The aim of this paper is to explore Deleuze's use of Kant's argument from incongruent counterparts, which Kant uses to show the existence of what he calls an “internal difference” within things. I want to explore how Deleuze draws out an important distinction between the concept and the Idea, and provides an incisive account of his relationship to both the Kantian and Leibnizian projects. First, I look at Kant's use of the argument to provide a refutation of the Leibnizian account (...) of space, before showing how this criticism in fact rests on the question of the conceptual determination of object. Second, I show how Deleuze develops a taxonomy of difference on the basis of his reading of Kant's argument. Finally, I look at what Deleuze sees as the limitations in Kant's understanding of this concept and Deleuze's attempt to overcome these limitations through the introduction of the notion of the Idea, which will provide a genetic and nonconceptual account of the object. In doing so, I show why Deleuze takes the formulation of an adequate account of difference to be one of the central aims of his own metaphysics. (shrink)

The article outlines a general epistemological theory of argument: a theory that regards providingjustified belief as the principal aim of argumentation, and defends it instrumentalistically. After introducing some central terms of such a theory (2), answers to its central questions are proposed: the primary object and structure of the theory (3), the function of arguments, which is to lead to justified belief (4), the way such arguments function, which is to guide the addressee's cognizing (5), objective versus subjective (...) aspects of argumentation (6), designing different types of argument (7). Then the notion of '(argumentatively) valid argument' is defined and criteria for the adequate use of such arguments are introduced (8). Finally, this conception is justified as, among others, leading to more true beliefs than competing conceptions (9). (shrink)

BackgroundRespect for autonomy is a key concept in contemporary bioethics and end-of-life ethics in particular. Despite this status, an individualistic interpretation of autonomy is being challenged from the perspective of different theoretical traditions. Many authors claim that the principle of respect for autonomy needs to be reconceptualised starting from a relational viewpoint. Along these lines, the notion of relational autonomy is attracting increasing attention in medical ethics. Yet, others argue that relational autonomy needs further clarification in order to be adequately (...) operationalised for medical practice. To this end, we examined the meaning, foundations, and uses of relational autonomy in the specific literature of end-of-life care ethics.MethodsUsing PRESS and PRISMA procedures, we conducted a systematic review of argument-based ethics publications in 8 major databases of biomedical, philosophy, and theology literature that focused on relational autonomy in end-of-life care. Full articles were screened. All included articles were critically appraised, and a synthesis was produced.ResultsFifty publications met our inclusion criteria. Twenty-eight articles were published in the last 5 years; publications were originating from 18 different countries. Results are organized according to: (a) an individualistic interpretation of autonomy; (b) critiques of this individualistic interpretation of autonomy; (c) relational autonomy as theoretically conceptualised; (d) relational autonomy as applied to clinical practice and moral judgment in end-of-life situations.ConclusionsThree main conclusions were reached. First, literature on relational autonomy tends to be more a ‘reaction against’ an individualistic interpretation of autonomy rather than be a positive concept itself. Dichotomic thinking can be overcome by a deeper development of the philosophical foundations of autonomy. Second, relational autonomy is a rich and complex concept, formulated in complementary ways from different philosophical sources. New dialogue among traditionally divergent standpoints will clarify the meaning. Third, our analysis stresses the need for dialogical developments in decision making in end-of-life situations. Integration of these three elements will likely lead to a clearer conceptualisation of relational autonomy in end-of-life care ethics. This should in turn lead to better decision-making in real-life situations. (shrink)

I criticize the particular argument for evolutionary progressivism which is based on the concept of a series of "dominant life forms." My procedure is to show that there is no rigorous definition for the concept of "dominant life form." I examine several attempts to define this concept by Julian Huxley and a new formulation of the concept by G. G. Simpson and show that none of the criteria either of these men develop for determining which groups of organisms can be (...) classified as dominant are adequate to exclude any groups of organisms from the classification. The concept proves so broad as to be meaningless. Since it is a key concept in the particular argument for progressivism that I discuss, the criticism of the concept demonstrates the argument to be invalid. (shrink)

In this paper, I discuss features of the interaction between a user and digital technology and how this transforms our contemporary experience of space and place. Analyzing this interaction is important for understanding global processes of displacement and creation of what Marc Augé calls non-places and their relation to technology in general. Drawing from Heidegger’s tool-analysis, I show that displacement is a structural element of the usage of absolutely ready-to-hand, access-providing digital devices. My main argument runs as follows: a) the (...) use of digital devices bypasses place directly in our activities; b) because of that, places themselves become more and more obsolete; and c) that leads to changes in how we conceive places and placefulness of technology. Instead, we think of the latter as immaterial, without a location. The immateriality of technology that we experience is reinforcing processes of displacement, as it allows them to continue thriving without being noticed and adequately conceptualized. (shrink)

A central theme throughout the impressive series of philosophical books and articles Stephen Toulmin has published since 1948 is the way in which assertions and opinions concerning all sorts of topics, brought up in everyday life or in academic research, can be rationally justified. Is there one universal system of norms, by which all sorts of arguments in all sorts of fields must be judged, or must each sort of argument be judged according to its own norms? In The (...) Uses of Argument Toulmin sets out his views on these questions for the first time. In spite of initial criticisms from logicians and fellow philosophers, The Uses of Argument has been an enduring source of inspiration and discussion to students of argumentation from all kinds of disciplinary background for more than forty years.

Formal models of argumentation have been investigated in several areas, from multi-agent systems and artificial intelligence (AI) to decision making, philosophy and law. In artificial intelligence, logic-based models have been the standard for the representation of argumentative reasoning. More recently, the standard logic-based models have been shown equivalent to standard connectionist models. This has created a new line of research where (i) neural networks can be used as a parallel computational model for argumentation and (ii) neural networks can be used (...) to combine argumentation, quantitative reasoning and statistical learning. At the same time, non-standard logic models of argumentation started to emerge. In this paper, we propose a connectionist cognitive model of argumentation that accounts for both standard and non-standard forms of argumentation. The model is shown to be an adequate framework for dealing with standard and non-standard argumentation, including joint-attacks, argument support, ordered attacks, disjunctive attacks, meta-level attacks, self-defeating attacks, argument accrual and uncertainty. We show that the neural cognitive approach offers an adequate way of modelling all of these different aspects of argumentation. We have applied the framework to the modelling of a public prosecution charging decision as part of a real legal decision making case study containing many of the above aspects of argumentation. The results show that the model can be a useful tool in the analysis of legal decision making, including the analysis of what-if questions and the analysis of alternative conclusions. The approach opens up two new perspectives in the short-term: the use of neural networks for computing prevailing arguments efficiently through the propagation in parallel of neuronal activations, and the use of the same networks to evolve the structure of the argumentation network through learning (e.g. to learn the strength of arguments from data).

Do not define argument by its use to persuade. for other uses of arguments exist. An argument is a proposition and a reason for it. and argumentation is an interchange involving two or more parties resulting in the assertion of one or more arguments coupled with anticipated or actual critical responses. A logically good argument has grounds adeq uate for the purposes at hand (true, probable, plausible, acceptable to the audience) and the grounds provide adequate support for (...) the conclusion. The norms for good logic in arguments are different from the norms for the good use of arguments. (shrink)

Too often in argumentation studies, an emphasis on argumentative norms fails to give adequate weight to elements of emotion and style that are essential to public speech at its best, not only in ordinary practice but especially in those rare moments where public speech arrives at the sublime. In this paper we examine the coordination of argument with figurative and emotive language whose combination yields sublime effects in the poetry of the Hebrew prophets as well as in examples of (...) modern discourse. It is shown that poetic figures, while not fully reducible to argumentative norms, nor rational in the sense commonly applied to argumentation, do in fact contribute in propriety in public discourse; moreover, they surpass mere propriety to generate moments of the sublime.

The view that argumentation is a desired reasoning practice in the classroom is well reported in the literature. Nonetheless, it is still not clear what type of reasoning supports classroom argumentation. The paper discusses abductive reasoning as the most adequate for students’ arguments to emerge in a classroom discussion. Abductive reasoning embraces the idea of plausibility and defeasibility of both the premises and the conclusion. As such, teachers’ role becomes the one of guiding students through formulating relevant hypotheses (...) and selecting the most plausible one according to criteria. Argumentation schemes are proposed as useful tools in this process.L'idée que l'argumentation est une pratique de raisonnement souhaitée en classe est bien documentée dans la littérature. Néanmoins, il n'est toujours pas clair quel type de raisonnement soutient l'argumentation en classe. Dans cet article on discute du raisonnement abductif comme étant le plus adéquat pour que les arguments des élèves émergent dans une discussion en classe. Le raisonnement abductif emploie l'idée de plausibilité et de la révocabilité des prémisses et de la conclusion. En tant que tel, le rôle des enseignants consiste à guider les élèves à formuler des hypothèses pertinentes et à sélectionner le plus plausible selon des critères. Les schèmes d'argumentation sont proposés comme des outils utiles dans ce processus. (shrink)

Stephen Toulmin once observed that ”it has never been customary for philosophers to pay much attention to the rhetoric of mathematical debate’ [Toulmin et al., 1979, An Introduction to Reasoning, Macmillan, London, p. 89]. Might the application of Toulmin’s layout of arguments to mathematics remedy this oversight? Toulmin’s critics fault the layout as requiring so much abstraction as to permit incompatible reconstructions. Mathematical proofs may indeed be represented by fundamentally distinct layouts. However, cases of genuine conflict characteristically reflect an (...) underlying disagreement about the nature of the proof in question. (shrink)

The central role played by Darwin's analogy between selection under domestication and that under nature has been adequately appreciated, but I have indicated how important the domesticated organisms also were to other elements of Darwin's theory of evolution-his recognition of “the constant principle of change,” for instance, of the imperfection of adaptation, and of the extent of variation in nature. The further development of his theory and its presentation to the public likewise hinged on frequent reference to domesticates.We have seen (...) that Darwin's reliance on the analogy between domesticated varieties and wild species was a bold and original step, in light of contemporary views on the nature of domesticates. However, as Darwin undoubtedly foresaw, his reliance on the analogy created difficulties as well as solving problems, and these began with his Malthusian codiscoverer of the principle of natural selection, Alfred Russel Wallace. Wallace's paper “On the Tendency of Varieties to Depart Indefinitely from the Original Type,” presented to the Linnean Scoiety along with the first public unveiling of Darwin's theory, states: We see, then, that no inferences as to varieties in a state of nature can be deduced from the observation of those occurring among domestic animals. The two are so much opposed to each other in every circumstance of their existence, that what applies to the one is almost sure not to apply to the other. Domestic animals are abnormal, irregular, artificial; they are subject to varieties which never occur and never can occur in a state of nature.62Much has been made of the similarity of views of Darwin and Wallace, but this quotation surely reveals how utterly different their views were on what to Darwin was an important matter. Several critics of the Origin saw Darwin's reliance on the domesticates as his Achilles heel. As Young has pointed out, Samuel Wilberforce included the following passage in his attack on the Origin: Nor must we pass over unnoticed the transference of the argument from the domesticated to the untamed animals. Assuming that man as the selector can do much in a limited time, Mr. Darwin argues that Nature, a more powerful, a more continuous power, working over vastly extended ranges of time, can do more. But why should Nature, so uniform and persistent in all her operations, tend in this instance to change? Why should she become a selector of varieties?63Another critic, Fleeming Jenkin, found the analogy a weakness in Darwin's theory because of the limited extent of variation in any one direction in domestic animals and plants.64 We have already seen that Darwin had confided a similar view to his notebook thirty years earlier, but changed his mind as a result of his profound study of domesticates. De Beer's reference to “an English country gentleman's knowledge of domestic plants and animals and their breeding”65 fails totally to recognize the originality and depth of Darwin's knowledge of domesticates.Why did Darwin, against the currents of his time, rely so heavily on mankind's experience with domesticated organisms to shape his theory about species in nature? On reason is that only with domesticates was an approach that came close to experimental verification possible. Darwin fully realized the inadequacies of the experiment, as is emphasized by his repeated contrasting of selection under nature and selection by man. Yet the extensive experience and data of plant and animal breeders offered the only reliable base against which Darwin could continually challenge his views. As he wrote in the introduction to Variation, with domestication, “man ... may be said to have been trying an experiment on a gigantic scale.”66 Given Darwin's high opinion of the quantitative work of Malthus and Quetelet (as emphasized by Schweber),67 and his unremitting efforts to secure data by which to test his theories, it was inevitable that he should attach high significance to domesticated varieties. John Tyndall, in his Belfast address of 1874, said: “The strength of the doctrine of Evolution consists, not in experimental demonstration (for the subject is hardly accessible to this mode of proof), but in its general harmony with scientific thought.”68 Darwin would have agreed with the latter thought, but I think he would have challenged the preceding one on the grounds that long experience with domesticated varieties did provide an element of experimental demonstration. It gave him confidence in his theory, and he used his vast knowledge of artificial selection boldly and creatively. (shrink)

The three research questions of this study have been: what exactly is active ambiguity?; how should we assess active ambiguities in an argumentative discussion?; what does an adequate dialectical account of active ambiguity look like? These three questions have been answered by giving a definition of active ambiguity, and by elaborating on the properties of active ambiguity. Based on the survey of possible consequences of active ambiguities, and based on the basic division of labour in a persuasion dialogue, we (...) arrived at a set of requirements that a normative, procedural account of active ambiguity should satisfy. The model for ambiguity dialectic both provides a detailed account of evaluating active ambiguities, as well as a dialectical account of dealing with alleged active ambiguity. The distinction between constitutive and regulative rules for discussion has made it possible to provide a discussion model in which discussants can raise the issue of active ambiguity, and in which they can argue about the correctness of such points of order. This immanent dialectical approach has lead to a fourfold classification of fallacies: by using an actively ambiguous expression a party either violates a regulative, or a constitutive rule for persuasion dialogue, and if this party violates a rule, he or she either commits a fallacy of ambiguity, and possibly also the more complex fallacy of equivocation. This model for ambiguity dialectic has been shown to be useful for the analysis and evaluation of complex debates and discussions. The present study can be extended in various ways:  A model for critical discussion can be enriched so that it accommodates other regulative rules, such as the rule that requires arguments to be valid. By doing so, other points of order and other fallacy criticisms can be studied from the perspective of a critical metadiscussion.  The results concerning active ambiguity can be applied to other modes of reasoning, such as visual argumentation.  The results can be applied to ambiguity at the level of larger stretches of argumentative discourse. That could lead to a fruitful contribution to the theory of argument structures.  There still is a need for dialectical models that concern the use of usage declaratives different from providing a disambiguation, such as the use of definitions, clarifications of unfamiliar expressions, amplifications, etc., and the question would have to be answered how the rules with respect to active ambiguity would relate to those models.  The model can be enriched by inserting a specific ‘linguistic utterance meaning testing machine’. That would be a major step towards implementing the model in a computer program.  The use of descriptive profiles of dialogue could be improved further. In order to analyse the way parties respond to dialectically complex contributions, we are in need of a dialectical theory that provides the parties with specific rights and obligations for putting forward complex contributions and for responding to complex contributions.

This paper challenges the view that arguments are (by definition, as it were) attempts to persuade or convince an audience to accept (or reject) a point of view by presenting reasons for (or against) that point of view. I maintain, first, that an arguer need not intend any effect beyond that of making it manifest to readers or hearers that there is a reason for doing some particular thing (e.g., for believing a certain proposition, or alternatively for rejecting it), (...) and second that when an arguer is in fact trying to induce an effect above and beyond rendering a reason manifest, the effect intended—the use to which his or her argument is put—need not be that hearers do what the stated reasons are reasons for doing. Where the actual or intended effect of making a reason R for doing X manifest is something other than doing X, I call it an oblique—as opposed to a direct—effect of making that reason manifest. The core of the paper presents an overview or map of the main categories of effect which arguments can have, and the main sub-types within each category, calling attention to the points at which such effects can be indirect or oblique effects. The purpose of that typology is to make it clear (i) how oblique effects can come about and (ii) how important a role they can play in the conduct of argumentation. (shrink)

The nature and value of what might be called formalism constitutes one of the recurrent themes in the history of logic. In each of the great ages of logic much the same pattern of events occurs. There is a period of discovery and development during which the formal element in logical relations is isolated and analysed for itself, and a science of logic is established. Although there may be doubt about the fringes of the subject, logicians at least are then (...) fairly well agreed on what constitutes formal logic. Someone next arises who compares this science of logic with the use of argument in every–day life and, finding it of little relevance, protests against what he considers its vain and useless formalism. Such in substance is the attitude of Cicero towards the ancient formal logic of Aristotle and the Stoics, and of the literary humanists of the Renaissance towards the logic of the late Middle Ages. Such, in brief, is the position of Prof. Toulmin towards the mathematical form of modern logic. (shrink)

This paper is to argue that conductive arguments could be understood from a rhetorical perspective. It contends that conductive arguments can be regarded as a particular mode of strategic maneuvering, rather than a new type of argument. Moreover, it demonstrates that the use of conductive arguments can be adequately analyzed and evaluated by adopting the theoretical tools developed in the extended Pragma-Dialectics.

The paper argues that there is good reason to doubt that virtue-based approaches to the question of justice can adequately come to grips with sophistic uses of the political lie – especially when sophistic thinking is stretched to the point of thoroughgoing moral skepticism, or well beyond that to outright moral nihilism and its cynical uses. To counter such uses, I turn to Kant’s most influential discussion of lying, which is found in his 1797article entitled “Of a Supposed Right to (...) Lie from Philanthropy.” Although I maintain that Kant’s particular moral argument against Constant is flawed, I argue that the specifically political position that Kant’s general juridical argument supports is sound. I thereby show how Kant’s account of the conditions for the possible conformity of politics with principles of right does effectively establish that an impeachable act of lying categorically requires impeachment and prosecution for wrongdoing. KEY WORDS – Kant. Moral philosophy. Fhilosophy of right. Political lie. (shrink)

Searching for a middle ground between psychologism and formalism, Toulmin argues that logic is the critical science or art of appraising arguments. Formal logic, by grounding itself upon an analytic conception of validity, is merely a reflection of the classical quest for certainty. But, Toulmin holds, in respect to actual arguments, which, in most fields, are substantial rather than analytic, such a conception is pointless and indicative of a fruitless and problem causing attitude toward the relation between theory (...) and practise.--C.

Arguments in natural theology have recently increased in their number and level of sophistication. However, there has not been much analysis of the ways in which these arguments should be evaluated as good, taken collectively or individually. After providing an overview of some proposed goals and good-making criteria for arguments in natural theology, we provide an analysis that stands as a corrective to some of the ill-formed standards that are currently in circulation. Specifically, our analysis focuses on (...) the relation between the veracity of the premises and their relation to the conclusion of an argument. In addition to providing a clearer account of what makes an argument good, an upshot of our account is that there remain positive contributions for "weak" arguments, especially within cumulative case arguments in ramified natural theology.

Toulmin’s formulation of “analytic arguments” in his 1958 book, The Uses of Argument, is opaque. Commentators have not adequately explicated this formulation, though Toulmin called it a “key” and “crucial” concept for his model of argument macrostructure. Toulmin’s principle “tests” for determining analytic arguments are problematic. Neither the “tautology test” nor the “verification test” straightforwardly indicates whether an argument is analytic or not. As such, Toulmin’s notion of analytic arguments might not represent such a key feature of (...) his model. Absent a clearer formulation of analytic arguments, readers of Toulmin should be hesitant to adopt this terminology. (shrink)

: The underdetermination argument establishes that scientists may use political values to guide inquiry, without providing criteria for distinguishing legitimate from illegitimate guidance. This paper supplies such criteria. Analysis of the confused arguments against value-laden science reveals the fundamental criterion of illegitimate guidance: when value judgments operate to drive inquiry to a predetermined conclusion. A case study of feminist research on divorce reveals numerous legitimate ways that values can guide science without violating this standard.

How can we assess the epistemic quality of democratic decision-making? Sceptics doubt such assessments are possible, as they must rely on controversial substantive standards of truth and rightness. Challenging that scepticism, this paper suggests a procedure-independent standard for assessing the epistemic quality of democratic decision-making by evaluating whether it is adequately supported by reasons. Adequate support for conclusion is a necessary aspect of epistemic quality for any epistemic justification of democracy, though particularly relevant to theories that emphasize public deliberation. (...) Finding existing methods for measuring the quality of public discourse to fall short, we draw on an epistemological theory of argumentation to provide a more sophisticated approach to evaluating the epistemic quality of democratic decision-making, illustrate how the approach can be used, and demonstrate its relevance for the epistemic turn in democratic theory.

The debate about experience-based or tacit knowledge has focused much attention on the limits to formalisation of work process knowledge. A main line of argument has been that, for example, industrial work even with highly advanced technical equipment can only be performed adequately when the worker through experience on the job has gained a feel for the functioning of the machinery and the properties and behaviour of the materials. In this debate links tend to be created between on the one (...) hand formalised-abstracted-verbal knowledge as opposed to on the other hand informalised-concrete-tacit knowledge. We have worked for some years with the design of training materials which at its core have video documentation of best practice as we have found it at work. In this paper we will present and discuss experience with design and use of a hypermedia type training material, SPRING to be used by new machine setters in the spring industry. Based on our own experience we will argue for the relevance of this type of training materials as a means of supporting reflection and dialogue in the community of practitioners. (shrink)

Many so-called “cognitivist” theories of the emotions account for the meaningfulness of emotions in terms of beliefs or judgments that are associated or identified with these emotions. In recent years, a number of analytic philosophers have argued against these theories by pointing out that the objects of emotions are sometimes meaningfully experienced before one can take a reflective stance toward them. Peter Goldie defends this point of view in his book The Emotions: A Philosophical Exploration. Goldie argues that emotions are (...) meaningful in a way that is different from the meaningfulness of beliefs. He describes this meaningfulness in terms of “feeling towards,” which he identifies as a unique type of intentionality characteristic of emotions. The independence of feeling-towards from acts like believing is most clearly brought out by cases in which there is not enough time to form a belief but in which a person experiencing feelings towards an object responds emotionally in a way that is meaningful to them. Employing a similar type of argument, the phenomenologist Max Scheler argues that certain types of acts of feeling are phenomenologically prior to presentative acts of perception, representation, or imagination. Scheler supports his claim about the phenomenological priority of such acts of feeling by referring to cases in which the presented contents of an object are hidden or obscured but where the object of feeling, value, remains adequately given. I endeavor to show how Scheler draws support for his position from these cases and the great significance of his interpretation of these cases for his philosophical outlook as a whole. I close by considering some questions about his interpretation and use of these cases. (shrink)

I argue that argumentation is not to be identified with (attempted) rational persuasion, because although rational persuasion appears to consist of arguments, some uses of arguments are not attempts at rational persuasion. However, the use of arguments in argumentative communication to try to persuade is one kind of attempt at rational persuasion. What makes it rational is that its informing ideal is to persuade on the basis of adequate grounds, grounds that make it reasonable and rational (...) to accept the claim at issue. (shrink)

BackgroundHealth data holds great potential for improved treatments. Big data research and machine learning models have been shown to hold great promise for improved diagnostics and treatment planning. The potential is tied, however, to the availability of personal health data. In recent years, it has been argued that data from health records should be available for health research, and that individuals have a duty to make the data available for such research. A central point of debate is whether such secondary (...) use of health data requires informed consent.Main bodyIn response to recent writings this paper argues that a requirement of informed consent for health record research must be upheld. It does so by exploring different contrasting notions of the duty of easy rescue and arguing that none of them entail aperfectduty to participate in health record research. In part because the costs of participation cannot be limited to 1) the threat of privacy breaches, but includes 2) the risk of reduced trust and 3) suboptimal treatment, 4) stigmatization and 5) medicalisation, 6) further stratification of solidarity and 7) increased inequality in access to treatment and medicine. And finally, it defends the requirement of informed consent by arguing that the mere possibility of consent bias provides a rather weak reason for making research participation mandatory, and that there are strong, independent reasons for making.ConclusionArguments from the duty of easy rescue in combination with claims about little risk of harm and potential consent bias fail to establish not only aperfectduty to participate in health record research, but also that participation in such research should be mandatory. On the contrary, an analysis of these arguments indicates that the duty to participate in research is most adequately construed as animperfectduty, and reveals a number of strong reasons for insisting that participation in health records research is based on informed consent.

This paper presents an analysis of the reasoning of two 5-year old children’s use of argument from definition. The author uses the Argumentum Model of Topics to accomplish this task. A brief history of the “locus of definition” is presented, as well as a description of how and where the data were collected. More specifically, the data come from a study of students conducted for over 30 years in Switzerland. Two examples are discussed where an adult experimenter examined these children’s (...) responses to conservation of liquid and number tasks. The two examples of children’s responses were analyzed using the locus from definition. Results show that children are capable of providing responses indicating their beliefs and support for them that are beyond Piaget’s description of a preoperational child’s reasoning abilities.

The chronicle of John of Worcester is one of the most important sources for earlier English history. Completed at Worcester by 1140, it is of considerable interest to historians of both the Anglo-Saxon period and the late eleventh and twelfth centuries. Its annals complement and add significantly to those in the surviving versions of the Anglo-Saxon Chronicle. It has never been adequately translated and a modern edition has long been needed. In this volume, Dr McGurk uses all the available manuscript (...) evidence, as well as the additions for 1122-41 made in a Gloucester continuation of a manuscript started in Johns own handwriting. Taken with these interpolations, the chronicle offers crucial evidence for the first five years of King Stephens reign. The Chronicle will be published in three volumes. Volume II covers the annals from 450 to 1066, and Volume III from 1067 to 1140. Volume I will be published last, and will contain a general introduction and supplementary material. (shrink)

The aim of the paper is to develop general criteria of argumentative validity and adequacy for probabilistic arguments on the basis of the epistemological approach to argumentation. In this approach, as in most other approaches to argumentation, proabilistic arguments have been neglected somewhat. Nonetheless, criteria for several special types of probabilistic arguments have been developed, in particular by Richard Feldman and Christoph Lumer. In the first part (sects. 2-5) the epistemological basis of probabilistic arguments is discussed. (...) With regard to the philosophical interpretation of probabilities a new subjectivist, epistemic interpretation is proposed, which identifies probabilities with tendencies of evidence (sect. 2). After drawing the conclusions of this interpretation with respect to the syntactic features of the probability concept, e.g. one variable referring to the data base (sect. 3), the justification of basic probabilities (priors) by judgements of relative frequency (sect. 4) and the justification of derivative probabilities by means of the probability calculus are explained (sect. 5). The core of the paper is the definition of '(argumentatively) valid derivative probabilistic arguments', which provides exact conditions for epistemically good probabilistic arguments, together with conditions for the adequate use of such arguments for the aim of rationally convincing an addressee (sect. 6). Finally, some measures for improving the applicability of probabilistic reasoning are proposed (sect. 7). (shrink)

Dharmottara, one of the most outstanding commentators of Dharmakīrti, re-uses arguments in the Pramāṇaviniścayaṭīkā, his broad commentary on Dharmakīrti’s Pramāṇaviniścaya, from his independent essay, the Kṣaṇabhaṅgasiddhi. By analyzing contents of re-used arguments in the Pramāṇaviniścayaṭīkā, this paper clarifies Dharmottara’s intention of paraphrasing his arguments in his commentarial work on Dharmakīrti. I argue that, in terms of content, such arguments are original and never fit into Dharmakīrti’s own system. It can be said that Dharmottara has a clear (...) intention to display his new innovations not only in his independent monograph, but also in his commentarial work. For Dharmottara, a commentary on Dharmakīrti is a better place than an independent monograph for showing off his advanced notions, since it is only in a commentary that his ideas can stand out directly against those of Dharmakīrti. In this sense, Dharmottara writes his commentary strategically. At the end of the article I discuss the significance of composing independent monographs or essays in the intellectual history of medieval India in the case of Dharmottara. (shrink)

This paper answers the question how pragmatic argumentation which occurs in a legal context, can be analyzed and evaluated adequately. First, the author surveys various ideas taken from argumentation theory and legal theory on the analysis and evaluation of pragmatic argumentation.

Finally she demonstrates how this instrument can be used by giving an exemplary analysis and evaluation of pragmatic (...) argumentation in a decision of the Dutch Supreme Court. (shrink)

One of the most fundamental questions in the philosophy of mathematics concerns the relation between truth and formal proof. The position according to which the two concepts are the same is called deflationism, and the opposing viewpoint substantialism. In an important result of mathematical logic, Kurt Gödel proved in his first incompleteness theorem that all consistent formal systems containing arithmetic include sentences that can neither be proved nor disproved within that system. However, such undecidable Gödel sentences can be established to (...) be true once we expand the formal system with Alfred Tarski s semantical theory of truth, as shown by Stewart Shapiro and Jeffrey Ketland in their semantical arguments for the substantiality of truth. According to them, in Gödel sentences we have an explicit case of true but unprovable sentences, and hence deflationism is refuted. -/- Against that, Neil Tennant has shown that instead of Tarskian truth we can expand the formal system with a soundness principle, according to which all provable sentences are assertable, and the assertability of Gödel sentences follows. This way, the relevant question is not whether we can establish the truth of Gödel sentences, but whether Tarskian truth is a more plausible expansion than a soundness principle. In this work I will argue that this problem is best approached once we think of mathematics as the full human phenomenon, and not just consisting of formal systems. When pre-formal mathematical thinking is included in our account, we see that Tarskian truth is in fact not an expansion at all. I claim that what proof is to formal mathematics, truth is to pre-formal thinking, and the Tarskian account of semantical truth mirrors this relation accurately. -/- However, the introduction of pre-formal mathematics is vulnerable to the deflationist counterargument that while existing in practice, pre-formal thinking could still be philosophically superfluous if it does not refer to anything objective. Against this, I argue that all truly deflationist philosophical theories lead to arbitrariness of mathematics. In all other philosophical accounts of mathematics there is room for a reference of the pre-formal mathematics, and the expansion of Tarkian truth can be made naturally. Hence, if we reject the arbitrariness of mathematics, I argue in this work, we must accept the substantiality of truth. Related subjects such as neo-Fregeanism will also be covered, and shown not to change the need for Tarskian truth. -/- The only remaining route for the deflationist is to change the underlying logic so that our formal languages can include their own truth predicates, which Tarski showed to be impossible for classical first-order languages. With such logics we would have no need to expand the formal systems, and the above argument would fail. From the alternative approaches, in this work I focus mostly on the Independence Friendly (IF) logic of Jaakko Hintikka and Gabriel Sandu. Hintikka has claimed that an IF language can include its own adequate truth predicate. I argue that while this is indeed the case, we cannot recognize the truth predicate as such within the same IF language, and the need for Tarskian truth remains. In addition to IF logic, also second-order logic and Saul Kripke s approach using Kleenean logic will be shown to fail in a similar fashion. (shrink)

In the debate concerning the education of nurses that is currently taking place in Denmark, two widely differing views are apparent regarding the best way of training nurses such that the ethical aspect of their work is adequately considered. The first of these is based on the premise that practical care is fundamental to and justified by theories on nursing, care and ethics, which is why the theoretical part of nurse education deserves a higher priority. The second view is based (...) on the premise that social care cannot be taught by means of theories, but can be learnt only through practice. The master-apprentice principle of ancient Greece is stressed in connection with this as being a viable alternative to the theoretical model of education. These two very different views can be traced back to Plato’s and Aristotle’s ideas on ethics and teaching respectively; indeed, those engaged in the debate make specific reference to these philosophers. In Denmark, a third fundamental viewpoint exists, known as ‘ontological ethics’. Phenomenologist KE Løgstrup is one of the best-known representatives of this view. Basing the line of argument on Løgstrup’s ethics and the view of education associated with this, this article questions the relevance of ancient Greek thought to today’s world by illustrating a number of problems that are connected with the theoretical model of nurse education and with the master-apprentice principle. Løgstrup associates ethics with the aesthetic principle that ‘the useless is the most useful’ in human life and with the view we also see in Kierkegaard’s and NFS Grundtvig’s writings that ethics can be imparted only by indirect means. Løgstrup bases his understanding of ethics on the Judaeo-Christian concept of Genesis and the view that human beings were created with an ethical potential that is best nourished by aesthetic impressions.

To adequately model mathematical arguments the analyst must be able to represent the mathematical objects under discussion and the relationships between them, as well as inferences drawn about these objects and relationships as the discourse unfolds. We introduce a framework with these properties, which has been used to analyse mathematical dialogues and expository texts. The framework can recover salient elements of discourse at, and within, the sentence level, as well as the way mathematical content connects to form larger argumentative (...) structures. We show how the framework might be used to support computational reasoning, and argue that it provides a more natural way to examine the process of proving theorems than do Lamport’s structured proofs.

Here I defend my solution to the wrong-kind-of-reason problem against Mark Schroeder’s criticisms. In doing so, I highlight an important difference between other accounts of reasons and my own. While others understand reasons as considerations that count in favor of attitudes, I understand reasons as considerations that bear (or are taken to bear) on questions. Thus, to relate reasons to attitudes, on my account, we must consider the relation between attitudes and questions. By considering that relation, we not only solve (...) the wrong-kind-of-reason problem, but we also bring into view rational agency—the use of reasons in thought. (shrink)

Why should one think Frege's definition of the ancestral correct? It can be proven to be extensionally correct, but the argument uses arithmetical induction, and that seems to undermine Frege's claim to have justified induction in purely logical terms. I discuss such circularity objections and then offer a new definition of the ancestral intended to be intensionally correct; its extensional correctness then follows without proof. This new definition can be proven equivalent to Frege's without any use of arithmetical induction. This (...) proves, without any use of arithmetical induction, that Frege's definition is extensionally correct and so answers the circularity objections. (shrink)

William of Ockham on the right to Use Goods Quintessentially medieval—an almost word-for-word refutation of an already prolix defense of several improbationes of earlier papal decrees—its greatest claim to fame has usually been its length, not the content of Ockham's argument. Annabel Brett, for example, concluded in a remarkable study that William of Ockham had failed to adequately answer Pope John XXII's criticism of the Michaelist interpretation of Franciscan poverty. Specifically, she argued that he "failed to isolate a potestas licita (...) which would be a power to perform acts which are licit in the sense of consonant with right reason, but are not strictly just." One could imagine the pope making the very same claim, but this would be to misunderstand Ockham's point. It is true that Ockham probably had little chance of convincing the pope of the coherence of his position. But this is not to say that his position was untenable.A common criticism of Ockham's theory of poverty is that he was, more or less, fighting on John XXII's own terms, which generally also leads to the conclusion that Ockham's theory is deficient in some respect. But if Ockham can be accused of fighting on the pope's ground because he responded to Quia vir reprobus point-by-point, then the pope can equally be accused of fighting on Michaelist ground because he was doing essentially the same thing. Alternatively, this claim might be interpreted as meaning that Ockham accepted as axiomatic certain claims of John XXII and then proceeded to construct an alternate theory to that of the pope's; consequently, this argument would continue, because Ockham could not get past certain foundational statements he was unable to properly address in the pope's claims. It is a corollary of the argument presented here that this was not the case.One of the paradoxes of the Franciscan modus vivendi was that, although their goal was to disengage from the civil order as far as all property relationships went, and despite the fact that Francis strongly commanded all brothers "through obedience" not to ask letters of the Roman curia, it quickly became necessary to have recourse to the papacy for all sorts of things. It is easy to see how this paradoxical relationship with the papacy could lead to trouble for the order, and indeed it was in the course of one of these appeals that the "Franciscan crisis under John XXII" might be said to have begun. The story, recounted by a Minorite who leaves no doubt as to his partisanship, is that when a Franciscan, Berengar Talon , defended a Beguin's view that Christ and his disciples possessed nothing, "either individually or in common, by right of ownership and lordship" against the Dominican inquisitor Jean de Beaune, the latter accused Berengar, too, of heresy. Not surprisingly, given the historical success of this method, Berengar appealed to the pope. As David Burr has said, "John reacted vigorously and, one suspects, enthusiastically." This time around, however, the pope was not so certain that the Franciscan position was the correct one. This appeal served as a pretext for re-opening the poverty "question," even if the ultimate motive for this move remain enigmatic.1 John XXII's Position on UseIf we must continue to guess at what prompted John to broaden his attack, one point jumps out from the first version of Ad conditorem canonum: of the three traditional monastic vows, poverty was the least important. The pope, probably following Hervaeus Natalis, was equally convinced that "the perfection of the Christian life consists principally and essentially in charity," and that.. (shrink)
