Objective Bayesianism is a methodological theory that is currently applied in statistics, philosophy, artificial intelligence, physics and other sciences. This book develops the formal and philosophical foundations of the theory, at a level accessible to a graduate student with some familiarity with mathematical notation.

While there are several arguments on either side, it is far from clear as to whether or not countable additivity is an acceptable axiom of subjective probability. I focus here on de Finetti's central argument against countable additivity and provide a new Dutch book proof of the principle, To argue that if we accept the Dutch book foundations of subjective probability, countable additivity is an unavoidable constraint.

Bayesian probability is normally defined over a fixed language or eventspace. But in practice language is susceptible to change, and thequestion naturally arises as to how Bayesian degrees of belief shouldchange as language changes. I argue here that this question poses aserious challenge to Bayesianism. The Bayesian may be able to meet thischallenge however, and I outline a practical method for changing degreesof belief over changes in finite propositional languages.

The first aim of this paper is to introduce a new way of looking at supertasks in the light of special relativity which makes use of the elementary dynamics of relativistic point particles subjected to elastic binary collisions and constrained to move unidimensionally. In addition, this will enable us to draw new physical consequences from the possibility of supertasks whose ordinal type is higher than the usual ω or ω * considered so far in the literature. Thus, the paper shows (...) how an entire collection of infinitely many particles may place itself spontaneously in motion (mechanical self-acceleration) or even reach the speed of light in a way compatible with special relativity. Interesting implications for classical mechanics are also derived, particularly the possibility of a system of particles disappearing spontaneously in spatial infinity even under the condition of the non-existence of non-collision singularities.

This paper addresses the question: Who or what can have a moral status in the sense that we have direct moral duties to them? It argues for a biocentric answer which ascribes inherent moral status value to all individual living organisms. This position must be defended against an anthropocentric position. The argument from marginal cases propounded by Tom Regan and Peter Singer for this purpose is criticised as defective, and a different argument is proposed. The biocentric position developed here is (...) related to that of Albert Schweitzer and Paul F. Taylor, but rejects their assumption of equal inherent value for all living organisms. It argues instead for equal moral status value for moral persons and agents, and gradual moral status value for nonpersons, depending on their degree of similarity with moral persons. Mary Ann Warren's recent book on Moral Status is also discussed. The argument is constructed as a casuistic argument, proceeding by analogical extension from persons to non-persons. The meta-ethical question of its pragmatic validity is discussed. (shrink)

This interview with David Kleinberg-Levin, Professor Emeritus in the Department of Philosophy at Northwestern University, concerns his recent trilogy on the promise of happiness in literary language. Kleinberg-Levin discusses the relationship between and among philosophy, phenomenology, and literature. Among others, he addresses questions regarding literature’s ability to offer redemption, its response to suffering and justice, literary gesture, the ethics of narrative logic, and the surface of the text.Cet entretien avec David Kleinberg-Levin, Professeur émérite au département de philosophie de la Northwestern (...)

The article addresses the potential impact of functional brain imaging (functional magnetic resonance imaging and positron-emission tomography) on surrogate end-of-life decision-making in light of varying state-law definitions of consciousness, some of which define awareness behaviorally and others functionally. The article concludes that, in light of admonitions by neuroscientists that functional brain imaging cannot yet replace behavioral evaluation to determine the existence of consciousness, state legislatures, courts and drafters of written advance healthcare directives should consider treating behavior, not function, as the (...) touchstone for end-of-life decision-making.

The Recursive Bayesian Net (RBN) formalism was originally developed for modelling nested causal relationships. In this paper we argue that the formalism can also be applied to modelling the hierarchical structure of mechanisms. The resulting network contains quantitative information about probabilities, as well as qualitative information about mechanistic structure and causal relations. Since information about probabilities, mechanisms and causal relations is vital for prediction, explanation and control respectively, an RBN can be applied to all these tasks. We show in particular (...) how a simple two-level RBN can be used to model a mechanism in cancer science. The higher level of our model contains variables at the clinical level, while the lower level maps the structure of the cell's mechanism for apoptosis. (shrink)

The study begins with the language employed in and the psychological basis of thought experiments as understood by certain medieval Arabic philosophers. It then provides a taxonomy of different kinds of thoughts experiments used in the medieval Islamic world. These include purely fictional thought experiments, idealizations and finally thought experiments using ingenious machines. The study concludes by suggesting that thought experiments provided a halfway house during this period between a staunch rationalism and an emerging empiricism.

Elga : 1–10, 2010) has argued that, even when no particular subjective probability is required by one’s evidence, perfectly rational people will have sharp subjective probabilities. Otherwise, they would be rationally permitted to knowingly turn down some sure gains. I argue that it is likewise true that, even when we do not possess enough practical reasons for a sharp evaluation, perfectly rational people will have sharp subjective values. Those who would be most inclined to reject this argument are those who (...) claim that we are rationally required by either our beliefs that objective values are unsharp or by our own ‘real’ values to have unsharp subjective values. Regarding the former claim, I show that we need not believe that all objective values are sharp to rationally have unsharp subjective values. Regarding the latter claim, I conclude that sharpened subjective values must be ‘real’ because otherwise perfect rationality would be impossible in principle. (shrink)

Sarah McGrath (2008; 2011) argues that, when it comes to our controversial moral views, we have no reason to think we are less likely to be in error than those who disagree with us. I refer to this position as the Moral Peer View (MPV). Under pressure from Nathan King (2011a; 2011b), McGrath admits that the Moral Peer View need not always have been true, though she maintains it is true now. Although King seems to think there should be current (...) counterexamples to the Moral Peer View, he holds back from actually proposing any. I argue that those of us who favor marriage equality and gender equality are currently in a position to reject the Moral Peer View with regard to these issues, and I propose conditions under which people can reasonably take their moral beliefs to be epistemically advantaged. King and McGrath agree that opponents of slavery like William Wilberforce could reasonably believe they enjoyed an epistemic advantage over proponents of slavery, and I suggest that proponents of marriage equality and gender equality might make similar claims. I propose that we can make additional claims to epistemic advantages if we believe that (1) almost everyone that considers the matter admits they are advantages, (2) those who disagree with use would admit they are advantages, and (3) we can give a plausible explanation as to why those that we think are epistemically disadvantaged have not noticed that they are disadvantaged. Finally, I argue that it reasonable to think our controversial beliefs are justified if we can find reasons to think our opponents are mistaken, and do not see similar reasons to think ourselves mistaken. This is a better policy than supposing we are just as prone to make mistakes as our opponents, as the latter is both less defensible in theory, and more likely to stifle intellectual progress.

In the anthropology of Christianity, and more broadly in the anthropology of religion, methodological atheism has foreclosed ethnographic description of God as a social actor. This prohibition is the product of certain ontological presumptions regarding agency, an absence of autonomy of human creations, and a truncated conception of what can be said to exist. Reading Tanya Luhrmann's recent ethnography, When God Talks Back: Understanding the American Evangelical Relationship with God (2012), in light of both the ontological postulates of Object Orientated (...) Ontology and the work of Bruno Latour, this article proposes an ontological framework that makes it is possible to ethnographically describe God as a social actor without adopting methodological theism. This article also notes, however, that the ethnographic description of religious practice, found in studies of the Vineyard denomination such as Luhrmann's, challenge Latour's own account of the difference between science and religions as distinguishable enterprises.

Part I of this paper introduces a range of mechanistic theories of causality, including process theories and the complex-systems theories, and some of the problems they face. Part II argues that while there is a decisive case against a purely mechanistic analysis, a viable theory of causality must incorporate mechanisms as an ingredient, and describes one way of providing an analysis of causality which reaps the rewards of the mechanistic approach without succumbing to its pitfalls.

ABSTRACT This Rejoinder to the comments in the Symposium on my Article focuses on the nature of emotion in general; on specific emotions, notably anger, enthusiasm, and love; and on the relation between emotions and rationality. It also expands on some themes from the Article, notably by providing historical evidence for the claim that enthusiasm can generate inaction-aversion.

This article discusses the effects of the OECD Convention on Combating the Bribery of Foreign Public Officials, which was signed in 1997 and is due to be implemented by the signatory nation‐states this year. The Convention represents the expansion of legal measures to combat the bribery of foreign public officials by individuals or corporations, and it has been accompanied by the Organisation of American States’ Convention Against Corruption. Previously the Foreign Corrupt Practices Act , which applied only to United States (...) individuals or corporations, ‘stood alone in the world as a legal barrier to transnational bribery’ . This article proceeds in stages to evaluate implications of the Convention. Firstly the Convention is placed in the context of the increased focus on transnational business bribery in recent years. Second, the main points of the Convention are outlined. Third, the issues and problems posed by the Convention for business are discussed. Finally some themes regarding enforcement by the relevant authorities are outlined. (shrink)

This article provides an analysis of the transnational spatial politics of activism around lesbian, gay, bisexual, transgender and queer politics in Poland. The authors discuss three key themes that emerged from their empirical research on activism associated with the equality marches in Krakow, Poznan and Warsaw. These are concerned with age and the intergenerational politics of solidarity; the connection between migration and activism, and the use of city-twinning links. The authors argue that research on the spatial politics of activism and (...) social movements can enhance existing understandings of the sustainability of activist struggles for lesbian, gay, bisexual, transgender and queer politics in Poland.

Sometimes, a few philosophers say that the Phenomenology of Edmund Husserl include one insight of the human being, which must not be distinguished from humanism. Husserl tries to understand the essence of the man from the analysis of the acts of knowledge. So, he define him like subject, consciousness, subjectivity or like reason. This subject is trascendental from the real, existing world; he is not absolutely accessible to only as a correlate of conscious acts; and he is still trascendental with (...) regard to the community of subjects. This paper examine the solid contributions to the human being in the Phenomenological method as well his insufficiency. (shrink)

This article argues for the importance of distinguishing the form of a theory of happiness from its content. It applies this distinction to ancient ethics, to show that almost all ancient philosophers subscribed to the same basic form or conception of happiness while differing over the details or content of happiness.

In this paper I want to discuss a well-known but poorly understood problem: how can socialists reconcile the observed paucity of cooperatives in capitalist societies with their alleged superiority on normative grounds? If cooperatives are so desirable, why don't workers desire them? If one's ideal of socialism is central planning, it is clear enough that it cannot emerge gradually within the womb of the capitalist economy. If instead it is something like market socialism, it is not clear that a discontinuous (...) transformation of society is required. If workers want socialism, they can start up here and now. If they don't, doesn't it prove that they do not want it? I shall proceed as follows. Section I argues that the usual explanation - that cooperatives are not economically viable or that workers prefer working in capitalist firms – is not necessarily correct. The explanation may lie elsewhere, in endogenous preference formation, adverse selection, discrimination, or externalities. Section II is concerned with the variety of cooperative arrangements. Only rarely do we find cooperatives in their pure form, with all workers and only workers having equal ownership rights. Non-working owners, non-owning workers and unequal distribution of shares are frequent. When the deviations become sufficiently large, the firms cease to become cooperatives in any meaningful sense. Section III extends the argument of Section I by surveying the causes of cooperative failure. Some fail by success: profitable cooperatives often attract or turn into private ownership. Others fail outright, partly because they tend to be established under unfavorable circumstances and partly because of intrinsic difficulties of management. (shrink)

In Pérez Laraudogoitia (1996), I introduced a simple example of a supertask that involved the possibility of spontaneous self-excitation and, therefore, of a particularly interesting form of indeterminism in classical dynamics. Alper and Bridger (1998) criticised (among other things) this result. In the present article, I answer their criticisms. In what follows I assume familiarity both with Pérez Laraudogoitia (1996) and Alper and Bridger’s subsequent article.

Multiple explanatory frameworks may be required to provide an adequate account of human cognition. This paper embeds the classical account within a neural network framework, exploring the encoding of syntacticallystructured objects over the synchronicdiachronic characteristics of networks. Synchronic structure is defined in terms of temporal binding and the superposition of states. To accommodate asymmetric relations, synchronic structure is subject to the type uniqueness constraint. The nature of synchronic structure is shown to underlie Xbar theory that characterizes the phrasal structure of (...) human languages. The derivation differentiates core Xbar properties from languagespecific properties. (shrink)
