This paper is about the alethic aspect of epistemic rationality. The most common approaches to this aspect are either normative (what a reasoner ought to/may believe?) or evaluative (how rational is a reasoner?), where the evaluative approaches are usually comparative (one reasoner is assessed compared to another). These approaches often present problems with blindspots. For example, ought a reasoner to believe a currently true blindspot? Is she permitted to? Consequently, these approaches often fail in describing a situation of alethic maximality, (...) where a reasoner fulfills all the alethic norms and could be used as a standard of rationality (as they are, in fact, used in some of these approaches). I propose a function α, which accepts a set of beliefs as inputand returns a numeric alethic value. Then I use this function to define a notion of alethic maximality that is satisfiable by finite reasoners (reasoners with cognitive limitations) and does not present problems with blindspots. Function α may also be used in alethic norms and evaluation methods (comparative and non-comparative) that may be applied to finite reasoners and do not present problems with blindspots. A result of this investigation isthat the project of providing purely alethic norms is defective. The use of function α also sheds light on important epistemological issues, such as the lottery and the preface paradoxes, and the principles of clutter avoidance and reflection. (shrink)

Bayesian epistemologists support the norms of probabilism and conditionalization using Dutch book and accuracy arguments. These arguments assume that rationality requires agents to maximize practical or epistemic value in every doxastic state, which is evaluated from a subjective point of view (e.g., the agent’s expectancy of value). The accuracy arguments also presuppose that agents are opinionated. The goal of this paper is to discuss the assumptions of these arguments, including the measure of epistemic value. I have designed AI agents based (...) on the Bayesian model and a nonmonotonic framework and tested how they achieve practical and epistemic value in conditions in which an alternative set of assumptions holds. In one of the tested conditions, the nonmonotonic agent, which is not opinionated and fulfills neither probabilism nor conditionalization, outperforms the Bayesian in the measure of epistemic value that I argue for in the paper (α-value). I discuss the consequences of these results for the epistemology of rationality. (shrink)

All reasoners described in the most widespread models of a rational reasoner exhibit logical omniscience, which is impossible for finite reasoners (real reasoners). The most common strategy for dealing with the problem of logical omniscience is to interpret the models using a notion of beliefs different from explicit beliefs. For example, the models could be interpreted as describing the beliefs that the reasoner would hold if the reasoner were able reason indefinitely (stable beliefs). Then the models would describe maximum rationality, (...) which a finite reasoner can only approach in the limit of a reasoning sequence. This strategy has important consequences for epistemology. If a finite reasoner can only approach maximum rationality in the limit of a reasoning sequence, then the efficiency of reasoning is epistemically (and not only pragmatically) relevant. In this paper, I present an argument to this conclusion and discuss its consequences, as, for example, the vindication of the principle 'no rationality through brute-force'. (shrink)

I propose the notion of ‘epistemic sanity’, a property of parsimony between the holding of true but not false beliefs and the consideration of our cognitive limitations. Where ‘alethic value’ is the epistemic value of holding true but not false beliefs, the ‘alethic potential’ of an agent is the amount of extra alethic value that she is expected to achieve, given her current environment, beliefs, and reasoning skills. Epistemic sanity would be related to the holding of (true or false) beliefs (...) that increase the agent's alethic potential (relevant beliefs) but not of beliefs that decrease it (this is related to cognitive parsimony). Suspension of judgment, forgetting, and clutter avoidance are the main contributors to an agent's epistemic sanity, where this paper focuses on suspension. I argue that rational suspension favors the holding of true and relevant beliefs, which is not the case for the extremes of opinionation (no suspension) and skepticism (general suspension). In the absence of evidence, opinionated agents are often forced to rely on principles such as the principle of indifference, but suspension dominates indifference in terms of alethic value in some conditions. A rational agent would only find it beneficial to adopt skepticism if she considers herself to be an anti-expert about her entire agenda, but then ‘flipping’ beliefs maximizes expected alethic value in relation to skepticism. The study of epistemic sanity results in an ‘impure’ veritism, which can deal with some limitations of veritism (e.g., explaining the existence of false but relevant beliefs). (shrink)

The causal and simulation theories are often presented as very distinct views about declarative memory, their major difference lying on the causal condition. The causal theory states that remembering involves an accurate representation causally connected to an earlier experience. In the simulation theory, remembering involves an accurate representation generated by a reliable memory process. I investigate how to construe detailed versions of these theories that correctly classify memory errors as misremembering or confabulation. Neither causalists nor simulationists have paid attention to (...) memory-conjunction errors, which is unfortunate because both theories have problems with these cases. The source of the difficulty is the background assumption that an act of remembering has one target. I fix these theories for those cases. The resulting versions are closely related when implemented using tools of information theory, differing only on how memory transmits information about the past. The implementation provides us with insights about the distinction between confabulatory and non-confabulatory memory, where memory-conjunction errors have a privileged position. (shrink)

The most widespread models of rational reasoners (the model based on modal epistemic logic and the model based on probability theory) exhibit the problem of logical omniscience. The most common strategy for avoiding this problem is to interpret the models as describing the explicit beliefs of an ideal reasoner, but only the implicit beliefs of a real reasoner. I argue that this strategy faces serious normative issues. In this paper, I present the more fundamental problem of logical omnipotence, which highlights (...) the normative content of the problem of logical omniscience. I introduce two developments of the notion of implicit belief (accessible and stable belief ) and use them in two versions of the most common strategy applied to the problem of logical omnipotence.

Backtracking counterfactuals are problem cases for the standard, similarity based, theories of counterfactuals e.g., Lewis. These theories usually need to employ extra-assumptions to deal with those cases. Hiddleston, 632–657, 2005) proposes a causal theory of counterfactuals that, supposedly, deals well with backtracking. The main advantage of the causal theory is that it provides a unified account for backtracking and non-backtracking counterfactuals. In this paper, I present a backtracking counterfactual that is a problem case for Hiddleston’s account. Then I propose an (...) informational theory of counterfactuals, which deals well with this problem case while maintaining the main advantage of Hiddleston’s account. In addition, the informational theory offers a general theory of backtracking that provides clues for the semantics and epistemology of counterfactuals. I propose that backtracking is reasonable when the state of affairs expressed in the antecedent of a counterfactual transmits less information about an event in the past than the actual state of affairs.

Nesse artigo, investigo três casos de erros de memória obtidos em laboratório como forma de avaliar as principais teorias da memória : teoria causal e simulacionismo. De maneira geral, a teoria causal afirma que alguém lembra de algo somente se sua lembrança está numa relação causal adequada com uma experiência anterior daquilo que é lembrado. No simulacionismo, essa relação não é necessária. Os casos de erros de memória investigados são DRM, “perdido no shopping” e erro de conjunção de conteúdo. Esses (...) casos são difíceis para a teoria causal, especialmente em sua versão direta, mas não para o simulacionismo. Minha hipótese é a de que essa dificuldade se deve especificamente ao critério causal adotado. ENGLISH: I investigate three lab cases of memory error and test their consequences to the main theories of (declarative) memory: causal theory and simulationism. Roughly, the causal theory states that a subject remembers something only if her remembering is in a causal relation with a past experience of that thing. In simulationism, this relation is not necessary. The cases of memory error are DRM, “lost in the mall”, and memory -conjunction error. These are problem cases for the causal theory, but not for simulationism. My hypothesis is that this difficulty is because of the causal requirement. (shrink)

The negative zombie argument concludes that physicalism is false from the premises that p ∧¬q is ideally negatively conceivable and that what is ideally negatively conceivable is possible, where p is the conjunction of the fundamental physical truths and laws and q is a phenomenal truth (Chalmers 2002; 2010). A sentence φ is ideally negatively conceivable iff φ is not ruled out a priori on ideal rational reflection. In this paper, I argue that the negative zombie argument is neither a (...) priori nor conclusive. First, I argue that the premises of the argument are true only if there exists an adequate finite ideal reasoner R that believes ◊(p ∧ ¬q) on the basis of not believing p→q on a priori basis. Roughly, a finite reasoner is a reasoner with cognitive limitations (e.g. finite memory). I argue that R is finite only if R reasons nonmonotonically and only approach ideal reflection at the limit of a reasoning sequence. This would render the argument nonconclusive. Finally, I argue that, for some q, R does not believe ◊(p ∧ ¬q) on the basis of not believing p→q on a priori basis (e.g. for q =‘something is conscious’). This would render the choice of an adequate q dependent on empirical information (and the argument a posteriori). I conclude that the negative zombie argument (and, maybe, all zombie arguments) is neither a priori nor conclusive. (shrink)

Um argumento recorrente contra a liberalização do aborto parte do pressuposto de que, desde o momento da fertilização, seres humanos são indivíduos (no sentido de serem algo que necessariamente ocorre em uma entidade apenas). Nesse artigo, argumento que esse não é um caso a partir da possibilidade de geminação monozigótica e do fato de identidades serem necessárias. Defendo as premissas do argumento e discuto as possíveis interpretações de sua conclusão. Argumento que a interpretação completa da conclusão desse argumento está em (...) concordância com a conclusão de um argumento semelhante, que parte de noção de organismo. -/- ENGLISH: A common pro-life argument assumes that humans are individuals (in the sense that they necessarily occur in one entity only) from the moment of fertilization.

I argue that the correct interpretation of the conclusion of this argument is in agreement with the conclusion of a similar arguments from the notion of organism. (shrink)

Minimalists present solutions to these problems. In this paper, I argue that these solutions conflict with each other. I analyze some strategies to resolve this conflict.

There is a thesis that assure the computability between externalize about mental content and self-knowledge (BURGE, 1988). However, this theses, that explore the auto-verification property of claims of the type “I think that p”, works only for assertive claims that are express in the simple present tense. Among the problematic cases are the claims in the past tense and claims about specific propositional attitude. This fails about the thesis of the compatibility is pointed by Boghossian (1992) as a prove of (...) the incompatibility between externalism and self-knowledge. There is a wide bibliography that try to manage the claims in past tense. In these articles (BURGE, 1995), It's argued that the preservative function of memory assure the veracity of the claims in past tense (at last in normal situations). However, there isn't a lot of work about the problem of the claims about specific propositional attitude. This article propose a expanse the preservative memory theory, with the purpose that It manages the self-knowledge of past propositional attitudes. We propose some criteria that define when a claim of this type is true, mainly in the cases that the content of the attitude of the past thought is not identical with the actual thought. The criterion about the similarity of content is the Bernecker's one (2009). The criterion about similarity of attitudes is new: the attitude that S thinks in t1 as if he have had in t2 is similar with the attitude that he had in t 1 iff the actual attitude is entailed by the former.

The notion of an ideal reasoner has several uses in epistemology. Often, ideal reasoners are used as a parameter of (maximum) rationality for finite reasoners (e.g. humans). However, the notion of an ideal reasoner is normally construed in such a high degree of idealization (e.g. infinite/unbounded memory) that this use is unadvised. In this dissertation, I investigate the conditions under which an ideal reasoner may be used as a parameter of rationality for finite reasoners. In addition, I present and justify (...) the research program of computational epistemology, which investigates the parameter of maximum rationality for finite reasoners using computer simulations.

Abstract:The minimalist theory of truth (minimalism) consists in all instances of the T schema (‘‘φ’ is true iff φ’) along with the claim that our (primitive) acceptance of these instances is sufficient for explaining our attitudes (e.g. acceptance) in relation to all sentences involving ‘truth’ (‘true’, etc). Philosophers argue that minimalism can neither explain our atittudes in relation to truth-generalizations (generalizations involving ‘truth’) nor deal with the fact that instantiations of T to sentences alike the liar paradox entail a contradiction. Paul Horwich proposes solutions to the two problems, but these solutions conflict with each other. In this paper, I show demonstrate this conflict and analise some strategies to solve it. I argue that Horwich’s solution to the liar problem has important limitations. I conclude that the minimalism cannot avoid conflicts of this sort maintaining its minimalistic character. (shrink)

This article analyzes necropolitics as background of military action in peripheral regions of Brazil. With this, we propose a conceptual deepening about the term necropolitics and an analysis of its performance in The Brazilian territory, exemplified from news published by electronic newspapers between the years 2017 and 2020. For this, the figure of the sovereign will be taken in the light of the articulation between life and language, because with the expectation of pacifying society, a series of discourses are produced (...) with the intention of basing the image of the enemy and justifying the production of territories of deaths.

This paper aims to elucidate the emphatic demand of the Listening Pastoral inside the Catholic Church. The Supreme Pontiff, Pope Francis, dreams with a clergy with a greater capacity to handle the Christian community in its most relevant urgencies, such as youth accompaniment, specially an active listening made with attentive ears. From this base the article proposes a new method for accompaniment: a pastoral of listening according to the Humanistic Integrative Counseling model. However, the Listening Pastoral doesn’t have agents with (...) the required formation, therefore, beyond the technique, it is important the attitudes of the professional, who welcomes the marginalized and weakened. At the end of the article a list of attitudes will be presented having in mind a pastoral accompaniment. (shrink)

El artículo analiza la noción de amor en la filosofía de Spinoza a través del Tratado de la reforma del entendimiento, el Tratado breve y la Ética. El amor en Spinoza debe contextualizarse en su fenomenología crítica de los afectos y su teoría del conocimiento. Así es posible mostrar que, para Spinoza, cómo se ama —activa o pasiva-mente— es más importante que una distinción normativa entre objetos de amor correctos o incorrectos. Esta interpretación sobre el amor en Spinoza es coherente (...) con las premisas éticas y el monismo ontológico de su filosofía, y con su afirmación de que el amor es también una actividad de la Sustancia.

In this article, I propose a comparison between Natorp, Husserl, and Sellars that has a twofold aim. First, I ask to what extent Sellars’s perspective can be considered to be Neo-Kantian. Second, I demonstrate that the point of divergence among these three thinkers does not have to do with the role they ascribe to givenness in knowledge, but with the way they conceive the activity of thinking. Focusing on Husserl’s reading of Natorp’s theses concerning the subjective and objective ground of (...) knowledge, I show that both Natorp and Husserl agree with Sellars on the limits of a positivistic and empiricist perspective that relies on what is given in perception for the justification of one’s epistemic beliefs. On the other hand, the differences between the three thinkers emerge as soon as we consider how they attempt to integrate the spontaneity of thinking into the sphere of intuition from a renewed Kantian perspective.

This book is a highly original and provocative contribution to democratic theory.

I raise some questions about differentiations between methods, checking methods, and appropriate methods in terms of their modal profiles. Melchior argues that there can be sensitive checking methods which are not safe. I try to show that such methods are epistemically deficient. I introduce restricted sensitivity (RS) and investigate its checking profile. RS with respect to a proposition _p_ requires that we consider more non-p worlds (not just the closest ones) but not those which are irrelevant (outside a sphere of (...) seriously possible worlds). Restrictedly sensitive methods (vacuously sensitive and strongly safe) based on the appropriate type of Bayesian reasoning might be sufficient for some kind of “modest” checking. Melchior defends a uniform account of checking based on insensitivity even in the case of necessary true propositions and he introduces the apparatus of impossible worlds. I argue that an unsatisfactory method for checking a necessary true proposition is a way of reaching a belief in the target proposition (different from the original one) which might easily not have delivered a true one. I also indicate some limitations of the idea that checking (and knowing) is essentially modal in character. (shrink)

In gegenwärtigem sozialen Protest lässt sich, mit Eva von Redecker, eine „Revolution für das Leben“ ausmachen: eine neue Protestform, die sich durch einen Bezug auf bedrohtes Leben auszeichnet und die Vulnerabilität politisiert. Im vorliegenden Beitrag möchte ich mit John Dewey ein Verständnis von Politisierung durch sozialen Protest entwickeln und dieses in Bezug auf die „Revolution für das Leben“ erläutern. Dazu schlage ich vor, Politisierung als Problematisierung auf drei Ebenen zu begreifen. Sozialer Protest artikuliert, erstens, ausgehend von Erfahrungen, Sachverhalte als Probleme (...) von öffentlicher Bedeutung, die einer Lösung bzw. Bearbeitung bedürfen. Zweitens thematisiert er diese zugleich als Probleme zweiter Ordnung, d.i. als Probleme sozialer Institutionen und gesellschaftlicher (Selbst-) Gestaltung. Und schließlich stellt sozialer Protest die Grenzen politischer Gemeinschaft zur Disposition, indem er zugleich Probleme dritter Ordnung, d.i. politischer Teilhabe adressiert. In diesem Sinne ist auch die „Revolution für das Leben“ zu verstehen: sie artikuliert Vulnerabilität nicht nur als sachliches Problem des Schutzes von akut bedrohten Leben, sondern auch als soziales Problem gestaltbarer Praktiken der Sorge um verletzliche Leben sowie als politisches Problem des Ausschlusses aus der Gemeinschaft derjenigen, deren Leben als der Sorge und des Schutzes wert und würdig anerkannt werden.

Nietzsche est mort et c'est à nous à le faire vivre. Cet usage du texte n'est pas un retour à ce que Deleuze professait superbement : pour ce dernier, faire un enfant dans le dos (de Kant, de Bergson, voire de Nietzsche, même si Deleuze affirmait qu'avec ce dernier c'était l'inverse), c'était à la fois utiliser l'auteur pour lui faire dire ce qu'il n'avait explicitement pas dit, mais qui pouvait présenter un intérêt spéculatif, et, en même temps, dissimuler cet écart. (...) De fait, Deleuze disait "nous" ou "on", amalgamant ainsi sous le même pronom le commenté et le commentateur. Danilo Bilate, au contraire, revendique l'écart et le souligne tout au long de sa démonstration, rappelant ainsi sans cesse au lecteur que, s'il veut faire un enfant à Nietzsche, et si l'on nous permet de filer scabreusement la métaphore, c'est par-devant! Du même coup, là où Deleuze méprisait ouvertement toute philologie (jusqu'à ne pas même préciser les traductions utilisées), Danilo Bilate accorde à la terminologie nietzschéenne la plus grande attention. On interroge les textes pour ce qu'ils disent – car ils disent tout de même quelque chose par eux-mêmes si on veut bien les écouter. L'enfant qu'il s'agit de faire à Nietzsche en les écoutant est une éthique. Bertrand Binoche. (shrink)

What kind of causality does the Aristotelian Prime Mover exert on the heaven? Who “loves” the Prime Mover? Renaissance peripatetic philosopher, Francesco Vimercato, a “royal” teacher of “Greek and Latin philosophy” in Paris during the forties and the fifties of the 16th century tried to resolve these traditional puzzles that resulted from the exegesis of the Metaphysics XII, 6–7. His solution appears to be innovative, if compared to the ancient and the medieval ones. It seems partially to prefigure the last (...) two decades’ interpretations of Aristotelian “theology”.
