The anthropological approach is the central focus of this study. Laboratories are looked upon with the innocent eye of the traveller in exotic lands, and the societies found in these places are observed with the objective yet compassionate eye of the visitor from a quite other cultural milieu. There are many surprises that await us if we enter a laboratory in this frame of mind... This study is a realistic enterprise, an attempt to truly represent the social order of life (...) in laboratories and institutes of research, just as they are. By bringing the philosophical issues to the surface as matters not of prejudgement but as matters of concern, Karin Knorr-Cetina has developed the first really positive challenge to the philosophy of science since the days of paradigms and internal definitions of meanings.

Chapter Growing up Constructivist: Languages and Thoughtful People What is radical constructivism? It is an unconventional approach to the problems of ...

Constructivism is one of the most influential theories in contemporary education and learning theory. It has had great influence in science education. The papers in this collection represent, arguably, the most sustained examination of the theoretical and philosophical foundations of constructivism yet published. Topics covered include: orthodox epistemology and the philosophical traditions of constructivism; the relationship of epistemology to learning theory; the connection between philosophy and pedagogy in constructivist practice; the difference between radical and social constructivism, (...) and an appraisal of their epistemology; the strengths and weaknesses of the Strong Programme in the sociology of science and implications for science education. The book contains an extensive bibliography. Contributors include philosophers of science, philosophers of education, science educators, and cognitive scientists. The book is noteworthy for bringing this diverse range of disciplines together in the examination of a central educational topic. (shrink)

Constructivism in ethics is the view that insofar as there are normative truths, for example, truths about what we ought to do, they are in some sense determined by an idealized process of rational deliberation, choice, or agreement. As a “first-order moral account”--an account of which moral principles are correct-- constructivism is the view that the moral principles we ought to accept or follow are the ones that agents would agree to or endorse were they to engage in (...) a hypothetical or idealized process of rational deliberation. As a “metaethical account” – an account of whether there are any normative truths and, if so, what they are like – constructivism holds that there are normative truths. These truths are not fixed by facts that are independent of the practical standpoint, however characterized; rather, they are constituted by what agents would agree to under some specified conditions of choice. In working to provide a more precise definition of constructivism in metaethics, the focus of this entry, one faces two main difficulties. The first difficulty is that constructivism comes in several varieties, each of which claims a different niche within metaethics, and some claim no space at all. The second difficulty concerns where to place constructivism on the metaethical map in relation to realism and anti-realism. These are terms of art, and it is highly contested which views count as realist and which as antirealist. These two difficulties will be addressed in what follows by focusing on the distinctive questions that constructivist theories are designed to answer. Section §1 defines the scope of constructivism in ethics, in contrast to constructivism in political theory. Sections §§2-5 illustrate the main varieties of metaethical constructivism, which are designed to account for the nature of normative truths and practical reasons. Section §6 presents the main varieties of constructivist accounts of the justification of moral judgments of right and wrong. Section §7 discusses the metaethical status of constructivism, and its distinctive import. (shrink)

Motivation: Paralleling my own transformation from a Platonist to a radical constructivist, mathematics education has been experiencing for more than a decade a movement that started in theoretical foundations mostly originating in von Glasersfeld's work, and then reached professional organizations, which have been leading extensive efforts to reform school mathematics according to constructivist principles. However, the theories espoused by the researchers are, as yet, too abstract to lend themselves readily to implementation in the classroom. N2 - Purpose: I define a (...) shared experiential language (SEL) for the constructivist teacher to embody in order to transform her practice congruently according to constructivist principles. While SEL is comprised of Neuro-Linguistic Programming (NLP) subjective experience distinctions, what "makes it tick" is the constructivist epistemology with its insight that for consistent understanding to happen, new knowledge has to attach to prior experiences in a process of co-construction. Throughout the paper, I elaborate and validate this insight by numerous examples. Practical implications: Utilizing SEL allows understanding of mathematics to be rooted in each student's individual sensory experiences, thus shifting the responsibility for success in mathematics from the students back to those who guide them in co-constructing knowledge. This, in turn, should allow everybody access to understanding and so it should no longer be socially acceptable to fail in mathematics. (shrink)

Ethical constructivism holds that truths about the relation between rationality, morality, and agency are best understood as constructed by correct reasoning, rather than discovered or invented. Unlike other metaphors used in metaethics, construction brings to light the generative and dynamic dimension of practical reason. On the resultant picture, practical reasoning is not only productive but also self-transforming, and socially empowering. The main task of this volume is to illustrate how constructivism has substantially modified and expanded the agenda of (...) metaethics by refocusing on rational agency and its constitutive principles. In particular, this volume identifies, compares and discusses the prospects and failures of the main strands of constructivism regarding the powers of reason in responding to the challenges of contingency. While Kantian, Humean, Aristotelian, and Hegelian theories sharply differ in their constructivist strategies, they provide compelling accounts of the rational articulation required for an inclusive and unified ethical community.

Constructivism about practical judgments, as I understand it, is the notion that our true normative judgments represent a normative reality, while denying that that reality is independent of our exer-cise of moral and practical judgment. The Kantian strain of practical constructivism (through Kant himself, John Rawls, Christine Korsgaard, and others) has been so influential that it is tempting to identify the constructivist approach in practical domains with the Kantian development of the out-look. In this essay I explore a (...) somewhat different variety of practical constructivism, which I call Aristotelian Constructivism. My aim is to establish conceptual space for this form of constructivism by indicating both in what ways it agrees with its Kantian counterparts and in what ways it differs. I argue that Aristotelian Constructivism is on one sense more faithful to the constructivist enterprise than the Kantian varieties, in that its understanding of both the establishment of practical truth and the vindication of the theory itself is constructivist.

This chapter presents an argument about constructivism, schooling and reason. A central argument of the chapter is that the representationalist paradigm referred to by Brandom underpins much of the discussion of Vygotsky, with consequences for the way in which sociogenesis is theorised. It plays a decisive if undeclared role in the conceptualisation of pedagogy in contemporary schooling and has decisive consequences for the way that constructivist positions are taken in relation to the active participation of learners, both in their (...) learning and also more radically in the constitution of knowledge. This is considered in the latter part of the chapter. The chapter talks about Robert Brandom whose work is especially relevant to the distinction between causes and reasons. Constructivism is influential in the appropriation of Vygotsky, yet at the same time a tension arises as a result of the importance Vygotsky attached to instruction. (shrink)

Cosmopolitan critics attack the scope-limitation of justice of egalitarian liberal theorists to states. They treat justice as the production of a given set of outcomes for people regardless of location or relationship. However, in doing so they either ignore the relevant agent towards whom principles of justice are addressed or see the question of agency as a practical, derivative question, of a secondary character. This paper argues that a principle of justice without a clearly justified agent is not a genuine (...) principle at all. This is what writers like Rawls mean by the "subject" of justice (analogous to the grammatical subject of a sentence, i.e.,the agent). We should reflect on agents and why they would or would not justifiably carry certain burdens for others and what kind of benefits or goods they are able to secure. The answers to those questions explain why the idea of cosmopolitan global justice is incomplete, either requiring a global basic structural agency or not applying because no relevant agent is present that can create cooperative arrangements between individual persons across the globe. Other moral principles will still apply globally, but they will be distinct from those that apply to basic-structural agencies. This account is not a practice dependence account, as it bases the distinctness of moral and political principles on purely moral and value-based considerations. (shrink)

Extends the ideas of social constructivism to the philosophy of mathematics, developing a powerful critique of traditional absolutist conceptions of mathematics, and proposing a reconceptualization of the philosophy of mathematics.

Social constructionists maintain that we invent the properties of the world rather than discover them. Is reality constructed by our own activity? Do we collectively invent the world rather than discover it? André Kukla presents a comprehensive discussion of the philosophical issues that arise out of this debate, analysing the various strengths and weaknesses of a range of constructivist arguments and arguing that current philosophical objections to constructivism are inconclusive. However, Kukla offers and develops new objections to constructivism, (...) distinguishing between the social causes of scientific beliefs and the view that all ascertainable facts are constructed.

It is largely agreed that if constructivism contributes anything to meta-ethics it is by proposing that we understand ethical objectivity “in terms of a suitably constructed point of view that all can accept” (Rawls 1980/1999: 307). Constructivists defend this “practical” conception of objectivity in contrast to the realist or “ontological” conception of objectivity, understood as an accurate representation of an independent metaphysical order. Because of their objectivist but not realist commitments, Kantian constructivists place their theory “somewhere in the space (...) between realist and relativist accounts of ethics” (O’Neill 1988: 1). Furthermore, they argue that their practical conception of objectivity succeeds in making sense of certain features of morality, such as its categorical authority and its relation to rational agency, which escape rival theories (Korsgaard 1996b, Korsgaard 2003b). To this extent, constructivism claims a privileged place in meta-ethics. The legitimacy of this claim is widely challenged. Precisely because of its practical conception of objectivity, many – including some constructivists — regard constructivism as a first-order normative theory, rather than as a meta-ethical position, hence not on a par with realism. Some critics object that constructivism fails to offer a distinct meta-ethics because it is structurally incomplete and thus must be combined with a fully-fledged meta-ethics (Hussain and Shah 2006); others argue that it tacitly relies on realism (Timmons 2003; Shafer-Landau 2003; Larmore 2008). Thus far, the debate about the prospects of constructivism as a meta-ethical theory has been driven by the conviction that the case for or against constructivism depends on its ontological commitments. In this chapter, I propose a change in perspective. My aim is to defend constructivism as an objectivist account of practical knowledge. Its defining feature is the claim that practical knowledge is knowledge by principles. Its task is to establish a constitutive relation between knowledge of oneself as a practical subject and knowledge about what one ought to do. By focusing on the issue of practical knowledge I hope to show that the difficulty in situating Kantian constructivism firmly on the meta-ethical map, along with other meta-ethical theories, reflects ambiguities and oscillations about the practical significance of ethics. Even though the term is ambiguous, I retain the qualification “Kantian” for the constructivist theory I outline, and for two reasons. First, while the theory I outline differs from current agnostic or anti-realist variants, it is closer to its origins, since Kant treats practical reason as a cognitive capacity and takes moral judgments to be objective moral cognitions, which importantly differ from other sorts of rational cognitions because they bind us in the first person. Practical cognitions are common knowledge because they are such that all subjects endowed with rationality can arrive at them by reasoning and find them authoritative. Thus understood, Kantian constructivism carves a distinct logical space in the meta-ethical debate that other sorts of constructivism fail to identify. This is the second reason for keeping the qualification “Kantian”. On this formulation, constructivism is antagonistic to non-cognitivist theories denying that moral judgments have cognitive contents, because they deny that there is something to be known; but it is also a rival to cognitivist theories denying that knowledge can be practical in itself. How constructivism differs over the realist theories of practical reason is the least understood aspect of this debate. This essay aims to make the case that practical reason is both discursive and emotional. In contrast to foundational and anti-realist accounts of practical reasoning, it attempts to show that the moral feeling of respect plays a cognitive but non-evidential role in the account of the cognitive and practical powers of reason. The argument proceeds as follows. In section 1, I consider some prominent constructivist arguments against the model of applied knowledge and show that they are driven by non-cognitivist assumptions about the practicality of ethics and the legitimacy of epistemological claims. In section 2, I argue that these arguments do not succeed in disposing of the idea of practical knowledge as incoherent, because they trade on an ambiguity regarding the proper object of practical knowledge. To solve this ambiguity, I turn to Anscombe’s contrast between “practical” and “speculative” knowledge as models for understanding action. I thus suggest that Anscombe’s account of practical knowledge as knowledge of oneself as an agent is an important resource for Kantian constructivism. This finding prompts us to reset the current dispute about the ontological and epistemological commitments of Kantian constructivism, as illustrated in section 3. While constructivism does not postulate any moral ontology prior to reasoning, it attributes to reasoning the cognitive powers to establish a distinctive relation between the agent and her action. The task of sections 4-7 is to account for the distinctive features of Kantian constructivism understood as an objectivist account of practical knowledge. In section 4, I argue that in order for reasoning to accomplish its normative tasks, it should be conceived as a self-legislating activity. I respond to some objections to the idea of self-legislation as the form of rational willing by offering a dialogical view of practical reason. In section 5, I propose a non-standard interpretation of Kant’s argument of “the fact of reason” to show that the constructivist account of self-legislation does not build on realism about value, as its detractors claim. The “basis of construction” is the subjective experience of respect for the self-legislative capacity itself. This moral feeling conveys our awareness of rational agency and shows our responsiveness to the demands of practical reason. It is an emotional mode of practical knowledge of oneself as an agent (in the sense specified in section 2), but not as a mode of moral discernment. In section 6, I show how practical knowledge of oneself as an agent relates to practical knowledge about what one ought to do. I thus account for the relation between respect as emotional moral consciousness and respect as a deliberative constraint. Finally, in section 7, I reply to the objection of subjectivism. I explain how the complex sort of objectivity that Kantian constructivism affords is at the same time more ambitious and more modest than is generally assumed. (shrink)

Constructivists hold that truths about practical reasons are to be explained in terms of truths about the correct exercise of practical reason (rather than vice versa). But what is the normative status of the correctness-defining standards of practical reason? The problem is that constructivism appears to presuppose the truth of two theses that seem hard to reconcile. First, for constructivism to be remotely plausible, the relevant standards must be genuinely (and not merely formally or minimally) normative. Second, to (...) avoid circularity, the relevant standards must be non-reason-involving, i.e. prior to and independent of practical reasons. From the standpoint of the contemporary philosophy of normatively, this is a surprising combination to say the least. What could these genuinely normative but non-reason-involving standards possibly be? The standard constructivist response is to insist that the relevant standards possess a special kind of necessity inasmuch as we only count as occupying the “deliberative standpoint” or as a “deliberative agent” insofar as we comply with or accept the relevant standards. I offer a different response. My response holds that the special normative status of the relevant standards consists in their exhibiting a distinctive kind of practical necessity that derives from the fact that they determine what I have called elsewhere truths about “the thing to do” – namely, truths about correct answers to the question of what to do. Understanding the norms of practical reason in these terms vindicates the idea that standards of practical reason are genuinely normative since truths about the thing to do plausibly possess the hallmarks of genuine normativity. And it vindicates the idea that the standards are not reason-involving since truths about the thing to do are plausibly prior to and independent of truths about practical reasons. (shrink)

Given constructivism’s enduring popularity and appeal, it is perhaps something of a surprise that there remains considerable uncertainty among many philosophers about what constructivism is even supposed to be. My aim in this article is to make some progress on the question of how constructivism should be understood. I begin by saying something about what kind of theory constructivism is supposed to be. Next, I consider and reject both the standard proceduralist characterization of constructivism and (...) also Sharon Street’s ingenious standpoint characterization. I then suggest an alternative characterization according to which what is central is the role played by certain standards of correct reasoning. I conclude by saying something about the implications of this account for evaluating the success of constructivism. I suggest that certain challenges that have been raised against constructivist theories are based on dubious understandings of constructivism, whereas other challenges only properly come into focus once a proper understanding is achieved.

Context: To speak of constructivism -- and in particular of radical constructivism -- in education is to place oneself on a field which, like any other academic field, is the scene of tensions, debates, and indeed battles. While such controversies are, predictably enough, fought out between the partisans of constructivism and those defending other theses, they are also fought out between the constructivists themselves, as a number of group works have brought out (e.g., Steffe & Gale 1995; (...) SRED 2001). In other words, constructivists do not express their views in unison whenever there is a question on the development of knowledge (an individual or collective matter?), the underpinnings of knowledge (be they of a psychological, sociological or other type) or, as humorously noted by Quale (2007), that "sin" which is said to consist in the relativist mode of questioning or critique authorized by constructivism. Purpose: In this paper, we would like to contribute to this discussion and to this plurality of ways of embedding oneself in constructivism, in particular by bringing out (as was so acutely shown by Ernst von Glasersfeld 1987a, 1995, 2007) that while constructivism offers a basis on which to revisit the question of knowledge, its contributions nevertheless extend well beyond this single preoccupation. By reincorporating "the properties of the observer" into his or her discourse as well as the conditions, stakes and issues surrounding the utterance in question, in short, by reincorporating the question of power into the utterance-making, constructivism also provides a basis for revisiting the "Great Divides" -- that is, the (unequal) relationships between the various forms of knowledge as well as the (unequal) modes of evidence and authority that accompany these relations. Method: Through an examination of three topics, that is the "racism" of intelligence, the Semmelweis affair, and the question of endogenous knowledge, we will attempt to explicate various insights afforded by constructivism. Conclusion: So doing, we will show that radical constructivism, in its recognition of the plurality of possible modes of description and explanation, contributes to a form of epistemological democracy.

Are there such things as moral truths? How do we know what we should do? And does it matter? Constructivism states that moral truths are neither invented nor discovered, but rather are constructed by rational agents in order to solve practical problems. While constructivism has become the focus of many philosophical debates in normative ethics, meta-ethics and action theory, its importance is still to be fully appreciated. These new essays written by leading scholars define and assess this new (...) approach in ethics, addressing such questions as the nature of constructivism, how constructivism improves our understanding of moral obligations, how it accounts for the development of normative practices, whether moral truths change over time, and many other topics. The volume will be valuable for advanced students and scholars of ethics and all who are interested in questions about the foundation of morality. (shrink)

Political constructivism is associated with John Rawls more than any other contemporary philosopher. This chapter suggests that Rawls's political constructivism is better understood as a general method of justification which runs throughout his work as a whole, including his early work and A Theory of Justice. The chapter develops the general characterization of Rawls's political constructivism. Its main elements are taken in turn and developed with special attention to the two places where Rawls discusses the topic in (...) depth – his Dewey Lectures on Kantian Constructivism in Moral Theory and its substantially revised version called “Political Constructivism” (PL, Lecture III). The main elements include social role, sources, interpretive basis, representation and conclusion. Rawls endorsed a Kantian metaethical constructivism in part because it offered a way of more deeply characterizing how his previous political constructivism could be a live and distinct possibility.

A new form of skepticism is described, which holds that objectivity and understanding are incompossible ideals of modern science. This is attributed to Weyl, hence its name: Weylean skepticism. Two general defeat strategies are then proposed, one of which is rejected.

A recurrent challenge in applied ethics concerns the development of principles that are both suitably general to cover various cases and sufficiently exact to guide behavior in particular instances. In business ethics, two central approaches—stockholder and stakeholder—often fail by one or the other requirement. The author argues that the failure is precipitated by their reliance upon “universal” theory, which views the justification of principles as both independent of their context of application and universally appropriate to all contexts. The author develops (...) a contextual interpretation of “constructivism” as an alternative approach, and argues that this alternative meets the above challenge. (shrink)

In this paper epistemological, ontological and sociological questions concerning the statistical significance of sharp hypotheses in scientific research are investigated within the framework provided by Cognitive Constructivism and the FBST (Full Bayesian Significance Test). The constructivist framework is contrasted with the traditional epistemological settings for orthodox Bayesian and frequentist statistics provided by Decision Theory and Falsificationism.

Psychological essentialism is a cognitive bias through which human beings conceive the entities around them as having inner essences and basic natures. Social scientists routinely generate flawed inferences because their methods require the truth of psychological essentialism. This article develops set-theoretic analysis as a scientific-constructivist approach that overcomes the bias of psychological essentialism. With this approach, the “sets” of set-theoretic analysis are mental phenomena that establish boundaries and identify similarities and differences among entities whose natural kind composition is not known. (...) The approach is illustrated through a consideration of research on intelligence, race, and poverty in the United States. (shrink)

The present volume is intended as an all-round introduction to constructivism. Here constructivism is to be understood in the wide sense, and covers in particular Brouwer's intuitionism, Bishop's constructivism and A.A. Markov's constructive recursive mathematics. The ending "-ism" has ideological overtones: "constructive mathematics is the (only) right mathematics"; we hasten, however, to declare that we do not subscribe to this ideology, and that we do not intend to present our material on such a basis.

According to the standard objection, Kantian constructivism implicitly commits to value realism or fails to warrant objective validity of normative propositions. This paper argues that this objection gains some force from the special case of moral obligations. The case largely rests on the assumption that the moral domain is an eminent domain of special objects. But for constructivism there is no moral domain of objects prior to and independently of reasoning. The argument attempts to make some progress in (...) the debate by defending a robust conception of construction, which names a distinctive view of practical reasoning as transformative. (shrink)

Recent defenders of metaethical constructivism (like Christine Korsgaard, Sharon Street, Aaron James, and Carla Bagnoli) argue that this view can be shown to represent a new, free-standing alternative to familiar approaches in metaethics. If they are correct, traditional discussions in metaethics have overlooked an important position, one that is supposed to adequately explain the nature of our ethical thinking and practice while avoiding the kinds of objections that traditional views struggle with. However, what form constructivism should take and (...) whether constructivists can make good on this ambitious claim remains extremely controversial. This article starts out with a brief account of the origins of contemporary discussions of constructivism. It then moves on to canvass the main motivations and arguments for constructivism along with the various ways in which the view has been interpreted. In the second half of the article, it introduces a serious challenge to the ambitious claim that constructivism represents a new, free-standing approach in metaethics and concludes by entertaining a very recent proposal that this challenge might overlook.

In this paper I introduce a version of constructivism that relies on a theory of practical wisdom. Wise judgment constructivism is a type of constructivism because it takes correct judgments about what we have “all-in” reason to do to be the result of a process we can follow, where our interest in the results of this process stems from our practical concerns. To fully defend the theory would require a comprehensive account of wisdom, which is not available. (...) Instead, I describe a constructivist methodology for defending an account of wisdom and outline its main features. This gives us enough to see what wise judgment constructivism would look like, why it might be an attractive theory, and how it is different from other versions of constructivism. (shrink)

Context: Cognitive science, as an interdisciplinary research endeavour, poses challenges for teaching and learning insofar as the integration of various participating disciplines requires a reflective approach, considering and making explicit different epistemological attitudes and hidden assumptions and premises. Only few curricula in cognitive science face this integrative challenge. Problem: The lack of integrative activities might result from different challenges for people involved in truly interdisciplinary efforts, such as discussing issues on a conceptual level, negotiating colliding frameworks or sets of premises, (...) asking profound questions challenging one’s own paradigm, and differences in terminologies, as well as from the “personal” challenge of realising one’s own limits of knowledge and, hence, the need to trust in another person’s expertise. This implies that the proposed curriculum structure provides an “epistemic laboratory”: a space for experiencing and negotiating, as well as constructing different viewpoints in a trustful setting. Approach: A newly-designed interdisciplinary cognitive science curriculum is presented that is based on a constructivist epistemology. We suggest that a careful construction of the learning space is a necessary requirement. The MEi:CogSci curriculum is designed and structured in such a way that enables didactical measures that allow for collaborative construction of meaning by discussing concepts, methods and terminologies and also hidden assumptions. Findings: The experience with four cohorts of students has shown that a truly interdisciplinary approach to cognitive science demands a different attitude towards knowledge as well as towards teaching and learning on both sides: the teacher and the student. The research orientation promotes an understanding of knowledge as something that is actively constructed, rendering the role of the teacher that of a co-learner rather than a transmitter of knowledge, thereby also changing the responsibility of students.

Social constructivists claim that many phenomena that we normally assume to exist independently are really just created by collective human action, thought and language. Constructivists deploy a number of sophisticated philosophical arguments to support this thesis and, in so far as their reasoning typically serves an ulterior ideological purpose, it may fairly be called applied philosophy. The goal is to change various aspects of the existing order of things; constructivist arguments are used to show that this order is a human (...) creation and is hence modifiable by human effort. A number of such “deconstructive” agendas are presented. The first deals with natural science and its privileged societal status; the next critiques orthodox Marxism; the third is the feminist campaign against patriarchal society. While these critical efforts have had considerable impact, their protagonists have been less successful in constructing alternatives to the items deconstructed. (shrink)

Every computable function has to be continuous. To develop computability theory of discontinuous functions, we study low levels of the arithmetical hierarchy of nonuniformly computable functions on Baire space. First, we classify nonuniformly computable functions on Baire space from the viewpoint of learning theory and piecewise computability. For instance, we show that mind-change-bounded learnability is equivalent to finite View the MathML source2-piecewise computability 2 denotes the difference of two View the MathML sourceΠ10 sets), error-bounded learnability is equivalent to finite View (...) the MathML sourceΔ20-piecewise computability, and learnability is equivalent to countable View the MathML sourceΠ10-piecewise computability . Second, we introduce disjunction-like operations such as the coproduct based on BHK-like interpretations, and then, we see that these operations induce Galois connections between the Medvedev degree structure and associated Medvedev/ Muchnik-like degree structures. Finally, we interpret these results in the context of the Weihrauch degrees and Wadge-like games. (shrink)

Many neo-Aristotelians argue that practical identities are normative, that is, they provide us with reasons for action and create binding obligations. Kantian constructivists agree with this insight but argue that contemporary Aristotelians fail to fully justify it. Practical identities are normative, Kantian constructivists contend, but their normativity necessarily derives from the normativity of humanity. In this paper, I shed light on this underexplored similarity between neo-Aristotelian and Kantian constructivist accounts of the normativity of practical identities, and argue that both ultimately (...) fail. I end by suggesting an alternative justification of the claim that practical identities are normative. (shrink)

Consecutive constructivism is a moral and political theory which mitigates structural injustice by securing individuals' perception of private morality--that is, inventing procedural devices to make people enhance their moral consciousness--and, at the same time, encourages people to voluntarily concern themselves with procedural justice and public morality. The crucial reason for this position is that a detouring method of not directly dealing with the problem of justice but rather discussing the problem of morals is required to avoid the lucid criticisms (...) of statists that the sovereign ruling states with authority or the world government does not exist. This book suggests a new approach to the problem of global justice, termed here consecutive constructivism. It provides a way of coping with procedural justice at the global level, while also alleviating the problem of structural injustice insofar as it exacerbates procedural injustice. Acknowledging the fact that the discussion of global justice is difficult in a world constituted of lots of sovereign states, it sketches out a political theory which begins with the problem of morals and then consecutively moves on to the matter of justice. The result is a novel normative theory narrowing the gap between Neo-Westphalian and Post-Westphalian traditions. (shrink)

John Rawls's form of constructivism can easily be ramped up into a fullblown metaethics. In this chapter, the author explores an alternative interpretive framework, which basically inverts the roles that the construction of the original position and the reliance on reflective equilibrium play in Rawls's argument. The author sketches out the basic contours of Rawls's thinking if we treat constructivism as his method for theory construction and reflective equilibrium as his metaethics. Metaethics is clearly a part of moral (...) philosophy outside of moral theory. At every major turn in the articulation of Rawls's theory there is a new or more developed account of reflective equilibrium and in particular its justificatory role in the theory. Giving one's argument a form that allows it to more easily appeal to a particular audience, is the job of rhetoric. So it turns out that constructivism is not a metaethical position, but a rhetorical strategy. (shrink)

The idea to produce the current volume was conceived by Jiirgen Mittelstrass and Robert E. Butts in 1978. Idealist philosophers are wrong about one thing: the temporal gap separating idea and reality can be very long indeed - even ten or so years! Problems of timing were joined by personal problems and by the pressure of other professional commitments. Fortunately, James Brown agreed to cooperate in the editing of the volume; the infusion of his usual energy, good judgement and good-natured (...) promptness saved the volume and made its produc tion possible. Despite the delays, the messages of the papers included in the book have not gone stale. An extremely worthwhile exercise in international philosophical cooperation has come to fruition; the German constructivist philosophical position is here represented in papers in English that will make its contemporary importance available to a larger audience. The editors owe thanks to many persons. All involved in the project owe much to the interest and support of Nicholas Rescher, a friend of the undertaking from the time of its inception. My review of the translations was helped immensely by Andrea Purvis' careful copy editing of the typescript. Most of all, however, we owe gratitude and admiration for the tireless efforts on behalf of this enterprise to Jiirgen Mittelstrass. (shrink)

Open peer commentary on the article “Towards a Dialogue Among Constructivist Research Programs” by Gastón Becerra & José Antonio Castorina.
