Are philosophy and literature allies or enemies in Jorge Luis Borges's fictions? In this paper, I argue that Borges can satisfy membership in the allies camp because his fictions provide the imaginative scenarios the allies believe are so necessary to this coalition; however, because his stories question philosophy's hold on reality, they can also seem to fall into the enemies camp by countervailing any claim philosophy has on reality and truth; although, ultimately, the manner in which Borges forges an (...) alliance between philosophy and literature will be for reasons not traditionally accepted by those in either the allies or enemies camps.

Ontologies are some of the most central constructs in today's large plethora of knowledge technologies, namely in the context of the semantic web. As their coinage indicates, they are direct heirs to the ontological investigations in the long Western philosophical tradition, but it is not easy to make bridges between them. Contemporary ontological commitments often take causality as a central aspect for the ur-segregation of entities, especially in scientific upper ontologies; theories of causality and philosophical ontological investigations often go hand-in-hand, (...) and were essentially inseparable in medieval thought. This constitutes the foundation for a bridge, and this article analyzes the causality-based ontology of the late medieval philosopher Dietrich of Freiberg from the viewpoint of today's upper-ontology engineering. In this bridging attempt, it offers a translation into English of the first part of Dietrich's De origine (abbreviated title) that is a compromise between traditional scholarly translations of medieval Latin philosophical texts and contemporary ontology.

Foundational ontologies, central constructs in ontological investigations and engineering alike, are based on ontological categories. Firstly proposed by Aristotle as the very ur- elements from which the whole of reality can be derived, they are not easy to identify, let alone partition and/or hierarchize; in particular, the question of their number poses serious challenges. The late medieval philosopher Dietrich of Freiberg wrote around 1286 a tutorial that can help us today with this exceedingly difficult task. In this paper, I discuss (...) ontological categories and their importance for foundational ontologies from both the contemporary perspective and the original Aristotelian viewpoint, I provide the translation from the Latin into English of Dietrich's De origine II with an introductory elaboration, and I extract a foundational ontology–that is in fact a single-category one–from this text rooted in Dietrich's specification of types of subjecthood and his conception of intentionality as causal operation.

In this paper I present reasons for us to accept the hypothesis that suspended judgment has correctness conditions, just like beliefs do. Roughly put, the idea is that suspended judgment about p is correct when both p and ¬p might be true in view of certain facts that characterize the subject’s situation. The reasons to accept that hypothesis are broadly theoretical ones: it adds unifying power to our epistemological theories, it delivers good and conservative consequences, and it allows us to (...) assess processes of reasoning involving attitudes of suspended judgment.

Introduction to the Inaugural Issue of the Erasmus Journal for Philosophy and Economics.

Paul Silva has recently argued that doxastic justification does not have a basing requirement. An important part of his argument depends on the assumption that doxastic and moral permissibility have a parallel structure. I here reply to Silva's argument by challenging this assumption. I claim that moral permissibility is an agential notion, while doxastic permissibility is not. I then briefly explore the nature of these notions and briefly consider their implications for praise and blame.

For millennia, knowledge has eluded a precise definition. The industrialization of knowledge (IoK) and the associated proliferation of the so-called knowledge communities in the last few decades caused this state of affairs to deteriorate, namely by creating a trio composed of data, knowledge, and information (DIK) that is not unlike the aporia of the trinity in philosophy. This calls for a general theory of knowledge (ToK) that can work as a foundation for a science of knowledge (SoK) and additionally distinguishes (...) knowledge from both data and information. In this paper, I attempt to sketch this generality via the establishing of both knowledge structures and knowledge systems that can then be adopted/adapted by the diverse communities for the respective knowledge technologies and practices. This is achieved by means of a formal–indeed, mathematical–approach to epistemological matters a.k.a. formal epistemology. The corresponding application focus is on knowledge systems implementable as computer programs. (shrink)

SINGULARIDAD: 12 Preceptos para la Vida Trascendental | © 2023 Cromwell Black Publishing House | Obra original por Luis Herrera. -/- Vivir trascendentalmente no es lo mismo que 'tener las respuestas a la vida.' La intención con la que se ha escrito este libro es ayudarte a identificar a Dios dentro de ti. La religión es una señal, pero no es la respuesta. La filosofía es una señal, pero no es la respuesta. Las personas que se identifican en exceso (...) con un grupo o tribu por razones ideológicas, inevitablemente se encuentran con la decepción porque siempre habrá algunos principios con los que internamente se opongan y estén en desacuerdo. Aun así, ignoran su voz interior para 'encajar con los demás.' El hombre es un animal social y la excomunión de la tribu ha sido equivalente a la extinción de nuestra línea desde nuestros días como cazadores y recolectores. Al vivir trascendentalmente, he aprendido a reconocer, acoger y aceptar el espacio entre mí y mi tribu. Te invito a hacer lo mismo. -/- Aprendiendo a escuchar al Dios que está dentro, puedo confiar más en mi voz interior porque hay un mensaje hablado allí, único para mí, que nunca será impreso en las páginas de la Biblia, el Corán, el Tao Te Ching o cualquier otro libro. Solo hay un TÚ. Otros pueden tener tu nombre, pero no tu identidad. Pueden compartir tu fecha de nacimiento y hospital, pero no tus padres. Pueden compartir tus padres, pero no tu nombre. ¿Ves a lo que me refiero aquí? Por lo tanto, ¿cómo puede una religión, educación o filosofía 'talla única' responder a la pregunta sobre el significado de la vida? No hay un significado de la vida, porque no hay una vida. Hay vidas infinitas, para las cuales deben proporcionarse significados infinitos. De ahí la importancia de aprender a confiar en ti mismo, tu voz interior, tu conciencia, el Dios que está dentro de ti. (shrink)

SINGULARITY: 12 Precepts for Transcendental Living | © 2022 Cromwell Black Publishing House | Original work by Luis Herrera. -/- Living transcendentally is not the same as ‘having the answers to life.’ The intention with which this book is written is to help you identify the God within yourself. Religion is a guidepost, but not the answer. Philosophy is a guidepost, not the answer. People that over-identify with one group or tribe for ideological reasons invariably meet with disappointment because (...) there will always be some tenets they internally oppose and disagree with. Yet they ignore their inner voice in order to ‘fit in with the rest.’ Man is a social animal and excommunication from the tribe has been tantamount to extinction of our lineage since our days as hunters and gatherers. By living transcendentally I have learned to acknowledge, welcome and accept the space between myself and my tribe. I invite you to do the same. -/- Learning to listen to the God within, I can trust my inner voice more because there is a message spoken there, uniquely for me, that will never be printed on the pages of the Bible, or the Koran, or the Tao Te Ching, or any other book for that matter. There’s only one YOU. Others may have your name, but not your identity. They may share your birth date and hospital, but not your parents. They may share your parents, but not your name. Do you see what I’m getting at here? Therefore how can a ‘one-size fits all’ religion, education or philosophy possibly answer the question to your meaning of life? There is no the meaning of life, because there is no the life. There are infinite lives, for which infinite meanings must be furnished. Hence the importance of learning to trust yourself, your inner voice, conscience – the God within. (shrink)

This book concerns the nature and the norms of inquiry. It tackles not only philosophical issues regarding what inquiry is, but also issues regarding how it should and should not be executed. Roughly put, inquiry is the activity of searching for the true answers to questions of our interest. But what is the difference between empirical and armchair inquiry? And what are the right and the wrong ways to inquire? Under what conditions should one start inquiring? Which questions are such (...) that one should not inquire into them? The book offers answers to these questions. It argues that competent armchair inquiry only makes explicit what was already implicit--the inquirer already had the answer to her question before inquiring into it, though this was not explicit to her. It also argues that we should avoid inquiring into questions whose answers are unknowable to us, in the instrumental sense of 'should', and that different modes of inquiry are called for, depending on which type of information is available to the subject. These answers are rigorously argued for, and they stem from a unified framework for modeling the activity of inquiry. (shrink)

The van Wijngaarden grammars are two-level grammars that present many interesting properties. In the present article I elaborate on six of these properties, to wit, (i) their being constituted by two grammars, (ii) their ability to generate (possibly infinitely many) strict languages and their own metalanguage, (iii) their context-sensitivity, (iv) their high descriptive power, (v) their productivity, or the ability to generate an infinite number of production rules, and (vi) their equivalence with the unrestricted, or Type-0, Chomsky grammars.

James Sterba has recently argued that the free will defense fails to explain the compossibility of a perfect God and the amount and degree of moral evil that we see. I think he is mistaken about this. I thus find myself in the awkward and unexpected position, as a non-theist myself, of defending the free will defense. In this paper, I will try to show that once we take care to focus on what the free will defense is trying to (...) accomplish, and by what means it tries to do so, we will see that Sterba’s criticism of it misses the mark.

Not focusing on the history of classical logic, this book provides discussions and quotes central passages on its origins and development, namely from a philosophical perspective. Not being a book in mathematical logic, it takes formal logic from an essentially mathematical perspective. Biased towards a computational approach, with SAT and VAL as its backbone, this is an introduction to logic that covers essential aspects of the three branches of logic, to wit, philosophical, mathematical, and computational.

In Who's Afraid of Idealism? the philosophical concept of idealism, the extent to which reality is mind-made, is examined in new light. Author Luis M. Augusto explores epistemological idealism, at the source of all other kinds of idealism, from the viewpoints of Immanuel Kant and Friedrich Nietzsche, two philosophers who spent a large part of their lives denigrating the very concept. Working from Kant and Nietzsche's viewpoints that idealism was a scandal to philosophy and the cause of nihilism, Augusto (...) evaluates these philosophers and their role in shaping epistemological idealism. Using textual evidence from their writings and their reactions to western philosophers such as Plato, Descartes, and Hegel, Who's Afraid of Idealism? argues that in fact Kant and Nietzsche were really idealists at heart. In accessible prose, this text puts forward a theory that goes against current scholarly opinion, and even Kant and Nietzsche's opinions of themselves. (shrink)

Throughout the present text, an account of the main contributions of Luis Villoro Toranzo will be made as a tribute to three years after his death.

A. Newell and H. A. Simon were two of the most influential scientists in the emerging field of artificial intelligence (AI) in the late 1950s through to the early 1990s. This paper reviews their crucial contribution to this field, namely to symbolic AI. This contribution was constituted mostly by their quest for the implementation of general intelligence and (commonsense) knowledge in artificial thinking or reasoning artifacts, a project they shared with many other scientists but that in their case was theoretically (...) based on the idiosyncratic notions of symbol systems and the representational abilities they give rise to, in particular with respect to knowledge. While focusing on the period 1956-1982, this review cites both earlier and later literature and it attempts to make visible their potential relevance to today's greatest unifying AI challenge, to wit, the design of wholly autonomous artificial agents (a.k.a. robots) that are not only rational and ethical, but also self-conscious.

La propuesta inmaterialista de Berkeley, elaborada definitivamente en sus Principles (1710), tiene como antecedente remoto los postulados del capadocio Gregorio de Nisa, quien en algunas de sus obras desarrolló argumentos, en relación con la materia, muy semejantes a los que planteó Berkeley casi catorce siglos después. El presente escrito tiene por objetivo mostrar que las concepciones de ambos pensadores tienen elementos en común, lo que permite sostener que el filósofo de Cesarea es un antecede lejano del inmaterialismo berkeleyano. // Berkeley's (...) immaterialism has as a remote antecedent in the postulates of the Cappadocian Gregory of Nyssa, who in some of his works developed arguments, concerning the matter, very similar to those that Berkeley presented almost fourteen centuries later. This paper aims to show that both philosophical conceptions have elements in common, which allows us to assert that the Cappadocian father is a distant precedent of Berkeley's immaterialism.

To most of us – believers and non-believers alike – the possibility of a perfect God co-existing with the kinds of evil that we see calls out for explanation. It is unsurprising, therefore, that the belief that God must have justifying reasons for allowing all the evil that we see has been a perennial feature of theistic thought. Recently, however, a growing number of authors have argued that the existence of a perfect God is compatible with the existence of gratuitous (...) evil. Given powerful, millenia-long sensibilities about power and love and justice, it isn’t hard to find that suggestion simply incredible. Nonetheless, in this paper I will argue that the most prominent theistic alternatives to what has seemed incredible to most of us throughout most of history are themselves patently unacceptable for the theist as well. On any of the most widely accepted accounts of how God could have justifying reasons for permitting some evils, God’s existence means that we have justifying reasons for perpetrating and allowing every evil that we see. That's hard to swallow too. If I’m right about all of this, then two competing outcomes seem to present themselves as a possible result. On the one hand, for the theist, the apparently outrageous suggestion that the existence of a perfect God is compatible with gratuitous evil no longer looks like it faces a formidable, hard-to-resist alternative. On the other hand, some like me might think that my arguments go no distance at all towards dispelling the incredibility of the gratuitous evil nouvelle vague. On this line, theism may seem now to be between the rock and the hard place: it seems hard to make sense of the existence of a perfect God whether or not He has justifying reasons for allowing all the evil that we see.

Given plausible assumptions about the nature of evidence and undercutting defeat, many believe that the force of the evidential problem of evil depends on sceptical theism’s being false: if evil is...

Genera, typically hand-in-hand with their branching species, are essential elements of vocabulary-based information constructs, in particular scientific taxonomies. Should they also feature in formal ontologies, the highest of such constructs? I argue in this article that the answer is “Yes” and that the question posed in its title also has a Yes-answer: The way medieval ontologists sliced up the world into genera does matter to formal ontology. More specifically, the way Dietrich of Freiberg, a Latin scholastic, conceived and applied strictly (...) generic criteria to slice up the world into its entities can provide some guidelines to the field of formal ontology with respect to not only its contents, but also its scope. In particular, Dietrich's information criterion plays here a central role. (shrink)

A short story about love, suspense and criminal inclinations. Un relato literario sobre amor y proyecciones criminales.

2nd edition. Many-valued logics are those logics that have more than the two classical truth values, to wit, true and false; in fact, they can have from three to infinitely many truth values. This property, together with truth-functionality, provides a powerful formalism to reason in settings where classical logic—as well as other non-classical logics—is of no avail. Indeed, originally motivated by philosophical concerns, these logics soon proved relevant for a plethora of applications ranging from switching theory to cognitive modeling, and (...) they are today in more demand than ever, due to the realization that inconsistency and vagueness in knowledge bases and information processes are not only inevitable and acceptable, but also perhaps welcome. The main modern applications of (any) logic are to be found in the digital computer, and we thus require the practical knowledge how to computerize—which also means automate—decisions (i.e. reasoning) in many-valued logics. This, in turn, necessitates a mathematical foundation for these logics. This book provides both these mathematical foundation and practical knowledge in a rigorous, yet accessible, text, while at the same time situating these logics in the context of the satisfiability problem (SAT) and automated deduction. The main text is complemented with a large selection of exercises, a plus for the reader wishing to not only learn about, but also do something with, many-valued logics. (shrink)

My starting point is what I call the Normative Authority Conception of justification, where S is justified in their belief that p at t (to some degree n) if and only if their believing that p at t is not ruled out by epistemic norms that have normative authority over S at t. With this in mind, this paper develops an account of doxastic justification by first developing an account of the normative authority of epistemic norms. Drawing from work in (...) political philosophy, I argue that (a) the cognitive and evaluative commitments and concerns behind our actual practices of holding each other and ourselves accountable for our beliefs reveal which epistemic norms we have consented to be under, and that (b) it is because we have consented to be under the authority of these norms – by actually holding ourselves and others accountable to them – that they in turn have normative authority over us. By connecting the authority of epistemic norms to the authority we have over ourselves in this way, the resulting account of doxastic justification (i) explains why it can be appropriate to criticize, resent, or sanction someone for having unjustified beliefs, (ii) avoids the phenomena of normative alienation and normative parochialism, and (iii) respects the social and collective nature of epistemic justification. (shrink)

What I call the Doxastic Puzzle, is the impression that while each of these claims seems true, at least one of them must be false: (a) Claims of the form ‘S ought to have doxastic attitude D towards p at t’ are sometimes true at t, (b) If Φ-ing at t is not within S’s effective control at t, then it is false, at t, that ‘S ought to Φ at t’, (c) For all S, p, and t, having doxastic (...) attitude D towards p at t is not within S’s effective control at t. All three natural replies to the puzzle have been pursued. Some have claimed that doxastic attitudes like believing that p are, in fact, within our effective control, or sufficiently so. Others have claimed that doxastic ought-claims, strictly speaking, are always false. And some have denied that effective control is required for the adequacy of doxastic ought-claims in general. I here pursue and examine a different strategy. In the first part of this paper, I argue that these claims are not only each true but actually not in tension with each other in the first place. Instead of attempting to dispel the puzzle, this solution proposes to evade it instead: to solve it by properly understanding, and by thereby accepting without contradiction, all of its constitutive claims. In the second part of the paper, I argue that the evasive strategy forces us to re-think our understanding of the place of normative reasons in epistemology. More exactly, it seems to come at the cost of one central way of thinking about our reasons for having doxastic attitudes, one where such reasons are good-standing exemplars of normative reasons in general. The evasive strategy, that is, threatens to lead us very quickly to a deflationary picture of epistemic normativity: it rescues normative talk, but sacrifices normative substance. I conclude by explaining why I think this is more consequential than some have made it out to be, and by suggesting that these consequences are welcome nonetheless. (shrink)

An analysis of--yet another--case of academic failure in multi- and interdisciplinarity. An editorial of the Journal of Knowledge Structures & Systems.

W.K. Clifford’s famous 1876 essay The Ethics of Belief contains one of the most memorable lines in the history of philosophy: "it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence." The challenge to religious belief stemming from this moralized version of evidentialism is still widely discussed today.

Ever since John Locke, philosophers have discussed the possibility of a normative epistemology: are there epistemic obligations binding the cognitive economy of belief and disbelief? Locke's influential answer was evidentialist: we have an epistemic obligation to believe in accordance with our evidence. In this dissertation, I place the contemporary literature on agency and reasons at the service of some such normative epistemology. I discuss the semantics of obligations, the connection between obligations and reasons to believe, the implausibility of Lockean evidentialism, (...) and some of the alleged connections between agency and justification.

Knowledge representation (KR) is actually more than representation: It involves also inference, namely inference of “new” knowledge, i.e. new facts. Logic programming is a suitable KR medium, but more often than not discussions on this programming paradigm focus on aspects other than KR. In this paper, I elaborate on the general theory of logic programming and give the essentials of two of its main implementations, to wit, Prolog and Datalog, from the viewpoint of deductive computing over knowledge bases, which includes (...) deductive programming.

There are many ways in which a speaker can confuse their audience. In this paper, I will focus on one such way, namely, a way of talking that seems to manifest a cross-level kind of cognitive dissonance on the part of the speaker. The goal of the paper is to explain why such ways of talking sound so twisted. The explanation is two-pronged, since their twisted nature may come either from the very mental states that the speaker thereby makes manifest, (...) or from how the speaker chooses to express themselves (even if there is nothing wrong with their mental states). So-called ‘Moore-paradoxical’ utterances are but one example of the phenomenon, and the explanation of what is wrong about them is subsumed under a more general explanation here—one that captures also the twisted-ness of utterances whereby questions are raised or intentions expressed.

Epistemologists often describe subjects as being capable of adopting a third kind of categorical doxastic stance regarding whether something is the case, besides belief and disbelief. They deploy a variety of idioms in order to ascribe that stance. In this paper, I flesh out the properties that the third kind of categorical stance is supposed to have and start searching for the best ways to ascribe it. The idioms ‘suspends judgment about whether’ and ‘is agnostic about whether’, among others, are (...) found to be unfit to play the desired role. In the end, I suggest that ‘is in doubt as to whether’ is our best choice among the alternatives surveyed here. (shrink)

In the following pages, the main proposal is to indicate how Max Weber has dialogued directly with some prerogatives from Kant’s Critic of practical Reason, following the reception of Wilhelm Windelband’s concept of “responsibility” (Verantwortlichkeit) and his theory of values. In sight of these influences, in this paper will be argued how Weber adherence to the neo-Kantian value concept has made possible a review on the categorical imperatives, which has turned his reading from Kantian philosophy to the proposal of an (...) antinomy between the ethic of conviction and the ethic of responsibility inside the Kantian moral maxims. -/- Nessa abordagem será proposto que a recepção de Max Weber do conceito de “responsabilidade” (Verantwortlichkeit) de Wilhelm Windelband, bem como sua revisão de certos elementos da filosofia dos valores neokantiana do sudoeste da Alemanha, permitiram que Weber estabelecesse um diálogo mais direto com os pressupostos de Kant em sua Crítica da razão prática. Em vista dessas influências, o presente artigo argumentará que a maneira como Weber revisa os imperativos categóricos direcionou sua compreensão da filosofia kantiana pelo conceito de “valores”, o permitindo ainda, propor a existência de uma antinomia entre a ética da convicção e da responsabilidade no interior das máximas morais kantianas.

"Noah and the Olive Branch" by Luis Herrera explores the profound symbolism of the olive branch in the context of human morality and existential renewal. Drawing on the biblical narrative of Noah's Ark, Herrera delves into a metaphor for peace, reconciliation, and the restoration of harmony between humanity and the natural world. The work interprets the olive branch not merely as a sign of the flood's end, but as a deeper emblem of ethical rebirth, signifying the opportunity for humanity (...) to reconstruct a more just and compassionate world after calamity. -/- Through a philosophical lens, Herrera examines the duality of destruction and creation, positing that potential for moral and spiritual growth follows great trials. The text questions the nature of divine justice and human responsibility, suggesting a call for ongoing ethical vigilance in a world perpetually on the brink of self-destruction. -/- It is a parable for man's quest for connection and reconciliation with the divine, in a violent world filled with chaos, anarchy and the antinomian pursuit of hedonistic ideals. Herrera's work resonates with contemporary concerns about cultural degradation and social fragmentation, urging a re-evaluation of our relationship with God and each other. The olive branch, in this interpretation, becomes a timeless symbol of hope, resilience, and the enduring quest for a harmonious existence. (shrink)

Logic arguably plays a role in the normativity of reasoning. In particular, there are plausible norms of belief/disbelief whose antecedents are constituted by claims about what follows from what. But is logic also relevant to the normativity of agnostic attitudes? The question here is whether logical entailment also puts constraints on what kinds of things one can suspend judgment about. In this paper I address that question and I give a positive answer to it. In particular, I advance two logical (...) norms of agnosticism, where the first one allows us to assess situations in which the subject is agnostic about the conclusion of a valid argument and the second one allows us to assess situations in which the subject is agnostic about one of the premises of a valid argument.

Aesthetic subjectivism takes the truth of aesthetic judgments to be relative to the individual making that judgment. Despite widespread suspicion, however, this does not mean that one cannot be wrong about such judgments. Accordingly, this does not mean that one cannot gain higher-order evidence of error and fallibility that bears on the rationality of the aesthetic judgment in question. In this paper, we explain and explore these issues in some detail.

Deontological evidentialism is the claim that S ought to form or maintain S’s beliefs in accordance with S’s evidence. A promising argument for this view turns on the premise that consideration c is a normative reason for S to form or maintain a belief that p only if c is evidence that p is true. In this paper, I discuss the surprising relation between a recently influential argument for this key premise and the principle that ought implies can. I argue (...) that anyone who antecedently accepts or rejects this principle already has a reason to resist either this argument’s premises or its role in support of deontological evidentialism.

One of the few points of agreement between most theists and non-theists working on the problem of evil is that the existence of a perfect God is incompatible with the existence of pointless evil. In a series of influential papers, however, Peter van Inwagen has argued that careful attention to the reasoning behind this claim reveals fatal difficulties related to the Sorites Paradox. In this paper, I explain van Inwagen’s appeal to sorites reasoning, distinguish between two different arguments in his (...) work, and argue that they both commit the same so-far-unnoticed mistake.

In this Ph.D. dissertation, completed at the Sorbonne, it is shown that the whole of medieval philosophy was not reduced to a realist stance: in the 13th-14th centuries, an idealist stance emerged and was developed into a full-fledged epistemological idealism, personified in the philosophers Eckhart von Hochheim and Dietrich von Freiberg. This dissertation deviates from most works in the history of philosophy by proposing to see this as a taxonomy.

Deontological evidentialism is the claim that we ought to form and maintain our beliefs in accordance with our evidence. In this paper, I criticize two arguments in its defense. I begin by discussing Berit Broogard’s use of the distinction between narrow-scope and wide-scope requirements against W.K. Clifford’s moral defense of. I then use this very distinction against a defense of inspired by Stephen Grimm’s more recent claims about the moral source of epistemic normativity. I use this distinction once again to (...) argue that Hilary Kornblith’s criticism of Richard Feldman’s defense of is incomplete. Finally, I argue that Feldman’s defense is insensitive to the relation between normative requirements and privileged values: values that have normative authority over us. (shrink)

Why should we avoid incoherence? An influential view tells us that incoherent combinations of attitudes are such that it is impossible for all of those attitudes to be simultaneously vindicated by the evidence. But it is not clear whether this view successfully explains what is wrong with certain akratic doxastic states. In this paper I flesh out an alternative response to that question, one according to which the problem with incoherent combinations of attitudes is that it is impossible for all (...) of those attitudes to be simultaneously knowledgeable. This alternative response explains what is wrong with akratic combinations of attitudes using commonly accepted epistemological theses. The paper still shows how this proposal is able to explain the badness of incoherent combinations involving the absence of attitudes, suspended judgment and credence. These explanations deploy the notions of knowledge and being in a position to know, instead of the notion of responding properly to the evidence. Finally, I suggest that this picture can be generalized to the realm of practical rationality as well. (shrink)

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)

Hermeneutical injustices, according to Miranda Fricker, are injustices that occur “when a gap in collective interpretive resources puts someone at an unfair disadvantage when it comes to making sense of their social experiences” (Fricker 2007, 1). For Fricker, the relevant injustice in these cases is the very lack of knowledge and understanding experienced by the subject. In this way, hermeneutical injustices are instances of epistemic injustices, the kind of injustice that “wrongs someone in their capacity as a subject of knowledge” (...) (Fricker 2007, 5). In this paper, however, I identify different means by which our hermeneutic activities lead to social injustices, of both a practical and epistemic kind, and I identify different ways in which those injustices manifest themselves. Since Fricker’s use of the notion of “hermeneutical injustices” to denote a well-defined kind of injustice is rightfully well-established, I here refer to the more general kinds of injustices I have in mind as “hermeneutic injustices” instead.
