Judging by our folk appraisals, then, knowledge and action are intimately related. The theories of rational action with which we are familiar leave this unexplained. Moreover, discussions of knowledge are frequently silent about this connection. This is a shame, since if there is such a connection it would seem to constitute one of the most fundamental roles for knowledge. Our purpose in this paper is to rectify this lacuna, by exploring ways in which knowing something is related to rationally acting (...) upon it, defending one particular proposal against anticipated objections.

Recent work by Joshua Knobe indicates that people’s intuition about whether an action was intentional depends on whether the outcome is good or bad. This paper argues that part of the explanation for this effect is that there are stable individual differences in how ‘intentional’ is interpreted. That is, in Knobe’s cases, different people interpret the term in different ways. This interpretive diversity of ‘intentional’ opens up a new avenue to help explain Knobe’s results. Furthermore, the paper argues that the (...) use of intuitions in philosophy is complicated by fact that there are robust individual differences in intuitions about matters of philosophical concern.

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

Evidentialism is the thesis that epistemic justification for belief supervenes on evidential support. However, we claim there are cases in which, even though two subjects have the same evidential support for a proposition, only one of them is justified. What make the difference are pragmatic factors, factors having to do with our cares and concerns. Our argument against evidentialism is not based on intuitions about particular cases. Rather, we aim to provide a theoretical basis for rejecting evidentialism by defending a (...) “pragmatic” necessary condition on epistemic justification. We argue for the following necessary condition for justification: S is justified in believing that p only if S is rational to prefer (and, hence, act) as if p. In light of this necessary condition, the price of evidentialism is skepticism, or something close to it. (shrink)

In a recent paper, Al Mele (2003) suggests that the Simple View of intentional action is “fiction” because it is “wholly unconstrained” by a widely shared (folk) concept of intentional action. The Simple View (Adams, 1986, McCann, 1986) states that an action is intentional only if intended. As evidence that the Simple View is not in accord with the folk notion of intentional action, Mele appeals to recent surveys of folk judgments by Joshua Knobe (2003, 2004a, 2004b). Knobe’s surveys appear (...) to show that the folk judge unintended but known side effects of actions to be performed intentionally. In this paper we will reject Mele’s suggestion that the Simple View is “fiction.” We will also discuss the relationship between surveys and philosophical theories, and the abilities of surveys to access folk core concepts. We will argue that considerations of both fail to support Mele’s suggestion. (shrink)

Four experiments examined people’s folk-psychological concept of intentional action. The chief question was whether or not _evaluative _considerations — considerations of good and bad, right and wrong, praise and blame — played any role in that concept. The results indicated that the moral qualities of a behavior strongly influence people’s judgements as to whether or not that behavior should be considered ‘intentional.’ After eliminating a number of alternative explanations, the author concludes that this effect is best explained by the hypothesis (...) that evaluative considerations do play some role in people’s concept of intentional action.<b> </b>.

Recent studies point to a surprising divergence between people's use of the concept of _intention_ and their use of the concept of _acting intentionally_. It seems that people's application of the concept of intention is determined by their beliefs about the agent's psychological states whereas their use of the concept of acting intentionally is determined at least in part by their beliefs about the moral status of the behavior itself (i.e., by their beliefs about whether the behavior is morally good (...) or morally bad). These findings raise a number of difficult questions about the relationship between the concept of intention and the concept of acting intentionally. The present paper addresses those questions using a variety of different methods, including conceptual analysis, psychological experimentation, and an examination of people's use of certain expressions in other languages.

Moral philosophers, legal theorists, and psychologists who study moral judgment are remarkably agreed in prescribing how to blame people. A blameworthy act occurs when an actor intentionally, negligently or recklessly causes foreseen, or foreseeable, harmful consequences without any compelling mitigating or extenuating circumstances. This simple formulation conveniently forestalls intricacies about how to construe concepts such as will, causation, foresight, and mitigation, but putting that aside for the moment, it seems fair to say that blame “professionals” share compatible conceptions of how (...) to make fair and rational blame ascriptions. Blame “amateurs,” on the other hand, sometimes stretch these rational prescriptions for blame beyond the breaking point. Numerous psychological studies on blame and responsibility, as well as the perplexing outcomes of high-profile criminal and civil trials, demonstrate that everyday blamers are capable of violating virtually every rational prescription that moral philosophers, legal scholars, and rational decision theorists hold dear.

Is intentionally doing A linked to the intention to do A? Knobe and Burra believe that the link between the English words ‘intention’ and ‘intentional’ may mislead philosophers and cognitive scientists to falsely believe that intentionally doing an action A requires one to have the intention to do A. Knobe and Burra believe that data from other languages..

Among philosophers, there are at least two prevalent views about the core concept of intentional action. View I (Adams 1986, 1997; McCann 1986) holds that an agent S intentionally does an action A only if S intends to do A. View II (Bratman 1987; Harman 1976; and Mele 1992) holds that there are cases where S intentionally does A without intending to do A, as long as doing A is foreseen and S is willing to accept A as a consequence (...) of S’s action. Joshua Knobe (2003a) presents intriguing data that may be taken to support the second view.1 Knobe’s data show an asymmetry in folk judgements. People are more inclined to judge that S did A intentionally, even when not intended, if A was perceived as causing a harm (e.g. harming the environment). There is an asymmetry because people are not inclined to see S’s action as intentional, when not intended, if A is perceived as causing a benefit (e.g. helping the environment). In this paper we will discuss Knobe’s results in detail. We will raise the question of whether his ordinary language surveys of folk judgments have accessed core concepts of intentional action. We suspect that instead Knobe’s surveys are tapping into pragmatic aspects of intentional language and its role in moral praise and blame. We will suggest alternative surveys that we plan to conduct to get at this difference, and we will attempt to explain the pragmatic usage of intentional language. (shrink)

Studies of normal individuals reveal an asymmetry in the folk concept of intentional action: an action is more likely to be thought of as intentional when it is morally bad than when it is morally good. One interpretation of these results comes from the hypothesis that emotion plays a critical mediating role in the relationship between an action’s moral status and its intentional status. According to this hypothesis, the negative emotional response triggered by a morally bad action drives the attribution (...) of intent to the actor, or the judgment that the actor acted intentionally. We test this hypothesis by presenting cases of morally bad and morally good action to seven individuals with deficits in emotional processing resulting from damage to the ventromedial prefrontal cortex (VMPC). If normal emotional processing is necessary for the observed asymmetry, then individuals with VMPC lesions should show no asymmetry. Our results provide no support for this hypothesis: like normal individuals, those with VMPC lesions showed the same asymmetry, tending to judge that an action was intentional when it was morally bad but not when it was morally good. Based on this finding, we suggest that normal emotional processing is not responsible for the observed asymmetry of intentional attributions and thus does not mediate the relationship between an action’s moral status and its intentional status.

Abstract: Recent experimental research on the 'Knobe effect' suggests, somewhat surprisingly, that there is a bi-directional relation between attributions of intentional action and evaluative considerations. We defend a novel account of this phenomenon that exploits two factors: (i) an intuitive asymmetry in judgments of responsibility (e.g. praise/blame) and (ii) the fact that intentionality commonly connects the evaluative status of actions to the responsibility of actors. We present the results of several new studies that provide empirical evidence in support of this (...) account while disconfirming various currently prominent alternative accounts. We end by discussing some implications of this account for folk psychology. (shrink)

In this paper we propose to argue for two claims. The first is that a sizeable group of epistemological projects – a group which includes much of what has been done in epistemology in the analytic tradition – would be seriously undermined if one or more of a cluster of empirical hypotheses about epistemic intuitions turns out to be true. The basis for this claim will be set out in Section 2. The second claim is that, while the jury is (...) still out, there is now a substantial body of evidence suggesting that some of those empirical hypotheses are true. Much of this evidence derives from an ongoing series of experimental studies of epistemic intuitions that we have been conducting. A preliminary report on these studies will be presented in Section 3. In light of these studies, we think it is incumbent on those who pursue the epistemological projects in question to either explain why the truth of the hypotheses does not undermine their projects, or to say why, in light of the evidence we will present, they nonetheless assume that the hypotheses are false. In Section 4, which is devoted to Objections and Replies, we’ll consider some of the ways in which defenders of the projects we are criticizing might reply to our challenge. Our goal, in all of this, is not to offer a conclusive argument demonstrating that the epistemological projects we will be criticizing are untenable. Rather, our aim is to shift the burden of argument. (shrink)

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)

The traditional philosophical doctrine of double effect claims that agents’ intentions affect whether acts are morally wrong. Our behavioral study reveals that agents’ intentions do affect whether acts are judged morally wrong, whereas the temporal order of good and bad effects affects whether acts are classified as killings. This finding suggests that the moral judgments are not based on the classifications. Our results also undermine recent claims that prior moral judgments determine whether agents are seen as causing effects intentionally rather (...) than as side effects. (shrink)

Recent and puzzling experimental results suggest that people’s judgments as to whether or not an action was performed intentionally are sensitive to moral considerations. In this paper, we outline these results and evaluate two accounts which purport to explain them. We then describe a recent experiment that allegedly vindicates one of these accounts and present our own findings to show that it fails to do so. Finally, we present additional data suggesting no such vindication could be in the offing and (...) that, in fact, both accounts fail to explain the initial, puzzling results they were purported to explain.

In this paper, I first review some of the recent empirical work on the biasing effect that moral considerations have on folk ascriptions of intentional action. Then, I use Mark Alicke's affective model of blame attribution to explain this biasing effect. Finally, I discuss the relevance of this research - both philosophical and psychological - to the problem of the partiality of jury deliberation. After all, if the immorality of an action does affect folk ascriptions of intentionality, and all serious (...) criminal offenses - e.g., murder and rape - are immoral in addition to being illegal, then a juror's ability to determine the relevant mens rea (i.e., guilty mind) of a defendant in an unbiased way may be seriously undermined.

We argue, contrary to epistemological orthodoxy, that knowledge is not purely epistemic—that knowledge is not simply a matter of truth‐related factors (evidence, reliability, etc.). We do this by arguing for a pragmatic condition on knowledge, KA: if a subject knows that p, then she is rational to act as if p. KA, together with fallibilism, entails that knowledge is not purely epistemic. We support KA by appealing to the role of knowledge‐citations in defending and criticizing actions, and by giving a (...) principled argument for KA, based on the inference rule KB: if a subject knows that A is the best thing she can do, she is rational to do A. In the second half of the paper, we consider and reject the two most promising objections to our case for KA, one based on the Gricean notion of conversational implicature and the other based on a contextualist maneuver.

Recent empirical work calls into question the so-called Simple View that an agent who A’s intentionally intends to A. In experimental studies, ordinary speakers frequently assent to claims that, in certain cases, agents who knowingly behave wrongly intentionally bring about the harm they do; yet the speakers tend to deny that it was the intention of those agents to cause the harm. This paper reports two additional studies that at first appear to support the original ones, but argues that in (...) fact, the evidence of all the studies considered is best understood in terms of the Simple View.

This article explores several entanglements between human judgments of intentionality and morality (blame and praise). After proposing a model of people’s folk concept of intentionality I discuss three topics. First, considerations of a behavior’s intentionality a ff ect people’s praise and blame of that behavior, but one study suggests that there may be an asymmetry such that blame is more affected than praise. Second, the concept of intentionality is constitutive of many legal judgments (e.g., of murder vs. manslaughter), and one (...) study illustrates people’s subtle considerations of intentionality in making those judgments. Third, controversial recent studies suggest that moral considerations can affect judgments of intentionality, and an asymmetry may exist such that blame a ff ects those judgments more than praise. I report two new studies that may shed light on these recent findings, and I discuss several theoretical models that might account for the impact of moral considerations on intentionality judgments and for the relationship between the two more generally.

Recent work by Joshua Knobe has established that people are more likely to describe bad but foreseen side‐effects as intentionally performed than good but foreseen side‐effects (this is sometimes called the ‘Knobe effect’ or the ‘side‐effect effect’. Edouard Machery has proposed a novel explanation for this asymmetry: it results from construing the bad side‐effect as a cost that must be incurred to receive a benefit. In this paper, I argue that Machery’s ‘trade‐off hypothesis’ is wrong. I do this by reproducing (...) the asymmetry between judgments about good and bad side‐effects in cases that cannot plausibly be construed as trade‐offs. (shrink)

Recent experimental fi ndings by Knobe and others ( Knobe, 2003; Nadelhoffer, 2006b; Nichols and Ulatowski, 2007 ) have been at the center of a controversy about the nature of the folk concept of intentional action. I argue that the signifi cance of these fi ndings has been overstated. My discussion is two-pronged. First, I contend that barring a consensual theory of conceptual competence, the signifi cance of these experimental fi ndings for the nature of the concept of intentional action (...) cannot be determined. Unfortunately, the lack of progress in the philosophy of concepts casts doubt on whether such a consensual theory will be found. Second, I propose a new, defl ationary interpretation of these experimental fi ndings, ‘ the trade-off hypothesis ’ , and I present several new experimental fi ndings that support this interpretation.

There has been a long-standing dispute in the philosophical literature about the conditions under which a behavior counts as 'intentional.' Much of the debate turns on questions about the use of certain words and phrases in ordinary language. The present paper investigates these questions empirically, using experimental techniques to investigate people's use of the relevant words and phrases. g.

People ordinarily make sense of their own behavior and that of others by invoking concepts like belief, desire, and intention. Philosophers refer to this network of concepts and related principles as 'folk psychology.' The prevailing view of folk psychology among philosophers of mind and psychologists is that it is a proto-scientific theory whose function is to explain and predict behavior.

Consider the following explanation: (1) George took his umbrella because it was just about to rain. This is an explanation of a quite distinctive sort. It is profoundly different from the sort of explanation we might use to explain, say, the movements of a bouncing ball or the gradual rise of the tide on a beach. Unlike these other types of explanations, it explains an agent’s behavior by describing the agent’s own _reasons_ for performing that behavior. Explanations that work in (...) this way have a number of distinctive and important properties, and we will refer to them here as _reason explanations_. Looking at the use of reason explanations with a philosophical eye, one is apt to experience a certain puzzlement. One wants to know precisely what makes a given reason explanation true or false. So, for example, the explanation given above seems to be saying that George’s reason for taking his umbrella was that it was just about to rain. But what exactly makes it the case that this is George’s reason? Does he have to actually be. (shrink)

It is often implied, and sometimes explicitly asserted, that folk psychology is best understood as a kind of predictive device. The key contention of this widely held view is that people apply folk-psychological concepts because the application of these concepts enables them to predict future behavior. If we know what an agent believes, desires, intends, etc., we can make a pretty good guess about what he or she will do next. It seems to me that this picture is not quite (...) right. In a series of recent papers, my colleagues and I have presented data that suggests that moral considerations actually play an important role in folk psychology (Knobe 2003a; 2003b; 2004; Knobe & Burra forthcoming; Knobe & Mendlow forthcoming). These findings do not sit well with the view according to which folk psychology is best understood as a predictive device. It appears that folk psychology might be better understood as a kind of multi-purpose tool. It is used not only in making predictive judgments but also in making moral judgments, and both of these uses appear to have shaped the fundamental competencies that underlie it. One of the most important forms of evidence in this debate comes from studies of the distinction people draw between intentional and unintentional behavior. These studies indicate that people’s intuitions as to whether or not a behavior was performed intentionally can be influenced by their beliefs about the moral status of the behavior.. (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)

The concept of acting intentionally is an important nexus where ‘theory of mind’ and moral judgment meet. Preschool children’s judgments of intentional action show a valence-driven asymmetry. Children say that a foreseen but disavowed side-effect is brought about 'on purpose' when the side-effect itself is morally bad but not when it is morally good. This is the first demonstration in preschoolers that moral judgment influences judgments of ‘on-purpose’ (as opposed to purpose influencing moral judgment). Judgments of intentional action are usually (...) assumed to be purely factual. That these judgments are sometimes partly normative — even in preschoolers — challenges current understanding. Young children’s judgments regarding foreseen side-effects depend upon whether the children process the idea that the character does not care about the side-effect. As soon as preschoolers effectively process the ‘theory of mind’ concept, NOT CARE THAT P, children show the side-effect effect.idea.. (shrink)

Throughout the 20th century, an enormous amount of intellectual fuel was spent debating the merits of a class of skeptical arguments which purport to show that knowledge of the external world is not possible. These arguments, whose origins can be traced back to Descartes, played an important role in the work of some of the leading philosophers of the 20th century, including Russell, Moore and Wittgenstein, and they continue to engage the interest of contemporary philosophers. (e.g., Cohen 1999, DeRose 1995, (...) Hill 1996, Klein 1981, Lewis 1996, McGinn 1993, Nozick 1981, Schiffer 1996, Unger 1975, Williams 1996) Typically, these arguments make use of one or more premises which the philosophers proposing them take to be intuitively obvious. Beyond an appeal to intuition, little or no defense is offered, and in many cases it is hard to see what else could be said in support of these premises. A number of authors have suggested that the intuitions undergirding these skeptical arguments are universal – shared by everyone (or almost everyone) who thinks reflectively about knowledge. In this paper we will offer some evidence indicating that they are far from universal. Rather, the evidence suggests that many of the intuitions epistemologists invoke vary with the cultural background, socioeconomic status and educational background of the person offering the intuition. And this, we will argue, is bad news for the skeptical arguments that rely on those intuitions. The evidence may also be bad news for skepticism itself – not because it shows that skepticism is false, but rather because, if we accept one prominent account of the link between epistemic intuitions and epistemic concepts, it indicates that skepticism may be much less interesting and much less worrisome than philosophers have taken it to be.

What are the criteria people use when they judge that other people did something intentionally? This question has motivated a large and growing literature both in philosophy and in psychology. It has become a topic of particular concern to the nascent field of experimental philosophy, which uses empirical techniques to understand folk concepts.
