In his “Bridging mainstream and formal ontology”, Augusto (2021) gives an excellent analysis of Dietrich von Freiberg’s idea of using causality as a partitioning principle for upper ontologies. For this Dietrich’s notion of extrinsic principles is crucial. The question whether causation can and indeed should be used as a partitioning principle for ontologies is discussed using mathematics and physics as examples.

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

Dietrich von Hildebrand seeks to pursue the idea that the discipline of phenomenology can offer a way of surmounting what Kant saw as the intrinsic limitations of human metaphysical enquiry. In this book review of the 2021 edition of Hildebrand’s What is Philosophy?, Hildebrand’s train of thought is reconstructed in some detail, from his opening remarks about knowing in general through to his account of the intuition of essences, the question of objectivity, and the overarching purpose of philosophy. Hildebrand’s (...) argument culminates in the claim that philosophy is not only the fundamental activity of a mind turned toward God, but is properly a preamble to religious faith. The review concludes by raising a number of objections to Hildebrand’s version of phenomenological realism. (shrink)

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

It is sometimes alleged that the study of emotion and the study of value are currently pursued as relatively autonomous disciplines. As Kevin Mulligan notes, “the philosophy and psychology of emotions pays little attention to the philosophy of value and the latter pays only a little more attention to the former.” (2010b, 475). Arguably, the last decade has seen more of a rapprochement between these two domains than used to be the norm (cf. e.g. Roeser & Todd 2014). But there (...) still seems to be considerable potential for exchange and dialogue if the situation is compared with their intimate relationship in central strands of early realist phenomenology. The philosopher perhaps most representative of this ecumenical approach is Husserl’s early student Dietrich von Hildebrand (1889-1977). From the very early stages of his philosophical career, Hildebrand has developed one of the most original, comprehensive and nuanced accounts of emotions at whose core is a detailed examination of their connection to value. While his central concern with the ethical significance of our affective life is in many ways continuous with Scheler’s work and draws crucially on Reinach’s philosophy of mind, Hildebrand’s own reflections considerably expand on and substantially modify the picture of the ontology and normative role of emotions defended by these authors. In this article, I reconstruct Hildebrand’s view of emotions with a particular focus on those aspects which represent his most distinctive contribution to this subject. (shrink)

Seit wenigen Jahren erfreuen sich in den Lebenswissenschaften mehrere Theorien eines immer weitergehenden Einflusses, die unter Etikettierungen wie Systembiologie, Netzwerktheorie oder Signalomics nur scheinbar unabhängige Herangehensweisen an komplexe Zusammenhänge darstellen. Navigation ist der übergreifende Gedanke, der so unterschiedliche Gebiete wie Regelungstheorie, Entscheidungstheorie und Systemwissenschaft verbindet. Navigation als Lage- und Kursbestimmung nebst den zugehörigen Signalverarbeitungsprozessen und Steuerkommandos ist die Grundlage dessen, was lebende Organismen von der blo§en Ansammlung materieller Ingredienzien unterscheidet – von der molekularen Ebene bis zum Sozialverhalten. Denn stets stellen (...) sich Prozesse des Lebens als solche des Suchens, Kommunizierens, Disponierens und Vervollkommnens dar, ob es sich nun um die Regulation der Sauerstoffspannung im Blut oder die Organisation eines Ameisenvolkes handelt.

Das Internet bietet die Möglichkeit, eine beliebig große Anzahl von Personen durch unterschiedliche Formen der Deliberation und Beschlussfassung politisch einzubinden. Insbesondere im kommunalen Kontext wird die Online-Partizipation – etwa im Rahmen städtischer Bürgerhaushalte – bereits vielfach als Mittel erprobt, um die soziale Akzeptanz und Legitimität politischer Entscheidungen zu erhöhen. Die Legitimität demokratischer Verfahren hängt neben anderen Faktoren maßgeblich von der Konstitution des Demos und der damit festgelegten Allokation der Teilnahmerechte ab. In historischer Perspektive hat vor allem die Exklusion bestimmter Gruppen, (...) insbesondere von Frauen, Besitzlosen oder nichtweißen Personen, die Legitimität klassischer Offline-Verfahren, wie z. B. Parlamentswahlen, in Frage gestellt. Die neuen Formen der Online-Partizipation bergen hingegen – so die zentrale These des Aufsatzes – die Gefahr der Über-Inklusivität, weil sie häufig auf jegliche Zugangsbeschränkung verzichten. Selbst wenn die Verfahren, wie in der Praxis üblich, einen konsultativen Charakter haben und die politischen Entscheidungsträger formal nicht binden, führt ihre Offenheit zu Legitimationsproblemen. Daraus entsteht die Notwendigkeit, normative Kriterien für die Vergabe von Partizipationsrechten zu entwickeln, die den Besonderheiten der Online-Deliberation angemessen Rechnung tragen. (shrink)

Zusammenfassung Die im Dezember 2022 in Kraft getretene Erweiterung des Infektionsschutzgesetzes sieht vor, im Fall einer Pandemie knappe intensivmedizinische Ressourcen nach dem Kriterium der Überlebenswahrscheinlichkeit zu priorisieren. Der Aufsatz geht der Frage nach, ob der Vorwurf, diese Regelung setze Menschen mit Behinderung einer erheblichen Diskriminierungsgefahr aus, berechtigt ist. Nach einer kurzen Darstellung des im Infektionsschutzgesetz festgelegten Zuteilungsverfahrens wird zunächst das vielschichtige Konzept der Diskriminierung erörtert. Im Kontext der Allokation knapper intensivmedizinischer Ressourcen besteht vornehmlich das Risiko einer nichtintendierten Diskriminierung, die in (...) direkter wie auch indirekter Form erfolgen kann. Die Regelungen, die das Infektionsschutzgesetz trifft, bieten Menschen mit Behinderung einen vergleichsweise hohen Schutz vor direkter Diskriminierung. Dennoch müssen Menschen mit bestimmten Behinderungen gravierende Nachteile hinnehmen, weil sie im Fall einer COVID-19-Infektion absehbar eine geringere Überlebenswahrscheinlichkeit als gesunde Menschen haben. Eine indirekte Diskriminierung liegt aber nur dann vor, wenn für die Auferlegung disproportionaler Nachteile keine hinreichende Rechtfertigung angeführt werden kann. In modernen pluralistischen Gesellschaften, die durch tiefgreifende Wertkonflikte gekennzeichnet sind, sollten unterschiedliche ethische Theorien – darunter auch konsequentialistische Positionen – als mögliche Grundlage einer Rechtfertigung anerkannt werden. Im Ergebnis erweist sich der Vorwurf, eine am Kriterium der Überlebenswahrscheinlichkeit orientierte Zuteilung knapper intensivmedizinischer Ressourcen bewirke eine Diskriminierung von Menschen mit Behinderung, als nicht stichhaltig.

Precision medicine and molecular systems medicine (MSM) are highly utilized and successful approaches to improve understanding, diagnosis, and treatment of many diseases from bench-to-bedside. Especially in the COVID-19 pandemic, molecular techniques and biotechnological innovation have proven to be of utmost importance for rapid developments in disease diagnostics and treatment, including DNA and RNA sequencing technology, treatment with drugs and natural products and vaccine development. The COVID-19 crisis, however, has also demonstrated the need for systemic thinking and transdisciplinarity and the limits (...) of MSM: the neglect of the bio-psycho-social systemic nature of humans and their context as the object of individual therapeutic and population-oriented interventions. COVID-19 illustrates how a medical problem requires a transdisciplinary approach in epidemiology, pathology, internal medicine, public health, environmental medicine, and socio-economic modeling. Regarding the need for conceptual integration of these different kinds of knowledge we suggest the application of general system theory (GST). This approach endorses an organism-centered view on health and disease, which according to Ludwig von Bertalanffy who was the founder of GST, we call Organismal Systems Medicine (OSM). We argue that systems science offers wider applications in the field of pathology and can contribute to an integrative systems medicine by (i) integration of evidence across functional and structural differentially scaled subsystems, (ii) conceptualization of complex multilevel systems, and (iii) suggesting mechanisms and non-linear relationships underlying the observed phenomena. We underline these points with a proposal on multi-level systems pathology including neurophysiology, endocrinology, immune system, genetics, and general metabolism. An integration of these areas is necessary to understand excess mortality rates and polypharmacological treatments. In the pandemic era this multi-level systems pathology is most important to assess potential vaccines, their effectiveness, short-, and long-time adverse effects. We further argue that these conceptual frameworks are not only valid in the COVID-19 era but also important to be integrated in a medicinal curriculum. (shrink)

In a world in which emotions and feelings occupy a dominant place in daily human life and especially in decision-making circumstances, it is important for us to ask ourselves whether it is possible to talk about “new” ethics or “renewed ethics.” Actually, we do not face a re-creation of principles and values, but rather we face a need for deepening our understanding of human anthropology. Thinkers such as Dietrich von Hildebrand have proposed that affectivity can shed light on ethics (...) comprehension. By means of a study of some of the works of this contemporary philosopher, we state that ethics is the result of a harmony between a clear objective comprehension of reality and a straight comprehension of that reality within the sphere of an educated, formed and well-known affectivity of the human person, which would lead us beyond the common place understanding of ethics as something rigid and full of rules and restrictions. -/- En un mundo en el que las emociones y los sentimientos ocupan un lugar preponderante en la vida cotidiana de las personas y especialmente en las decisiones que toman, cabe preguntarnos si podemos hablar de una nueva ética o de una ética renovada. En realidad no nos enfrentamos a una recreación de nuevos principios y valores, sino a una necesidad de ahondar en la antropología de la persona humana. En esta profundización se ha revalorado el importante papel que juega la afectividad en la vida humana. Pensadores como Dietrich von Hildebrand han propuesto que la afectividad puede dar luces en la comprensión de la ética. A partir de un estudio de algunas de las obras de este filósofo contemporáneo proponemos que la ética vendría siendo el resultado de una armonía entre la clara comprensión objetiva de la realidad y una recta comprensión de dicha realidad dentro de una esfera afectiva educada, formada, y ante todo conocida por la propia persona, lo cual nos conduce más allá de una ética entendida muchas veces como algo rígido lleno de normas y restricciones.

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

The relations between ontology and information are many and fundamental, and they help us to understand the present gulf between (formal) ontology and (philosophical) Ontology: We can speak of respectively ontology-driven information and information-driven ontology as the focus on being informed vs. informed being. The question of whether these two (can) coincide is relevant to both fields, and in this article I elaborate on what needs to be addressed first of all to provide us with an answer: The form. This (...) core ontological concept rooting in Aristotelian metaphysics was central to philosophical ontology, in particular in Latin Scholasticism, when it was clearly put into relation with information as that which defines an entity. In this context, Dietrich of Freiberg synthesized this long debate in a way that matters not only to the philosophical effort of producing information-driven ontologies but also to the engineering constructs of ontology-driven information systems.

In this paper, I argue for the necessity of including what I call “categorical norms” in Thomas Aquinas’s account of the ground of obligation (normativity theory) by drawing on the value phenomenology of Dietrich von Hildebrand. A categorical norm is one conceptually irreducible to any non-normative concept and which obligates us irrespective of pre-existing aims, goals, or desires. I show that Thomistic normativity theory on any plausible reading of Aquinas lacks categorical norms and then raise two serious objections which (...) constitute master arguments against it. The upshot is that this theory requires reform. I end by proposing work remaining for such reform, namely, an expansion of the Thomistic metaphysic and anthropology. (shrink)

In recent decades, Western philosophy, including personalism, has had to face the question of how to respect the otherness of the personal Other, a challenge issued most famously by Emmanuel Levinas. In his Totality and Infinity, Levinas's conclusions about alterity are stark. The Other is beyond all conceptualization and precedes my activity as a subject. It is the Other who founds my own independent subjectivity as an "I."1 These are indeed radical conclusions, but they raise the question, Does the very (...) term Other itself fully capture the alterity Levinas wishes to do justice to? The term Other (autrui) has a certain unavoidable generality and abstractness to it. Any person who is not myself, the world's population minus one, can be referred to by this term. Yet the Other is always richly distinguished in each case, for each Other is unique. I will argue that the personalist philosophy of Dietrich von Hildebrand reveals that the alterity of the Other rests on the more fundamental uniqueness of the content of our personhood. This content, which is a value, is disclosed in love, and it is indicated in the personal name. It is the name that, better than the term Other, captures the alterity of the personal Other. (shrink)

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

Berthold of Moosburg had the whole Sapientiale by Thomas of York constantly at hand when writing his commentary on Proclus. Even thought Berthold never refers by name to the English Franciscan except in his tabula auctoritatum, where Thomas is registered as «Magister Thomas Anglicus minor», he quotes extensively and verbatim from the Sapientiale throughout his Expositio of Proclus; astoundingly, Berthold quotes more from Thomas than he does from his Dominican predecessors in the Teutonic Province, Albert the Great, Ulrich of Strassburg (...) and Dietrich of Freiberg. The following articles describes the presence of Thomas of York in Berthold of Moosburg’s Expositio super Elementationem theologicam. An appendix provides a systematic investigation of the relationship between the texts of the two authors. (shrink)

Phenomenologists turn to Augustine to remedy the neglect of life, love, and language in the Cartesian cogito: (1) concerning life, Edmund Husserl appropriates Augustine’s analysis of distentio animi, Edith Stein of vivo, and Hannah Arendt of initium; (2) concerning love, Max Scheler appropriates Augustine’s analysis of ordo amoris, Martin Heidegger of curare, and Dietrich von Hildebrand of affectiones; (3) concerning language, Ludwig Wittgenstein appropriates Augustine’s analysis of ostendere, Hans-Georg Gadamer of verbum cordis, and Jean-Luc Marion of confessio. Phenomenology’s non-Cartesian (...) Augustinianism can tell us something about phenomenology, namely that it is engaged in the project of recontextualizing the cogito, and something about Augustine, namely how radically different his project is than Descartes’s. Phenomenology presents an Augustine that is well positioned for the debates of our times concerning mind and world, desire and the human person, and language and embodiment. (shrink)

In psycho-clinical research the notion of spirituality acquires a semantic plurality. This equivocal and ambiguous connotation that characterizes this term represents an obstacle to the epistemic and methodological validity of research designs, recognized as the threat to construct validity. In order to overcome this difficulty, we introduce, from Dietrich von Hildebrand's phenomenology, the notions of intentionality and transcendence insofar as these are capable of accounting for the specific element of the spiritual-religious phenomenon and discriminating it from the other phenomena (...) or variables that may be included under the notion of spirituality. This conceptual elucidation task allows evaluating the legitimacy of the variable selection process and establishing why they are or are not representatives of the phenomenon of spiritual-religious experience.

Phenomenological realism, in the tradition of Dietrich von Hildebrand, is advanced as a promising methodology for a theistic philosophy of divine and human agency. Phenomenological realism is defended in contrast to the practice of historicalism -- the view that a philosophy of mind and God should always be done as part of a thoroughgoing history of philosophy, e.g. the use of examples in analytic theology should be subordinated to engaging the work of Kant and other great philosophers. The criticism (...) of theism based on forms of naturalism that give exclusive authority to the physical sciences is criticized from a phenomenological, realist perspective. (shrink)

This paper offers an explanation for why some parts of philosophy have made no progress. Philosophy has made no progress because it cannot make progress. And it cannot because of the nature of the phenomena philosophy is tasked with explaining—all of it involves consciousness. Here, it will not be argued directly that consciousness is intractable. Rather, it will be shown that a specific version of the problem of consciousness is unsolvable. This version is the Problem of the Subjective and Objective. (...) Then it is argued that the unsolvability of this latter problem is why there are other unsolvable philosophy problems. (shrink)

Does pre-voting group deliberation improve majority outcomes? To address this question, we develop a probabilistic model of opinion formation and deliberation. Two new jury theorems, one pre-deliberation and one post-deliberation, suggest that deliberation is beneficial. Successful deliberation mitigates three voting failures: (1) overcounting widespread evidence, (2) neglecting evidential inequality, and (3) neglecting evidential complementarity. Formal results and simulations confirm this. But we identify four systematic exceptions where deliberation reduces majority competence, always by increasing Failure 1. Our analysis recommends deliberation that (...) is 'participatory', 'neutral', but not necessarily 'equal', i.e., that involves substantive sharing, privileges no evidences, but might privilege some persons.

This paper argues for a noncognitiveist computationalism in the philosophy of mind. It further argues that both humans and computers have intentionality, that is, their mental states are semantical -- they are about things in their worlds.

There is a surprising disconnect between formal rational choice theory and philosophical work on reasons. The one is silent on the role of reasons in rational choices, the other rarely engages with the formal models of decision problems used by social scientists. To bridge this gap, we propose a new, reason-based theory of rational choice. At its core is an account of preference formation, according to which an agent’s preferences are determined by his or her motivating reasons, together with a (...) ‘weighing relation’ between different combinations of reasons. By explaining how someone’s preferences may vary with changes in his or her motivating reasons, our theory illuminates the relationship between deliberation about reasons and rational choices. Although primarily positive, the theory can also help us think about how those preferences and choices ought to respond to normative reasons. (shrink)

While ordinary decision theory focuses on empirical uncertainty, real decision-makers also face normative uncertainty: uncertainty about value itself. From a purely formal perspective, normative uncertainty is comparable to (Harsanyian or Rawlsian) identity uncertainty in the 'original position', where one's future values are unknown. A comprehensive decision theory must address twofold uncertainty -- normative and empirical. We present a simple model of twofold uncertainty, and show that the most popular decision principle -- maximising expected value (`Expectationalism') -- has different formulations, namely (...) Ex-Ante Expectationalism, Ex-Post Expectationalism, and hybrid theories. These alternative theories recommend different decisions, reasoning modes, and attitudes to risk. But they converge under an interesting (necessary and sufficient) condition. (shrink)

Under the independence and competence assumptions of Condorcet’s classical jury model, the probability of a correct majority decision converges to certainty as the jury size increases, a seemingly unrealistic result. Using Bayesian networks, we argue that the model’s independence assumption requires that the state of the world (guilty or not guilty) is the latest common cause of all jurors’ votes. But often – arguably in all courtroom cases and in many expert panels – the latest such common cause is a (...) shared ‘body of evidence’ observed by the jurors. In the corresponding Bayesian network, the votes are direct descendants not of the state of the world, but of the body of evidence, which in turn is a direct descendant of the state of the world. We develop a model of jury decisions based on this Bayesian network. Our model permits the possibility of misleading evidence, even for a maximally competent observer, which cannot easily be accommodated in the classical model. We prove that (i) the probability of a correct majority verdict converges to the probability that the body of evidence is not misleading, a value typically below 1; (ii) depending on the required threshold of ‘no reasonable doubt’, it may be impossible, even in an arbitrarily large jury, to establish guilt of a defendant ‘beyond any reasonable doubt’.

Advocates of dynamic systems have suggested that higher mental processes are based on continuous representations. In order to evaluate this claim, we first define the concept of representation, and rigorously distinguish between discrete representations and continuous representations. We also explore two important bases of representational content. Then, we present seven arguments that discrete representations are necessary for any system that must discriminate between two or more states. It follows that higher mental processes require discrete representations. We also argue that discrete (...) representations are more influenced by conceptual role than continuous representations. We end by arguing that the presence of discrete representations in cognitive systems entails that computationalism (i.e., the view that the mind is a computational device) is true, and that cognitive science should embrace representational pluralism.

People reason not only in beliefs, but also in intentions, preferences, and other attitudes. They form preferences from existing preferences, or intentions from existing beliefs and intentions, and so on. This often involves choosing between rival conclusions. Building on Broome (Rationality through reasoning, Hoboken, Wiley. https://doi.org/10.1002/9781118609088, 2013) and Dietrich et al. (J Philos 116:585–614. https://doi.org/10.5840/jphil20191161138, 2019), we present a philosophical and formal analysis of reasoning in attitudes, with or without facing choices in reasoning. We give different accounts of choosing, (...) in terms of a conscious activity or a partly subconscious process. Reasoning in attitudes differs fundamentally from reasoning _about_ attitudes, a form of theoretical reasoning in which one discovers rather than forms attitudes. We show that reasoning in attitudes has standard formal properties (such as monotonicity), but is indeterministic, reflecting choice in reasoning. Like theoretical reasoning, it need not follow logical entailment, but for a more radical reason, namely indeterminism. This makes reasoning in attitudes harder to model logically than theoretical reasoning. But it can be studied abstractly, using indeterministic consequence operators. (shrink)

The contemporary theory of epistemic democracy often draws on the Condorcet Jury Theorem to formally justify the ‘wisdom of crowds’. But this theorem is inapplicable in its current form, since one of its premises – voter independence – is notoriously violated. This premise carries responsibility for the theorem's misleading conclusion that ‘large crowds are infallible’. We prove a more useful jury theorem: under defensible premises, ‘large crowds are fallible but better than small groups’. This theorem rehabilitates the importance of deliberation (...) and education, which appear inessential in the classical jury framework. Our theorem is related to Ladha's (1993) seminal jury theorem for interchangeable (‘indistinguishable’) voters based on de Finetti's Theorem. We also prove a more general and simpler such jury theorem. (shrink)

While the importance of social norms for shaping and transforming communities is uncontested, their nature and normativity are controversial. Most recent theorists take social norms to arise if members hold certain attitudes, such as expectations on others, perhaps along with certain behaviours. Yet attitudes do not create norms, let alone social norms or social normativity. Social norms are instead ‘made’: through a social process. Social norming processes are special communication processes, often non-verbal and informal. We present different versions of a (...) process-based account of social norms and social normativity. The process-based view brings social norms closer to legal norms, as processes represent social ‘acts’, just as laws and contracts arise through acts rather than mere attitudes, for instances acts of voting or signing.

If a group is modelled as a single Bayesian agent, what should its beliefs be? I propose an axiomatic model that connects group beliefs to beliefs of group members, who are themselves modelled as Bayesian agents, possibly with different priors and different information. Group beliefs are proven to take a simple multiplicative form if people’s information is independent, and a more complex form if information overlaps arbitrarily. This shows that group beliefs can incorporate all information spread over the individuals without (...) the individuals having to communicate their (possibly complex and hard-to-describe) private information; communicating prior and posterior beliefs sufices.

This essay discusses the difficulty to reconcile two paradigms about beliefs: the binary or categorical paradigm of yes/no beliefs and the probabilistic paradigm of degrees of belief. The possibility for someone to hold both types of belief simultaneously is challenged by the lottery paradox, and more recently by a general impossibility theorem by Dietrich and List (2018, 2021). The nature, relevance, and implications of the tension are explained and assessed.

We present a new “reason-based” approach to the formal representation of moral theories, drawing on recent decision-theoretic work. We show that any moral theory within a very large class can be represented in terms of two parameters: a specification of which properties of the objects of moral choice matter in any given context, and a specification of how these properties matter. Reason-based representations provide a very general taxonomy of moral theories, as differences among theories can be attributed to differences in (...) their two key parameters. We can thus formalize several distinctions, such as between consequentialist and non-consequentialist theories, between universalist and relativist theories, between agent-neutral and agent-relative theories, between monistic and pluralistic theories, between atomistic and holistic theories, and between theories with a teleological structure and those without. Reason-based representations also shed light on an important but under-appreciated phenomenon: the “underdetermination of moral theory by deontic content”. (shrink)

Behaviourism is the view that preferences, beliefs, and other mental states in social-scientific theories are nothing but constructs re-describing people's behaviour. Mentalism is the view that they capture real phenomena, on a par with the unobservables in science, such as electrons and electromagnetic fields. While behaviourism has gone out of fashion in psychology, it remains influential in economics, especially in ‘revealed preference’ theory. We defend mentalism in economics, construed as a positive science, and show that it fits best scientific practice. (...) We distinguish mentalism from, and reject, the radical neuroeconomic view that behaviour should be explained in terms of brain processes, as distinct from mental states. (shrink)

Suppose several individuals (e.g., experts on a panel) each assign probabilities to some events. How can these individual probability assignments be aggregated into a single collective probability assignment? This article reviews several proposed solutions to this problem. We focus on three salient proposals: linear pooling (the weighted or unweighted linear averaging of probabilities), geometric pooling (the weighted or unweighted geometric averaging of probabilities), and multiplicative pooling (where probabilities are multiplied rather than averaged). We present axiomatic characterisations of each class of (...) pooling functions (most of them classic, but one new) and argue that linear pooling can be justified procedurally, but not epistemically, while the other two pooling methods can be justified epistemically. The choice between them, in turn, depends on whether the individuals' probability assignments are based on shared information or on private information. We conclude by mentioning a number of other pooling methods. (shrink)

Agents are often assumed to have degrees of belief (“credences”) and also binary beliefs (“beliefs simpliciter”). How are these related to each other? A much-discussed answer asserts that it is rational to believe a proposition if and only if one has a high enough degree of belief in it. But this answer runs into the “lottery paradox”: the set of believed propositions may violate the key rationality conditions of consistency and deductive closure. In earlier work, we showed that this problem (...) generalizes: there exists no local function from degrees of belief to binary beliefs that satisfies some minimal conditions of rationality and non-triviality. “Locality” means that the binary belief in each proposition depends only on the degree of belief in that proposition, not on the degrees of belief in others. One might think that the impossibility can be avoided by dropping the assumption that binary beliefs are a function of degrees of belief. We prove that, even if we drop the “functionality” restriction, there still exists no local relation between degrees of belief and binary beliefs that satisfies some minimal conditions. Thus functionality is not the source of the impossibility; its source is the condition of locality. If there is any non-trivial relation between degrees of belief and binary beliefs at all, it must be a “holistic” one. We explore several concrete forms this “holistic” relation could take. (shrink)

Through modern driver assistant systems, algorithmic decisions already have a significant impact on the behavior of vehicles in everyday traffic. This will become even more prominent in the near future considering the development of autonomous driving functionality. The need to consider ethical principles in the design of such systems is generally acknowledged. However, scope, principles and strategies for their implementations are not yet clear. Most of the current discussions concentrate on situations of unavoidable crashes in which the life of human (...) beings is existentially affected. In this paper, we argue that ethical considerations should be mandatory for any algorithmic decision of autonomous vehicles, instead of a limitation to hazard situations. Such an ethically aligned behavior is relevant because autonomous vehicles, like any other traffic participants, operate in a shared public space, where every behavioral decision impacts the operational possibilities of others. These possibilities concern the fulfillment of a road-user’s safety, utility and comfort needs. We propose that, to operate ethically in such space, an autonomous vehicle will have to take its behavior decisions according to a just distribution of operational possibilities among all traffic participants. Using an application on a partially-autonomous prototype vehicle, we describe how to apply and implement concepts of distributive justice to the driving environment and demonstrate the impact on its behavior in comparison to an advanced but egoistic decision maker.

Democratic decision-making is often defended on grounds of the ‘wisdom of crowds’: decisions are more likely to be correct if they are based on many independent opinions, so a typical argument in social epistemology. But what does it mean to have independent opinions? Opinions can be probabilistically dependent even if individuals form their opinion in causal isolation from each other. We distinguish four probabilistic notions of opinion independence. Which of them holds depends on how individuals are causally affected by environmental (...) factors such as commonly perceived evidence. In a general theorem, we identify causal conditions guaranteeing each kind of opinion independence. These results have implications for whether and how ‘wisdom of crowds’ arguments are possible, and how truth-conducive institutions can be designed. (shrink)

What is the relationship between degrees of belief and binary beliefs? Can the latter be expressed as a function of the former—a so-called “belief-binarization rule”—without running into difficulties such as the lottery paradox? We show that this problem can be usefully analyzed from the perspective of judgment-aggregation theory. Although some formal similarities between belief binarization and judgment aggregation have been noted before, the connection between the two problems has not yet been studied in full generality. In this paper, we seek (...) to fill this gap. The paper is organized around a baseline impossibility theorem, which we use to map out the space of possible solutions to the belief-binarization problem. Our theorem shows that, except in limiting cases, there exists no belief-binarization rule satisfying four initially plausible desiderata. Surprisingly, this result is a direct corollary of the judgment-aggregation variant of Arrow’s classic impossibility theorem in social choice theory. (shrink)

A group is often construed as one agent with its own probabilistic beliefs (credences), which are obtained by aggregating those of the individuals, for instance through averaging. In their celebrated “Groupthink”, Russell et al. (2015) require group credences to undergo Bayesian revision whenever new information is learnt, i.e., whenever individual credences undergo Bayesian revision based on this information. To obtain a fully Bayesian group, one should often extend this requirement to non-public or even private information (learnt by not all or (...) just one individual), or to non-representable information (not representable by any event in the domain where credences are held). I pro- pose a taxonomy of six types of ‘group Bayesianism’. They differ in the information for which Bayesian revision of group credences is required: public representable information, private representable information, public non-representable information, etc. Six corre- sponding theorems establish how individual credences must (not) be aggregated to ensure group Bayesianism of any type, respectively. Aggregating through standard averaging is never permitted; instead, different forms of geometric averaging must be used. One theorem—that for public representable information—is essentially Russell et al.’s central result (with minor corrections). Another theorem—that for public non-representable information—fills a gap in the theory of externally Bayesian opinion pooling. (shrink)

Replicating or exceeding human intelligence, not just in particular domains but in general, has always been a major goal of Artificial Intelligence (AI). We argue here that “human intelligence” is not only ill-defined, but often conflated with broader aspects of human psychology. Standard arguments for replicating it are morally unacceptable. We then suggest a reframing: that the proper goal of AI is not to replicate humans, but to complement them by creating diverse intelligences capable of collaborating with humans. This goal (...) renders issues of theory of mind, empathy, and caring, or community engagement, central to AI. It also challenges AI to better understand the circumstances in which human intelligence, including human moral intelligence, fails. (shrink)

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

In the emerging literature on judgment aggregation over logically connected proposi- tions, expert rights or liberal rights have not been investigated yet. A group making collective judgments may assign individual members or subgroups with expert know- ledge on, or particularly affected by, certain propositions the right to determine the collective judgment on those propositions. We identify a problem that generalizes Sen's 'liberal paradox'. Under plausible conditions, the assignment of rights to two or more individuals or subgroups is inconsistent with the (...) unanimity principle, whereby unanimously accepted propositions are collectively accepted. The inconsistency can be avoided if individual judgments or rights satisfy special conditions. (shrink)

How can the propositional attitudes of several individuals be aggregated into overall collective propositional attitudes? Although there are large bodies of work on the aggregation of various special kinds of propositional attitudes, such as preferences, judgments, probabilities and utilities, the aggregation of propositional attitudes is seldom studied in full generality. In this paper, we seek to contribute to filling this gap in the literature. We sketch the ingredients of a general theory of propositional attitude aggregation and prove two new theorems. (...) Our first theorem simultaneously characterizes some prominent aggregation rules in the cases of probability, judgment and preference aggregation, including linear opinion pooling and Arrovian dictatorships. Our second theorem abstracts even further from the specific kinds of attitudes in question and describes the properties of a large class of aggregation rules applicable to a variety of belief-like attitudes. Our approach integrates some previously disconnected areas of investigation. (shrink)

In response to recent work on the aggregation of individual judgments on logically connected propositions into collective judgments, it is often asked whether judgment aggregation is a special case of Arrowian preference aggregation. We argue for the converse claim. After proving two impossibility theorems on judgment aggregation (using "systematicity" and "independence" conditions, respectively), we construct an embedding of preference aggregation into judgment aggregation and prove Arrow’s theorem (stated for strict preferences) as a corollary of our second result. Although we thereby (...) provide a new proof of Arrow’s theorem, our main aim is to identify the analogue of Arrow’s theorem in judgment aggregation, to clarify the relation between judgment and preference aggregation, and to illustrate the generality of the judgment aggregation model.

We introduce a “reason-based” framework for explaining and predicting individual choices. It captures the idea that a decision-maker focuses on some but not all properties of the options and chooses an option whose motivationally salient properties he/she most prefers. Reason-based explanations allow us to distinguish between two kinds of context-dependent choice: the motivationally salient properties may (i) vary across choice contexts, and (ii) include not only “intrinsic” properties of the options, but also “context-related” properties. Our framework can accommodate boundedly rational (...) and sophisticatedly rational choice. Since properties can be recombined in new ways, it also offers resources for predicting choices in unobserved contexts. (shrink)

This paper examines three cases of the clash between science and philosophy: Zeno’s paradoxes, the Frame Problem, and a recent attempt to experimentally refute skepticism. In all three cases, the relevant science claims to have resolved the purported problem. The sciences, construing the term broadly, are mathematics, artificial intelligence, and psychology. The goal of this paper is to show that none of the three scientific solutions work. The three philosophical problems remain as vibrant as ever in the face of robust (...) scientific attempts to dispel them. The paper concludes by examining some consequences of this persistence.

The aggregation of individual judgments over interrelated propositions is a newly arising field of social choice theory. I introduce several independence conditions on judgment aggregation rules, each of which protects against a specific type of manipulation by agenda setters or voters. I derive impossibility theorems whereby these independence conditions are incompatible with certain minimal requirements. Unlike earlier impossibility results, the main result here holds for any (non-trivial) agenda. However, independence conditions arguably undermine the logical structure of judgment aggregation. I therefore (...) suggest restricting independence to premises, which leads to a generalised premise-based procedure. This procedure is proven to be possible if the premises are logically independent. (shrink)
