Cooperation can evolve in the context of cognitive activities such as perception, attention, memory, and decision making, in addition to physical activities such as hunting, gathering, warfare, and childcare. The social insects are well known to cooperate on both physical and cognitive tasks, but the idea of cognitive cooperation in humans has not received widespread attention or systematic study. The traditional psychological literature often gives the impression that groups are dysfunctional cognitive units, while evolutionary psychologists have so far studied cognition (...) primarily at the individual level. We present two experiments that demonstrate the superiority of thinking in groups, but only for tasks that are sufficiently challenging to exceed the capacity of individuals. One of the experiments is in a brain-storming format, where advantages of real groups over nominal groups have been notoriously difficult to demonstrate. Cognitive cooperation might often operate beneath conscious awareness and take place without the need for overt training, as evolutionary psychologists have stressed for individual-level cognitive adaptations. In general, cognitive cooperation should be a central subject in human evolutionary psychology, as it already is in the study of the social insects. (shrink)

This book gives a general theory of rational belief. Although it can be read by itself, is a sequel to the author's previous book The Value of Rationality (Oxford, 2017). It takes the general conception of rationality that was defended in that earlier book, and combines it with an account of the varieties of belief, and of what it is for these beliefs to count as "correct", to develop an account of what it is for beliefs to count as rational. (...) According to this account, rationality comes in degrees: the degree to which one's beliefs counts as rational is determined by their distance from a corresponding probability function - where this distance is measured by those beliefs' "expected degree of incorrectness" according to the probability function; the account also involves an explanation of what determines exactly which probability function plays this role in each case, and of why this probability function should play this role. In developing and defending this account, new light is shed on several central epistemological issues. These issues include: the distinction between propositional and doxastic justification; the debates between internalism and externalism, and between foundationalism and coherentism; the significance - or lack of it - of the notion of 'evidence'; the relationship between credences, full belief, inference, and suspension of judgment; the nature of the kind of possibility that is presupposed by the relevant sort of probability; and whether rationality is "diachronic" - so that the beliefs that it is rational for us to have now depend, in part, on the beliefs that we held in the past. Finally, some suggestions are made about how this theory bears on a range of further topics, including the defeasibility of inference, scepticism, and the analysis of knowledge. (shrink)

Sometimes, we think of belief as a phenomenon that comes in degrees – that is, in the many different levels of confidence that a thinker might have in various different propositions. Sometimes, we think of belief as a simple two-place relation that holds between a thinker and a proposition – that is, as what I shall here call "outright belief".

Many philosophers working on the branches of philosophy that deal with the normative questions have adopted a " Reasons First" program. This paper criticizes the foundational assumptions of this program. In fact, there are many different concepts that can be expressed by the term 'reason' in English, none of which are any more fundamental than any others. Indeed, most of these concepts are not particularly fundamental in any interesting sense.

If beliefs are subject to a basic norm of correctness—roughly, to the principle that a belief is correct only if the proposition believed is true—how can this norm guide believers in forming their beliefs? Answer: this norm guides believers indirectly: believers are directly guided by requirements of rationality—which are themselves explained by this norm of correctness. The fundamental connection between rationality and correctness is probabilistic. Incorrectness comes in degrees; for beliefs, these degrees of incorrectness are measured by quadratic scoring rules, (...) such as the so-called Brier score. This account is defended against objections; and its implications for suspension of judgement are explored. (shrink)

Every kind of ‘ought’ implies some kind of ‘can’ – but there are many kinds of ‘ought’ and even more kinds of ‘can’. In this essay, I shall focus on a particular kind of ‘ought’ – specifically, on what I shall call the “rational ‘ought’”. On every occasion of use, this kind of ‘ought’ is focused on the situation of a particular agent at a particular time; but this kind of ‘ought’ is concerned, not with how that agent acts at (...) that time, but with what beliefs or intentions the agent has at the time, or with the sort of reasoning by means of which the agent at that time forms or revises those beliefs or intentions.

According to John Broome, akrasia consists in a failure to intend to do something that one believes one ought to do, and such akrasia is necessarily irrational. In fact, however, failing to intend something that one believes one ought to do is only guaranteed to be irrational if one is certain of a maximally detailed proposition about what one ought to do; if one is uncertain about any part of the full story about what one ought to do, it could (...) be perfectly rational not to intend to do something that one believes one ought to do. This paper seeks to remedy this problem, by proposing an anti-akrasia principle that covers cases of uncertainty (as well as cases of such complete certainty). It is argued that this principle is in effect the fundamental principle of practical rationality. (shrink)

Despite enthusiasm for patient-centered care, the practice of patient-centered care is proving challenging. Further, it is curious that the literature about this subject does not explicitly address patient autonomy, since patients guide care in patient-centered care, and respect for patient autonomy is a prominent health-care value. We argue that by explicitly adopting a relational conception of autonomy as an essential component, patient-centered care becomes more coherent, is strengthened, and could help practitioners to make better use of a principle of respect (...) for autonomy. Hence, its use appears promising to narrow the theory–practice gap. (shrink)

The aim of this chapter is to defend the claim that “the intentional is normative” against a number of objections, including those that Georges Rey has presented in his contribution to this volume. First, I give a quick sketch of the principal argument that I have used to support this claim, and briefly comment on Rey’s criticisms of this argument. Next, I try to answer the main objections that have been raised against this claim. First, it may seem that the (...) claim that “the intentional is normative” is just hopelessly Panglossian: doesn’t this claim just wilfully ignore all the mountains of evidence that we have for the sheer ubiquity and pervasiveness of human irrationality? Secondly, the claim that intentional mental states are essentially normative seems to be intended as a purely philosophical, non-empirical account of the nature of these mental states: but why should we think that purely philosophical reflection can tell us anything interesting about the nature of the mind -- shouldn’t we look to empirical psychology to enlighten us about such matters? I argue that neither of these objections succeeds in undermining my version of the claim that "the intentional is normative". (shrink)

This essay explores the following position: Ultimate moral principles are a priori truths; hence, it is irrational to assign a non-zero credence to any proposition that is incompatible with these ultimate moral principles ; and this sort of irrationality, if it could have been avoided, is in a sense inexcusable. So—at least if moral relativism is false—in any disagreement about ultimate moral principles, at least one party to the disagreement is inexcusably irrational. This position may seem extreme, but it is (...) argued that it is more plausible than it first appears. (shrink)

According to a widely held view of the matter, whenever we assess beliefs as ‘rational’ or ‘justified’, we are making normative judgements about those beliefs. In this discussion, I shall simply assume, for the sake of argument, that this view is correct. My goal here is to explore a particular approach to understanding the basic principles that explain which of these normative judgements are true. Specifically, this approach is based on the assumption that all such normative principles are grounded in (...) facts about values, and the normative principles that apply to beliefs in particular are grounded in facts about alethic value––a kind of value that is exemplified by believing what is true and not believing what is false. In this chapter, I shall explain what I regard as the best way of interpreting this approach. In doing so, I shall also show how this interpretation can solve some problems that have recently been raised for approaches of this kind by Selim Berker, Jennifer Carr, Michael Caie, and Hilary Greaves.

What is normativity? It is argued here that normativity is best understood as a property of certain concepts: normative thoughts are those involving these normative concepts; normative statements are statements that express normative thoughts; and normative facts are the facts (if such there be) that make such normative thoughts true. Many philosophers propose that there is a single basic normative concept—perhaps the concept of a reason for an action or attitude—in terms of which all other normative concepts can be defined. (...) It is argued here that this proposal faces grave difficulties. According to a better proposal, what these normative concepts have in common is that they have a distinctive sort of conceptual role—a reasoning-guiding conceptual role. This proposal is illustrated by a number of examples: different normative concepts differ from each other in virtue of their having different conceptual roles of this reasoning-guiding kind.

Many philosophers have thought that colours or flavours or values are in some way less objective than shape or mass or motion. This paper explores the approach to capturing this thought that is based on the idea of ‘ response-dependence ’. First, it is argued that the conceptions of response-dependence developed by Mark Johnston, Philip Pettit and Crispin Wright fail to capture this thought adequately. Then, the rest of the paper proposes an alternative conception, based in part on Kit Fine's (...) notion of " essence ", which looks more likely to succeed in capturing the thought adequately.

Eighteenth-century England saw the rise of a "peculiarly English" art form—landscape gardening—and a corresponding change in attitudes toward the antural world. While the French, who lived under tyranny, had a tightly organized, restrictive gardens, the "free" English enjoyed gardens where they were at liberty to wander. John Dixon Hunt examines eighteenth-century letters, literary and critical works, biographies, paintings, prints, and drawings to trace the gradual movement from formal regularity toward a carefully calculated naturalness.

There is not only moral disagreement among ordinary people: there is also moral disagreement among philosophers. Since philosophers might seem to be in the best possible position to reach the truth about morality, such disagreement may suggest that either there is no single truth about morality, or at least if there is, it is unknowable. The goal of this paper is to rebut this argument: the best explanation of moral disagreement among philosophers is quite compatible with the thesis that many (...) moral truths are widely known.

This paper explores how undergraduate students understood the social relevance of their engineering course content knowledge and drew broader social and ethical implications from that knowledge. Based on a three-year qualitative study in a junior-level engineering class, we found that students had difficulty in acknowledging the social and ethical aspects of engineering as relevant topics in their coursework. Many students considered the immediate technical usability or improved efficiency of technical innovations as the noteworthy social and ethical implications of engineering. Findings (...) suggest that highly-structured engineering programs leave little room for undergraduate students to explore the ethical dimension of engineering content knowledge and interact with other students/programs on campus to expand their “technically-minded” perspective. We discussed the issues of the “culture of disengagement” :42–72, 2014) fueled by disciplinary elitism, spatial distance, and insulated curriculum prevalent in the current structure of engineering programs. We called for more conscious effort by engineering educators to offer meaningful interdisciplinary engagement opportunities and in-class conversations on ethics that support engineering students' holistic intellectual growth and well-rounded professional ethics.

This paper defends the institution of civil marriage against the objection that it is inconsistent with political liberalism, and so should be either totally abolished or else transformed virtually beyond recognition.

There are three well-known models of how to account for perceptual belief within a probabilistic framework: (a) a Cartesian model; (b) a model advocated by Timothy Williamson; and (c) a model advocated by Richard Jeffrey. Each of these models faces a problem—in effect, the problem of accounting for the defeasibility of perceptual justification and perceptual knowledge. It is argued here that the best way of responding to this the best way of responding to this problem effectively vindicates the Cartesian model. (...) Finally, it is argued that, given the best interpretation of the probabilistic framework, that the Cartesian model is not vulnerable to the main criticisms that have been raised against it. (shrink)

An account of Plato’s theory of knowledge is offered. Plato is in a sense a contextualist: at least, he recognizes that his own use of the word for “knowledge” varies – in some contexts, it stands for the fullest possible level of understanding of a truth, while in other contexts, it is broader and includes less complete levels of understanding as well. But for Plato, all knowledge, properly speaking, is a priori knowledge of necessary truths – based on recollection of (...) aspects of the Forms – and so in contemporary terms, it meets the conditions of “safety” and “adherence” (or “indefeasibility”) to the highest degree. This account is defended on the basis of the text of Meno, Phaedo, and the Republic, against some objections – especially objections that are due to Gail Fine. (shrink)

This paper starts by giving an interpretation of the notorious question "Why be moral?" Then, to answer that question, it develops an account of why some moral reasons -- specifically, the moral reasons that ground moral requirements -- are sufficiently weighty that they outweigh all countervailing reasons for action.

It is widely assumed that our “evidence” is at least one source of the “justification” that we have for believing things—where this notion of “justification” seems to be a normative notion. More precisely, it seems to be an agential normative notion, evaluating the different possible attitudes that are available to an agent at a time, on the basis of facts that are just “given”—that is, facts that it is not available to the agent to change through the way in which (...) she exercises her reasoning capacities at that time. However, given the meaning that the term “evidence” has in everyday English, what is in this sense “given” to you cannot be identified with your current “evidence”. First, some propositions count as part of the “evidence” that you now have precisely in virtue of the fact that you now believe those propositions; but these beliefs are not part of what is now “given” to you—they are themselves among the attitudes whose justification is in question. Secondly, what is now “given” to you arguably includes facts about what you believed in the past—but such facts cannot naturally be called part of your current “evidence” unless you now know or believe these facts. In fact, it seems, the concept “evidence” does not really belong to individualistic epistemology, but to social epistemology: the function of “evidence” is that it is what we can use to show that something is true to the contextually relevant audience.

Nonreductive physicalism faces a serious objection: physicalism entails the existence of an enormous number of modal facts--specifically, facts about exactly which physical properties necessitate each mental property; and, it seems, if mental properties are irreducible, these modal facts cannot all be satisfactorily explained. The only answer to this objection is to claim that the explanations of these modal facts are themselves contingent. This claim requires rejecting "S5" as the appropriate logic for metaphysical modality. Finally, it is argued that rejecting "S5" (...) is not too high a price to pay for nonreductive physicalism: "S5" should probably be rejected anyway. (shrink)

New mechanisms to ensure that counter ter ror ism ac t ivit ies do not contravene international law or ethical values and principles will require careful design. Apart from the ethical and legal grounds, there are good practical rea-sons to design more effective counterter-rorism measures. Preventable harms to population health contribute to mistrust and instability and undermine the stated objectives of the intelligence services.

How can women’s rights be seen as a universal value rather than a Western value imposed upon the rest of the world? Addressing this question, Eileen Hunt Botting offers the first comparative study of writings by Mary Wollstonecraft and John Stuart Mill. Although Wollstonecraft and Mill were the primary philosophical architects of the view that women’s rights are human rights, Botting shows how non-Western thinkers have revised and internationalized their original theories since the nineteenth century. Botting explains why this (...) revised and internationalized theory of women’s human rights—grown out of Wollstonecraft and Mill but stripped of their Eurocentric biases—is an important contribution to thinking about human rights in truly universal terms.

This is a review of Ruth Garrett Millikan's 1993 book, White Queen Psychology and Other Essays for Alice.

This essay champions the idea of substances, understood as things that can exist by themselves. I argue that this idea has a valuable role to play in present-day philosophy, in explaining what makes object-like things object-like, and an important place in the history of philosophy, from its roots in Aristotle to its full expression in Descartes. Both claims are unusual. For philosophers tend to regard the idea of something that could exist by itself as incoherent, and this has encouraged the (...) view that it will be useless to present-day philosophers and that it cannot charitably be attributed to Descartes. I argue that the charge of incoherence rests on a misunderstanding. I also address various other objections to the idea of substances as things that can exist by themselves. (shrink)

This paper offers an account of the a priori. According to this account, the fundamental notion is not that of a priori knowledge, or even of a priori justified belief, but a notion of an a priori justified inferential disposition. The rationality or justification of such a priori justified inferential dispositions is explained purely by some of the basic cognitive capacities that the thinker possesses, independently of any further experiences or other conscious mental states that the thinker happens to have (...) had. It is then shown how a priori justified inferences and beliefs can be explained on the basis of such a priori justified inferential dispositions. (shrink)

Normal agents in the actual world are limited: they cannot think about all the options that are available to them—or even about all options that are available to them according to their evidence. Moreover, agents cannot choose an option unless they have thought about that option. Such agents can be irrational in two ways: either by making their choice too quickly, without canvassing enough options, or by wasting time canvassing ever more options when they have already thought of enough options. (...) This chapter proposes an account of this kind of rationality for limited agents. To be rational, such agents need a kind of background sensitivity to whether or not continuing to search for more options has greater expected value than deciding right away. According to this proposal, it is the unavoidable predicament of choice that all rational decision-making depends on the unconscious operation of mental dispositions. (shrink)

This is a discussion of Mark Schroeder’s book Reasons First. In this book, Schroeder defends the following thesis: for every believer and every time, it is the reasons that the believer has at that time that determine what it is rational for the believer to believe at that time. It is argued here that this thesis is false, since it conflicts with the plausible principle of “normative invariance”: what a believer ought to believe at a time cannot depend on what (...) the believer actually believes at that time. Schroeder’s thesis conflicts with this principle because Schroeder accepts that what reasons a believer has at a time always depends, at least in part, on the beliefs that the believer has at the time. The conclusion to be drawn is that, if this principle of normative invariance is correct, the notions of “reasons” and “evidence” should be banished from fundamental epistemology. (shrink)

The current humanitarian use of drones is focused on two applications: disaster mapping and medical supply delivery. In response to the growing interest in drone deployment in the aid sector, we sought to develop a resource to support value sensitivity in humanitarian drone activities. Following a bottom-up approach encompassing a comprehensive literature review, two empirical studies, a review of guidance documents, and consultations with experts, this work illuminates the nature and scope of ethical challenges encountered by humanitarian organizations embarking upon (...) innovation programmes. The Framework for the Ethics Assessment of Humanitarian Drones (FEAHD) identifies five values and five key questions related to ethical considerations along the decision chain of humanitarian drone activities. It fills a gap between high-level, principle-based guidance related to humanitarian innovation, and detailed operation-oriented checklists for projects involving the use of drones. In this way, the FEAHD contributes to support value sensitivity in the humanitarian use of drones. (shrink)
