Fixpoint semantics are provided for ambiguity blocking and propagating variants of Nute's defeasible logic. The semantics are based upon the well-founded semantics for logic programs. It is shown that the logics are sound with respect to their counterpart semantics and complete for locally finite theories. Unlike some other nonmonotonic reasoning formalisms such as Reiter's default logic, the two defeasible logics are directly skeptical and so reject floating conclusions. For defeasible theories with transitive priorities on defeasible rules, the logics are shown (...) to satisfy versions of Cut and Cautious Monotony. For theories with either conflict sets closed under strict rules or strict rules closed under transposition, a form of Consistency Preservation is shown to hold. The differences between the two logics and other variants of defeasible logic—specifically those presented by Billington, Antoniou, Governatori, and Maher—are discussed. (shrink)

This paper reports completeness results for dyadic deontic logics in the tradition of Hansson’s systems. There are two ways to understand the core notion of best antecedent-worlds, which underpins such systems. One is in terms of maximality, and the other in terms of optimality. Depending on the choice being made, one gets different evaluation rules for the deontic modalities, but also different versions of the so-called limit assumption. Four of them are disentangled, and compared. The main observation of this paper (...) is that, even in the partial order case, the contrast between maximality and optimality is not as significant as one could expect, because the logic remains the same whatever notion of best is used. This is established by showing that, given analogous properties for the betterness relation, the same system is sound and complete with respect to its intended modelling. The chief result of this paper concerns Åqvist’s system F supplemented with the principle of cautious monotony. It is established that, under the maximality rule, F + is sound and complete with respect to the class of models in which the betterness relation is required be reflexive and smooth . From this, a number of spin-off results are obtained. First and foremost, it is shown that a similar determination result holds for optimality; that is, under the optimality rule, F + is also sound and complete with respect to the class of models in which the betterness relation is reflexive and smooth . Other spin-off results concern classes of models in which further constraints are placed on the betterness relation, like totalness and transitivity. (shrink)

The hum of a ceiling fan, the mechanical grind of an escalator, Pilates repetitions, treadmills and stationary bicycles, waiting room Muzak and its tedious refrain: such experiences of monotony are ubiquitous. Continuous, unchanging, regular, repetitious: truly predictable, the sameness of monotony is particularly unbearable for it does not stop. Its tedium is an expression of its unbending relationship to time, an excessive duration. Monotony never wavers, never falters, never surprises. Monotony cannot seduce; there is no attraction (...) of fleeting adventure or freedom in monotony, which is absolute prolongation without hesitation or variation, entirely anticipatable.Monotony is often a cause of boredom, yet it is...

Boredom is an affective experience that can involve pervasive feelings of meaninglessness, emptiness, restlessness, frustration, weariness and indifference, as well as the slowing down of time. An increasing focus of research in many disciplines, interest in boredom has been intensified by the recent Covid-19 pandemic, where social distancing measures have induced both a widespread loss of meaning and a significant disturbance of temporal experience. This article explores the philosophical significance of this aversive experience of ‘pandemic boredom.’ Using Heidegger’s work as (...) a unique vantage point, this article draws on survey data collected by researchers in an ongoing project titled ‘Experiences of Social Distancing During the Covid-19 Pandemic’ to give an original phenomenological interpretation of the meaninglessness and monotony of pandemic boredom. On a Heideggerian interpretation, pandemic boredom involves either a situative confrontation with relative meaninglessness that upholds our absorption in the everyday world, or an existential confrontation with absolute meaninglessness that forces us to take up the question of our existence. Arguing that boredom during the pandemic makes this distinction difficult to sustain, I consider some of the ways in which pandemic boredom might be seen to expose and then exceed the distinctive methodological limitations of Heidegger’s philosophical interpretation of boredom.

This article draws upon discursive psychology to explore the organization of public accountability in accounting for an alleged conflict of interest in journalism. The analysis focuses on the published record of an interview given by the editorial director of one of the major Romanian daily newspapers on the issue of an assumed conflict of interest involving a senior editor of the same newspaper. The analysis shows how a moral order is constituted by the use of various discursive resources: role and (...) professional incumbency discourse, disposition avowals and doing being fair/ democratic. This is a moral order where adherence to personal ethical principles, professional incumbencies and responsibilities are practically managed in dialogue and publicly displayed. Acting in-role, reporting a general disposition to engage in moral courses of action and making reference to the values of citizenship and democracy are all publicly available discursive resources used in this context to express a cautious moral judgement bounded and constrained by both personal and professional accountability perspectives.

Sustainable development is a common goal in the public sector but may be difficult to implement due to epistemic uncertainties and the long time frames required. This paper proposes that some of these problems can be solved by formulating cautious utopias, entailing a relationship between means and goals differing from both utopian and realistic goal-setting. Cautiously utopian goals are believed, but not certain, to be achievable and to remain desirable, but are open to future adjustments due to changing desires (...) and/or factual circumstances. Quality criteria for such goals are suggested. (shrink)

In this thesis, the framework within which long-term goals are set and subsequently achieved or approached is analyzed. Sustainable development and climate change are areas in which goals have tobe set despite uncertainties. The analysis is divided into the normative motivations for setting such goals, what forms of goals could be set given the empirical and normative uncertainties, and how tomanage doubts regarding achievability or values after a goal has been set. Paper I discusses a set of questions that moral (...) theories intended to guide goal-setting should respond to. It is often claimed that existent normative theories provide only modest guidance regarding climate change, and consequently have to be revised or supplemented. Two such suggested revisions or supplements are analyzed in order to determine whether they provide such guidance. Paper II applies the deep ecological framework to survey the extent to which it can be utilized to discuss issues concerning the management of climate change. It is suggested that the deep ecological framework can provide guidance by establishing a normative framework and an analysis of how the overarching values and principles can be specified to be relevant for actions. Paper III is focused on normative political theory, and explicates the two dimensions of empirical and normative uncertainty. By applying recent discussions in normative political theory on ideal/non-ideal theory, political realism, and the relation between normative demands and empirical constraints,strategies for managing the proposed goals are suggested. Paper IV suggests a form of goal that incorporates uncertainties. Cautious utopias allow greater uncertainty than realistic goals,but not to the same extent as utopian goals. Such goals have a performance-enhancing function. A definition and quality criteria for such goals are proposed. Paper V considers whether a goal that is becoming all the more unlikely to be achievable should be reconsidered. The paper focuses on the two degrees Celsius target, and asks whether it could still be a sensible goal to aspire to. By applying the principle that ‘ought’ implies ‘can’, the role of such obligations is investigated. Paper VI surveys how to treat circumstances in which an already set goal should be reconsidered and possibly revised, and what would evoke doubt in the belief upon which those goals have been set.Two situations are analyzed: a problematic or surprising event occurs, upsetting confidence in one’s relevant beliefs, or respectable but dissenting views are voiced concerning one’s means and/or values. It is suggested that the validity of doubt has to be considered, in addition to the level in a goal-means hierarchy towards which doubt is raised. (shrink)

This paper introduces and studies a notion of cautious distributed belief. Different from the standard distributed belief, the cautious distributed belief of a group is inconsistent only when all group members are individually inconsistent. The paper presents basic results about cautious distributed belief, investigates whether it preserves properties of individual belief, and compares it with standard distributed belief. Although both notions are equivalent in the class of reflexive models, this is not the case in general. While we (...) argue that an understanding of the concept of cautious distributed belief from first principles is important, cautious distributed belief can be expressed using standard distrbuted belief and we show that the propositional language extended only with cautious distributed belief is in fact strictly less expressive than the propositional language extended only with standard distributed belief. We, finally, identify a small extension of the language making the former as expressive as the latter. (shrink)

Psychobiography has been a topical area and an applied research specialty in psychology since Freud’s influential psychoanalytic psychobiography of Leonardo da Vinci. Throughout the last century, psychobiographers have emphasized the importance of anchoring interpretations of life histories in established psychological theories and rigorous historiographic research methods. One topical area receiving less attention in psychobiography is the critical relationship between the psychobiographer and her or his subject as it relates to the process of psychobiographical writing. The present article explores the phenomenology (...) and challenges of this relationship in order to ultimately propose practical strategies for navigating countertransference issues throughout the subject selection, research and publication phases of psychobiography. Freud’s psychobiography of Leonardo da Vinci is used as a model of the stages of psychobiography, the evolution of the psychobiographer-subject relationship, and the challenges of countertransference.

The global relation between logical empiricism and American pragmatism is one of the more difficult problems in history of philosophy. In this paper I’d like to take a local perspective and concentrate on the details that concern the vicissitudes of a philosopher who played an important role in the encounter of logical empiricism and American pragmatism, namely, Ernest Nagel. In this paper, I want to explore some aspects of Nagel’s changing attitude towards the then „new“ logical-empiricist philosophy. In the beginning (...) Nagel welcomed logical empiricism whole-heartedly. This early enthusiasm did not last. At the end of his philosophical career Nagel’s early positive attitude towards logical empiricism shown in the 1930s had been replaced by a much more reserved one. Nagel’s growing dissatisfaction with the Carnapian version of logical empiricist philosophy was clearly expressed in Nagel’s criticism of Carnap’s inductive logic and more generally in his last book Teleology Revisited and Other Essays on History and Philosophy of Science. There he critized harshly Carnap’s philosophy of science in general as ahistoric and non-pragmatist. One of the distinctive features of Nagel’s philosophy of science is the emphasis that he put on the role of history of science for philosophy of science. A compelling evidence for this attitude are his works on the history and philosophy of geometry and algebra One may say that Carnap and Nagel represented opposed possibilities of how the profession of a philosopher of science could be understood: Carnap as a „conceptual engineer“ was engaged in the task of inventing the conceptual tools for a better theoretical understanding of science, while Nagel was to be considered more as a „public intellectual“ engaged in the project of realizing a more rational and enlightened society.

We adopt the largest consistent set defined by Chwe (1994; J. Econ. Theory 63: 299–325) to predict which coalition structures are possibly stable when players are farsighted. We also introduce a refinement, the largest cautious consistent set, based on the assumption that players are cautious. For games with positive spillovers, many coalition structures may belong to the largest consistent set. The grand coalition, which is the efficient coalition structure, always belongs to the largest consistent set and is the (...) unique one to belong to the largest cautious consistent set. (shrink)

May expresses optimism about the source, content, and consequences of moral judgments. However, even if we are optimistic about their source (i.e., reasoning), some pessimism is warranted about their content, and therefore their consequences. Good reasoners can attain moral knowledge, but evidence suggests that most people are not good reasoners, which implies that most people do not attain moral knowledge.

The AGM success postulates for belief expansions and revisions have been widely criticized. This has resulted in the development of a number of non-prioritized belief change theories that violate these postulates. It is shown that we must also discard the monotony postulate for belief expansions if we abandon the success postulates. Non-prioritized belief change theories should instead fulfill a weaker postulate, which we call Conditional Monotony.

Annette Baier was the dean of contemporary Hume studies and one of the most insightful and influential philosophers writing on Hume. Since the late 1970s, her writings and the example of her distinctive mode of scholarship have inspired generations of scholars to look with fresh eyes at Hume's work. The special turn of her philosophical mind and personal style of writing are especially well-suited to uncover, appreciate, and effectively communicate the rich, nuanced, and humane dimensions of Hume's moral philosophy. Her (...) masterpiece, A Progress of Sentiments (Cambridge, MA: Harvard University Press, 1991), for example, taught us that Hume's moral psychology underwrites his moral and social philosophy.

This paper introduces a generalization of Reiter’s notion of “extension” for default logic. The main difference from the original version mainly lies in the way conflicts among defaults are handled: in particular, this notion of “general extension” allows defaults not explicitly triggered to pre-empt other defaults. A consequence of the adoption of such a notion of extension is that the collection of all the general extensions of a default theory turns out to have a nontrivial algebraic structure. This fact has (...) two major technical fall-outs: first, it turns out that every default theory has a general extension; second, general extensions allow one to define a well-behaved, skeptical relation of defeasible consequence for default theories, satisfying the principles of Reflexivity, Cut, and Cautious Monotonicity formulated by D. Gabbay. (shrink)

This article start from two opposing intuitions in the environmental duties debate. On the one hand, if our lifestyle causes environmental harm, then we have a duty to reduce that impact through lifestyle changes. On the other hand, many people share the intuition that environmental duties cannot demand to alter our lifestyle radically for environmental reasons. These two intuitions underlie the current dualism in the environmental duties debate: those arguing for lifestyle changes and those arguing that our duties are limited (...) to promoting just environmental institutions. The paper has two goals: first, to grasp the underlying reasons for the two intuitions, and, second, to provide a proposal that integrates both intuitions. The paper consists of two main parts. The first part examines the ‘our-duties-should-be-limited’ intuition. Two interpretations are discussed, one under the title ‘what I do make no difference’, dealing with causality and collective action, and one under the title ‘my duty cannot be to change my lifestyle completely’, which discusses demandingness, fairness and value conflict. The second part shows how the ‘lifestyle-matters’ intuition can still play an important role. This part consists of two sections, one on ‘how to make a difference’, which deals with the idea of a cooperative ethos, and the other with ‘why lifestyle matters’, discussing expressive rationality and integrity. These ideas allow giving an important place to lifestyle duties, while avoiding the possible counterproductive effect of a private duties account. (shrink)

This note is on cautious cut elimination for one of Veitman's might logics. Syntactically, the logic is presented as an extension of a sequent system for classical proposition logic . I show that this extension preserves the completeness and decidability of CPL. The proof has cautious cut elimination as a corollary. I also give a rather general syntactic proof of cautious cut elimination. It states that any ‘base’ logic which has a reflexive, monotone consequence relation that allows (...) cautious cut to be eliminated preserves cautious cut elimination when extended to a might logic.

In this paper, I develop what I call, following Steven Shaviro, Merleau-Ponty’s “cautious anthropomorphism.” Rather than defending Merleau-Ponty against the accusation of anthropomorphism, I show the role this anthropomorphism plays in Merleau-Ponty’s critique of the Cartesian-Sartrian ontology of the object. If the thing is always “clothed with human characteristics,” as Merleau-Ponty says in the Causeries, it is not so that it can be reduced to a powerless object that can easily be assimilated but rather to ensure its own resistance (...) or adversity – and even, paradoxically, its inhumanity. After developing Sartre’s and Merleau-Ponty’s views of things, focusing on their respective reading of Ponge in “Man and Things” and the Causeries, I put Merleau-Ponty in conversation with Jeffrey Cohen’s book Stone to push for a non-humanistic reading of Merleau-Ponty’s anthropomorphism.

Shamans, healers, and doctors have always known that patients may improve even if no real therapy is administered. In the Charmides, Plato noted that to soothe a headache, one needed "a kind of leaf, which required to be accompanied by a charm, and if a person would repeat the charm at the same time he used the cure, he would be made whole; but that without the charm would be of no avail". Similarly, more than two millennia later, Thomas Jefferson (...) observed, "One of the most successful physicians I have even known has assured me that he used more bread pills, drops of colored water, and powder of hickory ashes, than of all other medication put together"; Jefferson famously labeled this...

Should fear guide our actions and governments’ political decisions? A leitmotiv of common sense is that emotions are tricky, they blur our rational capacity of estimating utilities in order to plan action and thus they should be banned from any account of our rational expectations. In this paper I argue that an “heuristic of fear” is the appropriate attitude to adopt in order to cope with extreme risks. I thus defend the Precautionary Principle against the criticism put forward by Cass (...) Sunstein and other authors on the basis of a new analysis of extreme risks or “ruin-problems”. (shrink)

This paper critiques the version of the argument that the regulation of hateful speech by the state undermines its democratic legitimacy made by Ronald Dworkin and James Weinstein. It argues that in some cases the harmful effects of hateful speech on the democratic process outweigh those of restriction. It does not challenge the central premise of the Legitimacy Argument, that a wide-ranging right to freedom of expression is an essential political right in a liberal democracy. Instead, it uses ideal and (...) nonideal theory as a framework for judgements about the regulation of hate speech. The mistake underpinning the Legitimacy Argument is that it assumes that other conditions pervade that make an ideal democratic procedure possible when they do not. In reality the state can be put in a position where, whatever course of action it takes with regard to the regulation or non-regulation of hate speech, some citizens will not be able to participate fully in political deliberation. Under such conditions there remain strong pro tanto reasons not to regulate hate speech on democratic grounds, but they are not all-things-considered reasons, and there are also pro tanto reasons to regulate hate speech that might outweigh them in some cases. This leads to the cautious conclusion that while there might be a normative justification for the regulation of hate speech in individual instances, the debate is best understood as one between competing pro tanto reasons, and must be approached on a case-by-case basis.
