Reasoning, Misc

Counterfactual reasoning has always played a role in human life. We ask questions like, “Could it have been different?”, “Under which conditions might/would it have been different?”, “What would have happened if…?” If we don’t find an answer, i.e. what we accept as an answer, we may start reasoning. Reasoning means introducing still new information/assumptions, new questions, new answers to new questions etc. From a formal point of view, it may be compared with stepwise moving towards a destination in a (...) path-system, in which you never fully have an overview. In this way, reasoning is an activity, with its own rationale, which will be studied from the agent’s own perspective. Questions include: What are the conditions where asking that specific question, or introducing this information/assumption, etc. will count as a reasonable step or progress towards the answer of the initial question? What makes this step more reasonable than another? (shrink)

Different people reason differently, which means that sometimes they reach different conclusions from the same evidence. We maintain that this is not only natural, but rational. In this essay we explore the epistemology of that state of affairs. First we will canvass arguments for and against the claim that rational methods of reasoning must always reach the same conclusions from the same evidence. Then we will consider whether the acknowledgment that people have divergent rational reasoning methods should undermine one’s confidence (...) in one’s own reasoning. Finally we will explore how agents who employ distinct yet equally rational methods of reasoning should respond to interactions with the products of each others’ reasoning. We find that the epistemology of multiple reasoning methods has been misunderstood by a number of authors writing on epistemic permissiveness and peer disagreement. (shrink)

In the wake of 9/11 and the assessment of Iraq's WMD, several inquiries placed the blame primarily on the Intelligence Community. Part of the reform that followed was a codification of analytic tradecraft standards into Intelligence Community Directive (ICD) 203 and the appointment of an analytic ombudsman in the newly created Office of the Director of National Intelligence charged with monitoring the quality of analytic products from across the intelligence community. In this paper we identify three assumptions behind ICD203: (1) (...) tradecraft standards can be employed consistently; (2) tradecraft standards sufficiently capture the key elements of good reasoning; (3) good reasoning leads to more accurate judgments. We then report on two controlled experiments that uncover operational constraints in the reliable application of the ICD203 criteria for the assessment of intelligence products. Despite criticisms of the post-9/11 and post-Iraq reform, our results highlight that ICD203, properly applied, holds potential to improve precision and accountability of intelligence processes and products.

I accomplish two things in this paper. I explain the motivation for including experimental research in philosophical projects on epistemic reasons and the basing relation. And I present the first experimental contributions to these projects. The results from two experiments advance our understanding of the ordinary concepts of reasons and basing and set the stage for further research on the topics. More specifically, the results support a causal theory of the basing relation, according to which reasons are causes, and a (...) dualist theory of epistemic reasons, according to which reasons include both psychological and non-psychological items.

Inferences are familiar movements of thought, but despite important recent work on the topic, we do not yet have a fully satisfying theory of inference. Here I provide a functionalist theory of inference. I argue that the functionalist framework allows us the flexibility to meet various demands on a theory of inference that have been proposed (such as that it must explain inferential Moorean phenomena and epistemological ‘taking’). While also allowing us to compare, contrast, adapt, and combine features of extant (...) theories of inference into one unified theory. In fleshing out the inference role, I also criticize the common assumption that inference requires rule-following. (shrink)

This paper tries to do three things. First, it tries to make it plausible that correct rules of reasoning do not always preserve justification: in other words, if you begin with a justified attitude, and reason correctly from that premise, it can nevertheless happen that you’ll nevertheless arrive at an unjustified attitude. Attempts to show that such cases in fact involve following an incorrect rule of reasoning cannot be vindicated. Second, it also argues that correct rules of reasoning do not (...) even correspond to permissions of “structural rationality”: it is not always structurally permissible to base an attitude on other attitudes from which it follows by correct reasoning. Third, from these observations it tries to build a somewhat positive account of the correctness of rules of reasoning as a more sui generis notion irreducible to either justification or structural rationality. This account vindicates an important unity of theoretical and practical reasoning as well as a qualified version of the thesis that deductive logic supplies correct rules of reasoning. (shrink)

Bayesianism can be characterized as the following twofold position: (i) rational credences obey the probability calculus; (ii) rational learning, i.e., the updating of credences, is regulated by some form of conditionalization. While the formal aspect of various forms of conditionalization has been explored in detail, the philosophical application to learning from experience is still deeply problematic. Some philosophers have proposed to revise the epistemology of perception; others have provided new formal accounts of conditionalization that are more in line with how (...) we learn from perceptual experience. The current investigation argues that Bayesian epistemology is still incomplete; the epistemology of perception and the epistemology of rational reasoning have not been reconciled. (shrink)

Four studies explore the role of perceptual fluency in attenuating bullshit receptivity, or the tendency for individuals to rate otherwise meaningless statements as “profound”. Across four studies, we presented participants with a sample of pseudoprofound bullshit statements in either a fluent or disfluent font and found that overall, disfluency attenuated bullshit receptivity while also finding little evidence that this effect was moderated by cognitive thinking style. In all studies, we measured participants’ cognitive reflection, need for cognition, faith in intuition, and (...) superstitious beliefs. Superstition strongly predicted bullshit receptivity regardless of fluency. Inconclusive results were found for the remaining scales. Potential links for the role of perceptual disfluency in promoting analytic thinking are discussed. (shrink)

According to the Reasoning View, a normative reason to φ is a premise in a pattern of sound reasoning leading to the conclusion to φ. But how should the Reasoning View account for reasons that are outweighed? One very promising proposal is to appeal to defeasible reasoning. On this proposal, when a reason is outweighed, the associated pattern of sound reasoning is defeated. Both Jonathan Way and Sam Asarnow have recently developed this idea in different ways. I argue that this (...) appeal to defeasible reasoning faces a challenge, since reasons can be both outweighed and disabled. Way's view generates good predictions about outweighed reasons, but not about disabled reasons. Asarnow's view generates good predictions about disabled reasons, but not about outweighed reasons. We want a version of the Reasoning View that can generate good predictions about both. I present a version of the Reasoning View that can meet the challenge. (shrink)

People reason not only in beliefs, but also in intentions, preferences, and other attitudes. They form preferences from existing preferences, or intentions from existing beliefs and intentions, and so on. This often involves choosing between rival conclusions. Building on Broome (Rationality through reasoning, Hoboken, Wiley. https://doi.org/10.1002/9781118609088, 2013) and Dietrich et al. (J Philos 116:585–614. https://doi.org/10.5840/jphil20191161138, 2019), we present a philosophical and formal analysis of reasoning in attitudes, with or without facing choices in reasoning. We give different accounts of choosing, in (...) terms of a conscious activity or a partly subconscious process. Reasoning in attitudes differs fundamentally from reasoning _about_ attitudes, a form of theoretical reasoning in which one discovers rather than forms attitudes. We show that reasoning in attitudes has standard formal properties (such as monotonicity), but is indeterministic, reflecting choice in reasoning. Like theoretical reasoning, it need not follow logical entailment, but for a more radical reason, namely indeterminism. This makes reasoning in attitudes harder to model logically than theoretical reasoning. But it can be studied abstractly, using indeterministic consequence operators. (shrink)

While many authors distinguish belief from acceptance, it seems almost universally agreed that no similar distinction can be drawn between degrees of belief, or credences, and degrees of acceptance. I challenge this assumption in this paper. Acceptance comes in degrees and acknowledging this helps to resolve problems in at least two philosophical domains. Degrees of acceptance play vital roles when we simplify our reasoning, and they ground the common ground of a conversation if we assume context probabilism, i.e., that the (...) common ground must be represented with probability spaces rather than possible worlds.

Alex Worsnip's recent book, Fitting Things Together: Coherence and the Demands of Structural Rationality, provides a sustained, wide-ranging defence of dualism.

Virtue theories of argumentation (VTA) emphasize the roles arguers play in the conduct and evaluation of arguments, and lay particular stress on arguers’ acquired dispositions of character, that is, virtues and vices. The inspiration for VTA lies in virtue epistemology and virtue ethics, the latter being a modern revival of Aristotle’s ethics. Aristotle is also, of course, the father of Western logic and argumentation. This paper asks to what degree Aristotle may thereby be claimed as a forefather by VTA.

What is the relevance of ideals for determining virtuous argumentative practices? According to Bailin and Battersby (2016), the telos of argumentation is to improve our cognitive systems, and adversariality plays no role in ideally virtuous argumentation. Stevens and Cohen (2019) grant that ideal argumentation is collaborative, but stress that imperfect agents like us should not aim at approximating the ideal of argumentation. Accordingly, it can be virtuous, for imperfect arguers like us, to act as adversaries. Many questions are left unanswered (...) by both camps. First, how do we conceptualize an ideal and its approximation? Second, how can we determine what is the ideal of argumentation? Third, can we extend Stevens and Cohen’s anti-approximation argument beyond virtue theory? In order to respond to these questions, this paper develops a second-best perspective on ideal argumentation. The Theory of the Second Best is a formal contribution to the field of utility (or welfare) optimization. Its main conclusion is that, in non-ideal circumstances, approximating ideals might be suboptimal. (shrink)

Argument mapping is a way of diagramming the logical structure of an argument to explicitly and concisely represent reasoning. The use of argument mapping in critical thinking instruction has increased dramatically in recent decades. This paper overviews the innovation and provides a procedural approach for new teaches wanting to use argument mapping in the classroom. A brief history of argument mapping is provided at the end of this paper.

I argue that we can reason not only to new beliefs but to basically any change in attitude we can think of, including the abandonment of belief (contra John Broome), the acquisition of non-belief attitudes like relief and admiration, and the elimination of the same. To argue for this position, which I call generalism, I defend a sufficient condition on reasoning, roughly that we can reason to any change in attitude that is expressed by the conclusion of an argument we (...) can be convinced by. I then produce examples of such arguments, and argue that they are indeed arguments. To produce such examples of the elimination of non-doxastic attitudes, I develop the idea of a state of attitudinal constraint acceptance, and show how it is useful for solving this problem, and useful in other parts of philosophy as well.

Many hold that theoretical reasoning aims at truth. In this paper, I ask what it is for reasoning to be thus aim-directed. Standard answers to this question explain reasoning’s aim-directedness in terms of intentions, dispositions, or rule-following. I argue that, while these views contain important insights, they are not satisfactory. As an alternative, I introduce and defend a novel account: reasoning aims at truth in virtue of being the exercise of a distinctive kind of cognitive power, one that, unlike ordinary (...) dispositions, is capable of fully explaining its own exercises. I argue that this account is able to avoid the difficulties plaguing standard accounts of the relevant sort of mental teleology. (shrink)

The way in which philosophers have thought about the scientific method and the nature of good scientific reasoning over the last few centuries has been consistently and heavily influenced by the examples set by physics. The astounding achievements of 19th and 20th century physics demonstrated that physicists had successfully identified methodologies and reasoning patterns that were uniquely well suited to discovering fundamental truths about the natural world. Inspired by this success, generations of philosophers set themselves the goal of taxonomising, codifying, (...) formalising and evaluating these reasoning patterns. Many will concede that this has been a tremendously fruitful exercise that has served both to illuminate characteristic methodological and epistemological features of the physical sciences, and to inform the way that philosophers think about the epistemic ideals served by science more generally. However, as has been widely noted, the great challenges confronted by contemporary physics have led to a number of fundamental shifts in the way that physicists formulate, assess and apply their theories of the physical world. The most prominent examples of this trend occur in the realm of theoretical high energy physics, where many of the most influential theories advocated by physicists lie beyond the reach of extant experimental methods, and are therefore extremely difficult to test empirically. The fact that whole communities of physicists have devoted so much time and effort to evaluating theories that are largely disconnected from experiments and empirical testing suggests that existing philosophical accounts of the epistemology of physics, based as they are on a broadly empiricist conception of physics, are no longer completely apt, or are at least somewhat out of date. This in turn suggests that it is time for philosophers to redirect their attention towards the characteristic reasoning strategies at play in contemporary physics. As well as clarifying the epistemic structure of 21st century physics and providing new stimulation for general debates surrounding the epistemology of science, this will also allow more philosophers to confront and engage with the existential methodological debates currently raging within physics. There is currently intense and wide spread disagreement surrounding what kinds of reasoning strategies can legitimately be employed in the assessment of competing physical theories and research programs. This special issue aims to facilitate the further engagement of philosophers in this crucial debate by collecting eight contributions that both highlight the deep philosophical issues at stake in debates surrounding the proper methodology for theory assessment in physics, and present novel philosophical perspectives on specific reasoning strategies in the physical sciences.

The core of Zimmerman’s picture posits an inverse correlation between an action’s automaticity and belief’s role in the action’s execution. This proposal faces serious problems. First, high-attention, high-control actions don’t seem to heighten awareness of one’s beliefs. Second, low-attention, low-control actions are caused by the same states at play when executing high-attention, high-control actions, in which case there is no ontological difference in the states involved in these behaviors. Third, on Zimmerman’s view it is unclear what it is for a (...) state to be involved in behaviors at all, as the basic realist response—that beliefs cause behavior—is unavailable to a Zimmerman-style pragmatist. Lastly, if Zimmerman's view were right and low-level behaviors weren't caused by beliefs, then we should turn our attention to those states instead, as most of our behavior isn’t executed under conditions of high control and attention.

Resource rationality may explain suboptimal patterns of reasoning; but what of “anti-Bayesian” effects where the mind updates in a direction opposite the one it should? We present two phenomena — belief polarization and the size-weight illusion — that are not obviously explained by performance- or resource-based constraints, nor by the authors’ brief discussion of reference repulsion. Can resource rationality accommodate them?

Es mi afirmación que la tabla de intencionalidad (racionalidad, mente, pensamiento, lenguaje, personalidad, etc.) que presenta prominentemente aquí describe más o menos con precisión, o al menos sirve como heurística para, cómo pensamos y nos comportamos, y por lo tanto no abarca simplemente filosofía y psicología, sino todo lo demás (historia, literatura, matemáticas, política, etc.). Tenga en cuenta especialmente que la intencionalidad y racionalidad como yo (junto con Searle, Wittgenstein y otros) lo veo, incluye tanto el Sistema Linguístico deliberativo consciente (...) 2 como las acciones o reflejos inconscientes automatizados del Sistema 1 automatizado. -/- Proporciono una encuesta crítica de algunos de los principales hallazgos de dos de los estudiantes más eminentes de comportamiento de los tiempos modernos, Ludwig Wittgenstein y John Searle, sobre la estructura lógica de la intencionalidad (mente, lenguaje, comportamiento), tomando como punto de partida el descubrimiento fundamental de Wittgenstein -que todos los problemas verdaderamente "filosóficos" son los mismos—confusiones sobre cómo usar el lenguaje en un contexto particular, y por lo tanto todas las soluciones son las mismas— mirando cómo se puede utilizar el lenguaje en el contexto en cuestión para que sus condiciones de verdad (Condiciones de Satisfacción o COS) son claras. El problema básico es que uno puede decir cualquier cosa, pero no se puede significar (indicar COS claro para) cualquier expresión arbitraria y significado sólo es posible en un contexto muy específico. Analizo varios escritos por y sobre ellos desde la perspectiva moderna de los dos sistemas de pensamiento (popularizados como 'pensar rápido, pensar lento'), empleando una nueva tabla de intencionalidad y nueva nomenclatura de sistemas duales. Demuestro que esta es una heurística poderosa para describir el comportamiento. -/- Por lo tanto, todo comportamiento está íntimamente conectado si uno toma el punto de vista correcto. La Ilusión Fenomenológica (olvido a nuestro Sistema automatizado 1) es universal y se extiende no sólo a lo largo de la filosofía, sino a lo largo de la vida. Estoy seguro de que Chomsky, Obama, Zuckerberg y el Papa serían incrédulos si se les dijera que sufren del mismo problema que Hegel, Husserl y Heidegger, (o que difieren sólo en grado de los adictos a las drogas y el sexo en estar motivados por la estimulación de sus cortices frontales por la entrega de dopamina (y más de 100 otros productos químicos) a través del tegmentum ventral y el núcleo accumbens),pero es claramente cierto.

This book is concerned with the conditions under which epistemic reasons provide justification for beliefs. The author draws on metaethical theories of reasons and normativity and then applies his theory to various contemporary debates in epistemology. In the first part of the book, the author outlines what he calls the dispositional architecture of epistemic reasons. The author offers and defends a dispositional account of how propositional and doxastic justification are related to one another. He then argues that the dispositional view (...) has the resources to provide an acceptable account of the notion of the basing relation. In the second part of the book, the author examines how his theory of epistemic reasons bears on the issues involving perceptual reasons. He defends dogmatism about perceptual justification against conservatism and shows how his dispositional framework illuminates certain claims of dogmatism and its adherence to justification internalism. Finally, the author applies his dispositional framework to epistemological topics including the structure of defeat, self-knowledge, reasoning, emotions and motivational internalism. The Dispositional Architecture of Epistemic Reasons demonstrates the value of employing metaethical considerations for the justification of beliefs and propositions. It will be of interest to scholars and advanced students working in epistemology and metaethics. (shrink)

We are justified in employing the rule of inference Modus Ponens (or one much like it) as basic in our reasoning. By contrast, we are not justified in employing a rule of inference that permits inferring to some difficult mathematical theorem from the relevant axioms in a single step. Such an inferential step is intuitively “too large” to count as justified. What accounts for this difference? In this paper, I canvass several possible explanations. I argue that the most promising approach (...) is to appeal to features like usefulness or indispensability to important or required cognitive projects. On the resulting view, whether an inferential step counts as large or small depends on the importance of the relevant rule of inference in our thought. (shrink)

Electrical brain activity modulation in terms of changes in its intensity and spatial distribution is a function of age and task demand. However, the dynamics of brain modulation is unknown when it depends on external factors such as training. The aim of this research is to verify the effect of deductive reasoning training on the modulation in the brain activity of healthy younger and older adults ( (mean age of 21 ± 3.39) and (mean age of 68.92 ± 5.72)). The (...) analysis reveals the benefits of training, showing that it lowers cerebral activation while increasing the number of correct responses in the trained reasoning task (). The brain source generators were identified by time-averaging low-resolution brain electromagnetic tomography (sLORETA) current density images. In both groups, a bilateral overactivation associated with the task and not with age was identified. However, while the profile of bilateral activation in younger adults was symmetrical in anterior areas, in the older ones, the profile was located asymmetrically in anterior and posterior areas. Consequently, bilaterality may be a marker of how the brain adapts to maintain cognitive function in demanding tasks in both age groups. However, the differential bilateral locations across age groups indicate that the tendency to brain modulation is determined by age. (shrink)

This textbook is not a textbook in the traditional sense. Here, what we have attempted is compile a set of assignments and exercise that may be used in critical thinking courses. To that end, we have tried to make these assignments as diverse as possible while leaving flexibility in their application within the classroom. Of course these assignments and exercises could certainly be used in other classes as well. Our view is that critical thinking courses work best when they are (...) presented as skills based learning opportunities. We hope that these assignments speak to that desire and can foster the kinds of critical thinking skills that are both engaging and fun Please feel free to contact us with comments and suggestions. We will strive to correct errors when pointed out, add necessary material, and make other additional and needed changes as they arise. Please check back for the most up to date version.

Background. The events of 9/11 and the October 2002 National Intelligence Estimate on Iraq's Continuing Programs for Weapons of Mass Destruction precipitated fundamental changes within the US Intelligence Community. As part of the reform, analytic tradecraft standards were revised and codified into a policy document – Intelligence Community Directive (ICD) 203 – and an analytic ombudsman was appointed in the newly created Office for the Director of National Intelligence to ensure compliance across the intelligence community. In this paper we investigate (...) the untested assumption that the ICD203 criteria can facilitate reliable evaluations of analytic products. Method. Fifteen independent raters used a rubric based on the ICD203 criteria to assess the quality of reasoning of 64 analytical reports generated in response to hypothetical intelligence problems. We calculated the intra-class correlation coefficients for single and group-aggregated assessments. Results. Despite general training and rater calibration, the reliability of individual assessments was poor. However, aggregate ratings showed good to excellent reliability. Conclusions. Given that real problems will be more difficult and complex than our hypothetical case studies, we advise that groups of at least three raters are required to obtain reliable quality control procedures for intelligence products. Our study sets limits on assessment reliability and provides a basis for further evaluation of the predictive validity of intelligence reports generated in compliance with the tradecraft standards.

What makes the difference between good and bad reasoning? In this paper we defend a novel account of good reasoning—both theoretical and practical—according to which it preserves fittingness or correctness: good reasoning is reasoning which is such as to take you from fitting attitudes to further fitting attitudes, other things equal. This account, we argue, is preferable to two others that feature in the recent literature. The first, which has been made prominent by John Broome, holds that the standards of (...) good reasoning derive from rational requirements. The second holds that these standards derive from reasons. We argue that these accounts face serious difficulties in correctly distinguishing good from bad reasoning, and in explaining what's worthwhile about good reasoning. We then propose our alternative account and argue that it performs better on these counts. In the final section, we develop certain elements of the account in response to some possible objections.

Accounts of arguments from expert opinion take it for granted that expert judgments count as (defeasible) evidence for propositions, and so an argument that proceeds from premises about what an expert judges to a conclusion that the expert is probably right is a strong argument. In Mizrahi (2013), I consider a potential justification for this assumption, namely, that expert judgments are significantly more likely to be true than novice judgments, and find it wanting because of empirical evidence suggesting that expert (...) judgments under uncertainty are not significantly more likely to be true than novice judgments or even chance. In this paper, I consider another potential justification for this assumption, namely, that expert judgments are not influenced by the cognitive biases novice judgments are influenced by, and find it wanting, too, because of empirical evidence suggesting that experts are vulnerable to pretty much the same cognitive biases that novices are vulnerable to. If this is correct, then the basic assumption at the core of accounts of arguments from expert opinion, namely, that expert judgments count as (defeasible) evidence for propositions, remains unjustified.

In this paper I deal with epistemological issues that stem from the hypothesis that reasoning is not only a means of transmitting knowledge from premise-beliefs to conclusion-beliefs, but also a primary source of knowledge in its own right. The idea is that one can gain new knowledge on the basis of suppositional reasoning. After making some preliminary distinctions, I argue that there are no good reasons to think that purported examples of knowledge grounded on pure reasoning are just examples of (...) premise-based inferences in disguise. Next, I establish what kinds of true propositions can to a first approximation be known on the basis of pure reasoning. Finally, I argue that beliefs that are competently formed on the basis of suppositional reasoning satisfy both externalist and internalist criteria of justification. (shrink)

Hay doble pulsión en el centro de la discusión del razonamiento deductivo. Una conduce aparentemente a la abstracción y dominios arbitrarios, mientras que la otra conduce a la concreción y la dependencia del contenido. El objetivo de esta investigación es diseñar, aplicar y validar un instrumento de evaluación que nos permita corroborar si el razonamiento deductivo maneja reglas lógicas o contenidos.

This tribute to the breadth and influence of Trudy Govier’s philosophical work begins with her early scholarship in argumentation theory, paying special attention to its pedagogical expression. Most people first encounter Trudy Govier’s work and many people only encounter it through her textbooks, especially A Practical Study of Argument, published in many editions. In addition to the work on argumentation that has continued throughout her career, much of Govier’s later work addresses social philosophy and the problems of trust and response (...) to moral wrongs. The introduction by Catherine Hundleby situates Govier’s research along the path of her unusual academic life. While following the timeline of Govier’s research publication, in this collection the authors build on her work and suggest certain new connections between her argumentation theory and social philosophy. A Practical Study of Argument, first published in 1985, situates Govier among a distinct segment of informal logicians whose concerns about teaching reasoning to post-secondary students orient their research, Takuzo Konishi argues. Moira Kloster evaluates Govier’s progress in the challenge of providing critical thinking education to diverse and changing social contexts. Shifting gears to social philosophy but still addressing education, Laura Elizabeth Pinto explores the significance of Govier’s work on trust for explaining the problem of “audit culture” for teaching. At the centre of this volume, social philosophy receives an abstract meta-ethical defense from Linda Radzik. Moving solidly into the domain of normative social philosophy, Alice MacLachlan reconsiders Govier’s condemnation of revenge by viewing it as a form of moral address, but she notes how revenge as an act of communication contrasts with argumentation in lacking the respect that Govier maintains is intrinsic to argumentation. MacLachlan ultimately agrees that revenge is morally indefensible. The practical challenges of addressing others in the aftermath of wrongdoing, especially in public contexts, can make it difficult to distinguish between victims and combatants or wrongdoers, Alistair Little and Wilhelm Verwoerd explain, and Kathryn Norlock argues that forgiveness is psychologically vexed too. People may recognize transformation to be in principle possible for all people, Norlock argues, and yet we may find the evidence regarding some particular evildoer sufficient to count that person as an exception. Finally Govier responds to the various papers. (shrink)

In this chapter, we outline the range of argument forms involving causation that can be found in everyday discourse. We also survey empirical work concerned with the generation and evaluation of such arguments. This survey makes clear that there is presently no unified body of research concerned with causal argument. We highlight the benefits of a unified treatment both for those interested in causal cognition and those interested in argumentation, and identify the key challenges that must be met for a (...) full understanding of causal argumentation.

The justificatory force of empirical reasoning always depends upon the existence of some synthetic, a priori justification. The reasoner must begin with justified, substantive constraints on both the prior probability of the conclusion and certain conditional probabilities; otherwise, all possible degrees of belief in the conclusion are left open given the premises. Such constraints cannot in general be empirically justified, on pain of infinite regress. Nor does subjective Bayesianism offer a way out for the empiricist. Despite often-cited convergence theorems, subjective (...) Bayesians cannot hold that any empirical hypothesis is ever objectively justified in the relevant sense. Rationalism is thus the only alternative to an implausible skepticism. (shrink)

Persuasion is a special aspect of our social and linguistic practices – one where an interlocutor, or an audience, is induced, to perform a certain action or to endorse a certain belief, and these episodes are not due to the force of the better reason. When we come near persuasion, it seems that, in general, we are somehow giving up factual discourse and the principles of logic, since persuading must be understood as almost different from convincing rationally. Sometimes, for example, (...) we can find persuasion a political speech that relies on our feelings, emotions and values, but we can also find a persuasive person a dodger, busy in his own questionable activities that are intentionally performed in order to mislead and manipulate other people. However, I do not want to try to define a general notion of persuasion from the beginning. I would rather start with a conception that already has a place, even if controversial, in the philosophical debate. In particular, the version that I have always found particularly provocative is that provided by Wittgenstein’s On Certainty. This peculiar version of the idea of persuasion, which is often associated with the possibility of overcoming deep disagreements, is quite famous in the literature and often understood as indicating certain intrinsic limits of our reason-giving practices. The following are Wittgenstein’s famous remarks on persuasion: -/- 608. Is it wrong for me to be guided in my actions by the propositions of physics? Am I to say I have no good ground for doing so? Isn’t precisely this what we call a ‘good ground’? -/- 609. Suppose we met people who did not regard that as a telling reason. Now, how do we imagine this? Instead of the physicist, they consult an oracle. (And for that we consider them primitive.) Is it wrong for them to consult an oracle and be guided by it? If we call this “wrong” aren’t we using our language-game as a base from which to combat theirs? -/- 611. Where two principles really do meet which cannot be reconciled with one another, then each man declares the other a fool and heretic. -/- 612. I said I would ‘combat’ the other man, – but wouldn’t I give him reasons? Certainly; but how far do they go? At the end of reasons comes persuasion. (Think what happens when missionaries convert natives.) -/- This paper is not devoted, as far as possible, to focus on interpretative matters about Wittgenstein’s late philosophy. Rather, it aims to investigate whether there are problems and incompatibilities between this particular conception of persuasion and our contemporary understanding of our reason-giving practices and of our belief-revision procedures. The first part of this study will be concerned about assessing this conception of persuasion and trying to shed new light on it (and on its consequences); most of the work here is done by looking at some truisms and normative features of our practices regarding the rational updating of our beliefs. It also addresses the question: Is the resistance to reasons of Wittgenstein’s persuasion capable to avoid the strict dynamics of belief revision? The second section of this study concerns the possibility of limiting the scope of this conception of persuasion, thanks to some of our contemporary ways of understanding rational discursive practices (I will focus especially on Robert Brandom’s game of “giving and asking for reasons”). If our rational practices require at least a certain degree of epistemic responsibility, then how is it possible that one invokes the end of reasons (that would explicitly mean giving up this responsibility)? A third section is the attempt, on this basis, to try to revise our contrasting conception(s) of persuasion (with an eye open on the near doxastic territory). Are there other conceptions of persuasion which are more compatible with our rational practices and do not entail any version of the “end of reasons” that are so compatible with our individual and social epistemic responsibility?

Rationalization, in our intended sense of the term, occurs when a person favors a particular conclusion as a result of some factor (such as self-interest) that is of little justificatory epistemic relevance, if that factor then biases the person’s subsequent search for, and assessment of, potential justifications for the conclusion. Empirical evidence suggests that rationalization is common in people’s moral and philosophical thought. We argue that it is likely that the moral and philosophical thought of philosophers and moral psychologists is (...) also pervaded by rationalization. Moreover, although rationalization has some benefits, overall it would be epistemically better if the moral and philosophical reasoning of people, including professional academics, were not as heavily influenced by rationalization as it likely is. We discuss the significance of our arguments for cognitive management and epistemic responsibility. (shrink)

In this study we investigate the influence of reason-relation readings of indicative conditionals and ‘and’/‘but’/‘therefore’ sentences on various cognitive assessments. According to the Frege-Grice tradition, a dissociation is expected. Specifically, differences in the reason-relation reading of these sentences should affect participants’ evaluations of their acceptability but not of their truth value. In two experiments we tested this assumption by introducing a relevance manipulation into the truth-table task as well as in other tasks assessing the participants’ acceptability and probability evaluations. Across (...) the two experiments a strong dissociation was found. The reason-relation reading of all four sentences strongly affected their probability and acceptability evaluations, but hardly affected their respective truth evaluations. Implications of this result for recent work on indicative conditionals are discussed. (shrink)

This article is a general introduction to the psychology of reasoning. Specifically, it focuses on the dual process theory of human cognition. Proponents of the said two-system view hold that human cognition involves two processes (viz., System 1 and System 2). System 1 is an automatic, intuitive thinking process where judgments and reasoning rely on fast thinking and ready-to-hand data. On the other hand, System 2 is a slow, logical cognitive process where our judgments and reasoning rely on reflective, careful (...) analysis and data evaluation. Supposedly, these two cognitive processes are at play in every thinking task, and they sometimes work together and sometimes go against each other. (shrink)

This paper addresses the extent to which quotidian cognition is like scientific inference by focusing on Jerry Fodor's famous analogy. I specifically consider and rebut a recent attempt made by Tim Fuller and Richard Samuels to deny the usefulness of Fodor's analogy. In so doing, I reveal some subtleties of Fodor's arguments overlooked by Fuller and Samuels and others. Recognizing these subtleties provides a richer appreciation of the analogy, allowing us to gain better traction on the issue concerning the extent (...) to which everyday cognition is like scientific inference. In the end, I propose that quotidian cognition is indeed like scientific inference, but not precisely in the way Fodor claims it is. (shrink)

In Section 1, we make some preliminary remarks about the concept of epis‐ temic entitlement, understood in terms of ex ante rationality. In Section 2, we argue that a certain epistemological view – one according to which ex ante rationality is solely a func- tion of available reasons – is inadequate. In Sections 3-4 we will esh out an alternative view about ex ante rationality, one according to which forming a certain belief is rational for a subject S only when (...) S knows how to reason in a certain way. In Section 5 we explore some consequences of our view and we describe the main challenge that we must meet in future work. (shrink)

According to a family of views under the label of epistemic conservatism, the fact that one already believes something can make it rational to continue to believe it. A number of philosophers have found conservatism attractive, but traditional views are vulnerable to several powerful criticisms. In this paper, I develop an alternative to standard views by identifying a widespread assumption shared by conservatives and their critics - that rational norms govern states of mind like belief, and showing how rejecting this (...) assumption in favor of a process-oriented approach opens the door to a new, dynamic form of conservatism which preserves its core motivations while avoiding its traditional objections.

Evidentialism is the thesis that all reasons to believe p are evidence for p. Pragmatists hold that pragmatic considerations – incentives for believing – can also be reasons to believe. Nishi Shah, Thomas Kelly and others have argued for evidentialism on the grounds that incentives for belief fail a ‘reasoning constraint’ on reasons: roughly, reasons must be considerations we can reason from, but we cannot reason from incentives to belief. In the first half of the paper, I show that this (...) argument fails: the claim that we cannot reason from incentives is either false or does not combine with the reasoning constraint to support evidentialism. However, the failure of this argument suggests an alternative route to evidentialism. Roughly, reasons must be premises of good reasoning, but it is not good reasoning to reason from incentives to belief. The second half of the paper develops and defends this argument for evidentialism. (shrink)

ABSTRACT: Most of what we believe comes to us from the word of others, but we do not always believe what we are told. We often reject thinkers' reports by attributing biases to them. We may call this debunking. In this essay, I consider how debunking might work and then examine whether, and how often, it can help to preserve rational belief in the face of disagreement.

A survey of contemporary philosophical and scientific literatures reveals that different authors employ the term ‘heuristic’ in ways that deviate from, and are sometimes inconsistent with, one another. Given its widespread use in philosophy and cognitive science generally, it is striking that there appears to be little concern for a clear account of what phenomena heuristics pick out or refer to. In response, I consider several accounts of ‘heuristic’, and I draw a number of distinctions between different sorts of heuristics (...) in order to make sense of various research programmes. I then develop a working characterization of ‘heuristic’ which is shown to be coherent and robust enough to serve as a kind within philosophy and cognitive science broadly. My intent is not to pursue a unified account of ‘heuristic’, but to highlight some features of certain kinds of heuristics that are important for theorizing about cognition in order to proceed with a science of the mind/brain. 1 Why We Need an Appropriate Characterization of ‘Heuristic’2 Inadequate Definitions2.1 A positive attempt2.2 Heuristics versus guaranteed correct outcomes3 A Taxonomy of Heuristics3.1 Stimulus-driven versus heuristic3.2 Perceptual versus cognitive heuristics3.3 Computational versus cognitive heuristics3.4 Methodological versus inferential heuristics3.5 Summary of distinctions4 Characterizing Cognitive Heuristics4.1 Heuristics as rules of thumb4.2 Beyond rules of thumb: exploiting information5 Concluding Remarks.

We have noticed a pattern of arguments that exhibit a type of irrationality or a particular informal logical fallacy that is not fully captured by any existing fallacy. This fallacy can be explored through three examples where one misattributes a cause by focusing on a smaller portion of a larger set—specifically, the last or least known—and claiming that that cause holds a unique priority over other contributing factors for the occurrence of an event. We propose to call this fallacy the (...) “last straw fallacy” and will argue why these examples actually warrant a new logical name. Finally, we will show how these cases point to a deeper insight about the contexts in which we typically invoke this type of reasoning and some significant harmful consequences of doing so. (shrink)

Recent work on conditional reasoning argues that denying the antecedent [DA] and affirming the consequent [AC] are defeasible but cogent patterns of argument, either because they are effective, rational, albeit heuristic applications of Bayesian probability, or because they are licensed by the principle of total evidence. Against this, we show that on any prevailing interpretation of indicative conditionals the premises of DA and AC arguments do not license their conclusions without additional assumptions. The cogency of DA and AC inferences rather (...) depends on contingent factors extrinsic to, and independent of, what is asserted by DA and AC arguments. arguments do not license their conclusions without additional assumptions.
