Alexander von Humboldt’s depictions of mountain vegetation are among the most iconic nineteenth century illustrations in the biological sciences. Here we analyse the contemporary context and empirical data for all these depictions, namely the _Tableau physique des Andes_ (1803, 1807), the _Geographiae plantarum lineamenta_ (1815), the _Tableau physique des Îles Canaries_ (1817), and the _Esquisse de la Géographie des plantes dans les Andes de Quito_ (1824/1825). We show that the Tableau physique des Andes does not reflect Humboldt and Bonpland’s field (...) data and presents a flawed depiction of plant occurrences and vertical succession of vegetation belts, arising from Humboldt’s misreading of La Condamine’s description (1751). Humboldt's 1815 depiction, by contrast, shows a distribution of high-vegetation belts that is consistent with La Condamine’s description, while the 1824 depiction drops innovations made in 1815 and returns to simply showing numerous species’ names, thus not applying Humboldt’s own earlier zonation framework. Our analysis of contemporary reactions to Humboldt’s TPA includes Francis Hall’s posthumously published 1834 illustration of Andean plant zonation near Quito and Humboldt’s reaction to Hall’s critique. Throughout his work on plant geography, Humboldt disregarded some of his own observations, or confused them. At stake was his reputation as an innovator in the field of plant geography and a discoverer of the sequence of high-elevation vegetation belts on the world’s mountains. (shrink)

The current German criticism of HUGO centers around the term ‘human dignity’; consenquentialist and autonomy-based arguments are used. The debate culminates in questioning the integrity of bioethics as a scholarly discipline and has created a heterogeneous coalition of disparate political and social groups that oppose any research that would facilitate genetic pre-selection of human characteristics.

This article proposes to reconceptualize the Hungarian photographer, artist and educator László Moholy-Nagy’s (1895–1946) inter-war call for a ‘new vision’ in order to grasp how artists presently experiment with photography and adjacent new technologies to explore the environmental, ecological and elemental dimension of media themselves. For Moholy-Nagy, photography represented a new way of seeing and experiencing the increasingly industrialized and automated world and a means of expanding our sensory perception. Drawing on recent scholarship of elemental media theory, I adapt Moholy-Nagy’s (...) interest in the materiality of photography and the atmospheric and medial dimensions of light itself to an environmentally attuned notion of ‘new visions’. Exemplified with discussion of recent works by Emilija Škarnulytė, Lesia Vasylchenko and Istvan Virag, I show how a number of contemporary artists likewise scrutinize photography’s (understood in an expanded way) material basis and atmospheric qualities to explore new forms of image-making, including CGI and synthetic aperture radar images, fitted to reflect the accelerated automation and ecological precarity that mark the early twenty-first century.

Nowadays, it is common that newly built hospitals are designed with single‐room accommodation, unlike in the past, where shared accommodation was the favoured standard. Despite this change in hospital design, very little is known about how single‐room accommodation affects nurses' work environment and nursing care. This study evaluates how the single‐room design affects nurses and nursing care in the single‐room hospital design. Nurses working in the single‐room design predominantly work alone with little opportunity for peer training, interaction and reflection. In (...) addition, the single‐room design affects the nurses' work environment due to changes in sensory stimulation and increased walking distances. Furthermore, a change in the discourse, namely, regarding the single room as the patient's home, makes the nurses react to queries, demands and tasks in a new way. Overall, the new hospital design forces the nurses into a more reactive role and affect their way of providing nursing care. Despite this, the nurses find single‐room accommodation beneficial for the patients and their nursing care. (shrink)

Cofactor squelching is the term used to describe competition between transcription factors (TFs) for a limited amount of cofactors in a cell with the functional consequence that TFs in a given cell interfere with the activity of each other. Since cofactor squelching was proposed based primarily on reporter assays some 30 years ago, it has remained controversial, and the idea that it could be a physiologically relevant mechanism for transcriptional repression has not received much support. However, recent genome‐wide studies have (...) demonstrated that signal‐dependent TFs are very often absent from the enhancers that are acutely repressed by those signals, which is consistent with an indirect mechanism of repression such as squelching. Here we review these recent studies in the light of the classical studies of cofactor squelching, and we discuss how TF cooperativity in so‐called hotspots and super‐enhancers may sensitize these to cofactor squelching.

Hobbes's political theory has traditionally been taken to be an endorsement of state power and a prescription for unconditional obedience to the sovereign's will. In this book, Susanne Sreedhar develops a novel interpretation of Hobbes's theory of political obligation and explores important cases where Hobbes claims that subjects have a right to disobey and resist state power, even when their lives are not directly threatened. Drawing attention to this broader set of rights, her comprehensive analysis of Hobbes's account of (...) political disobedience reveals a unified and coherent theory of resistance that has previously gone unnoticed and undefended. Her book will appeal to all who are interested in the nature and limits of political authority, the right of self-defense, the right of revolution, and the modern origins of these issues. (shrink)

This book investigates how collaborative scientific practice yields scientific knowledge. At a time when most of today’s scientific knowledge is created in research groups, the author reconsiders the social character of science to address the question of whether collaboratively created knowledge should be considered as collective achievement, and if so, in which sense. Combining philosophical analysis with qualitative empirical inquiry, this book provides a comparative case study of mono- and interdisciplinary research groups, offering insight into the day-to-day practice of scientists. (...) The book includes field observations and interviews with scientists to present an empirically-grounded perspective on much-debated questions concerning research groups’ division of labor, relations of epistemic dependence and trust.

In this article, we inquire into Maxine Sheets-Johnstone and Michele Merritt’s descriptions and use of dance improvisation as it relates to “thinking in movement.” We agree with them scholars that improvisational practices present interesting cases for investigating how movement, thinking, and agency intertwine. However, we also find that their descriptions of improvisation overemphasize the dimension of spontaneity as an intuitive “letting happen” of movements. To recalibrate their descriptions of improvisational practices, we couple Ezequiel Di Paolo, Thomas Buhrmann, and Xabier E. (...) Barandiaran’s enactive account of the constitution of agency with case studies of two expert performers of improvisation: a dancer and a musician. Our analyses hereof show that their improvisations unfold as a sophisticated oscillation of agency between specialized forms of mental and bodily control and, indeed, a more spontaneous “letting things happen.” In all, this article’s conclusions frame thinking in movement concerning improvisational practices as contextually embedded, purposively trained, and inherently relational.

Through advances in production and treatment technologies, transparent glass has become an increasingly versatile material and a global hallmark of modern architecture. In the shape of invisible barriers, it defines spaces while simultaneously shaping their lighting, noise, and climate conditions. Despite these unique architectural qualities, little is known regarding the human experience with glass barriers. Is a material that has been described as being simultaneously there and not there from an architectural perspective, actually there and/or not there from perceptual, behavioral, (...) and social points of view? In this article, we review systematic observations and experimental studies that explore the impact of transparent barriers on human cognition and action. In doing so, the importance of empirical and multidisciplinary approaches to inform the use of glass in contemporary architecture is highlighted and key questions for future inquiry are identified.

This article comprises a short case exemplifying ethical challenges arising for a participatory researcher working with Afghan women refugees during the Covid-19 pandemic in Germany. The researcher is an Iranian-German woman, qualified as a midwife, undertaking doctoral research on refugees’ access to reproductive health care. Disclosures about some women’s experience of domestic violence are made, which raise ethical issues for the researcher relating to personal-professional boundaries, roles and responsibilities. Two commentaries are given on this case from participatory researchers based in (...) Germany, UK and Austria. Both commentaries highlight the relevance of the ethics of care for participatory research and for this research in particular, which entails very close relationships between the doctoral researcher and the refugee women with whom she is researching. The first commentary analyses the research process in terms of Tronto’s five phases of care, while the second illustrates the importance of caring institutions in supporting researchers working on sensitive topics.

There is a trade-off between specificity and accuracy in existing models of belief. Descriptions of agents in the tripartite model, which recognizes only three doxastic attitudes—belief, disbelief, and suspension of judgment—are typically accurate, but not sufficiently specific. The orthodox Bayesian model, which requires real-valued credences, is perfectly specific, but often inaccurate: we often lack precise credences. I argue, first, that a popular attempt to fix the Bayesian model by using sets of functions is also inaccurate, since it requires us to (...) have interval-valued credences with perfectly precise endpoints. We can see this problem as analogous to the problem of higher order vagueness. Ultimately, I argue, the only way to avoid these problems is to endorse Insurmountable Unclassifiability. This principle has some surprising and radical consequences. For example, it entails that the trade-off between accuracy and specificity is in-principle unavoidable: sometimes it is simply impossible to characterize an agent’s doxastic state in a way that is both fully accurate and maximally specific. What we can do, however, is improve on both the tripartite and existing Bayesian models. I construct a new model of belief—the minimal model—that allows us to characterize agents with much greater specificity than the tripartite model, and yet which remains, unlike existing Bayesian models, perfectly accurate.

This article aims to explore the relation between body and space – specifically how the relation between the embodied awareness of movement and the sense of one’s body-space can be modified and changed deliberately in different kinds of dance practices. Using a multi-sited design, the ethnographical fieldwork, which formed the empirical ground for the study, was from the outset focused on acknowledging the diversity of the dancers’ practices. Each in their own way, the 13 professional dancers involved in the study (...) relate to and experience bodied potentialities, body-space and the spatiality of movement differently. Through their practice, they indicate that the body image is shaped through a multisensorial process of reification, and that seeing is to be related to a broader perceptual engagement. Furthermore, they exemplify how seeing can be deliberately used to expand the sense of their body-space and thereby to affect the spatiality of the fields of their embodied interaction. (shrink)

Imagine that, through no fault of your own, you nd yourself at the bottom of a deep well. Thugs have picked up an innocent person | call him Bob | and have thrown him down the well. Bob is now falling towards you. If you do nothing, your body will cushion Bob's otherwise lethal fall. This will guarantee his survival, but it will kill you. If you shoot your ray gun, you vaporize and kill Bob, thereby saving your life. Are (...) you morally permitted to shoot your ray gun?Most people believe that self-defence against an innocent threat such as Bob is permissible. Judith Thomson (1991) and Frances Kamm (1987) have tried to justify this widely held belief. Jeff McMahan (2002) and Michael Otsuka (1994) have argued against it. In this paper, I contend that arguments from both sides of the debate mistakenly take the existence of an important asymmetry between Bob and you for granted. That way, they miss how similar Bob and you are, in that both of you happen to nd yourselves, undeservingly and through no fault of your own, in a situation in which you can secure your own survival only if you kill an innocent person. In this paper, I argue that despite certain differences, we are justi ed in focusing on the simliarities between Bob and you, and that you should thus flip a coin to decide who should live (cf. Broome, 1991). By flipping a coin, you ensure that an indivisible good -- continuing one's life -- is distributed as fairly as is possible without wasting it. (shrink)

This volume brings together philosophical and interdisciplinary perspectives on improvisation. The contributions connect the theoretical dimensions of improvisation with different viewpoints on its practice in the arts and the classroom. The chapters address the phenomenon of improvisation in two related ways. On the one hand, they attend to the lived practices of improvisation both within and without the arts in order to explain the phenomenon. They also extend the scope of improvisational practices to include the role of improvisation in habit (...) and in planned action, at both individual and collective levels. Drawing on recent work done in the philosophy of mind, they also address questions such as whether improvisation is a single unified phenomenon, or whether it entails different senses that can be discerned theoretically and practically. Finally, they ask after the special kind of improvisational expertise which characterizes musicians, dancers, and other practitioners, an expertise marked by the artist's ability to participate competently in complex situations while deliberately relinquishing control. Philosophy of Improvisation will appeal to researchers working in philosophy, aesthetics, and pedagogy and the arts as well as practitioners involved in different kinds of music, dance, and theater performances.

I argue for the view that there are important similarities between knowledge and acting for a normative reason. I interpret acting for a normative reason in terms of Sosa’s notion of an apt performance. Actions that are done for a normative reason are normatively apt actions. They are in accordance with a normative reason because of a competence to act in accordance with normative reasons. I argue that, if Sosa’s account of knowledge as apt belief is correct, this means that (...) acting for a normative reason is in many respects similar to knowledge. In order to strengthen Sosa’s account of knowledge, I propose to supplement it with an appeal to sub-competences. This clarifies how this account can deal with certain Gettier cases, and it helps to understand how exactly acting for a normative reason is similar to apt belief. (shrink)

We frequently engage in activities that impose a risk of serious harm on innocent others in order to realise trivial benefits for ourselves or third parties. Many moral theories tie the evidence-relative permissibility of engaging in such activities to the size of the risk that an individual agent imposes. I argue that we should move away from such a reliance on quantified individual risks when conceptualising morally permissible risk imposition. Under most circumstances of interest, a conscientious reasoner will identify a (...) gap between the factors they deem potentially relevant to the riskiness of an agent’s behaviour, and the factors they are reasonably able to quantify. This then leads a conscientious reasoner to conclude that they cannot, in good faith, come up with a quantitative risk estimate that is genuinely tailored to the agent’s particular situation. Based on this, I argue that principles of morally permissible risk imposition fail to provide us with practical guidance if they ask us to take into account our agent-specific risks in a quantified manner. I also argue that principles of permissible risk imposition which appeal to quantified individual risks implausibly imply that it is frequently indeterminate whether engaging in some risky activity is morally permissible. For both of these reasons, I contend that principles of morally permissible risk imposition should make no reference to quantified individual risks. They should instead acknowledge that any quantitative estimates that an agent might usefully be able to consider will likely not be tailored to the agent’s idiosyncratic situation. (shrink)

In this extended essay, I argue that Frege plagiarized the Stoics --and I mean exactly that-- on a large scale in his work on the philosophy of logic and language as written mainly between 1890 and his death in 1925 (much of which published posthumously) and possibly earlier. I use ‘plagiarize' (or 'plagiarise’) merely as a descriptive term. The essay is not concerned with finger pointing or casting moral judgement. The point is rather to demonstrate carefully by means of detailed (...) evidence that there are numerous (over a hundred) and extensive parallels both in formulation and --more importantly-- in content between the Stoics and Frege, parallels so plentiful that one would be hard pressed to brush them off as coincidence. These parallels include several that appear to occur in no other modern works that were published before Frege’s own and were accessible to him. Additionally, a cluster of corroborating historical data is adduced to support the suggestion, showing how easy it would have to been for Frege to plagiarize the Stoics. This (first) part of the essay is easy to read and vaguely entertaining, or so I hope. -/- (Corrigendum: At school, Frege likely had seven, not ten, years of intensive Latin and four years of intensive ancient Greek courses.).

ArgumentSince the 1970s, Danish population registries were increasingly used for research purposes, in particular in the health sciences. Linked with a large number of disease registries, these data infrastructures became laboratories for the development of both information technology and epidemiological studies. Denmark's system of population registries had been centralized in 1924 and was further automated in the 1960s, with individual identification numbers (CPR-numbers) introduced in 1968. The ubiquitous presence of CPR-numbers in administrative routines and everyday lives created a continually growing (...) data archive of the entire population. The resulting national-level database made possible unprecedented record linkage, a feature epidemiologists and biomedical scientists used as a resource for population health research. The specific assemblages that emerged with their practices of data mining were constitutive of registry-based epidemiology as a style of thought and of a distinct relationship between science, citizens, and the state that emerged as “Scandinavian.”.

This paper examines whether an agent becomes liable to defensive harm by engaging in a morally permissible but foreseeably risk-imposing activity that subsequently threatens objectively unjustified harm. It first clarifies the notion of a foreseeably risk-imposing activity by proposing that an activity should count as foreseeably risk-imposing if an agent may morally permissibly perform it only if she abides by certain duties of care. Those who argue that engaging in such an activity can render an agent liable to defensive harm (...) ground this liability in the luck egalitarian thought that we may justly hold individuals responsible for the consequences of their voluntary choices. Against this, I argue that a luck egalitarian commitment to holding people responsible cannot, by itself, ground liability to defensive harm. It can help ground such liability only against the backdrop of a distributively just society, and only if further considerations speak morally in favour of attaching certain well-defined costs to individuals’ risk-imposing choices. I conclude by suggesting that if an account of liability applies robustly across distributively just and unjust contexts alike, then what grounds an agent’s liability is plausibly not her responsibility for threatening objectively unjustified harm, but her culpability for doing so.

In the face of increasing intervention in childbirth, ‘normal birth’ is currently being promoted by the World Health Organization, national governments, professional bodies and other organisations throughout the world. This paper takes a postmodernist stance and explores the idea of the ‘normal’ before going on to analyse normal childbirth, referring to concepts of the normal and the natural. It refers to historical developments in childbearing and lay organisations along with research relating to women’s views of childbirth, to question the appropriateness (...) of using ‘normal’ to describe the very individual experiences of childbirth. It laments the way in which women have been treated and arguably continue to be ‘cared for’ in maternity/obstetric services. It adds to the current discussion by recalling psychoanalytical theory and philosophical analysis to conclude with a call for future consideration of the ‘good‐enough’ birth instead of concentrating on promoting normal birth which is very difficult, if not impossible to define in retrospect, or to prospectively promote.

In this article, I show that Hegel’s philosophical articulation of the family is inextricably bound to his engagement with political economy by focusing on three central aspects of his theory of the family. Firstly, I analyze how Hegel construes the family as a historically distinct social dispositif and constitutive element of the modern order of property. I argue that Hegel’s construction of the family and its place in the modern order of property is not only gendered but also racialized. Secondly, (...) I focus on Hegel’s articulation of the nexus between the family and civil society and his critical diagnosis of the structural problems that result from it. Thirdly, I discuss Hegel’s concept of labor and the political-epistemic limitations of his problematization of civil society, which are bound to it. I draw attention to three aspects, namely the confinement of the concept of labor to civil society, Hegel’s rearticulation of the gendered matter/form distinction, and the relation between Hegel’s economic notion and speculative usage of “labor.” Finally, I consider briefly how a critical reading of Hegel’s articulation of the political economy of the family can provide productive insights for a multidimensional theory of the family today.

The purpose of this paper is to challenge some widespread assumptions about the role of the modal axiom 4 in a theory of vagueness. In the context of vagueness, axiom 4 usually appears as the principle ‘If it is clear (determinate, definite) that A, then it is clear (determinate, definite) that it is clear (determinate, definite) that A’, or, more formally, CA → CCA. We show how in the debate over axiom 4 two different notions of clarity are in play (...) (Williamson-style "luminosity" or self-revealing clarity and concealeable clarity) and what their respective functions are in accounts of higher-order vagueness. On this basis, we argue first that, contrary to common opinion, higher-order vagueness and S4 are perfectly compatible. This is in response to claims like that by Williamson that, if vagueness is defined with the help of a clarity operator that obeys axiom 4, higher-order vagueness disappears. Second, we argue that, contrary to common opinion, (i) bivalence-preservers (e.g. epistemicists) can without contradiction condone axiom 4 (by adopting what elsewhere we call columnar higher-order vagueness), and (ii) bivalence-discarders (e.g. open-texture theorists, supervaluationists) can without contradiction reject axiom 4. Third, we rebut a number of arguments that have been produced by opponents of axiom 4, in particular those by Williamson. (The paper is pitched towards graduate students with basic knowledge of modal logic.). (shrink)

This paper contends that Stoic logic (i.e. Stoic analysis) deserves more attention from contemporary logicians. It sets out how, compared with contemporary propositional calculi, Stoic analysis is closest to methods of backward proof search for Gentzen-inspired substructural sequent logics, as they have been developed in logic programming and structural proof theory, and produces its proof search calculus in tree form. It shows how multiple similarities to Gentzen sequent systems combine with intriguing dissimilarities that may enrich contemporary discussion. Much of Stoic (...) logic appears surprisingly modern: a recursively formulated syntax with some truth-functional propositional operators; analogues to cut rules, axiom schemata and Gentzen’s negation-introduction rules; an implicit variable-sharing principle and deliberate rejection of Thinning and avoidance of paradoxes of implication. These latter features mark the system out as a relevance logic, where the absence of duals for its left and right introduction rules puts it in the vicinity of McCall’s connexive logic. Methodologically, the choice of meticulously formulated meta-logical rules in lieu of axiom and inference schemata absorbs some structural rules and results in an economical, precise and elegant system that values decidability over completeness.

Increasing prevalence of depression poses a huge challenge to the healthcare systems, and the success rates of current standard therapies are limited. While 30% of treated patients do not experience a full remission after treatment, more than 75% of patients suffer from recurrent depressive episodes. Eye Movement Desensitization and Reprocessing therapy represents an emerging treatment option of depression, and preliminary studies show promising effects with a probably higher remission rate when compared to control-therapies such as cognitive behavioral therapy. In the (...) present study, 49 patients with severe depression were treated with an integrated systemic treatment approach including EMDR therapy that followed a specific protocol with a treatment algorithm for depression in a naturalistic hospital setting. Following their discharge from the hospital, the patients were followed up by a structured telephone interview after 3 and 12 months. 27 of the 49 patients fulfilled the Beck’s depression criteria of a full remission when they were discharged. At the follow-up interview, 12 months after discharge, 7 of the 27 patients reported a relapse, while the remaining 20 patients had stayed relapse-free. The findings of our observational study confirm reports of earlier studies in patients with depression, showing that EMDR therapy leads to a high rate of remission, and is associated with a decreased number of relapses. Patients with depression receiving EMDR treatment may be more resilient to stressors. (shrink)

ABSTRACT: Alexander of Aphrodisias’ commentaries on Aristotle’s Organon are valuable sources for both Stoic and early Peripatetic logic, and have often been used as such – in particular for early Peripatetic hypothetical syllogistic and Stoic propositional logic. By contrast, this paper explores the role Alexander himself played in the development and transmission of those theories. There are three areas in particular where he seems to have made a difference: First, he drew a connection between certain passages from Aristotle’s Topics and (...) Prior Analytics and the Stoic indemonstrable arguments, and, based on this connection, appropriated at least four kinds of Stoic indemonstrables as Aristotelian. Second, he developed and made use of a specifically Peripatetic terminology in which to describe and discuss those arguments – which facilitated the integration of the indemonstrables into Peripatetic logic. Third, he made some progress towards a solution to the problem of what place and interpretation the Stoic third indemonstrables should be given in a Peripatetic and Platonist setting. Overall, the picture emerges that Alexander persistently (if not always consistently) presented passages from Aristotle’s logical œuvre in a light that makes it appear as if Aristotle was in the possession of a Peripatetic correlate to the Stoic theory of indemonstrables.

Most descriptions of higher-order vagueness in terms of traditional modal logic generate so-called higher-order vagueness paradoxes. The one that doesn't is problematic otherwise. Consequently, the present trend is toward more complex, non-standard theories. However, there is no need for this.In this paper I introduce a theory of higher-order vagueness that is paradox-free and can be expressed in the first-order extension of a normal modal system that is complete with respect to single-domain Kripke-frame semantics. This is the system QS4M+BF+FIN. It corresponds (...) to the class of transitive, reflexive and final frames. With borderlineness defined logically as usual, it then follows that something is borderline precisely when it is higher-order borderline, and that a predicate is vague precisely when it is higher-order vague.Like Williamson's, the theory proposed here has no clear borderline cases in Sorites sequences. I argue that objections that there must be clear borderline cases ensue from the confusion of two notions of borderlineness—one associated with genuine higher-order vagueness, the other employed to sort objects into categories—and that the higher-order vagueness paradoxes result from superimposing the second notion onto the first. Lastly, I address some further potential objections. (shrink)

In his inaugural lecture at Cambridge as Regius Professor of Modern History in 1895, Lord Acton urged that the historian deliver moral judgments on the figures of his research. Acton declaimed: I exhort you never to debase the moral currency or to lower the standard of rectitude, but to try others by the final maxim that governs your own lives and to suffer no man and no cause to escape the undying penalty which history has the power to inflict on (...) wrong.1 In 1902, the year after Acton died, the president of the American Historical Association, Henry Lea, in dubious celebration of his British colleague, responded to the exordium with a contrary claim about the historian’s obligation, namely to render the facts of history objectively without subjective moralizing. Referring to Acton’s lecture, Lea declared: I must confess that to me all this seems to be based on false premises and to lead to unfortunate conclusions as to the objects and purposes of history, however much it may serve to give point and piquancy to a narrative, to stimulate the interests of the casual reader by heightening lights and deepening shadows, and to subserve the purpose of propagating the opinions of the writer.2 As our colleague Peter Novick has detailed in his great account of the American historical profession, by the turn of the century historians in the United States had begun their quest for scientific status, which for most seemed to preclude the leakage of moral opinion into the objective recovery of the past—at least in an overt way. Peter also catalogues the stumbling failures of this noble dream, when political partisanship and rampant nationalism sullied the ideal.3 Historians in our own time continue to be wary of rendering explicit moral pronouncements, thinking it a derogation of their obligations. On occasion, some historians have been moved to embrace the opposite attitude, especially when considering the horrendous events of the twentieth century—the Holocaust, for instance.. (shrink)

Intuitionistic logic provides an elegant solution to the Sorites Paradox. Its acceptance has been hampered by two factors. First, the lack of an accepted semantics for languages containing vague terms has led even philosophers sympathetic to intuitionism to complain that no explanation has been given of why intuitionistic logic is the correct logic for such languages. Second, switching from classical to intuitionistic logic, while it may help with the Sorites, does not appear to offer any advantages when dealing with the (...) so-called paradoxes of higher-order vagueness. We offer a proposal that makes strides on both issues. We argue that the intuitionist’s characteristic rejection of any third alethic value alongside true and false is best elaborated by taking the normal modal system S4M to be the sentential logic of the operator ‘it is clearly the case that’. S4M opens the way to an account of higher-order vagueness which avoids the paradoxes that have been thought to infect the notion. S4M is one of the modal counterparts of the intuitionistic sentential calculus and we use this fact to explain why IPC is the correct sentential logic to use when reasoning with vague statements. We also show that our key results go through in an intuitionistic version of S4M. Finally, we deploy our analysis to reply to Timothy Williamson’s objections to intuitionistic treatments of vagueness. (shrink)

ABSTRACT: This is a short companion piece to my ‘Found in Translation – Aristotle’s Nicomachean Ethics III.5 1113b7-8 and its Reception’ in which I examine in close textual analysis the philosophical question whether these two lines from the Nicomachean Ethics provide any evidence that Aristotle discussed free choice – as is not infrequently assumed. The result is that they do not, and that the claim that they do tends to be based on a mistranslation of the Greek. (There is some (...) inevitable overlap with Part 1 of the 'Found in Translation' paper.). (shrink)

We argue that the extant evidence for Stoic logic provides all the elements required for a variable-free theory of multiple generality, including a number of remarkably modern features that straddle logic and semantics, such as the understanding of one- and two-place predicates as functions, the canonical formulation of universals as quantified conditionals, a straightforward relation between elements of propositional and first-order logic, and the roles of anaphora and rigid order in the regimented sentences that express multiply general propositions. We consider (...) and reinterpret some ancient texts that have been neglected in the context of Stoic universal and existential propositions and offer new explanations of some puzzling features in Stoic logic. Our results confirm that Stoic logic surpasses Aristotle’s with regard to multiple generality, and are a reminder that focusing on multiple generality through the lens of Frege-inspired variable-binding quantifier theory may hamper our understanding and appreciation of pre-Fregean theories of multiple generality.

ABSTRACT: In this paper I argue that the ‘discovery’ of the problem of causal determinism and freedom of decision in Greek philosophy is the result of a combination and mix-up of Aristotelian and Stoic thought in later antiquity; more precisely, a (mis-)interpretation of Aristotle’s philosophy of deliberate choice and action in the light of Stoic theory of determinism and moral responsibility. The (con-)fusion originates with the beginnings of Aristotle scholarship, at the latest in the early 2nd century AD. It undergoes (...) several developments, absorbing Epictetan, Middle-Platonist, and Peripatetic ideas; and it leads eventually to a concept of freedom of decision and an exposition of the ‘free-will problem’ in Alexander of Aphrodisias’ On Fate and in the Mantissa ascribed to him.

In this article, I defend the inviolability approach to solving the paradox of deontology against a criticism raised by Michael Otsuka. The paradox of deontology revolves around the question whether it should always be permissible to infringe someone's right to non-interference when this would serve to minimize the overall number of comparable rights infringements that occur. According to the inviolability approach, rights to non-interference protect and give expression to our personal sovereignty, which is not advanced through the minimization of rights (...) infringements. This seems to dissolve the paradox. Otsuka, however, contends that the proposed solution relies on too narrow an understanding of personal sovereignty. He argues that there is an enforceability dimension to personal sovereignty that would seem to undermine the inviolability approach. While I agree with Otsuka that enforceability is an important aspect of personal sovereignty, I argue that properly construed, the enforceability dimension of personal sovereignty does not undermine the inviolability approach.

This paper shows that, for the Hertz–Gentzen Systems of 1933, extended by a classical rule T1 and using certain axioms, all derivations are analytic: every cut formula occurs as a subformula in the cut’s conclusion. Since the Stoic cut rules are instances of Gentzen’s Cut rule of 1933, from this we infer the decidability of the propositional logic of the Stoics. We infer the correctness for this logic of a “relevance criterion” and of two “balance criteria”, and hence that a (...) particular derivable sequent has no derivation that is “normal” in the sense that the first premiss of each cut is cut-free. We also infer that Cut is not admissible in the Stoic system, based on the standard Stoic axioms, the T1 rule and the instances of Cut with just two antecedent formulae in the first premiss.

ABSTRACT: This paper traces the earliest development of the most basic principle of deduction, i.e. modus ponens (or Law of Detachment). ‘Aristotelian logic’, as it was taught from late antiquity until the 20th century, commonly included a short presentation of the argument forms modus (ponendo) ponens, modus (tollendo) tollens, modus ponendo tollens, and modus tollendo ponens. In late antiquity, arguments of these forms were generally classified as ‘hypothetical syllogisms’. However, Aristotle did not discuss such arguments, nor did he call any (...) arguments ‘hypothetical syllogisms’. The Stoic indemonstrables resemble the modus ponens/tollens arguments. But the Stoics never called them ‘hypothetical syllogisms’; nor did they describe them as ponendo ponens, etc. The tradition of the four argument forms and the classification of the arguments as hypothetical syllogisms hence need some explaining. In this paper, I offer some explanations by tracing the development of certain elements of Aristotle’s logic via the early Peripatetics to the logic of later antiquity. I consider the questions: How did the four argument forms arise? Why were there four of them? Why were arguments of these forms called ‘hypothetical syllogisms’? On what grounds were they considered valid? I argue that such arguments were neither part of Aristotle’s dialectic, nor simply the result of an adoption of elements of Stoic logic, but the outcome of a long, gradual development that begins with Aristotle’s logic as preserved in his Topics and Prior Analytics; and that, as a result, we have a Peripatetic logic of hypothetical inferences which is a far cry both from Stoic logic and from classical propositional logic, but which sports a number of interesting characteristics, some of which bear a cunning resemblance to some 20th century theories.
