Edmund Gettier is Professor Emeritus at the University of Massachusetts, Amherst. This short piece, published in 1963, seemed to many decisively to refute an otherwise attractive analysis of knowledge. It stimulated a renewed effort, still ongoing, to clarify exactly what knowledge comprises.

I argue against the orthodox view of the relationship between propositional and doxastic justification. The view under criticism is: if p is propositionally justified for S in virtue of S's having reason R, and S believes p on the basis of R, then S's belief that p is doxastically justified. I then propose and evaluate alternative accounts of the relationship between propositional and doxastic justification, and conclude that we should explain propositional justification in terms of doxastic justification. If correct, this (...) proposal would constitute a significant advance in our understanding of the sources of epistemic justification. (shrink)

A theory of evidential probability is developed from two assumptions:(1) the evidential probability of a proposition is its probability conditional on the total evidence;(2) one's total evidence is one's total knowledge. Evidential probability is distinguished from both subjective and objective probability. Loss as well as gain of evidence is permitted. Evidential probability is embedded within epistemic logic by means of possible worlds semantics for modal logic; this allows a natural theory of higher-order probability to be developed. In particular, it is (...) emphasized that it is sometimes uncertain which propositions are part of one's total evidence; some surprising implications of this fact are drawn out. (shrink)

Intuitively, Gettier cases are instances of justified true beliefs that are not cases of knowledge. Should we therefore conclude that knowledge is not justified true belief? Only if we have reason to trust intuition here. But intuitions are unreliable in a wide range of cases. And it can be argued that the Gettier intuitions have a greater resemblance to unreliable intuitions than to reliable intuitions. Whats distinctive about the faulty intuitions, I argue, is that respecting them would mean abandoning a (...) simple, systematic and largely successful theory in favour of a complicated, disjunctive and idiosyncratic theory. So maybe respecting the Gettier intuitions was the wrong reaction, we should instead have been explaining why we are all so easily misled by these kinds of cases. (shrink)

My concern in this paper will be to explore and develop a version of nonsocratic skepticism about weakness of will. In my view, socratism is incorrect, but like Socrates, I think that the common understanding of weakness of will raises serious problems. Contrary to socratism, it is possible for a person knowingly to act contrary to his or her better judgment. But this description does not exhaust the common view of weakness. Also implicit in this view is the belief that (...) actions which are contrary to one's better judgment are free in the sense that the agent could have done otherwise. To take seriously the possibility of acting contrary to one's better judgment is at the same time to raise problems about the distinction between weakness and compulsion. I argue that the common view, according to which the differentiating feature is that the weak are able to conform their behavior to their practical judgments, is unjustified. Instead, I have proposed that weakness of will involves the failure to develop certain normal capacities of self-control, whereas compulsion involves desires which even the possession of such capacities would not enable one to resist.

Jason Stanley presents a startling and provocative claim about knowledge: that whether or not someone knows a proposition at a given time is in part determined by his or her practical interests, i.e. by how much is at stake for that person at that time. In defending this thesis, Stanley introduces readers to a number of strategies for resolving philosophical paradox, making the book essential not just for specialists in epistemology but for all philosophers interested in philosophical methodology. Since a (...) number of his strategies appeal to linguistic evidence, it will be of great interest to linguists as well. (shrink)

Jason Stanley's "Knowledge and Practical Interests" is a brilliant book, combining insights about knowledge with a careful examination of how recent views in epistemology fit with the best of recent linguistic semantics. Although I am largely convinced by Stanley's objections to epistemic contextualism, I will try in what follows to formulate a version that might have some prospect of escaping his powerful critique.

Is it harder to acquire knowledge about things that really matter to us than it is to acquire knowledge about things we don't much care about? Jason Stanley 2005 argues that whether or not the relational predicate 'knows that' holds between an agent and a proposition can depend on the practical interests of the agent: the more it matters to a person whether p is the case, the more justification is required before she counts as knowing that p. The evidence (...) for Stanley's thesis includes a number of intuitive judgments about examples. In this paper we provide parallel examples for which Stanley's thesis requires unwelcome knowledge-attributions, and argue that this is possible because his thesis conflicts with familiar and plausible principles about knowledge.

It seems to be a truism that whenever we do something - and so, given the omnipresence of trying (Hornsby 1980), whenever we try to do something - we want to do that thing more than we want to do anything else we can do (Davidson 1970). However, according to Frog, when we have will power we are able to try not to do something that we ‘really want to do’. In context the idea is clearly meant to be that (...) what we really want to do and what we most want to do are one and the same. But how is this meant to be so much as possible? It seems to require that our desire not to do what we most want to do is both our strongest desire and not our strongest desire. And that is a blatant contradiction. This is the so-called ‘paradox of self-control’ (Mele 1987). The aim of our paper is to explain how to make sense of the story of Frog and Toad. (shrink)

Knowledge and Lotteries is organized around an epistemological puzzle: in many cases, we seem consistently inclined to deny that we know a certain class of propositions, while crediting ourselves with knowledge of propositions that imply them. In its starkest form, the puzzle is this: we do not think we know that a given lottery ticket will be a loser, yet we normally count ourselves as knowing all sorts of ordinary things that entail that its holder will not suddenly acquire a (...) large fortune. After providing a number of specific and general characterizations of the puzzle, Hawthorne carefully examines the competing merits of candidate solutions. In so doing, he explores a number of central questions concerning the nature and importance of knowledge, including the relationship of knowledge to assertion and practical reasoning, the status of epistemic closure principles, the merits of various brands of scepticism, the prospects for a contextualist account of knowledge, and the potential for other sorts of salience-sensitive accounts. Along the way, he offers a careful treatment of pertinent issues at the foundations of semantics. His book will be of interest to anyone working in the field of epistemology, as well as to philosophers of language. (shrink)

Thoughts and other mental states are defined by their role in a functional system. Since it is easier to determine when we have knowledge than when reasoning has occurred, Gilbert Harman attempts to answer the latter question by seeing what assumptions about reasoning would best account for when we have knowledge and when not. He describes induction as inference to the best explanation, or more precisely as a modification of beliefs that seeks to minimize change and maximize explanatory coherence.

Behaviour norms are considered for decision trees which allow both objective probabilities and uncertain states of the world with unknown probabilities. Terminal nodes have consequences in a given domain. Behaviour is required to be consistent in subtrees. Consequentialist behaviour, by definition, reveals a consequence choice function independent of the structure of the decision tree. It implies that behaviour reveals a revealed preference ordering satisfying both the independence axiom and a novel form of sure-thing principle. Continuous consequentialist behaviour must be expected (...) utility maximizing. Other plausible assumptions then imply additive utilities, subjective probabilities, and Bayes' rule. (shrink)

It has become recently popular to suggest that knowledge is the epistemic norm of practical reasoning and that this provides an important constraint on the correct account of knowledge, one which favours subject-sensitive invariantism over contextualism and classic invariantism. I argue that there are putative counterexamples to both directions of the knowledge norm. Even if the knowledge norm can be defended against these counterexamples, I argue that it is a delicate issue whether it is true, one which relies on fine (...) distinctions among a variety of relevant notions of propriety which our intuitions may reflect. These notions variously apply to the agent herself, her character traits, her beliefs, her reasoning and any resultant action. Given the delicacy of these issues, I argue that the knowledge norm is not a fixed point from which to defend substantive and controversial views in epistemology. Rather, these views need to be defended on other grounds. (shrink)

For Permissions, please email: [email protected] Blome-Tillmann’s Knowledge and Presuppositions proposes and defends a novel form of epistemological contextualism. As the title would suggest, the view’s novelty lies in its deployment of the pragmatic-theoretic concept of a conversational presupposition to delineate a role for context in shaping the meaning of our knowledge claims. Over the course of six dense, argument-filled chapters, Blome-Tillmann brings his (...) approach into focus and claims for it several advantages. While existing varieties of contextualism can account for widely shared intuitions about the truth values of knowledge ascriptions in various familiar thought experiments, the distinctive flexibility of Presuppositional Epistemological Contextualism, Blome-Tillmann argues, enables it to account as well for cases in which our intuitions diverge. This flexibility also allows for especially satisfying analyses of scepticism... (shrink)

This book is a major contribution to decision theory, focusing on the question of when it is rational to accept scientific theories. The author examines both Bayesian decision theory and confirmation theory, refining and elaborating the views of Ramsey and Savage. He argues that the most solid foundation for confirmation theory is to be found in decision theory, and he provides a decision-theoretic derivation of principles for how many probabilities should be revised over time. Professor Maher defines a notion of (...) accepting a hypothesis, and then shows that it is not reducible to probability and that it is needed to deal with some important questions in the philosophy of science. A Bayesian decision-theoretic account of rational acceptance is provided together with a proof of the foundations for this theory. A final chapter shows how this account can be used to cast light on such vexed issues as verisimilitude and scientific realism. (shrink)
