Reasoning

Centrando la mirada en Cristo, las enseñanzas de Benedicto XVI desarrollan la íntima conexión que existe entre las tres virtudes teologales y la Verdad Encarnada, el Hijo de Dios hecho hombre. En efecto, no nos es posible creer en Jesucristo, amarlo y esperar en Él, si no conocemos su verdadero rostro, que se revela al intelecto humano iluminado por la fe. Este hecho pone en evidencia que el hombre necesita su natural capacidad de conocer la verdad para poder descubrir el (...) rostro de Cristo. Si se disocia de la razón, la fe cristiana pierde credibilidad y se convierte en una opción existencial arbitraria, pues resulta imposible argumentar racionalmente sobre ella. Por otra parte, las relaciones sociales y políticas se deshumanizan si se expulsa de la vida pública a las razones de la fe, porque una cultura que cierra sus puertas a Dios deja también afuera al hombre. Podremos alejar estos peligros sólo si la razón y la fe se reencuentran de un modo nuevo. Sin embargo, antes tenemos que recuperar la fe en la razón, es decir, nuestra confianza en su capacidad de conocer la verdad en toda su amplitud. (shrink)

Savage famously contravened his own theory when first confronting the Allais Paradox, but then convinced himself that he had made an error. We examine the formal structure of Savage’s ‘error-correcting’ reasoning in the light of (i) behavioural economists’ claims to identify the latent preferences of individuals who violate conventional rationality requirements and (ii) Broome’s critique of arguments which presuppose that rationality requirements can be achieved through reasoning. We argue that Savage’s reasoning is not vulnerable to Broome’s critique, but does not (...) provide support for the view that behavioural scientists can identify and counteract errors in people’s choices or preferences.

Dual-process theories of the mind emphasize how reasoning is an interplay between intuitive and reflective thinking. This paper aims to understand how the two types of processing interact in the moral domain. According to a ‘default-interventionist’ model of moral reasoning intuition and reflection are conflicting cognitions: intuitive thinking would elicit heuristic and deontological responses, whereas reflection would favour utilitarian judgements. However, the evidence for the default interventionist view is inconclusive and challenged by a growing amount of counterevidence in recent years. (...) The recent empirical findings favour an interdependent rather than conflicting view of the two types of information processing in the moral domain. In this view, which I call dual-process reflective equilibrium, intuition and reflection cooperate in moral reasoning to reach a reflective goal, which is supposedly normative justification. In sum, on the one hand, the scope of moral intuitions extends to selecting relevant information and calling for reflection whenever a problem presents conflicting aspects; on the other hand, the purpose of moral reflection is to rationalize pre-reflective intuitions to provide articulated and accessible reasons.

Inferences from the absence of evidence to something are common in ordinary speech, but when used in scientific argumentations are usually considered deficient or outright false. Yet, as demonstrated here with the help of various examples, archaeologists frequently use inferences and reasoning from absence, often allowing it a status on par with inferences from tangible evidence. This discrepancy has not been examined so far. The article analyses it drawing on philosophical discussions concerning the validity of inference from absence, using probabilistic (...) models that were originally developed to show that such inferences are weak and inconclusive. The analysis reveals that inference from absence can indeed be justified in many important situations of archaeological research, such as excavations carried out to explore the past existence and time-span of sedentary human habitation. The justification is closely related to the fact that archaeology explores the human past via its material remains. The same analysis points to instances where inference from absence can have comparable validity in other historical sciences, and to research questions in which archaeological inference from absence will be problematic or totally unwarranted.

This paper traces the borders between presupposing, believing, and having faith. These three attitudes are often equated and confused in the contemporary image of the historically and culturally situated character of rationality. This confusion is problematic because, on the one hand, it prevents us from fully appreciating the way in which this image of rationality points towards a dissolving of the opposition between faith and reason; on the other hand, it leads to forms of fideism. After bringing this differentiation into (...) sharper focus, a concept of faith in turn will come into view which challenges contemporary forms of fideism, to the extent that it embraces the possibility of examining and evaluating our systems of beliefs and basic presuppositions. This examination has nothing to do with justification or verification but rather with a sort of confrontation and discernment of the trust we have in what we take for granted. (shrink)

The paper argues for a version of the Guise of the Good thesis, namely the claim that if someone acts as the result of practical reasoning, then she takes her premises to jointly provide a sufficient and undefeated reason for her action. I argue for this by showing, first, that it is an application of Boghossian's Taking Condition on inference to practical reasoning and, second, that the motivations for the Taking Condition for theoretical reasoning carry over to practical reasoning. I (...) end by arguing that this version of the Guise of the Good withstands standard objections. (shrink)

This paper shows that our popular account of weakness of will is inconsistent with dilemmas. In dilemmas, agents judge that they ought to do one thing, that they ought to do something else, and that they cannot do both. They must act against either of their two judgments. But such action is commonly understood as weakness of will. An agent is weak-willed in doing something if she judges that she ought to and could do something else instead. Thus, it seems (...) that, in a dilemma, the agent is weak-willed by definition. But this is puzzling: clearly, the two are different phenomena. The puzzle may support scepticism about weakness of will or dilemmas. Here, I argue that the two are consistent on a revised understanding of weakness of will. To do so, I further distinguish the mental states of an agent in a dilemma from those of a weak-willed person. (shrink)

Half a century later, a Dretskean stance on epistemic closure remains a minority view. Why? Mainly because critics have successfully poked holes in the epistemologies on which closure fails. However, none of the familiar pro-closure moves works against the counterexamples on display here. It is argued that these counterexamples pose the following dilemma: either accept that epistemic closure principles are false, and steal the thunder from those who attack classical logic on the basis of similarly problematic cases—specifically, relevance logicians and (...) like-minded philosophers—or stick with closure and surrender to relevantist claims of failure in truth-preservation aimed at classical rules of inference. Classicist closure advocates find the promise of a way out of the dilemma in the works of Roy Sorensen and John Hawthorne. The paper argues against their pro-closure move and renews Robert Audi’s call for a theory of closure-failure. (shrink)

The superposition of magical thinking, quantum entanglement, and self-referential recursion explains the relationship between human and machine intelligence (universal intelligence).

The paper begins with a characterization of thought experiments, followed by a general outline of contemporary debates in the field. The discussion reveals that the most significant controversyinvolved is the dispute over the epistemic status of thought experiments between empiricists, Platonists, and the proponents of mental models. After a critical analysis of these approaches, a new theoretical framework proposed by Paul Bartha is introduced. It is suggested that Bartha’s approach, which appeals to a theory of analogy, offers new insights into (...) the structure of thought experiments. The paper concludes with general remarks on the state of the art in the field. (shrink)

Having a confirmation bias sometimes leads us to hold inaccurate beliefs. So, the puzzle goes: why do we have it? According to the influential argumentative theory of reasoning, confirmation bias emerges because the primary function of reason is not to form accurate beliefs, but to convince others that we’re right. A crucial prediction of the theory, then, is that confirmation bias should be found only in the reasoning domain. In this article, we argue that there is evidence that confirmation bias (...) does exist outside the reasoning domain. This undermines the main evidential basis for the argumentative theory of reasoning. In presenting the relevant evidence, we explore why having such confirmation bias may not be maladaptive.

What is human reason, how did it arise, how is it connected to animal reason? In The Enigma of Reason (ER) Hugo Mercier and Dan Sperber (2017) suggest that reason evolved driven by the need to support communication and coordination in small human groups. They contrast this to the idea that the function of reason is to enable humans to make better decisions and develop more accurate beliefs. After a summation of the ER argument, the theory is critiqued and two (...) of their assumptions -- that human cognition is based on massive modularity and that reason co-evolved with and is dependent upon language -- are challenged. Alternatives to these assumptions are presented from the perspective of pattern matching processes in neural dynamical systems, which it is asserted provides a more realistic approach to the functioning of the brain and mind.

It is often suggested that when opinions differ among individuals in a group, the opinions should be aggregated to form a compromise. This paper compares two approaches to aggregating opinions, linear pooling and what I call opinion agglomeration. In evaluating both strategies, I propose a pragmatic criterion, No Regrets, entailing that an aggregation strategy should prevent groups from buying and selling bets on events at prices regretted by their members. I show that only opinion agglomeration is able to satisfy the (...) demand. I then proceed to give normative and empirical arguments in support of the pragmatic criterion for opinion aggregation, and that ultimately favor opinion agglomeration. (shrink)

Charles Peirce’s Illustrations of the Logic of Science is an early work in the philosophy of science and the official birthplace of pragmatism. It contains Peirce’s two most influential papers: “The Fixation of Belief” and “How to Make Our Ideas Clear,” as well as discussions on the theory of probability, the ground of induction, the relation between science and religion, and the logic of abduction. Unsatisfied with the result and driven by a constant, almost feverish urge to improve his work, (...) Peirce spent considerable time and effort revising these papers. After the turn of the century these efforts gained significant momentum when Peirce sought to establish his role in the development of pragmatism while distancing himself from the more popular versions that had become current. The present edition brings together the original series as it appeared in Popular Science Monthly and a selection of Peirce’s later revisions, many of which remained hidden in the mass of messy manuscripts that were left behind after his death in 1914.

Which rules should guide our reasoning? Human reasoners often use reasoning shortcuts, called heuristics, which function well in some contexts but lack the universality of reasoning rules like deductive implication or inference to the best explanation. Does it follow that human reasoning is hopelessly irrational? I argue: no. Heuristic reasoning often represents human reasoners reaching a local rational maximum, reasoning more accurately than if they try to implement more “ideal” rules of reasoning. I argue this is a genuine rational achievement. (...) Our ideal rational advisors would advise us to reason with heuristic rules, not more complicated ideal rules. I argue we do not need a radical new account of epistemic norms to make sense of the success of heuristic reasoning. (shrink)

Suppositions can be introduced in either the indicative or subjunctive mood. The introduction of either type of supposition initiates judgments that may be either qualitative, binary judgments about whether a given proposition is acceptable or quantitative, numerical ones about how acceptable it is. As such, accounts of qualitative/quantitative judgment under indicative/subjunctive supposition have been developed in the literature. We explore these four different types of theories by systematically explicating the relationships canonical representatives of each. Our representative qualitative accounts of indicative (...) and subjunctive supposition are based on the belief change operations provided by AGM revision and KM update respectively; our representative quantitative ones are offered by conditionalization and imaging. This choice is motivated by the familiar approach of understanding supposition as `provisional belief revision' wherein one temporarily treats the supposition as true and forms judgments by making appropriate changes to their other opinions. To compare the numerical judgments recommended by the quantitative theories with the binary ones recommended by the qualitative accounts, we rely on a suitably adapted version of the Lockean thesis. Ultimately, we establish a number of new results that we interpret as vindicating the often-repeated claim that conditionalization is a probabilistic version of revision, while imaging is a probabilistic version of update.

Choice-theoretic and philosophical accounts of rationality and reasoning address a multi-attitude psychology, including beliefs, desires, intentions, etc. By contrast, logicians traditionally focus on beliefs only. Yet there is 'logic' in multiple attitudes. We propose a generalization of the three standard logical requirements on beliefs -- consistency, completeness, and deductive closedness -- towards multiple attitudes. How do these three logical requirements relate to rational requirements, e.g., of transitive preferences or non-akratic intentions? We establish a systematic correspondence: each logical requirement (consistency, completeness, (...) or closedness) is equivalent to a class of rational requirements. Loosely speaking, this correspondence connects the logical and rational approaches to psychology. Addressing John Broome's central question, we characterize the extent to which reasoning can help achieve consistent, complete, or closed attitudes, respectively. (shrink)

This book review, published in Kant Studien 108.3 (Sept. 2017), pp.467-471, summarizes and assesses Lawrence R. Pasternack's book, Routledge Philosophy Guidebook to Kant on Religion within the Boundaries of Mere Reason: An Interpretation and Defense (London and New York: Routledge, 2014).

In this article, I focus on the circular relationship that, in his 1998 encyclical, Jean Paul II argued there is between faith and reason. I first note that this image of circularity needs some explaining, because it is not clear where exactly the circular process begins and ends. I then argue that an explanation can be found in Aquinas’s reflection on the gift of understanding. Aquinas referred to the virtue of faith as caused by God, which promotes human reason, and (...) this in turn strengthens the certainty of faith. (shrink)

Robert Brandom's "The Pragmatist Enlightenment" describes the advent of American pragmatism as signaling a sea-change in our understanding of human reason away from the top-down Euclidian models of reasoning, warrant and knowledge inspired by the physical sciences, toward the far more bottom-up, narrative, inherently fallible and dialogical forms of reasoning of the life and human sciences. It is against this backdrop that Talmudic Judaism emerges not only as an early anticipation of the pragmatist enlightenment, but as going a substantial and (...) radical step beyond it, that in the context of religious commitment and reasoning, is unprecedented.

The term ‘intelligence’ as used in this paper refers to items of knowledge collected for the sake of assessing and maintaining national security. The intelligence community (IC) of the United States (US) is a community of organizations that collaborate in collecting and processing intelligence for the US. The IC relies on human-machine-based analytic strategies that 1) access and integrate vast amounts of information from disparate sources, 2) continuously process this information, so that, 3) a maximally comprehensive understanding of world actors (...) and their behaviors can be developed and updated. Herein we describe an approach to utilizing outcomes-based learning (OBL) to support these efforts that is based on an ontology of the cognitive processes performed by intelligence analysts. Of particular importance to the Cognitive Process Ontology is the class Representation that is Warranted. Such a representation is descriptive in nature and deserving of trust in its veridicality. The latter is because a Representation that is Warranted is always produced by a process that was vetted (or successfully designed) to reliably produce veridical representations. As such, Representations that are Warranted are what in other contexts we might refer to as ‘items of knowledge’. (shrink)

Um die Presse- und Meinungsfreiheit wird Tag für Tag gerungen - auch in Deutschland, wo sie im Grundgesetz verankert ist. Was darf man sagen? Wie weit geht die Meinungsfreiheit?

Rechtsextremisten inszenieren sich als Opfer einer vermeintlichen Meinungsdiktatur, Hasskommentare zerstören die Streitkultur und provozieren neue Gesetze, die (...) im schlechtesten Fall ihrerseits die Meinungsfreiheit aushöhlen. Gut verständlich beschreiben Experten unterschiedlicher Disziplinen die Dimensionen und Herausforderungen der Meinungsfreiheit.

Being questioned about the nature of Christian faith, Mark Twain famously declared it as 'believing what you know ain't so'. Indeed, the role of reason for faith is a matter of dispute. Jesus, some argue, was not a philosopher or a teacher of wisdom. Rather, he is the saviour because of his unassuming sacrificial death and resurrection. Not reason, but the leap of faith is the ultimate condition of salvation. The Enlightenment however epitomises a Copernican revolution in favour of reason. (...) According to Charles Taylor, the dissemination of Jesus' message into Hellenistic culture contains within itself the risk of a secularisation of the faith. At the same time, voices opposing the overemphasis of reason have also been raised throughout the ages. Paul's speech to the Athenians was one such occasion that deals with the ambiguous relationship between faith and reason. Relying purely on divine grace and the Bible alone, Martin Luther rejected any form of speculative theology. According to the Reformer, it is a type of theology that trusts more in human reason than in God's revelation. In Luther's opinion, it also reverses the moral order because theological speculation justifies evil as good while professing as good what is evil. To such a theology of human glory, Luther prefers a theology of the cross that 'calls the thing what it actually is'. For the former Augustinian monk only God's grace is good beyond reasonable doubt. Hence true theologians are lovers of the cross while theologians of glory misuse their reason for the worst. Luther's theology of the cross, Marco Barone claims, has its root in Augustine. Hence, Luther's Augustinism appears to have decidedly broken with Aristotelian scholasticism. In this context, Thomas Aquinas was criticised for his threefold failure. First, the Dominican friar's speculative theology lacks an experiential human dimension. Secondly, it gives too much credit to Aristotle. Thirdly, Thomas is reprimanded for his serious deficiency of a theology of justification. (shrink)

Richard Sorabji presents a unique discussion of the development of moral conscience over a period of 2500 years, from the playwrights of the fifth century BCE to the present. He addresses key topics including the original meaning and continuing nature of conscience, the ideas of freedom of religion and conscience with climaxes in the early Christian centuries and the seventeenth, the disputes on absolution or 'terrorisation' of conscience, dilemmas of conscience,and moral double-bind, the reliability of conscience if it is shaped (...) by local custom, and modern opposition to the idea of conscience and its role in legislation.

In this paper, I examine a kind of delusion in which the patients judge that their occurrent thoughts are false and try to abandon them precisely because they are false, but fail to do so. I call this delusion transparent, since it is transparent to the sufferer that their thought is false. In explaining this phenomenon, I defend a particular two-factor theory of delusion that takes the proper integration of relevant reasoning processes as vital for thought-evaluation. On this proposal, which (...) is a refinement of Gerrans’s account of delusion as unsupervised by decontextualized processing, I can have all my reasoning processes working reliably and thus judge that my delusion is false but, if I cannot use their outputs when revising the thought itself, the delusion will persist. I also sketch how this framework explains some interesting cases of failed belief-revision in the general population in which people judge that ~p but nonetheless continue to believe that p.

Enkratic reasoning – reasoning from believing that you ought to do something to an intention to do that thing – seems good. But there is a puzzle about how it could be. Good reasoning preserves correctness, other things equal. But enkratic reasoning does not preserve correctness. This is because what you ought to do depends on your epistemic position, but what it is correct to intend does not. In this paper, I motivate these claims and thus show that there is (...) a puzzle. I then argue that the best solution is to deny that correctness is always independent of your epistemic position. As I explain, a notable upshot is that a central epistemic norm directs us to believe, not simply what is true, but what we are in a position to know. (shrink)

The central idea of this paper is that Michel Foucault and Søren Kierkegaard are unexpected allies in the investigation into the relation between madness and reason. These thinkers criticize reason’s presumption of purity and call into question reason’s isolation from madness. Strategies of indirect communication and regard for paradox from Kierkegaard’s nineteenth-century works find new ground in Foucault’s twentieth-century archaeological undertaking as Foucault illuminates “both-and” moments in the history of madness, uncovering points where rationalism paradoxically conceives of madness or where (...) madness is not unreasonable. Furthermore, for both thinkers, form and content meet, as Kierkegaard and Foucault’s occasionally “delirious lyricism” exemplifies the intertwining of logical and illogical forces. (shrink)

In this paper, I will focus on a type of confabulation that emerges in relation to questions about mental attitudes whose causes we cannot introspectively access. I argue against two popular views that see confabulations as mainly offering a psychological story about ourselves. On these views, confabulations are the result of either a cause-tracking mechanism or a self-directed mindreading mechanism. In contrast, I propose the view that confabulations are mostly telling a normative story: they are arguments primarily offered to justify (...) one’s attitudes, and they are produced by our argumentative reasoning mechanism driven by the biological goal of presenting ourselves as good reasoners and as reliable sources of information.

John Broome has developed an account of rationality and reasoning which gives philosophical foundations for choice theory and the psychology of rational agents. We formalize his account into a model that differs from ordinary choice-theoretic models through focusing on psychology and the reasoning process. Within that model, we ask Broome’s central question of whether reasoning can make us more rational: whether it allows us to acquire transitive preferences, consistent beliefs, non-akratic intentions, and so on. We identify three structural types of (...) rationality requirements: consistency requirements, completeness requirements, and closedness requirements. Many standard rationality requirements fall under this typology. Based on three theorems, we argue that reasoning is successful in achieving closedness requirements, but not in achieving consistency or completeness requirements. We assess how far our negative results reveal gaps in Broome's theory, or deficiencies in choice theory and behavioral economics. (shrink)

Changing our minds isn't easy. Even when we recognize our views are disputed by intelligent and informed people, we rarely doubt our rightness. Why is this so? How can we become more open-minded, putting ourselves in a better position to tolerate conflict, advance collective inquiry, and learn from differing perspectives in a complex world? -/- Nathan Ballantyne defends the indispensable role of epistemology in tackling these issues. For early modern philosophers, the point of reflecting on inquiry was to understand how (...) our beliefs are often distorted by prejudice and self-interest, and to improve the foundations of human knowledge. Ballantyne seeks to recover and modernize this classical tradition by vigorously defending an interdisciplinary approach to epistemology, blending philosophical theorizing with insights from the social and cognitive sciences. -/- Many of us need tools to help us think more circumspectly about our controversial views. Ballantyne develops a method for distinguishing between our reasonable and unreasonable opinions, in light of evidence about bias, information overload, and rival experts. This method guides us to greater intellectual openness--in the spirit of skeptics from Socrates to Montaigne to Bertrand Russell--making us more inclined to admit that sometimes we don't have the right answers. With vibrant prose and fascinating examples from science and history, Ballantyne shows how epistemology can help us know our limits. (shrink)

In this paper we present an approach to conditional reasoning tasks based on two main ideas. The first idea is that, in contrast with what is usually assumed, an ‘if… then…’ sentence is not an adequate translation in natural language of a logical formula containing a material implication as its principal operator. The second idea is that when subjects are required to check the validity of a sentence in a task, their inferences are not driven uniquely by the content of (...) the sentence, but also by other information embedded in the task scenario and, eventually, by their knowledge about the topic (i.e. information stored in memory). Data from 30 subjects tested on six different tasks are reported as evidence for our approach. The results show that conditional tasks are significantly more complex only when they are presented with ‘if… then…’ sentences and when the subject cannot rely on any extra information, such as contextual information or knowledge about the topic.

Søren Kierkegaard (1813-1855) has often been cast as an irrationalist -- an enemy of reason, logic, and perhaps even truth. It is easy to see why. Some of his works encourage us to "crucify" our understanding or to take a leap of faith beyond the evidence.[1] We also encounter texts suggesting that passionate beliefs are more important than true ones.[2] Perhaps his most frequently read book, Fear and Trembling, lauds Abraham for following God's commands "by virtue of the absurd."[3] Finally, (...) a number of passages encourage us to accept "the absolute paradox" or "the contradiction" of the God-man, Jesus Christ.[4] -/- Richard McCombs joins a growing chorus of scholars who reject this view. Indeed, there is something approaching a consensus among specialists that Kierkegaard is not as irrational as he appears. What sets McCombs apart is that he also defends a more ambitious thesis. In addition to downplaying the irrationality of Kierkegaard, he maintains that Kierkegaard is actually a "robustly rational thinker" (7). (shrink)

Dogmatism is the view that perceptual experience provides immediate defeasible justification for certain beliefs. The bootstrapping problem for dogmatism is that it sanctions a certain defective form of reasoning that concludes in the belief that one's perceptual faculties are reliable. This paper argues that the only way for the dogmatist to avoid the bootstrapping problem is to claim that epistemic justification fails to have a structural property known as cut. This allows the dogmatist to admit that each step in the (...) defective reasoning considered on its own is acceptable, but when stitched together, these pieces of reasoning are unacceptable (§2). The fact that this is the only plausible solution to the bootstrapping problem is, in one way, bad news. This is because it adds another member to a family of recently uncovered results that show dogmatism is incompatible with certain connections between epistemic justification and probabilities (§3). But I try to make the best of it on the dogmatist’s behalf. I show that within a certain kind of foundationalist framework, we can make good on this idea that epistemic justification fails to satisfy cut in a way needed to solve the bootstrapping problem (§4–5).

La superación del racionalismo y del relativismo no ha podido gestarse con fecundidad. Posiblemente porque el absolutismo racionalista -que salva la razón a costa de anular la vida- y el relativismo -que salva la vida negando la razón- se han desplazado en una dimensión única que imposibilitaba la insumisión a ese dilema vertebrado por una concepción absolutista de la verdad y que nos constriñe a instalarnos en alguno de sus términos. La constante aparición del nexo entre los problemas antropológicos más (...) relevantes y la crítica de la metafísica exigen que la postmodernidad sea reubicada en un contexto que supere su inserción en un escenario que tengan por trasfondo únicamente a la modernidad. En otras palabras, hay una necesidad de trascender el binomio modernidad-postmodernidad. De esta manera, se considera que la tradición realista debe aparecer en escena en abierto diálogo crítico con los posicionamientos cronológicamente posteriores. Por lo que se refiere a la estructura de la presente obra hay que decir que sus once capítulos se distribuyen en tres partes. La primera de ellas intenta desentrañar y ordenar los elementos que generan el estado de cierta postración en el que se halla el pensamiento crítico-especulativo. En la segunda parte se procede a recorrer cada una de las derivaciones más relevantes de la desconfianza de la razón hacia sí misma. Por último, la tercera parte intenta poner de manifiesto qué posibilidades quedan al pensamiento de la constitución de lo nuevo tanto en el ámbito filosófico como en el pedagógico. Los modernos creyeron que al ser humano cabe forjarlo por el poder de la razón; los postmodernos estiman que no debe hacerse. ¿Es sólo por casualidad que hay una coincidencia fundamental entre ambas perspectivas? En el fondo, uno y otro convienen que la razón lo puede todo; modernos y postmodernos coinciden en la creencia del poder ilimitado de la razón y, como consecuencia de ello, creen en la posibilidad de la ilimitada y absoluta transformación de la totalidad de lo real. Y ello, aunque lo hagan en sentido diverso y lo valoren de manera inversa. Cabe, pues, pensar que, en el fondo, no hay más que una remodelación monótona de lo mismo. Las repercusiones del nihilismo, del relativismo moral, de la crisis antropológica postmoderna, de los nacionalismos identitarios, del pluralismo religioso, de la política democrática y de los tópicos del relativismo cultural son, pues, abordados –y enhebrados- en la Crítica de la razón moderna. Por ello, esta obra supone una seria y muy completa contribución al esclarecimiento de la vertebración del pensamiento y las prácticas culturales vigentes. Además, es una obra imprescindible en la biblioteca de profesores y de estudiantes de las facultades de Educación, Filosofía, Historia, Teología, Ciencias Políticas y Sociología. Y también resulta relevante para todas aquellas personas que se afanan por comprender los fundamentos teóricos de las perspectivas sociales y humanísticas actuales así como sus derivaciones y praxis concretas.

There is consensus among computer scientists, logicians, and philosophers that good reasoning with qualitative beliefs must have the structural property of cumulative transitivity or, for short, cut. This consensus is typically explicitly argued for partially on the basis of practical and mathematical considerations. But the consensus is also implicit in the approach philosophers take to almost every puzzle about reasoning that involves multiple steps: philosophers typically assume that if each step in reasoning is acceptable considered on its own, the whole (...) chain of reasoning must also acceptable. In this paper I focus on whether there are good philosophical reasons for thinking that the consensus that good reasoning must satisfy cut is true. My central claim is that we should not accept the consensus—good reasoning might not satisfy cut. In particular, I consider four arguments for the consensus and explain why they are unpersuasive. (§2-5). I then show that the issue of whether good reasoning is cut turns on a substantive yet until now unnoticed question in epistemology (§6). (shrink)

One of the important problems that have to be dealt with in the Philosophy of Science is to account for the high reliability of a very large part of our inductive inferences. This reliability is noteworthy because not only were many of these inferences made by ordinary people, even by children, but they were very often based on the observation of just a few positive instances. In the present paper, I deal with this problem by treating it as a normal (...) empirical problem. This approach enables us to make an important step towards an explanation of the phenomenon and, consequently, towards the formulation of a general theory of scientific inquiry. (shrink)

In this paper I argue that defeasible inferences are occasion-sensitive: the inferential connections of a given claim depend on features of the circumstances surrounding the occasion of inference. More specifically, it is an occasion-sensitive matter which possible defeaters have to be considered explicitly by the premises of an inference and which possible defeaters may remain unconsidered, without making the inference enthymematic. As a result, a largely unexplored form of occasion-sensitivity arises in inferentialist theories of content that appeal to defeasible inferences.

If the cultural variations concerning knowledge and research on ordinary reasoning are part of cultural history, what kind of historiographical method is needed in order to present the history of its evolution? This paper proposes to introduce the study of theories of reasoning into a historiographic perspective because we assume that the answer to the previous question does not only depend of internal controversies about how reasoning performance is explained by current theories of reasoning.

This paper examines precursors and consequents of perceived relevance of a proposition A for a proposition C. In Experiment 1, we test Spohn's assumption that ∆P = P − P is a good predictor of ratings of perceived relevance and reason relations, and we examine whether it is a better predictor than the difference measure − P). In Experiment 2, we examine the effects of relevance on probabilistic coherence in Cruz, Baratgin, Oaksford, and Over's uncertain “and-to-if” inferences. The results suggest (...) that ∆P predicts perceived relevance and reason relations better than the difference measure and that participants are either less probabilistically coherent in “and-to-if” inferences than initially assumed or that they do not follow P = P. Results are discussed in light of recent results suggesting that the Equation may not hold under conditions of irrelevance or negative relevance. (shrink)
