Severity as a moral qualifier of malady.Carl Tollef Solberg,Mathias Barra,Lars Sandman &BjornHoffmann -2023 -BMC Medical Ethics 24 (1):1-7.detailsThe overarching aim of this article is to scrutinize how severity can work as a qualifier for the moral impetus of malady. While there is agreement that malady is of negative value, there is disagreement about precisely how this is so. Nevertheless, alleviating disease, injury, and associated suffering is almost universally considered good. Furthermore, the strength of a diseased person’s moral claims for our attention and efforts will inevitably vary. This article starts by reflecting on what kind of moral impetus (...) malady incites. We then analyze how severity may qualify this impetus. We do so by discussing the relationship between severity and need, well-being and disvalue, death, urgency, rule of rescue, and distributive justice. We then summarize our thoughts about severity as a moral qualifier. We conclude that severity is, and should continue to be seen, as a morally significant concept that deserves continued attention in the future. (shrink)
Bread prices and sea levels: why probabilistic causal models need to be monotonic.VeraHoffmann-Kolss -2024 -Philosophical Studies (9):1-16.detailsA key challenge for probabilistic causal models is to distinguish non-causal probabilistic dependencies from true causal relations. To accomplish this task, causal models are usually required to satisfy several constraints. Two prominent constraints are the causal Markov condition and the faithfulness condition. However, other constraints are also needed. One of these additional constraints is the causal sufficiency condition, which states that models must not omit any direct common causes of the variables they contain. In this paper, I argue that the (...) causal sufficiency condition is problematic: (1) it is incompatible with the requirement that the variables in a model must not stand in non-causal necessary dependence relations, such as mathematical or conceptual relations, or relations described in terms of supervenience or grounding, (2) it presupposes more causal knowledge as primitive than is actually needed to create adequate causal models, and (3) if models are only required to be causally sufficient, they cannot deal with cases where variables are probabilistically related by accident, such as Sober’s example of the relationship between bread prices in England and the sea level in Venice. I show that these problems can be avoided if causal models are required to be monotonic in the following sense: the causal relations occurring in a model M would not disappear if further variables were added to M. I give a definition of this monotonicity condition and conclude that causal models should be required to be monotonic rather than causally sufficient. (shrink)
Pac Structures as Invariants of Finite Group Actions.Daniel MaxHoffmann &Piotr Kowalski -forthcoming -Journal of Symbolic Logic:1-36.detailsWe study model theory of actions of finite groups on substructures of a stable structure. We give an abstract description of existentially closed actions as above in terms of invariants and PAC structures. We show that if the corresponding PAC property is first order, then the theory of such actions has a model companion. Then, we analyze some particular theories of interest (mostly various theories of fields of positive characteristic) and show that in all the cases considered the PAC property (...) is first order.

Complete and Accurate? The Role of Profit Orientation in the Production of Public Health Data.Elina S.Hoffmann,Valerie J. Karplus &Erica R. H. Fuchs -2025 -Business and Society 64 (3):472-520.detailsPublic officials rely on performance data that are self-reported by organizations to evaluate progress on a wide range of prosocial outcomes. Policies that require public disclosure of performance in health care are thought to enable patients to select high-quality providers, which in turn may spur quality improvements as providers seek to protect their reputation or increase economic returns. Drawing on institutional theory that examines how conflicting institutional pressures influence organizational decisions, we theorize how profit orientation may mediate the response of (...) health care providers to disclosure mandates in a public health crisis. We focus on measures of data quality—completeness and accuracy—in self-reported data on COVID-19 status and outcomes generated by thousands of long-term care facilities. Using pooled regressions and a difference-in-differences style design, we find that overall, for-profit and not-for-profit facilities report similarly complete data but that for-profit facilities report less accurate data than their not-for-profit counterparts. Our results suggest that it may be important to incentivize each dimension of data quality separately to address differential institutional pressures that affect reporting practices. (shrink)

Reflective Consensus Building on Wicked Problems with the Reflect! Platform.Michael H. G.Hoffmann -2020 -Science and Engineering Ethics 26 (2):793-819.detailsWicked problems—that is, problems that can be framed in a number of different ways, depending on who is looking at them—pose ethical challenges for professionals that have scarcely been recognized as such. Even though wicked problems are all around us, they are rarely addressed in education. A reason for this failure might be that wicked problems pose almost insurmountable challenges in educational settings. This contribution shows how students can learn to cope with wicked problems in problem-based learning projects that are (...) structured by the Reflect! platform. (shrink)
Consensus Building and Its Epistemic Conditions.Michael H. G.Hoffmann -2019 -Topoi 40 (5):1173-1186.detailsMost of the epistemological debate on disagreement tries to develop standards that describe which actions or beliefs would be rational under specific circumstances in a controversy. To build things on a firm foundation, much work starts from certain idealizations—for example the assumption that parties in a disagreement share all the evidence that is relevant and are equal with regard to their abilities and dispositions. This contribution, by contrast, focuses on a different question and takes a different route. The question is: (...) What should people actually do who find themselves in deep disagreement with others? And instead of building theory on some “firm foundation,” the paper starts from a specific goal—building consensus by creating new proposals—and asks, first, which actions are suitable to achieve this goal and, second, what are the epistemic conditions of these actions. With regard to the latter, the paper focuses on what has been called framing and reframing in conflict research, and argues that both metaphors need and deserve a suitable epistemological conceptualization.

A philosophical view on singularity and strong AI.Christian HugoHoffmann -2023 -AI and Society 38 (4):1697-1714.detailsMore intellectual modesty, but also conceptual clarity is urgently needed in AI, perhaps more than in many other disciplines. AI research has been coined by hypes and hubris since its early beginnings in the 1950s. For instance, the Nobel laureate Herbert Simon predicted after his participation in the Dartmouth workshop that “machines will be capable, within 20 years, of doing any work that a man can do”. And expectations are in some circles still high to overblown today. This paper addresses (...) the demand for conceptual clarity and introduces precise definitions of “strong AI”, “superintelligence”, the “technological singularity”, and “artificial general intelligence” which ground in the work by the computer scientist Judea Pearl and the psychologist Howard Gardner. These clarifications allow us to embed famous arguments from the philosophy of AI in a more analytic context. (shrink)
Augustine, Thomas Aquinas, and Duns Scotus on the First Cause of Moral Evil.TobiasHoffmann -2023 -Quaestio 22:407-431.detailsWhile it is unproblematic that someone evil causes further evil, it is difficult to explain how a good person can cause his or her first evil act. Augustine, denying that something good can be the cause of evil, concludes that the first moral evil has only a ‘deficient cause’, not an efficient cause, which is to say that it has no explanation. By contrast, Aquinas and Scotus hold that the first moral evil has a cause, that the cause is something (...) good, and that it is an efficient cause: the will. For Aquinas, the will can cause its first evil act only if it is momentarily non-culpably deficient, in that it does not make the intellect actually consider the moral rule relevant to the choice. For Scotus, no such occurrent deficiency is presupposed in the will causing its first evil act; the will’s freedom suffices. Yet there is surprising agreement: at bottom, Aquinas and Scotus both trace the first moral evil to the will’s ability for alternatives and no further. Thus their view converges with Augustine’s claim that evil ultimately has no efficient cause. (shrink)
Paris vs. Prague: A “Suspicion of Fraud”: Ernst Mach Argues over Photographs and Epistemological Prerequisites.ChristophHoffmann -2016 -Science in Context 29 (4):409-427.detailsArgumentIn spring 1888, an anonymous critic raised severe doubts about Ernst Mach's and Peter Salcher's studies, published one year before, on the processes in the air caused by very rapid projectiles. Paraphrasing the experiments for the French popular science magazineLa Nature, the critic insinuated that the photographs upon which Mach and Salcher's argument were ostensibly based must have been of such low quality that they did not allow any well-founded conclusion. The critic did not deny the phenomena Mach and Salcher (...) had presented in their article; he denied that the photographs taken in the course of the experiments could permit any observation of the phenomena. I take the resulting quarrel as a window into the actors’ ideas on the requirements of “good observations” and the role of technical devices in this case. In particular I enquire how the various arguments relate to Lorraine Daston's and Peter Galison's framing of photography as an emblem of “mechanical objectivity.” We will see that in the case under debate, actors considered naked-eye observation, observation by telescope and photography mainly with regard to the challenges of the particular research object.

The map can be used in science education to show how the formulation of hypotheses should be related to a corresponding determination of experimental designs.
Bad Arguments and Objectively Bad Arguments.MichaelHoffmann &Richard Catrambone -2023 -Informal Logic 43 (1):23-90.detailsMany have argued that it is impossible to determine criteria to identify good arguments. In this contribution, we argue that it is at least possible to identify features of objectively bad arguments. Going beyond Blair and Johnson’s ARS criteria, which state that reasons must be acceptable, relevant, and sufficient, we develop a list of eight criteria with instructions for how to apply them to assess arguments. We conclude by presenting data from two empirical studies that show how frequently students violate (...) these criteria in lab conditions and “in the wild.”. (shrink)
Rationality applied: resolving the two envelopes problem.Christian HugoHoffmann -2023 -Theory and Decision 94 (4):555-573.detailsThe Two Envelopes Problem is a beautiful and quite confusing problem in decision theory which is ca. 35 years old and has provoked at least 150 papers directly addressing the problem and displaying a surprising variety of different responses. This paper finds decisive progress in an approach of Priest and Restall in 2003, contends that the recent papers having appeared since did not really go beyond that paper, argues further that Priest’s and Restall’s solution is still not complete, and proposes (...) a completion of their solution. If the analysis is correct, this work has the potential of laying the Two Envelopes Problem at rest. (shrink)
Questions sur la métaphysique by Jean Duns Scot.TobiasHoffmann -2022 -Journal of the History of Philosophy 60 (3):503-505.detailsThe Questions on Aristotle’s Metaphysics is Duns Scotus’s most important philosophical work. While Scotus’s obscurity is proverbial, that work adds additional layers of impenetrability, so much so that its fifteenth-century editor spoke of a chaos metaphysicum. In the last twenty-five years, scholars have brought a lot of clarity to this chaos, which is partly due to the difficulty of Scotus’s thought and writing style, and partly to the complicated textual tradition of this work. A further contribution to greater readability of (...) the Metaphysics commentary is being made by a research team under the direction of Olivier Boulnois, which is undertaking its French translation, enriched by valuable introductory material....

A New Model of Mathematics Education: Flat Curriculum with Self-Contained Micro Topics.MiklósHoffmann &Attila Egri-Nagy -2021 -Philosophies 6 (3):76.detailsThe traditional way of presenting mathematical knowledge is logical deduction, which implies a monolithic structure with topics in a strict hierarchical relationship. Despite many recent developments and methodical inventions in mathematics education, many curricula are still close in spirit to this hierarchical structure. However, this organisation of mathematical ideas may not be the most conducive way for learning mathematics. In this paper, we suggest that flattening curricula by developing self-contained micro topics and by providing multiple entry points to knowledge by (...) making the dependency graph of notions and subfields as sparse as possible could improve the effectiveness of teaching mathematics. We argue that a less strictly hierarchical schedule in mathematics education can decrease mathematics anxiety and can prevent students from ‘losing the thread’ somewhere in the process. This proposal implies a radical re-evaluation of standard teaching methods. As such, it parallels philosophical deconstruction. We provide two examples of how the micro topics can be implemented and consider some possible criticisms of the method. A full-scale and instantaneous change in curricula is neither feasible nor desirable. Here, we aim to change the prevalent attitude of educators by starting a conversation about the flat curriculum alternative. (shrink)
Axiomatisierung zwischen Platon und Aristoteles.MichaelHoffmann -2004 -Zeitschrift für Philosophische Forschung 58 (2):224 - 245.detailsGegenüber der in den letzten Jahrzehnten wiederholt vorgetragenen Kritik an der lange vorherrschenden Auffassung, dass erstmalig bei Aristoteles der Gedanke einer „Axiomatisierung“ wissenschaftlichen Wissens formuliert sei, ist es ein erstes Ziel des Artikels, die traditionelle Auffassung teilweise zu rehabilitieren, sie dabei aber weiter zu präzisieren. Ausgangspunkt dazu ist eine erst seit Hilbert üblich gewordene Unterscheidung zweier ganz verschiedener Auffassungen von Axiomatisierung: einer „logisch-analytischen“ und einer „modelltheoretischen“. Vor dem Hintergrund dieser Unterscheidung wird erstens gezeigt, dass man Aristoteles als den Begründer der (...) „logisch-analytischen“ Auffassung ansehen kann. Zweitens wird dafür argumentiert, dass in der vermutlich pseudo-platonischen „Epinomis“ eine „modelltheoretische“ Sicht der Axiomatisierung angedeutet ist. Ausgehend davon wird schließlich gezeigt, wie diese modelltheoretische Auffassung von Axiomatisierung zur Grundlage für ein neues Verständnis der in der Politeia diskutierten „Idee des Guten“ gemacht werden kann.

(1 other version)Be happy when your stomach is.DorotheaHoffmann -2020 -Pragmatics and Cognition 27 (1):184-208.detailsIn this paper I provide a description of the role of body-part terms in expressions of emotion and other semantic extensions in MalakMalak, a non-Pama-Nyungan language of the Daly River area. Body-based expressions denote events, emotions, personality traits, significant places and people and are used to refer to times and number. Particularly central in the language aremen‘stomach’,pundu‘head’ andtjewurr‘ear’ associated respectively with basic emotions, states of mind and reason. The figurative extensions of these body parts are discussed systematically, and compared with (...) what is known for other languages of the Daly River region. The article also explores the grammatical make up of body-based emotional collocations, and in particular the role of noun incorporation. In MalakMalak, noun incorporation is a central part of forming predicates with body parts, but uncommon in any other semantic domain of the language and only lexemes denoting basic emotions may also incorporate closed-class adjectives.

Breathing Life into Primal Beauty.Susan-JudithHoffmann -2020 -Fichte-Studien 48:293-304.detailsIn Über den Unterschied des Geistes u. des Buchstabens in der Philosophie, Fichte writes that man’s most fundamental tendency to philosophize is simply the drive to represent for the sake of representing—the same drive which is the ultimate basis of the fine arts. The process of representing for the sake of representing is grounded in “spirit”, which is nothing other than the power of the imagination to raise to consciousness images of das Urschöne. In this paper, I suggest that the (...) affinity between artistic activity and Fichte’s transcendental philosophy is closer than previously thought. I further suggest that for Fichte, transcendental philosophy is a performance and that such an interpretation of Fichte’s thought points to a way out of the circularity in his transcendental project.

Climate change, non-identity and moral ontology.Jonathan M.Hoffmann -2020 -Intergenerational Justice Review 5 (2).detailsMy students tend to rank Parfit’s Energy Policy and the Further Future1 among their favourite pieces. It is a marvellously argued, eye-opening paper. One of the most interesting passages comes right at the end, when Parfit suggests that we should act as if we had never realised that the non-identity problem exists: “When we are discussing social policies, should we ignore the point about personal identity? Should we allow ourselves to say that a choice like that of the Risky Policy (...) or of Depletion might be against the interests of people in the further future? This is not true. Should we pretend that it is? […] I would not want people to conclude that we can be less concerned about the more remote effects of our social policies. So I would be tempted to suppress the argument for this conclusion.” (2010 [1983], 119) In the paper, Parfit continuously stresses the implications of our views on personal identity. He differentiates between what he later, in his Reasons and Persons, calls a “narrow” and a “wide” person-affecting view (1984, ch. 18).2 On a narrow person-affecting view, we take seriously each person’s identity and assume that it is determined by its genome which is a product of a certain ovum and a certain sperm cell (112-113). On this view, we may then evaluate an action by considering its impact on each individual that is affected. An action is, thus, better or worse because it is better or worse for someone. Consequently, there may be alternative actions available to perform that seem better or worse, but aren’t really, as they are not better or worse for someone. One example that illustrates this point is the case of a 14 year-old who decides to have a child and, due to her age, gives the boy she conceives a bad start in life (113). In response, one may want to argue that she should have had a child later and that that child would have had a better start in life. This, however, overlooks that the boy that has been born to the young mother could not have been born later: the child she actually had could only come into existence because she decided to become a mother when she was 14. Hence, Parfit argues, we can “not claim that, in having this child, what she did was worse for him” (113, italics in the original). (shrink)
“Play it again, Sam”. A differentiating view on repeated exposure to narrative content in media.JellaHoffmann -2006 -Communications 31 (3):389-403.detailsWhereas repeated exposure to communication is a widespread phenomenon, it has so far received little attention in communication research. This article takes a step towards describing, differentiating, and explaining repeated exposure to communication. It discusses different forms of repeated exposure and then focuses on repeated exposure to narrative films. It explores possible motivations for reusing the same media content again and again, while taking processes of repeated exposure as well as situational and personal variables into account. The initially theoretical considerations (...) are then supported, expanded, and specified both by existent empirical evidence and findings from a focus group study. Finally, further questions about repeated exposure to narrative content in media are discussed. (shrink)

In this article, we argue that a de minimis threshold has no place in a normative theory of decision making, because the application of the principle will either recommend ignoring risks that should not be ignored (e.g., the sure death of a person) or it cannot be used by ordinary bounded and information-constrained (...) agents.

RoaldHoffmann on the philosophy, art, and science of chemistry.RoaldHoffmann -2012 - New York: Oxford University Press. Edited by Jeffrey Kovac & Michael Weisberg.detailsRoaldHoffmann's contributions to chemistry are well known; this Nobel laureate has published more than 500 articles and two books. As an "applied theoretical chemist," he has made significant contributions to our understanding of chemical bonding and reactivity, and taught two generations of chemists how to use molecular orbitals for real chemistry. Less well known, however, areHoffmann's important and insightful contributions to the areas of scholarship surrounding chemistry. Over a career that spans nearly fifty years, Roald (...) class='Hi'>Hoffmann has thought and written copiously about the broader context of chemistry and its relationship to the arts and poetry. This book containsHoffmann's essays and is organized around several major themes: chemical reasoning and explanation, writing and communicating in science, ethics, art and science, and chemical education. A few are unpublished lectures that are valuable additions to the volume. The editors have the full cooperation of RoaldHoffmann in this project. Most of the published work will be reprinted verbatim, but a few of the essays will be revised to eliminate redundancy. The unpublished lectures will also be edited since they were originally intended to be delivered orally at specific occasions. The editors will provide an introduction to the book, and some introductory material for each section. In introducing the material, they will highlight the intrinsic importance and interest of the ideas, as well as the places whereHoffmann's thought makes novel contributions to cognate areas. (shrink)
