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.

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)

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)

This topical collection of Synthese is in honor of Catherine Z. Elgin. The idea for it arose in the context of an international book symposium dedicated to Elgin's latest book, organized by Katherine Dormandy, Christoph Jäger, and myself, which took place at the University of Innsbruck in March 2018. The topical collection comprises fourteen papers addressing a broad array of issues related to True Enough and to Elgin’s work more generally, plus a contribution by Elgin with detailed comments and replies. (...) True Enough is an extraordinarily rich, wide-ranging book; it reflects both the breadth and sharpness of Elgin’s philosophical gaze and exemplifies the impressive variety of her philosophical interests. In this introduction, I give an overview of the topical collection’s content, zooming in on the aspects of Elgin’s work which captured the contributors’ attention. My discussion will not remotely do justice to the complexity of Elgin’s system, but I hope that it will help the reader navigate the topical collection and appreciate how the fourteen papers relate to Elgin’s overall project.

Is art epistemically valuable? Catherine Z. Elgin answers this question in the affirmative. She argues for the epistemic value of art on the basis of her innovative epistemological theory, in which the focus is shifted from knowledge and truth to a non-factive account of understanding. After an exposition and critique of her view, as she develops it in her most recent book “True Enough” (MIT-Press, 2017), I will build on some of her ideas in order to strengthen her account.

_ Purpose. _ The article highlights, on the one hand, the impact of the potential of a developed reflective identity on the processes of civilizational transformations, and on the other hand, the role of the transformational processes of a civilizational scale in the formation of a new type of reflective identity. Acute crisis processes in social development, which humanity has faced so far, in particular after 24.02.2022, indicate the beginning of a radical civilizational transformation. Therefore, in the article, it is (...) necessary to find out with the help of which mental, organizational and personal resources humanity can move to a more developed level of civilization without much loss. It is also necessary to show the importance of the philosophical understanding of reality in the formation of reflective identity because reflection has been the basic method of philosophy since its appearance. _Theoretical basis._ There is an understanding of the inextricable connection between the level of development of civilization and the level of reflective development of the individual fixed in a certain type of identity: a more historically developed stage of civilization corresponds to a more complex type of identity with multi-level reflection. At the same time, achieving a higher level of civilizational development is possible only under the condition of constructing a more complex and multi-level reflexive identity. _Originality._ It consists in establishing that the mental-cognitive mechanisms of reflection during the development of civilization passed through the stages of 1) reflexive forms of "the Axial Age", fixed in the corresponding forms of moral, logical, theological, political, etc. culture since the era of Ancient society; 2) reflexive forms of the Modern era with an emphasis on the inner world of man, the emergence of the reflective division into subject and object of knowledge as an essential feature of epistemology, as well as the formation of a modern type of identity; 3) the dual reflection of the post-industrial society and the Second Modern era, the mechanisms of which contribute to the formation of an active and self-sufficient network society and network crowdfunding economy. In this regard, at various stages of the development of civilization, in accordance with certain reflexive mechanisms, the corresponding types of identity are formed: 1) the basic identity of a person determined by his primary socialization; 2) reflective identity which is associated with the acquired cultural potential of a person and the opportunity to consciously choose special features of one’s own identity, and 3) identity which is associated with the existence in a given social culture of a mechanism of double reflection, which allows not only to make a valuable choice of the trajectory of development own identity but also to construct it. _Conclusions._ The aggravation of the identity problem in the modern world is the result of a civilizational crisis associated with the transformation of modern civilization, the technological basis of which is the introduction of renewable energy and artificial intelligence, as well as the development of network relationships in society. The hierarchical structure of modern identity is conditioned by the gradual historical and civilizational layering of the process of evolution of the reflexive component of identity. In each specific modern society, progressive civilizational transformations take place when an innovative type of identity coexisting with basic and modern types is activated and takes a leadership position. The growing role of network relations in society overcomes the identity crisis due to the reduction of social opposition and the harmonization of different aspects of the identity itself. Perceptible climatic changes and the destruction of the established security system in the world after 24.02.2022 made it obvious to the global thinking public that the world community is at the bifurcation point of a radical civilizational transformation.

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.

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)

Reflective equilibrium is overdue a twenty-first century update. Despite its apparent popularity, there is scant evidence that theorists ever thoroughly implement the method, and fewer still openly and transparently publish their attempts to do so in print—stymying its supposed justificatory value. This paper proposes digitising reflective equilibrium as a solution. Inspired by the global open science movement, it advocates for coupling a novel, digital implementation of the equilibrating process with new publication norms that can capitalise on the inherent reproducibility of (...) digital data. The argument is structured around three main claims: that digitising will make it easier to (a) methodically construct, (b) widely disseminate, and (c) thoroughly critique reflective equilibria. Practical guidance is also provided throughout. Altogether, it is argued that digitisation will not only help theorists to better realise reflective equilibrium’s latent theoretical potential, but also greatly extend its value as a justificatory device in contemporary academic discourses.

The precautionary principle (PP) is an influential principle for making decisions when facing uncertain, but potentially severe, harm. However, there is a persistent disagreement about what the principle entails, exactly. It exists in a multitude of formulations and has potentially conflicting ideas associated with it. Is there even such a thing as ‘the precautionary principle’? This paper analyses the debate between unificationists and pluralists about ‘the PP’, arguing that the debate is hindered by neglecting the question of justification. It introduces (...) reflective equilibrium as a method of justification, and sketches how it could be applied to justify a PP. (shrink)
