We model scientific theories as Bayesian networks. Nodes carry credences and function as abstract representations of propositions within the structure. Directed links carry conditional probabilities and represent connections between those propositions. Updating is Bayesian across the network as a whole. The impact of evidence at one point within a scientific theory can have a very different impact on the network than does evidence of the same strength at a different point. A Bayesian model allows us to envisage and analyze the (...) differential impact of evidence and credence change at different points within a single network and across different theoretical structures.

Our scientific theories, like our cognitive structures in general, consist of propositions linked by evidential, explanatory, probabilistic, and logical connections. Those theoretical webs ‘impinge on the world at their edges,’ subject to a continuing barrage of incoming evidence. Our credences in the various elements of those structures change in response to that continuing barrage of evidence, as do the perceived connections between them. Here we model scientific theories as Bayesian nets, with credences at nodes and conditional links between them modelled (...) as conditional probabilities. We update those networks, in terms of both credences at nodes and conditional probabilities at links, through a temporal barrage of random incoming evidence. Robust patterns of punctuated equilibrium, suggestive of ‘normal science’ alternating with ‘paradigm shifts,’ emerge prominently in that change dynamics. The suggestion is that at least some of the phenomena at the core of the Kuhnian tradition are predictable in the typical dynamics of scientific theory change captured as Bayesian nets under even a random evidence barrage.

The rise of appeals to intuitive theories in many areas of cognitive science must cope with a powerful fact. People understand the workings of the world around them in far less detail than they think. This illusion of knowledge depth has been uncovered in a series of recent studies and is caused by several distinctive properties of explanatory understanding not found in other forms of knowledge. Other experimental work has shown that people do have skeletal frameworks of expectations that constrain (...) richer ad hoc theory construction on the fly. These frameworks are supplemented by an ability to evaluate and rely on the division of cognitive labour in one's culture, an ability shown to be present even in young children. (shrink)

The immediate successors of Kant in classical German philosophy considered a subjectivity irreducible to objecthood as the core of personhood. The thesis of an irreducible subjectivity has, after the German idealists, been advocated by the phenomenological movement, as well as by analytical philosophers of self-consciousness such as Hector-Neri Castaneda and Sydney Shoemaker. Their arguments together show that self-consciousness cannot be reduced to a relation whereby a subject grasps itself as an object, but that there must be a core of subjectivity (...) always already familiar with itself before reflection. A number of contemporary accounts of self-consciousness are unaware of these old and new arguments, and flawed in that they do not account for the core 'non-objectal subjectivity' necessary for self-consciousness and.

According to the so-called metaphysical conception of analyticity, analytic truths are true in virtue of meaning (or content) alone and independently of (extralinguistic) facts. Quine and Boghossian have tried to present a conclusive argument against the metaphysical conception of analyticity. In effect, they tried to show that the metaphysical conception inevitably leads into a highly implausible view about the truthmakers of analytic truths. We would like to show that their argument fails, since it relies on an ambiguity of the notion (...) of 'independence of (extralinguistic) facts'. If one distinguishes between variation independence and existence independence, the unwelcome view about the truthmakers of analytic truths no longer follows. Thus, there is at best a challenge, but no conclusive argument. The door to the metaphysical conception of analyticity is still open. (shrink)

The topic of homonymy, especially the variety of homonymy that has gone under the title, “focal meaning,” is of fundamental importance to large portions of Aristotle’s work-not to mention its central place in the ongoing controversies between Aristotle and Plato. It is quite astonishing, therefore, that the topic should have gone so long without a book-length treatment. And it is all the more gratifying that the new book on homonymy by Christopher Shields should be so comprehensive, and of such uniformly (...) high quality.’ Everyone who cares about Aristotle will be in his debt. Shields’s book falls into two parts. In the first, he is concerned to lay out the basic structure of Aristotle’s views about homonymy; in the second part, we are led through the various applications of the idea, to the analysis of friendship, for example, the homonymy of the body, the account of goodness and, not least, the homonymy of being. Shields’s book brings out well how the topic of homonymy weaves in and out of the fabric of Aristotle’s thinking in a variety of areas. I will resist the temptation to follow Shields through these various subject-matters, and instead take up essentially two topics. First, (I), the basic outline of Aristotle’s notion of homonymy, more or less independently of its different applications (here, I follow Shields’s example in the first half of his book). Thereafter, I discuss a single application: the homonymy of being (this is the subject of Shields’s last and longest chapter). Here, I will be interested (II) in how homonymy relates to the theory of the categories; and (III) in the application of homonymy to the analysis of substance in the Metaphysics. (shrink)

Frank E. Zachos offers a comprehensive review of one of today's most important and contentious issues in biology: the species problem. After setting the stage with key background information on the topic, the book provides a brief history of species concepts from antiquity to the Modern Synthesis, followed by a discussion of the ontological status of species with a focus on the individuality thesis and potential means of reconciling it with other philosophical approaches. More than 30 different species concepts (...) found in the literature are presented in an annotated list, and the most important ones, including the Biological, Genetic, Evolutionary and different versions of the Phylogenetic Species Concept, are discussed in more detail. Specific questions addressed include the problem of asexual and prokaryotic species, intraspecific categories like subspecies and Evolutionarily Significant Units, and a potential solution to the species problem based on a hierarchical approach that distinguishes between ontological and operational species concepts. A full chapter is dedicated to the challenge of delimiting species by means of a discrete taxonomy in a continuous world of inherently fuzzy boundaries. Further, the book outlines the practical ramifications for ecology and evolutionary biology of how we define the species category, highlighting the danger of an apples and oranges problem if what we subsume under the same name ("species") is in actuality a variety of different entities. A succinct summary chapter, glossary and annotated list of references round out the coverage, making the book essential reading for all biologists looking for an accessible introduction to the historical, philosophical and practical dimensions of the species problem.

The assumption of domain specificity has been invaluable to the study of the emergence of biological thought in young children. Yet, domains of thought must be understood within a broader context that explains how those domains relate to the surrounding cultures, to different kinds of cognitive constraints, to framing effects, to abilities to evaluate knowledge and to the ways in which domain-specific knowledge in any individual mind is related to knowledge in other minds. All of these issues must come together (...) to have a full account of conceptual development in biology. (shrink)

The standard rationality hypothesis implies that behaviour can be represented as the maximization of a suitably restricted utility function. This hypothesis lies at the heart of a large body of recent work in economics, of course, but also in political science, ethics, and other major branches of social sciences. Though the utility maximization hypothesis is venerable, it remains an area of active research. Moreover, some fundamental conceptual problems remain unresolved, or at best have resolutions that are too recent to have (...) achieved widespread understanding among social scientists. The main purpose of the Handbook of Utility Theory is to make recent developments in the area more accessible. The editors selected a number of specific topics, and invited contributions from researchers whose work had come to their attention. Therefore, the list of topics and contributions is largely the editors' responsibility. Each contributor's chapter has been refereed, and revised according to the referees' remarks. This is the first volume of a two volume set, with the second volume focusing on extensions of utility theory. (shrink)

The aim of this paper is to argue that update semantics is a natural framework for contextually restricted quantification, and to illustrate its use in the analysis of anaphoric definite descriptions and certain other anaphoric terms.

The more carefully we look, the more impressive the repertoire of infant concepts seems to be. Across a wide range of tasks, infants seem to be using concepts corresponding to surprisingly high-level and abstract categories and relations. It is tempting to try to explain these abilities in terms of a core capacity in spatial cognition that emerges very early in development and then gets extended beyond reasoning about direct spatial arrays and events. Although such a spatial cognitive capacity may indeed (...) form one valuable basis for later cognitive growth, it seems unlikely that it can be the sole or even primary explanation for either the impressive conceptual capacities of infants or the ways in which concepts develop.

A brief review is given of the continuous spontaneous localization (CSL) model, in which a classical field interacts with quantized particles to cause dynamical wavefunction collapse. One of the model's predictions is that particles “spontaneously” gain energy at a slow rate. When applied to the excitation of a nucleon in a Ge nucleus, it is shown how a limit on the relative collapse rates of neutron and proton can be obtained, and a rough estimate is made from data. When applied (...) to the spontaneous excitation of 1s electrons in Ge, by a more detailed analysis of more accurate data than given previously, an updated limit is obtained on the relative collapse rates of the electron and proton, suggesting that the coupling of the field to electrons and nucleons is mass proportional.

The COVID-19 pandemic created a situation for the implementation of emergency remote learning. This meant that as a lecturer at a traditionalist University of contact sessions, the pandemic forced us to teach remotely through online methods of communication, using online lectures, narrated powerpoints, voice clips, podcasts, interviews and interactive videos. The assessments were conducted online from assignments to multiple choice questions, which forced the lecturers to think differently about the way the assessments were presented, in order to avoid easy access (...) to answers found in a textbook and online. This meant that more application questions of theory to practice were assessed in a more challenging way to prevent cheating and collaboration with peers. Formal assessments completed during emergency remote learning, have become the past practice, as innovative methods have been adopted for learning and for assessment purposes in order to preserve the integrity and attainment of the degree through online modes of learning. The aim of the paper investigates and explores the methods of teaching, together with the results obtained from the students of 2019 and 2020 in their final year relating to two final year modules against the literature relating to learning processes and methodologies.

"Good Taste, Bad Taste, and Christian Taste is essential reading for students and scholars of religion and theology, pastors and church-goers, liturgists, and church musicians and artists."--Jacket.

In 1952, Quine showed that the problem of reducing a propositional formula to a simplest normal equivalent can be solved in two steps, viz., (i) express the given formula, Φ, equivalently as the disjunction of all its prime implicants, and (ii) find all non-redundant disjunctions of the latter that are equivalent to Φ (Quine 1952). However, it seems not generally known that an ingenious form of the same two-step process was published by Hugh McColl in 1878.

Perfect for use at advanced undergraduate and graduate level, this is the first text to offer students a unified narrative regarding the place of the body in Western thinking. The body is simultaneously active and passive, powerful and vulnerable and as such, it fundamentally informs ontological, political, ethical and epistemological issues.

This essay argues that the deontological view of morality is connected to extreme and massive forms of violence through a kind of phenomenological necessity. In the first main section, I examine one family of such violence, which usually comes under the label of “religious violence”. I argue that it is not the religious element but the disqualification of context from the realm of justification which characterizes such violence. In the second main section, I examine the phenomenology of duty to conclude (...) that duty, by definition, denies any normative relevance to context. In the third main section, I use this sketch of a phenomenology of duty to propose a hypothesis about the underpinnings of the connection between mass violence and duty, namely, that the notion of duty carries with it the exclusion of moderation, and places the agent before an impossible situation that can only be resolved by violence.

I take the phrase ‘congenital transcendentalism’ from Santayana who defined it as ‘the spontaneous feeling that life is a dream’. ‘The loneliness which is the truth about things’ is a phrase of Virginia Woolf's. The thesis I will advance is that many expressions of doubt or denial of the shareable world are self-misunderstood manifestations of the state indicated by Woolf's expression. But the loneliness of which Woolf speaks must not be construed as the kind of loneliness which can be assuaged (...) by family, friends, lovers or company. Nor is it the loneliness which a convinced solipsist might experience. It is rather the loneliness of ‘that “I” and that “life of mine'” which is ‘untouched whichever way the issue is decided whether the world is or is not’. (shrink)

Der Übergang vom Verhältnisbewußtsein zum Selbstbewußtsein kann unmöglich nur vom Verhältnisbewußtsein aus gedacht werden, weil wir uns eine Welt, in der das Bewubtsein unserer selbst verteilt ist auf die Dimensionen der Handlung vor deren Zentrierung in uns, gar nicht vorstellen können. Jedes Tableau der Handlungsmöglichkeiten, so abstrakt es auch abgefaßt sein mag, ist gebunden an Vorstellungen möglicher Handlungssubjekte, denen wir Handlungsmöglichkeiten zuschreiben. Handlungstheorie ist daher notwendig Reflexion unserer Praxis, in der wir uns selbst als Selbstbewußtsein erfahren, das seinem Verhältnisbewubtsein enthoben (...) ist, ohne dieses dadurch selbst schon aufzuheben zu können. Daß uns Freiheit im Handeln unaufhebbar prekär und problematisch bleiben mub, ist die Grundvoraussetzung dafür, dab wir Handlungstheorien historisch und bereichsbezogen ständig neu entwerfen müssen. Das Verhältnis von Handlungsphilosophie zu Handlungstheorien kann daher so gefaßt werden, daß Handlungsphilosophie die Grundbegrifflichkeit in kritischer Absicht bereitstellt, die den bereichsorientierten, mehr oder weniger deskriptiven Handlungstheorien abgehen muß. Dazu muß die ontologische Differenz von Handlung und Interpretation methodologisch ernst genommen werden. Die radikale Andersheit der hier zu begründenden Konzeption liegt vor allem in der Ansicht, daß Handlungen nicht als isolierbare Ereignis-Entitäten aufgefaßt werden können, die gegenüber der »Welt der Tatsachen des Bewußtseins« eine kausale, d.h. von der Welt des Bewußtseins abgetrennte Rolle übernehmen.

In this paper we investigate those extensions of the bimodal provability logic ${\vec CSM}_{0}$ (alias ${\vec PRL}_{1}$ or ${\vec F}^{-})$ which are subframe logics, i.e. whose general frames are closed under a certain type of substructures. Most bimodal provability logics are in this class. The main result states that all finitely axiomatizable subframe logics containing ${\vec CSM}_{0}$ are decidable. We note that, as a rule, interesting systems in this class do not have the finite model property and are not even (...) complete with respect to Kripke semantics. (shrink)

Operators which map subsets of a given set to the set of their minimal elements with respect to some relation R form the basis of a semanticapproach in non-monotonic logic, belief revision, conditional logic and updating. In this paper we investigate operators of this type from an algebraicviewpoint. A representation theorem is proved and various properties of theresulting algebras are investigated. It is shown that they behave quite differently from known algebras related to logics, e.g. modal algebras and Heytingalgebras.

This article gives a survey of the position of migrant workers in the Belgian labor market and social security system. Total employment of migrants has increased from 114,000 in 1954 to 224,900 in 1970.In contrast to overall employment in the Belgian economy, it went on climbing till 1978, up to a 245,900 level. Beyond this year, forecasts point at a slight decrease. Since WWII, the gravity point of the sectoral division of migrant workers has shifted from minig and industry, to (...) industry and tertiary activities. The share of industry in the employment of migrants bas remained relatively stable, in contrast to the tertiary sector, that witnessed a considerable expansion. However, the latter has not contributed substantially to the quality level of the average guest worker's job.On the whole, there is a strong correspondence between the unstable position of migrants in the labor market and their demographic characteristics on one side, their participation in the social security system on the other side. Their young family structure is reflected in a high share in family allowances and a limited appeal to pension funds. Statistical analysis at the aggregate level does not point at discriminatory practices vis-à-vis migrants and their families in social security ; but at thedisaggregate level and through the inspection of laws, regulations and international conventions, it appears that non-EEC nationals, with an unstable professional career, do not have the same rights as Belgians or EEC-citizens having a confortable position in the labor market and the social security system. In order to guarantee the rights of the farmer, the author suggests to establish a citizenship entitling to full social security rights after five years of regular residence in Belgium. (shrink)

In the three published volumes of his History of Sexuality Foucault reflects on themes of anxiety situated in the Christian doctrine of the flesh that led to a pastoral ministry establishing the rules of a general social economy—rules that enabled, over time, a discourse on the flesh that took thrift, prudence, modesty, and suspicion as essential ethical premises in the emerging “art of the self.” Rather than sensing flesh as a charged, motile potentiality of attachment and intimacy, it came to (...) be seen as skin—as the limit of a sovereign body, embedding guilt and shame into the texture of its expression. This essay pursues the psychological and communication problematic of intimacy as a critical and developmental experience of the flesh. Foucault's concept of self-care and parrhesia, Merleau-Ponty's concept of flesh and embodiment, and Bataille's concept of glory and eroticism contribute to a phenomenology of human development that seeks to articulate an idea of a self diffierentiated from the unspoken binds of familial anxiety and emotionality.
