Publisher’s Note: This major study of Hobbes’s political philosophy draws on recent developments in game and decision theory to explore whether the thrust of the argument in Leviathan, that it is in the interests of the people to create a ruler with absolute power, can be shown to be cogent. Professor Hampton has written a book of vital importance to political philosophers, political and social scientists, and intellectual historians.
Distorted Reflection
Abstract: Diachronic Dutch book arguments seem to support both conditionalization and Bas van Fraassen’s Reflection principle. But the Reflection principle is vulnerable to numerous counterexamples. This essay addresses two questions: first, under what circumstances should an agent obey Reflection, and second, should the counterexamples to Reflection make us doubt the Dutch book for conditionalization? In response to the first question, this essay formulates a new ‘Qualified Reflection’ principle, which states that an agent should obey Reflection only if he or she is certain that he or she will conditionalize on veridical evidence in the future. Qualified Reflection follows from the probability calculus together with a few idealizing assumptions. The essay then formulates a ‘Distorted Reflection’ principle that approximates Reflection even in cases where the agent is not quite certain that he or she will conditionalize on veridical evidence. In response to the second question, the essay argues that contrary to a common misconception, not all Dutch books dramatize incoherence – some dramatize a less blameworthy sort of epistemic frailty that the essay calls ‘self-doubt’. The distinction between Dutch books that dramatize incoherence and those that dramatize self-doubt cross-cuts the distinction between synchronic and diachronic Dutch books. The essay explains why the Dutch book for conditionalization reveals true incoherence, whereas the Dutch book for Reflection reveals only self-doubt.
Anti-individualism and knowledge
Publisher’s note: Contemporary philosophy of mind is dominated by anti-individualism, which holds that a subject’s thoughts are determined not only by what is inside her head but also by aspects of her environment. Despite its dominance, anti-individualism is subject to a daunting array of epistemological objections: that it is incompatible with the privileged access each subject has to her thoughts, that it undermines rationality, and, absurdly, that it provides a new route to a priori knowledge of the world. In this rigorous and persuasive study, Jessica Brown defends anti-individualism from these epistemological objections. The discussion has important consequences for key epistemological issues such as skepticism, closure, transmission, and the nature of knowledge and warrant.
According to Brown’s analysis, one main reason for thinking that anti-individualism is incompatible with privileged access is that it undermines a subject’s introspective ability to distinguish types of thoughts. So diagnosed, the standard focus on a subject’s reliability about her thoughts provides no adequate reply. Brown defuses the objection by appeal to the epistemological notion of a relevant alternative. Further, she argues that, given a proper understanding of rationality, anti-individualism is compatible with the notion that we are rational subjects. However, the discussion of rationality provides a new argument that anti-individualism is in tension with Fregean sense. Finally, Brown shows that anti-individualism does not create a new route to a priori knowledge of the world. While rejecting solutions that restrict the transmission of warrant, she argues that anti-individualists should deny that we have the type of knowledge that would be required to use a priori knowledge of thought content to gain a priori knowledge of the world.
The Epistemology of Resistance: Gender and Racial Oppression, Epistemic Injustice, and Resistant Imaginations
Abstract: This book explores the epistemic side of oppression, focusing on racial and sexual oppression and their interconnections. It elucidates how social insensitivities and imposed silences prevent members of different groups from interacting epistemically in fruitful ways-from listening to each other, learning from each other, and mutually enriching each other’s perspectives. Medina’s epistemology of resistance offers a contextualist theory of our complicity with epistemic injustices and a social connection model of shared responsibility for improving epistemic conditions of participation in social practices. Through the articulation of a new interactionism and polyphonic contextualism, the book develops a sustained argument about the role of the imagination in mediating social perceptions and interactions. It concludes that only through the cultivation of practices of resistance can we develop a social imagination that can help us become sensitive to the suffering of excluded and stigmatized subjects. Drawing on Feminist Standpoint Theory and Critical Race Theory, this book makes contributions to social epistemology and to recent discussions of testimonial and hermeneutical injustice, epistemic responsibility, counter-performativity, and solidarity in the fight against racism and sexism.
Modern Moral Philosophy
Abstract: I will begin by stating three theses which I present in this paper. The first is that it is not profitable for us at present to do moral philosophy; that should be laid aside at any rate until we have an adequate philosophy of psychology, in which we are conspicuously lacking. The second is that the concepts of obligation, and duty – moral obligation and moral duty, that is to say – and of what is morally right and wrong, and of the moral sense of “ought,” ought to be jettisoned if this is psychologically possible; because they are survivals, or derivatives from survivals, from an earlier conception of ethics which no longer generally survives, and are only harmful without it. My third thesis is that the differences between the wellknown English writers on moral philosophy from Sidgwick to the present day are of little importance.
Logical Quantifiers
Abstract: This article offers a logical, linguistic, and philosophical account of modern quantification theory. Contrasting the standard approach to quantifiers (according to which logical quantifiers are defined by enumeration) with the generalized approach (according to which quantifiers are defined systematically), the article begins with a brief history of standard quantifier theory and identifies some of its logical, linguistic, and philosophical strengths and weaknesses. It then proceeds to a brief history of generalized quantifier theory and explains how it overcomes the weaknesses of the standard theory. One of the main philosophical advantages of the generalized theory is its philosophically informative criterion of logicality. The paper describes the work done so far in this theory, highlights some of its central logical results, offers an overview of its main linguistic contributions, and discusses its philosophical significance.
What are Degrees of Belief?
Probabilism is committed to two theses:
1) Opinion comes in degrees – call them degrees of belief, or credences.
2) The degrees of belief of a rational agent obey the probability calculus.
Correspondingly, a natural way to argue for probabilism is:
i) to give an account of what degrees of belief are, and then
ii) to show that those things should be probabilities, on pain of irrationality.
Most of the action in the literature concerns stage ii). Assuming that stage i) has been adequately discharged, various authors move on to stage ii) with varied and ingenious arguments. But an unsatisfactory response at stage i) clearly undermines any gains that might be accrued at stage ii) as far as probabilism is concerned: if those things are not degrees of belief, then it is irrelevant to probabilism whether they should be probabilities or not.
In this paper, the authors scrutinize the state of play regarding stage i). We critically examine several of the leading accounts of degrees of belief: reducing them to corresponding betting behavior (de Finetti); measuring them by that behavior (Jeffrey); and analyzing them in terms of preferences and their role in decision-making more generally (Ramsey, Lewis, Maher). We argue that the accounts fail, and so they are unfit to subserve arguments for probabilism. We conclude more positively: “degree of belief” should be taken as a primitive concept that forms the basis of our best theory of rational belief and decision: probabilism.
Confirmation and reduction: A bayesian account
Abstract: Various scientific theories stand in a reductive relation to each other. In a recent article, the authors argue that a generalized version of the Nagel-Schaffner model (GNS) is the right account of this relation. In this article, they present a Bayesian analysis of how GNS impacts on confirmation. They formalize the relation between the reducing and the reduced theory before and after the reduction using Bayesian networks, and thereby show that, post-reduction, the two theories are confirmatory of each other. They ask when a purported reduction should be accepted on epistemic grounds. To do so, they compare the prior and posterior probabilities of the conjunction of both theories before and after the reduction and ask how well each is confirmed by the available evidence
Constructivism vs. Contractualism
Introduction: Are Constructivism and Contractualism different, and if so how? Seemingly they are not wholly different, and certainly not incompatible, since some writers have described themselves as both. As a first shot one might suggest that contractualists ground ethical or political justification in agreement of some sort, whereas constructivists ground them in some conception of reason. This will not provide any neat separation of the two approaches to justification, since agreement may provide a basis for reasons, and reasoning a way of achieving agreement. In opening up these questions a bit further I shall consider some of the moves John Rawls and Tim Scanlon make in talking about their own methods of ethics, and in particular, some of the connections they draw between their methods and the scope of their accounts of ethical reasoning.
Models and Modality
Abstract: This paper examines the connection between model-theoretic truth and necessary truth. It is argued that though the model-theoretic truths of some standard languages are demonstrably “necessary” (in a precise sense), the widespread view of model-theoretic truth as providing a general guarantee of necessity is mistaken. Several arguments to the contrary are criticized.
