Recent studies have highlighted the relevance of sleep for procrastination at work. Procrastination at work is defined as the irrational delay of the initiation or completion of work-related activities. In line with recent studies, we offer a self-regulation perspective on procrastination. We argue that procrastination is an outcome of depleted self-regulatory resources and that the restoration of self-regulatory resources during high-quality sleep at night would prevent procrastination.AimsIn an attempt to further develop this line of research, the current study aimed to (...) achieve a broader understanding of the relevance of sleep and circadian rhythm for procrastination. Therefore, we explored the effect of sleep quality on procrastination for different chronotypes. We also considered the shift to daylight saving time as a phenomenon that aggravates circadian misalignment and thereby later chronotypes' dependence on high-quality sleep. Specifically, we hypothesized that compared to employees with an earlier chronotype, employees with a later chronotype are more dependent on good sleep at night to prevent procrastination the next day. This effect would be especially pronounced after the shift to daylight saving time.MethodsFor this repeated-measures study, participants were 101 full-time employees. They completed a general questionnaire and day-specific questionnaires on the Monday before and the Monday following the shift to daylight saving time.ResultsThe multilevel analyses showed that employees procrastinated less on days following nights during which they slept better and that later chronotypes experienced more procrastination than earlier chronotypes. Our findings also supported the hypothesis that the relationship between sleep quality and procrastination is stronger for later chronotypes compared to earlier chronotypes on the Monday following the shift to daylight saving time. In other words, the lower the sleep quality of later chronotypes during the previous night, the more they procrastinated on the Monday following the shift to daylight saving time.DiscussionOur findings further corroborate the existing findings on the relevance of sleep and chronotype for well-being and performance at work.

A number of philosophical projects require a proper understanding of the modal aspects of agency, or of what I call ‘the agentive modalities.’ I propose a general account of the agentive modalities, one which takes as its primitive the decision-theoretic notion of an option. I relate this account to the standard semantics for ‘can’ and to the viability of some positions in the free will debates.

This paper aims to show that Frege’s and Hilbert’s mutual disagreement results from different notions of Anschauung and their relation to axioms. In the first section of the paper, evidence is provided to support that Frege and Hilbert were influenced by the same developments of 19th-century geometry, in particular the work of Gauss, Plücker, and von Staudt. The second section of the paper shows that Frege and Hilbert take different approaches to deal with the problems that the developments in 19th-century (...) geometry posed for the traditional Kantian philosophy of mathematics. Frege maintains that Anschauung is a source of knowledge by which we acknowledge geometrical axioms as true. For Hilbert, in contrast, axioms provide one of several correct “pictures” of reality. Hilbert’s position is thereby deeply influenced by epistemological ideas from Hertz and Helmholtz, and, in turn, influenced the neo-Kantian Cassirer. (shrink)

Frege ist bekannt für seinen Versuch, die Arithmetik aus der Logik herzuleiten. Doch welcher Begriff von Logik liegt diesem Projekt zugrunde? Wenn Logik die Grundlage der Arithmetik ist und die Arithmetik über Inhalte verfestigt, so muss die Logik selbst eine Wissenschaft mit eigenen Inhalten sein. Die Autorin zeigt, wie Frege logische Zeichen zu eigenständigen Begriffen aufwertet und dadurch eine inhaltliche Logikkonzeption überhaupt erst ermöglicht. In einem weiteren Schritt wird ein Kriterium vorgestellt, mit dessen Hilfe Frege logische Inhalte von den Inhalten (...) anderer Wissenschaften abgrenzt. Dabei wird jedoch deutlich, dass Frege bis in die 1890er Jahre braucht, um sich vollständig vom Kantischen Diktum zu lösen, die Logik sei nur ein negativer Probierstein der Wahrheit. Die Suche nach dem Grund, der Frege zu einer inhaltlichen Konzeption von Logik zwang, führt in die Geometriegeschichte des 19. Jahrhunderts. Vor ihrem Hintergrund werden schließlich die Anfangsparagraphen der Grundlagen der Arithmetik in einem neuen Licht interpretiert. (shrink)

This paper deals with the semantics of de dicto , de re and de se belief reports. First, I flesh out in some detail the established, classical theories that assume syntactic distinctions between all three types of reports. I then propose a new, unified analysis, based on two ideas discarded by the classical theory. These are: (i) modeling the de re/de dicto distinction as a difference in scope, and (ii) analyzing de se as merely a special case of relational de (...) re attitudes. The resurrection of these ideas takes place in a dynamic setting. My formalization of the first idea involves a modification of the presupposition-as-anaphora resolution algorithm for DRT. The second involves treating acquaintance relations as second-order presuppositions, to be bound in the context by means of higher-order unification, or accommodated if necessary. The resulting framework requires no syntactic distinctions between different modes of attitude, with the exception of a specific subclass of de se reports characterized by special ‘ de se pronouns’ (i.e. PRO and logophors). These special pronouns are handled in syntax; everything alse is passed on to the pragmatic resolution module as it appears on the surface. The more sophisticated contextual resolution process nonetheless ensures adequate output truth conditions for a variety of classical and novel puzzles. In particular, I compare the new pragmasemantic system to the classical, syntactic analysis with respect to iterated and quantified reports, and monstrously shifted indexicals. (shrink)

I argue that emojis are essentially little pictures, rather than words, gestures, expressives, or diagrams. ???? means that the world looks like that, from some viewpoint. I flesh out a pictorial semantics in terms of geometric projection with abstraction and stylization. Since such a semantics delivers only very minimal contents I add an account of pragmatic enrichment, driven by coherence and nonliteral interpretation. The apparent semantic distinction between emojis depicting entities (like ????) and those depicting facial expressions (like ????) I (...) analyze as a difference between truth-conditional and use-conditional pictorial content: ???? depicts what the world of evaluation looks like, while ???? depicts what the utterance context looks like.

From 1950 to 1952, statisticians W.G. Cochran, C.F. Mosteller, and J.W. Tukey reviewed A.C. Kinsey and colleagues’ methodology. Neither the history-and-philosophy of science literature nor contemporary theories of interdisciplinarity seem to offer a conceptual model that fits this forced interaction, which was characterized by significant power asymmetries and disagreements on multiple levels. The statisticians initially attempted to exclude all non-technical matters from their evaluation, but their political and personal investments interfered with this agenda. In the face of McCarthy’s witch hunts, (...) negotiations with Kinsey and his funding institutions became integral to the review group’s work. This paper analyzes the heavy burden of emotional and affective labor in this collaboration, the conflicts caused by competing visions of objectivity, and the uses of statistical knowledge to gain and sustain authority. Kinsey’s refusal to adopt the recommended probability sample damaged his already precarious position even further and marked him as a biased researcher who put his personal agenda above methodological rigor. Kinsey’s uncooperative demeanor can be explained by distrust resulting from numerous adverse reactions to his work and by fear of having his sexuality exposed. This case study illustrates that the very concept of valid numbers can become an arena for power struggles and that quantification alone does not guarantee productive exchanges across disciplines. It calls for a deeper conceptual analysis of the prerequisites for successful scientific collaborations. (shrink)

This article provides insight into the entwinement of the allegedly neutral category of handedness with questions of sex/gender, reproduction, dis/ability, and scientific authority. In the 1860s, Paul Broca suggested that the speech centre sat in the left brain hemisphere in most humans, and that right-handedness stemmed from this asymmetry. One century later, British psychologists Marian Annett and Chris McManus proposed biologically unconfirmed theories of how handedness and brain asymmetry were passed on in families. Their idea to integrate chance into genetic (...) models of handedness was novel, and so was their use of computerized statistics to parse out the incidence of handedness genotypes and phenotypes. Notwithstanding significant conceptual and methodological overlaps, McManus and Annett did not collaborate and proposed competing theories. I analyse the sexed/gendered dimensions of their controversy by drawing on published literature, unpublished documents, and oral history interviews. I first attend to the epistemological importance of sex/gender. Both psychologists published several iterations of their models, which increasingly relied on questions of sex/gender and reproduction. Annett additionally linked handedness with stereotypically gendered cognitive abilities. Second, I argue that using masculine-coded computer technologies contributed to Annett’s professional marginalization whereas similar methods endowed McManus with surplus authority. Finally, I show that Annett’s complicity in stabilizing sociocultural hierarchies within her theory mirrored her personal experience of marginalization based on sex/gender, age, education, and lack of institutional affiliation. This analysis exemplifies the entanglement of cognitive and social factors in scientific controversies and adds to the literature on 20th-century British women psychologists. (shrink)

Background Palliative care is an integral part of health care, which in term has become increasingly technologized in recent decades. Lately, innovative smart sensors combined with artificial intelligence promise better diagnosis and treatment. But to date, it is unclear: how are palliative care concepts and their underlying assumptions about humans challenged by smart sensor technologies (SST) and how can care benefit from SST? -/- Aims The paper aims to identify changes and challenges in palliative care due to the use of (...) SST. In addition, normative guiding criteria for the use of SST are developed. -/- Methods The principle of Total Care used by the European Association for Palliative Care (EAPC) forms the basis for the ethical analysis. Drawing on this, its underlying conceptions of the human and its socio-ethical aspects are examined with a phenomenological focus. In the second step, the advantages, limitations, and socio-ethical challenges of using SST with respect to the Total Care principle are explored. Finally, ethical-normative requirements for the application of SST are derived. -/- Results and Conclusion First, SST are limited in their measurement capabilities. Second, SST have an impact on human agency and autonomy. This concerns both the patient and the caregiver. Third, some aspects of the Total Care principle are likely to be marginalized due to the use of SST. The paper formulates normative requirements for using SST to serve human flourishing. It unfolds three criteria according to which SST must be aligned: (1) evidence and purposefulness, (2) autonomy, and (3) Total Care. (shrink)

English summary: The name Friedrich Nietzsche became important in the reception history of theology mainly due to his criticism of religion. In this study, Tabea Knura takes theological as well as pedagogical reception approaches and subsequently conceptualises impulses for an unprecedented debate with Nietzsche about religious education. She shows that the philosopher's critical analysis encourages looking critically at religious education, and that his reflections constantly initiate new construction processes, pointing to an affirmative and simultaneously epistemological attitude reflected in religious (...) education's mission. Questioning religious development processes therefore gives impetus to a cognitive-critical interpretation of reality that religious education must be based on. German description: Der Name Friedrich Nietzsche hat in der theologischen Rezeptionsgeschichte vor allem aufgrund seiner religionskritischen Ausserungen Bedeutung erlangt. Tabea Knura greift in dieser Studie theologische wie auch padagogische Rezeptionsansatze auf und konzipiert in der Folge Impulse fur eine bisher noch nicht erfolgte religionspadagogische Auseinandersetzung mit dem Philosophen. Sie zeigt, dass Nietzsches kritisches Denken dazu anregt, religiose Bildungsprozesse kritisch in den Blick zu nehmen. Seine religions- und bildungskritischen Uberlegungen initiieren immer neue Konstruktionsprozesse. Dies zeugt von einer affirmativen und zugleich erkenntniskritischen Haltung, die im religionspadagogischen Bildungsauftrag reflektiert wird. Religiose Entwicklungsprozesse zu hinterfragen wird so zum Impuls einer erkenntniskritischen Wirklichkeitsdeutung, die Fundament religioser Bildung sein muss. (shrink)

A fictional text is commonly viewed as constituting an invitation to play a certain game of make-believe, with the individual sentences written by the author providing the propositions we are to imagine and/or accept as true within the fiction. However, we can’t always take the text at face value. What narratologists call ‘unreliable narrators’ may present a confused or misleading picture of the fictional world. Meanwhile there has been a debate in philosophy about so-called ‘imaginative resistance’ in which we are (...) inclined to resist imagining (or even accepting as true in the fiction) what’s explicitly stated in the text. But if we can’t take the text’s word for it, how do we determine what’s true in a fiction? We propose an account of fiction interpretation in a dynamic setting (a version of DRT with a mechanism for opening, updating, and closing temporary ‘workspaces’) and combine this framework with belief revision logic. With these tools in hand we turn to modelling imaginative resistance and unreliable narrators. (shrink)

Novels like Fight Club or American Psycho are said to be instances of unreliable narration: the first person narrator presents an evidently distorted picture of the fictional world. The film adaptations of these novels are likewise said to involve unreliable narration. I resist this extension of the term ‘unreliable narration’ to film. My argument for this rests on the observation that unreliable narration requires a personal narrator while film typically involves an impersonal narrator. The kind of ambiguous story-telling that we (...) find in literary fiction with unreliable narrators, where for certain descriptions it is unclear whether what we’re told is an accurate account of what’s happening in the story world or not, can instead be achieved by conventionalized filmmaking techniques for reporting the contents of mental states, like the point of view shot, but especially the more ambiguous blended perspective shot.

In what follows, the difference between Frege’s and Schröder’s understanding of logical connectives will be investigated. It will be argued that Frege thought of logical connectives as concepts, whereas Schröder thought of them as operations. For Frege, logical connectives can themselves be connected. There is no substantial difference between the connectives and the concepts they connect. Frege’s distinction between concepts and objects is central to this conception, because it allows a method of concept formation which enables us to form concepts (...) from the logical connectives alone. Schröder in contrast unifies the distinction between concepts and objects, but keeps the distinction between logical connectives and what they connect. It will be argued that Frege’s particular way of perceiving logical connectives is crucial for his foundational project. (shrink)

Previous discussions of addiction have often focused on the question of whether addiction is a disease. This discussion distinguishes that question – the disease question – from the question of whether addiction is a disability. I argue that, however one answers the disease question, and indeed on almost any credible account of addiction, addiction is a disability. I then consider the implications of this view, or why it matters that addiction is a disability. The disease model of addiction has led (...) many to see addiction as primarily a medical problem, and to make medical treatment of the addicted person the first priority in addressing addiction. Once addiction is viewed as a disability, different concerns are foregrounded. The problem of addiction resides not only in the addicted person, but also in the social environment in which the addicted person finds herself. The fundamental ethical question about addiction is not how addicted persons can be treated or otherwise changed, but how a just society can make reasonable accommodations for addicted persons.

Semantics traditionally focuses on linguistic meaning. In recent years, the Super Linguistics movement has tried to broaden the scope of inquiry in various directions, including an extension of semantics to talk about the meaning of pictures. There are close similarities between the interpretation of language and of pictures. Most fundamentally, pictures, like utterances, can be either true or false of a given state of affairs, and hence both express propositions (Zimmermann, 2016; Greenberg, 2013; Abusch, 2015). Moreover, sequences of pictures, like (...) sequences of utterances, can be used to tell stories. Wordless picture books, comics, and film are cases in point. In this paper I pick up the project of providing a dynamic semantic account of pictorial story-telling, started by Abusch (2012) and continued by Abusch & Rooth (2017); Maier & Bimpikou (2019); Fernando (2020). More specifically, I propose here a semantics of speech and thought bubbles by adding event reference to PicDRT. To get there I first review the projection-based semantics for pictures (section 1), noting the fundamental distinction between symbolic and iconic meaning that makes speech bubbles especially interesting (section 2). I then review the dynamic PicDRT framework for pictorial narratives (section 3), add events (section 4), and propose an account of speech bubbles as quotational event modification (section 5). I end with a brief look at other conventional, symbolic enrichments in comics (section 6). (shrink)

Studies on temporality in Sidonius’ letters have so far been dominated by narratological approaches. This article proposes an additional perspective by focusing on social and ethical dimensions of time issues. Drawing from scholarship on both imperial epistolography and ancient timekeeping, I develop a framework for studying temporal-behavior patterns as negotiations of elite habitus. Many letters that provide insights in temporal habits (chronotypes) define also in- and out-groups based on temporal conventions (chronotopes). Time management displays a life order Sidonius can approve (...) or disapprove of. The motif of the clepsydra illustrates this connection between temporal habits and senatorial ethos most vividly.

This paper presents a social-theologically informed interpretation of the term integrity, as it occurs in fundamental law. It explores the manifestations of integrity violations and proceeds to draw an inference: an integrity violation can directly emanate from a misconception regarding integrity itself, as well as the implementation of protective measures that follow it. Integrity in its wholeness dimension is understood as open-endedness and non-seclusion rather than as a substantial, clearly definable characteristic of a person. This open-endedness and non-seclusion results from (...) the relational constitution of an individual. Consequently, it follows that a violation of integrity occurs when the open-endedness and non-seclusion of a person and their relational Becoming is hindered. The new definition of integrity is particularly important when it comes to the governance of new health technologies, especially Digital Twins that can become representatives of a person. Human integrity is non-violated only when it is understood as open to relational Becoming and this Becoming shows its expression in the mutual enabling and support of self-articulation. (shrink)

The use of Artificial Intelligence and Big Data in health care opens up new opportunities for the measurement of the human. Their application aims not only at gathering more and better data points but also at doing it less invasive. With this change in health care towards its extension to almost all areas of life and its increasing invisibility and opacity, new questions of transparency arise. While the complex human-machine interactions involved in deploying and using AI tend to become non-transparent, (...) the use of these technologies makes the patient seemingly transparent. Papers on the ethical implementation of AI plead for transparency but neglect the factor of the “transparent patient” as intertwined with AI. Transparency in this regard appears to be Janus-faced: The precondition for receiving help - e.g., treatment advice regarding the own health - is to become transparent for the digitized health care system. That is, for instance, to donate data and become visible to the AI and its operators. The paper reflects on this entanglement of transparent patients and (non-) transparent technology. It argues that transparency regarding both AI and humans is not an ethical principle per se but an infraethical concept. Further, it is no sufficient basis for avoiding harm and human dignity violations. Rather, transparency must be enriched by intelligibility following Judith Butler’s use of the term. Intelligibility is understood as an epistemological presupposition for recognition and the ensuing humane treatment. Finally, the paper highlights ways to testify intelligibility in dealing with AI in health care ex ante, ex post, and continuously. (shrink)

We propose an extension of Discourse Respresentation Theory (DRT) for analyzing pictorial narratives. We test drive our PicDRT framework by analyzing the way authors represent characters’ mental states and perception in comics. Our investigation goes beyond Abusch and Rooth (2017) in handling not just free perception sequences, but also a form of apparent perspective blending somewhat reminiscent of free indirect discourse.

Fictional names pose a difficult puzzle for semantics. We can truthfully maintain that Frodo is a hobbit, while at the same time admitting that Frodo does not exist. To reconcile this paradox I propose a way to formalize the interpretation of fiction as ‘prescriptions to imagine’ (Walton 1990) within an asymmetric semantic framework in the style of Kamp (1990). In my proposal, fictional statements are analyzed as dynamic updates on an imagination component of the interpreter’s mental state, while plain assertions (...) are updates on a belief component. Proper names – regular, empty, or fictional – are uniformly analyzed as presupposition triggers. The possibility of different attitude components referentially depending on each other is what ultimately allows us to account for the central paradox mentioned above. (shrink)

English direct discourse is easily recognized by e.g. the lack of a complementizer, the quotation marks (or the intonational contour they induce), and verbatim (`shifted') pronouns. Japanese employs the same complementizer for all reports, does not have a consistent intonational quotation marking, and tends to drop pronouns where possible. Some have argued that this just shows many Japanese reports are ambiguous: despite the lack of explicit marking, the underlying distinction is just as hard. On the basis of a number of (...) `mixed' examples, I claim that the line between direct and indirect em is blurred and I propose a unified analysis of speech reporting in which a general mechanism of mixed quotation replaces the classical two-fold distinction. (shrink)

I argue that free indirect discourse should be analyzed as a species of direct discourse rather than indirect discourse. More specifically, I argue against the emerging consensus among semanticists, who analyze it in terms of context shifting. Instead, I apply the semantic mechanisms of mixed quotation and unquotation to offer an alternative analysis where free indirect discourse is essentially a quotation of an utterance or thought, but with unquoted tenses and pronouns.

One of the still unsolved problems in liberal anarchism is a definition of social constituency in positive terms. Partially, this had been solved by the advancements of liberal discourse ethics. These approaches, built on praxeology as a universal framework for social formation, are detached from the need of any previous or external authority or rule for the discursive partners. However, the relationship between action, personal identity, and liberty within the process of a community becoming solely generated from the praxeological a (...) priori remains largely disputed. In order to develop a testable constitutional model, this study revises how the “ontological turn” was introduced into liberal theories and redefines the concept of liberty. Liberty is usually understood as a moral goal or measurement for just actions, as the generative principle of all social existence - individual and interpersonal. For this purpose, the function of performative contradiction within the mechanism of interpersonal “encounter”, as part of the co-generative process of the individual becoming and social formation was explored through the production of a game-based narrative historiography grounded on 19th century life writings. This narrative historiography was developed in the context of Swiss history, with a “design-based” research approach, and resulted in a prototype for networked storytelling through which the transformative learning process could be visible and the negotiation of competing individual visions of the future could be re-enacted.

Karttunen observes that a presupposition triggered inside an attitude ascription, can be filtered out by a seemingly inaccessible antecedent under the scope of a preceding belief ascription. This poses a major challenge for presupposition theory and the semantics of attitude ascriptions. I solve the problem by enriching the semantics of attitude ascriptions with some independently argued assumptions on the structure and interpretation of mental states. In particular, I propose a DRT-based representation of mental states with a global belief-layer and a (...) variety of labeled attitude compartments embedded within it. Hence, desires and other non-doxastic attitudes are asymmetrically dependent on beliefs. I integrate these mental state representations into a general semantic account of attitude ascriptions which relies on the parasitic nature of non-doxastic attitudes to solve Karttunen’s puzzle.

I propose a semantics for a class of English predicates characteristically associated with possibility. The central idea is that such predicates are typically associated with an ordering source, and that differences among them are due to differences in their ordering sources. The ‘dispositional predicates’ that have been central to philosophical discussions are shown to be derivable as a special case from this more general class.

The phenomenon of mixed quotation exhibits clear signs of both the apparent transparency of compositional language use and the opacity of pure quotation. I argue that the interpretation of a mixed quotation in- volves the resolution of a metalinguistic presupposition. The leading idea behind my proposal is that a mixed-quoted expression, say, “has an anomalous feature”, means what x referred to with the words ‘has an anomalous feature’. To understand how this solves the paradox, I set up a precise grammatical (...) framework, explicitly connecting various levels of linguistic analysis: phonological forms, categorial syntax, and a dynamic picture of the semantics–pragmatics interface. In this framework I formalize and evaluate a presuppositional account of mixed quotation. Finally, I address the phenomenon of unquotation and argue that it is an essential ingredient for empirically adequate analysis of mixed quotation in natural language. (shrink)

I present a concrete DRT-based syntax and semantics for the representation of mental states in the style of Kamp. This system is closely related to Recanati’s Mental Files framework, but adds a crucial distinction between anchors, the analogues of mental files, and attitudes like belief, desire and imagination. Attitudes are represented as separate compartments that can be referentially dependent on anchors. I show how the added distinctions help defend the useful notion of an acquaintance-based mental file against Ninan’s :368–377 2015) (...) recent challenge involving counterfactual de re attitudes.

The quotational theory of free indirect discourse postulates that pronouns and tenses are systematically unquoted. But where does this unquotation come from? Based on cases of apparent unquotation in direct discourse constructions (including data from Kwaza speakers, Catalan signers, and Dutch children), I suggest a general pragmatic answer: unquotation is essentially a way to resolve a conflict that arises between two opposing constraints. On the one hand, the reporter wants to use indexicals that refer directly to the most salient speech (...) act participants and their surroundings (Attraction). On the other hand, the semantics of direct discourse (formalized here in terms of event modification) entails the reproduction of referring expressions from the original utterance being reported (Verbatim). Unquotation (formalized here also in terms of event modification), allows the reporter to avoid potential conflicts between these constraints. Unquotation in free indirect discourse then comes out as a special case, where the salient source of attraction is the story protagonist and her actions, rather than the reporting narrator and his here and now.

A language is a system of signs used for communication, and linguists are tasked with, among other things, uncovering the syntax and semantics of such systems. In this paper I explore to what extent pictures fit this characterization of a language and hence would fall within the domain of linguistics. I conclude that at the very least there are well-defined systems of depiction for which we can give a precise semantics, in a familiar possible worlds framework, although pictorial propositions are (...) not derived via the linguistically familiar lexicon and recursive composition rules, but via geometric projection. I then show how sequences of pictures, like sequences of utterances, can be used to form coherent discourses. I explore in some detail extensions of the formal discourse semantics of Segmented Discourse Representation Theory to deal with comics, i.e. storytelling through picture sequences. I focus specifically on the representation of events in comics, and the integration of both symbolic and iconic elements. (shrink)

The Intergovernmental Platform on Biodiversity and Ecosystem Services have recently launched themselves as the UN-sanctioned instrument for conserving nature. They seek to establish themselves as the authority in this field alongside the well-known Intergovernmental Panel on Climate Change in climate science. Quickly following or even before recent publication of their conceptual framework in two biology journals, they were already underway building upon it. This headlong push, we believe, is ill advised. We show how the framework is unsound as a foundation (...) for further work—in a number of ways and perhaps even by its authors’ own lights. It is therefore urgent that the IPBES thoroughly and thoughtfully reconsider their framework before too much effort is wasted. (shrink)
