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.

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)

One of the most familiar arguments for expressivist metaethics is the claim that the rival theory, moral realism, cannot provide a satisfying explanation of why moral properties supervene on natural properties. Non-cognitivism, however, has its own problems explaining supervenience. Expressivists try to establish supervenience either by second-order disapproval of type-inconsistent moral evaluations or by pragmatic considerations. But disapproval of inconsistency is merely a contingent attitude that people happen to have; and pragmatic justification does not allow for appraisers to take their (...) own moral attitudes seriously enough. What has been overlooked is a third alternative. The metaethical theory that can best account for supervenience is neither realist nor non-cognitivist but an objectivist version of constructivism. On the constructivist theory, right and wrong are determined by the principles that people would (hypothetically) consent to under ideal conditions. Type-consistency is a required feature of any principles regulating our conduct, if they are to be freely agreed to by ideally rational people. (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.

In recent times, representation theory has become one of the most productive and interesting sub-fields in democratic theory. Arguably, the most important theoretical innovation are the so-called ‘constructivist’ approaches to political representation. These approaches play a central role in Creating Political Presence: The New Politics of Democratic Representation and The Constructivist Turn in Political Representation, two impressive volumes that take stock of the state of the art in representation theory. I discuss the two volumes by focusing on three broader and (...) interconnected themes: the problem that constructivism is meant to respond to, the tendency of representation theorists to expand the possibilities of representation as broadly as possible, and the normative aspects of political representation and how constructivists deal with them.

Many people think that if you're uncertain about which moral theory is correct, you ought to maximize the expected choice-worthiness of your actions. This idea presupposes that the strengths of our moral reasons are comparable across theories – for instance, that our reasons to create new people, according to total utilitarianism, can be stronger than our reasons to benefit an existing person, according to a person-affecting view. But how can we make sense of such comparisons? In this article, I introduce (...) a constructivist account of intertheoretic comparisons. On this account, such comparisons don't hold independently of facts about morally uncertain agents. They're simply the result of an ideal deliberation in terms of certain epistemic norms about what you ought to do in light of your uncertainty. If I'm right, this account is metaphysically more parsimonious than some existing proposals, and yet has plausible and strong implications. (shrink)

Constructivism is at the heart of a pedagogical philosophy going back to Vico, whose view of the interrelationship of the arts and sciences sought to reconstitute the classical paideia. The Vichian idea that human beings can only know the truth of what they themselves have made has theoretical and practical consequences for Vico's pedagogy and view of the university. Vico's ideas on education are extended in the modern period by such thinkers as Cassirer, Piaget and Bateson. At the basis (...) of Cassirer's pedagogical philosophy is his theory of the symbol, the symbol being a universal and transcendent modality in culture. The result of this unifying theory is that symbolism, which is pervasive across the disciplines, provides a moral and ethical means for integrating communication about teaching. Cassirer's thought is compatible with Piaget's, which emphasizes the pluralism of experience and the role of dynamic learning in the construction of meaningful order. Piaget's constructivism assumes that an operational bridge exists to link together the hard sciences, the human sciences, and the historical disciplines. This systems view of epistemological matters is similar in many respects to the one advanced by Gregory Bateson, which is explored in the paper's final section. (shrink)

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)

This chapter discusses some of the central theoretical perspectives on culture and cultural practices implied in Pragmatism and interactive constructivism. The first part of the chapter highlights three major perspectives on cultural theory to be found in Dewey's thought: culture and experience, culture and habit, and culture and communication. The chapter then compares basic conceptual tools and interpretive approaches and shows that Dewey's work continues to provide fundamental resources in this field. Through this connection, it presents a brief introduction (...) to theories of discourse and power and discusses some implications for current controversies regarding multiculturalism. It argues that Dewey's Pragmatism and the Cologne program of interactive constructivism share a robust interest in culture and cultural diversity. (shrink)

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

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)

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 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)

In the title of his 1980 Dewey Lectures, John Rawls announced that his theory of justice as fairness could be described as an example of “Kantian Constructivism in Moral Theory” (KC). Rawls flirted around 1980 with a strong commitment to Kantian autonomy, only to abandon it as unnecessary to the justification of his theory of justice. The chapter argues that this supposed opposition is based on a serious misunderstanding of Rawls's intellectual trajectory, and especially of the way he understands (...) the Kantian elements of his theory. It shows that, against the assumptions of the familiar debates, Rawls in and after KC, consistently held that the practical aims of constructivism and the philosophical goal of a fully rational justification are not in any sort of tension. Rawls's claims in Political Liberalism and after, and especially his distinction between his political and Kant's moral constructivism, in no way undermine this argument. (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)

Since the appearance of Hayden White's seminal work Metahistoryin 1973, constructivist thought has been a key force within theory of history and has at times even provided inspiration for historians more generally. Despite the radical theoretical shift marked by constructivism and elaborated in detail by its proponents, confusion regarding many of its practical and ethical consequences persists, however, and its position on truth and meaning is routinely misconstrued. To remedy this situation, The Work of Historyseeks to mediate between constructivist (...) theory and history practitioners' intuitions about the nature of their work, especially as these relate to the so-called fact-fiction debate and to the literary challenges involved in the production of historical accounts. In doing so, the book also offers much-needed insight into debates about our experiential relations with the past, the political use of history and the role of facts in the contestation of power.

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)

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)

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)

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)

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.

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.

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)

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)

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.

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.

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)

The main focus of this paper ison ways in which Kantian philosophy can informproponents and opponents of constructivismalike. Kant was primarily concerned withreconciling natural and moral law. His approachto this general problematic was to limit andseparate what we can know about things(phenomena) from things as they are inthemselves (noumena), and to identify moralagency with the latter. Revisiting the Kantianproblematic helps to address and resolve longstanding epistemological concerns regardingconstructivism as an educational philosophy inrelation to issues of objectivity andsubjectivity, the limits of (...) theoretical andpractical reason, and the relation betweenhuman experience and the world. It also servesto address ethical concerns regardingliberation from limited self-interests andcontexts conditioned by localised beliefs andinclinations. In light of revisiting theKantian problematic, both Glasersfeld's radicalview of constructivism and Jardine's socialcritique of constructivism are found wanting.Beyond constructivism, Kant's distinctionbetween phenomena and noumena and the limits ofreason that follow from it are brieflyconsidered in terms of Merleau-Ponty's noveldouble-embodied notion of flesh as anontological primitive – as a matter of beingboth in, and of, the world – with an aim tomore intimate connections between epistemologyand ethics.

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)

Provability, Computability and Reflection.

The Kantian strain of practical constructivism (through Rawls, 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 outlook. In this essay, I explore a different variety of practical constructivism, what I call “Aristotelian constructivism”. My aim is to establish conceptual space for this form of constructivism by indicating in what ways Aristotelian constructivism agrees with its Kantian counterparts and in (...) what ways it differs. I claim that it is, in 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.

The core idea of social constructivism in mathematics is that mathematical entities are social constructs that exist in virtue of social practices, similar to more familiar social entities like institutions and money. Julian C. Cole has presented an institutional version of social constructivism about mathematics based on John Searle’s theory of the construction of the social reality. In this paper, I consider what merits social constructivism has and examine how well Cole’s institutional account meets the challenge of (...) accounting for the characteristic features of mathematics, especially objectivity and applicability. I propose that in general social constructivism shows promise as an ontology of mathematics, because the view can agree with mathematical practice and it offers a way of understanding how mathematical entities can be real without conflicting with a scientific picture of reality. However, I argue that Cole’s specific theory does not provide an adequate social constructivist account of mathematics. His institutional account fails to sufficiently explain the objectivity and applicability of mathematics, because the explanations are weakened and limited by the three-level theoretical model underlying Cole’s account of the construction of mathematical reality and by the use of the Searlean institutional framework. The shortcomings of Cole’s theory give reason to suspect that the Searlean framework is not an optimal way to defend the view that mathematical reality is socially constructed. (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.

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)

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.

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)

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)

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)
