Added by: Giada FratantonioAbstract:
Introduction: This article discusses expected utility theory as a normative theory - that is, a theory of how people should make decisions. In classical economics, expected utility theory is often used as a descriptive theory - that is, a theory of how people do make decisions - or as a predictive theory - that is, a theory that, while it may not accurately model the psychological mechanisms of decision-making, correctly predicts people's choices. Expected utility theory makes faulty predictions about people's decisions in many real-life choice situations (see Kahneman & Tversky 1982); however, this does not settle whether people should make decisions on the basis of expected utility considerations. The expected utility of an act is a weighted average of the utilities of each of its possible outcomes, where the utility of an outcome measures the extent to which that outcome is preferred, or preferable, to the alternatives. The utility of each outcome is weighted according to the probability that the act will lead to that outcome. Section 1 fleshes out this basic definition of expected utility in more rigorous terms, and discusses its relationship to choice. Section 2 discusses two types of arguments for expected utility theory: representation theorems, and long-run statistical arguments. Section 3 considers objections to expected utility theory; section 4 discusses its applications in philosophy of religion, economics, ethics, and epistemology.

Added by: Jie GaoAbstract: Contextualists such as Cohen and DeRose claim that the truth conditions of knowledge attributions vary contextually, in particular that the strength of epistemic position required for one to be truly ascribed knowledge depends on features of the attributor's context. Contextualists support their view by appeal to our intuitions about when it's correct (or incorrect) to ascribe knowledge. Someone might argue that some of these intuitions merely reflect when it is conversationally appropriate to ascribe knowledge, not when knowledge is truly ascribed, and so try to accommodate these intuitions even on an invariantist view. DeRose (Blackwell Guide to Epistemology, 1998; Philosophical Review, 2002) argues that any such 'warranted assertibility manoeuvre', or 'WAM', against contextualism is unlikely to succeed. Here, I argue that his objections to a WAM against contextualism are not persuasive and offer a pragmatic account of the data about ascriptions of knowledge.Comment: This paper defends the warranted assertibility manoeuvres, a prominent pragmatic criticism to epistemic contextualism. It is useful as a central or a further reading material for teachings on contextualism in an upper-level undergraduate course on epistemology.

Added by: Jie GaoAbstract: I will ask the conditional question: if folk attributions of "know" are not sensitive to the stakes and/or the salience of error, does this cast doubt on contextualism or subject-sensitive invariantism (SSI)? I argue that if it should turn out that folk attributions of knowledge are insensitive to such factors, then this undermines contextualism, but not SSI. That is not to say that SSI is invulnerable to empirical work of any kind. Rather, I defend the more modest claim that leading versions of SSI are not undermined by one particular kind of experimental result, namely the recent suggestion that knowledge attributions are insensitive to the stakes.Comment: Suitable for an upper-level undergraduate course on epistemology for multiple purposes. It is good as a further reading for sessions on contextualism, pragmatic encroachment, philosophical methodology, and the use of experimental philosophy in epistemological theorizing.

Added by: Jie GaoIntroduction: It is increasingly popular to suggest that knowledge is the norm of practical reasoning, or reasoning about what to do (e.g. Hawthorne 2004, Stanley 2005). This idea is central to the defence of a new version of invariantism - 'subject-sensitive invariantism' - on which whether the true belief that p is knowledge not only depends on such factors as one's evidence, and the reliability of the belief-producing process, but also the stakes or how important it is that p be true (the view is also known as 'sensitive moderate invariantism' (Hawthorne 2004) and 'interest relative invariantism' (Stanley 2005)). I will argue against the idea that knowledge is the norm of practical reasoning, whether that is understood as a necessity or sufficiency claim. Instead, I will argue that the epistemic standards for practical reasoning vary contextually.Comment: This paper nicely elucidates the debates on pragmatic encroachment in epistemology and presents main objections to the knowledge norm of practical reasoning. It is useful for teachings on pragmatic encroachment and the knowledge norm of practical reasoning in an upper-level undergraduate course on epistemology.

Added by: Giada Fratantonio, Nick NovelliPublisher'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.Comment: A very interesting defense of anti-individualism. Contains interesting discussion on the topics of semantic externalism and introspection. Sections of it could be taught in any epistemology course covering these topics.

Added by: Emily PaulAbstract: It is sometimes said that faith is recalcitrant in the face of new evidence, but it is puzzling how such recalcitrance could be rational or laudable. I explain this aspect of faith and why faith is not only rational, but in addition serves an important purpose in human life. Because faith requires maintaining a commitment to act on the claim one has faith in, even in the face of counter-evidence, faith allows us to carry out long-term, risky projects that we might otherwise abandon. Thus, faith allows us to maintain integrity over time.Comment: This would be a great paper to set for further reading, with Buchak's 'Can it be Rational to Have Faith'? as a primary reading. It could alternatively be a primary reading, but in a more specialised Philosophy of Religion course - for instance, one that is specifically on Religious Epistemology or on Faith and Reason.

Added by: Emily PaulAbstract: This paper provides an account of what it is to have faith in a proposition p, in both religious and mundane contexts. It is argued that faith in p doesn't require adopting a degree of belief that isn't supported by one's evidence but rather it requires terminating one's search for further evidence and acting on the supposition that p. It is then shown, by responding to a formal result due to I.J. Good, that doing so can be rational in a number of circumstances. If expected utility theory is the correct account of practical rationality, then having faith can be both epistemically and practically rational if the costs associated with gathering further evidence or postponing the decision are high. If a more permissive framework is adopted, then having faith can be rational even when there are no costs associated with gathering further evidenceComment: A great paper for an intermediate philosophy of religion course, especially because many arguments from students are to the contrary: it's irrational to believe in God when we don't have satisfactory evidence. It could be nice to set up a debate centering around this paper. It could work particularly well towards the end of the course.

Added by: Emily PaulAbstract: In 'Can it be rational to have faith?', it was argued that to have faith in some proposition consists, roughly speaking, in stopping one's search for evidence and committing to act on that proposition without further evidence. That paper also outlined when and why stopping the search for evidence and acting is rationally required. Because the framework of that paper was that of formal decision theory, it primarily considered the relationship between faith and degrees of belief, rather than between faith and belief full stop. This paper explores the relationship between rational faith and justified belief, by considering four prominent proposals about the relationship between belief and degrees of belief, and by examining what follows about faith and belief according to each of these proposals. It is argued that we cannot reach consensus concerning the relationship between faith and belief at present because of the more general epistemological lack of consensus over how belief relates to rationality: in particular, over how belief relates to the degrees of belief it is rational to have given one's evidence.Comment: This could be a great paper to set for further reading, with Buchak's 'Can it be Rational to Have Faith?' as a primary reading. If being discussed as a primary reading, it would be good to get very clear on Buchak's four candidates for the relationship between belief and degrees of belief: perhaps by splitting the room into four groups, and getting each group to discuss one proposal - as well as what follows about the relationship between faith and belief according to that proposal.

Added by: Jie GaoPublisher's Note: Lara Buchak sets out a new account of rational decision-making in the face of risk. She argues that the orthodox view is too narrow, and suggests an alternative, more permissive theory: one that allows individuals to pay attention to the worst-case or best-case scenario, and vindicates the ordinary decision-maker.Comment: This book argues for an alternative account of ideal rationality as opposed to the orthodox view in terms of expected utility theory. Buchak manages to explain the technical details of her theory in such a non-technical way that any student of philosophy will be able to follow her discussion. The book moreover contains very interesting passages on what we might call "the philosophy of decision theory", such as metaphysical and epistemological issues concerning utilities and probabilities. This makes it a good teaching material for courses on decision theory and philosophy of action.
