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 lottery paradox, knowledge and rationality
Summary: The knowledge version of the paradox arises because it appears that we know our lottery ticket (which is not relevantly different from any other) will lose, but we know that one of the tickets sold will win. The rationality version of the paradox arises because it appears that it is rational to believe of each single ticket in, say, a million-ticket lottery that it will not win, and that it is simultaneously rational to believe that one such ticket will win. It seems, then, that we are committed to attributing two rational beliefs to a single agent at a single time, beliefs that, together with a few background assumptions, are inconsistent and can be seen by the agent to be so. This has seemed to many to be a paradoxical result: an agent in possession of two rational beliefs that she sees to be inconsistent. In my paper, I offer a novel solution to the paradox in both its rationality and knowledge versions that emphasizes a special feature of the lottery case, namely, the statistical nature of the evidence available to the agent. On my view, it is neither true that one knows nor that it is rational to believe that a particular ticket will lose. While this might seem surprising at first, it has a natural explanation and lacks the serious disadvantages of competing solutions.
How many kinds of reasons?
Abstract: Reasons can play a variety of roles in a variety of contexts. For instance, reasons can motivate and guide us in our actions (and omissions), in the sense that we often act in the light of reasons. And reasons can be grounds for beliefs, desires and emotions and can be used to evaluate, and sometimes to justify, all these. In addition, reasons are used in explanations: both in explanations of human actions, beliefs, desires, emotions, etc., and in explanations of a wide range of phenomena involving all sorts of animate and inanimate substances. This diversity has encouraged the thought that the term ‘reason’ is ambiguous or has different senses in different contexts. Moreover, this view often goes hand in hand with the claim that reasons of these different kinds belong to different ontological categories: to facts (or something similar) in the case of normative/justifying reasons, and to mental states in the case of motivating/explanatory reasons. In this paper I shall explore some of the main roles that reasons play and, on that basis, I shall offer a classification of kinds of reasons. As will become clear, my classification of reasons is at odds with much of the literature in several respects: first, because of my views about how we should understand the claim that reasons are classified into different kinds; second, because of the kinds into which I think reasons should be classified; and, finally, because of the consequences I think this view has for the ontology of reasons.
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.
The Justification of Deduction
Abstract: It is often taken for granted by writers who propose – and, for that matter, by writers who oppose – ‘justifications’ of inductions, that deduction either does not need, or can readily be provided with, justification. The purpose of this paper is to argue that, contrary to this common opinion, problems analogous to those which, notoriously, arise in the attempt to justify induction, also arise in the attempt to justify deduction.
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.
Critical notice: Telling and trusting: Reductionism and anti-reductionism in the epistemology of testimony
Abstract: In this review I focus on the arguments advanced by Coady in the main task to which he addresses himself in Testimony: arguing the case against the reductive position, and in favour of a non-reductive conception of testimonial knowledge. I introduce some distinctions which I believe enable the subject to taken further.
Epistemic Intuitions
Abstract: We naturally evaluate the beliefs of others, sometimes by deliberate calculation, and sometimes in a more immediate fashion. Epistemic intuitions are immediate assessments arising when someone’s condition appears to fall on one side or the other of some significant divide in epistemology. After giving a rough sketch of several major features of epistemic intuitions, this article reviews the history of the current philosophical debate about them and describes the major positions in that debate. Linguists and psychologists also study epistemic assessments; the last section of the paper discusses some of their research and its potential relevance to epistemology.
Against Physicalism-plus-God
Abstract: It is often assumed that contemporary physics is more hospitable to divine action (and human freedom) than classical mechanics. The article criticizes this assumption on the grounds of both physics and theology. Most currently discussed models of divine action do not challenge the physicalist assumption that physics provides a true and complete description of nature’s causal web. Thus they resemble physicalism-plus-God. Taking up suggestions from Herman Dooyeweerd and Henri Blocher, I propose an alternative framework for divine action in the world. It takes creation as the starting-point to understand the world and leads to a non-reductionist, multidimensional picture of reality
