Abstract: Do we apply higher epistemic standards to subjects with high stakes? This paper argues that we expect different outward behavior from high-stakes subjects – for example, we expect them to collect more evidence than their low-stakes counterparts – but not because of any change in epistemic standards. Rather, we naturally expect subjects in any condition to think in a roughly adaptive manner, balancing the expected costs of additional evidence collection against the expected value of gains in accuracy. The paper reviews a body of empirical work on the automatic regulation of cognitive effort in response to stakes, and argues that we naturally see high- and low-stakes subjects as experiencing different levels of ‘epistemic anxiety’, and anticipate different levels of cognitive effort from them for this reason. If unresolved epistemic anxiety always bars an ascription of knowledge, then we can explain our responses to cases involving shifting stakes without positing any variation in the standards of intuitive knowledge ascription.
Knowledge Ascription and the Psychological Consequences of Changing Stakes
Abstract: Why do our intuitive knowledge ascriptions shift when a subject’s practical interests are mentioned? Many efforts to answer this question have focused on empirical linguistic evidence for context sensitivity in knowledge claims, but the empirical psychology of belief formation and attribution also merits attention. The present paper examines a major psychological factor (called “need-for-closure”) relevant to ascriptions involving practical interests. Need-for-closure plays an important role in determining whether one has a settled belief; it also influences the accuracy of one’s cognition. Given these effects, it is a mistake to assume that high- and low-stakes subjects provided with the same initial evidence are perceived to enjoy belief formation that is the same as far as truth-conducive factors are concerned. This mistaken assumption has underpinned contextualist and interest-relative invariantist treatments of cases in which contrasting knowledge ascriptions are elicited by descriptions of subjects with the same initial information and different stakes. The paper argues that intellectualist invariantism in fact yields the best treatment of such cases.
Knowledge Ascription and the Psychological Consequences of Thinking about Errors
Abstract: Epistemologists generally agree that the stringency of intuitive ascriptions of knowledge is increased when unrealized possibilities of error are mentioned. Non-sceptical invanantists (Williamson, Hawthorne) think it a mistake to yield in such cases to the temptation to be more stringent, but they do not deny that we feel it. They contend that the temptation is best explained as the product of a psychological bias known as the availability heuristic. I argue against the availability explanation, and sketch a rival account of what happens to us psychologically when possibilities of error are raised.
The Ontology of Mind: Events, Processes, and States
Publisher’s Note: This book puts forward a radical critique of the foundations of contemporary philosophy of mind, arguing that it relies too heavily on insecure assumptions about the nature of some of the sorts of mental entities it postulates: the nature of events, processes, and states. The book offers an investigation of these three categories, clarifying the distinction between them, and argues specifically that the assumption that states can be treated as particular, event-like entities has been a huge and serious mistake. The book argues that the category of token state should be rejected, and develops an alternative way of understanding those varieties of causal explanation which have sometimes been thought to require an ontology of token states for their elucidation. The book contends that many current theories of mind are rendered unintelligible once it is seen how these explanations really work. A number of prominent features of contemporary philosophy of mind token identity theories, the functionalists conception of causal role, a common form of argument for eliminative materialism, and the structure of the debate about the efficacy of mental content are impugned by the book’s arguments. The book concludes that the modern mind-body problem needs to be substantially rethought.
On Sensations of Position
Summary: In this paper, Anscombe defends the view that there are various bodily positions, such as sitting cross-legged, that we “just know” about and don’t deduce from sensations or feelings any more than we might from visual clues. We use the term “sensation” in such cases as both an external description of what is the case, and as an internal description of what it feels like. The sensation is not broken down into other more primitive data, which we may not even be aware of, though if we were to attend to we might come to know.
Intention
Summary: Three core problems about intention are discussed: (i) expressions of intention; (ii) the intentional or non-intentional character of action; (iii) the intention of an action, or with which it is done. The book attempts to show in detail that the natural and widely accepted picture of what we mean by an intention gives rise to insoluble problems and must be abandoned.
Extended Rationality: A Hinge Epistemology
Publisher’s Note: Extended Rationality: A Hinge Epistemology provides a novel account of the structure of epistemic justification. Its central claim builds upon Wittgenstein’s idea in On Certainty that epistemic justifications hinge on some basic assumptions and that epistemic rationality extends to these very hinges. It exploits these ideas to address major problems in epistemology, such as the nature of perceptual justifications, external world skepticism, epistemic relativism, the epistemic status of basic logical laws, of the Principle of the Uniformity of Nature, of our belief in the existence of the past and of other minds, and the nature of testimonial justification. Along the way, further technical issues, such as the scope of the Principle of Closure of epistemic operators under known entailment, the notion of transmission failure, and the existence of entitlements are addressed in new and illuminating ways.
The Degree of Epistemic Justification and the Conjunction Fallacy
Abstract: This paper describes a formal measure of epistemic justification motivated by the dual goal of cognition, which is to increase true beliefs and reduce false beliefs. From this perspective the degree of epistemic justification should not be the conditional probability of the proposition given the evidence, as it is commonly thought. It should be determined instead by the combination of the conditional probability and the prior probability. This is also true of the degree of incremental confirmation, and I argue that any measure of epistemic justification is also a measure of incremental confirmation. However, the degree of epistemic justification must meet an additional condition, and all known measures of incremental confirmation fail to meet it. I describe this additional condition as well as a measure that meets it. The paper then applies the measure to the conjunction fallacy and proposes an explanation of the fallacy.
Against Gullibility
Summary: This paper refutes the PR thesis according to which the hearer has such a special presumptive right to trust the speaker’s assertion. The refutation consists of 1) arguing against that it is not possible for a hearer to obtain independent confirmation that a given speaker is trustworthy – that what she says will be true; 2) a full rejection to various positive arguments for a PR which may be made.
Indian Philosophy and Philosophy of Science
Summary: Sundar Sarukkai’s Indian Philosophy and Philosophy of Science shows how the two very different approaches from East and West can illuminate each other. It is not an introduction to the philosophy of science, but rather an invitation to look at philosophy of science in a new way, using the approaches of classical Indian logic, in particular Navya Nyāya . Sarukkai’s major thesis is that in the West philosophy of science tries to put logic into science, and that in the East Indian logic seeks to put science into logic. The naïve Western approach takes an abstract view of logic and formulates science using abstract logical and mathematical theories. Indian logic looks at the world and remains involved with the world throughout. Because of this, logical arguments have to involve contingent matters of fact or observation .Western readers may find the lack of distinction between induction and deduction disturbing, but the Eastern involvement with the world, not merely abstraction, reflects a different way of looking at what logic is and where its origins lie.
