Argumentation is pervasive in everyday life. Understanding what makes a strong argument is therefore of both theoretical and practical interest. One factor that seems intuitively important to the strength of an argument is the reliability of the source providing it. Whilst traditional approaches to argument evaluation are silent on this issue, the Bayesian approach to argumentation (Hahn & Oaksford, 2007) is able to capture important aspects of source reliability. In particular, the Bayesian approach predicts that argument content and source (...) reliability should interact to determine argument strength. In this paper, we outline the approach and then demonstrate the importance of source reliability in two empirical studies. These experiments show the multiplicative relationship between the content and the source of the argument predicted by the Bayesian framework. (shrink)

Some mental states are about themselves. Nothing is a cause of itself. So some mental states are not about their causes; they are about things distinct from their causes. If this argument is sound, it spells trouble for causal theories of mental content—the precise sort of trouble depending on the precise sort of causal theory. This paper shows that the argument is sound (§§1-3), and then spells out the trouble (§4).

In this paper I address the question of whether the fact that our colour experiences have a finer‐grained content than our ordinary colour concepts allow us to represent should be taken as a threat to theories of the conceptual content of experience. In particular, I consider and criticise McDowell's response to that argument and propose a possible development of it. As a consequence, I claim that the role of the argument from the finer‐grained content of experience has (...) to be redefined. In particular, I acknowledge that this problem is helpful in order to bring to the fore the issue of the proper characterisation of the constraints upon the possession conditions of perceptual demonstrative concepts. Yet, I contend that, in light of the foregoing discussion, it is neutral with respect to the dispute between conceptual and non‐conceptual theorists. For that dispute hinges on whether it is possible to have experiences with a certain content independently of having the concepts, which are needed for its canonical specification and not on whether those experiences are conceptualisable in all their finesse of grain.

Whereas a number of recent articles have focussed upon whether the thesis of content externalism is compatible with a certain sort of knowledge that is gained via first-person authority,1 far less attention has been given to the relationship that this thesis bears to the possession of knowledge in general and, in particular, its relation to internalist and externalist epistemologies. Nevertheless, although very few actual arguments have been presented to this end, there does seem to be a shared suspicion that (...) content externalism must be incompatible with epistemic internalism. In a recent and influential paper, however, James Chase has challenged this conventional wisdom by offering a subtle defence of the view that content externalism and epistemic internalism are, in fact, compatible after all.2 Our aim here is twofold. First, to show that Chase is only able to achieve this result because he focuses upon the internalist conception of justification, rather than knowledge. Second, to formulate one prima facie argument which shows that an internalist conception of knowledge is incompatible with an externalist conception of content, an argument which, moreover, is not touched by Chase.

The article propose a new way of looking at the relationship between content elaboration and formulation during the production of written argumentative texts. It is hypothesized, that younger students elaborate contents by formulating them, whereas in older students both processes are clearly distinguished. 8 pairs of students aged 10 and 14 and adults with academic background produce a text in a collaborative situation. Three aspects of the production of the first and the last sentence are analyzed in looking (...) at the recorded dialogues: elaboration of argumentative plans; the independant elaboration of contents; the variation of linguistic forms. The results gives the hypothesis credit and show a deep reorganisation of the production process of argumentative texts in ontogenesis. (shrink)

‘Grounding and the indispensability argument’ presents a number of ways in which nominalists can use the notion of grounding to rebut the indispensability argument for the existence of mathematical objects. I will begin by considering the strategy that puts grounding to the service of easy-road nominalists. I will give some support to this strategy by addressing a worry some may have about it. I will then consider a problem for the fast-lane strategy and a problem for easy-road nominalists willing to (...) accept Liggins’ grounding strategy. Both are related to the problem of formulating nominalistic explanations at the right level of generality. I will then consider a problem that Liggins only hints at. This problem has to do with mathematics’ function of providing the sort of covering generalizations we need in scientific explanations. (shrink)

The argument from contradictory contents presented here is based directly on observations about the content of experience. It claims that experience content, if conceptual, allows for contradictions within one and the same content. There are at least two examples of this, the waterfall illusion and the visual experiences of some grapheme-color synesthetes. However, due to a Fregean principle of content individuation, no conceptual contents are contradictory. So experience content is nonconceptual. I motivate a particular version (...) of the argument and defend it against two central objections: First, the objection that there is more than one content involved in apparently self-contradictory experiences and second, the claim that conceptual contents are sometimes contradictory, as is true of some desires. In reaction to the second objection, I argue that we need an explanation of why subjects are not irrational if they do not revise their self-contradictory perceptual experiences, and that the conceptualist has no good account of this. For on his view, just as in thought, conceptual abilities are involved in experience and we are dealing with the same Fregean propositional contents. By contrast, nonconceptualism provides such an explanation, for no conceptual abilities are involved in experience itself, and scenario content is not the kind of content that can be revised under rational pressure.

I deal here with one of Boghossian’s arguments against content externalism, related to ourinferential rationality(to use his term). According to his reasoning, the apriority of our logical abilities is inconsistent with certain externalist assumptions. Nevertheless, the problem constitutes an important challenge foranytheory of content, not just for externalism. Furthermore, when we examine what internalists may propose to solve the problem, we see that externalists have at their disposal a more promising repertoire of possible replies than internalists. In that (...) sense, insofar as Boghossian’s scenario is relevant to the debate externalism/internalism, it can be seen (against Boghossian’s original intention) as providing additional evidence for content externalism.

Abstract I first suggest some ways in which the externalist account of psychological content can be reconciled with the aspectual character of intentionality. I then give an argument against the externalist account which includes as premises the claims that a system capable of having intentional states must understand a language, and that a system that understands a language must be capable of consciousness. I defend the latter claim by arguing that a correct understanding of observation sentences requires conscious, sensory (...) experience, and by appealing to the fact that language has meaning in a holistic manner.

The recent debate over the moral responsibility of psychopaths has centered on whether, or in what sense, they understand moral requirements. In this paper, I argue that even if they do understand what morality requires, the content of their actions is not of the right kind to justify full-blown blame. I advance two independent justifications of this claim. First, I argue that if the psychopath comes to know what morality requires via a route that does not involve a proper (...) appreciation of what it means to cause another harm or distress, the content of violations of rules against harm will be of a lower grade than the content of similar actions by normal individuals. Second, I argue that in order to intend a harm to a person?that is, to intend the distinctive kind of harm that can only befall a person?it is necessary to understand what personhood is and what makes it valuable. The psychopath's deficits with regard to mental time travel ensure that s/he cannot intend this kind of harm. (shrink)

The aim of this paper is to show that the truth of content externalism can be grounded in purely epistemological considerations in which no appeal is made to Twin‐Earth style cases. Content externalism is required to provide an adequate account of perceptual warrant.

This paper provides a novel argument against conceptualism, the claim that the content of human experience, including perceptual experience, is entirely conceptual. Conceptualism entails that the content of experience is limited by the concepts that we possess and deploy. I present an argument to show that such a view is exceedingly costly—if the nature of our experience is entirely conceptual, then we cannot account for concept learning: all perceptual concepts must be innate. The version of nativism that results (...) is incompatible with naturalistic accounts of concept learning. This cost can be avoided, and concept learning accounted for if nonconceptual content of experience is admitted. (shrink)

I offer a meta-level analysis of realist arguments for the reliability of ampliative reasoning about the unobservable. We can distinguish form-driven and content-driven arguments for realism: form-driven arguments appeal to the form of inductive inferences, whilst content-driven arguments appeal to their specific content. After regimenting the realism debate in these terms, I will argue that the content-driven arguments are preferable. Along the way I will discuss how my analysis relates to John Norton’s recent, more general thesis (...) that the grounds for licit induction are always material. (shrink)

General practice consultation has often been characterized by pragma-dialecticians as an argumentative activity type. These characterizations are typically derived from theoretical insights and qualitative analyses. Yet, descriptions that are based on quantitative data are thus far lacking. This paper provides a detailed account of the development of an instrument to guide the quantitative analysis of argumentation in doctor–patient consultation. It describes the implementation and preliminary results of a content analysis of seventy videotaped medical consultations of which the extent (...) and type of doctors’ argumentative support for medical opinions and advice are analyzed. Based on the study results, this paper addresses the merits of observational studies using content analysis as a method for the analysis of argumentative discourse in context as well as some of its key challenges and limitations, laying bare the opportunities for future research.

Discourse connection is a challenging aspect of writing in a second language. This study seeks to investigate the effects of two classroom instructions on discourse connection in writing for EFL college students, focusing on their argumentative writing. Three classes were exposed to different pre-task conditions: receiving reading materials that provide content support for the writing, receiving planning instructions on effective outlining, and receiving no resources. The results showed that the instructions helped students attain better overall coherence in writing. (...) However, noticeable differences between the two experimental groups emerged in terms of cohesion features. The reading group was found to employ more lexical cohesion devices in writing than the outline group, which indicated a heightened genre awareness. This inquiry helped us identify the reading group’s alignment with content support materials, particularly the change in stance as a factor that contributes to a higher level of lexical cohesion in writing.

The idea that there are conceptual schemes, relative to which we conceptualize experience, and empirical content, the “raw” data of experience that get conceptualized through our conceptual schemes into beliefs or sentences, is not new. The idea that there are neither conceptual schemes nor empirical content, however, is. Moreover, it is so new, that only four arguments have so far been given against this dualism, with Donald Davidson himself presenting versions of all four. In this paper, I show (...) that in both the general and Davidson’s specific form the first three arguments against scheme-content dualism rely on the fourth. From many there is just one. Then I show that the fate of the first three arguments against scheme-content dualism hangs on that of the fourth. Finally I present four reasons why the fourth argument fails. For the sake of the dualism’s detractors, therefore, one can only hope that forthcoming arguments against scheme-content dualism fare better than those given so far. (shrink)

In this chapter I argue that there is such a barrier created by self-conscious intentional states—conscious intentional states that are about one’s own conscious intentional states. As we will see, however, this result is entirely compatible with a scientific theory of mind, and, in fact, there is an elegant non-reductive framework in which just such a theory may be pursued.

Disjunctivists (Hinton 1973, Snowdon 1990, Martin 2002, 2006) often motivate their approach to perceptual experience by appealing in part to the claim that in cases of veridical perception, the subject is directly in contact with the perceived object. When I perceive a table, for example, there is no table-like sense-impression that stands as an intermediary between the table and me. Nor am I related to the table as I am to a deer when I see its footprint in the snow. (...) I do not experience the table by experiencing some- thing else over and above the table and its facing surface. I see the facing surface of the table directly. (shrink)

In Wittgenstein on Meaning, Colin McGinn argues that the skeptical argument that Kripke distills from Wittgenstein's rule-following considerations generates at most what might be called meaning skepticism (the non-factuality view of meaning), and not concept skepticism (the non-factuality view of concepts). If correct, this would mean the skeptical reasoning is far less significant than Kripke thinks. Others have seemed to agree with McGinn. I argue that McGinn is wrong here--that, in fact, Kripke's skeptical reasoning has a straightforward extension to concepts. (...) Whether the reasoning succeeds, however, is another matter, which I do not address here. (shrink)

Visual Associative agnosia is a rare perceptual impairment generally resulting from lesions in the infero temporal cortex. Patients suffering from associative agnosia are able to make accurate copies of line drawings, but they are unable to visually recognize objects - including those represented in line drawings - as belonging to familiar high-level kinds. The Rich Content View claims that visual experience can represent high-level kind properties. The phenomenon of associative agnosia appears to present us with a strong case for (...) the Rich Content View. There are reasons for thinking that the experiences of an agnosic patient differ from those of a healthy subject. Given that there is a phenomenal contrast between the experiences of an associative agnosic and those of a healthy perceiver, one may argue that this contrast is due to differences in abilities to represent high-level kinds. I claim that there is indeed a phenomenal contrast between the visual experiences of an agnosic and those of a healthy perceiver. However, the explanation of this contrast that best fits the empirical data is compatible with the view that visual experience does not represent high-level kinds. (shrink)

This paper concerns the question of which properties figure in the contents of perceptual experience. According to conservatives, only low-level properties figure in the contents of perceptual experience. Liberals, on the other hand, claim that high-level properties, such as natural kind properties, artifacts, and even moral properties, can figure in the contents of perceptual experience. I defend a novel argument in favor of liberalism, the Epistemic Argument, which hinges on two crucial claims. The first is that many perceptual experiences of (...) even neurotypical human beings can justify beliefs in high-level properties without providing justification for their low-level constituents. The second claim, roughly, is that any experience that alone provides (defeasible) justification for beliefs about some property p, other things being equal, has p as part of its content. In short, certain perceptual experiences represent high-level but not low-level properties, which entails that liberalism is true. (shrink)

In this study, we propose a way to link the scholarly contents of scientific papers by constructing a knowledge graph based on the semantic organization of argumentation units and relations in scientific papers. We carried out an argumentation graph data model aimed at linking multiple discourses, and also developed a semantic annotation platform for scientific papers and an argumentation graph visualization system. A construction experiment was performed using 12 articles. The final argumentation graph has 1,262 nodes and 1,628 edges, including (...) 1,628 intra-article relations and 190 inter-article relations. Knowledge evolution representation, strategic reading, and automatic abstracting use cases are presented to demonstrate the application of the argumentation graph. In contrast to existing knowledge graphs used in academic fields, the argumentation graph better supports the organization and representation of scientific paper content and can be used as data infrastructure in scientific knowledge retrieval, reorganization, reasoning, and evolution. Moreover, it supports automatic abstract and strategic reading. (shrink)

Several lines of reasoning have been proposed to show the incompatibility of content externalism with justification internalism. In this paper I examine two such lines of reasoning, which both rely on the general idea that since content externalism is incompatible with certain aspects of the alleged privileged character of self-knowledge, it would tend to undermine justification internalism as well. I shall argue that both lines of reasoning, as they stand, lack plausibility, though the core idea of the second (...) line can be reconstructed into a new argument which shows considerable promise. In particular, relying upon the reliability constraint on knowledge, I shall argue that the so-called ‘two-concept’ version of content externalism is incompatible with ‘the transparency of sameness of content’, and thereby would also undermine justification internalism.

When you look at a circular plate at an angle, it looks circular. But there also is a certain sense in which its look can be described as oval. When you move, the plate’s look changes with your perspective on it—nevertheless, it continues to look circular. This chapter investigates whether these “constancy in variation” phenomena can be explained in terms of the representational content of visual experience, and whether constancy in variation provides special, phenomenological, reasons to construe experience as (...) having centered contents. Concentrating on shape, it argues that due to warring phenomenological demands, all views construing constancy in variation as representation of both objective and perspectival properties or features have limited explanatory powers, and that centering does not provide any advantage. By contrast, adopting the non-standard intentionalism called phenomenal intentionalism, we get rather natural explanations of the phenomenology of constancy in variation. (shrink)

A short paper which is pretty much what its title says it is.

For some relativists some of the time the evidence for their view is a puzzling data pattern: On the one hand, there's evidence that the terms in question exhibit some kind of content stability across contexts. On the other hand, there's evidence that their contents vary from one context of use to another. The challenge is to reconcile these two sets of data. Truth relativists claim that their theory can do so better than contextualism and invariantism. Truth relativists, in (...) effect, use an argument to the best explanation: they present data they claim to be able to handle better than any competing theory2. (shrink)

This paper pursues two lines of inquiry. First, drawing on evidence from clinical literature on borderline states of consciousness, I propose a new categorical framework for liminal states of consciousness associated with certain forms of meditative attainment; second, I argue for dissociating phenomenal character from phenomenal content in accounting for the etiology of nonconceptual states of awareness. My central argument is that while the idea of nonconceptual awareness remains problematic for Buddhist philosophy of mind, our linguistic and categorizing practices (...) cannot be adequately explained without considering the ways in which the first-person phenomenology grounds a more basic level of cognitive and affective sensing.

Anonymous argumentation has recently been the focus of public controversy: flash points include the outing of pseudonymous bloggers by newspapers and the launch of an academic journal that expressly permits pseudonymous authorship. However, the controversy is not just a recent one—similar debates took place in the nineteenth century over the then common practice of anonymous journalism. Amongst the arguments advanced by advocates of anonymous argumentation in either era is the contention that it is essential if the widest range of voices (...) are to be heard; amongst the counterarguments of its critics, that it weakens the credibility of individual arguments and irresponsibly cheapens the standard of public discourse. This paper explores some implications of the controversy for the ethics of argumentation in general and virtue theories of argumentation in particular. (shrink)

Although the last decade has seen a proliferation of ontological approaches to arguments, many of them employ ad hoc solutions to representing arguments, lack interoperability with other ontologies, or cover arguments only as part of a broader approach to evidence. To provide a better ontological representation of arguments, we present the Arguments Ontology (ArgO), a small ontology for arguments that is designed to be imported and easily extended by researchers who work in different upper-level ontology frameworks, different logics, and different (...) approaches to argument evaluation. Unlike most ontological approaches to arguments, ArgO utilizes Basic Formal Ontology (BFO) as an upper-level ontology, and may be used alongside other commonly used ontologies in the BFO framework, including boththe Information Artifact Ontology (IAO), and the Information Entity Ontology (INFO). Critically, our proposal is principled, based on rigorous definitions and formal axioms out of which characterizations of arguments naturally fall. It is our hope that ArgO may assist researchers in many projects, including: integrating heterogeneous sources of evidence, structuring the content of semantic wikis, and enhancing semantic reasoning.

In this paper I discuss Heck's new argument for content dualism. This argument is based on the claim that conceptual states, but not perceptual states, meet Evans's Generality Constraint. Heck argues that this claim, together with the idea that the kind of content we should attribute to a mental state depends on which generalizations the state satisfies, implies that conceptual states and perceptual states have different kinds of contents. I argue, however, that it is unlikely that there is (...) a plausible reading of the Generality Constraint under which it is non-trivially true both that conceptual states meet it and that perceptual states do not. Therefore, the soundness of Heck's argument is dubious. En este artículo discuto el nuevo argumento de Heck en favor del dualismo de contenido. Este argumento se basa en la afirmación de que los estados conceptuales, pero no los perceptuales, cumplen con el Requisito de Generalidad de Evans. Heck argumenta que esta afirmación, junto con la idea de que el tipo de contenido que debemos atribuir a un estado mental depende de las generalizaciones que el estado satisface, implica que los estados conceptuales tienen un tipo de contenido diferente del de los estados perceptuales. Yo argumento, sin embargo, que es poco probable que haya una interpretación convincente del Requisito de Generalidad según la cual sea verdadero pero no trivial tanto que los estados conceptuales lo satisfacen como que los perceptuales no. Por lo tanto, la solidez del argumento de Heck es dudosa. (shrink)

Perceptual experiences justify beliefs—that much seems obvious. As Brewer puts it, “sense experiential states provide reasons for empirical beliefs” (this volume, xx). In Mind and World McDowell argues that we can get from this apparent platitude to the controversial claim that perceptual experiences have conceptual content: [W]e can coherently credit experiences with rational relations to judgement and belief, but only if we take it that spontaneity is already implicated in receptivity; that is, only if we take it that experiences (...) have conceptual content. (1994, 162) Brewer agrees. Their view is sometimes called conceptualism; nonconceptualism is the rival position, that experiences have nonconceptual content. One initial obstacle is understanding what the issue is. What is conceptual content, and how is it different from nonconceptual content? Section 1 of this paper explains two versions of each of the rival positions: state (non)conceptualism and content (non)conceptualism; the latter pair is the locus of the relevant dispute. Two prominent arguments for content nonconceptualism—the richness argument and the continuity argument—both fail (section 2). McDowell’s and Brewer’s epistemological defenses of content conceptualism are also faulty (section 3). Section 4 gives a more simple-minded case for conceptualism; finally, some reasons are given for rejecting the claim—on one natural interpretation—that experiences justify beliefs. (shrink)

In this paper we provide a proof theoretical investigation of logical argumentation, where arguments are represented by sequents, conflicts between arguments are represented by sequent elimination rules, and deductions are made by dynamic proof systems extending standard sequent calculi. The idea is to imitate argumentative movements in which certain claims are introduced or withdrawn in the presence of counter-claims. This is done by a dynamic evaluation of sequences of sequents, in which the latter are considered ‘derived’ or ‘not derived’ (...) according to the content of the sequence. We show that decisive conclusions of such a process correspond to well-accepted consequences of the underlying argumentation framework. The outcome is therefore a general and modular proof-theoretical approach for paraconsistent and non-monotonic reasoning with argumentation systems. (shrink)

The paper presents an extended argument for the claim that mental content impacts the computational individuation of a cognitive system (section 2). The argument starts with the observation that a cognitive system may simultaneously implement a variety of different syntactic structures, but that the computational identity of a cognitive system is given by only one of these implemented syntactic structures. It is then asked what are the features that determine which of implemented syntactic structures is the computational structure of (...) the system, and it is contended that these features are certain aspects of mental content. The argument helps (section 3) to reassess the thesis known as computational externalism, namely, the thesis that computational theories of cognition make essential reference to features in the individual's environment. It is suggested that the familiar arguments for computational externalism?which rest on thought experiments and on exegesis of Marr's theories of vision?are unconvincing, but that they can be improved. A reconstruction of the visex/audex thought experiment is offered in section 3.1. An outline of a novel interpretation of Marr's theories of vision is presented in section 3.2. The corrected arguments support the claim that computational theories of cognition are intentional. Computational externalism is still pending, however, upon the thesis that psychological content is extrinsic. (shrink)
