The AGM (Alchourrón-Gärdenfors-Makinson) model of belief change is extended to cover changes on sets of beliefs that are not closed under logical consequence (belief bases). Three major types of change operations, namely contraction, internal revision, and external revision are axiomatically characterized, and their interrelations are studied. In external revision, the Levi identity is reversed in the sense that one first adds the new belief to the belief base, and afterwards contracts its negation. It is argued that external revision (...) represents an intuitively plausible way of revising one's beliefs. Since it typically involves the temporary acceptance of an inconsistent set of beliefs, it can only be used in belief representations that distinguish between different inconsistent sets of belief.

Recent work has considered the problem of extending to the case of iterated belief change the so-called `Harper Identity' (HI), which defines single-shot contraction in terms of single-shot revision. The present paper considers the prospects of providing a similar extension of the Levi Identity (LI), in which the direction of definition runs the other way. We restrict our attention here to the three classic iterated revision operators--natural, restrained and lexicographic, for which we provide here the first collective (...) characterisation in the literature, under the appellation of `elementary' operators. We consider two prima facie plausible ways of extending (LI). The first proposal involves the use of the rational closure operator to offer a `reductive' account of iterated revision in terms of iterated contraction. The second, which doesn't commit to reductionism, was put forward some years ago by Nayak et al. We establish that, for elementary revision operators and under mild assumptions regarding contraction, Nayak's proposal is equivalent to a new set of postulates formalising the claim that contraction by ¬A should be considered to be a kind of `mild' revision by A. We then show that these, in turn, under slightly weaker assumptions, jointly amount to the conjunction of a pair of constraints on the extension of (HI) that were recently proposed in the literature. Finally, we consider the consequences of endorsing both suggestions and show that this would yield an identification of rational revision with natural revision. We close the paper by discussing the general prospects for defining iterated revision in terms of iterated contraction. (shrink)

A sketch of a way of characterizing multidimensional value commitments and the way they can come into conflict derived from my book Hard Choices is presented and applied to the question of how to characterize the relevance of identity to value commitments and conflict. The views of A.K. Sen and A. Bilgrami are examined in the light of these ideas.

Much of what we know we know through testimony, and knowing on the basis of testimony requires some degree of trust in speakers. Trust is therefore very valuable. But in trusting, we expose ourselves to risks of harm and betrayal. It is therefore important to trust well. In this paper, I discuss two recent cases of the betrayal of trust in (broadly) academic contexts: one involving hoax submissions to journals, the other faking an identity on social media. I consider (...) whether these betrayals suggest that we ought to be less trusting in contexts like these. I argue that we should not: the acquisition of knowledge is dependent on trust, and we cannot intentionally reduce the extent to which we trust in these kinds of contexts without risking destroying it utterly. Instead, we must trust in our epistemic networks and the way they work to filter out deception. (shrink)

Janna Thompson has outlined ‘the apology paradox’, which arises whenever people apologize for an action or event upon which their existence is causally dependent. She argues that a sincere apology seems to entail a wish that the action or event had not occurred, but that we cannot sincerely wish that events upon which our existence depends had not occurred. I argue that Thompson’s paradox is a backward-looking version of Parfit’s (forward-looking) ‘non-identity problem’, where backward- and forward-looking refer to the (...) perspective of an agent apologizing for or contemplating an action. The temporal perspective of the agent gives us the tools with which to dissolve the air of paradox which surrounds these problems. Each is best grasped from one temporal perspective, but the para- doxes arise when we attempt to examine it simultaneously from another. The evaluations appropriate to the apology paradox and the non-identity problem are therefore time-indexed. (shrink)

In 1997, a Scottish surgeon by the name of Robert Smith was approached by a man with an unusual request: he wanted his apparently healthy lower left leg amputated. Although details about the case are sketchy, the would-be amputee appears to have desired the amputation on the grounds that his left foot wasn’t part of him – it felt alien. After consultation with psychiatrists, Smith performed the amputation. Two and a half years later, the patient reported that his life had (...) been transformed for the better by the operation [1]. A second patient was also reported as having been satisfied with his amputation [2]. (shrink)

Deleuze's Difference and Repetition is a notoriously difficult work of philosophy. Moreover, it is a work of philosophy that has led to quite divergent interpretations. How are we to account for this phenomenon of generating such distinct interpretations and appropriations? In this article, I apply Deleuze's theory of problems, questions and individuation to Deleuze's text as a way of understanding the stylistic strategy of his writing. Given Deleuze's critique of identity and representation, he would fall into a performative contradiction (...) if his writing were designed to transmit an identical thought from sender to receiver such that the receiver then could be said to represent Deleuze's thought. Rather, I argue, Deleuze aims to write ‘machinic’ or ‘productive’ works that lead to the production of something new through the reader's encounter with the work. Not only does Difference and Repetition theorise the process of creative individuation in the production of beings, I contend, but it also forces the reader to undergo a process of creative individuation, through which they produce a non-identical double of the work in the process of their reading that then takes on a life of its own. It is this phenomenon of the book as a machine for producing difference, I contend, that helps to account for the tremendous creative fecundity it has generated in being appropriated by a wide variety of disciplines and practices.

G. W. F. Hegel sees Oedipus as an epitome of the philosophical quest for self-knowledge. In Hegel's readings of Oedipus, the latter becomes a distant reflection of the modern and mature Hegelian self, who consciously takes on this quest. Yet unlike Oedipus, whose search for the truth about his past is characterized by both metaphorical and literal blindness, the modern self knows itself, precisely because it understands its past and can thus appropriate and situate itself in relation to the present. (...) For Hegel, self-understanding entails grasping the proper relationship between past and present, which in turn necessitates acknowledging his own relationship to Oedipus. This essay examines Henrik Ibsen's turn to the Hegelian engagement with the past (Oedipus being one crucial moment in the Hegelian story of the history of self-consciousness), by focusing on one of the most enigmatic scenes in his 1866 drama,Peer Gynt, where the Norwegian protagonist is cast as Oedipus. The scene examines the drama's own past—through an engagement with a dramatic ancestor—and focuses on the influence of the past on fashioning modern European identity. Moreover, it offers a critique of how the past is utilized in the creation and consolidation of that identity. With this, Ibsen offers an implicit critique of Hegel's understanding of Oedipus, and his encounter with the Sphinx in particular. Revisiting Oedipus through its modern reception, Ibsen questions the act by which the past is revealed as such and is put to work in the service of a particular present. (shrink)

In a series of articles, Terry Horgan and Mark Timmons have argued that Richard Boyd’s defence of moral realism, utilizing a causal theory of reference, fails. Horgan and Timmons construct a twin Earth-style thought experiment which, they claim, generates intuitions inconsistent with the realist account. In their thought experiment, the use of (allegedly) moral terms at a world is causally regulated by some property distinct from that regulating their use here on Earth; nevertheless, Horgan and Timmons claim, it is intuitive (...) that the inhabitants of this world disagree with us in their moral claims. Since any disagreement would be merely verbal were the alleged moral facts identical to or constituted by different natural facts, the identity or constitution claim must be false. I argue that their argument fails. Horgan and Timmons’ thought experiment is underdescribed; when we fill out the details, I claim, we shall see that the challenge to moral realism fades away. I sketch two possible interpretations of the (apparently) moral claims of the inhabitants of moral Twin Earth. On one interpretation, they fail to disagree with us because they actually agree with us; on the other, they fail to disagree with us because they are not moralizers at all. Which interpretation is true, I argue, will depend on the facts that explain the differences between us and the inhabitants of moral twin Earth. (shrink)

This article uses the example of South Africa to explore how inequality, institutions, identity, and polarization interact. The first 15 years of the country’s constitutional democracy was characterized by a virtuous spiral fueled by hope that a thriving, inclusive society was in reach, an embrace of win-win cooperation, and a surge of civic confidence in the legitimacy of the public domain. The next 15 years witnessed rising discontent in response to continuing massive inequality and economic hardship – plus sustained (...) efforts by populist political entrepreneurs to use economic discontent to fuel identity-based polarization and weaken institutions. In both periods, contrary to the either/or discourse of much scholarship, change was fueled by the ways in which economic expectations and identity politics interacted with one another. Renewal of the political center needs both reforms that address economic imbalances and engagement at the level of ideas. (shrink)

The puzzle of resultant moral luck arises when we are disposed to think that an agent who caused a harm deserves to be blamed more than an otherwise identical agent who did not. One popular perspective on resultant moral luck explains our dispositions to produce different judgments with regard to the agents who feature in these cases as a product not of what they genuinely deserve but of our epistemic situation. On this account, there is no genuine resultant moral luck; (...) there is only luck in what evidence becomes available to observers. In this paper, I develop an evolutionary account of our inclination to take the results of actions as evidence for the mental states of agents, thereby explaining why the resulting intuitions are recalcitrant to correction. The account explains why the puzzle of resultant moral luck arises: because our disposition to take the harms agents cause as evidence of their mental states can produce intuitions which conflict with those that arise when we examine agents’ mental states without reference to the results of their actions. The account also helps to solve the puzzle of resultant moral luck, by providing a strong reason to ignore the intuitions caused by our disposition to regard actual harms as evidence of mental states. Since these intuitions arise using an unreliable proxy for agents’ mental states, they ought to be trumped by more reliable evidence. (shrink)

In this paper, we explore a specific variant of multicultural education inIsrael that developed within the dominant Jewish cultural identity, that isthe claim of Jews from Islamic countries (Mizrahi Jews) for educational autonomy. This demand arose against the backdrop of an aggressive nationalist ideology – Zionism – that claimed torepresent all Jews, and yet was too ambivalent toward its non-European Jewish subjects. The Mizrahi Jews' dual identity, as Jews and as products of the Arab culture, conflated with the (...) state's problematic self-conception as both Jewish and democratic. This phenomenon, apparently, is evidenced by the two types of multicultural responses that developed within the Mizrahi sector: a critical multiculturalism with a social-democratic character on the one hand, and an autonomist multiculturalism with fundamentalist featureson the other.

Commenting on Jean-Paul Sartre's theory of imagination, Paul Ricoeur argues that Sartre fails to address the productive nature of imaginative acts. According to Ricoeur, Sartre's examples show that he thinks of imagination in mimetic terms, neglecting its innovative and creative dimensions. Imagination, Ricoeur continues, manifests itself most clearly in fiction, wherein new meaning is created. By using fiction as the paradigm of imaginative activity, Ricoeur is able to argue against Sartre that the essence of imagination lies not in its ability (...) to reproduce absent objects, but rather in the ability to transform reality through creative acts. Motivated by the intuition that Sartre the writer could not have forgotten to address such crucial dimensions of imagination, I examine Sartre's philosophical and literary work, showing that not only does he develop a notion of productive imagination, he also puts this notion to work by articulating the relationship between imagination, narrative, and identity formation, well before Ricoeur advanced his narrative-identity theory. I argue that Sartre, like Ricoeur and MacIntyre, another representative of narrative-theory whose criticism of Sartre I address in this essay, views imagination and narrativity as necessary conditions for the formation of a coherent and meaningful sense of self.

I propose a modest Bayesian reductionism as an alternative to Quine's moderate confirmational holism. Employing only first-order predicate logic with identity and elementary probability theory, I present two models of confirmation for individual hypotheses within blocks of theoretical sentences. Testing these models, I consider: (1) the old evidence problem; (2) the raven paradox; (3) a version of the the thesis of underdetermination which says that the evidence never provides adequate epistemic grounds for deciding between rival theories; and (4) the (...) confirmation of modal conditionals.

In the wake of the spectacular success of Miranda Fricker's Epistemic Injustice, philosophers have paid a great deal of attention to testimonial injustice. Testimonial injustice occurs when recipients of testimony discount it in virtue of its source: usually, their social identity. The remedy for epistemic injustice is almost always listening better and giving greater weight to the testimony we hear, on most philosophers' implicit or explicit view. But Fricker identifies another kind of epistemic injustice: hermeneutical injustice. This kind of (...) injustice occurs when someone can't articulate their own experience or understand their situation for lack of the hermeneutical tools. There is a possible tension between these kinds of injustice, we suggest: sincere testimony may be misleading (may fail to identify significant harms the testfier is subject, or may fail to register its magnitude, or to categorize it as the kind of harm it is) in virtue of a lack of hermeneutical resources. This tension raises the possibility that there are situations in which experts - those who possess hermeneutical tools - may be able to correct the testimony of those who experience harms in virtue of their identity. In this paper, we identify possible cases in which epistemic injustice might be reduced through such correction: in which an increase in testimonial injustice might serve to decrease it in the longer run, for example. We also suggest how the obvious dangers of a too great readiness to see testimony as in need of expert correction might be mitigated, and how the expert might suggest corrections without ceasing to listen.

In a series of very influential papers, Dan Kahan argues for “the identity protective cognition thesis”: the claim that politically motivated reasoning is a major factor explaining current levels of polarization over matters of fact, especially in the US. An important part of his case consists of experimental data supporting the claim that ideological polarization is more extreme amongst more numerate individuals. In this paper, we take a close look at how precisely this “numeracy effect” is supposed to come (...) about. Working with Kahan’s own notion of motivated reasoning, we reconstruct the mechanism that according to him produces the effect. Surprisingly, it turns out to involve plenty of motivation to reason, but no motivated reasoning. This undermines the support he takes the numeracy effect to provide for the identity protective cognition hypothesis. (shrink)

I argue that “sampling” is at the heart of rabbinical hermeneutics. I argue further that anomalous monism—and specifically its arguments about token identity, of which sampling is one species—provides some insight into understanding the nature of rabbinical hermeneutics and religion, where truth is contingent on social judgment but is nevertheless objective. These points are illustrated through a close reading of the story of the oven of Aknai in the Bavli's Baba Metzia. I claim that rabbinic Judaism represents an early (...) attempt to integrate written texts into communicative processes, and thus frame the essay by comparing it to more recent computational technologies.

For two millennia calling oneself a Jew and confessing Jesus-Christ was perceived as nonsense. This is no longer the case. Jewish believers in Christ - “Messianics”, Catholics, Orthodox, and so forth - are now reclaiming their Jewish identity. Jewish Church is about imagining what their home in the Church would look like.

The present study tested the existence of a cognitive schema that guides people's evaluations of the likelihood that observed problem-solving processes will succeed. The hypothesised schema consisted of attributes that were found to distinguish between retrospective case reports of successful and unsuccessful real world problem solving (Lipshitz & Bar Ilan, 1996). Participants were asked to evaluate the likelihood of success of identical cases of problem solving that differed in the presence or absence of diagnosis, the selection of appropriate or inappropriate (...) solutions, and the pairing of diagnosis with appropriate or non-appropriate solutions. Consistent with the proposition, diagnosis affected perceived likelihood of success, albeit only when solution quality was held constant, and appropriate diagnosis with a compatible solution produced higher perceived likelihood of success than appropriate diagnosis with incompatible solutions. In addition, results showed that solution quality played a significant role, and that compatibility with a six-phase rational model of problem solving played no role in judging likelihood of success.

De Cruz and Levy, in their commentaries on Religion as make‐believe, present distinct questions that can be addressed by clarifying one core idea. De Cruz asks whether one can rationally assess the mental state of religious credence that I theorize. Levy asks why we should not explain the data on religious “belief” merely by positing factual beliefs with religious contents, which happen to be rationally acquired through testimony. To both, I say that having religious credences is p‐irrational: a purposeful departure (...) from rational thought and behavior, where the purpose in question is maintaining a group identity.

Providing effective feedback to patients in a rehabilitation training program is essential. As technologies are being developed to support patient training, they need to be able to provide the users with feedback on their performance. As there are various aspects on which feedback can be given, it is important to ensure that users are not overwhelmed by too much information given too frequently by the assistive technology. We created a rule-based set of guidelines for the desired hierarchy, timing, and content (...) of feedback to be used when stroke patients train with an upper-limb exercise platform which we developed. The feedback applies to both success on task completion and to the execution of compensatory movements, and is based on input collected from clinicians in a previous study. We recruited 11 stroke patients 1–72 months from injury onset. Ten participants completed the training; each trained with the rehabilitation platform in two configurations: with motor feedback and with no motor feedback. The two conditions were identical, except for the feedback content provided: in both conditions they received feedback on task success; in the MF condition they also received feedback on making undesired compensatory movements during the task. Participants preferred the configuration that provided feedback on both task success and quality of movement. This pilot experiment demonstrates the feasibility of a system providing both task-success and movement-quality feedback to patients based on a decision tree which we developed. (shrink)

This article responds to Neil Levy's recent suggestion that: (1) the use of pharmaceutical enhancers can be understood as promoting our authenticity, no matter which of the two main contemporary conceptions of authenticity we adopt; and that (2) we do not need to decide between these two rival models (the ‘self-discovery’ and the ‘self-creation’ conception) in order to assess the common worry that enhancements will undermine our authenticity. Levy's core argument is based on a comparison between cases of people with (...) ‘Gender Identity Disorder’ (GID) seeking sex reassignment surgery, and cases of enhancement via pharmaceuticals. While conceding the plausibility of Levy's claim (1), I offer reasons to resist (2), by pointing out structural differences between GID cases and some paradigmatic cases of pharmacological enhancement. I argue that these differences prevent the latter sort of cases from counting as authenticity-promoting on the self-discovery view. I conclude that Levy's proposed way of ‘breaking the stalemate’ in this debate is unsuccessful: we cannot avoid settling the dispute between the two models if we are to adequately address the authenticity worry about pharmacological enhancement.

In La Métaphore Vive, spatial understandings pervade much of Ricoeur’s discussion of metaphor in terms of proximity and distance, tension, substitution, displacement, change of location, image, the ‘open’ structure of words, closure, transparency and opaqueness. Yet this is usually where space is discussed within metaphor, and as a metaphor itself, rather than as a precondition or prior system of relations to language interacting with language. Based on reinterpretation of an aspect of Lévi-Strauss’ structuralist anthropology, diametric and concentric spaces are argued (...) to be such a prior system of relations to language, actively framing metaphor. This article examines the relevance of this prelinguistic spatial discourse to Ricoeur’s framework of metaphor and interrogation of the copula, influenced centrally by Heidegger. Concentric spatial assumed connection and diametric spatial assumed separation offer a framework for understanding, in Ricoeur’s words, the “conflict between identity and difference” in metaphor and early Heidegger’s existential spatiality.

We cannot simply observe that Emile Durkheim, Claude Lévi-Strauss, and Pierre Bourdieu all received philosophical training and subsequently asserted, in surprisingly similar terms, that escaping from philosophy or breaking away from philosophical modes of thought was a necessary condition for any research in the human and social sciences, without considering whether there might be a direct relationship between the sociological ethos and a particular attitude towards philosophy. The "rupture" with philosophyis never complete: the sociologists' conception of sociology is, on the (...) contrary, heavily influenced by the negative image they have of philosophy, which they always invoke as something to be avoided or a specter that must be exorcised. The sociological perception of philosophy thus constitutes a system of oppositions, a set of likes and dislikes deeply ingrained in the minds of practitioners in the human and social sciences, and which, so to speak, form the very foundation of the discipline and its definition of its identity. By reconstructing it, this article proposes a sociological analysis of the genesis, structure, and function of the sociological unconscious. (shrink)

To this day, the Italian Jewish literary postwar canon is undisputedly ruled by Primo Levi, Giorgio Bassani and Carlo Levi. This study of three major Italian Jewish women writers – Natalia Ginzburg, Clara Sereni and Lia Levi – highlights the presence in Italian literature of a subversive Jewish écriture feminine. These writers’ formal independence and subversive redeployment of narrative and thematic strategies not only consolidated a strong female voice in Italian literature but also produced a specific Italian (...) brand of Jewish literature. The following analysis shows how, through their literary ‘life miniatures’, Ginzburg, Sereni and Levi recentre the domestic everydayness of woman’s personal and historical experience, while, simultaneously, challenging the traditional representations of women’s positions within family and within the public space, as well as interrogating their Jewish identity vis-a-vis their country’s Fascist past. In particular, this article focuses on the way in which all three authors portray themselves as women trying to strike a balance between their Jewish identity and history alive only in the domestic space of their family lives, and their gender identity which is repressed by the patriarchal system both in the house and in the public arena. These women respond by moving ‘out’ of their homes, by exploring the city space – thus turning the ‘urban monster’ into a positive locus for women’s self-determination and political action – and by bonding with other women. Through a demasculinization of the city space, these memoirs re-elaborated notions of family, Judaism, private and historical memory, and they reinvented a poetics for the ‘small virtues’ of woman’s everyday existence while also pioneering a new space in literature that radically changed the direction of patriarchal Italian culture in the second half of the twentieth century.

The use of brain technology that contributes to psychological changes has spurred a debate about personal identity. Some argue that neurotechnology does not undermine personal continuity (Levy, 2011) while others argue that it does (Kreitmair, 2019; Schechtman, 2010). To make these assessments, commentators fail to identify psychological changes that cause personal discontinuity. In this paper, I present a view that identifies personal continuity with the maintenance of a self-concept. I argue that a concept of self requires the ability to (...) self-ascribe physical and psychological features and that the diachronic self emerges with self-ascriptions of features that require endurance over time. I maintain that an adequate concept of self does not depend on the maintenance of any particular combination of self-ascriptions and that it can be maintained despite even significant changes in psychological or physical traits. Finally, I apply the self-concept view to identify changes that can result in discontinuity of self. (shrink)

We investigate the indestructibility properties of strongly compact cardinals in universes where strong compactness suffers from identity crisis. We construct an iterative poset that can be used to establish Kimchi–Magidor theorem from (in The independence between the concepts of compactness and supercompactness, circulated manuscript), i.e., that the first n strongly compact cardinals can be the first n measurable cardinals. As an application, we show that the first n strongly compact cardinals can be the first n measurable cardinals while the (...) strong compactness of each strongly compact cardinal is indestructible under Levy collapses (our theorem is actually more general, see Sect. 3). A further application is that the class of strong cardinals can be nonempty yet coincide with the class of strongly compact cardinals while strong compactness of any strongly compact cardinal κ is indestructible under κ-directed closed posets that force GCH at κ.

In a paper in this journal, Neil Levy challenges Nicholas Agar’s argument for the irrationality of mind-uploading. Mind-uploading is a futuristic process that involves scanning brains and recording relevant information which is then transferred into a computer. Its advocates suppose that mind-uploading transfers both human minds and identities from biological brains into computers. According to Agar’s original argument, mind-uploading is prudentially irrational. Success relies on the soundness of the program of Strong AI—the view that it may someday be possible to (...) build a computer that is capable of thought. Strong AI may in fact be false, an eventuality with dire consequences for mind-uploading. Levy argues that Agar’s argument relies on mistakes about the probability of failed mind-uploading and underestimates what is to be gained from successfully mind-uploading. This paper clarifies Agar’s original claims about the likelihood of mind-uploading failure and offers further defense of a pessimistic evaluation of success. (shrink)

In 1935, when the U.S. Supreme Court’s new building opened and displayed the phrase “Equal Justice Under Law,” racial segregation was commonplace, as were barriers limiting opportunities for men and women of all colors to participate in economic and political life. The justices on the Court and the lawyers appearing before them reflected those facts; almost all were white men. Today, the Supreme Court’s inscription has become its motto, read as if it always referenced an understanding of equality that has (...) become central to the identity and the legitimacy of courts. The judiciary “looks” somewhat different than it did and, in a sense, has become more “representative” of the range of people appearing in courts. Given the role that courts had played in sustaining discrimination, the impression that courts ought to welcome everyone is a major achievement. Yet, to assess the impact of new judicial demographics requires analysis of other major alterations in U.S. courts—the influx of diverse litigants newly entitled to pursue legal claims; the economic barriers facing many claimants; the emergence of judiciaries as agency-like promoters of agendas; and the displacement of public adjudication through the privatization of dispute resolution. Studies of women as judges focus mostly on their rulings, but probing the “difference that difference makes” requires looking beyond judicial opinions. Courts in the United States have developed structural capacities to propose rules and legislation, create education programs, commission research and task forces, and lobby for resources. When women of all colors and men of color became lawyers and judges, they created affinity organizations and pressed courts to research court-based bias and to revise rules of ethics, doctrine, and practice. Those changes are part of the impact of diversification within the legal profession, as is the backlash against affirmative efforts to reform practices. Another difference of the last decades is that new rights have brought into court many claimants with limited means. Participatory participation remains elusive, while the “justice gap” is pervasive. Worse yet, in some jurisdictions, courts have served as “revenue centers,” using court-imposed assessments as income. Failure to pay “legal financial obligations” can result in suspension of driver’s licenses, the loss of voting rights, and other sanctions levied disproportionately on people who are poor and of color. Instead of being seen as fonts of fairness, courts are coming to be identified as sites of inequality. In addition, many courts have embraced alternative forms of dispute resolution that make both processes and outcomes less visible to the public. Through doctrine and rules, U.S. courts have shifted their own practices as well as enforced mandates imposed on consumers and employers that push them out of court and out of class or joint actions. In sum, the new faces on the bench ought not to obscure that the project of representation, inclusion, and equality is far from complete. The vivid inequalities in courts are problems for courts because such disparities undermine their ability to be places of justice. (shrink)

Este artigo tem como objetivo refletir sobre as modificações cognitivas e identitárias nos/dos sujeitos da sociedade digital – denominados aqui de sujeitos imersivos, no sentido proposto por Lucia Santaella. Para tanto, considera-se a hipótese de que a compreensão de conceitos como ciberespaço, cibercultura e virtualização exige, antecipadamente, o resgate do sentido de termos como virtual, real, realidade e atualidade. O marco teórico destaca principalmente os argumentos apresentados por Pierre Lévy e Giles Deleuze. Parte-se do questionamento da fronteira entre mente e (...) corpo, entre real e virtual. Posteriormente, são identificadas algumas mudanças provocadas pela virtualização e seus efeitos nos espaços escolares. Os procedimentos metodológicos são demarcados pela abordagem qualitativa com amparo na pesquisa bibliográfica. Os resultados indicam a emergência de um novo sujeito de aprendizagem com processos cognitivos distintos e novas demandas sociais. Estas condições impõem um redimensionamento dos saberes e atitudes dos professores e dos especialistas em educação. Os apontamentos finais sugerem a necessidade de intensificação dos estudos acerca da virtualização da sociedade contemporânea a fim de compreender as características identitárias dos sujeitos imersivos.

This paper analyzes the notion of a minimal belief change that incorporates new information. I apply the fundamental decisiontheoretic principle of Pareto-optimality to derive a notion of minimal belief change, for two different representations of belief: First, for beliefs represented by a theory –a deductively closed set of sentences or propositions–and second for beliefs represented by an axiomatic base for a theory. Three postulates exactly characterize Pareto-minimal revisions of theories, yielding a weaker set of constraints than the standard AGM postulates. (...) The Levi identity characterizes Pareto-minimal revisions of belief bases: a change of belief base is Pareto-minimal if and only if the change satisfies the Levi identity (for “maxichoice” contraction operators). Thus for belief bases, Pareto-minimality imposes constraints that the AGM postulates do not. Keywords: belief revision, decision theory.. (shrink)

The Ramsey test is a well-known way of establishing connections between belief revision postulates and axioms for conditionals (“if p, then q”). Pareto-minimal theory change corresponds exactly to three characteristic axioms of counterfactual systems: a theory revision operator that satisfies the Ramsey test validates these axioms if and only if the revision operator is Pareto-minimal.

In this paper we study AGM contraction and revision of rules using input/output logical theories. We replace propositional formulas in the AGM framework of theory change by pairs of propositional formulas, representing the rule based character of theories, and we replace the classical consequence operator Cn by an input/output logic. The results in this paper suggest that, in general, results from belief base dynamics can be transferred to rule base dynamics, but that a similar transfer of AGM theory change to (...) rule change is much more problematic. First, we generalise belief base contraction to rule base contraction, and show that two representation results of Hansson still hold for rule base contraction. Second, we show that the six so-called basic postulates of AGM contraction are consistent only for some input/output logics, but not for others. In particular, we show that the notorious recovery postulate can be satisfied only by basic output, but not by simple-minded output. Third, we show how AGM rule revision can be defined in terms of AGM rule contraction using the Levi identity. We highlight various topics for further research. (shrink)

We provide a formal study of belief retraction operators that do not necessarily satisfy the postulate. Our intuition is that a rational description of belief change must do justice to cases in which dropping a belief can lead to the inclusion, or ‘liberation’, of others in an agent's corpus. We provide two models of liberation via retraction operators: ρ-liberation and linear liberation. We show that the class of ρ-liberation operators is included in the class of linear ones and provide axiomatic (...) characterisations for each class. We show how any retraction operator can be ‘converted’ into either a withdrawal operator ) or a revision operator via the Harper Identity and the Levi Identity respectively. (shrink)

Third, we show how AGM rule revision can be defined in terms of AGM rule contraction using the Levi identity. We highlight various topics for further research. (shrink)

Two systems of belief change based on paraconsistent logics are introduced in this article by means of AGM-like postulates. The first one, AGMp, is defined over any paraconsistent logic which extends classical logic such that the law of excluded middle holds w.r.t. the paraconsistent negation. The second one, AGMo , is specifically designed for paraconsistent logics known as Logics of Formal Inconsistency (LFIs), which have a formal consistency operator that allows to recover all the classical inferences. Besides the three usual (...) operations over belief sets, namely expansion, contraction and revision (which is obtained from contraction by the Levi identity), the underlying paraconsistent logic allows us to define additional operations involving (non-explosive) contradictions. Thus, it is defined external revision (which is obtained from contraction by the reverse Levi identity), consolidation and semi-revision, all of them over belief sets. It is worth noting that the latter operations, introduced by S. Hansson, involve the temporary acceptance of contradictory beliefs, and so they were originally defined only for belief bases. Unlike to previous proposals in the literature, only defined for specific paraconsistent logics, the present approach can be applied to a general class of paraconsistent logics which are supraclassical, thus preserving the spirit of AGM. Moreover, representation theorems w.r.t. constructions based on selection functions are obtained for all the operations. (shrink)

In order to clarify the problems of iterated (global) belief change it is useful to study simple cases, in particular consecutive contractions by sentences that are both logically and epistemically independent. Models in which the selection mechanism is kept constant are much more plausible in this case than what they are in general. One such model, namely uniform specified meet contraction, has the advantage of being closely connected with the AGM model. Its properties seem fairly adequate for the intended type (...) of contraction. However, the revision operator based on it via the Levi identity collapses into an implausible operation that loses all old information when revising by new information. A weaker version, semi-uniform specified meet contraction, avoids the collapse but has the disadvantage of a remarkably weak logic. It is left as an open issue whether there is an intermediate class of contraction operators that yields a more satisfactory logic. (shrink)

Generalisations of theory change involving operations on arbitrary sets ofwffs instead of on belief sets (i.e., sets closed under a consequencerelation), have become known as base change. In one view, a base should bethought of as providing more structure to its generated belief set, whichmeans that it can be employed to determine the theory contraction operationassociated with a base contraction operation. In this paper we follow suchan approach as the first step in defining infobase change. We think of an infobase (...) as a finite set of wffs consisting of independently obtainedbits of information. Taking AGM theory change (Alchourrón et al. 1985) as the general framework, we present a method that uses the structure of aninfobase B to obtain an AGM theory contraction operation for contractingthe belief set Cn(B). Both the infobase and the obtained theory contraction operation then play a role in constructing a unique infobasecontraction operation. Infobase revision is defined in terms of an analogueof the Levi Identity, and it is shown that the associated theory revisionoperation satisfies the AGM postulates for revision. Because every infobaseis associated with a unique infobase contraction and revision operation, the method also allows for iterated base change. (shrink)

The article begins by examining two arguments used by Derrida in work published in 1967. The first claims against Lévi-Strauss that an empirical pattern of events cannot be injected into or superimposed onto an historical pattern claiming universality, for then there can be no disconfirmation of what is said. (This argument is used against Marxian history by some who write in the wake of Existentialism, Paul Roubiczek for instance.) The second claims against Foucault that he does not distinguish between reason (...) as part of thinking and language and reason as an empirical historical structure capable of modification along time. The article then discusses the use of very similar if not identical arguments in Derrida’s much more recent work on laws, Force of law. The intelligibility, the interpretability, of laws and their history comes after the laws, not before, and is thus not fully universalisable. (shrink)

Putting God First: Jewish Humanism after Heidegger tackles the challenge of maintaining Jewish identity in a world dominated by Western humanism. It argues that the Holocaust reflects more broadly on contemporary humanism than the Jewish world has ever dared to acknowledge. It advances the view that the establishment of the State of Israel presents a profound historical opportunity to disentangle Jewish thought from elements of the Western humanist tradition that threaten Jewish survival and conceal from view the plausibility of (...) core Jewish ideas and values. The work proposes that a healthy and peaceful relationship between Westernism and a robust Jewish identity can be achieved only by unraveling the two, and it presents a philosophical path for achieving this. Following a precise analysis of modern and postmodern thought that includes discussions of Immanuel Kant, Jacques Derrida, Michel Foucault, Ludwig Wittgenstein, George Steiner, Bruno Latour, Hannah Arendt, Jonathan Haidt, Daniel Kahneman, and others, the centerpiece of the book offers a close reading of the masterwork Being and Time, which Martin Heidegger composed in the period when his thought was gravitating toward his endorsement of Hitler and Nazism. This deep dive into Heidegger's ontological understanding of how the individual (Dasein) interacts with others in space and time yields a method for articulating the onto-theological meanings of key Jewish concepts such as the Nefesh (psyche), the Neshamah (soul), Tzelem Elohim (human being in God's image), Am Segulah, (Jewish chosenness), Shabbat, the Land of Israel, and more in texts such as the Tanya, the Sefat Emet, the Nefesh HaChayim, the Kedushat Levi, and in the writings of Rav Kook and the Maharal of Prague. Ultimately the book proposes a disentangled spiritual/political vision for a Jewish state that is characterized by the politics of Tikun Olam" -- From the publisher. (shrink)
