Metaethical constructivism is the view that insofar as there are normative truths, they are not fixed by normative facts that are independent of what rational agents would agree to under some specified conditions of choice. The appeal of this view lies in the promise to explain how normative truths are objective and independent of our actual judgments, while also binding and authoritative for us. -/- Constructivism comes in several varieties, some of which claim a place within metaethics while (...) others claim no place within it at all. In fact, constructivism is sometimes defended as a normative theory about the justification of moral principles. Normative constructivism is the view that the moral principles we ought to accept are the ones that agents would agree to or endorse were they to engage in a hypothetical or idealized process of rational deliberation. -/- Metaethical constructivist theories aim to account for the nature of normative truths and practical reasons. They bear a problematic relation to traditional classifications of metaethical theories. In particular, there are disagreements about how to situate constructivism in the realism/antirealism debate. These disagreements are rooted in further differences about the definition of metaethics, the relation between normative and metaethical claims, and the purported methods pertinent and specific to metaethical inquiry. The question of how to classify metaethical constructivism will be addressed in what follows by focusing on the distinctive questions that constructivist theories have been designed to answer. Section 1 explains the origin and motivation of constructivism. Sections 2–4 examine the main varieties of metaethical constructivism. Section 5 illustrates related constructivist views, some of which are not proposed as metaethical accounts of all normative truths, but only of moral truths. Sections 6 and 7 review several debates about the problems, promise and prospects of metaethical constructivism. (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)

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)

Social constructivists maintain that we invent the properties of the world rather than discover them. Is reality constructed by our own activity? Or, more provocatively, are scientific facts--is everything --constructed? Social Constructivism and the Philosophy of Science is a clear assessment of this critical and increasingly important debate. Andre Kukla presents a comprehensive discussion of the philosophical issues involved and analyzes the strengths and weaknesses of a range of constructivist arguments, illustrating the divide between the sociology and the philosophy (...) of science through examples as varied as laboratory science, time, and criminality. He argues that current philosophical objections to constructivism are drastically inconclusive, while offering and developing new objections. Throughout, Kukla distinguishes between the social causes of scientific beliefs and the view that all ascertainable facts are constructed. (shrink)

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)

Discusses how to develop the idea that the normative truth is perspective-dependent with a broadly constructivist approach to metaethics - arguing in favor of developing this idea in terms of the idea that the normative truth is dependent upon the perspective of the assessor.

Relativist and constructivist conceptions of knowledge have become orthodoxy in vast stretches of the academic world in recent times. This book critically examines such views and argues that they are fundamentally flawed. The book focuses on three different ways of reading the claim that knowledge is socially constructed, one about facts and two about justification. All three are rejected. The intuitive, common sense view is that there is a way things are that is independent of human opinion, and that we (...) are capable of arriving at belief about how things are that is objectively reasonable, and is binding on anyone capable of appreciating the relevant evidence, regardless of their social or cultural perspective. Difficult as these notions may be, it is a mistake to think that recent philosophy has uncovered powerful reasons for rejecting them. (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.

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 and Practice advances the understanding of the role of construction and model creation and reflects on the relationship of these models to social practices.

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.

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)

In the contemporary metaethical debate, expressivist (Blackburn, Gibbard) and constructivist (Korsgaard, Street) views can be viewed as inspired by irrealist ideas from Hume and Kant respectively. One realist response to these contemporary irrealist views is to argue that they are inconsistent with obvious surface-level appearances of ordinary ethical thought and discourse, especially the fact that we talk and act as if there is ethical knowledge . In this paper, I explore some constructivist and expressivist options for responding to this objection. (...) My conclusion is that, although both constructivists and expressivists can capture other surface-level features of ethical thought and discourse, the possibility of ethical knowledge causes special problems for these versions of irrealism. I end with some comments about where I think irrealists should begin to look for a response to these special problems, which points, somewhat surprisingly, towards an alternative inferentialist form of irrealism about epistemic and ethical thought and discourse, which is inspired by Sellars.

Public reason theories are characterized by three conditions: constructivism, representation, and stability. Constructivism holds that justification does not rely on any antecedent moral or political values outside of the procedure of agreement. Representation holds that the reasons for the choice in the model must be rationally explicable to real agents outside the model. Stability holds that the principles chosen in the procedure should be stable upon reflection, especially in the face of diversity in a pluralistic society. Choice procedures (...) that involve at least two-stages with different information, as Rawls’s theory does, will be path-dependent and not meet the condition of representation since it will not be globally coherent. Attempts to solve this problem without eliminating the segmentation of choice in the procedure will run afoul of constructivism or stability. This problem is instructive because it highlights how public reason theories must evolve in the face of increased concerns about diversity. (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.

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.

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)

I describe a new problem for metaethical constructivism. The problem arises when agents make conflicting judgments, so that the constructivist is implausibly committed to denying they have any reason for any of the available options. The problem is illustrated primarily with reference to Sharon Street’s version of constructivism. Several possible solutions to the problem are explained and rejected.

Fully accessible to students and scholars alike, this engaging book introduces the constructivist approach to understanding world affairs.

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)

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)

The principal findings of experimental economics are that impersonal exchange in markets converges in repeated interaction to the equilibrium states implied by economic theory, under information conditions far weaker than specified in the theory. In personal, social, and economic exchange, as studied in two-person games, cooperation exceeds the prediction of traditional game theory. This book relates these two findings to field studies and applications and integrates them with the main themes of the Scottish Enlightenment and with the thoughts of F. (...) A. Hayek. (shrink)

This paper develops an interpretation of Nietzsche’s ethics and metaethics that reconciles his apparent antirealism with his engagement in normative discourse. Interpreting Nietzsche as a metaethical constructivist—as holding, to a first approximation, that evaluative facts are grounded purely in facts about the evaluative attitudes of the creatures to whom they apply—reconciles his vehement declarations that nothing is valuable in itself with his passionate expressions of a particular evaluative perspective and injunctions for the free spirits to create new values. Drawing on (...) Nietzsche’s broader epistemological and psychological views, I develop a distinctive, and genuinely Nietzschean, version of constructivism. On this account, evaluative properties are grounded in affective valuations of the new philosophers. The proposed interpretation synthesizes a variety of disparate features of Nietzsche’s writings and improves on existing interpretations in the literature. The resulting version of constr.. (shrink)

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.

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)

In this paper, I give a reconstruction of the so‐called Reinhold–Sidgwick objection and show that Korsgaard‐style Kantian constructivists are committed to two key premises of the underlying argument. According to the Reinhold–Sidgwick objection, the Kantian conception of autonomy entails the absurd conclusion that no one is ever morally responsible for a morally wrong action. My reconstruction of the underlying argument reveals that the objection depends on a third premise, which says that freedom is a necessary condition for moral responsibility. After (...) mapping the common replies to the objection, I demonstrate that none of these replies is available to Kantian constructivists. But they need not be committed to the absurd conclusion that no one is ever morally blameworthy. Kantian constructivists who want to resist the Reinhold–Sidgwick objection are well advised to subject the third premise of the underlying argument to critical scrutiny. (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)

There are at least two politically salient senses of “representation”—acting-for-others and portraying-something-as-something. The difference is not just semantic but also logical: relations of representative agency are dyadic (x represents y), while portrayals are triadic (x represents y as z). I exploit this insight to disambiguate constructivism and to improve our theoretical vocabulary for analyzing political representation. I amend Saward’s claims-based approach on three points, introducing the “characterization” to correctly identify the elements of representational claims; explaining the “referent” in pragmatic, (...) not metaphysical terms; and differentiating multiple forms of representational activity. This enables me to clarify how the represented can be both prior to representation and constituted by it, and to recover Pitkin’s idea that representatives ought to be “responsive” to the represented. These points are pertinent to debates about the role of representatives, the nature of representative democracy, and the dynamics of revolutionary movements. (shrink)

This paper explores two questions in moral philosophy that might at first seem unrelated. The first question is practical. While it’s not a truth we like to contemplate, each of us faces the eventual loss of everyone and everything we love. Is there a way to live in full awareness of that fact without falling into anxiety or depression, or resorting to one form or another of forgetfulness, denial or numbing out? The second question is metaethical. Is it possible to (...) vindicate a strong form of ethical objectivity without positing anything metaphysically or epistemologically mysterious? In this paper, I sketch a partially Buddhist-inspired metaethical view that would, if it could be made to work, give a positive answer to both questions. The overall view is too much to defend in one paper, so I focus on developing one limited part of it. I begin by characterizing the general constructivist strategy for vindicating the objectivity of ethics. After briefly discussing Christine Korsgaard’s Kantian implementation of the strategy, I suggest an alternative implementation. I explore the idea that every agent necessarily faces what I call the problem of attachment and loss. I close with some speculative remarks about why, even though the problem of attachment and loss presents itself in a different substantive guise to each individual agent, it is still possible that the best solution to the problem is universal, and involves taking up an ethical perspective on the world.

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.

Sharon Street defines her constructivism about practical reasons as the view that whether something is a reason to do a certain thing for a given agent depends on that agent’s normative point of view. However, Street has also maintained that there is a judgment about practical reasons which is true relative to every possible normative point of view, namely constructivism itself. I show that the latter thesis is inconsistent with Street’s own constructivism about epistemic reasons and discuss (...) some consequences of this incompatibility. (shrink)

Philosophers commonly wonder what a constructivist theory as applied to practical reasons might look like. For the methods or procedures of reasoning familiar from moral constructivism do not clearly apply generally, to all practical reasons. The paper argues that procedural specification is not necessary, so long as our aims are not first-order but explanatory. We can seek to explain how there could be facts of the matter about reasons for action without saying what reasons we have. Explanatory constructivism (...) must assurne constructive “norms of practical reasoning” which yield particular truths without assuming them. But philosophers often mistakenly assurne that only “formal” norms of reasoning could fulfill this role. The paper describes a further possibility: norms of reasoning can be “situation-specific” and yet retain truth-independent authority. Though we might doubt whether such norms can be independently defended, we should not doubt the possibility or coherence of constructivism about practical reasons. (shrink)

Context: The current situation in philosophy of science includes central, ongoing debates about realism and anti-realism. The same question has been central to the theorising of radical constructivism and, in particular, to its implications for educational theory. However the constructivist literature does not make significant contact with the most important, mainstream philosophical discussions. Problem: Despite its overwhelming influence among educationalists, I suggest that the “radical constructivism” of Ernst Glasersfeld is an example of fashionable but thoroughly problematic doctrines that (...) can have little benefit for practical pedagogy or teacher education. My critique has a positive goal: it is important to understand why constructivism has generated such severe polarization and disputation. A symptom of the problem is the concern with the most abstruse and obdurate problems of philosophy that have no conceivable bearing on educational practice or anything else, for that matter. The diagnosis is confirmed by those pedagogical recommendations that are allegedly derived from radical constructivism that are touted as revolutionary but are platitudes of common sense. I suggest that, ironically, this observation itself provides some pedagogical insight. Method: The approach adopted for the topic is critical, philosophical analysis of the various claims and theses of radical constructivism in the light of philosophy of science and psychology. Results: The findings of the paper are that central theoretical claims of constructivism are couched in an unclear and unnecessary jargon that obscures the implausibility or banality of these claims. Implications: The value of the paper lies in providing an analysis and critique of central, influential claims of radical constructivism both in relation to issues in epistemology and also in relation to the alleged bearing of these claims on pedagogy. It is suggested that, contrary to the claims of radical constructivists, there are few if any implications for practice and applications. (shrink)

The dissertation studies the mathematical strength of strict constructivism, a finitistic fragment of Bishop's constructivism, and explores its implications in the philosophy of mathematics. ;It consists of two chapters and four appendixes. Chapter 1 presents strict constructivism, shows that it is within the spirit of finitism, and explains how to represent sets, functions and elementary calculus in strict constructivism. Appendix A proves that the essentials of Bishop and Bridges' book Constructive Analysis can be developed within strict (...) constructivism. Appendix B further develops, within strict constructivism, the essentials of the functional analysis applied in quantum mechanics, including the spectral theorem, Stone's theorem, and the self-adjointness of some common quantum mechanical operators. Some comparisons with other related work, in particular, a comparison with S. Simpson's partial realization of Hilbert's program, and a discussion of the relevance of M. B. Pour-El and J. I. Richards' negative results in recursive analysis are given in Appendix C. ;Chapter 2 explores the possible philosophical implications of these technical results. It first suggests a fictionalistic account for the ontology of pure mathematics. This leaves a puzzle about how truths about fictional mathematical entities are applicable to science. The chapter then explains that for those applications of mathematics that can be reduced to applications of strict constructivism, fictional entities can be eliminated in the applications and the puzzle of applicability can be resolved. Therefore, if strict constructivism were essentially sufficient for all scientific applications, the applicability of mathematics of mathematics in science would be accountable. The chapter then argues that the reduction of mathematics to strict constructivism also reduces the epistemological question about mathematics to that about elementary arithmetic. The dissertation ends with a suggestion that a proper epistemological basis for arithmetic is perhaps a mixture of Mill's empiricism and the Kantian views. (shrink)

Most agree that when it comes to so-called 'first-order' normative ethics and political philosophy, constructivist views are a powerful family of positions. When it comes to metaethics, however, there is serious disagreement about what, if anything, constructivism has to contribute. In this paper I argue that constructivist views in ethics include not just a family of substantive normative positions, but also a distinct and highly attractive metaethical view. I argue that the widely accepted 'proceduralist characterization' of constructivism in (...) ethics is inadequate, and I propose what I call the 'practical standpoint characterization' in its place. I then offer a general taxonomy of constructivist positions in ethics. Since constructivism's standing as a family of substantive normative positions is relatively uncontested, I devote the remainder of the paper to addressing skeptics' worries about the distinctiveness of constructivism understood as a metaethical view. I compare and contrast constructivism with three other standard metaethical positions with which it is often confused or mistakenly thought to be compatible: realism; naturalist reductions in terms of an ideal response; and expressivism. In discussing the contrast with expressivism, I explain the sense in which, according to the constructivist, the distinction between substantive normative ethics and metaethics breaks down. I conclude by distinguishing between two importantly different debates about the mind-dependence of value. I argue that a failure to make this distinction is part of what explains why the possibility of constructivism as a metaethical view is often overlooked. (shrink)

The article offers an account of the constructivist methodology in ethics and political philosophy as 1) deriving from an agnostic moral ontology and 2) proposing intersubjective justifiability as the criterion of justification for normative principles. It then asks whether constructivism, conceived in this way, can respond to the challenge of “content skepticism about practical reason”, namely whether it can provide sufficiently precise normative guidance whilst remaining faithful to its methodological commitment. The paper critically examines to alternative way of meeting (...) this challenge, namely John Rawls's original position and O'Neill's Kantian constructivism, analyses what is problematic about both, and endorses a third, possibly intermediate model. Within such a model, the basic features of the original position are accepted, but in a flexible and heuristic manner, thereby accommodating some of O'Neill's concerns. (shrink)

Berger and Luckmann’s concept of “social construction” has been widely adopted in many fields of the humanities and social sciences in the half-century since they wrote The Social Construction of Reality. One field in which constructivism was especially provocative was in Science and Technology Studies, where it was expanded beyond the social domain to encompass the practices and contents of contemporary natural science. This essay discusses the relationship between social construction in STS and Berger and Luckmann’s original conception of (...) it, and identifies problems that arose from indiscriminate uses of constructivism.

Metaethical constructivism is one of the main movements within contemporary metaethics – especially among those with Kantian inclinations. But both the philosophical coherence and the Kantian pedigree of constructivism are hotly contested. In the first half of this article, I first explore the sense in which Kant's own views might be described as constructivist and then use the resulting understanding as a guide to how we might think about Kantian constructivism today. Along the way, I hope to (...) suggest that a fairly diverse range of views within contemporary metaethics – including some without any explicit allegiance to Kant – may be thought of as pursuing a version of the resulting strategy.

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. Zehfuss uses Germany's first shift toward using its military abroad after the end of the Cold War to illustrate why constructivism does not work and how it leads to particular analytical outcomes and forecloses others. She argues that scholars are limiting their abilities to act responsibly in international relations by looking towards (...) class='Hi'>constructivism as the future. (shrink)
