This major work challenges some widely held positions in epistemology - those of Peirce and Popper on the one hand and those of Quine and Kuhn on the other.

This comprehensive discussion of the problem of rational belief develops the subject on the pattern of Bayesian decision theory. The analogy with decision theory introduces philosophical issues not usually encountered in logical studies and suggests some promising new approaches to old problems."We owe Professor Levi a debt of gratitude for producing a book of such excellence. His own approach to inductive inference is not only original and profound, it also clarifies and transforms the work of his predecessors. In short, (...) the book deserves to become a classic....There is a great deal of interest in the book besides these basic matters [forumlating rules of acceptance]. Some of the most interesting chapters are those that examine the implications of such rules. The discussions of probability, generalization, and various forms of inference are brilliant and enlightening. Indeed, the problems and methods elaborated by Professor Levi in his book serve as a new foundation for the study of inductive inference."--Keith Lehrer, Nous"Levi's book is an extremely interesting report on 'tentative and speculative first steps' toward a decision-theoretic approach to inductive inference....Professor Levi is to be congratulated on his ingenious development and application of this approach...."--Richard C. Jeffrey, The Journal of Philosophy. (shrink)

Isaac Levi's new book is concerned with how one can justify changing one's beliefs. The discussion is deeply informed by the belief-doubt model advocated by C. S. Peirce and John Dewey, of which the book provides a substantial analysis. Professor Levi then addresses the conceptual framework of potential changes available to an inquirer. A structural approach to propositional attitudes is proposed, which rejects the conventional view that a propositional attitude involves a relation between an agent and either a (...) linguistic entity or some other intentional object such as a proposition or set of possible worlds. The last two chapters offer an account of change in states of full belief understood as changes in commitments rather than changes in performance; one chapter deals with adding new information to a belief state, the other with giving up information. The book builds upon topics discussed in some of Levi's earlier work. It will be of particular interest to discussion theorists, epistemologists, philosophers of science, computer scientists, and cognitive psychologists. (shrink)

'At last one of the most famous generalizing works in anthropology by the field's most stimulating and controversial contemporary figure has been translated, beautifully, and with the enlightening preface of the second French edition.

It is a commonplace that in making decisions agents often have to juggle competing values, and that no choice will maximise satisfaction of them all. However, the prevailing account of these cases assumes that there is always a single ranking of the agent's values, and therefore no unresolvable conflict between them. Isaac Levi denies this assumption, arguing that agents often must choose without having balanced their different values and that to be rational, an act does not have to be (...) optimal, only what Levi terms 'admissible'. This book explores the consequences of denying the assumption and develops a general approach to decision-making under unresolved conflict. Professor Levi discusses conflicts of value in several domains - those arising in moral dilemmas, the drawing of scientific inferences, decisions taken under uncertainty, and in social choice. In each of these he adapts his theoretical framework, showing how conflict may often be reduced though not always altogether eliminated. (shrink)

Continental philosophy has entered a new period of ferment. The long deconstructionist era was followed with a period dominated by Deleuze, which has in turn evolved into a new situation still difficult to define. However, one common thread running through the new brand of continental positions is a renewed attention to materialist and realist options in philosophy. Among the leaders of the established generation, this new focus takes numerous forms. It might be hard to find many shared positions in the (...) writings of Badiou, DeLanda, Laruelle, Latour, Stengers, and Žižek, but what is missing from their positions is an obsession with the critique of written texts. All of them elaborate a positive ontology, despite the incompatibility of their results. Meanwhile, the new generation of continental thinkers is pushing these trends still further, as seen in currents ranging from transcendental materialism to the London-based speculative realism movement to new revivals of Derrida. As indicated by the title The Speculative Turn, the new currents of continental philosophy depart from the text-centered hermeneutic models of the past and engage in daring speculations about the nature of reality itself. This anthology assembles authors, of several generations and numerous nationalities, who will be at the centre of debate in continental philosophy for decades to come. (shrink)

For three centuries, philosophers have mounted defenses against the melan genie with an obsessive intensity comparable to the Reaganite determination to squander American wealth on defenses against a Communist threat. And for three centuries, skeptics have argued for the futility of the expenditure of conceptual effort with no more success than critics of the Pentagon have had in stemming the flow of funds to the military and its industrial minions. My own sympathies are with the skeptics. However, their own intense (...) involvement with the obsessions of the epistemological fear mongers and their failure to address the analogue of the problem of conversion from military to civilian industry in an acceptable manner often deprive the skeptical position of the subversive force it ought to have.

This book by one of the world's foremost philosophers in the fields of epistemology and logic offers an account of suppositional reasoning relevant to practical deliberation, explanation, prediction and hypothesis testing. Suppositions made 'for the sake of argument' sometimes conflict with our beliefs, and when they do, some beliefs are rejected and others retained. Thanks to such belief contravention, adding content to a supposition can undermine conclusions reached without it. Subversion can also arise because suppositional reasoning is ampliative. These two (...) types of nonmonotonic logic are the focus of this book. A detailed comparison of nonmonotonicity appropriate to both belief contravening and ampliative suppositional reasoning reveals important differences that have been overlooked. (shrink)

The external world sceptic tells some familiar narratives involving massive deception. Perhaps we are brains in vats. Perhaps we are the victim of a deceitful demon. You know the drill. The sceptic proceeds by observing first that victims of such deceptions know nothing about their external environment and that second, since we cannot rule out being a victim of such deceptions our- selves, our own external world beliefs fail to attain the status of knowledge. Discussions of global external world scepticism (...) tend to focus on the second step, where a number of well-known lines of resistance have been offered. But there has been little attention to the first, seemingly innocuous step. That will be the focus of this paper. Part one – sections 1, 2, and 3 – will explain why these standard narratives are not convincing examples of cases where there is no knowledge of the external world. In part two – section 4 – we shall undertake a useful case study. David Lewis’s ‘Elusive Knowledge’ is often thought of as presenting an epistemological vision that is somewhat friendly to external world scepticism: as Lewis himself presents things, there are contexts where external world knowledge ascriptions are uniformly false, and where true knowledge ascriptions are limited to either axiomatic truths or truths about our inner life. We examine his discussion in the light of the preceding reflections and show that the framework he presents is not so concessionary to global external world scepticism after all. (shrink)

This paper explores some consequences of Lewis’s (Australas J Philos 74(4):549–567, 1996) understanding of how knowledge is compartmentalized. It argues, first, that he underestimates how badly it impacts his view. When knowledge is compartmentalized, it lacks at least one of two essential features of Lewis’s account: (a) Elusiveness—familiar skeptical possibilities, when relevant, are incompatible with everyday knowledge. (b) Knowledge is a modality—when a thinker knows that p, there is no relevant possibility where p is false. Lewis proposes compartmentalized knowledge to (...) keep treating knowledge as a modality while mitigating one of its unrealistic epistemological implications: In normal modal epistemic logic (and standard possible world semantics), a thinker always counts as knowing the strongest proposition that follows from the set of all the individual propositions that this thinker knows. Lewis’s compartmentalization proposal is that thinkers merely know the conjunctions of propositions that are known in each of, but not across, their compartments. The irony is that in avoiding overblown knowledge the view now allows for thinkers to attend to skeptical error possibilities and yet knowledge is present. The account avoids inflation of knowledge in one sense only to acquire another type of knowledge the view denies subjects can have. This problem motivates an inspection of knowledge accounts whose intra-compartment closure principles are weaker than those that are valid in normal modal-logic. The conclusion is that some formulations of closure can avoid the challenge Lewis’s view faces. Nevertheless, even these closure principles pose a barrier—perhaps an implausible barrier—for knowledge of ignorance. Even when the reasoning supporting the lack of knowledge is sound, a subject cannot always know she doesn’t know. Interestingly, this obstacle is one that knowledge of knowledge doesn’t seem to face.

Bayesians often confuse insistence that probability judgment ought to be indeterminate (which is incompatible with Bayesian ideals) with recognition of the presence of imprecision in the determination or measurement of personal probabilities (which is compatible with these ideals). The confusion is discussed and illustrated by remarks in a recent essay by R. C. Jeffrey.

The article responds to some of the points raised by B. van Fraassen concerning probability kinematics and direct inference within the framework of the approach to the revision of probability judgment proposed by Levi in The Enterprise of Knowledge. In particular, the critical importance of the question of direct inference is emphasized and explained.

By reappraising the biological theory of vitalism, Canguilhem attempted to give pride of place to the idea that acquiring knowledge about living beings is an activity of living beings. He is indeed credited with the view that knowledge in particular and rationality in general are “tied to a conception of life” whereby “life predominantly manifests itself in organic individuals that act and react within specific environments which, in turn, are defined by the needs and desires of these individuals” (Schmidgen H. (...) Hist Philos Life Sci, 36(2): 4, 2014. doi:10.1007/s40656-014-0030-1). These needs and desires, we are told, constitute “un système de référence irréductible et par là absolu” (Canguilhem G. Le vivant et son milieu. In: La connaissance de la vie (Deuxième édition revue et augmenté). Librairie philosophique J. Vrin, 129–154, 1992c). Canguilhem’s legacy is exactly this: rationality is rooted in life, and not the other way around. And yet, in “Le concept et la vie” (from 1966) and “De la science et de la contre-science” (from 1971), Canguilhem seems to tell another story about the complex intertwinement of life and rationality. Not only are we condemned to enter the realm of rationality (i.e., to take part in logical activities such as forming concepts and judgments about the world and about our own condition) because we have needs and desires as living beings, but we also have needs and desires as living beings that depend on the fact we are always already caught-up in the dynamics of rationality, i.e., always already logically active. At this point, Canguilhem’s thinking comes closer than ever to a Kantian, transcendental point of view on rationality. Paradoxically, the inscription of human rationality in organic life brings with it the idea of a subject, divided between two inverse but correlated realms in which it cannot but participate: the singular realm of sensibility and the general realm of logic.

Several authors have recently contended that modern statistical theory provides a powerful argument in favor of the view that if scientists accept or reject hypotheses at all they do so only in a behavioral sense--i.e., in a sense which reduces "accepting P" to "acting on the basis of P relative to an objective O". In this paper, the argument from statistics in favor of a behavioral view is outlined; an interpretation of two statistical procedures (Bayes method and signifigance testing) is (...) offered which does not entail a behavioral analysis of "accepting a hypothesis"; and the conclusion that non-behavioral analyses of belief are compatible with the application of current statistical theory in the sciences is tentatively advanced.

In the context of change to the “new modernity” described in Beck’s work, companies develop management modes and methods that focus more and more on individuals. Constitutive of the individualization process, human resources practices have become ambivalent as the process itself. This contribution examines how a managerial and organizational innovation as telework contributes to the process of individualization, and the paradoxes it addresses to management. At the interface of the social and the technical, teleworking appears as a flexible arrangement, meeting (...) employees’ and employer’s demands – which is a characteristic of the process of individualization – by simultaneously fragmenting collectivity, exposing individuals to social risk, and producing exclusion. The authors focus on two consecutive paradoxes of such individualized managerial practices: the individual–collective dilemma and the autonomy–control paradox. Finally, the paper reveals HRM as a new institution of individualization in a world where regulation functions are more and more transferred to individuals themselves. (shrink)

Frank Ebersole's extraordinary investigations of certain key philosophical ideas behind problems in epistemology and metaphysics are the subject of this article-review. I have resisted providing what many readers will expect me to provide, namely, a critical examination of his philosophical methodology. I do question his unwilligness to say why his investigations only yield I negative results, and I do have something to say about classifying him as an ordinary language philosopher. However, my main focus is on trying to engage critically (...) with what he actually does in his work. To this end, I provide a narrative of the investigation he carries out into the possibility of comparing the objects of perception and dreams, and I cite other works of his in support of my understanding of that investigation. Although one of his lengthiest essays seems to be devoted to an anticipation of an objection to his approach, I explain why even there he is not concerned with the question of why he always seems to get negative results. After suggesting why some of his later essays seem to be so hard to read, I conclude by saying something about what I take to be his achievement. (shrink)

I respond to Erik Olsson's critique of my account of contraction frominconsistent belief states, by admitting that such contraction cannot be rationalized as adeliberate decision problem. It can, however, be rationalized as a routine designed prior toinadvertent expansion into inconsistency when the deliberating agent embraces a consistent point of view.

In the face of mounting criticism against advance directives, we describe how a novel, computer-based decision aid addresses some of these important concerns. This decision aid, Making Your Wishes Known: Planning Your Medical Future , translates an individual's values and goals into a meaningful advance directive that explicitly reflects their healthcare wishes and outlines a plan for how they wish to be treated. It does this by (1) educating users about advance care planning; (2) helping individuals identify, clarify, and prioritize (...) factors that influence their decision-making about future medical conditions; (3) explaining common end-of-life medical conditions and life-sustaining treatment; (4) helping users articulate a coherent set of wishes with regard to advance care planning—in the form of an advance directive readily interpretable by physicians; and (5) helping individuals both choose a spokesperson, and prepare to engage family, friends, and health care providers in discussions about advance care planning.
