We prove that superhigh sets can be jump traceable, answering a question of Cole and Simpson. On the other hand, we show that such sets cannot be weakly 2-random. We also study the class $superhigh^\diamond$ and show that it contains some, but not all, of the noncomputable K-trivial sets.

Call generalism about children’s and adults’ wellbeing the thesis that the same theory of wellbeing applies to both children and adults. Our goal is to examine whether generalism is true. While this question has not received much attention in the past, it has recently been suggested that generalism is likely to be false and that we need to elaborate different theories of children’s and adults’ wellbeing. In this paper, we defend generalism against the main objections it faces and make a (...) positive case for it. (shrink)

Kant is well known for his criticism of knowledge claims of traditional metaphysics. The concept of substance must be considered one of the most important notions in ontology. Kant transforms traditional ontology into an analytic of pure understanding. Accordingly, the concept of substance has become a category of pure understanding. The application of this category in the First Analogy of Experience faces some particular problems, which are highlighted in the current debate. This paper seeks to furnish a coherent reading of (...) the First Analogy by considering which purpose the category of substance is meant to serve in transcendental idealism. (shrink)

How many factors, i.e. departures from normality, are necessary to explain a delusion? Maher’s classic one-factor theory argues that the only factor is the patient’s anomalous experience, and a delusion arises as a normal explanation of this experience. The more recent two-factor theory, on the other hand, contends that a second factor is also needed, with reasoning abnormality being a potential candidate, and a delusion arises as an abnormal explanation of the anomalous experience. In the past few years, although there (...) has been an increasing number of scholars offering a variety of arguments in defence of Maher’s one-factor theory, these arguments have not been adequately addressed by two-factor theorists. This paper aims to address this gap by critically examining the arguments on three crucial issues: the intelligibility of delusions, the dissociation between anomalous experiences and delusions, and the empirical evidence of a second factor. I will argue that the Maherian notion of anomalous experience is not sufficient for explaining delusions and the two-factor theory is on the right track in its search for the missing factor in the aetiology of delusions.

The purpose of this anthology is to bring together in one volume some of the texts published in the series "Werkprofile", which focus on Kant’s relationship to his philosophical contemporaries and predecessors, and to make them accessible to a wider audience in English. In doing so, the volume is aimed at those who have an interest in better understanding the premises of Kant's philosophy, its historical context, and the development of many of Kant’s fundamental ideas. As it is often hard (...) to glean philosophical motivation directly from reading Kant’s texts, understanding Kant’s commitment to answering certain questions and his silence on others, requires a historical approach. This broader purview will also be helpful for grasping deeper systematic questions at work throughout Kant’s philosophy. The anthology thus aims at inviting a more wide-angled view of Kant’s philosophy by focusing on overlooked references and historical figures. Scholarship on these references is still at an early stage, even though important steps have been taken in this direction in recent years. The aim of our volume is to build on this development and to supplement and expand the content of existing research. (shrink)

Die sog. Preisschrift über die Fortschritte der Metaphysik hat in den letzten Jahren überraschend wenig Aufmerksamkeit in der Kantforschung erfahren. Das beginnt sich erst langsam zu ändern, bedingt vor allem durch das Wiedereinsetzen eines allgemeinen Interesses an Metaphysik, aber auch durch die Wiederentdeckung der Einsicht, dass die kantische Philosophie nicht nur ihren Ursprung in der nach-wolffschen Philosophie des 18. Jahrhunderts hat, sondern dass Kant mit seinen Fragestellungen insgesamt dieser philosophischen Strömung sehr viel näher bleibt, als die bislang eher auf die (...) empiristische Tradition hin ausgelegten Interpretationsansätze bemerkt haben. Die Beiträge dieses Bandes thematisieren den metaphysischen Ursprung und die metaphysische Stoßrichtung der kantischen Philosophie. Das geschieht vor allem im Ausgang von und mit Blick auf die kantische Preisschrift, die eine besondere Stellung in Kants Werk einnimmt. Ausgehend von dieser Schrift wird einerseits ein Blick zurück auf die Entwicklung der kritischen Philosophie sowie deren Architektonik in Abgrenzung zur rationalistischen Schulphilosophie geworfen und andererseits ein Blick nach vorn zur vermeintlich nachkritischen Revision der Systematik im Opus postumum.

Die Zurückweisung, mit der viele frühneuzeitliche Autoren der aristotelischen Naturphilosophie begegnen, geht häufig mit einer emphatischen Aufnahme der hellenistischen Philosophie einher. Vor diesem Hintergrund fragt die vorliegende Untersuchung nach den prinzipiellen Unterschieden zwischen Aristoteles und seinen hellenistischen Nachfolgern. Ausgangspunkt ist die für die aristotelische Philosophie zentrale Analyse des Phänomens der Bewegung.

Dance anthropologists and ethnomusicologists are trained to treat the labels ‘dance’ and ‘music’ with caution, because the terms carry preconceptions that may mask significant aspects of the structured movement/sound systems they study. Yet many talk about ‘the body’ – the medium through which these systems come into being – as something given and ‘true’, without investigating its emic conceptualizations or looking into the implications these may have in terms of how music and dance are experienced. The article investigates the dancing (...) bodies of western ballet dancers and of Tiwi dancers of northern Australia. The latter have an extensive vocabulary for body parts, but no word for ‘body’ as a bounded entity, comparable to the ‘body’ conceptualized by ballet dancers. The article argues that for the Tiwi landscape and human bodies are unavoidably tied together and that the dancers incarnate both land and cosmology. While specific parts have a concrete practical existence, the whole body expands into the landscape so that the landscape becomes flesh. Through the aesthetic transformation of dancing, dancers and land become one, and life is sustained and the land revitalized. (shrink)

Museums are safe spaces for the objects they hold and for the persons that visit them, providing environments that can function in therapeutic ways. Within the wide range of objects, there is enough diversity to help guests discover what similarities they have with others as well as what makes them unique as individuals. Within exhibits, individuals can explore themselves through the reactions they have to particular pieces, through the observation of what holds their attention within the environment, and through the (...) awareness and development of their contemplative mind. Museums can introduce transpersonal information, add information to previous transpersonal experiences, and even promote expanded states of awareness. With direction, guests can use museums to learn about themselves, thus optimizing the therapeutic potentials of these institutions. (shrink)

In order to explain delusional beliefs, one must first consider what factors should be included in a theory of delusion. Unlike a one-factor theory, a two-factor theory of delusion argues that not only anomalous experience (the first factor) but also an impairment of the belief-evaluation system (the second factor) is required. Recently, two-factor theorists have adopted various Bayesian approaches in order to give a more accurate description of delusion formation. By reviewing the progression from a one-factor theory to a two-factor (...) theory, I argue that in light of the second factor’s requirements, different proposed impairments can be unified within a consistent belief-evaluation system. Under this interpretation of the second factor, I further argue that the role of a mechanism responsible for detecting bizarreness is wrongly neglected. I conclude that the second factor is a compound system which consists of differing functional parts, one of which functions to detect bizarreness in different stages of delusion; moreover, I hold that the impairment can be one or several of these functional parts.

Robert Rosen has proposed several characteristics to distinguish “simple” physical systems (or “mechanisms”) from “complex” systems, such as living systems, which he calls “organisms”. The Memory Evolutive Systems (MES) introduced by the authors in preceding papers are shown to provide a mathematical model, based on category theory, which satisfies his characteristics of organisms, in particular the merger of the Aristotelian causes. Moreover they identify the condition for the emergence of objects and systems of increasing complexity. As an application, the cognitive (...) system of an animal is modeled by the “MES of cat-neurons” obtained by successive complexifications of his neural system, in which the emergence of higher order cognitive processes gives support to Mario Bunge’s “emergentist monism.”.

How does it come about that a person akratically believes that P, while at the same time believing that the available evidence speaks against that P? Among the current accounts, Scanlon offers an intuitive suggestion that one’s seeming experience that P may play an important role in the aetiology of their akratic belief that P. However, it turns out to be quite challenging to articulate what the role of seeming experience is. This paper will offer a novel development of Scanlon’s (...) intuitive suggestion, with a focus on clear-eyed epistemic akrasia. I will argue that the primary role of seeming experience is unlikely to act as the subject’s reason or to provide the subject with prima facie justification; instead, based on the recent work in dogmatism and Cartesian clarity, I will propose a causal account, according to which, when it seems clear to the subject that P, the seeming experience may exert a brute causal force to persistently compel the subject to believe that P. This causal account also has the advantage of helping some existing accounts to explain clear-eyed epistemic akrasia. (shrink)

With their landmark architectures, exhibitions and museums of science and technology partake in the spatial inscription of science in twentieth century landscapes. Unlike other beacons of progress, exhibitions and museums of science and technology double up, inside, as material arrangements of objects, visuals and texts aiming to confer meaning onto the modern world. They both embody and seek to order the spectacle of modernity while often being deployed with the aim of promoting particular visions of social and material progress. An (...) approach sensitive to the material, spatial, and experiential dimensions of displaying science and technology suggests that exhibitions and museums were in the twentieth century crucial sites for reflecting upon and promoting particular futures.

During the past 25 years, the words “theory of action” and “agency theory” have become key-terms in a new branch of philosophy. The themes appear to gain a centrality and influence such that one is led to think that they should cover most of philosophy, including the foundation for all of the human sciences. The number of treatises on human action and on philosophical and special-scientific theories of action is staggering. For the most part inspired by analytic philosophy, the new (...) approach threatens to take over that school’s central place on the stage of international philosophical concern. Having ousted theory of science from that position with an avalanche of analytic studies, analytic philosophy, in turn, is now being overrun by philosophy of action as supposedly suitable basis for the sciences.

Two ways of describing a group are considered. 1. A group is finite-automaton presentable if its elements can be represented by strings over a finite alphabet, in such a way that the set of representing strings and the group operation can be recognized by finite automata. 2. An infinite f.g. group is quasi-finitely axiomatizable if there is a description consisting of a single first-order sentence, together with the information that the group is finitely generated. In the first part of the (...) paper we survey examples of FA-presentable groups, but also discuss theorems restricting this class. In the second part, we give examples of quasi-finitely axiomatizable groups, consider the algebraic content of the notion, and compare it to the notion of a group which is a prime model. We also show that if a structure is bi-interpretable in parameters with the ring of integers, then it is prime and quasi-finitely axiomatizable. (shrink)

Biography of Thiện Chiếu, an outstanding Buddhist monk and an intellectual of Vietnam revolution.

Der in Leipzig lehrende Philosoph und Theologe Christian August Crusius (1715-1775) ist bisher vorwiegend im Rahmen der Kant-Forschung berücksichtigt worden. Dabei war Crusius einer der ersten ernstzunehmenden Kritiker der Philosophie von Christian Wolff, der entscheidende Impulse von Christian Thomasius aufgriff, philosophisch vertiefte und bis in die zweite Hälfte des 18. Jahrhunderts wirkungsvoll tradierte. Der Sammelband nimmt die unterschiedlichen Aspekte des philosophischen und theologischen Schaffens von Crusius in den Blick und rekonstruiert die eigenständige Kontur eines Denkers, der einerseits auf allen Gebieten (...) der Philosophie tätig war und andererseits nach seiner Berufung zum Professor der Theologie ausschließlich an seinem theologischen OEuvre arbeitete. Auf der damit greifbaren Spannung zwischen Philosophie und Theologie liegt ein Hauptaugenmerk des interdisziplinären Sammelbandes. (shrink)

Cicero distinguishes between two forms of divination: natural and artificial divination. Most contemporary scholars assume that Cicero presents a Stoic division and some even draw far-reaching conclusions about the scientific status of divination based on this distinction. However, his justification for the division is apparently contradictory and neither fits with Stoic nor Peripatetic claims that are found elsewhere. This paper examines the exact meaning of the division and sheds light on its Stoic and Peripatetic origin. In this way, we will (...) not only be able to better understand the overall argument of Cicero’s De divinatione, but also to assess his real achievement as a philosophical author. (shrink)

This thesis develops a novel framework for explaining delusions. In Chapter 1, I introduce the two fundamental challenges posed by delusions: the evidence challenge lies in explaining the flagrant ways delusions flout evidence; and the specificity challenge lies in explaining the fact that patients’ delusions are often about a few specific themes, and patients rarely have a wide range of delusional or odd beliefs. In Chapter 2, I discuss the strengths and weaknesses of current theories of delusions, which typically appeal (...) to one or both of two factors: anomalous experience and reasoning abnormality. I argue that anomalous experience can help explain the specificity of delusions, but has difficulties in addressing the evidence challenge; reasoning abnormality can help address the evidence challenge, but has difficulties in explaining the specificity of delusions. This suggests that there may be an important factor that has not been captured by current theories of delusions. To search for this missing factor, in Chapter 3, I turn to normal believing. Inspired by the literature on Cartesian clarity and phenomenal dogmatism, I develop a dual-force framework of believing, according to which beliefs can be understood as the results of the interaction between the justificatory force and causal force of evidence and the justificatory force and causal force of clear experience, in which something clearly seems to be so to the subject. This framework suggests that the missing factor may be the clear experience with its distinctive phenomenal clarity that compels assent. In Chapter 4, I return to delusions, and argue that the dualforce framework can help us to get a better grip on some personal descriptions of delusions; make progress in addressing the evidence and specificity challenges of delusions; and shed new light on the underpinnings of delusions. In the end, I conclude with some remaining questions for future study. (shrink)

In this article, we argue that the phenomenon of predation is the source of several problems for Donaldson and Kymlicka's account of our duties towards wild and liminal animals. According to them, humans should adopt a general policy of non-intervention with respect to predatory behaviour involving wild and liminal animals. They justify this recommendation by appealing to the status of those animals as, respectively, members of sovereign communities and denizens of human-animal societies. Our goal is not to question their recommendation, (...) but to challenge the reasons given in its support. On the one hand, we argue that, insofar as wild animal communities are incapable of dealing with massive predation, they do not possess the competence required for sovereignty. Moreover, we argue that, even if we leave the issue of competence aside, attributing sovereignty rights to communities including both predators and preys may not be the best way to protect wild animals’ fundamental interests. On the other hand, we argue that there exist two important disanalogies between human denizens and liminal animals, which render Donaldson and Kymlicka's denizenship framework problematic. We suggest that the ultimate justification for a general policy of non-intervention lies in the significant risk of causing greater harm by acting otherwise, due to our limited knowledge and resources.

In this paper I problematise quite a simple assertion: that the two major frameworks used in assessing consent to post-mortem organ donation, presumed consent and informed consent, are procedurally similar in that both are ‘default rules.’ Because of their procedural common characteristic, both rules do exclude marginalized groups from consent schemes. Yet this connection is often overlooked. Contract theory on default rules, better than bioethical arguments, can assist in choosing between these two rules. Applying contract theory to the question of (...) post-mortem organ donation suggests that the default rule should be one that goes against the wishes of the stronger party in consent decisions.

We describe a strongly minimal theory S in an effective language such that, in the chain of countable models of S, only the second model has a computable presentation. Thus there is a spectrum of an -categorical theory which is neither upward nor downward closed. We also give an upper bound on the complexity of spectra.

Standardly, epistemic peers regarding a given matter are said to be people of equal competence who share all relevant evidence. Alternatively, one can define epistemic peers regarding a given matter as people who are equally likely to be right about that matter. I argue that a definition in terms of likelihood captures the essence of epistemic peerhood better than the standard definition or any variant of it. What is more, a likelihood definition implies the truth of the central thesis in (...) the debate on peer disagreement, the so-called Equal Weight View, according to which we should give the opinions of our peers the same weight we give our own. Adopting a likelihood definition, however, does not end the debate on peer disagreement, because the alleged theoretical alternatives to the Equal Weight View, reinterpreted in the light of a likelihood definition, can in fact be shown to be compatible with this view—though the reinterpreted versions may appear less plausible than the original ones.
