Default logic has been a very active research topic in artificial intelligence since the early 1980s, but has not received as much attention in the philosophical literature thus far. This paper shows one way in which the technical tools of artificial intelligence can be applied in contemporary epistemology by modeling a paradigmatic case of deep disagreement using default logic. In §1 model-building viewed as a kind of philosophical progress is briefly motivated, while §2 introduces the case of (...) class='Hi'>deep disagreement we aim to model. On the heels of this, §3 defines our formal framework, viz., a refined Horty-style default logic. §4 then uses the framework to model deep disagreement, and finally §5 provides a critical discussion of the result.

Disagreements that resist rational resolution, often termed “deep disagreements”, have been the focus of much work in epistemology and informal logic. In this paper, I argue that they also deserve the attention of philosophers of mathematics. I link the question of whether there can be deep disagreements in mathematics to a more familiar debate over whether there can be revolutions in mathematics. I propose an affirmative answer to both questions, using the controversy over Shinichi Mochizuki’s work on the (...) abc conjecture as a potential example of both phenomena. I conclude by investigating the prospects for the resolution of mathematical deep disagreements in virtue-theoretic approaches to informal logic and mathematical practice. (shrink)

Why is it that some instances of disagreement appear to be so intractable? And what is the appropriate way to handle such disagreements, especially concerning matters about which there are important practical and political needs for us to come to a consensus? In this paper, I consider an explanation of the apparent intractability of deep disagreement offered by hinge epistemology. According to this explanation, at least some deep disagreements are rationally unresolvable because they concern ‘hinge’ commitments (...) that are unresponsive to rational considerations. This explanation, if correct, seems to have troubling implications for how we should respond to deep disagreement. If my position on a topic is not responsive to rational considerations, then what choice have I but to dogmatically hold to that position, and simply dismiss the views of those with whom I disagree? I address this problem by identifying an attitude of intellectual humility that is appropriate to have towards one's hinge commitments, and suggest that this attitude provides the basis for a non-rational, constructive way to resolve deep disagreement.

Deep disagreements are characteristically resistant to rational resolution. This paper explores the contribution a virtue theoretic approach to argumentation can make towards settling the practical matter of what to do when confronted with apparent deep disagreement, with particular attention to the virtue of courage.

This article starts off with a historical section showing that deep disagreements among notions of social and political justice are a characteristic feature of the history of political thought. Since no agreement or consensus on distributive justice is possible, the article argues that political philosophers should – instead of continuously proposing new normative theories of justice – focus on analyzing the reasons, significance, and consequences of such kinds of disagreements. The next two sections are analytical. The first sketches five (...) possible reasons for deep disagreements among notions of social and political justice. The second discusses the meta-ethical relevance of the lack of consensus on justice and rejects ethical realism and cognitivism based on the argument from deep disagreements. (shrink)

This paper provides a reinterpretation of some of the most influential skeptical arguments, Agrippa’s trilemma, meta-regress arguments, and Cartesian external world skepticism. These skeptical arguments are reasonably regarded as unsound arguments about the extent of our knowledge. However, reinterpretations of these arguments tell us something significant about the preconditions and limits of persuasive argumentation. These results contribute to the ongoing debates about the nature and resolvability of deep disagreement. The variety of skeptical arguments shows that we must distinguish (...) different types of deep disagreement. Moreover, the reinterpretation of skeptical arguments elucidates that deep disagreement cannot be resolved via argumentation. (shrink)

Scholars have long recognized the existence of myriad widespread deep disagreements on values, justice, morality, and ethics. In order to come to terms with such deep disagreements, resistant to rational solution, this article asserts the need for developing an ethics of disagreement. The reality that theoretical disagreements often turn into practical conflicts is a major justification for why such an ethics is necessary. This paper outlines an ethics of deep disagreement that is primarily conceived of (...) as a form of virtue ethics. Such an ethics asks opposing parties in moral and intellectual conflicts to acknowledge that (a) deep disagreements exist, (b) opposing positions should be recognized as worthy of respect, and that (c) one should seek dialogue and mutual understanding. This ethical approach conceives of toleration as a moral and political virtue and presents an argument for toleration based on deep disagreements. (shrink)

I intend to bring recent work applying virtue theory to the study of argument to bear on a much older problem, that of disagreements that resist rational resolution, sometimes termed "deep disagreements". Just as some virtue epistemologists have lately shifted focus onto epistemic vices, I shall argue that a renewed focus on the vices of argument can help to illuminate deep disagreements. In particular, I address the role of arrogance, both as a factor in the diagnosis of (...) class='Hi'>deep disagreements and as an obstacle to their mutually acceptable resolution. Arrogant arguers are likely to make any disagreements to which they are party seem deeper than they really are and arrogance impedes the strategies that we might adopt to resolve deep disagreements. As a case in point, since arrogant or otherwise vicious arguers cannot be trusted not to exploit such strategies for untoward ends, any policy for deep disagreement amelioration must require particularly close attention to the vices of argument, lest they be exploited by the unscrupulous. (shrink)

In this paper, I present two tools that help shed light on deep disagreements and their epistemological consequences. First, I argue that we are best off construing deep disagreements as disagreements over conflicting understandings of certain concepts. More specifically, I suggest that deep disagreements are disagreements over how to understand concepts that play what Michael Friedman calls a “constitutive” role for speakers. Second, I argue that we need a better understanding of what speakers are doing when they (...) engage in deep disagreements—what speech acts they are carrying out. I show that we are best off not reducing the relevant speech acts to more familiar speech act kinds, such as assertions or imperatives. I argue that when a speaker articulates an understanding of a concept, they are in part carrying out an act of stipulation. I provide an account of the pragmatics of stipulation and apply the account to examples of deep disagreement. Focusing on the stipulative dimension of deep disagreement opens up, in turn, a novel approach to defusing the epistemological challenges such disagreement seems to pose. (shrink)

In this paper I begin by examining Fogelin’s account of deep disagreement. My contention is that this account is so deeply flawed as to cast doubt on the possibility that such deep disagreements actually happen. Nevertheless, I contend that the notion of deep disagreement itself is a useful theoretical foil for thinking about argumentation. The second part of this paper makes this case by showing how thinking about deep disagreements from the perspective of rhetoric, (...) Walton-style argumentation theory, computation, and normative pragmatics can all yield insights that are useful no matter what one’s orientation within the study of argument. Thus, I conclude that deep disagreement –even if it were to turn out that there are no real-world occurrences of it to which we can point–is useful for theorists of argumentation. In this wise, deep disagreement poses a theoretical challenge for argumentation theory not unlike that posed by radical skepticism for traditional epistemology. (shrink)

In this paper, I will argue for a complex of three theses. First, that the problem of deep disagreement is an instance of the regress problem of justification. Second, that the problem of deep disagreement, as a regress problem, depends on a dialecticality requirement for arguments. Third, that the dialecticality requirement is plausible and defensible.

Questions surrounding deep disagreement have gained significant attention in recent years. One of the central debates is metaphysical, focusing on the features that make a disagreement deep. Proposals for what makes disagreements deep include theories about hinge propositions and first epistemic principles. In this paper, I criticize this metaphysical discussion by arguing that it is methodologically flawed. Deep disagreement is a technical or semi-technical term, but the metaphysical discussion mistakenly treats it as a (...) common-sense concept to be analyzed and captured by our pre-theoretical intuitions. Since the literature on deep disagreement is subject to this fundamental confusion and deep disagreement is not a helpful umbrella term either, I propose eliminating the notion of deep disagreement from the philosophical discourse. Instead of analyzing the nature of deep disagreement, we should develop theories about different forms of disagreement, including disagreement about hinge propositions and disagreement about epistemic principles, and, in particular, a theory of rationally irresolvable disagreement.

The existence of deep moral disagreement is used in support of views ranging from moral relativism to the impossibility of moral expertise. This is done despite the fact that it is not at all clear whether deep moral disagreements actually occur, as the usually given examples are never of real life situations, but of some generalized debates on controversial issues. The paper will try to remedy this, as any strength of arguments appealing to deep moral (...) class='Hi'>disagreement is partly depended on the fact the disagreement exists. This will be done by showing that some real life conflicts that are intractable, i.e. notoriously difficult to resolve, share some important features with deep moral disagreement. The article also deals with the objection that the mere conceptual possibility renders illustrations of actually happening deep moral disagreements unnecessary. The problem with such objection is that it depends on theoretical assumptions (i.e. denial of moral realism) that are not uncontroversial. Instead, the article claims we need not only suppose deep moral disagreements exist because they actually occur when some intractable conflicts occur. Thus, in so far as to the deep moral disagreement’s existence, the arguments appealing to it are safe. But as intractable conflicts can be resolved, by seeing deep moral disagreements as constitutive part of them, we might have to consider whether deep moral disagreements are resolvable too. A brief suggestion of how that might look like is given in the end of the paper. (shrink)

To say that a philosophical dispute is ‘merely verbal’ seems to be an important diagnosis. If that diagnosis is correct for a particular dispute, then the right thing to do would be to declare that dispute to be over. The topic of what the disputing parties were fighting over was just a pseudo-problem (thus not really a problem), or at least – if there is a sense in which also merely verbal disputes indicate some problem, for example, insufficient clarity of (...) terminology – this problem is not substantial, or not as substantial as the disputing parties believed their problem initially to be. In this paper I will try to clarify what it means if we diagnose that two arguing parties are having a merely verbal dispute. (shrink)

The discussion about deep disagreement has gained significant momentum in the last several years. This discussion often relies on the intuition that deep disagreement is, in some sense, rationally irresolvable. In this paper, I will provide a theory of rationally irresolvable disagreement. Such a theory is interesting in its own right, since it conflicts with the view that rational attitudes and procedures are paradigmatic tools for resolving disagreement. Moreover, I will suggest replacing discussions about (...) deep disagreement with an analysis of rationally irresolvable disagreement, since this notion can be more clearly defined than deep disagreement and captures the basic intuitions underlying deep disagreement. I will first motivate this project by critically assessing the current debate about deep disagreement. I then detail the notions of rationality and resolvable disagreement which are crucial for a suitable theory of rationally irresolvable disagreement before sketching various instances of rationally irresolvable disagreement. Finally, I argue for replacing theories of deep disagreement with theories of rationally irresolvable disagreement, an approach that has significant advantages over existing theories of deep disagreement which focus on hinge propositions or fundamental epistemic principles.

Conciliatory theories of disagreement face a revenge problem; they cannot be coherently believed by one who thinks they have peers who are not conciliationists. I argue that this is a deep problem for conciliationism.

The existence of deep and persistent moral disagreement poses a problem for a defender of moral knowledge. It seems particularly clear that a philosopher who thinks that we know a great many moral truths should explain how human populations have failed to converge on those truths. In this paper, I do two things. First, I show that the problem is more difficult than it is often taken to be, and second, I criticize a popular response, which involves claiming (...) that many false moral beliefs are the product of nonmoral ignorance.

While the epistemic significance of disagreement has been a popular topic in epistemology for at least a decade, little attention has been paid to logical disagreement. This monograph is meant as a remedy. The text starts with an extensive literature review of the epistemology of (peer) disagreement and sets the stage for an epistemological study of logical disagreement. The guiding thread for the rest of the work is then three distinct readings of the ambiguous term ‘logical (...) disagreement’. Chapters 1 and 2 focus on the Ad Hoc Reading according to which logical disagreements occur when two subjects take incompatible doxastic attitudes toward a specific proposition in or about logic. Chapter 2 presents a new counterexample to the widely discussed Uniqueness Thesis. Chapters 3 and 4 focus on the Theory Choice Reading of ‘logical disagreement’. According to this interpretation, logical disagreements occur at the level of entire logical theories rather than individual entailment-claims. Chapter 4 concerns a key question from the philosophy of logic, viz., how we have epistemic justification for claims about logical consequence. In Chapters 5 and 6 we turn to the Akrasia Reading. On this reading, logical disagreements occur when there is a mismatch between the deductive strength of one’s background logic and the logical theory one prefers (officially). Chapter 6 introduces logical akrasia by analogy to epistemic akrasia and presents a novel dilemma. Chapter 7 revisits the epistemology of peer disagreement and argues that the epistemic significance of central principles from the literature are at best deflated in the context of logical disagreement. The chapter also develops a simple formal model of deep disagreement in Default Logic, relating this to our general discussion of logical disagreement. The monograph ends in an epilogue with some reflections on the potential epistemic significance of convergence in logical theorizing. (shrink)

This thesis engages with three topics and the relationships between them: (i) the phenomenon of disagreement (paradigmatically, where one person makes a claim and another denies it); (ii) the normative character of disagreements (the issue of whether, and in what sense, one of the parties is “at fault” for believing something that’s untrue); (iii) the issue of which theory of what truth is can best accommodate the norms relating belief and truth. People disagree about all sorts of things: about (...) whether climate is changing, death penalty is wrong, sushi is delicious, or Louis C.K. is funny. However, even focusing on disagreements in the evaluative domain (e.g., taste, moral and comedic), where people have the intuition that there is ‘no fact of the matter’ about who is right, there are significant differences that require explanation. For instance, disagreement about taste is generally perceived as shallow. People accept to disagree and live comfortably with that fact. By contrast, moral disagreement is perceived as deep and sometimes hard to tolerate. Comedic disagreement is similar to taste. However, it may involve an element of ‘intellectual snobbery’ that is absent in taste disagreement. The immediate questions are whether these contrasts allow of precise characterization and what is responsible for them. I argue that, once a case is made for the truth-aptness of judgments in these areas, the contrast can be explained in terms of variable normative function of truth – as exerting a lightweight normative constraint in the domain of taste and a stricter constraint in the moral domain. In particular I claim that while truth in the moral domain exerts a sui generis deontic control, this normative feature of truth is silent in both the taste and the comedic domains. This leads me to investigate how to conceive of truth in the light of normative variability. I argue that an amended version of deflationism – minimally inflated deflationism – can account for the normative variability of truth. (shrink)

This chapter has two sections, each focusing on a distinct way in which ethical disagreement and variations in ethical judgment matter for theories of ethical thought and talk. In the first section, we look at how the variation poses problems for both cognitivist and non-cognitivist ways of specifying the nature of ethical judgments. In the second, we look at how disagreement phenomena have been taken to undermine cognitivist accounts, but also at how the seeming variation in cognitive and (...) non-cognitive contents between parties of deep ethical disagreement challenges both cognitivist and non-cognitivist accounts of disagreement itself.

Gauss’s quadratic reciprocity theorem is among the most important results in the history of number theory. It’s also among the most mysterious: since its discovery in the late 18th century, mathematicians have regarded reciprocity as a deeply surprising fact in need of explanation. Intriguingly, though, there’s little agreement on how the theorem is best explained. Two quite different kinds of proof are most often praised as explanatory: an elementary argument that gives the theorem an intuitive geometric interpretation, due to Gauss (...) and Eisenstein, and a sophisticated proof using algebraic number theory, due to Hilbert. Philosophers have yet to look carefully at such explanatory disagreements in mathematics. I do so here. According to the view I defend, there are two important explanatory virtues—depth and transparency—which different proofs (and other potential explanations) possess to different degrees. Although not mutually exclusive in principle, the packages of features associated with the two stand in some tension with one another, so that very deep explanations are rarely transparent, and vice versa. After developing the theory of depth and transparency and applying it to the case of quadratic reciprocity, I draw some morals about the nature of mathematical explanation. (shrink)

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

In this book symposium text, I focus on Ciurria’s critique of P. F. Strawson’s incredibly influential paper “Freedom and Resentment”, and more generally present-day Strawsonians about moral responsibility. Ciurria rightfully argues that the picture painted of “our responsibility practices” is highly idealized; it ignores crucial power asymmetries and oppression. I agree with this. However, it seems to me that Ciurria sometimes lacks awareness of exactly how profound the disagreement between her and Strawson and his followers is.

In this article I discuss David Shoemaker’s recently published piece “Responsibility: The State of the Question. Fault Lines in the Foundations.” While agreeing with Shoemaker on many points, I argue for a more unified diagnosis of the seemingly intractable debates that plague (what I call) “responsibility studies.” I claim that, of the five fault lines Shoemaker identifies, the most basic one is about the role that the notion of deserved harm should play in the theory of moral responsibility. I argue (...) that the deep divide between those theorists who affirm and those who deny that moral responsibility is essentially about the justification of desert thus understood can be traced to the disagreement about whether the focus on the reactive attitudes by itself entails that moral responsibility has nothing to do with traditional questions about desert and free will. I then show that the seeming intractableness of the other four fault lines Shoemaker identifies is expectable and explicable in light of this more basic disagreement. After this diagnostic work, I conclude by suggesting a solution to the “morass” that has taken over responsibility studies: theorists working in the field should acknowledge that it has effectively bifurcated into two discrete subareas, which I suggest calling “retribution studies” and “interpersonal studies.” -/- .

The goal of this dissertation is to specify the feasibility conditions of compromise. More specifically, the goal of this dissertation is to specify the conditions of increasing the feasibility of compromise. The underlying assumption here is that feasibility is a scalar concept, meaning that a socio-political ideal can be feasible to different degrees (Lawford-Smith 2013). In order to specify the conditions of increasing the feasibility of compromise, it is necessary to first identify potential feasibility constraints. The main chapters of this (...) dissertation are devoted to this task. -/- My research identifies two kinds of feasibility constraints that compromise potentially faces: A psychological feasibility constraint on realizing moral compromise (i.e. compromise on moral issues) and a structural feasibility constraint on realizing fair compromise. The psychological feasibility constraint consists in what I call an “affective aversion” to compromise. Affective aversion designates a deep emotional reluctance to compromise on moral values, which, I propose, can be reduced by cultivating an affective attitude of respect for other persons. The structural feasibility constraint refers to the process through which a compromise is achieved. I argue that if a fair compromise is the goal, the process of compromising needs to be based on deliberation rather than on the negotiation or bargaining processes that are commonly associated with compromise. Based on these results, my research indicates a) that an affective cultivation of respect is a condition for increasing the feasibility of moral compromise; and b) that deliberation, not negotiation or bargaining, is a condition for increasing the feasibility of fair compromise.

Accounts of deep disagreements can generally be categorized as optimistic or pessimistic. Pessimistic interpretations insist that the depth of deep disagreements precludes the possibility of rational resolution altogether, while optimistic variations maintain the contrary. Despite both approaches’ respective positions, they nevertheless often, either explicitly or implicitly, agree on the underlying assumption that argumentation offers the only possible rational resolution to deep disagreements. This paper challenges that idea by, first, diagnosing this argument-only model of arriving at rational resolutions, (...) second, articulating a competing but undertheorized Hegelian-informed approach, and third, attending briefly to some of the challenges of such an approach.

Is it possible to disagree with someone without considering them cognitively flawed? The answer seems to be a resounding yes: disagreeing with someone doesn't entail thinking less of them. You can disagree with someone and not think that they are unreasonable. Deep disagreements, however, may challenge this assumption. A disagreement is deep when it involves many interrelated issues, including the proper way to resolve the disagreement, resulting in its persistence. The parties to a deep (...) class='Hi'>disagreement can hold neutral or even positive judgements of each other's epistemic character, as parties’ judging each other's epistemic character negatively (i.e., epistemic disdain) is not a defining feature of deep disagreements. When analysing real-life cases, however, we find that epistemic disdain is typical of deep disagreements. In this article, I analyse why this is the case. Given that epistemic disdain undermines cognitive peerhood, the prospects of deep disagreements between epistemic peers seem bleak. Finally, it is discussed how the phenomenon of epistemic disdain, as it relates to deep disagreements, may increase affective polarisation. (shrink)

Reason is the tool of our knowledge but in philosophy this tool encounters difficulties, especially, when it is faced with the big questions - the source of philosophy's deep disagreements. Another difficulty arises from the fact that philosophy and religion cross each other's path: the first draws deductions from rational principles in its approach to religion while the second does not remain firm on its terrain - it keeps looking for rational answers. In essence, this is what this article (...) deals with. If for thousands of years philosophers have been taking turns in arguing and disagreeing with one another on some big questions, there comes a time when the circle has to be broken. In fact, that time has come; this article offers a novel approach to end the age-old debate on, for instance, God talk. (shrink)

The design process in Kashmiri carpet weaving is distributed over a number of actors and artifacts and is mediated by a weaving notation called talim. The script encodes entire design in practice-specific symbols. This encoded script is decoded and interpreted via design-specific conventions by weavers to weave the design embedded in it. The cognitive properties of this notational system are described in the paper employing cognitive dimensions (CDs) framework of Green (People and computers, Cambridge University Press, Cambridge, 1989) and Blackwell (...) et al. (Cognitive technology: instruments of mind—CT 2001, LNAI 2117, Springer, Berlin, 2001). After introduction to the practice, the design process is described in ‘The design process’ section which includes coding and decoding of talim. In ‘Cognitive dimensions of talim’ section, after briefly discussing CDs framework, the specific cognitive dimensions possessed by talim are described in detail. (shrink)

Some moral disagreements are so persistent that we suspect they are deep : we would disagree even when we have all relevant information and no one makes any mistakes. The possibility of deep disagreement is thought to drive cognitivists toward relativism, but most cognitivists reject relativism. There is an alternative. According to divergentism, cognitivists can reject relativism while allowing for deep disagreement. This view has rarely been defended at length, but many philosophers have implicitly endorsed (...) its elements. I will defend it. (shrink)

Existing studies of the multi-group dynamics of prejudiced societies focus on the social- psychological knowledge behind the relevant processes. We instead create a multi-agent framework that simulates the propagation of prejudice and measures its tangible impact on prosperity. Levels of prosperity are tracked for individuals as well as larger social structures including groups and factions. We model social interactions using the Continuous Prisoner's Dilemma (CPD) and a new agent type called a prejudiced agent. Our simulations show that even modeling prejudice (...) as an exclusively out-group phenomenon nonetheless generates implicit in-group promotion, leading to higher relative prosperity of a prejudiced population. This skew in prosperity is seen to be correlated to factors such as size difference between groups, and the fraction of prejudiced agents in a group. Our model is a step towards a deeper understanding of the origins, propagation, and ramifications of prejudice through simulative studies grounded in apt theoretical backgrounds. (shrink)

If this can be seen as a long way from the beginning of the ancient history, where humans have envisioned different new things and then invented them to make their life’s working smoother and easier, then it can be found that they have attributed their discoveries to various aspects and names of Gods and tried to signify their belief in the form of portraying the God’s powers through the nature of their discovery. Rather, in much modern times, when humans have (...) developed the natural insights and prorated those in the form of a much more logically biased discovery, then, the atheists have started to dominate the scientific arena for their foreplay in the work of their discoveries. However, as time passes by, five special types of research communities have gathered to allocate their discovered data’s in the respective norms as such, i) Atheists to whom, there is in essence no God and nothing in this universe can be attributed to them. ii) Believer of only one God as a whole, where the principle of religious biasing is effluent and supreme in their regards of the physical laws associated with the life and stimuli, iii) Believer of multiple God’s as a whole which poses no such scientific evaluation but can be thought of as a conjugate mechanism for the creator of the universe, iv) A divine supreme, where there is exactly no God, but the whole universe is a manifestation of the nature, where nature indirectly focuses the presence of God’s or the supreme creator that maintains symmetry and working of the universe, v) The not-so-sure about mechanism of the God’s presence, where the researcher sometimes tends to belief in God when something magical happens and attribute all to their divine grace, or in times of failures where they accused them for not being philosophically intrinsic as to their own needs, and in times with the believe that, ‘we won’t believe what we can’t see!’, either in the middle of the good or bad moments or in general in a casual and carefree mode. But, this should be kept in mind, that, the Eastern mysticism has always signifies God’s action in terms of every scientific actions with a proper mythological essence which when accompanied by knowledge produces something so scientific in the ancient of the days, that modern day researchers also have had no options left than to attribute affirmation to the fantastic achievements in the ‘so’ ancient times discovery with a strict modern effluence. Therefore, to model this paper, I have gathered data’s and ideas from researchers of various fields mostly (PhDs) in their respective discipline, so as to emulate their minds in the norms of God and its associated beliefs.

This article describes various ways actors in Kashmiri carpet weaving practice deploy a range of artifacts, from symbolic, to material, to hybrid, in order to achieve diverse cognitive accomplishments in their particular task domains: information representation, inter and intra-domain communication, distribution of cognitive labor across people and time, coordination of team activities, and carrying of cultural heritage. In this repertoire, some artifacts position themselves as naïve tools in the actors’ environment to the point of being ignored; however, their usage-in-context unfolds (...) their cognitive involvement in the tasks. These usages-in-context are shown through artifact analysis of their routine, improvised, and opportunistic uses, where cognitive artifacts like talim—the central artifact of this practice—are shown to play not only multifunctional roles beyond representation, but are also complemented by trade-specific skills bearing strong cognitive implications in a task.

The design process in Kashmiri carpet weaving is a distributed process encompassing a number of actors and artifacts. These include a designer called naqash who creates the design on graphs, and a coder called talim-guru who encodes that design in a specific notation called talim which is deciphered and interpreted by the weavers to weave the design. The technological interventions over the years have influenced these artifacts considerably and triggered major changes in the practice, from heralding profound cognitive accomplishments in (...) manually driven design process causing major alterations in the overall structure of the practice. The recent intervention is by the digital technology: on the one hand, it has brought precision and speedy processing in the design process, and on the other, it has eliminated some of the crucial actors from the practice. This paper, which forms part of a larger study on the situated and distributed cognitive process in Kashmiri carpet-weaving practice, describes the technological makeover of the design artifacts involved in this practice over the years and their resultant cognitive impact on the design process as well as on the practice.

Deliberative politics should start from an adequate and differentiated image of our dialogical practices and their normative structures; the ideals that we eventually propose for deliberative politics should be tested against this background. In this article I will argue that equal respect, understood as respect a priori conferred on persons, is not and should not be counted as a constitutive normative ground of public discourse. Furthermore, requiring such respect, even if it might facilitate dialogue, could have negative effects and lead (...) to fallacious paths of thought –as seems to happen on matters of deep disagreement such as the Colorado Fundamentalist/Gay HIV issue I discuss in paragraph 6. I will put forward this argument from the standpoint of argumentation or discourse theory, drawing consequences for dialogical theories of politics. Basing my argument on a pluralistic notion of public discourse – understood as a mixed discourse of persuasion, information-seeking and negotiation – I will argue that respect is a dynamic, situational phenomenon, and that the norm of equal respect for persons is contextually contingent in political deliberation: equal respect should be considered as a potential outcome, a discursive achievement – which I understand as a second order consensus achieved dynamically on a provisional basis – rather than as an universal condition for dialogue.

As a topic in the philosophy of psychology, dreaming is a fascinating, diverse, and severely underdeveloped area of study. The topic excites intense public interest in its own right, while also challenging our confidence that we know what the words “conscious” and “consciousness” mean. So dreaming should be at the forefront of our interdisciplinary investigations: theories of mind which fail to address the topic are incomplete. This chapter illustrates the tight links between conceptual and empirical issues by highlighting surprisingly (...) class='Hi'>deep disagreements among leading dream scientists over what might seem basic aspects of their topic.

Given the deep disagreement surrounding population axiology, one should remain uncertain about which theory is best. However, this uncertainty need not leave one neutral about which acts are better or worse. We show that as the number of lives at stake grows, the Expected Moral Value approach to axiological uncertainty systematically pushes one towards choosing the option preferred by the Total and Critical Level views, even if one’s credence in those theories is low.

Epistemic entitlement is a species of internalist warrant that can be had without any evidential support. Unfortunately, for this kind of warrant the so-called problem of demarcation arises, a form of epistemic relativism. I first present entitlement theory and examine what the problem of demarcation is exactly, rejecting that it is either based on bizarreness or disagreement in favour of the thesis that the problem of demarcation is based on epistemic arbitrariness. Second, I argue that arbitrariness generates a problem (...) for entitlement because it undermines epistemic warrant. Third, I draw out some of the consequences that arbitrariness has for an entitlement epistemology, notably that it threatens to generalise to all our beliefs. Finally, I examine how different solutions to the problem of demarcation fare with respect to the danger of arbitrariness. I argue that none of the considered options succeeds in dealing with the risks of arbitrariness. (shrink)

Kaplan (1989) famously claimed that monsters--operators that shift the context--do not exist in English and "could not be added to it". Several recent theorists have pointed out a range of data that seem to refute Kaplan's claim, but others (most explicitly Stalnaker 2014) have offered a principled argument that monsters are impossible. This paper interprets and resolves the dispute. Contra appearances, this is no dry, technical matter: it cuts to the heart of a deep disagreement about the fundamental (...) structure of a semantic theory. We argue that: (i) the interesting notion of a monster is not an operator that shifts some formal parameter, but rather an operator that shifts parameters that play a certain theoretical role; (ii) one cannot determine whether a given semantic theory allows monsters simply by looking at the formal semantics; (iii) theories which forbid shifting the formal "context" parameter are perfectly compatible with the existence of monsters (in the interesting sense). We explain and defend these claims by contrasting two kinds of semantic theory--Kaplan's (1989) and Lewis's (1980). (shrink)

This paper compares current ways of modeling the inferential structure of practical reasoning arguments, and proposes a new approach in which it is regarded in a modular way. Practical reasoning is not simply seen as reasoning from a goal and a means to an action using the basic argumentation scheme. Instead, it is conceived as a complex structure of classificatory, evaluative, and practical inferences, which is formalized as a cluster of three types of distinct and interlocked argumentation schemes. Using two (...) real examples, we show how applying the three types of schemes to a cluster of practical argumentation allows an argument analyst to reconstruct the tacit premises presupposed and evaluate the argumentative reasoning steps involved. This approach will be shown to overcome the limitations of the existing models of practical reasoning arguments within the BDI and commitment theoretical frameworks, providing a useful tool for discourse analysis and other disciplines. In particular, applying this method brings to light the crucial role of classification in practical argumentation, showing how the ordering of values and preferences is only one of the possible areas of deep disagreement.

The work of Thomas White represents a systematic attempt to combine the best of the new science of the seventeenth century with the best of Aristotelian tradition. This attempt earned him the criticism of Hobbes and the praise of Leibniz, but today, most of his attempts to navigate between traditions remain to be explored in detail. This paper does so for his ontology of accidents. It argues that his criticism of accidents in the category of location as entities over and (...) above substances was likely aimed at Francisco Suárez, and shows how White’s worries about the analysis of location were linked with his broader cosmological views. White rejects real qualities, but holds that the quantity of a substance is somehow distinct from its bearer. This reveals a common ground with some of his scholastic interlocutors, but lays bare a deep disagreement with thinkers like Descartes on the nature of matter. (shrink)

According to contractualist theories in ethics, whether an action is wrong is determined by whether it could be justified to others on grounds no one could reasonably reject. Contractualists then think that reasonable rejectability of principles depends on the strength of the personal objections individuals can make to them. There is, however, a deep disagreement between contractualists concerning from which temporal perspective the relevant objections to different principles are to be made. Are they to be made on the (...) basis of the prospects the principles give to different individuals ex ante or on the basis of the outcomes of the principles ex post? Both answers have been found to be problematic. The ex ante views make irrelevant information about personal identity morally significant and lead to objectionable ex ante rules, whereas ex post views lead to counterintuitive results in the so-called different harm and social risk imposition cases. The aim of this article is to provide a new synthesis of these views that can avoid the problems of the previous alternatives. I call the proposal ‘risk-acknowledging’ ex post contractualism. The crux of the view is to take into account in the comparisons of different objections both the realized harms and the risks under which individuals have to live. (shrink)

This essay reassesses the relation between Kant and Kripke on the relation between necessity and the a priori. Kripke famously argues against what he takes to be the traditional view that a statement is necessary only if it is a priori, where, very roughly, what it means for a statement to be necessary is that it is true and could not have been false and what it means for a statement to be a priori is that it is knowable independently (...) of experience. Call such a view the Entailment Thesis. Along with many Kant scholars, Kripke thinks that Kant endorses the Entailment Thesis. Thus Kripke and many others take his arguments against the Entailment Thesis to tell against Kant and to mark an important point of disagreement with him. I will argue that this is a mistake. Kant does not endorse the Entailment Thesis that Kripke and many others attribute to him. He does endorse two quite different theses concerning the relation between necessity and the a priori, as he conceives them. One is a matter of definition and the other is a very substantial philosophical thesis indeed—to establish it is the aim of the entire Critique of Pure Reason. But Kripke’s arguments against the Entailment Thesis tell against neither of Kant’s theses, as they involve crucially different conceptions of necessity and the a priori. This superficial lack of disagreement masks deep disagreements, but these result from divergent views regarding matters such as realism, modal epistemology, and philosophical methodology; views which Kant does a lot, and Kripke very little, to argue for.

The language of rights pervades modern social and political discourse and yet there is deep disagreement amongst citizens, politicians and philosophers about just what they mean. Who has them? Who should have them? Who can claim them? What are the grounds upon which they can be claimed? How are they related to other important moral and political values such as community, virtue, autonomy, democracy and social justice? In this book, Duncan Ivison offers a unique and accessible integration of, (...) and introduction to, the history and philosophy of rights. He focuses especially on the politics of rights: the fact that rights have always been, and will remain, deeply contested. He discusses not only the historical contexts in which some of the leading philosophers of rights formed their arguments, but also the moral and logical issues they raise for thinking about the nature of rights more generally. At each step, Ivison also considers various deep criticisms of rights, including those made by communitarian, feminist, Marxist and postmodern critics. The book is aimed at students and readers coming to these issues for the first time, but also at more knowledgeable readers looking for a distinctive integration of history and theory as applied to questions about the nature of rights today.

The work of Thomas Kuhn has been very influential in Anglo-American philosophy of science and it is claimed that it has initiated the historical turn. Although this might be the case for English speaking countries, in France an historical approach has always been the rule. This article aims to investigate the similarities and differences between Kuhn and French philosophy of science or ‘French epistemology’. The first part will argue that he is influenced by French epistemologists, but by lesser known authors (...) than often thought. The second part focuses on the reactions of French epistemologists on Kuhn’s work, which were often very critical. It is argued that behind some superficial similarities there are deep disagreements between Kuhn and French epistemology. This is finally shown by a brief comparison with the reaction of more recent French philosophers of science, who distance themselves from French epistemology and are more positive about Kuhn. Based on these diverse appreciations of Kuhn, a typology of the different positions within the philosophy of science is suggested. (shrink)

What kind of thing, as it were, is power and how does it fit into our understanding of the social world? I approach this question by exploring the pragmatic character of power ascriptions, arguing that they involve fictional expectations directed at an open future. When we take an agent to be powerful, we act as if that agent had a robust capacity to make a difference to the actions of others. While this pretense can never fully live up to a (...) social reality whose future is open, acting on such expectations helps constitute social order. Fictional expectations are thus built into the material practices that constitute power. This account, I argue, helps us make sense of some of the deep disagreements about the nature of power. I develop the account by drawing on Thomas Hobbes’s myth of an original institution of sovereign power before expanding it to other forms of power. (shrink)

To have a well-functioning principle of academic freedom, we need to distin-guish critique from an infringement of academic freedom. To achieve this goal, this paper presents three necessary conditions for something to be an infringe-ment of academic freedom. These conditions allow to delineate cases in which at least one of the three conditions is not fulfilled. These are contrast cases that might – at first glance – look like infringements of academic freedom but are, in fact, not so. I will (...) refer to five such kinds of contrast cases: (1) discrimination and thus a more general kind of unjust treatment of a person engaged in aca-demic affairs, (2) infringement of freedom of speech or other non-academic intel-lectual freedoms, (3) mere critique, (4) justified critique that leads to justified limitations of someone’s academic freedom, and (5) cases of deep disagreement. Special attention will be given to vulnerabilities concerning unjustified silencing of critique, which haunt fields that lack clear and agreed-on ethical or academic standards. (shrink)

This is a defense of Pyrrhonian skepticism against the charge that the suspension of judgment based on equipollence is vitiated by the assent given to the equipollence in question. The apparent conflict has a conceptual side as well as a practical side, examined here as separate challenges with a section devoted to each. The conceptual challenge is that the skeptical transition from an equipollence of arguments to a suspension of judgment is undermined either by a logical contradiction or by an (...) epistemic inconsistency, perhaps by both, because the determination and affirmation of equipollence is itself a judgment of sorts, one that is not suspended. The practical challenge is that, independently of any conceptual confusion or contradiction, suspending judgment in reaction to equipollence evinces doxastic commitment to equipollence, if only because human beings are not capable of making assessments requiring rational determination without believing the corresponding premises and conclusions to be true. The two analytic sections addressing these challenges are preceded by two prefatory sections, one laying out the epistemic process, the other reviewing the evidentiary context. The response from the conceptual perspective is that the suspension of judgment based on equipollence is not a reasoned conclusion adopted as the truth of the matter but a natural reaction to an impression left by the apparently equal weight of opposing arguments. The response from the practical perspective is that the acknowledgment of equipollence is not just an affirmation of the equal weight of arguments but also an admission of inability to decide, suggesting that any assent, express or implied, is thrust upon the Pyrrhonist in a state of epistemic paralysis affecting the will and the intellect on the matter being investigated. This just leaves a deep disagreement, if any, regarding whether equipollence is an inference based on discursive activity or an impression coming from passive receptivity. But this, even if resolved in favor of the critic (which it need not and ought not be), is not the same as confusion or inconsistency on the part of the Pyrrhonist, the demonstration of which is the primary aim of this paper.
