This essay argues that the main lesson of Lewis Carroll's Regress is that arguments are constitutively presuppositional.

Here I will develop a naturalistic account of epistemic reflection and its significance for epistemology. I will first argue that thought, as opposed to mere information processing, requires a capacity for cognitive self-regulation. After discussing the basic capacities necessary for cognitive self-regulation of any kind, I will consider qualitatively different kinds of thought that can emerge when the basic capacities enable the creature to interiorize a form of social cooperation. First, I will discuss second-personal cooperation and the kind of thought (...) that emerges from its interiorization. Then, I will discuss third-personal cooperation and the kind of thought that emerges from its interiorization. We will see that epistemic reflection is the interiorized version of interpersonal argumentation, which is the epistemic component of third-personal cooperation. In developing this account, I will draw heavily on the work of Michael Tomasello and other cognitive scientists advocating the “social intentionality hypothesis”. However, I will show how work done in the defeasible reasoning tradition can provide us with a deeper explanation of some claims made by advocates of the social intentionality hypothesis. Additionally, we will see that work done on social intentionality can help us better understand the significance of knowledge and justification as understood by the defeasible reasoning tradition. We will see that the social intentionality hypothesis and the defeasible reasoning tradition are mutually illuminating. By drawing equally on both, I will provide a novel account of the foundations of knowledge. (shrink)

I will discuss a variety of cases such that the subject's believing truly is somewhat of an accident, but less so than in a Gettier case. In each case, this is because her reasons are not ultimately undefeated full stop, but they are ultimately undefeated with certain qualifications. For example, the subject's reasons might be ultimately defeated considered in themselves but ultimately undefeated considered as a proper part of an inference to the best explanation that is undefeated without qualification. In (...) each section of the paper, I consider different qualifications and show how in each case we get an epistemic standing I call “coach-class knowledge”. First-class knowledge requires justifying reasons that are undefeated without qualification. Coach-class knowledge only requires qualified lack of defeat. I will use this distinction to bring debates over knowledge from falsehood and fake barns to an ecumenical resolution. In both cases, the subject enjoys coach-class rather than first-class knowledge. I will also show that the defeasible reasoning tradition can better account for graded accidental truth than safety theories. (shrink)

Controversy has arisen of late over the claim that deflationism about truth requires that we explain meaning in terms of something other than truth-conditions. This controversy, it is argued, is due to unclarity as to whether the basic deflationary claim that a sentence and a sentence that attributes truth to it are equivalent in meaning is intended to involve the truth- predicate of the object language for which we develop an account of meaning, or is intended to involve the truth- (...) predicate of the metalanguage in which we develop an account of meaning. The former view is compatible with the truth-conditional theory of meaning for the object language, the latter is incompatible with it. However, the former view is also trivially true; hence we should endorse the claim that any form of deflationism worth being interested in is incompatible with understanding meaning truth-conditionally.

In this paper, I examine Wilfrid Sellars’ famous Myth of Jones. I argue the myth provides an ontologically austere account of thoughts and beliefs that makes sense of the full range of our folk psychological abilities. Sellars’ account draws on both Gilbert Ryle and Ludwig Wittgenstein. Ryle provides Sellars with the resources to make thoughts metaphysically respectable and Wittgenstein the resources to make beliefs rationally criticisable. By combining these insights into a single account, Sellars is able to see reasons as (...) causes and, hence, to respect the full range of our folk psychological generalisations. This is achieved by modelling folk psychological practice on theoretical reasoning. But despite frequent misinterpretation, Sellars does not claim that thoughts and beliefs are theoretical concepts. Thus, folk psychological explanation is not theoretical, and hence, it is not replaceable by scientific theory. Hence, scientific concepts will not eliminate folk psychological concepts. Thus, Sellars avoids eliminativism. (shrink)

The standard inferentialist approaches to modal logic tend to suffer from not being able to uniquely characterize the modal operators, require that introduction and elimination rules be interdefined, or rely on the introduction of possible-world like indexes into the object language itself. In this paper I introduce a hypersequent calculus that is flexible enough to capture many of the standard modal logics and does not suffer from the above problems. It is therefore an ideal candidate to underwrite an inferentialist theory (...) of meaning for modal operators. Here I treat specifically the modal logics K, D, T, S4, B, and S5. I show that the calculi are adequate for each set of models, and show that they meet a large set of criteria that are generally thought necessary for a calculus to underwrite a theory of meaning.

I argue that philosophy is like science in three interesting and non-obvious ways. First, the claims made by philosophy are synthetic, not analytic: philosophical claims, just like scientific claims, are not guaranteed by the structure of the concepts they involve. Second, philosophical knowledge is a posteriori, not a priori: the claims established by philosophers depend on the same kind of empirical support as scientific theories. And finally, the central questions of philosophy concern actuality rather than necessity: philosophy is primarily aimed (...) at understanding the actual world studied by science, not some further realm of metaphysical modality.

Enthymemes are traditionally defined as arguments in which some elements are left unstated. It is an empirical fact that enthymemes are both enormously frequent and appropriately understood in everyday argumentation. Why is it so? We outline an answer that dispenses with the so called "principle of charity", which is the standard notion underlying most works on enthymemes. In contrast, we suggest that a different force drives enthymematic argumentation—namely, parsimony, i.e. the tendency to optimize resource consumption, in light of the agent's (...) goals. On this view, the frequent use of enthymemes does not indicate sub-optimal performance of arguers, requiring appeals to charity for their redemption. On the contrary, it is seen as a highly adaptive argumentation strategy, given the need of everyday reasoners to optimize their cognitive resources. Considerations of parsimony also affect enthymeme reconstruction, i.e. the process by which the interpreter makes sense of the speaker's enthymemes. Far from being driven by any pro-social cooperative instinct, interpretative efforts are aimed at extracting valuable information at reasonable costs from available sources. Thus, there is a tension between parsimony and charity, insofar as the former is a non-social constraint for self-regulation of one's behaviour, whereas the latter implies a pro-social attitude. We will argue that some versions of charity are untenable for enthymeme interpretation, while others are compatible with the view defended here, but still require parsimony to expose the ultimate reasons upon which a presumption of fair treatment in enthymeme reconstruction is founded.

I argue that in order to solve the main difficulties confronted by the classical versions of the causal theory of action, it is necessary no just to make room for intentions, considered as irreducible to complexes of beliefs and desires, but also to distinguish among several types of intentions. I present a three-tiered theory of intentions that distinguishes among future-directed intentions, present-directed intentions and motor intentions. I characterize each kind of intention in terms of its functions, its type of content, (...) its dynamics and the rationality and time constraints that bear on it. I then try to show how the difficulties encountered by the causal theory can be solved within this new framework. 1. (shrink)

In this paper I advance a constitutive argument for the authority of rational norms. Because accountability to reasons is constitutive of rational agency and rational norms are implicit in reasons for action and belief, the justification of rational norms is of a piece with the practice of reasoning. Peter Railton has objected that the constitutive view fails to defend the categorical authority of reason over agents. I respond to his objections, arguing that they presuppose a foundationalist conception of justification that (...) demands a ground for reason's authority outside of the practice of reasoning.

The unobservability thesis states that the mental states of other people are unobservable. Both defenders and critics of UT seem to assume that UT has important implications for the mindreading debate. Roughly, the former argue that because UT is true, mindreaders need to infer the mental states of others, while the latter maintain that the falsity of UT makes mindreading inferences redundant. I argue, however, that it is unclear what ‘unobservability’ means in this context. I outline two possible lines of (...) interpretation of UT, and argue that on one of these, UT has no obvious implications for the mindreading debate. On the other line of interpretation, UT may matter to the mindreading debate, in particular if we think of it as a thesis about the possible contents of perceptual experience. The upshot is that those who believe UT has implications for the mindreading debate need to be more specific about how they understand the thesis. (shrink)

Abstract: The intent of this paper is to indicate a development in Sellars' writings which points in another direction than the interpretations offered by Brandom, McDowell, and A. D. Smith. Brandom and McDowell have long claimed to preserve central insights of Sellars's theory of perception; however, they disagree over what exactly these insights are. A. D. Smith has launched a critique of Sellars in chapter 2 of his book The Problem of Perception which is so penetrating that it would tear (...) Sellars' philosophy of perception apart if it were adequate. However, I try to show firstly that Brandom's and McDowell's interpretations are unsatisfying when Sellars' late writings are taking into consideration. And secondly that we can give another interpretation of Sellars that is not vulnerable to some of the problems of which Smith accuses Sellars. (shrink)

Contrary to current individualistic epistemology, Classical rhetoric provides us with a pragmatical and particularly dynamic conception of ‘testimony’ as a source made available for the orator by the particular community in which she acts. In order to count as usable testimony, a testimony to which one could appeal in further communications, any discourse must comply with specific rules of social sanction. A deliberate attention to the social practices in which testimony is given and assessed may offer us a more accurate (...) view of its epistemological role. (shrink)

Contrary to most current epistemologists who concentrate on core cases of rather ‘spontaneous’ trust and belief in the face of assertions, Classical rhetoricians addressed the study of ‘testimony’ as an two-acts phenomenon: that of the ‘disclosure’ of information and that of the ‘appeal’ to its authority in subsequent discursive practices. Moreover, they primarily focused on this second phase as they assumed that it was such argumentative setting that finally gave ‘testimonial’ relevance to the first act. According to this ‘rhetorical’ model, (...) then, it is the dynamics and pragmatics of such complex process that is the core issue regarding ‘testimony’. (shrink)

The paper explores Wittgenstein’s notion of grammar in the sense of a discipline or an activity, as opposed to the object sense of the term (grammar as a body of rules for the use of a language). I argue that the Wittgensteinian activity of grammar consists in giving expression to rules of our language use. It differs from the traditional grammarian’s activity not only in focusing on a different type of rules, but also in that it does not aim at (...) an explicit and exhaustive treatment of a specific domain of language. Instead, Wittgenstein conceives its goal as therapeutic: the dissolution of particular philosophical problems. Further, I attempt to reconcile his seemingly contradictory remarks on the character of grammatical statements, defining the senses in which they respectively can, and cannot, be considered descriptive assertions. I confront G. P. Baker’s and P. M. S. Hacker’s conceptions of the Wittgensteinian grammatical activity and I argue in favour of the former. Finally, I critically examine N. Garver’s claim that Wittgenstein, in his later conception of philosophy as grammar, succeeded in formulating a successfully self-referential criterion of philosophical critique. I also argue that grammatical activity, despite Wittgenstein’s overt commitment, is in fact not the only method of his later philosophy. (shrink)

In The Enigma of Reason, Mercier and Sperber (M&S) present and defend their interactionist account of reason. In this piece, I discuss briefly the points of agreement between M&S and myself and, more extensively, the points of disagreement, most of which pertain to details of the evolutionary components of their account. I discuss in particular the purported modular nature of reason; their account of myside bias as an optimum/adaptation; and the claim that reason thus construed must be an individual‐level and (...) not a group‐level adaptation. In the final section, I offer brief considerations on an alternative account of reasoning, where the focus is on how sociocultural environments may tune the social production and evaluation of arguments.

This article focuses on Jonathan Berg’s Theory of Direct Belief as presented in his 2012 book Direct Belief. An Essay on the Semantics, Pragmatics, and Metaphysics of Belief. After regimenting Berg’s key theses and discussing the sources of their general unpopularity, I proceed to reconstruct Berg’s book-length argument for his conclusions. I here make explicit that Berg relies on a range of strong meta-semantic principles and assumptions. I conclude that even if Berg has brought considerable methodological rigor to the on-going (...) debate over the semantics of natural language attitude ascriptions, and has proposed an elegant and consistent theory, he has not offered compelling reasons to accept his preferred methodological constraints in light of the difficulties, which those constraints impose upon attitude ascription semantics.

Resolution-oriented dialogue has a normative structure that is largely subject to theoretical explication. This paper develops a simple model that sheds light on how moves in a reason-giving game alter the distribution of discursive commitments and entitlements. By clarifying the practice of deontic scorekeeping, we can enhance our collective capacity to resolve conflicts dialogically.

Abstract This paper discusses the semantic theory presented in Robert Brandom’s Making It Explicit . I argue that it is best understood as a special version of dynamic semantics, so that these semantics by themselves offer an interesting theoretical alternative to more standard truth-conditional theories. This reorientation also has implications for more foundational issues. I argue that it gives us the resources for a renewed argument for the normativity of meaning. The paper ends by critically assessing the view in both (...) its development and motivations.

Perceptual processes differ from cognitive, this paper argues, in functioning to be causally controlled by proximal stimuli, and being modular, at least in a modest sense that excludes their being isotropic in Jerry Fodor's sense. This claim agrees with such theorists as Jacob Beck and Ben Phillips that a function of stimulus-control is needed for perceptual status. In support of this necessity claim, I argue, inter alia, that E.J. Green's recent architectural account misclassifies processes deploying knowledge of grammar as perceptual. (...) _Pace_ Beck and Phillips, however, I argue a function of stimulus-control is insufficient for perceptual as opposed to cognitive status. One consideration in favour of such insufficiency, noted but (I argue) not convincingly rebutted by these theorists, concerns perpetually grounded demonstrative thought. Two other considerations trade on the fact that a function of stimulus-control can arise not from blind nature but intentional design or social institutions, where so-functioning processes may but need not be perceptual. I offer two cases where such processes are cognitive, viz. skilful play-by-play announcing of ongoing events, and voluntary visualizing of ongoing events under the guidance of apt play-by-play announcements, dubbed announcement-driven visualizing (ADV). The cognitive status of these three diverse phenomena cannot be explained by an absence of a perception-like representational format or content (for ADV has such) or by a presence of personal-level mental states causally mediating between stimuli and outputs (for perception has such). A bettter explanation invokes, I argue, the non-modular character of the generating process. (shrink)

This paper attempts to describe and address a specific puzzle related to compositionality in artificial networks such as Deep Neural Networks and machine learning in general. The puzzle identified here touches on a larger debate in Artificial Intelligence related to epistemic opacity but specifically focuses on computational applications of human level linguistic abilities or properties and a special difficulty with relation to these. Thus, the resulting issue is both general and unique. A partial solution is suggested.

The aim of this paper is to discuss a basic assumption tacitly shared by many philosophers of mind and language: that whatever can be meant, can be said. It specifically targets John Searle's account of this idea, focusing on his Principle of Expressibility . In the first part of the paper, PE is exposed underlining its analyticity and its relevance for the philosophy of language , mind , society and action . In the critical part, the notion of Background is (...) taken into account in order to re-evaluate two basic distinctions: the one between sentence and utterance meanings , and the one between native and type speakers . PE is reconsidered in the light of the previous arguments as a methodological strategy that does not prevent uses of language from eventual semantic excesses and deficits , and a complementary Principle of Expression Fallibility is finally proposed.

Lewis Carroll's famous puzzle leads to an explanatory challenge: what must we know to grasp the logical necessity of deductive arguments? This paper argues that intellectualism lacks a philosophically satisfying explanation to that puzzle.

This paper revisits the conception of intelligence and understanding as embodied in the Turing Test. It argues that a simple system of meaning relations drawn from words/lexical items in a natural language and framed in terms of syntax-free relations in linguistic texts can help ground linguistic inferences in a manner that can be taken to be 'understanding' in a mechanized system. Understanding in this case is a matter of running through the relevant inferences meaning relations allow for, and some of (...) these inferences are plain deductions and some can serve to act as abductions. Understanding in terms of meaning relations also supervenes on linguistic syntax because such understanding cannot be simply reduced to syntactic relations. The current approach to meaning and understanding thus shows that this is one way, if not the only way, of framing Alan Turing's original insight into the nature of thinking in computing systems.

We begin with a puzzle: why do some know-how attributions entail ability attributions while others do not? After rejecting the tempting response that know-how attributions are ambiguous, we argue that a satisfactory answer to the puzzle must acknowledge the connection between know-how and concept possession (specifically, reasonable conceptual mastery, or understanding). This connection appears at first to be grounded solely in the cognitive nature of certain activities. However, we show that, contra anti-intellectualists, the connection between know-how and concept possession can (...) be generalized via reflection on the cognitive nature of intentional action and the potential of certain misunderstandings to undermine know-how even when the corresponding abilities and associated propositional knowledge are in place. Such considerations make explicit the intimate relation between know-how and understanding, motivating a general intellectualist analysis of the former in terms of the latter. (shrink)

This paper analyses the relatively neglected topic of hierarchy in the philosophical foundation of human rights. It develops a transcendental-discursive approach. This approach develops the idea that all human rights could be derived from a small set of fundamental rights that are interconnected and that incorporate all ulterior possible specific rights. This set is then applied to an analysis of human rights as they have been formulated in the Universal Declaration of Human Rights. The claim is that this prior set (...) of transcendental rights is discursively implied whenever we talk about human rights. Thinking about the hierarchy of rights pragmatically means thinking about prioritising their implementation. Some consequences for practical philosophy and politics concerning the role of states, enterprises and world citizenship are then discussed. (shrink)

It has been widely argued that words are analogous to species such that words, like species, are natural kinds. In this paper, I consider the metaphysics of word-kinds. After arguing against an essentialist approach, I argue that word-kinds are homeostatic property clusters, in line with the dominant approach to other biological and psychological kinds.

In this paper I provide a theory of the speech act of assertion according to which assertion is a species of joint action. In doing so I rely on a theory of joint action developed in more detail elsewhere. Here we need to distinguish between the genus, joint action, and an important species of joint action, namely, what I call joint epistemic action. In the case of the latter, but not necessarily the former, participating agents have epistemic goals, e.g., the (...) acquisition of knowledge. It is joint epistemic action that assertion is a species of. (shrink)

Pippin, Pinkard and Brandom are rightly seen as representatives of a distinct approach in contemporary Hegel scholarship. Still, their interpretations diverge due to different definitions and uses of conceptions of discursive practice. We focus on three ways in which such definitions and uses bear on their interpretations. First, while Lumsden has recently criticized Pinkard and Brandom for ‘discursive bias’ in their accounts of the contestation and upheaval of normative authority in Hegel’s Phenomenology, we note that Pinkard distinguishes between various modes (...) of reason-giving, and we argue that a further qualification of interdependencies between these modes may support his interpretation against such criticism. Second, Pinkard and Pippin have recently criticized Brandom’s conception of discursive score-keeping practice, and Pippin in particular has argued that the latter rests on an individualistic reductionism about content foreign to Hegel. However, we find that the real issue is that the modes of methodological abstraction and idealization assumed for Brandom’s conception of discursive practice leave out of account the historical alteration as well as the institutional embodiment of normative authority as emphasized by Pippin and Pinkard. Third, while Pippin and Pinkard both make Hegel’s notion of modern ethical life bear on a conception of practical rationality, their uses of a conception of discursive practice in such an undertaking betray divergent conceptions of the sociality of rational agents.

Inspired by two-dimensional modal logic, some have sought to provide analyses of the notion of the contingent a priori which identify the a priori with truths which have a necessary diagonal. I argue that these analyses fail insofar as they miss the crucial epistemic aspect of the a priori. Augmenting these analyses with specifically epistemic accounts might be possible, but the interest would then reside in these epistemic accounts of the a priori and not in the formal models.

I offer an argument for what mental action may be like in nonhuman animals. Action planning is a type of mental action that involves a type of intention. Some intentions are the causal mental antecedents of proximal mental actions, and some intentions are the causal mental antecedents of distal mental actions. The distinction between these two types of “plan-states” is often spelled out in terms of mental content. The prominent view is that while proximal mental actions are caused by mental (...) states with nonconceptual content, distal mental actions are caused by mental states with conceptual content. I argue that, when we are investigating animal cognition, we need a nonconceptual account for the content of intentions involved in mental actions such as action planning: non-immediate intentions. This in order to defend the claim that creatures that lack conceptual capacities are capable of entertaining plan-states, and thus of exercising mental agency in the form of action planning.

Against the background of recent developments in neuroscience, the paper shows how, for Hegel, the theoretical, practical and evaluative functions of the mind are grounded in something like a natural normativity, based on the interaction of the body's inner world with the outer world. These forms of organic homeostasis are the basis for further kinds and levels of norms, and deviations from these norms, which result in mental pathologies, provide insights into the complexity of spirit.

This is a critical discussion of selected chapters of the first volume of Scott Soames's _Philosophical Analysis in the Twentieth Century. It is argued that this volume falls short of the minimal standards of scholarship appropriate to a work that advertises itself as a history, and, further, that Soames's frequent heuristic simplifications and distortions, since they are only sporadically identified as such, are more likely to confuse than to enlighten the student. These points are illustrated by reference to Soames's discussions (...) of Russell's logical system and the place of the theory of descriptions in his ontological development. It is then argued that Soames's interpretation of the point of G. E. Moore's famous 'proof' of an external world, while not straightforwardly undermined by the textual evidence, is nonetheless questionable, and plausibly overlooks what is novel in Moore's discussion. This, it is argued, in his attempt to offer a common sense 'refutation of idealism', rather than (as is more commonly supposed) an antiskeptical argument 'from differential certainty'. (shrink)

Many interpreters have noted that §§138–242 of Wittgenstein's Philosophical Investigations is dominated by an attack on a platonist or classical realist conception of rules and meaning. In this paper, I address the lack of clarity that still exists concerning the nature and strength of the arguments in those sections. I argue that Wittgenstein's attack is genuinely compelling if viewed as an intricate reductio ad absurdum argument that runs all the way through §§138–201. On my reading, the well-known regress-of-interpretations argument is (...) merely one stage in the overall reductio and is not sufficient on its own to generate the rule-following paradox. (shrink)

The overwhelming consensus amongst epistemologists is that there is no salient epistemological difference between the addressees of a speaker’s testimony and non-addressees. I argue that this overwhelming consensus is mistaken. Addressees of a speaker’s testimony are entitled to pass the epistemic buck or defer justificatory responsibility for their beliefs back to the testimonial speaker, while non-addressees are not. I then develop a provisional account of address that is in a position to mark this epistemic distinction between addressees and non-addressees.

According to so-called “credit views of knowledge,” knowledge is an achievement of an epistemic agent, something for which an agent is creditable or responsible. One influential criticism of the credit view of knowledge holds that the credit view has difficulty making sense of knowledge acquired from testimony. As Jennifer Lackey has argued, in many ordinary cases of the acquisition of testimonial knowledge, if anyone deserves credit for the truth of the audience’s belief it is the testimonial speaker rather than the (...) audience, and so it isn’t clear that testimonial knowers are appropriately creditable for the truth of their beliefs. I argue that the credit view of knowledge can be saved from Lackey’s objection by focusing on the way in which testimonial knowledge is the result of an essentially social epistemic ability. While there is indeed a sense in which a testimonial knower is only partially epistemically responsible for her testimonial belief, this is consistent with the truth of her belief being creditable to her in another sense. The truth of her belief is most saliently explained by, and hence is fully creditable to, an essentially social epistemic ability, an ability that is only partially seated in the knowing subject. (shrink)

Participants on both sides of the contemporary debate between reductionism and anti-reductionism about testimony commonly describe testimonial knowledge as knowledge acquired at second hand. I argue that fully appreciating the distinctive sense in which testimonial knowledge is secondhand supports anti-reductionism over reductionism but also that it supports a particular kind of anti-reductionism very different from that typically offered in the literature. Testimonial knowledge is secondhand in the demanding sense of being justified by the authority of a speaker where this requires (...) that epistemic responsibility for meeting challenges to the audience's testimonial knowledge is shared between speaker and audience. The epistemic credentials of testimonial knowledge are in this sense importantly interpersonal. (shrink)

A speaker’s retraction of her own previous testimony serves to defeat the reason for belief provided by her testimony in a distinctive way. In telling an addressee that p, the speaker purports to settle for the addressee the question whether p. In retracting her testimony, the speaker then revokes her settling of this question for the addressee, cancelling the addressee’s entitlement to pass the epistemic buck back to her should the content of her belief be challenged, and this entitlement is (...) cancelled even if the addressee has good reason to believe that the speaker’s retraction is misguided or mistaken. Deferentially believing a speaker and allowing them to settle a theoretical question thus has a distinctive temporal and interpersonal character, requiring the addressee to assume that both she herself and the speaker will continue to do their part in the joint activity that is the addressee’s holding p true.

This is a survey of recent debates concerning the normativity of belief. We explain what the thesis that belief is normative involves, consider arguments for and against that thesis, and explore its bearing on debates in metaethics.
