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.

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)

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)

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.

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.

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)

Over the past several decades, philosophers have grown to recognize the role played by frameworks and models in the construction of human knowledge. Further, they have paid increasing attention to the origins of knowing processes in social and historical contexts of human practical activities, and to social transformation of the frameworks over time. In a series of original essays by prominent philosophers, Constructivism and Practice advances the understanding of the role of construction and model creation, reflects on the relationship (...) of these models to social practices, and considers whether our modes of knowing themselves have a history. These questions are thoughtfully considered in the light of the 'historical epistemology' first developed by Marx Wartofsky.

Maya Zehfuss critiques constructivist theories of international relations (currently considered to be at the cutting edge of the discipline) and finds them wanting and even politically dangerous.

She argues that scholars are limiting their abilities to act responsibly in international relations by looking towards (...) class='Hi'>constructivism as the future. (shrink)

The term “constructivism” names a family of political, moral and metaethical views that, in general terms, regard some or all normative claims as valid in virtue of being outcomes of a “procedure of construction” in which actual or hypothetical agents react to, choose, or otherwise settle on principles of justice, moral rules, values, etc. Traditionally, moral validity or justifiability was thought to depend on God, the Forms, or some other independent moral order. Various procedures of a different, epistemological, sort (...) were then proposed to help us gain access to the moral facts, which were thought to exist independently of us (e.g., we might need to undergo physical and mental training of the sort described in Plato's Republic or learn how to reflect in a “calm, cool hour”). Constructivists, by contrast, think that there are certain procedures that are not designed to discover which normative claims are already valid. For them, the validity of some or all reasons, principles, values or other normative claims consist in being the result of a procedure of construction. For example, Rousseau (1997) held that states are legitimate just in case and because they would be agreed to by reasonable people who were concerned to advance their own basic interests in freedom, self-improvement, and happiness, while Locke (1998) argued that governments are legitimate just in case and because free and equal (male, property-owning) people in a state of equal freedom actually agreed to them so long as those governments remain within the confines of natural law.

My aim in this paper is to consider a particular line of criticism that has been used by constructivists to argue against moral realism, which is to claim that if moral realism were true, this would then threaten or undermine our autonomy as agents. I call this the argument from autonomy. I argue that the best way to understand the argument from autonomy is to relate it to the issue of obligatoriness; but that there are a variety of strategies to (...) be explored concerning obligation before it is clear that the right response to this issue is a constructivist one, or that the realist is hereby compelled to surrender their position.

Purpose: Describing how radical constructivism was introduced to communication science and analyzing why it has not yet become a mainstream endeavour. Situation: Before radical constructivism entered the relevant debates in communication sciences, moderate constructivist positions had already been developed. Problem: Radical constructivists’ argumentation has often been provocative and exaggerating in style, and extreme in its position. This has provoked harsh reactions within the mainstream scientific community. Several argumentative strategies have been used to degrade radical constructivist arguments and their (...) relevance. Solution: Beyond such rhetorical devices, radical constructivism has become established within the field of communication science, although it has not become mainstream. One should probably not even wish to make radical constructivism a mainstream approach in case it loses its sceptical ability for second-order-observation. (shrink)

Upshot: All my commentators have focused, with varying emphasis, on issues related to: (a) cognitive vs. non-cognitive knowledge, (b) the role of the social environment, and (c) ethical responsibility. These issues are addressed in this response.

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.

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)

In this paper I provide an epistemological context for Artificial Life projects. Later on, the insights which such projects will exhibit may be used as a general direction for further Artificial Life implementations. The purpose of such a model is to demonstrate by way of simulation how higher cognitive structures may emerge from building invariants by simple sensorimotor beings. By using the bottom-up methodology of Artificial Life, it is hoped to overcome problems that arise from dealing with complex systems, such (...) as the phenomenon of cognition. The research will lead to both epistemological and technical implications. The proposed ALife model is intended to point out the usefulness of an interdisciplinary approach including methodological approaches from disciplines such as Artificial Intelligence, Cognitive Science, Theoretical Biology, and Artificial Life. I try to put them in one single context. The epistemological background which is necessary for this purpose comes from the ideas developed in both epistemological and psychological Constructivism. The model differs from other ALife approaches— and is somewhat radical in this sense—as it tries to start on the lowest possible level, i.e. avoids several a priori assumptions and anthropocentric ascriptions. Due to this characterization, the project may be alternatively viewed as testing the complementary relationship between epistemology and methodology. (shrink)

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.

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)

This essay addresses the relationship between Kant's theory of moral motivation and theories of normativity. Constructivist or "ideal agent" theories of normativity claim that what makes a principle normative is that rational agents endorse or possess a motive of a certain kind to comply with it, or that they endorse or possess such a motive to comply with it insofar as they are rational. Korsgaard has argued that Kant's "motivational analysis" of the concept of obligation in Grundlegung I provides an (...) argument for such a constructivist theory of normativity. In this examination of Korsgaard's argument, I defend two important modifications of the concept of "intrinsic normativity" and suggests that once these modifications are made, the motivational analysis argument fails to establish the constructivist claim that the normative authority of the supreme principle of morality is constituted by or depends solely upon agents' motivational states. While Kant's motivational analysis helps to reveal the nature of the alleged internal relation between the supreme principle of morality and the nature of the rational will, it does not demand the adoption of a constructivist theory of normativity.

This volume presents twelve original papers on the idea that moral objectivity is to be understood in terms of a suitably constructed social point of view that all can accept.

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)

Our paper aims to explore the effectiveness of a constructivist approach to the teaching of engineering ethics through case studies, by putting forward a contextualization of the much discussed case study “Cutting Road Side Trees” [12] in light of the constructivist frame suggested by Jonassen [8]. First, we briefly analyse how the use of case studies for the teaching of engineering ethics eludes the complexity of the engineering professional environment before arguing that constructivism is a learning theory that can (...) help to address this complexity. The final section proposes a constructivist reworking of the case method in a manner that aims to correct the deficiencies identified, followed by a discussion of the results of applying the contextualized exercise to First Year group of engineering students. The key findings reveal that the contextualized scenario enhances, in some respects, students’ understanding of the social dimension of the engineering profession. (shrink)

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, I argue that a form of moral constructivism inspired by Hume's Enquiry yields a plausible response to the problem of relativity. Though this problem can be stated in many different ways, I argue that a Humean constructivism is far more universal in scope that Hume's positions are often taken to be. In addition, I argue that where Hume's position does imply a limited scope, this limitation is perfectly appropriate. I discuss four iterations of the relativity (...) problem(s) here: the incorrigibility of local practices (local practices relativism), the relativity of fundamental moral principles (local principles relativism), the contingency of moral principles (modal relativism), and, in a short postscript, the limited scope of moral normativity (normative relativism). Humean Constructivism, I argue, delivers the proper verdict for each of these purported problems. (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.

Political Constructivism is concerned with the justification of principles of political justice in the face of pluralism. Contemporary accounts of multiculturalism, pluralism and diversity have challenged the capacity of political theory to impartially justify principles of justice beyond the boundaries of particular communities. In this original account, Peri Roberts argues that political constructivism defends a conception of objective and universal principles that set normative limits to justifiable political practice. _Political Constructivism_ explores this understanding in two ways. Firstly, by (...) engaging with constructivist thinkers such as John Rawls and Onora O’Neill in order to lay out a basic understanding of what constructivism is. Secondly, the author goes on to defend a particular account of political constructivism that justifies a universal primary constructivism alongside the many secondary constructions in which we live our everyday lives. In doing so he outlines an understanding of principled pluralism which accepts diversity whilst at the same time recognising its limits. This volume will be of particular interest to students and researchers of political theory and political philosophy. (shrink)

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)

Two varieties of constructivism are distinguished. In part 1, the psychological or “radical” constructivism of von Glasersfeld is discussed. Despite its dominant influence in science education, radical constructivism has been controversial, with challenges to its principles and practices. In part 2, social constructivism is discussed in the sociology of scientific knowledge. Social constructivism has not been primarily concerned with education but has the most direct consequences in view of its challenge to the most fundamental, traditional (...) assumptions in the philosophy of science and to the practice of science itself.

Paul Boghossian’s recent book, Fear of Knowledge offers an extended argument against some forms of contemporary anti-realism and, by implication, an argument for realism. The intended audience is philosophers with metaphysical and epistemological interests, argumentation theorists might be most engaged by it because while the book is flawed as an argument, it makes a positive contribution when read as a discourse about argument. The main flaw is the uncharitable readings of Kuhn, Rorty, and Later Wittgenstein that can drive even wannabe (...) realists to their defense. The great contribution is delving deeply into the foundations of reason and rationality without getting caught in circularity, paradox, or regress. (shrink)
