Several logical operators are defined as dual pairs, in different types of logics. Such dual pairs of operators also occur in other algebraic theories, such as mathematical morphology. Based on this observation, this paper proposes to define, at the abstract level of institutions, a pair of abstract dual and logical operators as morphological erosion and dilation. Standard quantifiers and modalities are then derived from these two abstract logical operators. These operators are studied both on sets of states and sets of (...) models. To cope with the lack of explicit set of states in institutions, the proposed abstract logical dual operators are defined in an extension of institutions, the stratified institutions, which take into account the notion of open sentences, whose satisfaction is parametrised by sets of states. A hint on the potential interest of the proposed framework for spatial reasoning is also provided. (shrink)

We present in this paper an abstract categorical logic based on an abstraction of quantifier. More precisely, the proposed logic is abstract because no structural constraints are imposed on models (semantics free). By contrast, formulas are inductively defined from an abstraction both of atomic formulas and of quantifiers. In this sense, the proposed approach differs from other works interested in formalizing the notion of abstract logic and of which the closest to our approach are the institutions, which in addition to (...) be semantics free do not also impose any syntactic contingencies on the structure of formulas. To define the semantical framework in which formulas will be interpreted, we propose to follow the idea from categorical logic which defines the semantical interpretation of formulas from context and as subobjects of an object of a given category. In the spirit of Lawvere’s hyperdoctrines, we use a more abstract notion which generalizes the notion of subobject, standard in category theory: Pitt’s prop-categories. Always in the spirit of categorical logic, we propose a sequent calculus of which we show correctness and completeness for all semantical frameworks defined over any prop-categories. We then study some conditions which allow us to get this completeness result for particular classes of prop-categories. (shrink)

Les detracteurs du materialisme le donnent pour poussiereux, triste, deplace, ennuyeux. C'est aussi la reputation de la philosophie. Que dire de leur histoire! L'auteur, qui, en trente annees de philosophie, n'a pas trouve matiere a s'ennuyer, propose au lecteur quelques elements pour en juger: du materialisme de l'Antiquite a celui du dix-septieme siecle, de celui des Lumieres aux materialismes historiques, il l'invite a decouvrir des lieux inapercus ou de nouvelles perspectives dans l'histoire de la philosophie. Ceux qui veulent rester philosophes (...) pourront savoir gre aux materialistes de ce que la philosophie leur doit. En compagnie d'Epicure et de Hobbes, de Marc-Aurele et de Cyrano, de Gassendi et de Marx, et d'autres plus clandestins, il y a encore matiere a s'instruire, a se divertir, a s'etonner. (shrink)

The roles of small and great books, and passionate yet well-considered writings in the general education of a “college” or “university” trained teacher are questions which should be turned back upon the historian as teacher and writer. Where resides the historian's classroom? Who are the students and how do teachers come to be? What subject matter should be used to prod and provoke an often dormant humanity awake? Professor Marc Bloch's work, his passion for history's rôles and its (...) voices from the past speaking to the present, had a Renaissance in the cauldron of World War II. Bloch's commitment to teaching and writing history, teaching about the forceful, or surprising and shocking, “presences” of history's supposed past-tense experiences, remains seminal to the historian's craft. Bloch's own voice from the past was forged in an intensity of present-time experience. Reflection was searing experience. Memory was “now” and remembrance was an accident of preservation for futures then unknown. These futures need to know of the experiences of former, fragile, personal and generational memories if the very same futures were to be lived more surely and securely. Marc Bloch's The Historian's Craft, remains a vindication of the human-centred, purposive roles of history in a general education. Moreover, this general education can now be said to cover the broad sweep of “secondary schooling” experiences. This sweep of schooling and post-schooling experiences is beginning, however tentatively and problematically, to extend itself into worlds of work, the futures of work and the academic futures or courses of higher education: the arena of tertiary and university education. In a not dissimilar fashion but in an even more intense spirit, Bloch's work, L’étrange défaite, examines the explosion and implosion of France and, in effect, Western Europe in the years, months and days leading up to the German offensive in the West of 10 May 1940. Bloch recognized that education and the failures to harness intellect, true intellectual freedom and innovative teaching weighed heavily upon the disastrous course of events in 1940. Professor Bloch's texts can serve two complementary purposes. First, his works, Strange Defeat and The Historian's Craft remain as significant, contemporary records of personal thoughts, argumentative methodologies, and recollections of world-shattering events. They constitute, quite literally, an historian's craft in action. Second, Bloch's texts can serve an equally valuable role where the writer seeks to take his reader through and beyond the immediate historical question, methodology or series of unravelling events into an intellectual duel which stands upon the historian's engagement with worlds, past and present. Questions and actions, makings and doings matter in this world. Understanding is not only a prime responsibility of the historian; it is a duty which might well prove dangerous. Given the above observations, this essay will seek to emphasize that world history and the teaching of broad histories of humanity recognizes few, if any, borders which seek to block or hold at bay the presentation of the “passport” known as understanding. Teaching history is much more than teaching civics or recognizing civilizational variety and its barbarous opposites. Teaching history is an act, however imperfect, of recognizing ourselves in time. My brother “schoolmasters”—when it came to the point, you did, for the most part, put up a magnificent fight. It was your goodwill which managed to create in many a sleepy secondary school, in many universities—prisoners of the worse routines the only form of education of which, perhaps, we can feel genuinely proud. I only hope that a day will come, and come soon, a day of glory and of happiness for France, when, liberated from the enemy, and freer than ever in our intellectual life, we may meet again for the mutual discussion of ideas. And when that happens, do you not think that, having learned from an experience so dearly purchased, you will find much to alter in the things you were teaching only a few years back? Strange Defeat, 142).1 What was at stake was a geological upheaval of thought …2. (shrink)

“History is the most dangerous compound yet contrived by the chemistry of intellect”: it was in response to these words by Paul Valéry that Marc Bloch, professor of economic history at the Sorbonne, after the defeat of 1940, began writing a book on “how and why history is studied.” He gave it the provisional title Apologie pour l'Histoire ou Métier d'historien translated into English as The Historian's Craft. In the spring of 1944, he was killed by a German (...) firing squad for his clandestine activity in the Resistance. The manuscript of his book remained incomplete. Having entered the world at the same time as the research organization of Annales in 1949, Bloch's book on history, posthumously published by Lucien Febvre, was read and used as a product of that organization, which did not yet exist, even as a project, at the time the book was written. The Historian's Craft was read mostly by historians, history professors, and history students. Despite its readership, Bloch had written it for a different public: persons of culture and action, that same audience that Annales had tried in vain to conquer in the thirties—Paul Valéry's public. The study of the genesis of the interrupted manuscript reveals the richness of the content of Bloch's book, so far underrated. This example of the two pages missing from the 1949 edition, can today be the start of a deeper meditation on history, historians, and philology (and on the documents that refer to them). (shrink)

Discussions on Marc Bloch usually focus on The Annales School, his comparative method, or his defence of a distinct historical science. In contrast, I emphasise his seldom-investigated ideas of what historical understanding should involve. I contend that Bloch distinguishes between three different ethical attitudes in studying people and ways of life from the past: scientific passivity; critical judgements; understanding. The task of the historian amounts to understanding other worlds in their own terms. This essay is an exploration (...) of Bloch’s methodology and what historical understanding is needed to do justice to cultures that belong to the past, both conceptually and practically. (shrink)

English summary: Marc Andre Wiegand analyzes the neo-Kantian premises of Gustav Radbruch's legal philosophy.

Standardly, epistemic peers regarding a given matter are said to be people of equal competence who share all relevant evidence. Alternatively, one can define epistemic peers regarding a given matter as people who are equally likely to be right about that matter. I argue that a definition in terms of likelihood captures the essence of epistemic peerhood better than the standard definition or any variant of it. What is more, a likelihood definition implies the truth of the central thesis in (...) the debate on peer disagreement, the so-called Equal Weight View, according to which we should give the opinions of our peers the same weight we give our own. Adopting a likelihood definition, however, does not end the debate on peer disagreement, because the alleged theoretical alternatives to the Equal Weight View, reinterpreted in the light of a likelihood definition, can in fact be shown to be compatible with this view—though the reinterpreted versions may appear less plausible than the original ones. (shrink)

The evidence that we get from peer disagreement is especially problematic from a Bayesian point of view since the belief revision caused by a piece of such evidence cannot be modelled along the lines of Bayesian conditionalisation. This paper explains how exactly this problem arises, what features of peer disagreements are responsible for it, and what lessons should be drawn for both the analysis of peer disagreements and Bayesian conditionalisation as a model of evidence acquisition. In particular, it is pointed (...) out that the same characteristic of evidence from disagreement that explains the problems with Bayesian conditionalisation also suggests an interpretation of suspension of belief in terms of imprecise probabilities. (shrink)

A commonly neglected feature of the so-called Equal Weight View, according to which we should give our peers’ opinions the same weight we give our own, is its prima facie incompatibility with the common picture of philosophy as an armchair activity: an intellectual effort to seek a priori knowledge. This view seems to imply that our beliefs are more likely to be true if we leave our armchair in order to find out whether there actually are peers who, by disagreeing (...) with us, force us to revise our beliefs. This article argues that the Equal Weight View should be spelled out in such a way that not only actual peer disagreement requires us to revise our beliefs, but also merely possible peer disagreement. This result is not a reductio ad absurdum of the view. Quite the opposite: it shows that the view is, contrary to appearance, compatible with our common way of doing philosophy. (shrink)

Unknown peers create a problem for those epistemologists who argue that we should be conciliatory in cases of peer disagreement. The standard interpretation of ‘being conciliatory’ has it that we should revise our opinions concerning a specific subject matter whenever we encounter someone who is as competent and well informed as we are concerning this subject matter (and thus is our peer) and holds a different opinion. As a consequence, peers whom we have never encountered and who are hence unknown (...) to us are not taken into account. This, however, appears odd; not only because it is an accidental matter which peers we happen to encounter and which not, but also because it would allow people to deliberately isolate themselves from any kind of intellectual exchange on the topic under consideration. The paper argues that we should take the problem of unknown peers seriously, and that disregarding the problem is an instance of the more general mistake of assuming that evidential quality and justified believability can be dealt with separately. Moreover, a solution to the problem of unknown peers is suggested. (shrink)

Dieser Text geht der Frage nach, ob und, wenn ja, inwieweit sich Gedankenexperimente in der praktischen Philosophie in ihrer Struktur und ihrer epistemischen Signifikanz von Gedankenexperimenten in der theoretischen Philosophie oder in den Naturwissenschaften unterscheiden. Anhand einer allgemeinen Strukturanalyse von Gedankenexperimenten wird dabei aufgezeigt, dass bei Gedankenexperimenten in der praktischen Philosophie zwar häufig die angemessene Bewertung eines zugrunde gelegten Szenarios im Zentrum steht und nicht, wie zum Beispiel in theoretischen Philosophie oft, dessen angemessene Beschreibung, dass dieser Unterschied aber kaum Auswirkungen (...) hat auf die prinzipielle Anwendbarkeit – abgesehen von einer bisher übersehenen Konsequenz: Man darf in einem Gedankenexperiment nicht annehmen, dass moralische, ästhetische oder entscheidungstheoretische Prinzipien in unterschiedlichen möglichen Welten verschieden sind. Andernfalls käme dem Gedankenexperiment keinerlei epistemische Signifikanz zu. (shrink)

In addition to addressing questions about drug therapy, sex therapy, suicide, and child psychiatry, among others, this up-to-date revision adds six new chapters discussing abuses in psychiatry in Japan and Nazi Germany; a conceptual analysis of what mental illness is; psychiatry as a profession; the ethical aspects of psychogeriatrics; and deinstitutionalization. This (...) book is essential reading for all mental health professionals. (shrink)

What is structural rationality? Specifically, what is the distinctive feature of structural requirements of rationality? Some philosophers have argued, roughly, that the distinctive feature of structural requirements is coherence. But what does coherence mean, exactly? Or, at least, what do structuralists about rationality have in mind when they claim that structural rationality is coherence? This issue matters for making progress in various active debates concerning rationality. In this paper, I analyze three strategies for figuring out what coherence means in the (...) debates on structural rationality. I argue that these strategies face problems. (shrink)

This paper delves into the striking parallels between the linguistic patterns of Large Language Models (LLMs) and the concepts of psychosis in Lacanian psychoanalysis. Lacanian theory, with its focus on the formal and logical underpinnings of psychosis, provides a compelling lens to juxtapose human cognition and AI mechanisms. LLMs, such as GPT-4, appear to replicate the intricate metaphorical and metonymical frameworks inherent in human language. Although grounded in mathematical logic and probabilistic analysis, the outputs of LLMs echo the nuanced linguistic (...) associations found in metaphor and metonymy, suggesting a mirroring of human linguistic structures. A pivotal point in this discourse is the exploration of “absolute metaphors”—core gaps in reasoning discernible in both AI models and human thought processes and central to the Lacanian conceptualization of psychosis. Despite the traditional divide between AI research and continental philosophy, this analysis embarks on an innovative journey, utilizing Lacanian philosophy to unravel the logic of AI, using concepts established in the continental discourse on logic, rather than the analytical tradition.

Scientists have long counseled against interpreting animal behavior in terms of human emotions, warning that such anthropomorphizing limits our ability to understand animals as they really are. Yet what are we to make of a female gorilla in a German zoo who spent days mourning the death of her baby? Or a wild female elephant who cared for a younger one after she was injured by a rambunctious teenage male? Or a rat who refused to push a lever for food (...) when he saw that doing so caused another rat to be shocked? Aren’t these clear signs that animals have recognizable emotions and moral intelligence? With _Wild Justice_ Marc Bekoff and Jessica Pierce unequivocally answer yes. Marrying years of behavioral and cognitive research with compelling and moving anecdotes, Bekoff and Pierce reveal that animals exhibit a broad repertoire of moral behaviors, including fairness, empathy, trust, and reciprocity. Underlying these behaviors is a complex and nuanced range of emotions, backed by a high degree of intelligence and surprising behavioral flexibility. Animals, in short, are incredibly adept social beings, relying on rules of conduct to navigate intricate social networks that are essential to their survival. Ultimately, Bekoff and Pierce draw the astonishing conclusion that there is no moral gap between humans and other species: morality is an evolved trait that we unquestionably share with other social mammals. Sure to be controversial, _Wild Justice_ offers not just cutting-edge science, but a provocative call to rethink our relationship with—and our responsibilities toward—our fellow animals. (shrink)

Marc Hauser puts forth the theory that humans have evolved a universal moral instinct, unconsciously propelling us to deliver judgments of right and wrong independent of gender, education, and religion. Combining his cutting-edge research with the latest findings in cognitive psychology, linguistics, neuroscience, evolutionary biology, economics, and anthropology, Hauser explores the startling implications of his provocative theory vis-à-vis contemporary bioethics, religion, the law, and our everyday lives.

This paper proposes a model of human uniqueness based on an unusual distinction between two contrasted kinds of political competition and political status: (1) antagonistic competition, in quest of dominance (antagonistic status), a zero-sum, self-limiting game whose stake—who takes what, when, how—summarizes a classical definition of politics (Lasswell 1936), and (2) synergistic competition, in quest of merit (synergistic status), a positive-sum, self-reinforcing game whose stake becomes “who brings what to a team’s common good.” In this view, Rawls’s (1971) famous virtual (...) “veil of ignorance” mainly conceals politics’ antagonistic stakes so as to devise the principles of a just, egalitarian society, yet without providing any means to enforce these ideals (Sen 2009). Instead, this paper proposes that human uniqueness flourished under a real “adapted veil of ignorance” concealing the steady inflation of synergistic politics which resulted from early humans’ sturdy egalitarianism. This proposition divides into four parts: (1) early humans first stumbled on a purely cultural means to enforce a unique kind of within-team antagonistic equality—dyadic balanced deterrence thanks to handheld weapons (Chapais 2008); (2) this cultural innovation is thus closely tied to humans’ darkest side, but it also launched the cumulative evolution of humans’ brightest qualities—egalitarian team synergy and solidarity, together with the associated synergistic intelligence, culture, and communications; (3) runaway synergistic competition for differential merit among antagonistically equal obligate teammates is the single politically selective mechanism behind the cumulative evolution of all these brighter qualities, but numerous factors to be clarified here conceal this mighty evolutionary driver; (4) this veil of ignorance persists today, which explains why humans’ unique prosocial capacities are still not clearly understood by science. The purpose of this paper is to start lifting this now-ill-adapted veil of ignorance, thus uncovering the tight functional relations between egalitarian team solidarity and the evolution of human uniqueness.

Richard Boyd’s Homeostatic Property Cluster Theory is becoming the received view of natural kinds in the philosophy of science. However, a problem with HPC Theory is that it neglects many kinds highlighted by scientific classifications while at the same time endorsing kinds rejected by science. In other words, there is a mismatch between HPC kinds and the kinds of science. An adequate account of natural kinds should accurately track the classifications of successful science. We offer an alternative account of natural (...) kinds that better recognizes the diversity of epistemic aims scientists have for constructing classifications. That account introduces the idea of a classificatory program and provides criteria for judging whether a classificatory program identifies natural kinds. (shrink)

The question of whether biologists should continue to use the Linnaean hierarchy has been a hotly debated issue. Invented before the introduction of evolutionary theory, Linnaeus's system of classifying organisms is based on outdated theoretical assumptions, and is thought to be unable to provide accurate biological classifications. Marc Ereshefsky argues that biologists should abandon the Linnaean system and adopt an alternative that is more in line with evolutionary theory. He traces the evolution of the Linnaean hierarchy from its introduction (...) to the present. He illustrates how the continued use of this system hampers our ability to classify the organic world, and then goes on to make specific recommendations for a post-Linnaean method of classification. Accessible to a wide range of readers by providing introductory chapters to the philosophy of classification and the taxonomy of biology, the book will interest both scholars and students of biology and the philosophy of science.

It seems that epistemically rational agents should avoid incoherent combinations of beliefs and should respond correctly to their epistemic reasons. However, some situations seem to indicate that such requirements cannot be simultaneously satisfied. In such contexts, assuming that there is no unsolvable dilemma of epistemic rationality, either (i) it could be rational that one’s higher-order attitudes do not align with one’s first-order attitudes or (ii) requirements such as responding correctly to epistemic reasons that agents have are not genuine rationality requirements. (...) This result doesn’t square well with plausible theoretical assumptions concerning epistemic rationality. So, how do we solve this puzzle? In this paper, I will suggest that an agent can always reason from infallible higher-order reasons. This provides a partial solution to the above puzzle. (shrink)

This volume contains a selection of essays in translation by the German philosopher and man of letters Ernst Bloch, on the philosophy of music. For Bloch - often simply assimilated to the Marxist tradition, but whose thought shows a strongly individual and idealist cast - music was a primary focus on reflection. His musical knowledge and expertise were of a very high order and he was well acquainted with many of the leading composers and theorists of music of (...) his time in Germany: even divorced from his philosophy his criticism remains of value and significance. Throughout, whether discussing the complex and varied relations between text and music, or questions relating to the 'expressive' as opposed to the 'descriptive' functions of music, Bloch is intent on elucidating and placing musical experience.

Many epistemologists have argued that there is some degree of independence between individual and collective reliability (e.g., Kitcher 1990; Mayo-Wilson, Zollman, and Danks 2011; Dunn 2018). The question, then, is: To what extent are the two independent of each other? And in which contexts do they come apart? In this paper, I present a new case confirming the independence between individual and collective reliability optimization. I argue that, in voting groups, optimizing individual reliability can conflict with optimizing collective reliability. This (...) can happen even if various conditions are held constant, such as: the evidence jurors have access to, the voting system, the number of jurors, some independence conditions between voters, and so forth. This observation matters in many active debates on, e.g., epistemic dilemmas, the wisdom of crowds, independence theses, epistemic democracy, and the division of epistemic labour. (shrink)

Epistemically immodest agents take their own epistemic standards to be among the most truth-conducive ones available to them. Many philosophers have argued that immodesty is epistemically required of agents, notably because being modest entails a problematic kind of incoherence or self-distrust. In this paper, I argue that modesty is epistemically permitted in some social contexts. I focus on social contexts where agents with limited cognitive capacities cooperate with each other (like juries).
