'What is real?' has been one of the key questions of philosophy since its beginning in antiquity. But it is not just a question that philosophers ask. This Very Short Introduction discusses what reality is by looking at a variety of arguments, theories, and thought-experiments from philosophy, physics, and cognitive science.

One of our great contemporary scientists presents ten insights that illuminate what every thinking person needs to know about what the world is and how it works. Nobel Prize winner Frank Wilczek's Fundamentals is built around a simple but profound idea: the models of the world we construct as children are practical and adequate for everyday life, but they do not bring in the surprising and mind-expanding revelations of modern science. To do that, we must look at the world anew, (...) combining clear thinking with an openness to wonder. This "born again" world is in many ways larger, fuller, and much stranger than it appears. Through an exploration of space, time, matter, and ideas--and equipped with facts, questions, and brilliant speculations--Wilczek guides us through the past, present, and future of fundamental science. Readers will emerge with an expanded vision of our universe. Author Bio: Frank Wilczek won the Nobel Prize in Physics in 2004 for work he did as a graduate student. He was among the earliest MacArthur fellows, and has won many awards both for his scientific work and his writing. He is the author of A Beautiful Question, The Lightness of Being, Fantastic Realities, Longing for the Harmonies, and hundreds of articles in leading scientific journals. His "Wilczek's Universe" column appears regularly in the Wall Street Journal. Wilczek is the Herman Feshbach Professor of Physics at the Massachusetts Institute of Technology, founding director of the T. D. Lee Institute and chief scientist at the Wilczek Quantum Center in Shanghai, China, and a distinguished professor at Arizona State University and Stockholm University. (shrink)

Artificial intelligence has historically been conceptualized in anthropomorphic terms. Some algorithms deploy biomimetic designs in a deliberate attempt to effect a sort of digital isomorphism of the human brain. Others leverage more general learning strategies that happen to coincide with popular theories of cognitive science and social epistemology. In this paper, I challenge the anthropomorphic credentials of the neural network algorithm, whose similarities to human cognition I argue are vastly overstated and narrowly construed. I submit that three alternative supervised learning (...) methods—namely lasso penalties, bagging, and boosting—offer subtler, more interesting analogies to human reasoning as both an individual and a social phenomenon. Despite the temptation to fall back on anthropomorphic tropes when discussing AI, however, I conclude that such rhetoric is at best misleading and at worst downright dangerous. The impulse to humanize algorithms is an obstacle to properly conceptualizing the ethical challenges posed by emerging technologies. (shrink)

When I take off my glasses, the world looks blurred. When I put them back on, it looks sharpedged. I do not think that the world really was blurred; I know that what changed was my relation to the distant physical objects ahead, not those objects themselves. I am more inclined to believe that the world really is and was sharp-edged. Is that belief any more reasonable than the belief that the world really is and was blurred? I see more (...) accurately with my glasses on than off, so visual appearances when they are on have some cognitive priority over visual appearances when they are off. If I must choose which kind of visual appearance to take at face value, I will choose the sharp-edged look. But what should I think when I see a mist, which looks very blurred however well I am seeing? Indeed, why choose to take any of the looks at face value? Why not regard all the choices as illegitimate projections of ways of seeing the world onto the world itself? (shrink)

Value, Reality, and Desire is an extended argument for a robust realism about value. The robust realist affirms the following distinctive theses. There are genuine claims about value which are true or false--there are facts about value. These value-facts are mind-independent - they are not reducible to desires or other mental states, or indeed to any non-mental facts of a non-evaluative kind. And these genuine, mind-independent, irreducible value-facts are causally efficacious. Values, quite literally, affect us. These are not particularly (...) fashionable theses, and taken as a whole they go somewhat against the grain of quite a lot of recent work in the metaphysics of value. Further, against the received view, Oddie argues that we can have knowledge of values by experiential acquaintance, that there are experiences of value which can be both veridical and appropriately responsive to the values themselves. Finally, these value-experiences are not the products of some exotic and implausible faculty of "intuition." Rather, they are perfectly mundane and familiar mental states - namely, desires. This view explains how values can be "intrinsically motivating," without falling foul of the widely accepted "queerness" objection. There are, of course, other objections to each of the realist's claims. In showing how and why these objections fail, Oddie introduces a wealth of interesting and original insights about issues of wider interest--including the nature of properties, reduction, supervenience, and causation. The result is a novel and interesting account which illuminates what would otherwise be deeply puzzling features of value and desire and the connections between them. (shrink)

This book highlights Kant's fundamental contrast between the mechanistic and dynamical conceptions of matter, which is central to his views about the foundations of physics, and is best understood in terms of the contrast between objects of sensibility and things in themselves.

Lucy Allais presents an original interpretation of Kant's transcendental idealism. She argues that his distinction between things in themselves and things as they appear to us has both epistemological and metaphysical components. Kant is committed to a genuine idealism about things as they appear to us, but this is not a phenomenalist idealism. He is committed to the claim that there is an aspect of reality that grounds mind-dependent spatio-temporal objects, and which we cannot cognize, but he does not (...) assert the existence of distinct non-spatio-temporal objects. On Allais's account, we cannot understand Kant's idealism without a clear account of his notion of intuition and of the role of intuition in cognition: she understands Kantian intuitions as representations that give us acquaintance with the objects of thought. This enables us to make sense of Kant's central argument for his idealism in the Transcendental Aesthetic, and to see why he takes the complete idealist position to be established there. (shrink)

Remodel[l]ing Reality is an inquiry into Wittgenstein's notion of übersichtliche Darstellung and the phenomenon of installation in visual art. In a sense, both provide a perspicuous overview of a particular part of our complex world, but the nature of the overview differs. Although both generate knowledge, philosophy via the übersichtliche Darstellung gives us a view of how things stand for us, while the installation shows an unexpected, exiting point of view. The obvious we tend to forget and the ambiguity (...) of reality are related to each other in a dynamic way. It is in this reflexive dynamics that we constantly remodel our reality. Tools we use are our creative abilities and our powers of imagination. In our choices and solutions we show which aspects of reality we find important and how we communicate these values. The outcome of this investigation is a new perspective on the art of installation and a new insight in Wittgenstein's notion of übersichtliche Darstellung. Because of this combination, the book is itself an artwork: an InstallationPackage. The book is distributed by Ideabooks Amsterdam, Isbn 978 90 804240 3 6. Remodel[l]ing Reality is included in Special Collections, Allard Pierson Museum Amsterdam. (shrink)

Augmented reality (AR) technologies function to ‘augment’ normal perception by superimposing virtual objects onto an agent’s visual field. The philosophy of augmented reality is a small but growing subfield within the philosophy of technology. Existing work in this subfield includes research on the phenomenology of augmented experiences, the metaphysics of virtual objects, and different ethical issues associated with AR systems, including (but not limited to) issues of privacy, property rights, ownership, trust, and informed consent. This paper addresses some (...) epistemological issues posed by AR systems. I focus on a near-future version of AR technology called the Real-World Web, which promises to radically transform the nature of our relationship to digital information by mixing the virtual with the physical. I argue that the Real-World Web (RWW) threatens to exacerbate three existing epistemic problems in the digital age: the problem of digital distraction, the problem of digital deception, and the problem of digital divergence. The RWW is poised to present new versions of these problems in the form of what I call the augmented attention economy, augmented skepticism, and the problem of other augmented minds. The paper draws on a range of empirical research on AR and offers a phenomenological analysis of virtual objects as perceptual affordances to help ground and guide the speculative nature of the discussion. It also considers a few policy-based and designed-based proposals to mitigate the epistemic threats posed by AR technology. (shrink)

Practical Reality is a lucid original study of the relation between the reasons why we do things and the reasons why we should. Jonathan Dancy maintains that current philosophical orthodoxy bowdlerizes this relation, making it impossible to understand how anyone can act for a good reason. By giving a fresh account of values and reasons, he finds a place for normativity in philosophy of mind and action, and strengthens the connection between these areas and ethics.

Social reality is a key problem in the philosophy of social science. Outlining the major historical and contemporary issues raised by the social reality and social facts, this book has something to offer both philosophers and social scientists. To the former is shows how the well-worn topic of realism versus anti-realism assumes new and interestingly varied forms when social reality is substituted for physical reality. For the social scientist, the book offers conceptual clarification of key issues (...) in recent social science which are really philosophical issues. (shrink)

The history of humankind is full of examples that indicate a constant desire to make human beings more moral. Nowadays, technological breakthroughs might have a significant impact on our moral character and abilities. This is the case of Virtual Reality (VR) technologies. The aim of this paper is to consider the ethical aspects of the use of VR in enhancing empathy. First, we will offer an introduction to VR, explaining its fundamental features, devices and concepts. Then, we will approach (...) the characterization of VR as an “empathy machine,” showing why this medium has aroused so much interest and why, nevertheless, we do not believe it is the ideal way to enhance empathy. As an alternative, we will consider fostering empathy-related abilities through virtual embodiment in avatars. In the conclusion, however, we will, we will examine some of the serious concerns related to the ethical relevance of empathy and will defend the philosophical case for a reason-guided empathy, also suggesting specific guidelines for possible future developments of empathy enhancement projects through VR embodied experiences.

Originally published in 1989, Reclaiming Reality still provides the most accessible introduction to the increasingly influential multi-disciplinary and international body of thought, known as critical realism. It is designed to "underlabour" both for the sciences, especially the human sciences, and for the projects of human emancipation which such sciences may come to inform; and provides an enlightening intervention in current debates about realism and relativism, positivism and poststucturalism, modernism and postmodernism, etc. Elaborating his critical realist perspective on society, nature, (...) science and philosophy itself, Roy Bhaskar shows how this perspective can be used to undermine currently fashionable ideologies of the Right, and at the same time, to clear the ground for a reinvigorated Left. Reclaiming Reality contains powerful critiques of some of the most important schools of thought and thinkers of recent years—from Bachelard and Feyerabend to Rorty and Habermas; and it advances novel and convincing resolutions of many traditional philosophical problems. Now with a new introduction from Mervyn Hartwig, this book continues to provide a straightforward and stimulating introduction to current debates in philosophy and social theory for the interested lay reader and student alike. Reclaiming Reality will be of particular value not only for critical realists but for all those concerned with the revitalization of the socialist emancipatory project and the renaissance of the Marxist theoretical tradition. Roy Bhaskar is the originator of the philosophy of critical realism, and the author of many acclaimed and influential works including A Realist Theory of Science, The Possibility of Naturalism, Scientific Realism and Human Emancipation and Dialectic: The Pulse of Freedom. He is an editor of the recently published Critical Realism: Essential Readings and is currently chair of the Centre for Critical Realism. (shrink)

Chasing Reality deals with the controversies over the reality of the external world. Distinguished philosopher Mario Bunge offers an extended defence of realism, a critique of various forms of contemporary anti-realism, and a sketch of his own version of realism, namely hylorealism. Bunge examines the main varieties of antirealism - Berkeley's, Hume's, and Kant's; positivism, phenomenology, and constructivism - and argues that all of these in fact hinder scientific research. Bunge's realist contention is that genuine explanations in the (...) sciences appeal to causal laws and mechanisms that are not directly observable, rather than simply to empirical generalisations. Genuine science, in his view, is objective even when it deals with subjective phenomena such as feelings of fear. This work defends a realist view of universals, kinds, possibilities, and dispositions, while rejecting contemporary accounts of these that are couched in terms of modal logic and 'possible worlds.'.

What makes up reality, and how? What kinds of entity are fundamental to reality, and how do dependent entities depend on the fundamental ones? How does one entity metaphysically ground another? These questions are central to contemporary metaphysics. The papers in this collection, written by a new generation of metaphysicians, address these and related questions. They investigate the metaphysical concepts of grounding and fundamentality, and the relationship between the fundamental and all the other parts of reality. Together, (...) these papers represent the cutting-edge of a central topic in contemporary metaphysics. (shrink)

Are the objects and events that take place in Virtual Reality genuinely real? Those who answer this question in the affirmative are realists, and those who answer in the negative are irrealists. In this paper we argue against the realist position, as given by Chalmers (2017), and present our own preferred irrealist account of the virtual. We start by disambiguating two potential versions of the realist position—weak and strong— and then go on to argue that neither is plausible. We (...) then introduce a Waltonian variety of ictionalism about the virtual, arguing that this sort of irrealist approach avoids the problems of the realist positions, fits with a unifying theory of representational works, and offers a better account of the phenomenology of engaging in virtual experiences.

Fifteen leading philosophers explore metaphysical foundationalism, the idea that reality has an over-arching hierarchical structure ordered by relations of metaphysical dependence, where chains of entities ordered by those dependence relations terminate in something fundamental.

The identity predicate can be defined using second-order quantification: a=b =df ∀F(Fa↔Fb). Less familiarly, a dyadic sentential operator analogous to the identity predicate can be defined using third-order quantification: ϕ≡ψ =df ∀X(Xϕ↔Xψ), where X is a variable of the same syntactic type as a monadic sentential operator. With this notion in view, it is natural to ask after general principles governing its application. More grandiosely, how fine-grained is reality? -/- I will argue that reality is not structured in (...) anything like the way that the sentences we use to talk about it are structured. I do so by formulating a higher-order analogue of Russell’s paradox of structured propositions. I then relate this argument to the Frege-Russell correspondence. When confronted with the alleged paradox, Frege agreed that reality was not structured, but maintained that propositions (i.e. thoughts) were structured all the same. Russell replied that his paradox showed Frege’s theory of structured thoughts to be inconsistent, to which Frege replied that Russell’s argument failed to heed the distinction between sense and reference. Most recent commentators have sided with Russell. In defense of Frege, I establish the consistency of one version of his rejoinder. I then consider and reject some ways of resisting the argument against a structured conception of reality. I conclude that, if propositions are structured, this is because they correspond not to distinctions in reality, but rather to ways in which those distinctions can be represented. (shrink)

By questioning the validity of some of our basic concepts, such as space, object, and causality, quantum physics contributes quite decisively to the dramatic changes now taking place in our world picture. Veiled Reality provides a detailed view of the reasons why such a questioning arises, a survey of the corresponding conceptual and theoretical problems, and a comprehensive, up-to-date account, useful to scientists and epistemologists alike, of the various ways present-day physicists tackle these problems.The book deals with the E.P.R. (...) reality criterion, local causality, and quantum measurement including relativistic quantum collapse, decoherence theories, consistent histories approaches, and ontologically interpretable theories. Questions bearing on the connection between counterfactuality and realism, intersubjective agreement, and limits of the bearing of the verbs “to have” and “to be,” follow naturally from the analysis and are thoroughly examined. Finally, distinguishing between empirical reality and a veiled independent reality whose only knowable features are structural yields a clue to a plausible interpretation of current physics.Accessible to readers with only very elementary background in modern physics, Veiled Reality offers nonspecialists, including students in physics and philosophy, easy access to basic problems in the foundation of physics.

How is reality really manufactured? The idea of social construction has become a commonplace part of much social research, yet precisely what is constructed, how it is constructed, and what constructionism means are often left unclear or taken for granted. In this major work, Jonathan Potter explores the central themes raised by these questions. Representing Reality explores the different traditions in constructivist thought--including sociology of scientific knowledge; conversation analysis and ethnomethodology; and semiotics, poststructuralism, and postmodernism--to provide a lucid (...) introduction to several key strands of work that have overturned the way we think about facts and descriptions. Potter illustrates his points throughout with varied and engaging examples taken from newspaper stories, relationship counseling sessions, accounts of paranormal events, social workers' assessments of violent parents, informal talk between program organizers, political arguments, and everyday conversations. Representing Reality offers the student and scholar in social psychology, rhetoric and discourse, and related fields a critical introduction to constructivism. (shrink)

Contemporary physics, especially quantum theory, has raised profound questions about the relationship between the methods of science and the reality these methods seek to investigate. D'Espagnat investigates these questions as well as how we should answer them. Part I examines the practices of contemporary physicists and addresses the criticism philosophers of science have made of these practices. The doctrine of physical realism, adopted by most physicists and many philosophers of science, comprises Part II. Part III explores the consequences of (...) physical realism for our understanding of what science can seek to know of reality, and concludes by outlining the position contemporary physics indicates we should take.

Billy Dunaway develops and defends a framework for realism about morality. He defends the idea that moral properties are privileged parts of reality which are the referents for our moral terms. He suggests how it is that we can know about morality, and what the limits to moral disagreement are.

The study aimed to identify the reality of the use of social networks in the technical colleges in Palestine, where the variables of social networks were included. The analytical descriptive method was used in the study. A questionnaire consisting of (12) items was randomly distributed to college workers Technology in the Gaza Strip. The sample of the study consisted of (205) employees of these colleges. The response rate was 74.5%. The results showed a high degree of approval for the (...) dimensions of the social networks and a relative weight (74.15%) according to the perspective of the employees of the technical colleges in the Gaza Strip. The results of the study showed that there is a high level of social networking areas (site management and Website Content) in the technical colleges in the Gaza Strip. The field of site management ranked first with a relative weight of 74.91%, and second and last (Content Site) with a relative weight (73.38%). The results showed that there were differences between colleges in the use of social networks where the results showed that the most common colleges used these networks (UCAS) and the least used is (GTC). The results showed no differences between male and female employees in the use of social networks in technical colleges. The researchers suggest a number of recommendations, including: the need to raise awareness of the importance of Facebook and other social networking sites, through the holding of courses for employees in technical colleges, and to identify the ways to optimize the use of such sites, and the benefits of this use, and reflected positively on technical colleges. And the adoption of dealing with the various social networking sites as a reality, and the Palestinian and Arab technical colleges, use them in accordance with the objectives of technical colleges. Advise the Department of Technical Colleges to devote time to their presence on social networks to follow the public and respond to their queries. There is a need for the attention of decision-makers in technical colleges in social sites, because they are considered an important and effective means of communication, and the link between beneficiaries and decision-makers. There is a need to promote the use of modern electronic means of work and the need to increase the link of customers to the college through electronic services. (shrink)

Dreyfus examines the central ideas of Dharmakīrti, one of the most important Indian Buddhist philosophers, and their reception among Tibetan thinkers. During the golden age of ancient Indian civilization, Dharmakīrti articulated and defended Buddhist philosophical principles. He did so more systematically than anyone before his time (the seventh century CE) and was followed by a rich tradition of profound thinkers in India and Tibet. This work presents a detailed picture of this Buddhist tradition and its relevance to the history of (...) human ideas. Its perspective is mostly philosophical, but it also uses historical considerations as they relate to the evolution of ideas. (shrink)

This chapter investigates whether signs and their action, semiosis, are real. It critically surveys three arguments. The first argument consists in holding that semiosis must be real, because denying the reality of signs is self-defeating. This self-confirming status seems to imply that semiosis is the very means by which we partition the mind-independent and mind-dependent. One would then need to clarify this ontological neutrality or priority. The second argument consists in identifying an instance of sign-action that is mind-independent. Instead (...) of searching for abiotic semiosis, a more parsimonious approach is to ask whether we want reality to be what exists apart from minds in general or apart from human minds specifically. If we adopt the latter view, and if the action of signs can be shown to take place in the non-human realm, this would show that semiosis does not depend on us. One would then need to explain how humans can interpret all this while putting themselves out of the equation, so to speak. The third argument consists in saying that, despite its initial plausibility, the mind-dependent and mind-independent division is not clear-cut. This is because some conventional patterns can be informationally compressed in ways that are practically indistinguishable from genuinely mind-independent patterns. One would then need to clarify how the mind-dependent/mind-independent divide can admit of such hybrid cases. (shrink)

'Social construction' is a central metaphor in contemporary social science, yet it is used and understood in widely divergent and indeed conflicting ways by different thinkers. Most commonly, it is seen as radically opposed to realist social theory. Dave Elder-Vass argues that social scientists should be both realists and social constructionists and that coherent versions of these ways of thinking are entirely compatible with each other. This book seeks to transform prevailing understandings of the relationship between realism and constructionism. It (...) offers a thorough ontological analysis of the phenomena of language, discourse, culture and knowledge, and shows how this justifies a realist version of social constructionism. In doing so, however, it also develops an analysis of these phenomena that is significant in its own right. (shrink)

Are there objective moral truths, i.e. things that are morally right, wrong, good, or bad independently of what anybody thinks about them? To answer this question more and more scholars have recently turned to evidence from psychology, neuroscience, cultural anthropology, and evolutionary biology. This book investigates this novel scientific approach in a comprehensive, empirically-focused, and partly meta-theoretical way. It suggests that while it is possible for the empirical sciences to contribute to the moral realism/anti-realism debate, most arguments that have so (...) far been proposed fail (because they misrepresent, cherry-pick, or overlook the invalidity of (parts of) the available scientific evidence). The book’s main chapters address five prominent science-based arguments for or against the existence of objective moral truths: the argument from moral disagreement, the evolutionary debunking argument, the sentimentalist argument, the presumptive argument, and the projectivist argument. Thomas Pölzler investigates in which sense the underlying empirical hypotheses would have to be true in order for these arguments to work, and then shows how the available scientific evidence fails to support them. Finally, he makes suggestions as to how to test these hypotheses in a more valid way. Moral Reality and the Empirical Sciences is an important contribution to the moral realism/anti-realism debate that will appeal to philosophers and scientists interested in moral psychology and metaethics.

Are there things that are objectively right, wrong, good, bad, etc.: moral properties that are had independently of what we ourselves, our culture, God or any other subjects think about them? Philosophers have traditionally addressed this question from the “armchair.” In recent years, however, more and more participants of the debate have begun to appeal to evidence from science as well. This thesis examines such novel approaches. In particular, it asks what the empirical sciences can contribute to the moral realism/anti-realism (...) debate. My first aim is to show that it is possible for scientific evidence to bear on the question of the existence of objective moral properties. To see whether such contributions are also likely, I will then consider various prominent particular realist and anti-realist arguments: arguments based on hypotheses about ordinary people’s moral experience, the prevalence and persistence of moral disagreement, the evolution of morality, the relation of moral judgements to emotions, and the projection of values. If true, some of these empirical hypotheses would have metaethical implications. The problem with the arguments is, however, that the available scientific evidence does not support, or even contradicts these hypotheses. Only in ways other than have been suggested so far does the evidence considered in this thesis allow for a substantial metaethical conclusion. Finally, I will show that the relation between the empirical sciences and the question of the reality of moral values is actually much closer than commonly assumed. Not only do scientific hypotheses bear on metaethics, metaethical issues bear on the investigation of scientific hypotheses about morality as well. In order to further increase our understanding of what morality is, philosophers and scientists should therefore join forces and work together more closely than they have done so far. (shrink)

Scientific models are used to predict and understand the target phenomena in the reality. The kind of epistemic relationship between the model and the reality is always regarded by most of the philosophers as a representational one. I argue that, complementary to this representational role, some of the scientific models have a constructive role to play in altering and reconstructing the reality in a physical way. I hold that the idealized model assumptions and elements bestow the constructive (...) force of a model on the reality. By recognizing the physical constructive force of some scientific models, the merit of these models could be judged by how successful they are in the reality construction, rather than by the traditional criterion of model-world representation.

The notion of reality in the physical world has become, during the last century, somewhat problematic. The contrast between the simple and obvious reality of the innumerable instruments, machines, engines, and gadgets produced by our technological industry, which is applied physics, and of the vague and abstract reality of the fundamental concepts of physical science, as forces and fields, particles and quanta, is doubtlessly bewildering. There has already developed a gap between pure and applied science and between (...) the groups of men devoted to the one or the other activity, a separation that may lead to a dangerous estrangement. Physics needs a unifying philosophy, expressible in ordinary language, to bridge this gulf between "reality" as thought of in practice and in theory. I am not a philosopher but a theoretical physicist. I cannot provide a well balanced philosophy of science that would take due account of the ideas developed by differing schools, but I shall endeavor to formulate some ideas which have helped me in my own struggle with these problems.

It is commonly assumed that a virtual life would be less meaningful (perhaps even meaningless). As virtual reality technologies develop and become more integrated into our everyday lives, this poses a challenge for those that care about meaning in life. In this chapter, it is argued that the common assumption about meaninglessness and virtuality is mistaken. After clarifying the distinction between two different visions of virtual reality, four arguments are presented for thinking that meaning is possible in virtual (...) reality. Following this, four objections are discussed and rebutted. The chapter concludes that we can be cautiously optimistic about the possibility of meaning in virtual worlds. (shrink)

Social reality is currently a hotly debated topic not only in social science, but also in philosophy and the other humanities. Finn Collin, in this concise guide, asks if social reality is created by the way social agents conceive of it? Is there a difference between the kind of existence attributed to social and to physical facts - do physical facts enjoy a more independent existence? To what extent is social reality a matter of social convention. Finn (...) Collin considers a number of traditional doctrines which support the constructivist position that social reality is generated by our 'interpretation' of it. He also examines the way social facts are contingent upon the meaning invested in them by social agents; the nature of social convention; the status of social facts as symbolic; the ways in which socially shared language is claimed to generate the reality described, as well as the limitations of some of the over-ambitious popular arguments for social constructivism.
