This paper sketches a general account of how to respond in an epistemically rational way to moral disagreement. Roughly, the account states that when two parties, A and B, disagree as to whether p, A says p while B says not-p, this is higher-order evidence that A has made a cognitive error on the first-order level of reasoning in coming to believe that p (and likewise for B with respect to not-p). If such higher-order evidence is not defeated, then one (...) rationally ought to reduce one’s confidence with respect to the proposition in question. We term this the higher-order evidence account (the HOE account), and present it as a superior to what we might call standard conciliationism, which holds that when agents A and B disagree about p, and are (known) epistemic peers, they should both suspend judgement about p or adjust their confidence towards the mean of A and B’s prior credences in p. Many have suspected that standard conciliationism is implausible and may have skeptical implications. After presenting the HOE account, we put it to work by applying it to a range of cases of moral disagreement, including those that have feature in recent debates assuming standard conciliationism. We show that the HOE account support reasonable, non-skeptical verdicts in a range of cases. Note that this is a paper on moral disagreement, not on the HOE account, thus the account is merely stated here, while defended more fully elsewhere. (shrink)

This paper explores in detail an argument for epistemic expressivism, what we call the Argument from Motivation. While the Argument from Motivation has sometimes been anticipated, it has never been set out in detail. The argument has three premises, roughly, that certain judgments expressed in attributions of knowledge are intrinsically motivating in a distinct way (P1); that motivation for action requires desire-like states or conative attitudes (HTM); and that the semantic content of knowledge attributions cannot be specified without reference to (...) the intrinsically motivating judgments that such attributions express (P2). We argue that these premises entail a version of ecumenical expressivism. Since the argument from motivation has not been explicitly stated before, there is no current discussion of the argument. In this paper we therefore consider and reject various objections that one might propose to the argument, including some that stem from the idea that knowledge is factive, or that knowledge involves evidence that rules out relevant alternatives. Other objections to (P1) specifically might be derived from cases of apparent lack of epistemic motivation considered in in Kvanvig (The value of knowledge and the pursuit of understanding, 2003) and Brown (Nous 42(2):167–189, 2008), as well as from general forms of externalism about epistemic motivation. We consider these and find them wanting. Finally, the paper offers some critical remarks about the prospect of denying (P2). (shrink)

This handbook presents up-to-date theoretical analyses of problems associated with the moral standing of future people in current decision-making. Future people pose an especially hard problem for our current decision-making, since their number and their identities are not fixed but depend on the choices the present generation makes. Do we make the world better by creating more people with good lives? What do we owe future generations in terms of justice? Such questions are not only philosophically difficult and important, but (...) also directly relevant to many practical decisions and policy issues, including on climate, health, population control and taxation. If we are to adequately assess such issues, we must be able to determine the value of differently sized populations. The aim of this handbook is to shed light on the value of population change and the nature of our obligations to future generations, and to offer practical guidance to policy-makers as to how our duties to future generations should be discharged. It contains an extensive and accessible introduction for those unfamiliar with the topic of population ethics as well as original work from key figures in academic debates on population ethics covering three main themes: ways out of the paradoxes of population ethics, questioning some philosophical and methodological assumptions underlying these paradoxes, and several applications of population ethics to real world issues.

We sometimes disagree not only about facts, but also about how best to acquire evidence or justified beliefs within the domain of facts that we disagree about. And sometimes we have no dispute-independent ways of settling what the best ways of acquiring evidence in these domains are. Following Michael Lynch, I call this phenomenon deep disagreement. In the paper, I outline various forms of deep disagreement, following but also in certain respects revising and expanding Lynch’s exposition in (2010, 2012). As (...) is well known, for the externalist about knowledge and epistemic justification deep disagreements may be nothing more than an unfortunate failure of communication. Yet, though he grants this, Lynch argues that deep disagreement points to a sort of practical problem. I agree. In my paper I propose a revised account of the sort of practical problem that deep disagreement may pose. In short, my claim is that deep disagreement may be a problem due to the role that shared factual beliefs may have in common decision-making. I discuss and assess various reactions to the problem of deep disagreement, including the one proposed by Lynch. I argue that none of the solutions discussed in the paper are satisfactory. (shrink)

Design can be thought of as a model for such endeavours as are intended to result in industrially manufactured products by means of thinking and other intellectual activity. Familiarity with the thinking involved in the designing process is important, not only for those engaged in training designers, but for anyone desirous of systemizing the endeavour. One procedure for approaching an understanding of the way designers think is to describe it with the help of different metaphors. There are some metaphors for (...) thinking about complicated and interrelated phenomena that should lend themselves to illustrating the thinking involved in design, albeit with reservations — e.g. the difficulty of allowing due consideration for what is unthinkable and indescribable in this context.

A search is under way for a theory that can accommodate our intuitions in population axiology. The object of this search has proved elusive. This is not surprising since, as we shall see, any welfarist axiology that satisfies three reasonable conditions implies at least one of three counter-intuitive conclusions. I shall start by pointing out the failures in three recent attempts to construct an acceptable population axiology. I shall then present an impossibility theorem and conclude with a short discussion of (...) how it might be extended to pluralist axiologies, that is, axiologies that take more values than welfare into account.

Population axiology concerns how to evaluate populations in terms of their moral goodness, that is, how to order populations by the relations “is better than” and “is as good as”. The task has been to find an adequate theory about the moral value of states of affairs where the number of people, the quality of their lives, and their identities may vary. So far, this field has largely ignored issues about uncertainty and the conditions that have been discussed mostly pertain (...) to the ranking of risk-free outcomes. Most public policy choices, however, are decisions under uncertainty, including policy choices that affect the size of a population. Here, we shall address the question of how to rank population prospects—that is, alternatives that contain uncertainty as to which population they will bring about—by the relations “is better than” and “is as good as”. We start by illustrating how well-known population axiologies can be extended to population prospect axiologies. And we show that new problems arise when extending population axiologies to prospects. In particular, traditional population axiologies lead to prospect-versions of the problems that they praised for avoiding in the risk-free settings. Finally, we identify an intuitive adequacy condition that, we contend, should be satisfied by any population prospect axiology, and show how given this condition, the impossibility theorems in population axiology can be extended to (non-trivial) impossibility theorems for population prospect axiology.

According topositive egalitarianism, not only do relations of inequality have negative value, as negative egalitarians claim, but relations of equality also have positive value. The egalitarian value of a population is a function of both pairwise relations of inequality (negative) and pairwise relations of equality (positive). Positive andnegative egalitarianismdiverge, especially in different-number cases. Hence, an investigation of positive egalitarianism might shed new light on the vexed topic of population ethics and our duties to future generations. We shall here, in light (...) of some recent criticism, further develop the idea of giving positive value to equal relations. (shrink)

We all agree that democratic decision-making requires a factual input, and most of us assume that when the pertinent facts are not in plain view they should be furnished by well-functioning scientific institutions. But how should liberal democracy respond when apparently sincere, rational and well-informed citizens object to coercive legislation because it is based on what they consider a misguided trust in certain parts of science? Cases are familiar, the most prominent concerning climate science and evolution, but one may also (...) count GMO-skepticism and vaccine-skepticism, and there are plenty of others. The paper defends what I, borrowing an expression from Badiola, call Science as Public Reason, asserting roughly that some policy-relevant factual proposition P is part of public reason if and only if there is consensus about P among scientific experts in the relevant well-functioning scientific institutions. I defend this view against the controversiality objection claiming that scientific findings cannot in this general way pass as public reason as they are sometimes controversial among reasonable citizens. My preferred line of defense is what I call Dogmatism about Science as Public Reason, which roughly amounts to insisting on Science as Public Reason on the ground that it is a philosophically well-motivated view, while conceding that it may not be acceptable to all minimally rational and well-informed individuals.

Population axiology concerns how to evaluate populations in regard to their goodness, that is, how to order populations by the relations “is better than” and “is as good as”. This field has been riddled with impossibility results which seem to show that our considered beliefs are inconsistent in cases where the number of people and their welfare varies.1 All of these results have one thing in common, however. They all involve an adequacy condition that rules out Derek Parfit’s Repugnant Conclusion: (...) The Repugnant Conclusion: For any perfectly equal population with very high positive welfare, there is a population with very low positive welfare which is better, other things being equal.2 1 The informal Mere Addition Paradox in Parfit (1984), pp. 419ff is the locus classicus. For an informal proof of a similar result with stronger assumptions, see Ng (1989), p. 240. A formal proof with slightly stronger assumptions than Ng’s can be found in Blackorby and Donaldson (1991). For theorems with much weaker assumptions, see my (1999), (2000b), and especially (2000a), (2001), and (2009). 2 See Parfit (1984), p. 388. My formulation is more general than Parfit’s apart from that he doesn’t demand that the people with very high welfare are equally well off. Expressions such as “a population with very high positive welfare”, “a population with very low positive welfare”, etc., are elliptical for the more cumbersome phrases “a population consisting only of lives with..

In deep disagreements local disagreements are intertwined with more general basic disagreements about the relevant evidence, standards of argument or proper methods of inquiry in that domain. The paper provides a more specific conception of deep disagreement along these lines and argues that while we should generally conciliate in cases of disagreement, this is not so in deep disagreements. The paper offers a general view of disagreement, holding roughly that one should moderate one’s credence towards uncertainty in so far as (...) disagreement with others provides undefeated higher order evidence that one might have made a mistake in one’s appreciation of the first order evidence. When applying this view to deep disagreement we get that in cases of deep disagreement higher order evidence from disagreement is rebutted or undercut by the nature of the disagreement. So, in cases of deep disagreement one should not moderate one’s credence. I finally argue that this gives a better general view of deep disagreement than views appealing to epistemic peers, personal information or independence. (shrink)

Consider a transitive value ordering of outcomes and lotteries on outcomes, which satisfies substitutivity of equivalents and obeys “continuity for easy cases,” i.e., allows compensating risks of small losses by chances of small improvements. Temkin (2001) has argued that such an ordering must also – rather counter-intuitively – allow chances of small improvements to compensate risks of huge losses. In this paper, we show that Temkin's argument is flawed but that a better proof is possible. However, it is more difficult (...) to determine what conclusions should be drawn from this result. Contrary to what Temkin suggests, substitutivity of equivalents is a notoriously controversial principle. But even in the absence of substitutivity, the counter-intuitive conclusion is derivable from a strengthened version of continuity for easy cases. The best move, therefore, might be to question the latter principle, even in its original simple version: as we argue, continuity for easy cases gives rise to a sorites. (shrink)

For the last thirty years or so, there has been a search underway for a theory that can accommodate our intuitions in regard to moral duties to future generations. The object of this search has proved surprisingly elusive. The classical moral theories in the literature all have perplexing implications in this area. Classical Utilitarianism, for instance, implies that it could be better to expand a population even if everyone in the resulting population would be much worse off than in the (...) original. The main problem has been to find an adequate population theory, that is, a theory about the moral value of states of affairs where the number of people, the quality of their lives, and their identities may vary. Since, arguably, any reasonable moral theory has to take these aspects of possible states of affairs into account when determining the normative status of actions, the study of population theory is of general import for moral theory. A number of theories have been proposed in the literature that purport to avoid counterintuitive implications such as the one mentioned above. The suggestions are diverse: introducing novel ways of aggregating welfare into a measure of value, revising the notion of a life worth living, questioning the way we can compare and measure welfare, counting people’s welfare differently depending on the temporal location or the modal features of their lives, and challenging the logic of axiological and normative concepts. We investigate the concepts and assumptions involved in these theories as well as their implications for population theory. In our discussion, we propose a number of intuitively appealing and logically weak adequacy conditions for an acceptable population theory. Finally, we consider whether it is possible to find a theory that satisfies all of these conditions. We prove that no such theory exists. (shrink)

The aim of the paper is to state a version of epistemic expressivism regarding knowledge, and to suggest how this expressivism about knowledge explains the value of knowledge. The paper considers how an account of the value of knowledge based on expressivism about knowledge responds to the Meno Problem, the Swamping Problem, and a variety of other questions that pertains to the value of knowledge, and the role of knowledge in our cognitive ecology.

The person-affecting restriction, in its slogan form, states that an outcome can be better than another only if it is better for someone. It has a strong intuitive appeal and several theorists have suggested that it avoids certain counterintuitive implications in population ethics. At the same time, the restriction has highly counterintuitive implications and yields non-transitive orderings in some nonidentity cases. Many theorists have taken this criticism to be decisive. Recently, however, there have been some reformulations of the restriction, suggesting (...) that the restriction survives this “old” criticism. This paper investigates the viability of those reformulations, which are versions of “Comparativism,” and argues that most of them either have counterintuitive implications or are extensionally equivalent with impersonal theories, but that “Soft Comparativism” seems to have an advantage over impersonal theories.

Suppose that A and B are two kinds of goods such that more of each is better than less. A is strongly superior to B if any amount of A is better than any amount of B. It is weakly superior to B if some amount of A is better than any amount of B. There are many examples of these relations in the literature, sometimes under the labels “higher goods” and “discontinuity.” The chapter gives a precise and generalized statement (...) of Strong and Weak Superiority and discusses different ways in which these relations can be relevant to the aggregation of welfare. It also proves a number of general results. One of the results gives rise to a dilemma: It can be used as an argument against the existence of value superiority or, alternatively, as an argument against the view that superiority entails a radical difference in value.

Can it be better or worse for a person to exist than not to exist at all? This old and challenging existential question has been raised anew in contemporary moral philosophy, mainly for two reasons. First, traditional “impersonal” ethical theories, such as utilitarianism, have counterintuitive implications in population ethics, for example, the repugnant conclusion. Second, it has seemed evident to many that an outcome can be better than another only if it is better for someone, and that only moral theories (...) that are in this sense “person affecting” can be correct. The implications of this Person-Affecting Restriction will differ radically, however, depending on which answer one gives to the existential question. The negative answer, which we argue against, would make the restriction quite untenable. Hence, many of the problems regarding our moral duties to future generations turn around the issue at hand.

Suppose one sets up a sequence of less and less valuable objects such that each object in the sequence is only marginally worse than its immediate predecessor. Could one in this way arrive at something that is dramatically inferior to the point of departure? It has been claimed that if there is a radical value difference between the objects at each end of the sequence, then at some point there must be a corresponding radical difference between the adjacent elements. The (...) underlying picture seems to be that a radical gap cannot be scaled by a series of steps, if none of the steps itself is radical. We show that this picture is incorrect on a stronger interpretation of value superiority, but correct on a weaker one. Thus, the conclusion we reach is that, in some sense at least, abrupt breaks in such decreasing sequences cannot be avoided, but that such unavoidable breaks are less drastic than has been suggested. In an appendix written by John Broome and Wlodek Rabinowicz, the distinction between two kinds of value superiority is extended from objects to their attributes. (shrink)

As the title of this paper indicates, I’m going to discuss what we ought to do in situations where our actions affect future generations. More specifically, I shall focus on the moral problems raised by cases where our actions affect who’s going to live, their number and their well being. I’ll start, however, with population axiology. Most discussion in population ethics has concentrated on how to evaluate populations in regard to their goodness, that is, how to order populations by the (...) relations “is better than” and “is as good as”. This field has been riddled with “paradoxes” which purport to show that our considered beliefs are inconsistent in cases where the number of people and their welfare varies. Derek Parfit’s Mere Addition Paradox is a case in point. The main question of my paper concerns the implication of such axiological paradoxes for normative theories. Do the axiological paradoxes translate into paradoxes for normative theories or will they, as some believe, disappear if we switch to a normative framework? (shrink)

Suppose we have a persistent disagreement about a particular set of policy options, not because of an underlying moral disagreement, or a mere conflict of interest, but rather because we disagree about a crucial non-normative factual assumption underlying the justification of the policy choices. The main question in the paper is what political legitimacy requires in such cases, or indeed whether there are defensible answers to that question. The problem of political legitimacy in fact-dependent policy disagreements has received almost no (...) attention in political philosophy, which has focused mostly on value disagreements and proposed theories of legitimate coercive legislation in valuedependent disagreements. The paper presents an argument showing that under certain plausible assumptions regarding legitimacy, there are serious difficulties in identifying legitimate choices in fact-dependent policy disagreements. This may be unsurprising to political philosophers preoccupied with value-based disagreements, perhaps because it has been assumed that legitimacy-related concerns are irrelevant to fact-dependent policy disagreements. The paper argues that this response is premature. If we should care about legitimacy et al.l, then it is by no means clear why we should ignore issues of legitimacy in policy-disputes that depend on factual disagreements. The paper ends by defining a set of possibilities that merit further exploration in search of a theory of legitimacy in fact-dependent policy disagreements. (shrink)

In an influential article, Simon C. May forcefully argued that, properly understood, there can never be principled reasons for moral compromise. While there may be pragmatic reasons for compromising that involve, for instance, concern for political expediency or for stability, there are properly speaking no principled reasons to compromise. My aim in the article is to show how principled moral compromise in the context of moral disagreements over policy options is possible. I argue that when we disagree, principled reasons favoring (...) compromises or compromising can assume a more significant part of what makes a position all things considered best, and in this way disagreement can ground moral compromise.

The aim of this chapter is to examine how diversity benefits deliberation, information exchange and other socio‐epistemic practices associated with free speech. We separate five distinct dimensions of diversity, and discuss a variety of distinct mechanisms by which various forms of diversity may be thought to have epistemically valuable outcomes. We relate these results to the moral justification of free speech. Finally, we characterise a collective action problem concerning the compliance with truth‐conducive norms of deliberation, and suggest what may solve (...) this problem. (shrink)

In a modern pluralist society, the idea of liberal legitimacy as proposed by John Rawls offers a promising foundation for the further historic advancement of democracy. However, liberal legitimacy still seems to lack one key element—a unique type of respect at its foundations—without which such democratic advancement may not be achieved. Nor, on closer inspection, could the idea of liberal legitimacy succeed without this particular type of respect. When further refined at its foundation, arguably liberal legitimacy could open doors to (...) previously unattainable improvements in democracy and legitimacy. (shrink)
