This concise book introduces nonphysicists to the core philosophical issues surrounding the nature and structure of space and time, and is also an ideal resource for physicists interested in the conceptual foundations of space-time theory. Tim Maudlin's broad historical overview examines Aristotelian and Newtonian accounts of space and time, and traces how Galileo's conceptions of relativity and space-time led to Einstein's special and general theories of relativity. Maudlin explains special relativity using a geometrical approach, emphasizing intrinsic space-time structure rather than (...) coordinate systems or reference frames. He gives readers enough detail about special relativity to solve concrete physical problems while presenting general relativity in a more qualitative way, with an informative discussion of the geometrization of gravity, the bending of light, and black holes. Additional topics include the Twins Paradox, the physical aspects of the Lorentz-FitzGerald contraction, the constancy of the speed of light, time travel, the direction of time, and more.Introduces nonphysicists to the philosophical foundations of space-time theory Provides a broad historical overview, from Aristotle to Einstein Explains special relativity geometrically, emphasizing the intrinsic structure of space-time Covers the Twins Paradox, Galilean relativity, time travel, and more Requires only basic algebra and no formal knowledge of physics.

SummaryOverweight and obesity constitute a major and increasing health and welfare problem throughout the world. Assessing the multifaceted mechanisms – biological, environmental and behavioural – behind this development is a crucial task in medical, social and economic sciences. We are, therefore, grateful to have been given the opportunity to, once again, discuss whether the risk of divorce may be one of the factors influencing the incentives of becoming overweight or obese and, hence, ultimately the physical appearance among the married. In (...) this Debate, colleagues Schneider and Grimps present the results of a multilevel analysis, in which they could not identify any statistically significant association between body mass index and divorce risk among married people. Thus, they question the findings, previously published in this Journal. The Schneider and Grimps arguments are not convincing, however. So, we still claim that the statistical material at hand does, indeed, imply that divorce risk at the national level may well influence the weight of the married. (shrink)

Aspects of Psychologism is a penetrating look into fundamental philosophical questions of consciousness, perception, and the experience we have of our mental lives. Psychologism, in Tim Crane’s formulation, presents the mind as a single subject-matter to be investigated not only empirically and conceptually but also phenomenologically: through the systematic examination of consciousness and thought from the subject’s point of view.

Two familiar worldviews dominate Western philosophy: materialist atheism and the benevolent God of the Abrahamic faiths. Tim Mulgan explores a third way. Ananthropocentric Purposivism claims that there is a cosmic purpose, but human beings are irrelevant to it. Purpose in the Universe develops a philosophical case for Ananthropocentric Purposivism that it is at least as strong as the case for either theism or atheism. He draws on a range of secular and religious ethical traditions to conclude that a non-human-centred cosmic (...) purpose can ground a distinctive human morality. Our moral practices, our view of the moral universe, and our moral theory are all transformed if we shift from the familiar choice between a universe without meaning and a universe where humans matter to the less self-aggrandising thought that, while it is about something, the universe is not about us.

Safe Safety arguments are key components in a safety case. Too often, safety arguments are constructed without proper reasoning. To address this, we argue that informal logic argument schemes have important roles to play in safety argument construction and reviewing process. Ten commonly used reasoning schemes in computer system safety domain are proposed. The role of informal logic dialogue games in computer system safety arguments reviewing is also discussed and the intended work in this area is proposed. It is anticipated (...) that this work will contribute toward the development of computer system safety arguments, and help to move forward the interplay between research in informal logic and research in computer system safety engineering.

What does it mean to be a citizen in a multicultural society? And what role must patriotism play in defining our relationship with our country and fellow citizens? In The Virtuous Citizen Tim Soutphommasane answers these questions with a critical defence of liberal nationalism. Considering a range of contemporary political debates from Europe, North America and Australia, over issues including multiculturalism, national history, civic education and immigration, Soutphommasane argues that a love of country should be valued alongside tolerance, mutual respect (...) and public reasonableness as a civic virtue. A liberal form of patriotism, grounded in national identity, is, if anything, essential for political stability in a diverse society. This book is required reading not only for political theorists and philosophers but also for researchers and professionals in political science, sociology, history and public policy. (shrink)

Jakob von Uexküll’s (1864-1944) account of Umwelt has been proposed as a mediating concept to bridge the gap between ecological psychology’s realism about environmental information and enactivism’s emphasis on the organism’s active role in constructing the meaningful world it inhabits. If successful, this move would constitute a significant step towards establishing a single ecological-enactive framework for cognitive science. However, Uexküll’s thought itself contains different perspectives that are in tension with each other, and the concept of Umwelt is developed in representationalist (...) terms that conflict with the commitments of both enactivism and ecological psychology. One central issue shared by all these approaches is the problem of how a living being experiences its environment. In this paper, we will look at Uexküll’s reception in French philosophy and highlight the different ways in which the concept of Umwelt functions in the work of Georges Canguilhem, Maurice Merleau-Ponty, and Gilles Deleuze. This analysis helps clarify different aspects of Uexküll’s thought and the deeper philosophical implications of importing his concepts into embodied cognitive science. This paper is part of a recent trend in which enactivism engages with continental philosophy in a way that both deepens and transcends the traditional links to phenomenology, including most recently the thought of Georg W. F. Hegel and Gilbert Simondon. However, no more than a brief outline and introduction to the potentials and challenges of this complex conceptual intersection can be given here. Our hope is that it serves to make more explicit the philosophical issues that are at stake for cognitive science in the question of experienced environments, while charting a useful course for future research.

Excellence and frontier research have made inroads into European research policymaking and structure political agendas, funding programs and evaluation practices. The two concepts travelled a long way from the United States and have derived from contexts outside of science. Following their conceptual journey, we ask how excellence and frontier research have percolated into European science and higher education policies and how they have turned into lubricants of competition that buttress an ongoing reform process in Europe.

Dynamic and proof-conditional approaches to discourse (exemplified by Discourse Representation Theory and Type-Theoretical Grammar, respectively) are related through translations and transitions labeled by first-order formulas with anaphoric twists. Type-theoretic contexts are defined relative to a signature and instantiated modeltheoretically, subject to change.

Events and situations are represented by strings of temporally ordered observations, on the basis of which the events and situations are recognized. Allen’s basic interval relations are derived from superposing strings that mark interval boundaries, and Kamp’s event structures are constructed as projective limits of strings. Observations are generalized to temporal propositions, leading to event-types that classify event-instances. Working with sets of strings built from temporal propositions, we obtain natural notions of bounded entailment from set inclusions. These inclusions are decidable (...) if the sets are accepted by finite automata. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 10.2 (2005) 175-194 [Access article in PDF] Measure for Measure The Reliance of Human Knowledge on the Things of the World Tim Adamson When all things were in disorder, God created in each thing in relation to itself, and in all things in relation to each other, all the measures and harmonies which they could possibly receive. —Plato, Timaeus (69b) Is my body a thing, (...) is it an idea? It is neither, being the measurant of the things. We will therefore have to recognize an ideality that is not alien to the flesh, that gives it its axes, its depth, its dimensions. —Maurice Merleau-Ponty (1968, 152) The search for truths differs from the search for truth criteria in more ways than those that are immediately obvious. —M. C. Dillon (1997, 9) The notion that all knowledge is a form of measurement can be traced back to the Socratic insight that knowledge requires the presence of some standard against which things are measured. We cannot account for our knowledge of things, Socrates argued, without appealing to some prior capacity we have for recognizing, comparing, or measuring things in terms of something else, for example, a concept or definition. In the modern era, Kant extended this insight to include perception as such, [End Page 175] arguing that even though our perceptual experience seems to be direct and immediate, upon reflection we know that some process of mediation must be at work which enables us to have a stable experience of objects. Faced with such insights, we are compelled to ask how such measuring is possible. If experience and knowledge rely on some capacity for measurement, what is measurement and what does it entail?The most common contemporary answer to this question can be found in notion that our experience and knowledge are "constructed" by distinctly human, that is, cultural factors. Having abandoned Kant's notion of a priori knowledge and its various Idealist offshoots, contemporary constructivism nonetheless maintains that cultural structures (although not fixed or permanent ones) serve as the basic principles upon which experience and knowledge are built. Such a view has some merit, insofar as it enables us to acknowledge the mediated character of our experience, while also avoiding the problematic claims of traditional idealism. But as appealing as this view is, it raises the question of the place and role of nature in our experience. From a constructivist point of view, although we may acknowledge that our experience and knowledge depend in crucial ways upon natural elements and events, it can often seem naive to discuss the role of such natural factors within experience—except, that is, as we admit that nature itself is "constructed" by culture, for example, language, conceptual systems, theoretical constructs, ideology, political power, institutional practices, and so forth. That is, although we no longer accord cultural factors an a priori or absolute status, we remain convinced that in fact cultural norms play the final, determining role in shaping our experience. In the end, we have come to believe, it is culture that measures and defines nature, not vice versa.My aim in this essay is to articulate an alternative view of the measurement involved in human experience and knowledge, one which helps us to overcome the privileging of culture over nature that still plagues contemporary thought. My account is inspired by Merleau-Ponty's philosophy of the body, particularly his notion that the human body serves as a "measurant of things." There are two key components of this claim. First, it describes the body's general capacity for measurement, and does not appeal to any specific measure or standard of measurement. As a measurant, the body is not any particular measure; rather, it is a thing that measures, an element of the natural world that brings measurement to the [End Page 176] things it encounters, thus bringing meaning into our experience. Second, the body's capacity to measure shows how our natural being as bodies is inherently meaningful, because measurement is, as we shall see... (shrink)

Numerical probabilities are eliminated in favor of qualitative notions, with an eye to isolating what it is about probabilities that is essential to judgements of acceptability. A basic choice point is whether the conjunction of two propositions, each acceptable, must be deemed acceptable. Concepts of acceptability closed under conjunction are analyzed within Keisler's weak logic for generalized quantifiers — or more specifically, filter quantifiers. In a different direction, the notion of a filter is generalized so as to allow sets with (...) probability non-infinitesimally below 1 to be acceptable. (shrink)

The idea that temporal propositions are vague predicates is examined with attention to the nature of the objects over which the predicates range. These objects should not, it is argued, be identified once and for all with points or intervals in the real line (or any fixed linear order). Context has an important role to play not only in sidestepping the Sorites paradox (Gaifman 2002) but also in shaping temporal moments/extent (Landman 1991). The Russell-Wiener construction of time from events (Kamp (...) 1979) is related to a notion of context given by a string of observations, the vagueness in which is brought out by grounding the observations in the real line. With this notion of context, the context dependency functions in Gaifman 2002 are adapted to interpret temporal propositions. (shrink)

A distinction is drawn between situations as indices required for semantically evaluating sentences and situations as denotations resulting from such evaluation. For atomic sentences, possible worlds may serve as indices, and events as denotations. The distinction is extended beyond atomic sentences according to formulae-as-types and applied to implicit quantifier domain restrictions, intensionality and conditionals.

Reichenbach's event, reference and speech times are interpreted semantically by stringing and superposing sets of temporal formulae, structured within regular languages. Notions of continuation branches and of inertia, bound (in a precise sense) by reference time, are developed and applied to the progressive and the perfect.

Taking its title from the discussion of a ‘new Meno’ to be found in Difference and Repetition, through an examination of the link between learning and thinking set out across Deleuze's work this paper charts the important sense in which philosophical thought is characterised by an apprenticeship. The claim is that just as certain aesthetic and biological processes involve inscrutable and non-resembling elements that cannot be known in advance, the experience of learning is one oriented by unforseen encounters. With a (...) view to a peculiarly heuristic use of dictionaries in the case of language learning, the paper shows how the logic of this experience is one whereby the putative meaning of things does not enjoy a priority over the immanence of their expression.

Open peer commentary on the article “Beyond Individual-Centred 4E Cognition: Systems Biology and Sympoiesis” by Mads Julian Dengsø & Michael David Kirchhoff. Abstract: Dengsø and Kirchhoff’s inspiring proposal to drop the individual-centeredness of autopoiesis in favor of a view based on sympoiesis and developmental systems theory (DST) has two problems: (a) It is not clear that the points they raise as arguments against individual-centered 4E cognition are incompatible with those views and many of them are already included in Ezequiel Di (...) Paolo’s account of enaction. (b) They give no clear account of how 4E cognition will account for agency as purposive behavior once it discards its current, individual-centered, accounts of it.

The cultural red king effect occurs when discriminatory bargaining practices emerge because of a disparity in learning speed between members of a minority and a majority. This effect has been shown to occur in some Nash Demand Game models and has been proposed as a tool for shedding light on the origins of sexist and racist discrimination in academic collaborations. This paper argues that none of the three main strategies used in the literature to support the epistemic value of these (...) models—structural similarity, empirical confirmation, and how-possibly explanations—provides strong support for this modeling practice in its present form.

Taken at face value the introduction in 2021 of Australia’s News Media and Digital Platforms Mandatory Bargaining Code (“the Code”) may appear “world leading,” innovative, and, in general, a productive and strategic intervention to reverse the decline of public interest journalism. It is claimed that in the Australian news industry context, an annual transfer of around $200 million between two platform companies – Google and Meta – and news businesses has now been put in place (Sims, 2022). All major news (...) media companies in Australia, if not smaller more independent ones, have greatly benefitted from the new Code, and anecdotally it appears that the funding has resulted in the creation of significant numbers of new journalists being hired. Yet the exact investment destination and ultimate beneficiaries of the funding are not known beyond the corporate walls of the recipients. The article points to the transparency and sustainability problems inherent to the new Code, arguing that an alternative approach to funding public interest journalism might be a levy funded by the platforms.

This course aims to assess the principle of compositionality (CP) and how it fits with recent developments in natural language interpretation, especially those that stress the role of context. We first try to lay down a suitable formal framework for CP, reviewing proposals by Montague, Janssen, Hendriks, Kracht and Hodges. Versions of CP of varying strength are formulated, and some recent results on the existence of compositional semantics and the (much debated) issue of the empirical import of CP discussed. Complementing (...) CP is the notion of context which, under modern (e.g. "dynamic") conceptions, not only conditions interpretation but also is transformed during interpretation. The tension between CP and context is examined relative to problems of anaphora, presupposition, idioms and ambiguity. A somewhat un-orthodox computational application of CP is suggested, emphasizing co-inductive aspects of interpretation that cut across the divide between model-theoretic and proof-theoretic approaches, and between procedural and declarative styles.

The principle of compositionality states that the meaning of a complex expression e is determined by the meaning of its parts and how those parts are put together to form e. The Context Principle states that the meaning of a word w can only be given in the context of a sentence in which w appears. X can roughly be related to PC if one takes a complex expression to be a sentence, and its parts to be the words in (...) it. Compositionality is a constraint on transformations of the structures that yield what can be called meanings. There is a tradition in formal semantics of basing compositionally derived meanings on a “reality” external to the language users, employing model-assignment pairs for this purpose. (shrink)

The Yale Shooting Problem introduced by Steve Hanks & Drew McDermott (1987) is a well-known test case of non-monotonic temporal reasoning. There is a sequence of situations. In the initial situation a gun is not loaded and the target is alive. In the next situation the gun is loaded. Eventually, a shot is fired, perhaps with fatal consequences. In this scenario there are two "fluents", alive and loaded, and two actions, load and shoot. Being loaded and being alive are inert (...) propositions in the sense that if they are true at a given moment, they will be true at the next moment unless some action such as.. (shrink)

This paper is a response to Ted Toadvine’s article “Gestalts and Refrains: On the Musical Structure of Nature,” in Environmental Philosophy 2.2 (2005). We propose a more generous interpretation of Naess’s gestalt ontology, one that we believe mitigates Toadvine’s criticisms. Gestalt ontology and refrain ontology offer two different yet compatible ontologies for environmental philosophers searching for viable alternatives to scientific reductionism. Encouraging many ontologies also encourages a rich philosophical pluralism.

Unter dem Titel Hans Blumenberg: Pädagogische Lektüren erkunden die Autorinnen und Autoren Hans Blumenbergs Werk nach bildungsphilosophischen und erziehungswissenschaftlichen Problem- und Fragestellungen. Das Werk des Münsteraner Philosophen erscheint der Erziehungswissenschaft bisher nicht nur deshalb als terra incognita, weil er sich zu pädagogischen Themen kaum geäußert hat, sondern auch, weil sein Werk bereits zu Lebzeiten einen beachtlichen Umfang aufwies und durch zahlreiche Veröffentlichungen aus dem Nachlass nochmals bedeutend erweitert wurde. Nur vereinzelt und verstreut liegen bisher disziplinbezogene Anschlussversuche vor. Mit diesem Band (...) wird deshalb der erste Sammelband zur erziehungswissenschaftlichen Blumenberg-Rezeption vorgelegt, der Beiträge zu Blumenbergs Metaphorologie, Anthropologie und seiner kritischen Auseinandersetzung mit Platons Höhlenmythos zusammenträgt.

Humans discount rewards as a function of the delay to their receipt. This tendency is referred to as delay discounting and has been extensively researched in the last decades. The magnitude effect and the trait effect are two phenomena which have been consistently observed for a variety of reward types. Here, we wanted to investigate if these effects also occur in the context of the novel but widespread reward types of Instagram followers and likes and if delay discounting of these (...) outcomes is related to self-control and Instagram screen time. In a within-subject online experiment, 214 Instagram users chose between smaller, immediate and larger, delayed amounts of hypothetical money, Instagram followers and likes. First, we found that the magnitude effect also applies to Instagram followers and likes. Second, delay discounting of all three reward types was correlated, providing further evidence for a trait influence of delay discounting. Third, no relationships were found between delay discounting and self-control as well as Instagram screen time, respectively. However, a user’s average like count was related to delay discounting of Instagram likes. (shrink)

Following the work of Barbara Cassin, this paper proposes to examine certain ways of speaking that Aristotle described as not so much human as plant-like [homoioi phutôi] and to consider whether these non-human ways of speaking might yet adduce forms of discourse that serve to model how central principles of justice can be thought. The paper does this by drawing upon Cassin’s extensive engagement with Sophistry in the classical world together with her concerted interest in the activities of the Truth (...) and Reconciliation Commission in post-apartheid South Africa. When Aristotle, in book Gamma of the Metaphysics, dismissed the speech of those spoke “otherwise” (for example, those who failed to obey the law of non-contradiction) he formalised a chauvinism that philosophy had, at least since Plato, derided as sophistry. For Cassin, however, this presumed superiority of one way of speaking over another is something that holds true only when the grounds and elemental terms of a discourse have been and remain uncontested. In this way, language in Aristotle is regulated in advance, and determines what is admissible in the court of discourse according to prescribed and recognisable forms. Accordingly, illuminated by Heidegger and yet (like Arendt) departing from his conclusions, Cassin explores the sense in which language is something ontologically constitutive but in a manner that contests rather than secures its speakers’ relations to one another. In place of a metaphysics and ethics of belonging and authenticity, Cassin’s work is oriented by figures of precarity and exile such that truth is not so much something to be discovered, once and for all, but to be contested, negotiated, and re-worked each and every time. Key to this form of discourse, the paper will claim, is the uniquely non-juridical approach to justice undertaken by the Truth and Reconciliation Commission. Here, as Cassin explains, rather than a logic of individual rights and wrongs, there is a performative role for those involved. This “politics via discourse” dislocates the identity of received (rational) subjects and allows for narrative testimony itself not only to bear witness to a past but to signal a future – one based not on the apportionment or allocation of justice but on its ongoing struggle (an eristics or agonistics) for a humanity to come.

The spiritual torsion and material complexity so characteristic of Baroque aesthetics is something that extends to (or perhaps, better, issues from) the intension of the term itself. This much is evident in the sense that, since the twentieth century, various projects have proposed such notions as a medical-baroque, a postcolonial-baroque, and a digital-baroque. Beyond any given object of analysis, then, in this way the Baroque adduces the concepts by which any inquiry into objects might take place. As such, the Baroque (...) can be said to be that which signals the ongoing relation of thought to the world, of ‘the inside’ to ‘the outside’ (while at the same time problematising the priority of either side over the other). Indeed, following certain post-Kantian readings of Leibnizian philosophy, the Baroque is to be regarded not so much as something to be understood but rather as a frenzied development of the understanding itself.

Although Thomas More is an exemplary figure of both personal and moral integrity, his Utopia is not straightforwardly ‘integer’ in another meaning of the term, i.e., it does not unequivocally describe a ‘whole, intact or pure’ conception of the ideal society. Rather, Utopia is patently ambiguous and challenges the reader to disambiguate the narrative and to make up his own mind on how to construct the ideal society. In this paper, I analyze utopias and dystopias in general as evaluative thought (...) experiments that appeal to our imagination and deploy possible worlds. Subsequently, I argue that More’s Utopia is a successful evaluative thought experiment that actually underscores More’s integrity, because by means of its exacerbated ambiguity, it both triggers and properly respects the deliberation and evaluation of the reader in his capacity as thought experimenter.

We provide complete classifications of algebras of partial maps for a significant swathe of combinations of operations not previously classified. Our focus is the many subsidiary operations that arise in recent considerations of the ‘override’ and ‘update’ operations arising in specification languages. These other operations turn out to have an older pedigree: domain restriction, set subtraction and intersection. All signatures considered include domain restriction, at least as a term. Combinations of the operations are classified and given complete axiomatizations with and (...) without the presence of functional composition. Each classification is achieved by way of providing a concrete representation of the corresponding abstract algebras as partial maps acting on special kinds of filters determined with respect to various induced orders. In contrast to many negative results in the broader area, all of the considered combinations lead to finite axiomatizations. (shrink)
