Reflective Equilibrium

By late 20th century, the rationality wars had launched debates about the nature and norms of intuitive and reflective thinking. Those debates drew from mid-20th century ideas such as bounded rationality, which challenged more idealized notions of rationality observed since the 19th century. Now that 21st century cognitive scientists are applying the resulting dual process theories to artificial intelligence, it is time to dust off some lessons from this history. So this paper synthesizes old ideas with recent results from experiments (...) on humans and machines. The result is Strategic Reflectivism, which takes the position that one key to intelligent systems (human or artificial) is pragmatic switching between intuitive and reflective inference to optimally fulfill competing goals. Strategic Reflectivism builds on American Pragmatism, transcends superficial indicators of reflective thinking such as model size or chains of thought, and becomes increasingly actionable as we learn more about the value of intuition and reflection.

Are John Rawls’s most noticeable methodological contributions, reflective equilibrium and the original position, consistent with each other? I draw attention to a worry that they stand in inconsistent relationships to the claim that ought implies can: it can only be the case that we ought to do something if we can do it.

In this paper, I present a problem for regarding the reflective equilibrium and original position methods as consistent. I do not prove that there is an inconsistency, but there is a puzzle of how the two methods can be made consistent. The concern about inconsistency is because the former method allows for a kind of historical bias, as noted by T.H. Irwin, whereas the latter method seeks to guard against historical bias.

This paper responds to Thomas Kelly and Sarah McGrath’s worry that there can be evil reflective equilibrium. I propose that some of John Rawls’s restrictions on moral judgments we can enter into the procedure serve to protect against evil reflective equilibrium.

Some of the most influential moral philosophers in the English-speaking world say or suggest that we should only pay attention to moral judgments made in certain states of mind, where these states exclude anxious states. In this paper, I argue that this position faces at least two major problems.

In this paper, I present an objection to the reflective equilibrium method based on land purchases and trespassing. I then propose a solution, which involves a change to how we regard the method.

People make moral judgments in response to actual or hypothetical situations. But should they ignore moral judgments made in some states of mind, such as when they are hesitant, frightened, or under the influence of a drug? John Rawls thinks that moral philosophers should ignore judgments made in such states, but I introduce a proposal according to which, if certain conditions are met, they should not. The proposal is loosely inspired by psychoanalysis.

John Rawls recommends a reflective equilibrium method for evaluating which principles institutions should abide by. In this paper, I identify and challenge three assumptions that he makes.

Does the debate between Rawlsians and liberal perfectionists boil down to the following: for liberal perfectionists, the government should fund aesthetic projects that are in good taste; for Rawlsians, the government should be neutral on the aesthetic value of anything? If so, liberal perfectionists are committed to the view that there is objective aesthetic value. In this paper, I argue that within the Rawlsian system is a thesis that is difficult to reconcile with objectivity about aesthetics.

This is a handout identifying twenty objections that have been made to the reflective equilibrium method.

I consider Timothy Williamson’s objection that we do not have any reason to regard reflective equilibrium as a philosophical method. I present what I think a Rawlsian advocate of the method would say, or could say.

Which moral judgments should one pay attention to in building a moral philosophy? Thomas Kelly and Sarah McGrath object to John Rawls’s suggestion to not rely on judgments heavily bound up with one’s own interests. I propose a solution in response to the objection.

I am not sure who said that liberalism merely alternates between ethics and economics – was it Karl Kraus? – but at first glance the claim is plausible. In this paper I argue that there are varieties of liberalism which do not. Some depend on a nature-culture distinction and some appeal to simplicity in a way that seems aesthetic. In the appendix I introduce a problem for utilitarianism.

T.H. Irwin characterizes the reflective equilibrium procedure as one which should not involve ruthless surgery, in a metaphorical sense. I argue that many people will find avoiding this difficult, because they do not conceive or go in for subtle options.

Timothy Williamson objects that we do not have any reason to regard reflective equilibrium as a philosophical method, whether good or bad. In this paper, I propose a less demanding account of when a method is being described.

This paper argues that evaluation—the operation that takes place within the interval between suspension and commitment—is irreducible to computational selection. To evaluate is to conjecture: to submit a hypothesis to friction with an uncontrolled exteriority, judged by criteria that emerge through the very act of judging. The argument turns on the criterion regress: every computational procedure presupposes a criterion fixed at some level; the indigent agent, lacking a complete behavioral program, halts the regress not by external fiat but by reflective (...) judgment. Three converging lines of evidence—computational, empirical, and philosophical—establish that this difference is structural, not technological. Evaluation is the second of three ontological operations (Suspension → Evaluation → Signature) that constitute free agency and ground legal accountability. (shrink)

Can morality be so demanding that we have reason not to follow its dictates? According to many, it can, if that morality is a consequentialist one. We take the plausibility and coherence of this objection – the Demandingness Objection – as a given and are also not concerned with finding the best response to the Objection. Instead, our main aim is to explicate the intuitive background of the Objection and to see how this background could be investigated. This double aim (...) leads to different albeit connected threads of inquiry. We first outline the Objection, its different forms and how intuition figures in them. After this, we move on to consider the ongoing debate about the use of intuitions in (moral) philosophy with a focus on two challenges: what intuitions are and how we can detect them. To answer these challenges, we propose an account according to which moral intuitions are seemings that are characterized by being non-inferential, spontaneous, non-doxastic, phenomenologically distinctive, non-sensory, intrinsically motivating, and stable. Armed with these seven “markers” of moral intuition, we put a forward a complex experimental methodology and raise and respond to possible problems with it. (shrink)

Under review at Canadian Journal of Philosophy. This paper does five things: (1) It provides an analysis of meta-ethical Non-Realist Cognitivism. (2) It assesses two arguments in favour of the view which have been largely overlooked in analyses so far. (3) It argues that different proponents of the view offer crucially different strategies for vindicating moral objectivity without the metaphysical commitments of traditional non-naturalism. (4) Contrary to other commentators, it argues for the no-truthmaker interpretation of Parfit’s view. (5) It argues (...) that each version of Non-Realist Cognitivism is unlikely to be able to do the explanatory work that seemed to call for an ontologically committal non-naturalism. (shrink)

How can we figure out what’s right or wrong, if moral truths are neither self-evident nor something we can perceive? Very roughly, the method of reflective equilibrium (RE) says that we should begin moral inquiry from what we already confidently think, seeking to find a a match between our initial convictions and general principles that are well-supported by background theories, mutually adjusting both until we reach a coherent outlook in which our beliefs are in harmony (the equilibrium part) and we (...) know why and how they support each other (the reflective part). It has been central to the self-understanding of normative ethics and other branches of philosophy in the last half a century. In this chapter, we examine the history of the idea of RE and introduce a schema for generating 256 variants. We explain why RE is subject to serious objections insofar as it purports to yield epistemic justification in virtue of achieving coherence. However, we also develop a new argument to the effect that RE is the best feasible method for us to achieve moral understanding and the ability to justify our judgments to others. It may thus be crucial for responsible moral inquiry, even if coherence among considered judgments and principles is neither sufficient nor necessary for justified moral belief. (shrink)

Moral collectivists argue that certain groups can bear moral responsibility and moral duties. Moral individualists reject this. In this debate, individualists and collectivists both make a common methodological mistake when theorizing about moral agency, responsibility, and blame. Their arguments implicitly assume an all-out primacy of the individual domain. Unless groups can satisfy the exact conditions of our best theory of individual moral responsibility, they are not morally responsible entities. I argue that none of the plausible arguments justify this all-out primacy. (...) Instead, I defend moderate primacy: (1) We should start our theorizing based on individual cases; and (2) extensional inadequacy for the individual domain is worse than for the group domain. This moderate primacy opens the door for the group domain to play an important role in developing a comprehensive ethical theory. I sketch a directed reflective equilibrium method for systematically including the group domain in our theorizing about moral agency, responsibility, and blame. I further develop the Core Features Argument that shows why the collectivist is justified in developing agent-neutral principles and moral concepts that apply to individual and group agents alike. Finally, I suggest that the group domain offers the potential for adjudicating debates in ethical theory and exciting new lines of inquiry that could help us better understand the moral phenomena that ethical theory seeks to explain.

Reflective equilibrium ("RE", for short) is a method of justification which works roughly as follows: We start with our pre-theoretical judgements (about, e.g. moral issues) and try to explain them by a systematic theory. This leads to a process in which judgements and principles are mutually adjusted to each other until a state of equilibrium is reached. For more than half a century, RE has been very popular, as well as controversial, among philosophers of many persuasions. Given how frequently the (...) method is mentioned, embraced and attacked, it is surprising that only very few attempts have been made at analysing and developing RE in detail. This topical collection brings together papers that develop RE on a conceptual level, analyse it using formal methods or investigate applications of RE. (shrink)

Recent academic discourse about artificial intelligence (AI) has largely been directed at how to best morally program AI or evaluating the ethics of its use in various contexts. While these efforts are undoubtedly important, this essay proposes a complementary objective: deploying AI to enhance our own ethical conduct. One way we might do this is by using AI to deepen our understanding of human moral psychology. In this paper, I demonstrate how advanced machine learning might help us gain clearer insights (...) into “common sense” morality—shared moral convictions that underpin our reflective judgments and inform central aspects of moral philosophy. Pinpointing such convictions has proven challenging amid widespread moral disagreements. Current approaches to understanding these commitments, although exhibiting some key strengths, ultimately struggle to capture relevant features of reflective moral judgments espoused by John Rawls, leaving room for methodological improvement. Modern advances in AI offer a promising opportunity to make progress on this task. This essay envisions the gamified training of a “collective moral conscience model,” able to render judgments about moral situations that align with the deep-seated principles of the human collective. I argue that such an AI model might make progress in overcoming obstacles of disagreement to aid in philosophical theorizing and foster practical applications for the moral life of AI agents and ourselves, such as offering us guidance in time-constrained dilemmas and helping us to reflect on our own biases.

This paper argues that moral philosophers can have a special role in helping members of society come to choose which moral theories to believe. Importantly, the argument does not depend on the idea that moral philosophers (more) reliably have true moral beliefs (or are “Strong Moral Experts”). Instead, the argument is that moral philosophers are well-placed to develop understanding of moral theories by drawing out valid implications (they are “Weak Moral Experts”). By developing valid moral arguments, and by making the (...) relevant implications accessible to society, moral philosophers can help people understand the costs and benefits of various moral theories, allowing them to make more informed choices. This does not imply that everyone will agree; there is room for disagreement about the weight to put on various theoretical costs and benefits. But it does give a metaphilosophical picture of the role of moral philosophers, justify certain kinds of public philosophy, and explain the value that moral philosophers can add to society at the philosophy-public interface.

This article addresses a normative problem for panpsychist views of consciousness. This problem arises when panpsychism is combined with sentientism. According to sentientism, entities endowed with phenomenal consciousness have a special moral status. According to panpsychism, all entities in the universe have phenomenal consciousness in some form. Synthesizing these positions leads to a violation of the normative asymmetry between living and nonliving entities, and potentially leads to a revision of established moral beliefs. The article argues that we have good reasons (...) for both panpsychism and sentientism, and therefore we cannot avoid the normative problem by simply rejecting one of them. We identify four strategies that panpsychists might employ to address the normative challenge they face: narrowing morally relevant phenomenal properties to valence properties, abandoning panpsychism in favor of panprotopsychism, dissociating the phenomenal and normative aspects of experience, and revising our ethics to include new entities. However, none of the strategies provides a definitive solution to the normative problem, because they either have counterintuitive implications or undermine the motivation for developing panpsychist theories of consciousness. We conclude that the normative problem poses a serious obstacle to the justification of panpsychism as a theory of consciousness that satisfies the requirements of reflective equilibrium. (shrink)

How can we study normative questions, the subject matter of normative moral and political philosophy? A common answer is: by relying on our normative intuitions. This paper argues that this method lacks support: we have no good reasons to think we can learn about the normative by relying on our normative intuitions (or ‘considered judgements’). This is argued by examining the six most promising justifications that have been offered for relying on normative intuitions: (1) tracking via a third factor; (2) (...) analogies or companions in guilt; (3) taking intuitions at face value, or phenomenal conservatism; (4) that there are no alternatives; (5) coherentism and reflective equilibrium; and (6) articulation of implicit normative commitments, or mentalism. None of these provide robust support for the practice of relying on normative intuitions. What we should rely on when studying normative questions remains a burning question for anyone who wants to do normative moral or political philosophy. (shrink)

The Golden Rule is regularly used in ordinary life, across many different cultures, to acquire new moral knowledge. At the same time, the Golden Rule is widely ignored both in ethics and metaethics because it seems to be an implausible normative theory. Most philosophers who have paid it any attention have thought that, at best, it is an initially tempting thought whose appeal should be explained by the ultimately correct normative theory. My aim in this paper is to attend to (...) an alternative possibility: the Golden Rule teaches us something about metaethics, in the form of moral epistemology, rather than normative ethics. I will argue that sentimentalism, the view that the emotions are an essential source of moral knowledge, provides a compelling explanation of the usefulness of the Golden Rule. Before giving the sentimentalist explanation, I explain why proposed alternative sources of moral knowledge provide less compelling explanations of its usefulness. (shrink)

If new evidence brings your metaethical view in conflict with a dearly held first order moral belief, what are you to do? Recent arguments in metaethics incorporate opposing claims about the methodological relationship between metaethical theories and our core first order moral beliefs. This paper starts by presenting intuitive arguments for First Order Privilege (FEP), the claim that we epistemically ought to privilege some of our first order views relative to our metaethical views. However, spelling out the details of FEP (...) proves hard. The difficulties emerge if we see what is wrong with an extreme version of FEP, which claims that none of our first order views should be revisable in light of metaethical considerations. Spelling out what is wrong with this view leads us to a general principle of revisability. Yet, this principle has consequences beyond the extreme version of FEP: It shows that even cases where we should not majorly revise our first order view in light of metaethical evidence are not cases of strict unrevisability. In so far as there is first order epistemic privilege, its story is complicated: it will depend on the details of the evidential situation, and it will not consist in certainty in the relevant first order views, nor in a mere difference in our credences in the first order vs. the metaethical.

The goal of this paper is to re-assess reflective equilibrium (“RE”). We ask whether there is a conception of RE that can be defended against the various objections that have been raised against RE in the literature. To answer this question, we provide a systematic overview of the main objections, and for each objection, we investigate why it looks plausible, on what standard or expectation it is based, how it can be answered and which features RE must have to meet (...) the objection. We find that there is a conception of RE that promises to withstand all objections. However, this conception has some features that may be unexpected: it aims at a justification that is tailored to understanding and it is neither tied to intuitions nor does it imply coherentism. We conclude by pointing out a cluster of questions we think RE theorists should pay more attention to. (shrink)

This paper aims to flesh out the celebrated notion of reflective equilibrium within a probabilistic framework for epistemic rationality. On the account developed here, an agent's attitudes are in reflective equilibrium when there is a certain sort of harmony between the agent's credences, on the one hand, and what the agent accepts, on the other hand. Somewhat more precisely, reflective equilibrium is taken to consist in the agent accepting, or being prepared to accept, all and only claims that follow from (...) a maximally comprehensive theory that is more probable than any other such theory. Drawing on previous work, the paper shows that when an agent is in reflective equilibrium in this sense, the set of claims they accept or are prepared to accept is bound to be logically consistent and closed under logical implication. The paper also argues that this account can explain various features of philosophical argumentation in which the notion of reflective equilibrium features centrally, such as the emphasis on evaluating philosophical theories holistically rather than in a piecemeal fashion.

Theories of energy justice are standardly used to evaluate decision-making and policy-design related to energy infrastructure. All too rarely attention is paid to the need for a method of justifying principles of justice as well as justice-based judgments that are appealed to in this context. This article responds to this need by offering an engaged ethics approach to normative justification useful for energy justice theory. More specifically, it presents a method of public reflective equilibrium and shows its potential as systematic (...) method for both anchoring analyses of justice in practically relevant judgments and for critically examining perceived injustices. The method is developed and demonstrated through the case of injustices related to a hypothetical but realistic case of wind power development. Participants were invited to a process of justifying justice-claims, using a version of the method of public reflective equilibrium. They reflected on a preliminary normative framework created by the research team and visually depicted by a graphic artist. The analysis of the workshop identifies the following three themes as particularly important for just wind power development: (1) establishing trust among the stakeholders; (2) questioning energy demand; and (3) identifying the right site and scale for energy decisions. All three themes have to do with fair procedures. The latter part of the paper explores what this means for theorising energy justice and outlines a theory of imperfect procedural energy justice.

The wide reflective equilibrium (WRE) is considered the most important method of ethical justification and is intensively discussed in the scientific community. However, it is unclear to what extent it is actually applied in the ethical literature. The objective of this paper is to fill this gap by providing a critical overview of its explicit applications. Explicit application refers to studies that, following Daniels’ definition, contain three levels, name their elements, and provide a connection between the levels. Philosophers Index, ProQuest, (...) PubMed, Web of Science, and Scopus were searched for studies that explicitly used the WRE method and were written in German or English. All topics, disciplines, and publication forms were considered. Nineteen studies were found in which the WRE was applied 23 times. In the 23 applications, 50 equilibria were discussed, and 19 times it was reported that an equilibrium state was reached. The authors applied the WRE in various disciplines, for different purposes, and to diverse topics. The applications themselves differed considerably regarding the application procedure and the scope. Differences can be seen in particular with regard to the presentation of the adjustment process and the WRE criteria used. The results indicate that the WRE can be successfully applied, but the number of explicit applications is still very low. Further research is needed to develop the WRE into an established method of justification. In particular, standards are needed for adjustment and for WRE criteria. (shrink)

The method of reflective equilibrium (MRE) is a method of justification popularized by John Rawls and further developed by Norman Daniels, Michael DePaul, Folke Tersman, and Catherine Z. Elgin, among others. The basic idea is that epistemic agents have justified beliefs if they have succeeded in forming their beliefs into a harmonious system of beliefs which they reflectively judge to be the most plausible. Despite the common reference to MRE as a method, its mechanisms or rules are typically expressed in (...) a metaphorical or simplified manner and are therefore criticized as too vague. Recent efforts to counter this criticism have been directed towards the attempt to provide formal explications of MRE. This paper aims to supplement these efforts by providing an informal working definition of MRE. This approach challenges the view that MRE can adequately be characterized only in the negative as a set of anti-essentialisms. I argue that epistemic agents follow MRE iff they follow four interconnected rules, which are concerned with a minimalistic form of foundationalism, a minimalistic form of fallibilism, a moderate form of holism, and a minimalistic form of rationality. In the critical spirit of MRE, the corresponding working definition is, of course, provisional and revisable. In general, the aim is to contribute to a reflective equilibrium (RE) concerning MRE. If it is successful, this working definition provides a better grasp of the most basic elements of the method and thereby enhances our understanding of it. (shrink)

The standard interpretation of cognitive reflection tests assumes that correct responses are reflective and lured responses are unreflective. However, prior process-tracing of mathematical reflection tests has cast doubt on this interpretation. In two studies (N = 201), we deployed a validated think-aloud protocol in-person and online to test how this assumption is satisfied by the new, validated, less familiar, and less mathematical verbal Cognitive Reflection Test (vCRT). Importantly, thinking aloud did not disrupt test performance compared to a control group. Moreover, (...) verbalized thoughts in both studies revealed that most (but not all) correct responses involved reflection and that most (but not all) lured responses lacked reflection. These data suggest that the vCRT usually satisfies the standard interpretation of the reflection tests (albeit not without exceptions) and that the vCRT can be a good measure of the construct theorized by the two-factor explication of ‘reflection’ (as deliberate and conscious).

I address the worry that reflective equilibrium is too weak as an account of justification because it fails to let differing views converge. I take up informal aspects of convergence and operationalise them in a formal model of reflective equilibrium. This allows for exploration by the means of computer simulation. Findings show that the formal model does not yield unique outputs, but still boosts agreement. I conclude from this that reflective equilibrium is best seen as a pluralist account of justification (...) that cannot be accused of resulting in an “anything goes” relativism. (shrink)

Cancel culture is a form of societal self-defense that becomes prominent particularly during periods of substantial moral upheaval. It can lead to the polarization of incompatible viewpoints if it is indiscriminately demonized. In this brief editorial letter, I consider framing cancel culture as an essentially contested concept (ECC), according to the theory of Walter B. Gallie, with the aim of establishing a groundwork for a more productive discourse on it. In particular, I propose that intermediate agreements and principles of reasonableness (...) can help refocus the debate on cancel culture towards democratic discourse, without blanket justification for every instance. In this context, asserting that cancel culture is an ECC does not dismiss the potential of achieving consensus on its shared core meaning or societal role. Like other similar ECCs, such as democracy or rule of law, it highlights the importance of contestations in shaping our collective understanding of the concept. (shrink)

Abstract (German version follows): -/- This paper develops a new proposal for a coherentist business ethic in which ethically justified and empirically supported proposed solutions to economic problems are developed through a coherentist process of adjustments between the three levels of (1) conception of problem and its solution, (2) positive economic theory, and (3) ethical theories. Using an example, it illustrates how in this framework, Homann's business ethics gains in validity and relevance but loses its claim to universality. // -/- (...) Diese Arbeit entwickelt eine kohärentistische Wirtschaftsethik, in der ethisch begründete und empirisch gestützte Lösungsvorschläge für ökonomische Probleme durch einen kohärentistischen Anpassungsprozess zwischen den drei Ebenen (1) Auffassung von Problem und Lösungsansatz, (2) positive ökonomische Theorie, sowie (3) ethischen Theorien erarbeitet werden. Anhand eines Beispiels wird illustriert, wie Homanns Wirtschaftsethik in diesem Rahmen an Validität und Relevanz gewinnt, jedoch ihren Universalitätsanspruch verliert. (shrink)

Recent work by Matthew Bedke and Max Hayward develops a new attack on metaethical non-naturalists: that they are committed to an immoral state of mind, because they must be willing to change their mind about the moral importance of certain actions given possible evidence about the layout of the non-natural realm. For example, they must be willing to decrease their credence that torturing babies is bad, if they ever get evidence that torturing babies is not in the extension of a (...) non-natural property. The present paper aims to both develop the strongest version of this argument and propose a response to it. The first section argues that the strongest version of this attack does not depend on whether accepting non-naturalism commits one to believing a certain kind of conditional proposition. Rather, it depends on whether accepting non-naturalism commits one to having a certain kind of conditional credences. Moreover, the moral criticism at hand does not hinge on the causal inertness of non-natural properties. And in so far as the argument does not depend on causal inertness, the people threatened by immorality are not just non-naturalists, but metaethicists in general (Sect. 2). This is because the worry hinges instead on particular relationships of epistemic dependence between our metaethical and some of our ethical views. But it is not clear that those relationships obtain; we could adopt metaethical methodologies that preclude morally problematic dependence of relevant first order views on evidence about our metaethical theories (Sect. 3).

Social scientists, political scientists and philosophers debate key concepts such as democracy, power and autonomy. Contested concepts like these pose questions: Are terms such as “democracy” hopelessly ambiguous? How can two theorists defend alternative accounts of democracy without talking past each other? How can we understand debates in which theorists disagree about what democracy is? This paper first discusses the popular strategy to answer these questions by appealing to Rawls’s distinction between concepts and conceptions. According to this approach, defenders of (...) rival conceptions of, e.g. justice can disagree without talking past each other because they share the concept of justice. It is argued that this idea is attractive but limited in application and that it fails to do justice to the dynamic and normative aspects of concept formation. Reflective equilibrium is then suggested as an alternative approach. It replaces the static contrast between a conceptual ‘core’ and competing conceptions by a dynamic perspective of concept formation as a partly normative undertaking: pre-theoretic language use and commitments can provide a shared starting point for developing alternative accounts which yield different concepts of, e.g. justice. This perspective provides a new understanding of how it is possible that different theorists defend rival accounts of, e.g. justice, without talking past each other. (shrink)

This open access book provides the first explicit case study for an application of the method of reflective equilibrium (RE), using it to develop and defend a precautionary principle. It thereby makes an important and original contribution to questions of philosophical method and methodology. The book shows step-by-step how RE is applied, and develops a methodological framework which will be useful for everyone who wishes to use reflective equilibrium. With respect to precautionary principles, the book demonstrates how a rights-based precautionary (...) principle can be constructed and defended. The case study succeeds in demonstrating that RE can be successfully applied and puts real constraints on the justification process. This is all the more remarkable as the case study was designed as an open-ended process, without presupposing any specific results. This book will be highly relevant both to people interested in philosophical methodology and epistemology, as well as to researchers who are interested in using philosophical methods and tools and applying them to practical problems.

Reflective equilibrium —the idea that we have to justify our judgments and principles through a process of mutual adjustment—is taken to be a central method in philosophy. Nonetheless, conceptions of RE often stay sketchy, and there is a striking lack of explicit and traceable applications of it. This paper presents an explicit case study for the application of an elaborate RE conception. RE is used to reconstruct the arguments from Thomson’s paper “Turning the Trolley” for why a bystander must not (...) divert a runaway trolley from five workmen onto one. Analyzing Thomson’s resulting position with the RE-criteria has two main results: Firstly, the adjustment of one of her commitments can be defended. Secondly, no justified position in RE was reached. With respect to RE as a method, the main results from this application are: There is at least one conception of RE that is sufficiently specified to be applicable; the RE criteria put real constraints on the process of justification; and an explicit application of RE has benefits in terms of clarity while at the same time providing guidance for how the justificatory process could be continued.

In this paper, we focus on one controversial element of the method of reflective equilibrium, namely Rawls’s idea that the commitments that enter the justificatory procedure should be pre-selected or filtered: According to him, only considered judgements should be taken into account in moral philosophy. There are two camps of critics of this filtering process: 1) Critics of reflective equilibrium: They reject the Rawlsian filtering process as too weak and seek a more reliable one, which would actually constitute a distinct (...) epistemic method. 2) Proponents of reflective equilibrium: They reject the Rawlsian filtering process as too exclusionary. We defend RE against its critics, arguing that the method can secure reasonable commitments without depending on a strong external filtering process. However, we side with the critical proponents of reflective equilibrium and argue that without the Rawlsian weak filtering process, RE is more plausible both as a general method as well as in the context of moral philosophy.

The objective of this thesis – Reflective Equilibrium as a Form of Life – is to contribute to the deepening of understanding of the method of reflective equilibrium – a method of internal epistemic justification. In the first part of the study, four paradigmatic conceptions of the method will be analyzed in order to carve out a conceptual core: The ones by John Rawls – who coined the name of the method – Norman Daniels, Michael DePaul and Catherine Elgin. I (...) will argue that the conceptual core of the method contains four elementary rules: 1) A minimalistic fallibilism, 2) a moderate holism, 3) a minimalistic rationality, and 4) a weak foundationalism. Compliance with these rules is necessary and jointly sufficient for any epistemic procedure of justification to be in accordance with the method of reflective equilibrium. The second part of the study is intended to answer some of the open questions concerning this definition of the conceptual core of the method. It will be argued that the a minimalistic fallibilism, as a very central element of the method, is justified since there is no belief whose truth is transparent to an epistemic agent. Even if it were the case that such beliefs exist, there would be attractive options of retreat which provide a quasi-universal justification of minimalistic fallibilism. It will also be argued that all alternative methods of justification are either compatible with the method of reflective equilibrium or are not justified. While a metajustification of the method – understood as a justification of the method employing the method itself – is on the one hand not completely satisfactory, as it presupposes the acceptance of the method before it is justified, it is epistemically acceptable on the other hand, since it allows for a critical inquiry and is open-ended. It will be pointed out that a moderate foundationalism can be justified by the method for some specific area of inquiry insofar as basic beliefs can be identified. Yet, the default-position of the method is only a weak foundationalism (often also termed “coherentism”). With regard to the possibility of a formal interpretation of the method with which one could specify key terms used in the definition of the conceptual core, I will sketch general ways such a formalization might take. However, I will argue that the informal interpretation of the method has priority over any formal interpretation. In the third and concluding part of the study, I will present the claim that one should interpret the method of reflective equilibrium as a form of life. This means that the method is at least implicitly accepted by some epistemic agents: they have developed a disposition and ability to act according to the method. This interpretation of the method can be related to the notion of critical thinking, which, as a civic virtue and educational ideal, is subject of empirical research and practical application. A possible misunderstanding with respect to the method of reflective equilibrium as a form of life should be avoided: To interpret the method as a form of life does not indicate that it must be a comprehensive form of life. Acknowledging it in private life is optional. According to the proposed understanding of the method it is primarily a public and political form of life. (shrink)

Though sometimes maligned, “trolleyology” offers an effective means of opening and framing, not only classes in ethics, but indeed any introductory philosophy course taking a broadly “puzzle-based” approach. When properly sequenced, a subset of the thought experiments that are trolleyology’s stock-in-trade can generate a series of puzzles illustrating the shortcomings of our untutored moral intuitions, and which thus motivate the very enterprise of moral theorizing. Students can be engaged in the attempt to resolve said puzzles, inasmuch as they’re accessible and (...) compelling, and their resolutions generally easy to achieve. Once thus engaged, students can be directed to the fact that they had already rolled up their sleeves and begun “doing philosophy.” In this way, engagement with trolleyological puzzles can serve as a “microcosm” for philosophy more broadly, illustrating the processes of critical thinking that are likewise the stock-in-trade of philosophers across many different domains of inquiry.

Reflective equilibrium (RE) is often regarded as a powerful method in ethics, logic, and even philosophy in general. Despite this popularity, characterizations of the method have been fairly vague and unspecific so far. It thus may be doubted whether RE is more than a jumble of appealing but ultimately sketchy ideas that cannot be spelled out consistently. In this paper, we dispel such doubts by devising a formal model of RE. The model contains as components the agent’s commitments and a (...) theory that tries to systematize the commitments. It yields a precise picture of how the commitments and the theory are adjusted to each other. The model differentiates between equilibrium as a target state and the dynamic equilibration process. First solutions to the model, obtained by computer simulation, show that the method allows for consistent specification and that the model’s implications are plausible in view of expectations on RE. In particular, the mutual adjustment of commitments and theory can improve one’s commitments, as proponents of RE have suggested. We argue that our model is fruitful not only because it points to issues that need to be dealt with for a better understanding of RE, but also because it provides the means to address these issues.

In this paper, we argue that solutions to normative challenges associated with autonomous driving, such as real-world trolley cases or distributions of risk in mundane driving situations, face the problem of reasonable pluralism: Reasonable pluralism refers to the fact that there exists a plurality of reasonable yet incompatible comprehensive moral doctrines within liberal democracies. The corresponding problem is that a politically acceptable solution cannot refer to only one of these comprehensive doctrines. Yet a politically adequate solution to the normative challenges (...) of autonomous driving need not come at the expense of an ethical solution, if it is based on moral beliefs that are (1) shared in an overlapping consensus and (2) systematized through public reason. Therefore, we argue that a Rawlsian justificatory framework is able to adequately address the normative challenges of autonomous driving and elaborate on how such a framework might be employed for this purpose.

Reflectivists consider reflective reasoning crucial for good judgment and action. Anti-reflectivists deny that reflection delivers what reflectivists seek. Alas, the evidence is mixed. So, does reflection confer normative value or not? This paper argues for a middle way: reflection can confer normative value, but its ability to do this is bound by such factors as what we might call epistemic identity: an identity that involves particular beliefs—for example, religious and political identities. We may reflectively defend our identities’ beliefs rather than (...) reflect open-mindedly to adopt whatever beliefs cohere with the best arguments and evidence. This bounded reflectivism is explicated with an algorithmic model of reflection synthesized from philosophy and science that yields testable predictions, psychometric implications, and realistic metaphilosophical suggestions—for example, overcoming motivated reflection may require embracing epistemic identity rather than veiling it (à la Rawls 1971). So bounded reflectivism should be preferred to views offering anything less. (shrink)

This article brings together two different topics: reflective equilibrium (RE) and belief revision theory (BRT). RE is a popular method of justification in many areas of philosophy, it involves a process of mutual adjustments striving for a state of coherence, but it lacks formally rigorous elaborations and faces severe criticism. To elucidate core elements of RE and provide a solid basis to address objections, a formal model of RE within BRT is presented. A fruitful starting point to the formalization of (...) RE is Olsson’s coherentist interpretation of semi-revision, but it does not come with a comparative notion of stability. This paper develops an account of comparative stability in an RE setting for belief changing operations. The operations are useful to characterize RE states as well as processes, and they are shown to satisfy postulates of rational belief change. (shrink)

In this paper, I attempt to synthesize the two most influential contemporary ethical approaches that appeal to moral intuitions, viz., Rawlsian reflective equilibrium and Audi’s moderate intuitionism. This paper has two parts. First, building upon the work of Audi and Gaut, I provide a more detailed and nuanced account of how these two approaches are compatible. Second, I show how this novel synthesis can both (1) fully address the main objections to reflective equilibrium, viz., that it provides neither necessary nor (...) sufficient conditions for the justification of our moral beliefs and (2) help ethical intuitionism to deal with the fundamental problem of peer disagreement over our basic moral intuitions. In doing so, I sketch out a novel and attractive diachronic way of thinking about peer disagreement more generally. (shrink)

I argue against the claim that it is trivial to state that Sidgwick used the method of wide reflective equilibrium. This claim is based on what could be called the Triviality Charge, which is pressed against the method of wide reflective equilibrium by Peter Singer. According to this charge, there is no alternative to using the method if it is interpreted as involving all relevant philosophical background arguments. The main argument against the Triviality Charge is that although the method of (...) wide reflective equilibrium is compatible with coherentism (understood as a form of weak foundationalism) as well as moderate foundationalism, it is not compatible with strong foundationalism. Hence, the claim that a philosopher uses the method of wide reflective equilibrium is informative. In particular, this is true with regard to Sidgwick. (shrink)
