Algorithm Decision Making (ADM) systems designed to augment or automate human decision-making have the potential to produce better decisions while also freeing up human time and attention for other pursuits. For this potential to be realised, however, algorithmic decisions must be sufficiently aligned with human goals and interests. We take a Principal-Agent (P-A) approach to the questions of ADM alignment and trust. In a broad sense, ADM is beneficial if and only if human principals can trust algorithmic agents to act (...) faithfully on their behalf. This mirrors the challenge of facilitating P-A relationships among humans, but the peculiar nature of human-machine interaction also raises unique issues. The problem of asymmetric information is omnipresent but takes a different form in the context of ADM. Although the decision-making machinery of an algorithmic agent can in principle be laid bare for all to see, the sheer complexity of ADM systems based on deep learning models prevents straightforward monitoring. We draw on literature from economics and political science to argue that the problem of trust in ADM systems should be addressed at the level of institutions. Although the dyadic relationship between human principals and algorithmic agents is our ultimate concern, cooperation at this level must rest against an institutional environment which allows humans to effectively evaluate and choose among algorithmic alternatives.

Aumann’s theorem states that no individual should agree to disagree under a range of assumptions. Political liberalism appears to presuppose these assumptions with the idealized conditions of public reason. We argue Aumann’s theorem demonstrates they nevertheless cannot be simultaneously held with what is arguably political liberalism’s most central tenet. That is, the tenet of reasonable pluralism, which implies we can rationally agree to disagree over conceptions of the good. We finish by elaborating a way of relaxing one of the theorem’s (...) axioms that arguably lends itself to a coherent account of political liberalism, namely the condition of indexical independence.

The problem of the man who met death in Damascus appeared in the infancy of the theory of rational choice known as causal decision theory. A straightforward, unadorned version of causal decision theory is presented here and applied, along with Brian Skyrms’ deliberation dynamics, to Death in Damascus and similar problems. Decision instability is a fascinating topic, but not a source of difficulty for causal decision theory. Andy Egan’s purported counterexample to causal decision theory, Murder Lesion, is considered; a simple (...) response shows how Murder Lesion and similar examples fail to be counterexamples, and clarifies the use of the unadorned theory in problems of decision instability. I compare unadorned causal decision theory to previous treatments by Frank Arntzenius and by Jim Joyce, and recommend a well-founded heuristic that all three accounts can endorse. Whatever course deliberation takes, causal decision theory is consistently a good guide to rational action. (shrink)

If counterfactual dependence is sufficient for causation and if omissions can be causes, then all events have many more causes than common sense tends to recognize. This problem is standardly addressed by appeal to pragmatics. However, Carolina Sartorio [2010] has recently raised what I shall argue is a more interesting problem concerning omissions for counterfactual theories of causation—more interesting because it demands a more subtle pragmatic solution. I discuss the relationship between the idea that causes are proportional to their effects, (...) the idea that causation is contrastive, and the question of the dimensions along which causal explanations should be evaluated with respect to one another.

One guide to an argument's significance is the number and variety of refutations it attracts. By this measure, the Dutch book argument has considerable importance.2 Of course this measure alone is not a sure guide to locating arguments deserving of our attention—if a decisive refutation has really been given, we are better off pursuing other topics. But the presence of many and varied counterarguments at least suggests that either the refutations are controversial, or that their target admits of more than (...) one interpretation, or both. The main point of this paper is to focus on a way of understanding the Dutch Book argument (DBA) that avoids many of the well-known criticisms, and to consider how it fares against an important criticism that still remains: the objection that the DBA presupposes value-independence of bets.

Deep personal relationships involve deep mutual understanding and strong mutual affection. This paper focuses on whether having deep personal relationships is one of the elements of well-being. Roger Crisp put forward thought experiments which might be taken to suggest that having deep personal relationships has only instrumental value as a means to other elements of well-being. The different conclusion this paper draws is that having deep personal relationships is an element of well-being if, but only if, the other people involved (...) have qualities that merit affection for these people.

What can rational deliberation indicate about belief? Belief clearly influences deliberation. The principle that rational belief is stake-invariant rules out at least one way that deliberation might influence belief. The principle is widely, if implicitly, held in work on the epistemology of categorical belief, and it is built into the model of choice-guiding degrees of belief that comes to us from Ramsey and de Finetti. Criticisms of subjective probabilism include challenges to the assumption of additive values (the package principle) employed (...) by defenses of probabilism. But the value-interaction phenomena often cited in such challenges are excluded by stake-invariance. A comparison with treatments of categorical belief suggests that the appeal to stake-invariance is not ad hoc. Whether or not to model belief as stake-invariant is a question not settled here.

This essay contends that the constitutive elements of well-being are plural, partly objective, and separable. The essay argues that these elements are pleasure, friendship, significant achievement, important knowledge, and autonomy, but not either the appreciation of beauty or the living of a morally good life. The essay goes on to attack the view that elements of well-being must be combined in order for well-being to be enhanced. The final section argues against the view that, because anything important to say about (...) well-being could be reduced to assertions about these separable elements, the concept of well-being or personal good is ultimately unimportant.

This paper starts by juxtaposing the normative ethics in the final part of Parfit's final book, On What Matters, vol. 3, with the normative ethics in his earlier books, Reasons and Persons and On What Matters, vol. 1. The paper then addresses three questions. The first is, where does the reflective-equilibrium methodology that Parfit endorsed in the first volume of On What Matters lead? The second is, is the Act-involving Act Consequentialism that Parfit considers in the final volume of On (...) What Matters as plausible as Rossian deontology? The third is, how is the new argument that Parfit puts forward for Rule Consequentialism supposed to work? (shrink)

Dutch Book arguments have been presented for static belief systems and for belief change by conditionalization. An argument is given here that a rule for belief change which under certain conditions violates probability kinematics will leave the agent open to a Dutch Book.

I argue against the claim, advanced by David Albert and Barry Loewer, that all non-fundamental laws can be derived from those required to underwrite the second law of thermodynamics.

This paper looks at the debates between internalism and externalism in mind and epistemology. In each realm, internalists face what we call 'The Connection Problem', while externalists face what we call 'The Problem of Opacity'. We offer an integrated account of thought content and epistemic warrant that overcomes the problems. We then apply the framework to debates between internalists and externalists in metaethics.

I defend an account of explanatory depth according to which explanations in the non-fundamental sciences can be deeper than explanations in fundamental physics.

The non-reductive physicalist would like to believe that mental properties are not identical to physical properties; that there are complete causal explanations of all events in terms of physical properties; and that there are sometimes explanations of events in terms of mental properties. However, some have argued that these claims cannot all be true, since they are collectively inconsistent with a principle of causal exclusion. In this paper I argue that the best formulation of the interventionist theory of causation entails (...) the falsity of the exclusion principle. However, I argue that it does so at the cost of revealing a weakness in the interventionist theory itself. (shrink)

Fixed-rate versions of rule-consequentialism and rule-utilitarianism evaluate rules in terms of the expected net value of one particular level of social acceptance, but one far enough below 100% social acceptance to make salient the complexities created by partial compliance. Variable-rate versions of rule-consequentialism and rule-utilitarianism instead evaluate rules in terms of their expected net value at all different levels of social acceptance. Brad Hooker has advocated a fixed-rate version. Michael Ridge has argued that the variable-rate version is better. The (...) debate continues here. Of particular interest is the difference between the implications of Hooker's and Ridge's rules about doing good for others. (shrink)

Theories of individual well‐being fall into three main categories: hedonism, the desire‐fulfilment theory, and the list theory (which maintains that there are some things that can benefit a person without increasing the person's pleasure or desire‐fulfilment). The paper briefly explains the answers that hedonism and the desire‐fulfilment theory give to the question of whether being virtuous constitutes a benefit to the agent. Most of the paper is about the list theory's answer.

Does the strength of a particular belief depend upon the significance we attach to it? Do we move from one context to another, remaining in the same doxastic state concerning p yet holding a stronger belief that p in one context than in the other? For that to be so, a doxastic state must have a certain sort of context-sensitive complexity. So the question is about the nature of belief states, as we understand them, or as we think a theory (...) should model them. I explore the idea and how it relates to work on imprecise probabilities and second-order confidence. (shrink)

Consider the following causal exclusion principle: For all distinct properties F and F* such that F* supervenes on F, F and F* do not both cause a property G. Peter Menzies and Christian List have proven that it follows from a natural conception of causation as difference-making that this exclusion principle is not generally true. Rather, it turns out that whether the principle is true is a contingent matter. In addition, they have shown that in a wide range of empirically (...) ordinary cases, it follows that F* causes G and F does not. These cases plausibly include instances where F* is a mental property and F and G are physical properties. If this is the right conception of causation, it therefore turns out that the physical world is not causally closed. In this paper I show that there is an alternative conception of causation as difference-making that does not have the same consequences. Whether the physical world is causally closed therefore turns out to depend, inter alia, on which conception of difference-making is correct. I give a number of arguments for the alternative conception of difference-making. (shrink)

I discuss a strategy for grounding ethical naturalism propounded by Frank Jackson and more recently by Allan Gibbard: that the undisputed supervenience of the moral upon the natural (or descriptive) entails that moral properties are natural (or descriptive) properties. I show that this strategy falls foul of certain indubitable constraints governing natural kinds; and I then rebut some objections. The upshot is that no viable strategy for supporting ethical naturalism is to be found along these lines. This result has additional (...) consequences, both for Jackson's attempt to accommodate ethical discourse into the natural world, and for Gibbard's purported 'meta-ethical synthesis'. (shrink)

To what extent do our beliefs, and how strongly we hold them, depend upon how they matter to us, on what we take to be at stake on them? The idea that beliefs are sometimes stake-sensitive (Armendt 2008, 2013) is further explored here, with a focus on whether beliefs may be stake-sensitive and rational. In contexts of extended deliberation about what to do, beliefs and assessments of options interact. In some deliberations, a belief about what you will do may rationally (...) influence your estimate of the value of doing it; deliberation dynamics provides a framework for modeling such interactions. A distinction is drawn between sensitivity to the magnitude of the stakes, and sensitivity to the shape of the stakes. Contexts of extended deliberation are settings in which some beliefs that p rationally depend on the shape of the stakes on p. The dependence is either rational stake-sensitivity or an outcome of rational learning; empirical evidence concerning contexts of deliberation may lead us to model rational beliefs in one way or the other.

The primary aim of this paper is the presentation of a foundation for causal decision theory. This is worth doing because causal decision theory (CDT) is philosophically the most adequate rational decision theory now available. I will not defend that claim here by elaborate comparison of the theory with all its competitors, but by providing the foundation. This puts the theory on an equal footing with competitors for which foundations have already been given. It turns out that it will also (...) produce a reply to the most serious objections made so far against CDT and against the particular version of CDT I will defend. (shrink)

The paper is an examination of Tyler Burge’s notion of epistemic entitlement. It begins with consideration of a recent attempt to understand entitlement, including the ways in which it differs from the more traditional notion of justification. The paper argues that each of Casullo’s central contentions rests upon confusion. More generally, the paper shows that Casullo’s interpretation tries to force Burge’s work into a framework that is not suited for it; and that the interpretation also suffers from not being even (...) minimally informed about the actual character of Burge’s epistemological views. The paper’s second half explains the distinction between entitlement and justification, including ways in which Burge’s understanding of the relevant notions has changed over time. (shrink)

With the publication of A Theory of Justice in 1971, John Rawls not only rejuvenated contemporary political philosophy but also defended a Kantian form of Enlightenment liberalism called “justice as fairness.” Enlightenment liberalism stresses the development and exercise of our capacity for autonomy, while Reformation liberalism emphasizes diversity and the toleration that encourages it. These two strands of liberalism are often mutually supporting, but they conflict in a surprising number of cases, whether over the accommodation of group difference, the design (...) of civic education, or the promotion of liberal values internationally. During the 1980’s, however, Rawls began to jettison key Kantian characteristics of his theory, a process culminating in the 1993 release of Political Liberalism and completing the transformation of justice as fairness into a Reformation liberalism. -/- Reconstructing Rawls argues that this transformation was a tragic mistake because it jeopardized the most important features of his theory, viz. the lexical priorities of right, liberty, and fair equality of opportunity as well as the difference principle. Controversially, this book contends that Rawls’s so-called “political turn,” motivated by a newfound interest in diversity and the accommodation of difference, has been unhealthy for autonomy-based liberalism and has pushed liberalism more broadly towards cultural relativism, be it in the guise of liberal multiculturalism or critiques of cosmopolitan distributive-justice theories. The book then demonstrates that the central elements of justice as fairness can only be defended within the context of a Kantian Enlightenment liberalism and that Rawls’s hope for a more pluralistic grounding for his theory, endorsed by a wide variety of belief systems present in modern democratic societies, is illusory. -/- Reconstructing Rawls is the first book to systematically compare Rawls’s and Kant’s theories and the first to offer an internal critique and reconstruction of justice as fairness, reconceiving it as a comprehensive, universalistic Kantian liberalism. By doing so, it gives us both the vision of a liberal world order—“a republicanism of all states, together and separately,” as Kant put it—and a mode of justification addressed to all men and women, not as members of particular nations, races, and faiths, but as human beings, as citizens of the world. In short, it reclaims Rawls for the Enlightenment. (shrink)

It is widely held that the influence of risk on rational decisions is not entirely explained by the shape of an agent’s utility curve. Buchak (Erkenntnis, 2013, Risk and rationality, Oxford University Press, Oxford, in press) presents an axiomatic decision theory, risk-weighted expected utility theory (REU), in which decision weights are the agent’s subjective probabilities modified by his risk-function r. REU is briefly described, and the global applicability of r is discussed. Rabin’s (Econometrica 68:1281–1292, 2000) calibration theorem strongly suggests that (...) plausible levels of risk aversion cannot be fully explained by concave utility functions; this provides motivation for REU and other theories. But applied to the synchronic preferences of an individual agent, Rabin’s result is not as problematic as it may first appear. Theories that treat outcomes as gains and losses (e.g. prospect theory and cumulative prospect theory) account for risk sensitivity in a way not available to REU. Reference points that mark the difference between gains and losses are subject to framing, many instances of which cannot be regarded as rational. However, rational decision theory may recognize the difference between gains and losses, without endorsing all ways of fixing the point of reference. In any event, REU is a very interesting theory.

Historically, republicans were of different minds about markets: some, such as Rousseau, reviled them, while others, like Adam Smith, praised them. The recent republican resurgence has revived this issue. Classical liberals such as Gerald Gaus contend that neo-republicanism is inherently hostile to markets, while neo-republicans like Richard Dagger and Philip Pettit reject this characterization—though with less enthusiasm than one might expect. I argue here that the right republican attitude toward competitive markets is celebratory rather than acquiescent and that republicanism demands (...) such markets for the same reason it requires the rule of law: because both are essential institutions for protecting individuals from arbitrary interference. I reveal how competition restrains—and in the limit, even eradicates—market power and thereby helps us realize “market freedom,” i.e., freedom as non-domination in the context of economic exchange. Finally, I show that such freedom necessitates “Anglo-Nordic” economic policies. (shrink)

The chapter juxtaposes the fairly quick and automatic thinking and decision making that constitutes everyday moral thought and action with the slower, more complicated, and more reflective thinking that steps beyond everyday moral thought. Various difficulties that can slow down everyday moral thought are catalogued in this paper. The paper explains how dealing with many of these difficulties leads to thinking about moral principles. And, even where there are not such difficulties, everyday moral thought can be challenged by repeated “why?” (...) questions. Pushed far enough, such questions have to be answered by admitting ignorance or by pointing to theses about whatever ultimately makes acts morally required, permissible, or prohibited. Such theses are moral theories. As a point about moral theories, the paper ends by pointing out a respect in which everyday moral thought is more like rule-consequentialism, contractualism, foundational pluralism, and virtue ethics than everyday moral thought is like traditional act-consequentialism.

I argue that considerations pertaining to constitutive luck undermine historicism—the view that an agent’s history can determine whether or not she is morally responsible. The main way that historicists have motivated their view is by appealing to certain cases of manipulation. I argue, however, that since agents can be morally responsible for performing some actions from characters with respect to which they are entirely constitutively lucky, and since there is no relevant difference between these agents and agents who have been (...) manipulated into acting from a character bestowed upon them by their manipulators, we should give up historicism. After presenting this argument and defending it against some potential objections, I briefly criticize the standard structuralist alternative and propose a new structuralist position that is shaped by reflection on constitutive luck.

H.-J. Glock has made important contributions to discussions of rationality, reasons, and rules. This chapter addresses four conceptions of rationality that Glock identifies. One of these conceptions of rationality is that rationality consists in responsiveness to reasons. This chapter goes on to consider the idea that reasons became prominent in normative ethics because of their usefulness in articulating moral pluralism. The final section of the chapter connects reasons and rules and contends that both are ineliminable.

It is unlikely that when my the grandfather of Cometan, Derrick Taylor, sat down to participate in an interview with his good friend Judith Shean now almost thirty years ago that all those years later his grandson would have written a book analysing that very interview. On 22nd February 1995, Derrick Taylor agreed to participate in an interview at his home 222 Longmeanygate to reveal his experience as a Protestant turned Catholic. During the interview, Derrick Taylor provided (...) a realistic view of what his life had been like detailing loss, tragedy and suffering. By contrast, he also detailed his predisposition for experiencing interior locutions – divine communications to the ear – which filled him with great elation in times of spiritual crisis. This interview was titled Light a Candle for Me as based on Derrick Taylor's very first interaction with the Sacred Heart of Jesus when he was just seven years old in which he asked his friend's mother to light a candle for him as a metaphor for his journey to Catholicism. What we ultimately learn of Derrick Taylor's character in this 1995 interview is that he held such a dedication to the Catholic faith that he found it difficult to reconcile the fact that the world and the Church were changing. In this interview, which is now often titled the Sceptre Bulletin Interview, Derrick Taylor tells us in his own words what he thought of the reforms of the Second Vatican Council. This book, the Catholic Conversion, is an exegetical work written by Derrick's grandson Cometan some 27 years later that develops his grandfather's words into a set of theological concepts that come to form Derrick Taylor's definitive approach to Catholicism.

The idea that beliefs may be stake-sensitive is explored. This is the idea that the strength with which a single, persistent belief is held may vary and depend upon what the believer takes to be at stake. The stakes in question are tied to the truth of the belief—not, as in Pascal’s wager and other cases, to the belief’s presence. Categorical beliefs and degrees of belief are considered; both kinds of account typically exclude the idea and treat belief as stake-invariant (...) , though an exception is briefly described. The role of the assumption of stake-invariance in familiar accounts of degrees of belief is also discussed, and morals are drawn concerning finite and countable Dutch book arguments. (shrink)

Intro to festschrift for Jonathan Dancy.

For Aristotle, the shape of a physical body is perceptible per se (DA II.6, 418a8-9). As I read his position, shape is thus a causal power, as a physical body can affect our sense organs simply in virtue of possessing it. But this invites a challenge. If shape is an intrinsically powerful property, and indeed an intrinsically perceptible one, then why are the objects of geometrical reasoning, as such, inert and imperceptible? I here address Aristotle’s answer to that problem, focusing (...) on the version of it that he presents in De caelo III.8. I argue that if we grant that Aristotle conceived of the shape of a sensible body as some kind of causal power, then the satisfactory resolution of that challenge pushes us to interpret him as having conceived of it as being, more specifically, an impure power—that is, as a property that is not only intrinsically powerful but also, in some way, intrinsically non-powerful as well. This is a notable result not only insofar as it illuminates Aristotle’s conception of shape but also insofar as it contributes to our knowledge of Aristotle’s theory of dunameis and his ontology more broadly.

Is the common cause principle merely one of a set of useful heuristics for discovering causal relations, or is it rather a piece of heavy duty metaphysics, capable of grounding the direction of causation itself? Since the principle was introduced in Reichenbach’s groundbreaking work The Direction of Time (1956), there have been a series of attempts to pursue the latter program—to take the probabilistic relationships constitutive of the principle of the common cause and use them to ground the direction of (...) causation. These attempts have not all explicitly appealed to the principle as originally formulated; it has also appeared in the guise of independence conditions, counterfactual overdetermination, and, in the causal modelling literature, as the causal markov condition. In this paper, I identify a set of difficulties for grounding the asymmetry of causation on the principle and its descendents. The first difficulty, concerning what I call the vertical placement of causation, consists of a tension between considerations that drive towards the macroscopic scale, and considerations that drive towards the microscopic scale—the worry is that these considerations cannot both be comfortably accommodated. The second difficulty consists of a novel potential counterexample to the principle based on the familiar Einstein Podolsky Rosen (EPR) correlations in quantum mechanics. (shrink)

On the work of Frank Ramsey, emphasizing topics most relevant to philosophy of science.

Recent develops in AI technology have led to increasingly sophisticated forms of video manipulation. One such form has been the advent of deepfakes. Deepfakes are AI-generated videos that typically depict people doing and saying things they never did. In this paper, I demonstrate that there is a close structural relationship between deepfakes and more traditional fake barn cases in epistemology. Specifically, I argue that deepfakes generate an analogous degree of epistemic risk to that which is found in traditional cases. Given (...) that barn cases have posed a long-standing challenge for virtue-theoretic accounts of knowledge, I consider whether a similar challenge extends to deepfakes. In doing so, I consider how Duncan Pritchard’s recent anti-risk virtue epistemology meets the challenge. While Pritchard’s account avoids problems in traditional barn cases, I claim that it leads to local scepticism about knowledge from online videos in the case of deepfakes. I end by considering how two alternative virtue-theoretic approaches might vindicate our epistemic dependence on videos in an increasingly digital world. (shrink)

Some compatibilists are internalists. On their view, whether an agent is morally responsible for an action depends only on her psychological structure at that time. Other compatibilists are externalists. On their view, an agent’s history can make a difference as to whether or not she is morally responsible. In response to worries about manipulation, some internalists have claimed that compatibilism requires internalism. Recently, Alfred Mele has argued that this internalist response is untenable. The aim of this paper is to vindicate (...) the claim that compatibilism requires internalism, showing where Mele’s argument goes wrong along the way. (shrink)

Derek Parfit’s On What Matters endorses Kantian Contractualism, the normative theory that everyone ought to follow the rules that everyone could rationally will that everyone accept. This paper explores Parfit’s argument that Kantian Contractualism converges with Rule Consequentialism. A pivotal concept in Parfit’s argument is the concept of impartiality, which he seems to equate agent-neutrality. This paper argues that equating impartiality and agent-neutrality is insufficient, since some agent-neutral considerations are silly and some are not impartial. Perhaps more importantly, there is (...) little realistic prospect of Kantian Contractualism converging with Rule Consequentialism unless the same impartial reasons drive rule selection in the two theories.

I examine the epistemic import of collaborative research in science. I develop and defend a functional explanation for its growing importance. Collaborative research is becoming more popular in the natural sciences, and to a lesser degree in the social sciences, because contemporary research in these fields frequently requires access to abundant resources, for which there is great competition. Scientists involved in collaborative research have been very successful in accessing these resources, which has in turn enabled them to realize the epistemic (...) goals of science more effectively than other scientists, thus creating a research environment in which collaboration is now the norm.

A paper of Roger Crisp’s four years ago contained arguments that seemed to imply that having deep personal relationships does not constitute an element of well‐being. The lesson to draw from that paper of Crisp’s, according to a recent journal article of mine, is that one’s having a deep personal relationship does constitute an element of one’s well‐being on condition that one’s affection for the other person is merited. Crisp’s paper earlier in this issue of Ratio responds to my arguments. (...) Here I reply to new questions that Crisp poses or provokes. (shrink)

I argue that any account attempting to do away with resultant or circumstantial moral luck is inconsistent with a natural response to the problem of constitutive moral luck. It is plausible to think that we sometimes contribute to the formation of our characters in such a way as to mitigate our constitutive moral luck at later times. But, as I argue here, whether or not we succeed in bringing about changes to our characters is itself a matter of resultant and (...) circumstantial moral luck. I conclude with a dilemma, both horns of which require accepting some form of moral luck. (shrink)
