abstract Even though much research has been devoted to studies of safety, the concept of safety is in itself under‐theorised, especially concerning its relation to epistemic uncertainty. In this paper we propose a conceptual analysis of safety. The paper explores the distinc‐tion between absolute and relative safety, as well as that between objective and subjective safety. Four potential dimensions of safety are discussed, viz. harm, probability, epistemic uncertainty, and control. The first three of these are used in the proposed definition (...) of safety, whereas it is argued that control should not be included in a reasonable definition of safety. It is shown that strictly speaking, an objective safety concept is not attainable. Instead, an intersubjective concept is proposed that brings us as close as possible to an objective concept.

Empathy is an integral aspect of human existence. Without at least a basic ability to access others’ affective life, social interactions would be well-nigh impossible. Yet, recent studies seem to show that the means we have acquired to access others’ emotional life no longer function well in what has become our everyday business – technologically mediated interactions in digital spaces. If this is correct, there are two important questions: (1) What makes empathy for frequent internet users so difficult? and (2) (...) What can we do to alleviate the negative consequences? Correspondingly, the aim of this paper is twofold. First, we identify structural differences between offline and technologically mediated interactions that can explain why digital empathy is harder to achieve. Second, drawing on the literature on ‘situated affectivity,’ we consider the idea of modifying digital spaces in ways specifically designed to ‘scaffold’ empathy where our evolved mechanisms fail. Section 2 argues that empathy is requires interpreting the behavior of embodied subjects. Section 3 identifies three factors that are crucial for this interpretative endeavor: the empathizer’s affective repertoire, their perceptual input, and their background knowledge. Section 4 argues that technologically mediated interactions differ from face-to-face interactions with regard to these factors in ways which render our evolved empathy mechanisms less effective in the digital world. Section 5 introduces the idea that situational factors can serve as ‘empathic scaffolds,’ i.e., as ‘tools’ that can ‘shape’ people’s empathic reactions. Section 6 wraps up the main line of reasoning, responds to objections and invites further scholarship. (shrink)

Kernel contraction is a natural nonrelational generalization of safe contraction. All partial meet contractions are kernel contractions, but the converse relationship does not hold. Kernel contraction is axiomatically characterized. It is shown to be better suited than partial meet contraction for formal treatments of iterated belief change.

What purpose can be served by empirically unsubstantiated speculation in ethics? In answering that question, we need to distinguish between the major branches of ethics. In foundational moral philosophy, the use of speculative examples is warranted to the extent that ethical principles and theories are assumed to be applicable even under the extreme circumstances referred to in these examples. Such an assumption is in need of justification, and it cannot just be taken for granted. In applied ethics, the use of (...) unrealistic scenarios is more difficult to justify. It can be positively harmful if it diverts our attention from more urgent issues. Neuroethics is one of the areas of applied ethics where speculative scenarios have taken up much of the attention that could instead have been devoted to problems that are relevant for the treatment and care of patients. Speculative ethics has often been defended with mere possibility arguments that may at first hand seem difficult to refute. It is shown with examples how such claims can be defeated with a combination of science and argumentation analysis. (shrink)

Multiple contraction (simultaneous contraction by several sentences) and iterated contraction are investigated in the framework of specified meet contraction (s.m.c.) that is extended for this purpose. Multiple contraction is axiomatized, and so is finitely multiple contraction (contraction by a finite set of sentences). Two ways to reduce finitely multiple contraction to contraction by single sentences are introduced. The reduced operations are axiomatically characterized and their properties are investigated. Furthermore, it is shown how iterated contraction can be reduced to single-step, single-sentence (...) contraction. However, in this framework the outcome of iterated contraction depends unavoidably on the order in which the inputs are received. This order-dependence makes it impossible to treat two inputs on an equal footing. Therefore it is often preferable to perform changes involving several pieces of information as multiple rather than iterated change. (shrink)

The outcome set of a belief change operator is the set of outcomes that can be obtained with it. Axiomatic characterizations are reported for the outcome sets of the standard AGM contraction operators and eight types of base-generated contraction. These results throw new light on the properties of some of these operators.

Abstract: This article offers a perspective on the role of philosophy in relation to other academic disciplines and to society in general. Among the issues treated are the delimitation of philosophy, whether it is a science, its role in the community of knowledge disciplines, its losses of subject matter to other disciplines, how it is influenced by social changes and by progress in other disciplines, and its role in interdisciplinary work. It is concluded that philosophy has an important mission in (...) promoting clarity, precision, and open-mindedness in academic research and in society at large. (shrink)

discussions of risk contain logical and argumentative fallacies that are specific to the subject-matter. Ten such fallacies are identified, that can commonly be found in public debates on risk. They are named as follows: the sheer size fallacy, the converse sheer size fallacy, the fallacy of naturalness, the ostrich's fallacy, the proof-seeking fallacy, the delay fallacy, the technocratic fallacy, the consensus fallacy, the fallacy of pricing, and the infallability fallacy.

Modern belief revision theory is based to a large extent on partial meet contraction that was introduced in the seminal article by Carlos Alchourrón, Peter Gärdenfors, and David Makinson that appeared in 1985. In the same year, Alchourrón and Makinson published a significantly different approach to the same problem, called safe contraction. Since then, safe contraction has received much less attention than partial meet contraction. The present paper summarizes the current state of knowledge on safe contraction, provides some new results (...) and offers a list of unsolved problems that are in need of investigation. (shrink)

Generalizations of partial meet contraction are introduced that start out from the observation that only some of the logically closed subsets of the original belief set are at all viable as contraction outcomes. Belief contraction should proceed by selection among these viable options. Several contraction operators that are based on such selection mechanisms are introduced and then axiomatically characterized. These constructions are more general than the belief base approach. It is shown that partial meet contraction is exactly characterized by adding (...) to one of these constructions the condition that all logically closed subsets of the belief set can be obtained as the outcome of a single (multiple) contraction. Examples are provided showing the counter-intuitive consequences of that condition, thus confirming the credibility of the proposed generalization of the AGM framework. (shrink)

Some of the major problems in radiation protection are closely connected to issues that have a long, independent tradition in moral philosophy. This contribution focuses on two of these issues. One is the relationship between the protection of individuals and optimisation on the collective level, and the other is the relative valuation of future versus immediate damage. Some of the intellectual tools that have been developed by philosophers can be useful in radiation protection. On the other hand, philosophers have much (...) to learn from radiation protectors, not least when it comes to finding pragmatic solutions to problems that may be intractable in principle. (shrink)

ABSTRACT John Rawls proposed two criteria for the delimitation of acceptable inequalities. The universal gain principle requires inequalities to be beneficial for all, and the difference principle requires them to be beneficial for the least advantaged. These principles are commonly believed to have originated in Rawls’s work, but they were both clearly expressed in the writings of Nicolas de Condorcet. Contrary to Rawls, Condorcet did not imbed them in the framework of a social contract, but instead sought their foundations in (...) natural rights. Whereas Rawls recommends us to find out what social arrangements rational reasoners would choose in a hypothetical pre-social situation, Condorcet proposes that we ask the underprivileged in our society whether or not they consider themselves to benefit from the prevailing social and economic inequalities. Thus, Condorcet’s original version of the difference principle puts social inequalities to a different test than its latter-day, hypothetical version. (shrink)

Two types of measures of probabilistic uncertainty are introduced and investigated. Dispersion measures report how diffused the agent’s second-order probability distribution is over the range of first-order probabilities. Robustness measures reflect the extent to which the agent’s assessment of the prior (objective) probability of an event is perturbed by information about whether or not the event actually took place. The properties of both types of measures are investigated. The most obvious type of robustness measure is shown to coincide with one (...) of the major candidates for a dispersion measure, the mean square deviation measure. (shrink)

In order to reduce the death toll of road traffic it is necessary to focus on how vehicles and roads can be improved. Like other dangerous machines, motor vehicles should be equipped with safety devices that prevent mistakes by the operator from leading to serious consequences. Speed limiters that prevent driving at illegal speeds would save many lives, and so would alcohol interlocks. Meshi Ori's proposal that most cars should be replaced by motorcycles would not lead to the moral improvement (...) that he hopes for. We need motor vehicles with better, not worse, protection of the driver and passengers than the cars presently in use. (shrink)

J.S. Mill’s advocacy of liberty was based only in part on his harm principle. He also endorsed two other principles that considerably extend the scope of liberty: first, a principle of individual liberty that is based on the value of positive freedom and of developing individuality, and second, a principle of free trade or economic freedom that is based on the value of economic efficiency. An analysis is offered of how these three principles are combined in Mill’s account of liberty (...) and how they connect with his antipaternalism. It is proposed that his appeal in On Liberty to positive freedom and the development of individuality provides a uniting principle that makes his view on liberty cohere with his utilitarianism.

Den moralfilosofiska traditionen har sina begränsningar. De frågor som stått i centrum för den moralfilosofiska diskussionen har ofta varit helt andra än de som människor i det praktiska livet har uppfattat som centrala moraliska problem. En viktig begränsning är att moralfilosofin, liksom beslutsteorin, nästan uteslutande har handlat om hur man hanterar välavgränsade problem där handlingsalternativen är givna. I det verkliga livet löser vi ofta moraliska problem genom att finna på nya handlingsalternativ, som inte fanns med från början.1 En annan begränsning (...) är att moralfilosofin till allra största delen har handlat om situationer där konsekvensen av de olika handlingsalternativen är välkänd. I det praktiska livet är det annorlunda. Vi vet sällan med säkerhet vad som kommer att bli följden av de olika alternativ som vi väljer mellan. Man kan också uttrycka detta så att moralfilosofin i huvudsak rör sig i en tänkt deterministisk värld, där man inte behöver räkna med någon slump. Detta är aningen märkligt mot bakgrund av det oerhörda genomslag som sannolikhetstänkande och på senare år även kaos har fått inom andra vetenskapsområden. Det finns naturligtvis förklaringar till detta moralfilosofins kvardröjande i en äldre världsbild. Redan i det deterministiska fallet uppstår svårhanterliga problem som man gärna ger sin odelade uppmärksamhet. Dessutom finns det en särskild disciplin, beslutsteorin, som behandlar beslut under risk och osäkerhet. Man har i allmänhet tänkt sig ett slags arbetsfördelning, där problemen med risk och osäkerhet utelämnas i moralfilosofin för att i stället hanteras inom beslutsteorin med rena rationalitetsprinciper (dvs. utan att moraliska principer är inblandade). Enligt min mening är denna arbetsfördelning inte hållbar. Betrakta t ex osäkerheten om hur klimatet kommer att förändras med nuvarande utsläppstrender för växthusgaser. Denna osäkerhet ger upphov inte enbart till ett problem om rationellt beslutsfattande utan också till moraliska problem.. (shrink)

Indicative conditionals with present tense antecedents can have ‘shifted’ readings that are unexpected given the semantic behavior of the tenses outside of conditionals. In this paper, we compare two accounts of this phenomenon due to Kaufmann (J Semant 22(3):231–280, 2005) and Schulz (SALT XVIII, pp. 694–710, 2008), by reconstructing them in the framework of branching time. We then propose a novel account of indicative conditionals based on the branching time semantics suggested in Rumberg (J Logic Lang Inf 25(1):77–108, 2016), viz. (...) transition semantics. We show that not only is the account of ‘shifted’ readings with present tense antecedents within this semantics very natural, but it also is empirically superior to its rivals in some respects.

The prescriptive has both an objective and a subjective interpretation. In the objective sense, what one ought to do depends on what is actually true. In the subjective sense it depends on what one believes to be true. Ordinary usage seems to vacillate between these two interpretations. An example (the indecisive terrorist) is used to show that a subjective ought statement can have a determinate truth-value in situations where the corresponding objective ought statement has no truth-value, not even an unknowable (...) one. Therefore the subjective ought is not definable in terms of the objective ought. However, definability in the other direction is not excluded by this argument. (shrink)

I väntan på den engelska Festschriften, den definitiva biografin eller de självförhärligande memoarerna kommer här för första gången en samling porträtt av den internationellt mest uppmärksammade svenska statsvetaren, den kontroversielle samhällsdebattören Bo Rothstein. Få samhällsforskare har med sådan intensitet tagit universitetens tredje uppgift till intäkt för att ifrågasätta gängse uppfattningar om sakernas tillstånd i riket. Många är de läsare, tittare eller åhörare som knappast kunnat undgå att beröras av hans synpunkter på allt från metoo till tiggeri, något färre är nog (...) de som på allvar tagit del av hans forskningsresultat om korruption och statsförvaltning. I denna bok tecknar ett tjugotal svenska forskare, författare och vänner sin bild av forskaren, debattören och livsnjutaren Bo Rothstein."--Back cover. (shrink)

A money-pump is a thought experiment involving a person whose preferences form a circle. Repeatedly, she pays some money to go from one alternative to another that she likes better. When she has paid her way around the full circle she is back at the starting-point, but with less money. Money-pumps have been used to show that certain preference patterns are irrational since they make a person exploitable. Formal tools can be used to analyze money-pumps in a precise manner, distinguish (...) between different types of money-pumps, and investigate decision strategies to avoid their pernicious effects. Although money-pumps are rather contrived constructions, these investigations have practical relevance since there seem to be decision situations in the real world with the same structure. (shrink)

Preferences and choices have central roles in moral philosophy, economics, and the decision sciences in general. In a formal language we can express and explore the properties of preferences, choices, and their interrelations in a precise way, and uncover connections that are inaccessible without formal tools. In this chapter, the plausibility of different such properties is discussed, and it is shown how close attention to the logical details can help dissolve some apparent paradoxes in informal and semi-formal treatments.

The volume analyses and develops David Makinson’s efforts to make classical logic useful outside its most obvious application areas. The book contains chapters that analyse, appraise, or reshape Makinson’s work and chapters that develop themes emerging from his contributions. These are grouped into major areas to which Makinsons has made highly influential contributions and the volume in its entirety is divided into four sections, each devoted to a particular area of logic: belief change, uncertain reasoning, normative systems and the resources (...) of classical logic. Among the contributions included in the volume, one chapter focuses on the “inferential preferential method”, i.e. the combined use of classical logic and mechanisms of preference and choice and provides examples from Makinson’s work in non-monotonic and defeasible reasoning and belief revision. One chapter offers a short autobiography by Makinson which details his discovery of modern logic, his travels across continents and reveals his intellectual encounters and inspirations. The chapter also contains an unusually explicit statement on his views on the role of logic in philosophy. (shrink)

In order to shorten queues to healthcare, the Swedish government has introduced a yearly “queue billion” that is paid out to the county councils in proportion to how successful they are in reducing queues. However, only the queues for first visits are covered. Evidence has accumulated that queues for return visits have become longer. This affects the chronically and severely ill. Swedish physicians, and the Swedish Medical Association, have strongly criticized the queue billion and have claimed that it conflicts with (...) medical ethics. Instead they demand that their professional judgments on priority setting and medical urgency be respected. This discussion provides an interesting illustration of some of the limitations of new public management and also more generally of the complicated relationships between medical ethics and public policy.
