We reported a series of experiments carried out to confront the underlying intuitions of value-based argumentation frameworks (VAFs) with the intuitions of ordinary people. Our goal was twofold. On the one hand, we intended to test VAF as a descriptive theory of human argument evaluations. On the other, we aimed to gain new insights from empirical data that could serve to improve VAF as a normative model. The experiments showed that people’s acceptance of arguments deviates from VAF’s (...) semantics and is rather correlated with the importance given to the promoted values, independently of the perceptions of argument interactions through attacks and defeats. Furthermore, arguments were often perceived as promoting more than one value with different relative strengths. Individuals’ analyses of scenarios were also affected by external factors such as biases and arguments not explicit in the framework. Finally, we confirmed that objective acceptance, that is, the acceptance of arguments under any order of the values, was not a frequent behavior. Instead, participants tended to accept only the arguments that promoted the values they subscribe. (shrink)

The analysis of how social conventions emerge and become established is rightly viewed as a significant study of great relevance to models of legal and social systems. Such conventions, however, do not operate in a monotonic fashion, i.e. the fact that a convention is recognised and complied with at some instant is no guarantee it will continue to be so indefinitely. In total rules and protocols may evolve, with or without the consent of individual members of the society, even to (...) the extent that some cease to be observed or effective. In this paper we examine a framework for examining such changes in behavioural conventions that uses a proposed “taxonomy of social conventions” as the basis of a qualitative model deriving from value-based argument systems.

Compliance is often achieved ‘by design’ through a coherent system of controls consisting of information systems and procedures. This system-based control requires a new approach to auditing in which companies must demonstrate to the regulator that they are ‘in control’. They must determine the relevance of a regulation for their business, justify which set of control measures they have taken to comply with it, and demonstrate that the control measures are operationally effective. In this paper we show how (...) class='Hi'>value-based argumentation theory can be applied to the compliance domain. Corporate values motivate the selection of control measures (actions) which aim to fulfil control objectives, i.e. adopted norms (goals). In particular, we show how to formalize the audit dialogue in which companies justify their compliance decisions to regulators using value-based argumentation. The approach is illustrated by a case study of the safety and security measures adopted in the context of EU customs regulation. (shrink)

Designing security measures often involves trade-offs between various types of objectives. Multiple stakeholders may have conflicting demands and may have different ideas on how to resolve the resulting design conflicts. This paper reports on an application of value-sensitive design. Based on argumentation theory and social values, the paper develops a structured approach for discussing design conflicts, called value-based argumentation. The application domain examined in the paper is concerned with physical safety and security issues that (...) arise in cross-border shipments. We first identify the kinds of dialogues that take place in this domain, in particular, audit dialogues to determine whether security measures comply with regulations. Based on argumentation theory we develop a formal language and a diagramming approach intended to facilitate parties in identifying, discussing and reaching agreement about security risks and corresponding mitigation measures. Trade-offs can be dealt with by making underlying values explicit. Using a stylized example, the approach was successfully taught to practitioners working with EU customs regulations. Practitioners generally found the approach helpful, in particular to bring out implicit underlying motivations. We conclude by discussing how our approach can be generalized to other kinds of dialogues involving design conflicts. (shrink)

When bringing philosophical attention to bear on social movement slogans in general, philosophers have often focused on their communicative nature—particularly the hermeneutical failures that arise in discourse. Some of the most popular of these failures are illustrated in ‘all lives matter’ retorts to ‘black lives matter’ pronouncements. Although highlighting and criticizing these failures provides much needed insight into social movement slogans as a communicative practice, I claim that in doing so, philosophers and slogans’ users risk placing too much importance on (...) outgroup understandings. This emphasis is misguided because gaining such uptake is not required of particular slogans to perform their functions; indeed it is an inherent risk of them. I show how such an emphasis can also be distracting to users. Since social movement slogans that express values are first and foremost for users, I argue for a shift in focus in what these slogans (such as ‘Black Is Beautiful’ and the more recent ‘Black Lives Matter’) do for users, as well as what they demand from users and enable them to express. When slogans have done these things, regardless of uptake, we can say they have performed one of their key functions. (shrink)

In this paper, I explore the prospects for risk-based arguments in favour of anti-natalism, which explain the wrongness of procreation in terms of wrongful risk-imposition on the resultant child. After considering and rejecting two risk-based arguments from the existing literature - David Benatar's and Matti Häyry's - I propose a more promising version that focuses on the lack of appropriate justification for imposing the risks of existence, namely, one that refers to the essential interests of the child on (...) whom those risks are imposed. The paper proceeds in four parts. In Part 2, I set the stage for my discussion by clarifying the basic structure of risk-based arguments and identifying some of their important features. In Parts 3-5, I consider three distinct risk-based arguments for anti-natalism and argue that only the third, justificatory argument has the potential to be successful. (shrink)

The persuasiveness of an argument depends on the values promoted and demoted by the position defended. This idea, inspired by Perelman’s work on argumentation, has become a prominent theme in artificial intelligence research on argumentation since the work by Hafner and Berman on teleological reasoning in the law, and was further developed by Bench-Capon in his value-based argumentation frameworks. One theme in the study of value-guided argumentation is the comparison of values. Formal models (...) involving value comparison typically use either qualitative or quantitative primitives.

The article argues that liberty-based arguments alone are not enough to justify a universal basic income, whether as a replacement of current welfare programs, or as an addition to them. Appeals to negative liberty, real freedom, republican liberty, and autonomy cannot show that a universal basic income is superior to (all kinds of) conditional benefits. To do so, proponents of a universal basic income will have to invoke values beyond liberty.

There are emotively powerful words that can modify our judgment, arouse our emotions, and influence our decisions. The purpose of this paper is to provide instruments for analyzing the structure of the reasoning underlying the inferences that they trigger, in order to investigate their reasonableness conditions and their persuasive effect. The analysis of the mechanism of persuasion triggered by such words involves the complex systematic relationship between values, decisions, and emotions, and the reasoning mechanisms that have been investigated under the (...) label of “heuristics.” On the one hand, arguing using ethical words is shown to sometimes involve value-based practical reasoning grounded on evaluative classifications stemming from hierarchies of values and maxims of experience. On the other hand, ethical words provide representations bound to the interlocutor’s experiences and judgments, which trigger specific emotions yielding a particular reaction. This chain of judgments and reactions and the potential fallaciousness thereof can be inquired into by examining the relationship between the heuristic processes of reasoning and the more complex argumentative structure that the use of such words involves. The analysis of the 2013 Italian political campaign and the ad hominem arguments used by the political candidates shows the different strategies and counterstrategies for the manipulation of emotions.

There is an increasing need for norms to be embedded in technology as the widespread deployment of applications such as autonomous driving, warfare and big data analysis for crime fighting and counter-terrorism becomes ever closer. Current approaches to norms in multi-agent systems tend either to simply make prohibited actions unavailable, or to provide a set of rules (principles) which the agent is obliged to follow, either as part of its design or to avoid sanctions and punishments. In this paper we (...) argue for the position that agents should be equipped with the ability to reason about a system’s norms, by reasoning about the social and moral values that norms are designed to serve; that is, perform the sort of moral reasoning we expect of humans. In particular we highlight the need for such reasoning when circumstances are such that the rules should arguably be broken, so that the reasoning can guide agents in deciding whether to comply with the norms and, if violation is desirable, how best to violate them. One approach to enabling this is to make use of an argumentation scheme based on values and designed for practical reasoning: arguments for and against actions are generated using this scheme and agents choose between actions based on their preferences over these values. Moral reasoning then requires that agents have an acceptable set of values and an acceptable ordering on their values. We first discuss how this approach can be used to think about and justify norms in general, and then discuss how this reasoning can be used to think about when norms should be violated, and the form this violation should take. We illustrate how value based reasoning can be used to decide when and how to violate a norm using a road traffic example. We also briefly consider what makes an ordering on values acceptable, and how such an ordering might be determined. (shrink)

This paper examines the definition and implementation of community -based alternative food systems,drawing on examples from British Columbia, Canada. We seek to reframe the goals of AFS by focusing on the values associated with food production, distribution and consumption strategies. We argue that current AFS thinking suffers from an over reliance on policies reflecting single rather than multiple objectives and arguments over specific alternatives rather than a values -focused debate.A decision-focused approach, using a consequence matrix, is proposed to link (...) people's expressed values to food policy responses and clarify trade-offs across options. This reframing should encourage new dialogue, new policy alternatives, and increased acceptance of actions supporting AFS. (shrink)

In this paper I sketch a novel interpretationist account of linguistic content that has important consequences for thinking about intentionality. I solve the challenge presented by a foundational indeterminacy of reference argument to the effect that the meaning of linguistic expressions is radically indeterminate. Happily, my solution doesn’t require positing natural properties as “reference magnets”. Non-deflationist rivals to interpretationist metasemantics include various kinds of causal theories such as Fodor-style asymmetric-dependence accounts and Millikan-style teleosemantics. These accounts face their own indeterminacy challenges (...) that have yet to be solved, as well as similar indeterminacy of reference challenges at the level of individual words. Moreover, they must contend with our apparent reference to things that we are not plausibly causally acquainted with. If indeterminacy of reference arguments can be answered and we can avoid dubious use of natural properties, an interpretationist account like my own will be the strongest contender.. (shrink)

This paper presents an extended version of the Quantified Argument Calculus (Quarc). Quarc is a logic comparable to the first-order predicate calculus. It employs several nonstandard syntactic and semantic devices, which bring it closer to natural language in several respects. Most notably, quantifiers in this logic are attached to one-place predicates; the resulting quantified constructions are then allowed to occupy the argument places of predicates. The version presented here is capable of straightforwardly translating natural-language sentences involving defining clauses. A three-valued, (...) model-theoretic semantics for Quarc is presented. Interpretations in this semantics are not equipped with domains of quantification: they are just interpretation functions. This reflects the analysis of natural-language quantification on which Quarc is based. A proof system is presented, and a completeness result is obtained. The logic presented here is capable of straightforward translation of the classical first-order predicate calculus, the translation preserving truth values as well as entailment. The first-order predicate calculus and its devices of quantification can be seen as resulting from Quarc on certain semantic and syntactic restrictions, akin to simplifying assumptions. An analogous, straightforward translation of Quarc into the first-order predicate calculus is impossible. (shrink)

In this paper, I explore one line of argument for the Humean Theory of Reasons, the view that all normative reasons are based on desires. Then, I suggest a way to block that argument inspired by Aquinas’s discussions on choice, will, and indeterminacy of reason alone.

There are emotively powerful words that can modify our judgment, arouse our emotions and influence our decisions. This paper shows how the use of emotive meaning in argumentation can be explained by showing how their logical dimension, which can be analysed using argumentation schemes, combines with heuristic processes triggered by emotions. Arguing with emotive words is shown to use value-based practical reasoning grounded on hierarchies of values and maxims of experience for evaluative classification.

The idea that professional practices such as education should be based upon or at least be informed by evidence continues to capture the imagination of many politicians, policy makers, practitioners and researchers. There is growing evidence of the influence of this line of thought. At the same time there is a growing body of work that has raised fundamental questions about the feasibility of the idea of evidence-based or evidence-informed practice. In this paper I make a further contribution (...) to this discussion through an analysis of a number of assumptions that inform the discussion. I focus on the epistemological, ontological and praxeological dimensions of the discussion and in each domain identify a deficit. In the epistemological domain there is a knowledge deficit, in the ontological domain an effectiveness or efficacy deficit and in the practice domain an application deficit. Taken together these deficits not only raise some important questions about the very idea of evidence-based practice but also highlight the role of normativity, power and values. Against this background I outline the case for the idea of value-based education as an alternative for evidence-based education. As I am generally concerned about the expectations policy makers hold about what evidence can and should achieve in professional practices such as education, my contribution is primarily meant to provide educators and other professionals with arguments that can help them to resist unwarranted expectations about the role of evidence in their practices and even more so of unwarranted interventions in their practices.

For many persons, ‘Holocaust‐abomination’is a fixed point on their moral compass: if anything can be evil, it was. Yet at least one of the justifications deployed by its perpetrators (the eugenics argument) invokes widely‐held values concerning human health and procreation. Hence persons endorsing many current activities based on those values (e.g. genetic counselling) have been charged with being on a morally deplorable slippery slope. This paper sketches the necessary structure of a moral position capable of consistently embracing those values (...) without placing its occupants on that slippery slope. (shrink)

Respect for autonomy is typically considered a key reason for allowing physician assisted suicide and euthanasia. However, several recent papers have claimed this to be grounded in a misconception of the normative relevance of autonomy. It has been argued that autonomy is properly conceived of as a value, and that this makes assisted suicide as well as euthanasia wrong, since they destroy the autonomy of the patient. This paper evaluates this line of reasoning by investigating the conception of valuable (...) autonomy. Starting off from the current debate in end-of-life care, two different interpretations of how autonomy is valuable is discussed. According to one interpretation, autonomy is a personal prudential value, which may provide a reason why euthanasia and assisted suicide might be against a patient’s best interests. According to a second interpretation, inspired by Kantian ethics, being autonomous is unconditionally valuable, which may imply a duty to preserve autonomy. We argue that both lines of reasoning have limitations when it comes to situations relevant for end-of life care. It is concluded that neither way of reasoning can be used to show that assisted suicide or euthanasia always is impermissible. (shrink)

What makes individual freedom valuable? People have always believed in freedom, have sought it, and have sometimes fought and died for it. The belief that it is something to be valued is widespread. But does this belief have a rational foundation? This book examines answers to these questions that are based on the welfare of the person whose freedom is at stake. There are various conceptions of a worthwhile life, a life that is valuable for the person whose life (...) it is. These conceptions will be examined to see whether they are plausible and what their connection, if any, is to freedom. Are they compelling foundations for freedom? Does freedom make a person’s life better or would his/her welfare be advanced by restricting freedom? (shrink)

According to an attractive and widely held view, all practical reasons are explained in terms of the (instrumental or final) value of the action supported by the reason. I argue that this theory is incompatible with plausible assumptions about the practical reasons that correspond to certain moral rights, including the right to a promised action and the right to an exclusive use of one’s property. The argument is an explanatory rather than extensional one: while the actions supported by the (...) relevant reasons (e.g. keeping a valid promise or respecting property) can be argued to have a certain kind of value, I argue that this value presupposes a moral right, and therefore cannot explain the reason. Reflection on such cases suggest the conclusion that reasons that are subject to normative powers are generally not value-based. This also has important implications for the dialectic between ‘value-first’ and ‘reasons-first’ approaches to normativity. (shrink)

If the point of argument is to produce conviction, an argument tor a foregone conclusion is pointless. I maintain, however, that an argument makes a variety of cognitive contributions, even when its conclusion is already believed. It exhibits warrant. It affords reasons that we can impart to others. It identifies bases tor agreement among parties who otherwise disagree. It underwrites confidence, by showing how vulnerable warrant is under changes in background assumptions. Multiple arguments for the same conclusion show how our (...) beliefs hang together. (shrink)

Peer review of manuscripts for biomedical journals has become a subject of intense ethical debate. One of the most contentious issues is whether or not peer review should be anonymous. This study aimed to generate a rich, empirically-grounded understanding of the values held by journal editors and peer reviewers with a view to informing journal policy. Qualitative methods were used to carry out an inductive analysis of biomedical reviewers’ and editors’ values. Data was derived from in-depth, open-ended interviews with journal (...) editors and peer reviewers. Data was “read for” themes relevant to reviewer anonymisation and interactions among editors, reviewers, and authors. Editors and peer reviewers provided three arguments that would support a more open and interactive peer-review process. First, a number of participants emphasised the importance of not only ensuring the scientific quality of published research but also nurturing their colleagues and supporting their communities. Second, many spoke about the ongoing moral responsibilities that reviewers and editors felt toward authors. Finally, participants spoke at length about their enjoyment of social interactions and of the value of collective, rather than isolated, reasoning processes. Whether or not journal editors decide to allow anonymous review , the values of editors and reviewers need to be seriously addressed in codes of publication ethics, in the management of biomedical journals, and in the establishment of journal policies.

This article studies argumentation for acceptability of corporate environmental actions in corporate environmental statements, with emphasis on stakeholder relations and environmental values. Stakeholder theory is commonly taken as the basis for corporate environmental management, and rhetoric typical of the stakeholder approach dominates the field. Although environmental issues are strongly charged with values, the dominant stakeholder approach does not stress the value dimension. The data of the study consists of environmental statements by Finnish forerunning business corporations in the forefront (...) of corporate environmental responsibility. The results of the study indicate that the statements argue for the acceptability of corporate environmental actions through three power-related rhetorical forms that are competing ways to produce acceptability in the data: dominance, subordination and equality, and joint action. Each rhetorical form describes a power-based relationship between stakeholders and the corporation and leans on a specific value type producing legitimacy for that rhetoric form. (shrink)

A models-based approach has been advocated as a means of overcoming the serious limitations of the traditional approach to physical education. One of the difficulties with this approach is that physical educators have sought to use it to achieve diverse and sometimes competing educational benefits, and these wide-ranging aspirations are rarely if ever achieved. Models-based practice offers a possible resolution to these problems by limiting the range of learning outcomes, subject matter and teaching strategies appropriate to each pedagogical (...) model and thus the arguments that can be used for educational value. In this article, two examples are provided to support a case for educational value. This case is built on an examination of one established pedagogical model, Sport Education, which is informed by a perspective on ethics. Next, I consider Physical Literacy which, I suggest, is an existentialist philosophical perspective that could form the basis of a new pedagogical model. It is argued, in conclusion, that a models-based approach along with a reconstructed notion of educational value may offer a possible future for physical education that is well grounded in various philosophical arguments and the means to facilitate a wide range of diverse individual and social educational ?goods?

Research on the role of values in science and objectivity has typically approached trust through its epistemic aspects. Yet, recent work on public trust in science has emphasized the role of non-epistemic values in building and maintaining trust. This paper will use a concept of trust that adds concerns about justice to epistemic conditions to investigate this problem in relation to public health. I will argue that trust-conducive values, particularly justice, are relevant in deciding which value influences are legitimate (...) in scientific decision-making. Drawing on public health ethics, I will provide a consequentialist justification for employing trust-conducive values. While several concepts of justice have been explored in the context of public health, I will further draw on public health ethics, focusing on a view that brings together both distributive and procedural aspects. For illustration, I will use the case of cardiovascular disease prevention, particularly how concerns about justice apply when choosing between population-based and individual-based approaches.

The purpose of this paper is to inquire into the relationship between persuasive definition and common knowledge (propositions generally accepted and not subject to dispute in a discussion). We interpret the gap between common knowledge and persuasive definition (PD) in terms of potential disagreements: PDs are conceived as implicit arguments to win a potential conflict. Persuasive definitions are analyzed as arguments instantiating two argumentation schemes, argument from classification and argument from values, and presupposing a potential disagreement. The argumentative structure (...) of PDs reveals different levels of disagreement, and different pos-sibilities of resolving the conflict or causing dialogical deadlock. (shrink)

This chapter argues that nonepistemic or contextual values should not be systematically excluded from any of the four categories of value judgments considered in Chapter 2. The argument rests on three major principles. First, the “ethics” principle is that scientists have ethical responsibilities to consider the major societal consequences of their work and to take reasonable steps to mitigate harmful effects that it might have. Second, the “uncertainty” principle is that those who are researching policy‐relevant topics often face situations (...) in which scientific information is uncertain and incomplete, and they have to decide what standard of proof to demand before drawing conclusions. Third, the “no‐passing‐the‐buck” principle states that it is frequently socially harmful or impracticable for scientists to respond to uncertainty by completely withholding their judgment or providing uninterpreted data to decision makers. Based on this third principle, scientists cannot always leave difficult value judgments about interpreting uncertain evidence up to policy makers. Therefore, there are sometimes ethical reasons for scientists to factor societal considerations into their responses to uncertainty even when they address judgments about choosing scientific language or interpreting evidence. The upshot of this chapter is that administrators and policy makers need to find ways to limit the influences of powerful interest groups without naively trying to seal scientific research off from all societal influences and considerations.

The paper proposes a general account of how real-life practical argumentation can be explained on the basis of empirical data regarding cultural value priorities. This general account is built upon Schwartz’s theory of human values and the value-based theory of normative reasons for action, as well as upon the principle that an agent ought to perform an action, if and only if the total weight of the reasons for the agent to perform the action is greater (...) than the total weight of the reasons for the agent not to perform the action. The practical significance of this general account is demonstrated by applying it in case studies of two real-life instances of practical argumentation – the 2018 Bulgarian debate about the ratification of the Istanbul convention and the 2015 Putin-Obama discussion about the intervention in the Syrian civil war. In both case studies, empirical data regarding cultural value priorities is gathered from the results from the European Social Survey. The theoretical significance of the general account is demonstrated through comparison and contrast with related research. (shrink)

In his recent book Abortion and Unborn Human Life, Patrick Lee develops an argument for foetal personhood based on intrinsic value. Lee argues that since the foetus is identical with the rational, self‐conscious being who will exist a few years later, and since this rational, self‐conscious being indisputably is intrinsically valuable, therefore the foetus must already be intrinsically valuable; for nothing can come to be at one time but become intrinsically valuable at another. I show that this argument (...) fails on two counts. First, the crucial premise that a thing’s intrinsic value must derive from its essential properties is question‐begging and devoid of support. Second, that premise is inconsistent with the pro‐life position. (shrink)

Evidence-based practice in education involves basing decisions about what to do on evidence about the relative effectiveness of available interventions (e.g. programmes, products, practices). This article considers two influential critiques of evidence-based education (EBE) pertaining to its treatment of values. The ‘general critique’ condemns EBE for excluding values from decisions about what to do in education. The ‘specific critique’ condemns EBE for relying on a deterministic view of causality in education which disregards the complex, value-laden nature of (...) educational contexts. I argue that virtually all versions of EBE escape the general critique, including the dominant intervention-centred approach that relies on experimental research to discover ‘what works’, because the predictions EBE aims to support are only one premise in a broader normative argument. Further, intervention-centred EBE can avoid much of the specific values-based critique because it is consistent with a probabilistic, rather than deterministic, understanding of causality. However, I argue that only a context-centred approach to EBE that relies on evidence about the specific target setting from local sources in addition to evidence from theory and mixed methods research can fully address the specific critique by accommodating critics’ descriptive claims about the nature of educational contexts.

Pleasure is widely thought to have intrinsic value. However, this thesis has been threatened by the argument that pleasure is a mental state that essentially involves the subject’s conative attitudes. Its value, then, would be subjective. Though the existing version of the argument can be resisted by simply rejecting the attitudinal theories of pleasure on which it is based, I will develop a new and more general version based on the reasonable hypothesis that the phenomenal character (...) of pleasure is reducible to a physical or functional property. If this new version is convincing, then the most promising way to secure the intrinsicality of the value of pleasure and to escape all versions of the subjectivity argument might be to embrace a non-reductionist account of pleasure and its value.

The participation of vulnerable patients in clinical research poses apparent ethical dilemmas. Depending on the nature of the vulnerability, their participation may challenge the ethical principles of autonomy, non-maleficence, or justice. On the other hand, non-participation may preclude the building of a knowledge base that is a prerequisite for defining the optimal clinical management of vulnerable patients. Such clinical uncertainty may also incur substantial economic costs. We present the participation of pre-menopausal women with atrial fibrillation in trials of novel oral (...) anticoagulant drugs as a case study. Due to their non-participation in pivotal trials, it is uncertain whether for them, the risks that are associated with these drugs are outweighed by the advantages compared with conventional treatment. We addressed the question whether research of this new class of drugs in this subgroup would be appropriate from both, an ethical as well an economic perspective. We used the method of specifying norms as a wider framework to resolve the apparent ethical dilemma, while incorporating the question whether research of oral anticoagulants in premenopausal women with atrial fibrillation can be justified on economic grounds. For the latter, the results of a value-of-information analysis were used. Further clinical research on NOACs in premenopausal women with atrial fibrillation can be justified on both, ethical and economic grounds. Addressing apparent ethical dilemmas by invoking a method such as specifying norms can improve the quality of public practical reasoning. As such, the method should also prove valuable to committees that have formally been granted the authority to review trial protocols and proposals for scientific research. (shrink)

Analogously to Kuhn’s and Hanson’s understanding of observation as theory-impregnated, we try to test the hypothesis that observation and interpretation might also be value-impregnated. We use a written examination task for medical students who were asked to read and interpret a text where the authors provide arguments pro et contra euthanasia. Afterwards the students were asked to provide their own reflected opinion on the issue. We found that medical students who were against and indecisive provided interpretations of the text (...) which accorded with their own reflected opinions (P = 0.02), indicating that their interpretations were influenced by their own values. When including those who were pro euthanasia, the association was no longer significant. Although the present investigation was a small pilot-study, we obtained partial support for our hypothesis and have adjusted it to read as follows: observations and interpretations might be value-impregnated for respondents who have rather strong value-based attitudes. We think the adjusted hypothesis deserves to be further examined. (shrink)

This article applies tools from argumentation theory to slippery slope arguments used in current ethical debates on genetic engineering. Among the tools used are argumentation schemes, value-based argumentation, critical questions, and burden of proof. It is argued that so-called drivers such as social acceptance and rapid technological development are also important factors that need to be taken into account alongside the argumentation scheme. It is shown that the slippery slope argument is basically a reasonable (...) form of argument, but is often flawed when used in ethical debates because of failures to meet the requirements of its scheme.

This paper introduces an argumentation framework, differential equation based on cost for recursive argumentation graph (DECRAG), for natural language arguments. DECRAG’s argumentation graph is so flexible that attack and support relations, recursive relations, similarity relations between arguments, and default values can be represented. The base score and the necessity relation can be simulated by the framework. DECRAG maps an argumentation graph to a general system, and the solution of the system is used as the values (...) of the nodes and edges of the graph. We illustrate interesting solutions such as multiple fixed points for the dilemma of even-length cycles and limit cycles for the paradox of odd-length cycles. DECRAG also satisfies many important properties. In this paper, focusing on the theoretical aspect of DECRAG, we show examples, properties, and evaluations of the framework. (shrink)

This article introduces a method for detecting argumentative communities in semi-structured debates, which are supported by ad-populum argumentation schemes, as proposed by Walton. In these communities, opinions are characterized by their level of cohesion and the argumentative groups involved. In this context, we present a semi-structured argumentation formalism for analyzing social media debates and demonstrate how large language models can assist in instantiating the proposed formalism. We use conceptualizations, similarity and valued-based argumentation frameworks to assess argument (...) cohesion and strength. Additionally, we model discursive interactions to analyze how stances influence one another and classify argumentative communities based on popular opinion argumentation schemes. We show that these communities can be modeled using such schemes, relying on public perception and consensus. (shrink)

[1st paragraph] A philosophical discussion on evidence-based medicine (EBM) can be probably perceived almost as an oxymoron. How can “the process of systematically finding, appraising, and using contemporaneous research findings as the basis for clinical decisions” (Jenicek 2012: 23) be compatible with the critical and systematic examination of fundamental problems such as the nature of being, reality, thinking, values and perception? How can a scientific field focused mainly on the search and evaluation of evidence and aimed at solid quantifications (...) of hypotheses (Jenicek 2003: 70) be approachable from a perspective that is characterized by probable or defeasible arguments? The challenge of this special issue is to show how a philosophical perspective on evidence is not opposed to, but rather at the grounds of evidence-based medicine. (shrink)

In evidence-based medicine (EBM), methodology has become the central means of determining the quality of the evidence base. The “gold standard” method, the randomised, controlled trial (RCT), imbues medical research with an ethos of disinterestedness; yet, as this essay argues, the RCT is itself a rhetorically interested construct essential to medical-professional boundary work. Using the example of debates about methodology in EBM-oriented research on complementary and alternative medicine (CAM), practices not easily tested by RCTs, I frame the problem of (...) method as a fundamentally rhetorical problem, situated within a boundary drama, and deeply rooted in the discursive practices of science and medicine. The genre of the RCT report, for example, idealises the research process and can tilt the course of arguments about CAM, while the notion of efficacy can function as a rhetorically mobile boundary object that can redefine the very terms of debate. I suggest herein that arguments about method in CAM debates can productively be read, metonymically, as expressions of more general anxieties in medicine about knowledge and evidence, community values, and professional boundaries; as such, these debates can illuminate some of the rhetorical dimensions of EBM.

In a rare book published in Trivandrum (1927), entitled Sphoṭasiddhiḥ Bharatamiśrapranītā , we find an interesting argument in defense of sphoṭa -theory, based on āgamic quotations, especially RV X, 71, 4 (the stanza where the poet describes his own activity in perceiving the essence of Speech as like a beloved woman naked). The main idea is that the numerous word sphoṭas , as an atemporal multiplicity, free from any sensuous quality, were the objects of the Ṛṣis’ primordial intuition. So (...) the internal diversity of the Veda is not a mere subjective convention in order to adapt the highest truth to limited human minds. The absolute brahman has an objective cosmogonical power of which the temporal mutiplicity is only the very last result. There is also an intermediate ideal multiplicity, which the Veda, as eternal and transcending the guru-śiṣya transmission, consists in. (shrink)

We propose a revision operator on a stratified belief base, i.e., a belief base that stores beliefs in different strata corresponding to the value an agent assigns to these beliefs. Furthermore, the operator will be defined as to perform the revision in such a way that information is never lost upon revision but stored in a stratum or layer containing information perceived as having a lower value. In this manner, if the revision of one layer leads to the (...) rejection of some information to maintain consistency, instead of being withdrawn it will be kept and introduced in a different layer with lower value. Throughout this development we will follow the principle of minimal change, being one of the important principles proposed in belief change theory, particularly emphasized in the AGM model. Regarding the reasoning part from the stratified belief base, the agent will obtain the inferences using an argumentative formalism. Thus, the argumentation framework will decide which information prevails when sentences of different layers are used for entailing conflicting beliefs. We will also illustrate how inferences are changed and how the status of arguments can be modified after a revision process. (shrink)

This paper is concerned with the processing of informal arguments, that is, arguments involving “probable truth.” A model of informal argument processing is presented that is based upon Hample's (1977) expansion of Toulmin's (1958) model of argument structure. The model postulates that a claim activates an attitude, the two components forming a complex that in turn activates reasons. Furthermore, the model holds occurrence of the reason, or possibly the claim and the reason, activates values. Three experiments are described that (...) provide support for the model. (shrink)

Values-based medicine derives from an approach first introduced into the philosophy of psychiatry, which aims to demonstrate that the reality of mental illness is not inconsistent with the scientific status of medicine. Associated primarily with the work of K.W.M. Fulford, the argument is that practitioners need to be ethical anti-descriptivists if they are to avoid the authoritarianism of evidence-based medicine, which overlooks the fact that genuine value conflicts can arise during all clinical encounters, and that psychiatry is (...) just the most explicit area in which these occur. This paper takes a philosophically therapeutic line and argues that, by reducing values to the status of preferences, antidescriptivism undermines the value of 'value' and leaves the practitioner with a reduced ability to discern and negotiate genuine conflicts of value. The conclusion is that patients should be respected, not as instantiations of preferences but as valuers ; and that this requires practitioners to become more cosmopolitan and sympathetic, not more theoretically sophisticated.

In some cases of disagreement, particularly in ethics and law, it is impossible to provide any conclusive demonstration. The role of argument in such cases is to persuade rather than to prove. Drawing on ideas ofPerelrnan, we argue that persuasion in such cases relies on a recognition that the strength of such arguments will vary according to their audience, and depends on the comparative weight that the audiences gives to the social values that it advances. To model this, we introduce (...) the notion of Value-based Argumentation Frameworks (VAFs), an extension of Argumentation Frameworks as originally introduced by Dung. We then describe a dialogue game based on VAFs, designed to model persuasive argumentation, which we illustrate with a widely discussed ethical problem. (shrink)

What is An analysis of Requiredness? This paper presents three versions of an argument in defence of a form of value-realism. The argument is based on a principle of nonreducibility of integral wholes to sums, as informally developed by Gestalt theorists, systematically worked out by Husserl in his III Logical Investigation on wholes and parts, and exploited by Max Scheler’s theory of material and axiological apriori.

Dominant approaches to punishment tend to downplay the socio-emotional dimension of perpetrators. This attitude is inconsistent with the body of evidence from social and affective neuroscience and its adjacent disciplines on the crucial role of emotions and emotion-related skills coupled with positive social stimuli in promoting prosocial behavior. Through a literature review of these studies, this article explores and assesses the implications that greater consideration of emotional and social factors in sentencing and correctional practices might have for conventional punitive approaches (...) to crime. It argues that proper attention to these factors within the judgment of offending can challenge the tenets of dominant punitive ideologies and responses to crime. It further emphasizes the higher rationality and effectiveness of a paradigm of justice that aims for the social reintegration of perpetrators through a path to self-reform and change that is based on relational and inclusionary processes in the least confining environments possible to still ensure public safety. Hence, this article supports the pursuit of social rehabilitation as the ultimate goal of criminal justice. (shrink)

In this paper, we study conditional preferences in abstract argumentation by introducing a new generalization of Dung-style argumentation frameworks (AFs) called Conditional Preference-based AFs (CPAFs). Each subset of arguments in a CPAF can be associated with its own preference relation. This generalizes existing approaches for preference-handling in abstract argumentation, and allows us to reason about conditional preferences in a general way. We conduct a principle-based analysis of CPAFs and compare them to related generalizations of AFs. (...) Specifically, we highlight similarities and differences to Modgil’s Extended AFs and show that our formalism can capture Value-based AFs. Moreover, we show that in some cases the introduction of conditional preferences leads to an increase in computational complexity. (shrink)

Against the background of high demand for protein-rich feed in the EU and the environmental degradation associated with intensive livestock farming, insect-based feed is discussed as a potential sustainable alternative to conventional feed. However, the establishment of such an innovation depends not only upon technical and economic feasibility, but also on social factors impacting acceptability. The aim of this paper was to determine the acceptability of different social actor groups towards the use of insects as livestock feed, and to (...) gain insights into value-based arguments leading to positive or negative attitudes and perceived benefits and risks. By means of qualitative content analysis, we analysed responses of an EU public consultation process linked to the authorization of insect protein in pig and poultry feed. We found a broad range of value-based arguments that influence the complex judgement process of acceptability that have been neglected in prior quantitative surveys. In particular, our results bring forward more critical voices, such as animal welfare concerns and scepticism that insect-based feed can contribute to a more sustainable livestock system. Based on these findings, we discuss whether insects as feed are a viable contribution to a sustainability-oriented transformation of the agri-food system. We conclude that under certain conditions (when raised on low-value organic side streams such as manure) insect-based livestock feed may contribute to incremental sustainability improvements. Overall, however, the innovation has limitations, not only in terms of regulatory conditions but especially with regard to ethical concerns. (shrink)

This paper studies the use of hypothetical and value-based reasoning in US Supreme-Court cases concerning the United States Fourth Amendment. Drawing upon formal AI & Law models of legal argument a semi-formal reconstruction is given of parts of the Carney case, which has been studied previously in AI & law research on case-based reasoning. As part of the reconstruction, a semi-formal proposal is made for extending the formal AI & Law models with forms of metalevel reasoning in (...) several argument schemes. The result is compared with Rissland’s (1989) analysis in terms of dimensions and Ashley’s (2008) analysis in terms of his process model of legal argument with hypotheticals. (shrink)
