This book presents a new nominalistic philosophy of mathematics: semantic conventionalism. Its central thesis is that mathematics should be founded on the human ability to create language – and specifically, the ability to institute conventions for the truth conditions of sentences. This philosophical stance leads to an alternative way of practicing mathematics: instead of “building” objects out of sets, a mathematician should introduce new syntactical sentence types, together with their truth conditions, as he or she develops a theory. Semantic conventionalism (...) is justified first through criticism of Cantorian set theory, intuitionism, logicism, and predicativism; then on its own terms; and finally, exemplified by a detailed reconstruction of arithmetic and real analysis. Also included is a simple solution to the liar paradox and the other paradoxes that have traditionally been recognized as semantic. And since it is argued that mathematics is semantics, this solution also applies to Russell’s paradox and the other mathematical paradoxes of self-reference. In addition to philosophers who care about the metaphysics and epistemology of mathematics or the paradoxes of self-reference, this book should appeal to mathematicians interested in alternative approaches.

A method of supervaluation for Kripke’s theory of truth is presented. It differs from Kripke’s own method in that it employs trees; results in a compositional semantics; assigns the intuitively correct truth values to the sentences of a particularly tricky example of Gupta’s; and – it is argued – is acceptable as an explication of the correspondence theory of truth.

A modification of Kripke’s theory of truth is proposed and it is shown how this modification solves some of the problems of expressive weakness in Kripke’s theory. This is accomplished by letting truth values be grounded in facts about other sentences’ ungroundedness.

Two reverse supertasks—one new and one invented by Pérez Laraudogoitia —are discussed. Contra Kerkvliet and Pérez Laraudogoitia, it is argued that these supertasks cannot be used to conduct fair infinite lotteries, i.e., lotteries on the set of natural numbers with a uniform probability distribution. The new supertask involves an infinity of gods who collectively select a natural number by each removing one ball from a collection of initially infinitely many balls in a reverse omega-sequence of actions.

Radical glut and gap theorists deny—in opposite ways—that the liar sentence has exactly one of the two values true and not true. I describe a scenario where a signalman finds himself in a situation analogous to the liar paradox: if he lights a fire at a certain time, that is analogous to the liar being true, and if he does not, that is analogous to the liar not being true. It is obvious that he must make exactly one of those (...) states of affairs come about. It is argued that there are no relevant differences between the liar and the signalman’s dilemma, implying that the glut and gap theorists are wrong about the former. A further point is that whether or not the liar is true/the signalman lights the fire, language/the signalman is misleading relative to the conditions under which the liar/the fire “ought” to be true/lit.

In this paper it is argued that the understanding of Brouwer as replacing truth conditions with assertability or proof conditions, in particular as codified in the so-called Brouwer-Heyting-Kolmogorov Interpretation, is misleading and conflates a weak and a strong notion of truth that have to be kept apart to understand Brouwer properly: truth-as-anticipation and truth- in-content. These notions are explained, exegetical documentation provided, and semi-formal recursive definitions are given.

To ascertain the rational credences for the epistemic agents in the famous cases of self-locating belief, one should model the processes by which those agents acquire their evidence. This approach, taken by Darren Bradley (Phil. Review 121, 149–177) and Joseph Halpern (Ergo 2, 195–206), is immensely reasonable. Nevertheless, the work of those authors makes it seem as if this approach must lead to such conclusions as the Doomsday argument being correct, and that Sleeping Beauty should be a halfer. I argue (...) that this is due to an implicit existential bias: it is assumed that the first step in those processes is the determination that the agent in question must necessarily exist. It is much more reasonable to model that determination as contingent and a result of other, earlier, steps in the process. This paper offers such alternative models. They imply an endorsement of what has mockingly been called “presumptuous” reasoning, and a massive shift of credences in favor of (1) the existence of a multiverse and (2) the Everettian interpretation of quantum mechanics.

According to L.E.J. Brouwer, there is room for non-definable real numbers within the intuitionistic ontology of mental constructions. That room is allegedly provided by freely proceeding choice sequences, i.e., sequences created by repeated free choices of elements by a creating subject in a potentially infinite process. Through an analysis of the constitution of choice sequences, this paper argues against Brouwer’s claim.

This paper describes a scenario in which a person in his afterlife will with probability 1 spend twice as many days in Heaven as in Hell, but, even though Heaven is as good as Hell is bad, his expected utility for any given day in that afterlife is negative.

The main conclusion is this conditional: If the principle of reflection is a valid constraint on rational credences, then it is not rational to have a uniform credence distribution on a countable outcome space. The argument is a variation on some arguments that are already in the literature, but with crucial differences. The conditional can be used for either a modus ponens or a modus tollens; some reasons for thinking that the former is most reasonable are given.

In 1964 José Benardete invented the “New Zeno Paradox” about an infinity of gods trying to prevent a traveller from reaching his destination. In this paper it is argued, contra Priest and Yablo, that the paradox must be resolved by rejecting the possibility of actual infinity. Further, it is shown that this paradox has the same logical form as Yablo’s Paradox. It is suggested that constructivism can serve as the basis of a common solution to New Zeno and the paradoxes (...) of truth, and a constructivist interpretation of Kripke’s theory of truth is given.

This paper describes a way of defending a modification of Eckhardt's [2013] solution to the Two Envelopes Paradox. The defence is based on ideas from Arntzenius, Elga, and Hawthorne [2004].

Lasersohn has argued that the use of Russell's analysis of the definite determiner in Montague Grammar, which is responsible for giving the correct prediction in the case of the Temperature Paradox, is also responsible for giving the wrong prediction in the case of the Gupta Syllogism. In this paper I argue against Lasersohn, and show that the problem of the Gupta Syllogism can be solved by making a minor addition to Intensional Montague Grammar. This solution is one that Lasersohn discusses (...) but rejects. I will show that his critique of it is ill-founded. (shrink)

This paper offers a unification and systematization of the grounding approaches to truth, denotation, classes and abstraction. Its main innovation is a method for “kleenifying” bivalent semantics so as to ensure that the trivalent semantics used for various linguistic elements are perfectly analogous to the semantics used by Kripke, rather than relying on intuition to achieve similarity. The focus is on generalizing strong Kleene semantics, but one section is devoted to supervaluation, and the unification method also extends to weak Kleene (...) semantics. (shrink)

This volume outlines a Deleuzian approach to analyzing science, culture and politics.

The aim of this essay is to reflect on the place and importance of the question of address and to show how it comes to the fore in Søren Kierkegaard’s writings. What shall be attempted, with regard to Kierkegaard’s already widely recognized renown as an existential thinker, is to catch a glimpse of issues that make up the larger background in which the question of address is embedded. In doing so, the essay explores several features of Kierkegaard’s inquiry into the (...) question of existence in the Concluding Unscientific Postscript and connect them with the notion of the reader. This latter notion provides a way of understanding the singularity of voice, while offering an account of the testimony to existence. After a brief recapitulation, the essay identifies in conclusion unresolved issues relating to speech, silence, confidentiality, and listening. (shrink)

We review some of the main implications of the free-energy principle (FEP) for the study of the self-organization of living systems – and how the FEP can help us to understand (and model) biotic self-organization across the many temporal and spatial scales over which life exists. In order to maintain its integrity as a bounded system, any biological system - from single cells to complex organisms and societies - has to limit the disorder or dispersion (i.e., the long-run entropy) of (...) its constituent states. We review how this can be achieved by living systems that minimize their variational free energy. Variational free energy is an information theoretic construct, originally introduced into theoretical neuroscience and biology to explain perception, action, and learning. It has since been extended to explain the evolution, development, form, and function of entire organisms, providing a principled model of biotic self-organization and autopoiesis. It has provided insights into biological systems across spatiotemporal scales, ranging from microscales (e.g., sub- and multicellular dynamics), to intermediate scales (e.g., groups of interacting animals and culture), through to macroscale phenomena (the evolution of entire species). A crucial corollary of the FEP is that an organism just is (i.e., embodies or entails) an implicit model of its environment. As such, organisms come to embody causal relationships of their ecological niche, which, in turn, is influenced by their resulting behaviors. Crucially, free-energy minimization can be shown to be equivalent to the maximization of Bayesian model evidence. This allows us to cast natural selection in terms of Bayesian model selection, providing a robust theoretical account of how organisms come to match or accommodate the spatiotemporal complexity of their surrounding niche. In line with the theme of this volume; namely, biological complexity and self-organization, this chapter will examine a variational approach to self-organization across multiple dynamical scales.

This volume assembles supporters and critics of situated cognition research to evaluate the intricacies, prerequisites, possibilities, and scope of a 4E methodology. The contributions are divided into three categories. The first category entails papers dealing with a 4E methodology from the perspective of epistemology and philosophy of science. It discusses whether to support explanatory pluralism or explanatory unification and focuses on possible compromises between ecological psychology and enactivism. The second category addresses ontological questions regarding the synchronic and diachronic constitution of (...) cognitive phenomena, the localization of cognitive processes, and the theoretical issue of mutual manipulability. The third category analyzes how the theoretical and practical commitments of 4E approaches lead to empirically supported investigations of different phenomena, such as research on affordances and (chronic) pain. The book renews attention to the possible adverse consequences coming along with methodical fragmentation, as found among 4E positions. It provides an overdue first step towards a systematic and positive answer to methodological concerns in situated cognition research. Without this and further steps in the future, the growth of 4E ́s significance for the scientific study of the mind might stall or even decrease. With such steps, situated cognition research could realize its frequently highlighted but so far not comprehensively accessed potential to change radically the modalities of how cognitive phenomena are studied. This volume is of interest to scholars of the philosophy of mind. (shrink)

Die philosophische Rede von der Schuld umgreift ein breites Bedeutungsspektrum, von der Existenz- und Religionsphilosophie bis zur Ästhetik. Hegel bestimmt den Begriff der Schuld jedoch vornehmlich im Zusammenhang seiner Lehre von der Handlung als einem konstitutiven Bestandteil seiner Moralitätskonzeption. Zentraler Gegenstand dieser Untersuchung sind deshalb Hegels Grundlinien der Philosophie des Rechts; sie bezieht jedoch auch handlungstheoretische Aspekte der Phänomenologie des Geistes, der Vorlesungen über die Philosophie der Weltgeschichte sowie der Wissenschaft der Logik ein. Die Auseinandersetzung mit dem von Hegel begründeten (...) und mit seiner Schuld- und Strafkonzeption untrennbar verwobenen Begriff der Handlung erfolgt jedoch nicht im rein philosophiehistorischen Interesse, sondern sie erweist Hegels Handlungskonzeption mit Blick auf aktuelle Diskussionen innerhalb der Rechtswissenschaft als bedeutenden historisch-systematischen Bezugspunkt sowie als mitunter notwendiges Korrektiv."--Publisher's website.

This essay aims to outline in what ways Kierkegaard’s thinking of existence not only brings into view a concept of existence, but, more fundamentally, enables one to locate an opening to questioning anew the relation of thinking and existence. This thinking of existence does not seek to dissolve existence into knowledge but aims at intensifying the question of a thinking grounded not in the conclusion made in “an external relation between a knower and a non-knower” of which non-knowledge is the (...) negative determination of knowledge, but rather of a thinking grounded in existence.

Based upon a brief outline of existential-phenomenological ontology we present a theoretical and practical understanding of humanbeing, which is suited for a methodologically reflected approach to qualitative research. We present the phenomenological distinction between threedimensions of corporeal intentionality(structural, generative and dialectic intentionality) that form elementary events and structures of meaning. Various aspects of human being are better scrutinized with these concepts of intentionality, such as the association of individual being or collective being (e.g. groups) with the less differentiated anonymity of (...) human being. The aim of our framework is to support the qualitative researcher in grasping the experience of the human life in closer accord with how this being actually unfolds and is lived. Application of the presented framework is illuminated with empirical examples from educational, health and psychological contexts. Finally, we discuss the methodological implications that our approach has for qualitative investigations of human being. (shrink)

In this essay I will examine the various ways in which the concept of decision emerges in the writings of Kierkegaard focusing mainly on the Philosophical Fragments and the Postscript. This prepares the way for revisiting Kierkegaard’s concept of decision. Doing so indicates the radical way in which Kierkegaard connects the concept of decision to an aporia. The crucial existential concept of decision not only concerns the difficulty, or even the impasse, pertaining to knowledge, but also relates to the question (...) of how the singular finds his or her own way through existence.

Hannah Arendt’s concept of the mob has long been neglected. This paper aims to shine new light on the concept. It focusses on the mob’s role in Origins of Totalitarianism, as one of the key components in the rise of totalitarianism. First, this paper analyses Arendt’s definition of the mob. Next, it traces the mob’s origins, its growing influence, and two major ideological predispositions: tribal nationalism and rebellious nihilism. After further differentiation from Arendt’s concept of the masses, using the concept (...) of the mob, the paper counters Robert Paxton’s objection to theories of atomized societies leading to fascism.

The book consists of three problem areas which are all connected with the question of creativity, esp. in gthe arts and poetry: It is about the ancient mythopoetic concept of the muses and their collision with the beloved of the poet, about the authority crisis of authorship and the dominance of the author over his creatures and fictional characters as well as their revolt against the father of the text and about a typ of creating and writing which acts against (...) all genetic traditions of authorship in the form of conception and birth, genealogical derivation. In this sense the, anti-generic' creativity doesn't originate and invent a work of art or a cultural phenomenon: the anti-generic product is something made, something constructed and not fgenerated, manufactured and not breed. This anti-oedupus-concept workts in a widespread tradition of the arts and literature, starting from our heroes of deconstructed narrative as Sterne's or Diderot's, over the classics of european realism Dostoevski or Flaubert until Nabokov and his, pregnant muse' Lolita. Wenn es ums Schaffen geht oder gar ums Schöpferische, liegt nichts so nahe wie das scheinbar unerschöpfliche Feld der Geburtsmetaphern, das Reden vom Zeugen und Empfangen, vom Austragen und Gebären eines Werkes, das für das Kind steht - ja dieses gar ersetzen soll. Die in diesem Band versammelten Überlegungen verknüpfen drei Problemkreise: Es geht um die Projektionsfigur der Musen und ihrer Kollision mit der Dichtergeliebten, um die permanente Autoritätskrise im Verhältnis des Autors zu seinen eigenen Geschöpfen und um die Entdeckung eines Kunstschaffens und Schreibens, das alle genetischen wie generischen Modi der Hervorbringung gegen den Strich dichtet und also konsequent antigenerisch verfährt. Vorgeführt werden diese drei Problemkreise an klassischen Texten des antigenerischen. Zuletzt bleibt die Frage nach den Musen der Musen und den Paradoxa der Dame Dichterin mit Blick auf ihre Inspirationsquellen. (shrink)

Although written more than 2,500 years ago and within a radically different culture, the Tao Te Ching's concepts and teachings have become more influential in the West than ever before. Laozi, the Chinese sage and founder of Taoism, sets out a path (tao) that allows us to tune in to the nature of the universe. His axioms are intended to help us achieve transcendence and a life of integrity and balance: they explore the importance of male and female complementary qualities (...) while praising self-knowledge and criticizing rational understanding. Among his insights are the beliefs that flexibility and suppleness are superior to rigidity and strength, and that self-absorption and self-importance are vain and destructive. This illustrated edition of a classic work is an essential addition to any home library of the world's classic philosophical texts. (shrink)

ABSTRACT If phenomenology is a research methodology uniquely positioned to enable us to learn from others, I aim to demonstrate the idea that cinema is a privileged site from which to investigate the notion of virtuality (sight and reality), even in an age where vision’s predominance is waning. In order to do so, I consider the painfully disruptive mother-daughter relationship found cross-culturally and discourse-analytically in contemporary patriarchal societies. This bond is arguably of central concern to feminists (and women in general) (...) since previous research has found that the fractious nature of this dynamic points to a very specific psychological deformation of the female psyche under conditions of sexist oppression. The views of French psychoanalyst and philosopher Julia Kristeva and other feminist contributors to the debate on this psychological construct are considered. The possibility of a cultural remedy inspired by a secularised trend of Chinese Buddhism in post-Maoist China, a society very different from that of the West, is investigated. This will involve the analysis of the film Curse of the Golden Flower (Chinese Mandarin soundtrack and English subtitles). I subsequently explore whether or not a valuable model for the compromised mother/daughter relationship is available within the context of the notion of a “slave economy” in the comparatively healthier mother/son relationship of (contemporary) Han Chinese culture. By means of cross-cultural analysis as research tool, this article finds confirmation for the proposition of a positive mother/daughter dynamic in the French novelist Colette’s relationship with her mother, Sido. In conclusion, I find that cinema (as an art form serving the eye, i.e. virtuality) is particularly well suited as a site to investigate psychological phenomena by way of interpretative phenomenology as a research methodology, even as vision – as the human sense of choice – has begun to wane amid a global crisis in masculinity.

Gilles de la Tourette syndrome (TS) is a childhood neuropsychiatric disorder characterised by the presence of motor and vocal tics. Patients with malignant TS experience severe disease sequelae; risking morbidity and mortality due to tics, self-harm, psychiatric comorbidities and suicide. By definition, those cases termed ‘malignant’ are refractory to all conventional psychiatric and pharmacological regimens. In these instances, deep brain stimulation (DBS) may be efficacious. Current 2015 guidelines recommend a 6-month period absent of suicidal ideation before DBS is offered to (...) patients with TS. We therefore wondered whether it may be ethically justifiable to offer DBS to a minor with malignant TS. We begin with a discussion of non-maleficence and beneficence. New evidence suggests that suicide risk in young patients with TS has been underestimated. In turn, DBS may represent an invaluable opportunity for children with malignant TS to secure future safety, independence and fulfilment. Postponing treatment is associated with additional risks. Ultimately, we assert this unique risk-benefit calculus justifies offering DBS to paediatric patients with malignant TS. A multidisciplinary team of clinicians must determine whether DBS is in the best interest of their individual patients. We conclude with a suggestion for future TS-DBS guidelines regarding suicidal ideation. The importance of informed consent and assent is underscored. (shrink)

La science du bien et du mal n'a jamais existé, et si Platon s'en désolait, nous avons cessé, nous, les Modernes, de nous en offusquer. Et pourtant, des questions d'ordre éthique nous sont incessamment posées aujourd'hui, ni plus ni moins que par le passé: quelles valeurs morales devons-nous promouvoir à l'école? Est-il acceptable d'abandonner à leur sort les familles de migrants fuyant la guerre? Notre pays, la France, doit-il intervenir militairement contre tel ou tel État dit "terroriste"?, etc. Face à (...) de telles interrogations, nous ne pouvons nous contenter de suspendre notre jugement sous couvert de relativisme ("À chacun sa conception du bien et du mal"). Prenant appui sur les réflexions de grands philosophes et théologiens face au défi du mal, tout en interrogeant la montée de nouvelles formes de violences au XXIe siècle, Laurence Hansen-Love pose la question: le bien et le mal sont-ils vraiment des notions obsolètes? Une fois récusée la fausse évidence d'une symétrie entre le bien et le mal, il est possible de prendre acte de la préséance du mal sur le bien. Dès lors, la certitude du mal, posée comme un fait, cesse de contredire l'incertitude du bien, à laquelle il apparaît sage de se résoudre."--Page 4 of cover. (shrink)

After explaining the well-known two-envelope paradox by indicating the fallacy involved, we consider the two-envelope problem of evaluating the factual information provided to us in the form of the value contained by the envelope chosen first. We try to provide a synthesis of contributions from economy, psychology, logic, probability theory (in the form of Bayesian statistics), mathematical statistics (in the form of a decision-theoretic approach) and game theory. We conclude that the two-envelope problem does not allow a satisfactory solution. An (...) interpretation is made for statistical science at large. (shrink)
