First published in 1982, Ellery Eells' original work on rational decision making had extensive implications for probability theorists, economists, statisticians and psychologists concerned with decision making and the employment of Bayesian principles. His analysis of the philosophical and psychological significance of Bayesian decision theories, causal decision theories and Newcomb's paradox continues to be influential in philosophy of science. His book is now revived for a new generation of readers and presented in a fresh twenty-first-century series livery, including a specially (...) commissioned preface written by Brian Skyrms, illuminating its continuing importance and relevance to philosophical enquiry.

In past years, the traditional Bayesian theory of rational decision making, based on subjective calculations of expected utility, has faced powerful attack from philosophers such as David Lewis and Brian Skyrms, who advance an alternative causal decision theory. The test they present for the Bayesian is exemplified in the decision problem known as 'Newcomb's paradox' and in related decision problems and is held to support the prescriptions of the causal theory. As well as his conclusions, the concepts and methods of (...) Professor Eells introduces in the course of his analyses have extensive implications, not solely for probability theorists narrowly conceived, but for economists, statisticians and psychologists concerned with decision making and the employment of Bayesian principles. They and their students will, in addition, find the early chapters of great use as a background and introduction to the subject as a whole. (shrink)

In this important book, Ellery Eells explores and refines philosophical conceptions of probabilistic causality. In a probabilistic theory of causation, causes increase the probability of their effects rather than necessitate their effects in the ways traditional deterministic theories have specified. Philosophical interest in this subject arises from attempts to understand population sciences as well as indeterminism in physics. Taking into account issues involving spurious correlation, probabilistic causal interaction, disjunctive causal factors, and temporal ideas, Professor Eells advances the analysis of (...) what it is for one factor to be a positive causal factor for another. A salient feature of the book is a theory of token level probabilistic causation in which the evolution of the probability of a later event from an earlier event is central. This will be a book of crucial significance to philosophers of science and metaphysicians; it will also prove stimulating to many economists, psychologists, and physicists. (shrink)

To clarify and illuminate the place of probability in science Ellery Eells and James H. Fetzer have brought together some of the most distinguished philosophers ...

After clarifying the probabilistic conception of causality suggested by Good (1961-2), Suppes (1970), Cartwright (1979), and Skyrms (1980), we prove a sufficient condition for transitivity of causal chains. The bearing of these considerations on the units of selection problem in evolutionary theory and on the Newcomb paradox in decision theory is then discussed.

Several forms of symmetry in degrees of evidential support areconsidered. Some of these symmetries are shown not to hold in general. This has implications for the adequacy of many measures of degree ofevidential support that have been proposed and defended in the philosophical literature.

Science aims at the discovery of general principles of special kinds that are applicable for the explanation and prediction of the phenomena of the world in the form of theories and laws. When the phenomena themselves happen to be general, the principlesinvolved assume the form of theories; and when they are p- ticular, they assume the form of general laws. Theories themselves are sets of laws and de nitions that apply to a common domain, which makes laws indispensable to science. (...) Understanding science thus depends upon understanding the nature of theories and laws, the logical structure of explanations and predictions based upon them, and the principles of inference and decision that apply to theories and laws. Laws and theories can differ in their form as well as in their content. The laws of quantum mechanics are indeterministic, for example, while those of classical mechanics are deterministic instead. The history of science re ects an increasing role for probabilities as properties of the world but also as measures of evidential support and as degrees of subjective belief. Our purpose is to clarify and illuminate the place of probability in science. (shrink)

Sally Sedgwick presents a fresh account of Hegel's critique of Kant's theoretical philosophy. She argues that Hegel offers a compelling critique of and alternative to the conception of cognition that Kant defended in his 'Critical' period, and explores Hegel's claim to derive from Kantian doctrines clues to a superior form of idealism.

This study of the "radicalization" of psychiatry analyzes the writings of Laing, Foucault, Szasz, and Goffman, constructs a model for understanding mental illness, and emphasizes collective responsibility for the care of the mentally ill.

After a brief presentation of evidential decision theory, causal decision theory, and Newcomb type prima facie counterexamples to the evidential theory, three kinds of "metatickle" defenses of the evidential theory are discussed. Each has its weaknesses, but one of them seems stronger than the other two. The weaknesses of the best of the three, and the intricacy of metatickle analysis, does not constitute an advantage of causal decision theory over the evidential theory, however. It is argued, by way of an (...) example, that causal decision theory also stands in need of a metatickle defense. (shrink)

It is possible for a causal factor to raise the probability of a second factor in some situations while lowering the probability of the second factor in other situations. Must a genuine cause always raise the probability of a genuine effect of it? When it does not always do so, an "interaction" with some third factor may be the reason. I discuss causal interaction from the perspectives of Giere's counterfactual characterization of probabilistic causal connection (1979, 1980) and the "contextual unanimity" (...) model developed by, among others, Cartwright (1979) and Skyrms (1980). I argue that the contextual unanimity theory must exercise care, in a new way that seems to have gone unnoticed, in order to adequately accommodate the phenomenon, and that the counterfactual theory must be substantially revised; although it will still, pending clarification of a second kind of revision, be unable to accommodate a kind of interaction exemplified in cases like those described by Sober (1982).

This collection of essays is on the relation between probabilities, especially conditional probabilities, and conditionals. It provides negative results which sharply limit the ways conditionals can be related to conditional probabilities. There are also positive ideas and results which will open up areas of research. The collection is intended to honour Ernest W. Adams, whose seminal work is largely responsible for creating this area of inquiry. As well as describing, evaluating, and applying Adams's work the contributions extend his ideas in (...) directions he may or may not have anticipated, but that he certainly inspired. In addition to a wide range of philosophers of science, the volume should interest computer scientists and linguists. (shrink)

Immanuel Kant's Groundwork of the Metaphysics of Morals of 1785 is one of the most profound and important works in the history of practical philosophy. In this introduction to the Groundwork, Sally Sedgwick provides a guide to Kant's text that follows the course of his discussion virtually paragraph by paragraph. Her aim is to convey Kant's ideas and arguments as clearly and simply as possible, without getting lost in scholarly controversies. Her introductory chapter offers a useful overview of Kant's (...) general approach to practical philosophy, and she also explores and clarifies some of the main assumptions which Kant relies on in his Groundwork but defends in his Critique of Pure Reason. The book will be a valuable guide for all who are interested in Kant's practical philosophy. (shrink)

In a time when controlling the spread of the virus in the United States requires drastic measures to limit the number of people coming in and out of intensive care units, the presence of prison guards in not justified. Transfers from American prisons to hospitals have increased dramatically during the pandemic and with each prison patient comes a cohort of prison guards. The theoretical benefits of having prison guards–such as preventing escape, protecting staff, and stopping unwanted visitation–are minimal: critically ill (...) prisoners are chained to their bed and pose minimal threat to the staff or flight risk. Unwanted visitation is already heavily regulated by the hospital. The risks of having more people in the ICU are significant during the pandemic: more potential exposures for staff, other patients, and the guards themselves. In order to limit the spread of the virus, the number of prison guards in the ICU should be limited. (shrink)

This article considers the nature of global governance, and the response of the churches to global governance, looking especially at international relations and the economy, and issues of social justice and equity.

This critical survey of issues in European philosophy offers detailed accounts of crucial texts by important thinkers. Sedgwick draws key ideas from these sources, analyzing the various relationships between them and linking them to central themes in philosophical enquiry, such as the nature of subjectivity, reason and experience, anti-humanism, and the nature of language.Areas explored include epistemology, metaphysics and ontology, ethics and politics. Aspects of the work of a broad range of thinkers is considered in detail, including Descartes, Locke, (...) Hume, Kant, Hegel, Nietzsche, Adorno and Horkheimer, Heidegger, Deleuze and Guatarri, Levinas, Derrida, Althusser, Foucault and Lyotard. This intriguing new work presents the complex ideas of European philosophy in a straightforward manner, and will be of interest to both introductory and advanced-level readers. (shrink)

Bayesian epistemology suggests various ways of measuring the support that a piece of evidence provides a hypothesis. Such measures are defined in terms of a subjective probability assignment, pr, over propositions entertained by an agent. The most standard measure (where “H” stands for “hypothesis” and “E” stands for “evidence”) is: the difference measure: d(H,E) = pr(H/E) - pr(H).0 This may be called a “positive (probabilistic) relevance measure” of confirmation, since, according to it, a piece of evidence E qualitatively confirms a (...) hypothesis H if and only if pr(H/E) > pr(H), where qualitative disconfirmation is characterized by replacing “>” with “ “ with “=”. Other more or less standard positive relevance measures that have been proposed are: the log-ratio measure: r(H,E) = log[pr(H/E)/pr(H)] and the log-likelihood-ratio measure: l(H,E) = log[pr(E/H)/pr(E/~H)].

In Nietzsche's Justice, Peter Sedgwick takes the theme of justice to the very heart of the great thinker's philosophy. He argues that Nietzsche's treatment of justice springs from an engagement with the themes charted in his first book, The Birth of Tragedy, which invokes the notion of an absolute justice grasped by way of artistic metaphysics. Nietzsche's encounter with Greek tragedy spurs the development of an oracular conception of justice capable of transcending rigid social convention. Sedgwick argues that (...) although Nietzsche's later writings reject his earlier metaphysics, his mature thought is not characterized by a rejection of the possibility of the oracular articulation of justice found in the Birth. Rather, in the aftermath of his rejection of traditional accounts of the nature of will, moral responsibility, and punishment, Nietzsche seeks to rejuvenate justice in naturalistic terms. This rejuvenation is grounded in a radical reinterpretation of the nature of human freedom and in a vision of genuine philosophical thought as the legislation of values and the embracing of an ethic of mercy. The pursuit of this ethic invites a revaluation of the principles explored in Nietzsche's last writings. Smart, concise, and accessibly written, Nietzsche's Justice reveals a philosopher who is both socially embedded and oriented toward contemporary debates on the nature of the modern state. (shrink)

The Origins of Anglican Moral Theology shows how Anglican moral theology draws on Abelard, Aquinas, Scotus, Luther and Calvin. Perkins, Hooker, Sanderson and Taylor express its flowering from 1590 to 1670.

One of us (Eells 1982) has defended traditional evidential decision theory against prima facie Newcomb counterexamples by assuming that a common cause forms a conjunctive fork with its joint effects. In this paper, the evidential theory is defended without this assumption. The suggested rationale shows that the theory's assumptions are not about the nature of causality, but about the nature of rational deliberation. These presuppositions are weak enough for the argument to count as a strong justification of the evidential theory.

John Dupré (1984) has recently criticized the theory of probabilistic causality developed by, among others, Good (1961-62), Suppes (1970), Cartwright (1979), and Skyrms (1980). He argues that there is a tension or incompatibility between one of its central requirements for the presence of a causal connection, on the one hand, and a feature of the theory pointed out by Elliott Sober and me (1983), on the other. He also argues that the requirement just alluded to should be given up. I (...) defend the theory against Dupré's criticisms and conclude with comments on Dupré's appraisal of the bearing of his arguments on the nature of probabilistic causal laws. (shrink)

I argue that to the extent to which philosophical theories of objective probability have offered theoretically adequate conceptions of objective probability , they have failed to satisfy a methodological standard -- roughly, a requirement to the effect that the conception offered be specified with the precision appropriate for a physical interpretation of an abstract formal calculus and be fully explicated in terms of concepts, objects or phenomena understood independently of the idea of physical probability. The significance of this, and of (...) the suggested methodological standard, is then briefly discussed. (shrink)

The paper argues for a normative rather than psychological interpretation of Nietzsche's conceptions of power and will - and hence will to power. It does so with a view to rethinking the questions of Nietzsche's relationship to Enlightenment thought. Jürgen Habermas's view of Nietzsche's philosophy of power as epitomizing a counter-Enlightenment instrumentalism is contrasted with Maudmarie Clark's attempt to divest it of its power aspect in order to place him within the tradition of Enlightenment. Both approaches, it is argued, ignore (...) the irreducibly normative basis of Nietzsche's conception of will to power. This normative basis suggests that Nietzsche's thought can in fact contribute to the reconfiguration of our concept of rationality recently urged by Habermas.In der Abhandlung wird in Abgrenzung zur psychologischen ein normative Interpretation von Nietzsches Auffassung von Macht und Willen, und folglich seiner Idee vom Willen zur Macht, vorgestellt, mit der zugleich Nietzsches Beziehung zum Denken der Aufklärung revidiert werden soll. Dazu wird zunächst Jürgen Habermas' verkürzte Deutung von Nietzsches Philosophie der Macht als eines Instruments der Gegenaufklärung mit Maudmarie Clarks Versuch konfrontiert, Nietzsches Philosophie ihres Machtaspektes zu berauben und ihn so in die Tradition der Aufklärung zu stellen. Es wird gezeigt, das beide Interpretationsversuch die nicht reduzierbar normative Basis von Nietzsches Begriff des Willens zur Macht ignorieren. Dagegen legt die normative Deutung nahe, dass Nietzsches Denken tatsächlich zur Rekonfiguration unseres Vernunftkonzeptes beitragen kann, wie sie jüngst von Habermas gefordet wurde. (shrink)
