Concerns about the risks of unmitigated greenhouse gas emissions are growing. At the same time, confidence that international policy agreements will succeed in considerably lowering anthropogenic greenhouse gas emissions is declining. Perhaps as a result, various geoengineering solutions are gaining attention and credibility as a way to manage climate change. Serious consideration is currently being given to proposals to cool the planet through solar-radiation management. Here we analyze how the unique and nontrivial risks of geoengineering strategies pose fundamental questions at (...) the interface between science and ethics. To illustrate the importance of integrated ethical and scientific analysis, we define key open questions and outline a coupled scientific-ethical research agenda to analyze solar-radiation management geoengineering proposals. We identify nine key fields of coupled research including whether solar-radiation management can be tested, how quickly learning could occur, normative decisions embedded in how different climate trajectories are valued, and justice issues regarding distribution of the harms and benefits of geoengineering. To ensure that ethical analyses are coupled with scientific analyses of this form of geoengineering, we advocate that funding agencies recognize the essential nature of this coupled research by establishing an Ethical, Legal, and Social Implications program for solar-radiation management.

In a recent piece, Jon Bebb (2023) has argued that we have no reason to believe, contrary to what is often assumed, that ‘normal’ is ambiguous between a statistical and a normative sense. I argue that his case rests on two false premisses, and that we have very good reasons to believe that ‘normal’ is, in fact, ambiguous in this way. As part of my argument, I will go on to suggest that if ‘normal’ is ambiguous between a statistical and (...) a normative sense, that is because of the deep but seldom recognised connection between regularities and rules. This suggestion, if correct, will in turn help us elucidate three familiar thoughts about normality. (shrink)

This paper examines the remarkable but not much analyzed phenomenon of anti-Cartesianism in the Weimar Republic, which was fueled by philosophers as well as by literary scholars, such as Ernst Robert Curtius. The outright rejection of Descartes needs to be seen within the context of the deep social and political crisis of a defeated Germany between the two World Wars. Rejection of rationality in favour of a perceived deeper German grasp of reality was part of the conservative backlash against the (...) national humiliation. Descartes as both the ‘father of modernity’ and the epitome of French ‘civilisation’ served as the perfect antagonist to what was extolled as the German authentic mode of being. Implanting this anti-Cartesianism into his nationalist elitist philosophical discourse Heidegger amplified it, and under the slogan “German philosophy resists” he channeled it into the national-socialist ideology. In a strange turn of events it was the surge of interest he encountered in post-war France that reestablished Heidegger’s intellectual standing and paved the road to his comeback in Germany around 1950.

I will present and criticise the two theories of truthmaking David Armstrong offers us in Truth and Truthmakers (Armstrong 2004), show to what extent they are incompatible and identify troublemakers for both of them, a notorious – Factualism, the view that the world is a world of states of affairs – and a more recent one – the view that every predication is necessary. Factualism, combined with truthmaker necessitarianism – ‘truthmaking is necessitation’ – leads Armstrong to an all-embracing totality state (...) of affairs that necessitates not only everything that is the case but also everything else – that which is not the case, that which is merely possible or even impossible. All the things so dear to realists – rocks, natural properties, real persons – become mere abstractions from this ontological monster. The view that every predication is necessary does in some sense the opposite: it does away with totality states of affairs and, arguably, also with states of affairs. We have particulars and universals, partially identical and necessarily connected to everything else. Just by the existence of anything, everything is necessitated – the whole world mirrored in every monad. Faced with the choice between these two equally unappealing alternatives, I suggest returning to Armstrong’s more empiricist past: the world is not an all-inclusive One, nor necessitated by every single particular and every single universal, but a plurality of particulars and universals, interconnected by a contingent and internal relation of exemplification. While a close variant, truthmaker essentialism, can perhaps be saved, this means giving up on truthmaker necessitarianism. This, I think, what it takes to steer a clear empiricist course between the Scylla of Spinozist general factness and the Charybdis of a Leibnizian overdose of brute necessities. (shrink)

Some authors have called for increased research on various forms of geoengineering as a means to address global climate change. This paper focuses on the question of whether a particular form of geoengineering, namely deploying sulfate aerosols in the stratosphere to counteract some of the effects of increased greenhouse gas concentrations, would be a just response to climate change. In particular, we examine problems sulfate aerosol geoengineering (SAG) faces in meeting the requirements of distributive, intergenerational, and procedural justice. We argue (...) that SAG faces obstacles to meeting the requirements of all three considered kinds of justice, because its impacts can harm some persons and communities much more than others; it poses serious risks to future generations; and SAG is especially prone to unilateral implementation. While we do not claim that SAG ought not to be implemented, we argue that it is the responsibility of proponents of SAG to recognize and address these ethical obstacles before advocating its implementation.

I reassess the famous arguments of Frank Plumpton Ramsey (1925) against the tenability of the distinction between particulars and universals and discuss their recent elaboration by Fraser MacBride. I argue that Ramsey’s argument is ambiguous between kinds and properties and that his sceptical worries can be resolved once this distinction is taken into account. A crucial role in this dissolution is a notion of what is essential to a property. I close by some epistemological considerations.

It is true of many truths that I do not believe them. It is equally true, however, that I cannot rationally assert of any such truth both that it is true and that I do not believe it. To explain why this is so, I will distinguish absence of belief from disbelief and argue that an assertion of “p, but I do not believe that p” is paradoxical because it is indefensible, i.e. for reasons internal to it unable to convince. (...) A closer examination of the irrationality involved will show that such is the skeptic’s predicament, trying to convince us to bracket knowledge claims we have good grounds to take ourselves to be entitled to. Even if the sceptic cannot be proven wrong, his challenge still demands an answer, if not a treatment. In this paper, I argue that the cure lies in epidemiology rather than epistemology: instead of attacking the sceptic head-long, I commend guerilla tactics, vaccinating our fellow non-sceptics against the sceptical virus. I will not argue that the sceptic is wrong, necessarily wrong or that he cannot be believed, but that he cannot convince. Scepticism requires a leap of faith: something we may justifiably refrain from even on the sceptic’s own standards. (shrink)

God is typically conceived as perfectly good and necessarily so, in two senses: in terms of always performing the best possible act and in terms of having maximal moral worth. Yet any being that freely performs the best act she can must be accorded greater moral worth for any such action than a being that does so necessarily. I conclude that any being that performs the best possible act of necessity cannot also have maximal moral worth, making the concept of (...) God’s perfect goodness incoherent. (shrink)

In her article, "Thinking and Moral Considerations," Hannah Arendt provides a provocative approach to the question of evil by suggesting that banal evil-the most common kind-may arise directly from thoughtlessness. If that is so, thinking may provide an antidote to evil. Learning to think would then offer the individual and society protection against the dangers of thoughtless evil. She further suggests that thinking may clear the way for a form of judging that "when the chips are down" may turn people (...) toward right rather than wrong, beauty rather than ugliness. In this essay I address her claim by noting an example of apparently thoughtless evil, the murder of Duncan by Macbeth, and by showing how this event clarifies Arendt's thesis, including both its weaknesses and its strengths. The use of Macbeth will amount to a sketch of certain features of the play particularly relevant to this ethical issue, followed by an analysis of ways Arendt's thesis connects with the murder of Duncan.

We present a unified diagnosis of three well-known puzzles about proper names, based on a new view of the metaphysics of words and proper names in particular adumbrated by David Kaplan in “Words”. While our solution comes at some metaphysical price, we think it is worth being considered a serious contender and may illustrate the promise of taking more seriously the metaphysical foundations of our semantic theories.

The Theistic Argument from Intentionality (TAI) is a venerable argument for the existence of God from the existence of eternal truths. The argument relies, inter alia, on the premises that (i) truth requires representation, and that (ii) non-derivative representation is a function of, and only of, minds. If propositions are the fundamental bearers of truth and falsity, then these premises entail that propositions (or at least their representational properties) depend on minds. Although it is widely thought that psychologism—the view that (...) the fundamental truth-bearers are mind-dependent—was refuted by Frege, a psychologistic view of propositions has been undergoing a revival. However, this new psychologism suffers from a problem of scarcity—finite minds cannot generate enough thoughts to play the role of fundamental truth-bearers. This objection paves the way for a revised version of the TAI: only an infinite mind can furnish enough thoughts to play the role of propositions. (shrink)

The Council of Europe’s 2008 White Paper on Intercultural Dialogue: ‘living together as equals in dignity’ points to the need for shared values upon which intercultural dialogue might rest. In order, however, to overcome the monologic separateness that threatens community, we must educate ourselves to recognize the dialogism of our humanity and to engage in deep encounters with others with a mature skepticism of all dogmatisms, including our own. In order to aid us in reaching the necessary insight, the author (...) calls upon Bakhtin’s ideas of the dialogism of every utterance and of the unity and heteroglossia of language, Gadamer’s hermeneutical experience that shakes us loose from what we think we know, and Levinas’s description of that transcendent ideal of a dialogue beyond reciprocity. These perspectives break open our certainty that tribalism and individualism are fundamental, placing them instead as secondary phenomena that, though powerful, pronounce neither the initial nor the final word on our life together.

This paper consists of a conversation between a philosopher specialising in ethics and religion and an educational researcher with an interest in cultural studies and contemporary social theory. Dialogic in form, this paper employs an interdisciplinary response to an interdisciplinary project and offers the following components: a dialogic theorizing of the implications for education of a research project on spiritual capital; a continuation of the project of analyzing moral thinking in various cultural and societal settings; a continuation of the project (...) of analyzing political rhetoric (towards an understanding of the polemics of political rhetoric); a reaffirmation of the value of recognizing difference and ambiguity in the global moment.

Peter Ludlow shows how word meanings are much more dynamic than we might have supposed, and explores how they are modulated even during everyday conversation. The resulting view is radical, and has far-reaching consequences for our political and legal discourse, and for enduring puzzles in the foundations of semantics, epistemology, and logic.

Not only the direct physical experiences of deployment can severely harm soldiers’ mental health. Witnessing violations of their moral principles by the enemy, or by their fellow soldiers and superiors, can also have a devastating impact. It can cause soldiers’ moral disorientation, increasing feelings of shame, guilt, or hate, and the need for general answers on questions of right and wrong. Various attempts have been made to keep soldiers mentally sane. One is to provide convincing causes for their deployment, which (...) risks an “end justifies the means” way of thinking. The good cause can provide a moral justification for horrible atrocities. Another method, introduced in the USA, Canada, and Australia, aims to strengthen military personnel’s resistance by promoting and maintaining a happy, optimistic state of mind through the use of positive psychology. Alongside making soldiers “morally fit” for all kinds of situations, the focus could also be on moral recovery and forgiveness. Such a care-based military ethics approach, aimed at mutual understanding and interdependence, could help soldiers handle the emotional impact of moral conflicts. This demands that military units reflect on their organizational culture and rethink oaths and codes of conduct that focus mainly on efficiency and readiness, as well as the soldierly self-image with its seemingly still deeply rooted warrior ethos. Today, resilience and positive psychology in the military is apparently mainly geared to assuring its soldiers’ readiness. An appropriate set of virtues and understanding of virtue ethics that are less centered on self-perfection and autonomy could point to a different form of character-building and lead to a better understanding of others.

The principle of assistance says that the global rich should help the global poor because they are able to do so, and at little cost. The principle of contribution says that the rich should help the poor because the rich are partly to blame for the plight of the poor. This paper explores the relationship between the two principles and offers support for one version of the principle of assistance. The principle of assistance is most plausible, the paper argues, when (...) formulated so as to identify obligations that arise from the needs of particular identifiable members of the global poor, not from impersonal rules or values. Under that formulation, the principle can explain why knowledge of the circumstances faced by individual members of the global poor can have such a marked effect upon the willingness of the global rich to provide help, and can offer a better grounded motivational basis for helping the global poor. These are real advantages, the paper argues, and ones that cannot be matched by stories that focus upon the ways in which the global rich contribute to global poverty. (shrink)

Les Cahiers noirs de Heidegger permettent d’éclairer l’importance chez les épigones de Heidegger des malentendus concernant le langage ainsi que le statut et les objectifs de la philosophie du Maître. Les Cahiers apportent une confirmation de l’utilisation systématique par leur auteur d’une stratégie d’égarement, celle-ci comportant deux aspects majeurs. D’une part, le message heideggérien s’adresse à un « petit nombre » de lecteurs ou auditeurs et non pas aux hommes en général. La pensée de l’Être est en effet conçue comme (...) combat contre la rationalité comme faculté et valeur universelle, la communication devant dès lors se faire intentionnellement ambiguë. D’autre part, suivre la voix de l’Être ne relève pas de l’émancipation humaine mais d’un processus d’« éveil » tribal. (shrink)

Accelerating global climate change drives new climate risks. People around the world are researching, designing, and implementing strategies to manage these risks. Identifying and implementing sound climate risk management strategies poses nontrivial challenges including (a) linking the required disciplines, (b) identifying relevant values and objectives, (c) identifying and quantifying important uncertainties, (d) resolving interactions between decision levers and the system dynamics, (e) quantifying the trade-offs between diverse values under deep and dynamic uncertainties, (f) communicating to inform decisions, and (g) learning (...) from the decision-making needs to inform research design. Here we review these challenges and avenues to overcome them. ▪ People and institutions are confronted with emerging and dynamic climate risks. ▪ Stakeholder values are central to defining the decision problem. ▪ Mission-oriented basic research helps to improve the design of climate risk management strategies.

This chapter provides an introduction to higher-order metaphysics as well as to the contributions to this volume. We discuss five topics, corresponding to the five parts of this volume, and summarize the contributions to each part. First, we motivate the usefulness of higher-order quantification in metaphysics using a number of examples, and discuss the question of how such quantifiers should be interpreted. We provide a brief introduction to the most common forms of higher-order logics used in metaphysics, and indicate a (...) number of questions which can be raised in such systems using logical vocabulary alone. Using a further example, we return to applications of higher-order logics in metaphysics. We also mention key developments in the history of higher-order logic as it pertains to metaphysics. Finally, we mention certain arguments which have been raised against the use of higher-order logic, and some ways of responding to them. (shrink)

War is almost always conducted with various restrictions in the form of rules, rituals, and taboos. Many of the norms that regulate warfare can be found in the tradition of just war. This tradition seeks to provide a middle ground between an unrealistic (at least for politicians) pacifism that does not even allow war in self-defence and a too realistic realism that claims there is no place for ethics in war. The tradition of just war does not have the force (...) of law; it provides, above all, a vocabulary to discuss war in moral terms. At the same time, the tradition does have an impact: it forms the basis of humanitarian law and the Geneva Conventions. Just like with laws, it is recognised here that imperfect adherence to these principles does not necessarily diminish their validity. Most proponents of the tradition believe that the principles of just war, even though some date back centuries, are sufficiently general to be applicable to contemporary conflicts, such as the Russo-Ukrainian War. If we apply the norms of the just war tradition to the current situation in Ukraine, we see that Russia is waging an unjust war in an unjust manner. (shrink)

This entry provides an opinionated overview of central debates surrounding doxastic disagreement, focusing on doxastic states or attitudes such as beliefs and credences. It differentiates between various types of epistemologically significant disagreement based on the agents involved and the source of the disagreement. It also examines and evaluates current accounts of how peers should (rationally) address disagreement and highlights the fundamental principles that support these accounts.

When is it (epistemically) rational to suspend judgment on a proposition? Before addressing this question, one has to clarify what suspension of judgment (in short: suspension) is and establish rationality standards for the attitudes that constitute suspension. Ideally, suspending can be reduced to attitudes for which one already has established rationality standards. This paper distinguishes two kinds of suspension, weak and strong, and offers a reductionist account of suspension based on credence. However, it does not reduce suspension to credence alone (...) but takes a higher-order perspective on credence into account. Other doxastic attitudes such as belief and doubtful belief are also reexamined and defined in the light of this higher-order perspective. (shrink)

This paper examines Margaret Cavendish’s ecological views and argues that, in the Appendix to her final published work, Grounds of Natural Philosophy (1668), Cavendish is defending a normative account of the way that humans ought to interact with their environment. On this basis, we argue that Cavendish is committed to a form of what, for the purposes of this paper, we will call ‘deep ecology,’ where that is understood as the view that humans ought to treat the rest of nature (...) as something of intrinsic value.

To demarcate the limits of experimental knowledge, we probe the limits of what might be called an experiment. By appeal to examples of scientific practice from astrophysics and analogue gravity, we demonstrate that the reliability of knowledge regarding certain phenomena gained from an experiment is not circumscribed by the manipulability or accessibility of the target phenomena. Rather, the limits of experimental knowledge are set by the extent to which strategies for what we call ‘inductive triangulation’ are available: that is, the (...) validation of the mode of inductive reasoning involved in the source-target inference via appeal to one or more distinct and independent modes of inductive reasoning. When such strategies are able to partially mitigate reasonable doubt, we can take a theory regarding the phenomena to be well supported by experiment. When such strategies are able to fully mitigate reasonable doubt, we can take a theory regarding the phenomena to be established by experiment. There are good reasons to expect the next generation of analogue experiments to provide genuine knowledge of unmanipulable and inaccessible phenomena such that the relevant theories can be understood as well supported. This article is part of a discussion meeting issue ‘The next generation of analogue gravity experiments’. (shrink)

Historically, scientific and engineering expertise has been key in shaping research and innovation policies, with benefits presumed to accrue to society more broadly over time. But there is persistent and growing concern about whether and how ethical and societal values are integrated into R&I policies and governance, as we confront public disbelief in science and political suspicion toward evidence-based policy-making. Erosion of such a social contract with science limits the ability of democratic societies to deal with challenges presented by new, (...) disruptive technologies, such as synthetic biology, nanotechnology, genetic engineering, automation and robotics, and artificial intelligence. Many policy efforts have emerged in response to such concerns, one prominent example being Europe's Eighth Framework Programme, Horizon 2020, whose focus on “Responsible Research and Innovation” provides a case study for the translation of such normative perspectives into concrete policy action and implementation. Our analysis of this H2020 RRI approach suggests a lack of consistent integration of elements such as ethics, open access, open innovation, and public engagement. On the basis of our evaluation, we suggest possible pathways for strengthening efforts to deliver R&I policies that deepen mutually beneficial science and society relationships. (shrink)

We argue that recent empirical findings and theoretical models shed new light on the nature of attention. According to the resulting amplification view, attentional phenomena can be unified at the neural level as the consequence of the amplification of certain input signals of attention-independent perceptual computations. This way of identifying the core realizer of attention evades standard criticisms often raised against sub-personal accounts of attention. Moreover, this approach also reframes our thinking about the function of attention by shifting the focus (...) from the function of selection to the function of amplification. (shrink)

Our topic is the theory of topics. My goal is to clarify and evaluate three competing traditions: what I call the way-based approach, the atom-based approach, and the subject-predicate approach. I develop criteria for adequacy using robust linguistic intuitions that feature prominently in the literature. Then I evaluate the extent to which various existing theories satisfy these constraints. I conclude that recent theories due to Parry, Perry, Lewis, and Yablo do not meet the constraints in total. I then introduce the (...) issue-based theory—a novel and natural entry in the atom-based tradition that meets our constraints. In a coda, I categorize a recent theory from Fine as atom-based, and contrast it to the issue-based theory, concluding that they are evenly matched, relative to our main criteria of adequacy. I offer tentative reasons to nevertheless favour the issue-based theory. (shrink)

We propose a solution to the problem of logical omniscience in what we take to be its fundamental version: as concerning arbitrary agents and the knowledge attitude per se. Our logic of knowledge is a spin-off from a general theory of thick content, whereby the content of a sentence has two components: an intension, taking care of truth conditions; and a topic, taking care of subject matter. We present a list of plausible logical validities and invalidities for the logic of (...) knowledge per se for arbitrary agents, and isolate three explanatory factors for them: the topic-sensitivity of content; the fragmentation of knowledge states; the defeasibility of knowledge acquisition. We then present a novel dynamic epistemic logic that yields precisely the desired validities and invalidities, for which we provide expressivity and completeness results. We contrast this with related systems and address possible objections. (shrink)

William Molyneux was born in Dublin, studied in Trinity College Dublin, and was a founding member of the Dublin Philosophical Society (DPS), Ireland’s counterpart to the Royal Society in London. He was a central figure in the Irish intellectual milieu during the Early Modern period and – along with George Berkeley and Edmund Burke – is one of the best-known thinkers to have come out of that context and out of Irish thought more generally. In 1688, when Molyneux wrote the (...) letter to Locke in which he posed the now famous question about a man born blind made to see, he was an active member of the DPS and was on familiar terms with several other key figures in Irish philosophy at the time. For the most part, Irish thinkers in the seventeenth and eighteenth centuries answered “no” to Molyneux’s question of whether a blind man made to see could distinguish, by sight alone, between a cube and a sphere.

This article gives an overview over different principles of epistemic closure, their attractions and their problems.

According to the Acceptance Principle, a person is entitled to accept a proposition that is presented as true (asserted) and that is intelligible to him or her, unless there are stronger reasons not to. Burge assumes this Principle and then argues that it has an apriori justification, basis or rationale. This paper expounds Burge's teleological reliability framework and the details of his a priori justification for the Principle. It then raises three significant doubts.

You don't say much about who you are teaching, or what subject you teach, but you do seem to see a need to justify what you are doing. Perhaps you're teaching underprivileged children, opening their minds to possibilities that might otherwise never have occurred to them.

If you're doing something like (...) this, then stick with it. Giving money isn't the only way to make a difference. (shrink)

What does ‘Smith knows that it might be raining’ mean? Expressivism here faces a challenge, as its basic forms entail a pernicious type of transparency, according to which ‘Smith knows that it might be raining’ is equivalent to ‘it is consistent with everything that Smith knows that it is raining’ or ‘Smith doesn’t know that it isn’t raining’. Pernicious transparency has direct counterexamples and undermines vanilla principles of epistemic logic, such as that knowledge entails true belief and that something can (...) be true without one knowing it might be. I re-frame the challenge in precise terms and propose a novel expressivist formal semantics that meets it by exploiting (i) the topic-sensitivity and fragmentation of knowledge and belief states and (ii) the apparent context-sensitivity of epistemic modality. The resulting form of assertibility semantics advances the state of the art for state-based bilateral semantics by combining attitude reports with context-sensitive modal claims, while evading various objectionable features. In appendices, I compare the proposed system to Beddor and Goldstein’s ‘safety semantics’ and discuss its analysis of a modal Gettier case due to Moss. (shrink)

We explore some possibilities for developing epistemic logic using truthmaker semantics. We identify three possible targets of analysis for the epistemic logician. We then list some candidate epistemic principles and review the arguments that render some controversial. We then present the classic Hintikkan approach to epistemic logic and note—as per the ‘problem of logical omniscience’—that it validates all of the aforementioned principles, controversial or otherwise. We then lay out a truthmaker framework in the style of Kit Fine and present six (...) different ways of extending this semantics with a conditional knowledge operator, drawing on notions of implication and content that are prominent in Fine’s work. We demonstrate that different logics are thereby generated, bearing on the aforementioned epistemic principles. Finally, we offer preliminary observations about the prospects for each logic. (shrink)
