashinini brothers will be the beneficiaries of the park when it is finished. According to Brian Mokhele, City Parks did not accept the Memorial Acre because it was not finished. The rest of the year, the unfinished park is not maintained, as should have happened. This was done deliberately so that in the end they can just clean the whole thing up and have a reason to redo the whole park. According to Brian Mokhele, the Mashinini brothers now work for the government. People that manipulate for money purposes always come from the government’s side. Because the park was left unfinished, the people from the neighborhood are taking away the stones to decorate their own homes with. According to Archibald Dlamini, because City Parks doesn’t accept responsibility of the park, he officially has nothing the guard, except for his cottage, which is municipal property. The thieves come at night and destroy the park, but he cannot do anything because he is sleeping. According to the website of the Thanda Foundation on June 16, 2006 a bronze statue of Hector Pieterson, the first child to die in the 1976 protests, made by Kobus Hattingh and Jacob Maponyane was unveiled in the Maponya Mall in Soweto. The statue is sculpted after the famous image shot by Sam Nzima of Mbuyisa Makhubo carrying the dead body of the boy. The sculpture was sponsored by the Thanda Foundation, founded by the Swedish entrepreneur Dan Olofsson and South-African entrepreneur Matthews Phosa. According to the official website of the City of Johannesburg, the Memorial Acre and Artwork were unveiled in 2006. According to a blog post on sowetouprisings.com, the Memorial Acre was still under development on July 24, 2006. According to Archibald Dlamini, City Parks only cleans up the park once a year just before the June 16 celebrations. Everybody is waiting for the Mashinini brothers to finish their job. The last time he talked with them was in 2007 . According to a sign on the school grounds of the Morris Isaacson High School, the June 16 Trail will be finished in 2008 . According to a blog post on sowetouprisings.com, the Memorial Acre contains another monument erected in Tsietsi’s honor. The monument was created as part of the Sunday Times Heritage Public Art program. Its physical form resembles a giant book which symbolizes the crisis in education experienced in 1976. On the face of the book is the map of the route taken by the students from Morris Isaacson High School in Central Western Jabavu to Phefeni Junior Secondary in Orlando West (currently the site of the Hector Pieterson Museum), while the back cover of the ‘book’ is inscribed with a tribute to Tsietsi Mashinini. The monument was revealed on June 16, 2008 . According to Marcus Neustetter, the billboards on the Memorial Acre were part of a school project realized in 2008. Following several workshops, the students from different high schools along the June 16 Trail were invited to work with artists on the billboards, while the neighborhood community was invited to watch the process during the festivities on June 15 and 16, 2008 . The billboards were supposed to be removed because of construction works on the Memorial Acre, which never ended up happening. According to Brian Mokhele, the former toilet facilities were converted into a house for the park officer. This park officer has been working for city parks for more than 12-15 years, but does nothing here, because the park, including the new toilet buildings, is not finished. The government is now moving around looking for people to take this job because they stopped it. They confronted everybody who was going in and chased them away. According to John, in 2009 , some girls, around 16 or 17 years old, were raped by four men who had been drinking in a local shebeen. When the bar quit they said that they would go home by car, but instead raped the girls on the Memorial Acre nearby. This happened in the unfinished toilets, because the doors couldn’t be closed. According to Brian Mokhele, there used to be some fences around the park because of the construction work that was eventually stopped, but these were also stolen. According to Archibald Dlamini, people from the neighborhood started about two and a half years ago, and the last piece was stolen near the end of 2009 . Sometimes he would catch someone with a roll of fence, and then use it for his own cottage. According to the official website of the City of Johannesburg, a statue of Tsietsi Mashinini by Johannes Pokhela was revealed on June 16, 2010 , “Youth Day.” According to Shirley Makutoane, deputy principal of Isaac Morrison High School, the statue of Tsietsi Mashinini, funded by the June 16 Foundation, has temporarily been placed within the school perimeter. The statue will be moved to the Memorial Acre when it will be finished, in 2011 . According to Brian Mokhele, beside the June 16 Foundation, there is also a June 16 Memorial Acre Foundation. Both foundations are quarreling about the money involved in the Memorial Acre project. Nobody knows who’s involved in them. According to Marcus Neustetter, the June 16 Foundation consists of people that were part of 1976 protest movement, local government officials, representatives of the Hector Pieterson Museum, and the council. According to students from the Isaac Morrison High School, the statue of Tsietsi Mashinini is on the school ground because on the Memorial Acre it would be vandalized by youths from White City, an adjacent neighborhood. Accorcing to Brian Mokhele, the statue of Tsietsi should eventually be mounted on the Memorial Acre. It is wrong that the statue is in the school at the moment, because it is not a public school. He wants the statues to depict the massiveness of the force that was coming into Soweto after the protests. According to Brian Mokhele, City Parks, City of Jo’burg, City Lights, and SAPS are making some sort of plan to take the plan back. They want to remove the trees from the Memorial Acre, and redesign the Memorial Acre into a relaxing park, without political content. They want to depoliticize the square. In doing so,they will have their own employment and not use local workforces. According to Brian Mokhele, the community wants to remove the monuments, amphitheater, and sculptures from the Memorial Acre because they do not resemble anything. The sculptures should be depicting the truth of what happened, because the Memorial Acre is a political heritage site. He wants to involve the people that actually participated in the struggle to make the monument so that everyone can enjoy it and get a better understanding of the struggle heritage. Therefore, he proposes collective ideology in which everyone has a say. This would prevent future vandalization of the monument. According to Pat Motsiri, the sculptures must depict the event around June 16, 1976. Like the story of Dr Edelstein, who was pierced by pickaxes, forced into a garbage bin and burned alive. According to Jonas Staal, the Memorial Acre should be destroyed, its elements stacked on pallets, thus forming the Monument for the Distribution of Wealth . According to Mafaisa, his men can do the work quickly. He has about twenty men working under him. (shrink)

We examined 11-month-olds’ tendency to generalize properties to category members, an ability that may contribute to the inductive reasoning abilities observed in later developmental periods. Across 3 experiments, we tested 11-month-olds’ (N= 113) generalization of properties within the cat and dog categories. In each experiment, infants were familiarized to animal-sound pairings (i.e., dog-barking; cat-meowing), and tested on this association and the generalization of the sound property to new members of the familiarized categories. After familiarization with a single exemplar, 11-month-olds (...) generalized the sound to new category members that were both highly similar and less similar to the familiarized animal (Expt. 1). When familiarized with mismatched animal-sound pairings (Expt. 2; i.e., dog-meowing; cat-barking), 11-month-olds did not learn or generalize the sound properties, suggesting that infants have pre-existing expectations about the links between the characteristic sound properties and the animal categories. When familiarized with unfamiliar sound-animal pairings (Expt. 3; i.e., dog-unfamiliar sound), 11-month-olds linked the animals with the novel sounds but did not generalize to new category members. Taken together, these findings highlight the conditions under which young infants generalize properties from one exemplar to other category members. (shrink)

Over the past few decades, the question regarding the proper understanding of Diophantus’s method has attracted much scholarly attention. “Modern algebra”, “algebraic geometry”, “arithmetic”, “analysis and synthesis”, have been suggested by historians as suitable contexts for describing Diophantus’s resolutory procedures, while the category of “premodern algebra” has recently been proposed by other historians to this end. The aim of this paper is to provide arguments against the idea of contextualizing Diophantus’s modus operandi within the conceptual framework of the ancient analysis (...) and to examine the few instances, in the preserved books of the Arithmetica, which might be regarded as linked to practices belonging to the field of analysis.

The aim of this study is to examine the decision-making processes at work among French buyers—whether beginners or more experienced individuals, when confronted with a dilemma involving an ethical or non-ethical choice to be made. We go on to illustrate these dilemmas through the use of five original scenarios that reproduce typical situations that arise in a purchasing context in relation to the environment, physical integrity, conflict of interest, or paternalism. Based on 172 participants, the results of our study show (...) that, ethical decision-making depends very clearly on two main factors: expertise and gender. The study also reveals that there is not always a coherent link between ethical choices made and the reasons and justifications given for those choices. Ethical options chosen are not exclusively justified on the grounds of purely ethical reasons but also on the grounds of commercial or economic reasons, or else reasons of avoidance. (shrink)

In deductive theorizing using mathematics as our theorizing tool, nature is known to routinely help us discover new empirical truths about itself, whether we want the help or not (“generative phenomenon”). Why? That’s because, I argue, some of our deductive inference rules are themselves of empirical origin, thereby providing nature with a seemingly-trivial but crucial link to our mind’s reason.
