We present an algorithm that can anticipate tax evasion by modeling the co-evolution of tax schemes with auditing policies. Malicious tax non-compliance, or evasion, accounts for billions of lost revenue each year. Unfortunately when tax administrators change the tax laws or auditing procedures to eliminate known fraudulent schemes another potentially more profitable scheme takes it place. Modeling both the tax schemes and auditing policies within a single framework can therefore provide major advantages. In particular we can explore the likely forms (...) of tax schemes in response to changes in audit policies. This can serve as an early warning system to help focus enforcement efforts. In addition, the audit policies can be fine tuned to help improve tax scheme detection. We demonstrate our approach using the iBOB tax scheme and show it can capture the co-evolution between tax evasion and audit policy. Our experiments shows the expected oscillatory behavior of a biological co-evolving system. (shrink)

For Merleau-Ponty,consciousness in skillful coping is a matter of prereflective ‘I can’ and not explicit ‘I think that.’ The body unifies many domain-specific capacities. There exists a direct link between the perceived possibilities for action in the situation (‘affordances’) and the organism’s capacities. From Merleau-Ponty’s descriptions it is clear that in a flow of skillful actions, the leading ‘I can’ may change from moment to moment without explicit deliberation. How these transitions occur, however, is less clear. Given that Merleau-Ponty suggested (...) that a better understanding of the self-organization of brain and behavior is important, I will re-read his descriptions of skillful coping in the light of recent ideas on neurodynamics. Affective processes play a crucial role in evaluating the motivational significance of objects and contribute to the individual’s prereflective responsiveness to relevant affordances. (shrink)

In these lines from the fourth poem of his first collection of satires, Horace defines his poetic identity against the figures of his satiric predecessor Lucilius and his contemporary Stoic rival Crispinus. Horace emerges as the poet of Callimachean restraint and well-crafted writing in contrast to the chatty, unpolished prolixity of both Lucilius and Crispinus. A proponent of the highly wrought miniature over the sprawling scale of Lucilius, Horace knows when enough is enough. And, owing to a playful link between (...) what is satis and satura, this makes Horace not only a skilful poet but also the consummate satirist. I suggest that this programmatic message is both emphasized and illustrated by a piece of wordplay beginning in line 14. In a previously unnoticed telestich, the last letters of lines 14–18 spell out the word satis. Moreover, this hidden word—made possible only by the particular arrangement of words in all five of its lines—anticipates and deepens the poem's later interest in the matter of compositio, or artful word-arrangement. While this may be unique as an example of a Horatian telestich, Horace does engage in various forms of wordplay elsewhere, and could look not only to Hellenistic poets but also to Lucretius as a predecessor in this regard. In the Satires, a collection in which problems of libertas make forms of implication and veiled speech especially significant, a wide range of hidden words and wordplay has been detected and suggested. The instance observed here reaffirms Horace's interest in wordplay, while its uniqueness as a telestich is, as I hope to show, particularly suited to its context in this poem. (shrink)

Ruth Chang has defended a concept of "parity", implying that two items may be evaluatively comparable even though neither item is better than or equally good as the other. This article takes no stand on whether there actually are cases of parity. Its aim is only to make the hitherto somewhat obscure notion of parity more precise, by defining it in terms of the standard value relations. Given certain plausible assumptions, the suggested definiens is shown to state a necessary and (...) sufficient condition for parity, as this relation is envisaged by Chang. (shrink)

Proponents of permitting living kidney sales often argue as follows. Many jobs involve significant risks; people are and should be free to take these risks in exchange for money; the risks involved in giving up a kidney are no greater than the risks involved in acceptable hazardous jobs; so people should be free to give up a kidney for money, too. This paper examines this frequently invoked but rarely analysed analogy. Two objections are raised. First, it is far from clear (...) that kidney sales and dangerous jobs involve comparable risks on an appropriately broad comparison. Second, and more importantly, even if they do involve comparable risks it does not follow that kidney sales must be permitted because dangerous jobs are. The analogy assumes that kidney sales are banned for paternalistic reasons. But there may be other, non-paternalistic reasons for the ban. And paternalists, too, can consistently defend the ban even if kidney sales are no riskier than occupations that they find acceptable. Soft paternalists may want to protect would-be vendors from harms that they have not voluntarily chosen. Egalitarian hard paternalists may want to protect already badly off vendors from further worsening their situation. For neither species of paternalist is the size of the risk prevented decisive. I conclude that the analogy with dangerous jobs, while rhetorically powerful, pulls little real argumentative weight. Future debates on living kidney sales should therefore proceed without it.

This paper attempts to systematically characterize critical reactions in argumentative discourse, such as objections, critical questions, rebuttals, refutations, counterarguments, and fallacy charges, in order to contribute to the dialogical approach to argumentation. We shall make use of four parameters to characterize distinct types of critical reaction. First, a critical reaction has a focus, for example on the standpoint, or on another part of an argument. Second, critical reactions appeal to some kind of norm, argumentative or other. Third, they each have (...) a particular illocutionary force, which may include that of giving strategic advice to the other. Fourth, a critical reaction occurs at a particular level of dialogue (the ground level or some meta-level). The concepts here developed shall be applied to discussions of critical reactions by Aristotle and by some contemporary authors. (shrink)

Historians and biologists identify the debate between mechanists and vitalists over the nature of life itself with the arguments of Driesch, Loeb, and other prominent voices. But what if the conversation was broader and the consequences deeper for the field? Following the suspicions of Joseph Needham in the 1930s and Francis Crick in the 1960s, we deployed tools of the digital humanities to an old problem in the history of biology. We analyzed over 31,000 peer-reviewed scientific papers and learned that (...) bioexceptionalism participated in a robust discursive landscape throughout subfields of the life sciences, occupied even by otherwise unknown biologists.

We propose to understand social affordances in the broader context of responsiveness to a field of relevant affordances in general. This perspective clarifies our everyday ability to unreflectively switch between social and other affordances. Moreover, based on our experience with Deep Brain Stimulation for treating obsessive-compulsive disorder (OCD) patients, we suggest that psychiatric disorders may affect skilled intentionality, including responsiveness to social affordances.

The question of the existence of gravitational stress-energy in general relativity has exercised investigators in the field since the inception of the theory. Folklore has it that no adequate definition of a localized gravitational stress-energetic quantity can be given. Most arguments to that effect invoke one version or another of the Principle of Equivalence. I argue that not only are such arguments of necessity vague and hand-waving but, worse, are beside the point and do not address the heart of the (...) issue. Based on a novel analysis of what it may mean for one tensor to depend in the proper way on another, which, en passant, provides a precise characterization of the idea of a "geometric object", I prove that, under certain natural conditions, there can be no tensor whose interpretation could be that it represents gravitational stress-energy in general relativity. It follows that gravitational energy, such as it is in general relativity, is necessarily non-local. Along the way, I prove a result of some interest in own right about the structure of the associated jet bundles of the bundle of Lorentz metrics over spacetime. I conclude by showing that my results also imply that, under a few natural conditions, the Einstein field equation is the unique equation relating gravitational phenomena to spatiotemporal structure, and discuss how this relates to the non-localizability of gravitational stress-energy.

In a series of famous experiments, Benjamin Libet claimed to have shown that there is no scientific basis for our commonsensical understanding of freedom of the will. The actions we are about to undertake register in our brains before they register in our conscious minds. And yet, all that Libet may have shown is that long-invoked notions such as “the will” and “freedom” are poor explanations of how actions are initiated. Actions take place as we respond to the call of (...) the mood of the situation in which we find ourselves. Action is a way of attuning ourselves. Simple actions happen as long established habits kick in, and complex actions happen as the mood of a situation comes to correspond to the mood of a story we have been telling ourselves. When it feels right, we just act. (shrink)

An energy condition, in the context of a wide class of spacetime theories, is, crudely speaking, a relation one demands the stress-energy tensor of matter satisfy in order to try to capture the idea that "energy should be positive". The remarkable fact I will discuss in this paper is that such simple, general, almost trivial seeming propositions have profound and far-reaching import for our understanding of the structure of relativistic spacetimes. It is therefore especially surprising when one also learns that (...) we have no clear understanding of the nature of these conditions, what theoretical status they have with respect to fundamental physics, what epistemic status they may have, when we should and should not expect them to be satisfied, and even in many cases how they and their consequences should be interpreted physically. Or so I shall argue, by a detailed analysis of the technical and conceptual character of all the standard conditions used in physics today, including examination of their consequences and the circumstances in which they are believed to be violated.

In many contexts a retraction of commitment isfrowned upon. For instance, it is not appreciated,generally, if one withdraws a promise or denies anearlier statement. Critical discussion, too, caneasily be disrupted by retractions, if these occur toofrequently and at critical points. But on the otherhand, the very goal of critical discussion –resolution of a dispute – involves a retraction,either of doubt, or of some expressed point of view.A person who never retracts, not even under pressureof cogent arguments, would hardly qualify as (...) areasonable discussant. Also, inconsistencies in one'sposition, once they have been pointed out, must bedealt with by some kind of retraction. The problem ofretraction is to find a suitable model of dialoguethat allows retractions where they seem reasonable, oreven required, and rules them out (or puts sanctionsupon them) whenever they would become disruptive of awell-organized process of dialogue.The present paper tries to point to a solution basedon the following principles: (1) Retraction rulesdetermine what retractions are permissible, and (2) ifpermissible what the consequences of retraction are.(3) Retraction rules vary according to the type ofdialogue and (4) according to the type of commitmentretracted. For instance, assertions and mereconcessions need to be distinguished, as well aslight-side and dark-side commitments. (5) To accountfor our contradictory intuitions on the issue ofretractions, one may best resort to a complex type ofdialogue in which different retraction rules hold fordifferent parts.The paper explains, summarizes, and expands upon thediscussion of retraction in Commitment inDialogue by Douglas Walton and the present author(cf. Walton and Krabbe 1995). (shrink)

A ubiquitous argument against mental-state accounts of well-being is based on the notion that mental states like happiness and satisfaction simply cannot be measured. The purpose of this paper is to articulate and to assess this “argument from measurability.” My main thesis is that the argument fails: on the most charitable interpretation, it relies on the false proposition that measurement requires the existence of an observable ordering satisfying conditions like transitivity. The failure of the argument from measurability, however, does not (...) translate into a defense of mental-state accounts as accounts of well-being or of measures of happiness and satisfaction as measures of well-being. Indeed, I argue, the ubiquity of the argument from measurability may have obscured other, very real problems associated with mental-state accounts of well-being – above all, that happiness and satisfaction fail to track well-being – and with measures of happiness and satisfaction – above all, the tendency toward reification. I conclude that the central problem associated with the measurement of, e.g., happiness as a subjectively experienced mental state is not that it is too hard to measure, but rather that it is too easy to measure.

Negotiation is not only used to settle differences of interest but also to settle differences of opinion. Discussants who are unable to resolve their difference about the objective worth of a policy or action proposal may be willing to abandon their attempts to convince the other and search instead for a compromise that would, for each of them, though only a second choice yet be preferable to a lasting conflict. Our questions are: First, when is it sensible to enter into (...) negotiations and when would this be unwarranted or even fallacious? Second, what is the nature of a compromise? What does it mean to settle instead of resolve a difference of opinion, and what might be the dialectical consequences of mistaking a compromise for a substantial resolution? Our main aim is to contribute to the theory of argumentation within the context of negotiation and compromise formation and to show how arguing disputants can shift to negotiation in a dialectically virtuous way.

How should scarce healthcare resources be distributed? This is a contentious issue that became especially pressing during the pandemic. It is often emphasised that studies exploring public views about this question provide valuable input to the issue of healthcare priority setting. While there has been a vast number of such studies it is rarely articulated, more specifically, what the results from these studies would mean for the justification of principles for priority setting. On the one hand, it seems unreasonable that (...) public values would straightforwardly decide the ethical question of how resources should be distributed. On the other hand, in a democratic society, it seems equally unreasonable that they would be considered irrelevant for this question. In this paper we draw on the notion of reflective equilibrium and discuss the relevance and roles that empirical studies may plausibly have for justification in priority setting ethics. We develop a framework for analysing how different kinds of empirical results may have different kinds of implications for justification. (shrink)

I argue that an adequate semantics for physical theories must be grounded on an account of the way that a theory provides formal and conceptual resources appropriate for---that have propriety in---the construction of representations of the physical systems the theory purports to treat. I sketch a precise, rigorous definition of the required forms of propriety, and argue that semantic content accrues to scientific representations of physical systems primarily in virtue of the propriety of its resources. In particular, neither the adequacy (...) of those representations nor any referential relations their terms may enter into play any fundamental role in the determination of the representation's semantic content. One consequence is that anything like traditional Tarskian semantics is inadequate for the task. (shrink)

Intensive research is carried out to develop a disease-modifying drug for Alzheimer’s disease. The development of drug candidates that reduce Aß or tau in the brain seems particularly promising. However, these drugs target people at risk for AD, who must be identified before they have any, or only moderate, symptoms associated with the disease. There are different strategies that may be used to identify these individuals. Each of these strategies raises different ethical challenges. In this paper, we analyse these challenges (...) in relation to the risk stratification for AD necessary for using these drugs. We conclude that the new drugs must generate large health benefits for people at risk of developing AD to justify the ethical costs associated with current risk stratification methods, benefits much larger than current drug candidates have. This conclusion raises a new set of ethical questions that should be further discussed. No data are available. (shrink)

The purpose of this paper is to show the pervasive, though often implicit, role of arguments in negotiation dialogue. This holds even for negotiations that start from a difference of interest such as mere bargaining through offers and counteroffers. But it certainly holds for negotiations that try to settle a difference of opinion on policy issues. It will be demonstrated how a series of offers and counteroffers in a negotiation dialogue contains a reconstructible series of implicit persuasion dialogues. The paper (...) is a sequel to van Laar and Krabbe, in which we showed that for some differences of opinion it may be reasonable to shift from persuasion dialogue, aimed at a resolution of the difference on the merits, to negotiation dialogue, aimed at compromise, whereas in the present paper we show that such a shift need not amount to the abandonment of argumentation. Our main aim in this paper as well as in the previous one is to contribute to the theory of argumentation within the context of negotiation and compromise formation. (shrink)

Human consumption of pharmaceuticals often leads to environmental release of residues via urine and faeces, creating environmental and public health risks. Policy responses must consider the normative question how responsibilities for managing such risks, and costs and burdens associated with that management, should be distributed between actors. Recently, the Polluter Pays Principle (PPP) has been advanced as rationale for such distribution. While recognizing some advantages of PPP, we highlight important ethical and practical limitations with applying it in this context: PPP (...) gives ambiguous and arbitrary guidance due to difficulties in identifying the salient polluter. Moreover, when PPP does identify responsible actors, these may be unable to avoid or mitigate their contribution to the pollution, only able to avoid/mitigate it at excessive cost to themselves or others, or excusably ignorant of contributing. These limitations motivate a hybrid framework where PPP, which emphasizes holding those causing large-scale problems accountable, is balanced by the Ability to Pay Principle (APP), which emphasizes efficiently managing such problems. In this framework, improving wastewater treatment and distributing associated financial costs across water consumers or taxpayers stand out as promising responses to pharmaceutical pollution from human use. However, sound policy depends on empirical considerations requiring further study. (shrink)

In this paper I argue that there is an important distinction between past philosophers who are still sufficiently close to contemporary philosophy to have an actual significance on on-going philosophical research and such ones which are still relevant to modern problems in that we can recognize their questions and projects as ancestors of our own questions and projects. The class of the latter philosophical classics is fairly large, that of the former fairly restricted. I also argue that philosophers belonging to (...) the era before post-renaissance philosophy to a significantly lesser extent are even relevant to contemporary philosophical problems than those belonging to the post- Cartesian tradition. The last part of the paper is addressing the question whether philosophy can be said to make progress. I answer, with some hesitation, in the affirmative, while stressing that classical philosophers nevertheless can claim to as much greatness as more recent ones. I also make a point of accepting that solutions to philosophical problems is compatible with the existence of a manifold of solutions to one problem. It is also important to be aware that while some philosophical problems may be too deep to permit a solution, there are many middle-sized problems in philosophy that get a solution. (shrink)

A measure of coherence is said to be truth conducive if and only if a higher degree of coherence (as measured) results in a higher likelihood of truth. Recent impossibility results strongly indicate that there are no (non-trivial) probabilistic coherence measures that are truth conducive. Indeed, this holds even if truth conduciveness is understood in a weak ceteris paribus sense (Bovens & Hartmann, 2003, Bayesian epistemology. New York, Oxford: Oxford University Press; Olsson, 2005, Against coherence: Truth probability and justification. Oxford: (...) Oxford University Press). This raises the problem of how coherence could nonetheless be an epistemically important property. Our proposal is that coherence may be linked in a certain way to reliability. We define a measure of coherence to be reliability conducive if and only if a higher degree of coherence (as measured) results in a higher probability that the information sources are reliable. Restricting ourselves to the most basic case, we investigate which coherence measures in the literature are reliability conducive. It turns out that, while a number of measures fail to be reliability conducive, except possibly in a trivial and uninteresting sense, Shogenji’s measure and several measures generated by Douven and Meijs’s recipe are notable exceptions to this rule.

To give priority to the young over the elderly has been labelled ‘ageism’. People who express ‘ageist’ preferences may feel that, all else equal, an individual has greater right to enjoy additional life years the fewer life years he or she has already had. We shall refer to this as egalitarian ageism. They may also emphasise the greater expected duration of health benefits in young people that derives from their greater life expectancy. We may call this utilitarian ageism. Both these (...) forms of ageism were observed in an empirical study of social preferences in Australia. The study lends some support to the assumptions in the QALY approach that duration of benefits, and hence old age, should count in prioritising at the budget level in health care. (shrink)

Logical pluralism is commonly described as the view that there is more than one correct logic. It has been claimed that, in order for that view to be interesting, there has to be at least a potential for rivalry between the correct logics. This paper offers a detailed assessment of this suggestion. I argue that an interesting version of logical pluralism is hard, if not impossible, to achieve. I first outline an intuitive understanding of the notions of rivalry and correctness. (...) I then discuss a natural account of rivalry in terms of disagreement about validity claims and the argument from meaning variance that has been raised against it. I explore a more refined picture of the meaning of validity claims that makes use of the character-content distinction of classical two dimensional semantics. There are three ways in which pluralists can use that framework to argue for the view that different logics may be rivals but could nevertheless be equally correct. I argue that none of them is convincing. (shrink)

In identifying himself with language, the speaking man places his own muteness outside of himself, as already and not yet human. There is, perhaps, something barbarous in the assumption of the word. In the ontological equation that aligns the speaking being with the human being there may abide a gesture that can be neither heard nor interpreted. With the logos that we inherit “by nature” and then “by right,” according to Agamben, the cut between the human and the animal is (...) made without a sound and undertaken in the name of excising that silence in which it is possible to ask after the ethical violence that attends the constitution of “humanity’s” language and the promise of language’s ..

This issue of Philosophy & Rhetoric, a somewhat rare double-issue, features significant and inspiring work that moves in a variety of directions and proceeds in a number of idioms, while also responding directly and indirectly to a complex exigence, though perhaps in a less familiar sense of the term, as what Giorgio Agamben calls a “messianic modality” that “coincides with the possibility of philosophy itself”—exigency as the expression of what remains unforgettable in the midst of all that is no longer (...) remembered for the sake of history’s progress. Appearing between contingency and necessity, exigency is not then a problem to be re-solved but the opening of a question; or more precisely, the epideictic expression of question-ability, the beginning of inquiry into what calls forth and perhaps even demands its possibility, for now.On what grounds do old questions stand? Through what power and by what happenstance are new questions found and formed? And when—in what kinds of moments do questions appear? With what force do they arrive? At what cost? What questions inflict violence? What violence thwarts a question? What do we (not) ask? How does the (un)questionable give way? Can multiple disciplines ever pose let alone inquire into the same question? What are the (de)constitutive elements of a good question? What does a good question do? Has pious genealogy corrupted the question? Does the discovery of a question remain one of the last “secrets,” the unhinged authentic insight about which little can or should be said?A century ago, announcing the launch of Angelus Novus, Benjamin reflected on the moment and contended that the “vocation of a journal is to proclaim the spirit of its age.” Such a task, in his view, demanded a strict “relevance to the present” even over “unity or clarity” and required exposing the “talented fakes” and resisting “the sterile pageant of new and fashionable events” that obscure how “impossible it is in our age to give a voice to any communality [Gemeinsamkeit].” It is a tall and certainly debatable order, one that Benjamin himself was unable to realize—Angelus never got off the ground. But perhaps the underlying insight remains, the basic importance of holding space for work that discerns and expresses the potential of question-ability.This potential may well be the spirit-breath of an age. And, for now, here and now, it may well be a pressing question—on the shore of Ontario’s Crawford Lake, waiting for official word that the Holocene has ended; in a largely unacknowledged transition, seemingly out of the pandemic’s worst, ramping back up to speed, and yet deeply uncertain about the next normal; in the midst of the two “wars” (a term to which all participating parties will not agree) that make the front page (or the top of the feed) and the many that do not, the grotesque surfeit of increasingly automatic-droning violence unfolding on the grounds of sanctified rage that makes it difficult to ask let alone grasp what violence is; at the gates of the university, where so much inquiry is supplanted with so many strategic plans, and academic freedom is slowly juridified to the advantage of legislatures eager to rewrite the mission; and, in the midst of the noisy quietude that thwarts so many of the small inquiries into well-being that weave the fabric of public life.It’s been a pleasure to work with all of those who have contributed to this issue of Philosophy & Rhetoric. Indeed, the pages that follow radiate with curiosity and insight. Together, they are an expression of inquiry in which question-ability remains unforgettable and there remains a moment to ask—after the question. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:For Today, There Will Be a Speech (and a Song) TomorrowErik DoxtaderFor we see that things that are going to be take their start from deliberating and from acting, and equally that there is in general a possibility of being and not being in things that are not always actual. In them, both are open, both being and not being, and so also both becoming and not becoming. And (...) plenty of things are obviously like this.—Aristotle, De Interpretatione, IX*Wish again, four times again Four wishes deep into the well There's a price to pay for a wish to come true Trade a small piece of your life Roots in soil, uprooting the soil Mountain high, high mountain. The wish is only to speak a kind—Bob Mould, “Wishing Well”This is the time Because there is no time—Lou Reed, “There Is No Time” [End Page 311]The potential of rhetorical culture abides. In the subtle last lines of Norms of Rhetorical Culture, Tom Farrell imbued this potential with the aura of a (double) wish: when read with a forgiving spirit, the value of the “classical rhetorical tradition” appears in its capacity to “restore the power and resilience of the wish in the thought and expression of our civic life” (1993, 320). From within the history of our (not) being together, there are rhetorical goods to (be)come.Wishes must be made. Today, if it is not to betray the fact that a “rhetorical culture is something that must be cultivated,” our inheritance of rhetoric's potential is not a matter of fate. Far from given, although perhaps a gift that speaks volumes about our humanity, its appearance hinges on a choice to “uncover and engender new sources of creative reason” and to do so together, with an appreciation that this shared work is “unmistakably of ethical, aesthetic, and normative significance” (Farrell 1993, 11, 3). Confronted with such a task, as Farrell stressed again and again, “The question is how? How are we to find and develop the capacities that warrant and establish rhetorical study?” (1993, 65). And, from a theoretical and practical perspective, how can we struggle meaningfully with “our own nature as rhetorical creatures: an undiminished capacity to engage limitation through imagination, to find moral content in the experience of the other as audience, and wisdom through the collective production and enactment of logos ” (Farrell 1990, 83)? The rhetorical impulse coincides with the exigency of human experience that remains forgotten and yet unforgettable.1Knocking on modernity's door, Tom Farrell was deeply concerned with rhetoric's manifold potential. Over the course of a prolific career, he pursued the matter with passion, rigor, and integrity. He asked his colleagues, his students, and indeed his discipline to question conventional wisdom about the terms and power of rhetorical theory; interested in both everyday and extraordinary rhetorical practices, Farrell's criticism helped a field to see why its work counted as a vocation at the same time that he reached over the academy's walls in order to suggest that so-called mere rhetoric was quite a bit more complicated and much more important than perhaps some cared to admit. That his vision was compelling is evidenced not least by the numerous awards that he received for his work and the ways in which it continues to inform and shape critical thinking about the art of rhetoric.Just over two years after Tom's unfortunate and tremendously saddening death, this issue of Philosophy and Rhetoric pays tribute to his ground breaking work. Yet, as Farrell himself suspected, the risk that unbridled praise is the short road to bad infinity's silence brings the need for something more. Today, a consideration of his thought and writing demands a space [End Page 312] for critical reflection with practical significance, a forum—in Farrell's sense of the term—that affords an opportunity to ask both whether and how we might understand, extend, and indeed challenge Farrell's contention that rhetoric is the “collaborative manner of engaging others through discourse so that contingencies may be resolved, judgments rendered, action produced” (1990, 83). To these ends, this issue of the... (shrink)

This paper explores applications of concepts from argumentation theory to mathematical proofs. Note is taken of the various contexts in which proofs occur and of the various objectives they may serve. Examples of strategic maneuvering are discussed when surveying, in proofs, the four stages of argumentation distinguished by pragma-dialectics. Derailments of strategies (fallacies) are seen to encompass more than logical fallacies and to occur both in alleged proofs that are completely out of bounds and in alleged proofs that are at (...) least mathematical arguments. These considerations lead to a dialectical and rhetorical view of proofs. (shrink)

Our understanding of the cognitive processes involved in reading has been advanced by computational models that simulate those processes. Unfortunately, most of these models have been developed to explain the reading of English and other alphabetic languages, with relatively fewer efforts to examine whether or not the assumptions of these models also explain what has been learned from other languages and, in particular, non-alphabetic writing systems like Chinese. In this article, we will review those computational models that have been developed (...) to explain the reading of Chinese, with the goal of comparing their theoretical assumptions to those of models that explain the reading of English. Our analysis indicates that there are both points of convergence and divergence between the theoretical assumptions of Chinese versus English models, suggesting that the cognitive systems supporting reading may be differentially influenced by features of the languages and/or writing systems, or that certain theoretical assumptions developed to explain the reading of one language might be adapted to explain the reading of others.

Critical Gaming: Interactive History and Virtual Heritage can be seen as a collection of chapters designed to provoke thought and discussion, or it can be seen and used as separate chapters that may help class debate in courses dealing with the digital humanities, game studies (especially in the areas of serious games and game-based learning) or aspects of virtual heritage. While there are very few books in this intersecting area, the range of topics that could be investigated and debated is (...) huge. So instead I have concentrated on questions in areas that appear to be central to the intersection of these three areas, have not currently been debated to any great extent or are topics that would suit either individual reflection or classroom discussion and debate.

Stuart White argues that egalitarians need a diverse toolkit of policy proposals in order to move closer to a just economic system. In particular he argues that a policy of Basic Capital grants should be included in this toolkit along with a variety of other more familiar instruments such as unconditional Basic Income, welfare state services and income supports, and support for worker cooperatives. The various policies in the egalitarian toolkit, however, have implications for issues other than contributing to a (...) more just economic system. In particular, they have implications for the long term stability, transformation, or even transcendence, of capitalism as an economic system. In this article I will argue that unconditional Basic Income has a greater potential to erode capitalism than does Basic Capital. While both of these policies in the egalitarian toolkit may make the economic system statically more just, over time Basic Capital grants are likely to strengthen capitalism as the core structure of the economic system, whereas unconditional Basic Income has the potential to erode the dominance of capitalism. As part of a long-term project of human emancipation, therefore, unconditional Basic Income should have priority over Basic Capital. (shrink)

Criticism may degenerate into quibbling or nitpicking. How can discussants keep quibblers under control? In the paper we investigate cases in which a battle about words replaces a discussion of the matters that are actually at issue as well as cases in which a battle about minor objections replaces a discussion of the major issues. We survey some lines of discussion dealing with these situations in profiles of dialogue.

This paper discusses several types of relevance criticism within dialogue. Relevance criticism is a way one could or should criticize one's partner's contribution in a conversation as being deficient in respect of conversational coherence. The first section tries to narrow down the scope of the subject to manageable proportions. Attention is given to the distinction between criticism of alleged fallacies within dialogue and such criticism as pertains to argumentative texts. Within dialogue one may distigguish tenability criticism, connection criticism, and narrow-type (...) relevance criticism. Only the last of these three types of criticism constitutes a charge of fallacy and carries with it a burden of proof. In the second it is observed that a full study of narrow-type relevance criticism would require the construction of complicated, many-layered, dialogue systems. Such a study can, however, be profitably preceded by setting up profiles of dialogue that help us discuss the ins and outs of certain types of move. This is illustrated with an example. (shrink)

The dispute over the viability of various theories of relativistic, dissipative fluids is analyzed. The focus of the dispute is identified as the question of determining what it means for a theory to be applicable to a given type of physical system under given conditions. The idea of a physical theory's regime of propriety is introduced, in an attempt to clarify the issue, along with the construction of a formal model trying to make the idea precise. This construction involves a (...) novel generalization of the idea of a field on spacetime, as well as a novel method of approximating the solutions to partial-differential equations on relativistic spacetimes in a way that tries to account for the peculiar needs of the interface between the exact structures of mathematical physics and the inexact data of experimental physics in a relativistically invariant way. It is argued, on the basis of these constructions, that the idea of a regime of propriety plays a central role in attempts to understand the semantical relations between theoretical and experimental knowledge of the physical world in general, and in particular in attempts to explain what it may mean to claim that a physical theory models or represents a kind of physical system. This discussion necessitates an examination of the initial-value formulation of the partial-differential equations of mathematical physics, which suggests a natural set of conditions---by no means meant to be canonical or exhaustive---one may require a mathematical structure, in conjunction with a set of physical postulates, satisfy in order to count as a physical theory. Based on the novel approximating methods developed for solving partial-differential equations on a relativistic spacetime by finite-difference methods, a technical result concerning a peculiar form of theoretical under-determination is proved, along with a technical result purporting to demonstrate a necessary condition for the self-consistency of a physical theory.

We argue that people may resist temptations not only with the aim of acquiring more self-control, but also because they want to convince others that they are patient and already possess self-control.

In the present paper it is argued that genetic interventions on human embryos are in principle permissible if they promote the health of the persons that these embryos will one day become and impermissible if they compromise their health. This so called health-intervention principle is reached by, inter alia, rejecting alternative approaches to the problem of the permissibility of genetic intervention. The health-intervention principle can be interpreted in different ways depending on how the notion of health is understood. The central (...) part of the paper is an attempt to find a concept of health which is such that it makes the health-intervention principle normatively plausible. For this purpose I examine two influential competing theories of health: Cristopher Boorse’s biostatistical theory of health and Lennart Nordenfelt’s welfare theory of health. I argue that the health-intervention principle is more plausible if health is understood in the latter sense, although it is not ruled out that the principle may be given an even more plausible explication in terms of some other notion of health.

Families of types are fundamental objects in Martin-Löf type theory. When extending the notion of setoid (type with an equivalence relation) to families of setoids, a choice between proof-relevant or proof-irrelevant indexing appears. It is shown that a family of types may be canonically extended to a proof-relevant family of setoids via the identity types, but that such a family is in general proof-irrelevant if, and only if, the proof-objects of identity types are unique. A similar result is shown for (...) fibre representations of families. The ubiquitous role of proof-irrelevant families is discussed. (shrink)

This book philosophically and creatively examines ways in which independent filmmakers may explore, through practice, the discovery and development of a personal voice in the making of their films. Filmmaker and academic, Professor Erik Knudsen, uses a combination of autoethnographic experience derived from his own filmmaking practice and new insights gained from a series of ethnomediaological StoryLab workshops with independent filmmakers in Malaysia, Ghana and Colombia to drive this innovative examination. The book contextualises this practice exploration within an eclectic (...) pschological and philosophical framework that ranges from Jungian psychological theories of the collective unconscious to Sheldrakian scientific theories of morphic resonance, from Christian mystical ideas about creative motivation to structuralist theories that underpin our linguistic understanding of story and narrative. Why should we create? What is a creative act? This in-depth study tackles these questions by examining the early ideation stages of cinematic expression and ultimately seeks to understand the practical ways in which ideas are shaped into stories and narratives"--Back cover.

“In When Your Life Is On Fire Erik Kolbell listens, provokes, and most of all, shares with us the enduring lessons and insights of life and faith as realized by a diverse population of thoughtful people. It’s a town hall of the soul.” -- Tom Brokaw If your life was on fire, what would be the one thing you save? Psychotherapist and former pastor Erik Kolbell asks that question of 13 remarkable and unique individuals, and the answers may (...) surprise you. Provided by celebrities such as Jane Pauley and Alan Alda, artists such as Regina Carter and Tao Porchon Lynch, and ordinary people put into extraordinary situations like Don Lange and Brenda Berkman, these reflections will help all of us consider what it is that we value most in life. His goal, Kolbell says, is not to examine the worth of each of these things. “What matters is that for all of the sham and artifice that can make cynics of us all, there are things, solid things, that compel us onward.”.

In a just society, who should be liable for the significant costs associated with creating and raising children? Patrick Tomlin has recently argued that children themselves may be liable on the grounds that they benefit from being raised into independent adults. This view, which Tomlin calls ‘Kids Pay’, depends on the more general principle that a beneficiary can incur an obligation to share in the cost of an essential benefit that the benefactor is responsible for her requiring. I argue in (...) this paper that this principle is both generally false and particularly suspect in the kinds of cases that Tomlin needs it to be true, namely, cases in which a benefactor has created the need to be benefitted to satisfy a self-regarding interest in providing the benefit. In a nutshell, I argue that because parents electively put their children into a needy circumstance for the purpose of satisfying a self-regarding interest in meeting their children’s needs, they lack a legitimate claim against their children to share in its associated costs.

I publish here two letters by the French philosopher and mathematician René Descartes. The first and most important letter, dating from May 1641 and addressed to Mersenne, is almost entirely devoted to the printing of the Meditations in Paris. The second letter, dated June 1646, is Descartes' letter of thanks to Pasor, rector of the University of Groningen, after receiving satisfaction for the complaints he had filed against Schoock. The text of both letters was unknown.

Systems of formal dialectics articulate methods of conflict resolution. To this end they provide norms to regulate verbal exchanges between the Proponent of a thesis and an Opponent. These regulated exchanges constitute what are known as formal discussions.One may ask what moves, if any, in formal discusions correspond to arguing for or against the thesis. It is claimed that certain moves of the Proponent's are properly designated as arguing for the thesis, and that certain moves of the Opponent purport to (...) criticize the tenability or the relevance of the reasons advanced. Thus the usefulness of formal dialectic systems as models for reasonable argument is vindicated.It is then proposed to make these systems more realistic by incorporating in them a norm of Creative Reasoning that removes the severe restrictions to which the Proponent's arguing was hitherto subject. As a consequence, a certain type of irrelevant reason is no longer automatically excluded. Therefore, it is proposed to extend the Opponent's rights to exert relevance criticism. The new dialectic systems are shown to be strategically equivalent to the original ones. Finally, it is stressed that the Opponent's criticism should not be designated as arguing against the thesis. The Opponent criticizes, but does not argue. (shrink)

Can appealing to children’s rights help to solve the non-identity problem in cases of procreation? A number of philosophers have answered affirmatively, arguing that even if children cannot be harmed by being born into disadvantaged conditions, they may nevertheless be wronged if those conditions fail to meet a minimal standard of decency to which all children are putatively entitled. This paper defends the tenability of this view by outlining and responding to five prominent objections that have been raised against it (...) in the contemporary literature: the identifiability objection; the non-existence objection; the waiving of rights objection, the lack of legitimate complaint objection; and the unfairness objection.

The recent literature on genocide shows signs of taking what might be called a “processual turn,” with genocide increasingly understood as a contingent process rather than a singular event. But while this second generation's turn may be clear to those within the literature, the theory guiding the change is insufficiently specified. The theory regarding process and contingency is implicit, and, as such, genocide theory does not realize its full generative potential. The primary goal of this article is to provide a (...) more robust theoretical framework for making sense of the continually evolving dimensions of genocide. It builds on the literature's existing foundations, most notably Mann's (2005) notion of “contingent escalations.” In the spirit of the recent revival of American Pragmatism in sociology, it draws on the work of Dewey, Mills, Follett, and Addams (among others) as part of a theoretical reconstruction using pragmatist concepts such as rupture, perplexity, vocabularies of motive, and experimentation to consider examples from the Rwandan genocide and show how we might explore the potential for non-teleological intentionality on the part of genocidal actors. The result is an enhanced theoretical framework that offers “fresh eyes” for considering one of the worst (and most under-theorized) social problems. (shrink)

In this article, I want to make the following points, none of which are totally new, but their constellation here is meant to be challenging. First, world is not a thing but an event, the event of sense. This event is opening and meaning – verbal tense. God may be a philosophical name of this event. This is recognized by late-modern religious atheist thought. This thought differs from modern scientific rationalism in that the latter’s so-called areligious atheism is actually a (...) hyperreligious theism. On the way, the alleged opposition between philosophy and theology, between thought and faith is seen to erode. The core matter of this philosophy of religion will be the absolute reference, the system of objectivity and the holiness of the name. All this because of a prefix a- that has its sense turned inside out by the death of God. (shrink)

For more than 20 years, sustainable development has been advocated as a way of tackling growing global environmental and social problems. The sustainable development discourse has always had a strong technological component and the literature boasts an enormous amount of debate on which technologies should be developed and employed and how this can most efficiently be done. The mainstream discourse in sustainable development argues for an eco-efficiency approach in which a technology push strategy boosts efficiency levels by a factor 10 (...) and more in industrialised and developing countries. A minority argues for a socio-cultural lifestyle switch, relying on new values, quality of life, sufficiency and redistribution strategies, with calls for appropriate and soft technologies. It is remarkable, however, that the articles, books and policy debates on sustainability seldom explicitly draw in a discussion of the nature of technology, how technology influences and is influenced by society, and what this implies for sustainable development. The mainstream interprets technology as neutral and instrumental: technology is no more than an instrument to reach a goal; it cannot be judged on its intrinsic characteristics, only on its use. The alternative view often builds on an autonomous and substantive interpretation of technology: technology is an autonomous, almost uncontrollable power that fundamentally reshapes our culture. A more balanced approach seems to be growing in the research on socio-technical sustainability transitions where the focus shifts to the co-evolution of technology and society, and to the networks, seamless webs and complex multi-actor processes that may carry a sustainability transition forward. This approach builds on insights from recent traditions in the philosophy and sociology of technology, in particular the social construction of technology (SCOT) and actor-network theory (ANT). While this provides for a better understanding of the nature and potential role of technology in sustainability policies, it remains to be seen whether it will actually influence the choice between technologies. This article investigates the different conceptualisations of technology in the sustainability debate. It first distinguishes between different approaches of sustainability and how these are related to differing views on technology. It then moves on to how the socio-technical transitions research incorporates insights from contemporary philosophy and sociology of technology. It reflects on the potential of transitions research to give guidance in technology choices, suggesting that the transition approach might be strengthened by drawing in insights from critical theory of technology and by taking a more political stance in defining sustainable development.

Maintaining systems of military plans is critical for military effectiveness, but is also challenging. Plans will become obsolete as the world diverges from the assumptions on which they rest. If too many ad hoc changes are made to intermeshed plans, the ensemble may no longer lead to well-synchronized and coordinated operations, resulting in the system of plans becoming itself incoherent. We describe in what follows an Adaptive Planning process that we are developing on behalf of the Air Force Research Laboratory (...) (Rome) with the goal of addressing problems of these sorts through cyclical collaborative plan review and maintenance. The interactions of world state, blue force status and associated plans are too complex for manual adaptive processes, and computer-aided plan review and maintenance is thus indispensable. We argue that appropriate semantic technology can 1) provide richer representation of plan-related data and semantics, 2) allow for flexible, non-disruptive, agile, scalable, and coordinated changes in plans, and 3) support more intelligent analytical querying of plan-related data.

Even though the philosophy of common sense is not justifi able as such, the assump- tion upon which it rests, namely that there are things which we are not in position to doubt is correct. The reason why Thomas Reid was unable to bring this assumption out in a justifi able manner is that his views, both on knowledge and nature, are to be considered dogmatic. American pragmatists such as Charles Sanders Peirce and John Dewey on the other hand, may (...) be seen as offering us a ‘critical’ and post-Darwinian philosophy of common sense. (shrink)

Argumentative discussion is successful only if, at the concluding stage, both parties can agree about the result of their enterprise. If they can not, the whole discussion threatens to start all over again. Dialectical ruling should prevent this from happening. The paper investigates whether dialectical rules may enforce a decision one way or the other; either by recognizing some arguments as conclusive or some criticisms as devastating. At the end the pragma-dialectical model appears more successful than even its protagonists have (...) claimed. (shrink)

The notion of epistemic standards has gained prominence in the literature on the semantics of knowledge ascriptions. Defenders of Epistemic Contextualism claim that in certain scenarios the truth value of a knowledge-ascribing sentence of the form “S knows p (at t)”—where S is an epistemic subject and p is a proposition S is said to know at time t—can change even if S, p and t are assigned constant values. This sort of variability, contextualists claim, is due to the epistemic (...) standards governing the context in which the knowledge ascription is uttered. While a specific knowledge ascription may be true when uttered in a context with “low” epistemic standards, it may be false when uttered in a context with “high” epistemic standards. The reason for this, as far as contextualists are concerned, is the context sensitivity of the verb “knows”. In standard semantics an expression is said to be context sensitive if and only if it expresses different contents (or intensions) relative to different contexts of utterance. Thus, as epistemic standards influence the content of “knows”, they play a crucial role in contextualist semantics. In this paper, I examine different conceptions of epistemic standards and argue that all but one lead to counterintuitive consequences. The conception which avoids these consequences, however, has the downside of seriously restricting the talk of “high” or “low” standards that is so frequent in discussions on the semantics of knowledge ascriptions.
