Introduction to Education provides pre-service teachers with an overview of the context, craft and practice of teaching in Australian schools as they commence the journey from learner to classroom teacher. Each chapter poses questions about the nature of teaching students, and guides readers though the Australian Professional Standards for Teachers. Incorporating recent research and theoretical literature, Introduction to Education presents a critical consideration of the professional, policy and curriculum contexts of teaching in Australia. The book covers theoretical topics in chapters (...) addressing assessment, planning, safe learning environments, and working with colleagues, families, carers and communities. More practical chapters discuss professional experience and building a career after graduation. Rigorous in conception and practical in scope, Introduction to Education welcomes new educators to the theory and practical elements of teaching, learning, and professional practice. (shrink)

In this paper, we consider what is commonly referred to as Leibniz’s argument for primitive concepts. After presenting and criticizing (in sections 1 and 2) one recent rather straightforward way of interpreting this argument, by Paul Lodge and Stephen Puryear, which takes the argument to be merely about the structure of concepts, we offer an alternative way of looking at the argument. We think it is best seen as being fundamentally about the relation between thought and reality. In order (...) to prepare the ground for our reconstruction (which we present in section 5), we have to introduce his view of ideas or concepts (section 3), as well as some metaphysical principles concerning reality-dependence (section 4).

According to one of Leibniz's theories of contingency a proposition is contingent if and only if it cannot be proved in a finite number of steps. It has been argued that this faces the Problem of Lucky Proof , namely that we could begin by analysing the concept ‘Peter’ by saying that ‘Peter is a denier of Christ and …’, thereby having proved the proposition ‘Peter denies Christ’ in a finite number of steps. It also faces a (...) more general but related problem that we dub the Problem of Guaranteed Proof . We argue that Leibniz has an answer to these problems since for him one has not proved that ‘Peter denies Christ’ unless one has also proved that ‘Peter’ is a consistent concept, an impossible task since it requires the full decomposition of the infinite concept ‘Peter’. We defend this view from objections found in the literature and maintain that for Leibniz all truths about created individual beings are contingent. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Literature as Sheltering the HumanJohn Durham PetersLiterature as Sheltering the Human, by Frederic Will; 203 pp. Lewiston, Maine: Edwin Mellen Press, 1993, $69.95.This volume contains thirteen essays by Frederic Will, poet, critic, ex-professor of literature, autobiographer, translator, man of letters. All concern the peculiar powers of literature to offer spiritual comfort and protection against the storms of life.A cluster of four theoretical essays begins the collection. The first (...) surveys Husserl’s intellectual offspring, Merleau-Ponty, Sartre, and Heidegger, and seeks in their philosophies of language a grounding for literature’s uniqueness. The second essay argues that everyday language is always on the verge of entropy, but at its best, can be sublimated into literature. The third essay is a fiction of a crazed lit professor trying to master “the whole of literature” (p. 41). The eternally elusive object of “literature” turns out to evoke erotic-aggressive energies. The fourth essay on “Influencing the Past” rehearses some Benjaminian and Borgesian themes about literary influence being not causality, but intertextual resonance.The next set of five essays—which Will calls a “testimony” (p. 133) or “hit and run theology” (p. 138)—forms the core of the book. They treat “sheltering the human” in Homer, the Bible, Sappho, the Bhagavad Gita, and the epistles of St. Paul. Each ponders an enclosure—a retreat from battle, a womb, an act of translation, an inward wrestle of conscience, the blood of Christ—made of words. To my mind, this is the best part of the book: a steady meditation, graced with poetic lines and steeped in wide learning, on the proposition that “poetically man dwells.” Here Will performs the humane survey of world-literature he elsewhere extolls.The concluding section explores the relation of literature to the other arts. There is an essay on the gradual discovery of the oral core of Greek literature, largely through German scholarship, and one on literature’s relation to the other arts, which argues for its unique centrality among human expressive forms, thanks to its alleged continuity with the essential human possession, language. The penultimate essay meditates on Adorno’s aesthetics of music (concluding on an affirmative note not quite in tune with Adorno’s gloomy musings on capitalism), and the grand finale muses on the relation of art to life, via the dubious conceit of “art” as a great resort hotel.The book is remarkable for an intense and bald aestheticism that is exceedingly rare today. Will calls literature “the ripest offspring of language” (p. 1) and is happy to speak of masterpieces, genius, revelation, the autonomy of art, classics, humanism, values lodged in the structure of the universe (p. 125), universal validity (p. 131), “texts high in redemptive claim” (p. 147), the continuing necessity of the classical tradition (p. 190), and the artist as all but a different species (p. 200). The faith in a totality called “literature” is, to put it lightly, out of season in the academy today. As Will, a confirmed foe of [End Page 387] academic politics and pedantry, might well suggest, this may speak in its favor. Though Will’s aestheticism may refresh, I cannot help but wonder with Adorno whether some forms of expression and faith are objectively impossible in certain eras. Can “literature” sustain credulity today as anything more than one among many remarkable human practices?There is something, if I may say it, sheltered about these essays. If, as J. S. Mill said, eloquence is heard but poetry is overheard, this work is more poetry than eloquence. It features repeated and unannounced autobiographical intrusions. The self-reflexive quality supplies ready phrases to the reviewer: Will calls himself a “fallen contemporary classicist,” praises “high-minded eclecticism” and favors those thinkers who “sensualize knowing.” These traits make for a rare voice singing in the cornfields of Iowa.John Durham PetersUniversity of IowaCopyright © 1995 The Johns Hopkins University Press...

As I write this, in November 1971, people are dying in East Bengal from lack of food, shelter, and medical caxc. The suffering and death that are occurring there now axe not inevitable, 1101; unavoidable in any fatalistic sense of the term. Constant poverty, a cyclone, and a civil war have turned at least nine million people into destitute refugees; nevertheless, it is not beyond Lhe capacity of the richer nations to give enough assistance to reduce any further suffering to (...) very small proportions. The decisions arid actions of human beings can prevent this kind of suffering. Unfortunately, human beings have not made the necessary decisions. At the individual level, people have, with very few exceptions, not responded to the situation in any signihczmt way. Generally speaking, people have not given large sums to relief funds; they have not written t0 their parliamentaxy representatives demanding increased government assistance; they have not demonstrated in the streets, held symbolic fasts, or done anything else directed toward providing thc refugees with the means to satisfy their essential needs. At thc government level, no govcrmmcnt has given the sort of massive aid that would enable the refugees to survive fm: more than a few days. Britain, for instance, has given rather more than most countries. It has, to date, given £14,750,000. For comparative purposes, B1~itain’s share of thc nonreccverabla development costs of the Anglo-French Concorde project is already in excess of £275,000,000, and on present estimates will reach £440,000,¤00. The implication is that the British government values a supersonic transport more than thirty times as.. (shrink)

The main concern of this essay is to make a case for the thesis that Leibniz conceived of his philosophy as a way of life in something like the sense articulated in the works of Pierre Hadot. On this view, philosophy was a type of conduct, or a mode of existing‐in‐the‐world, which had to be practised at each instant, with the goal of transforming the whole of the individual’s life. The essay also serves as an introduction to some of the (...) main themes in Hadot’s work. While it includes a brief discussion of a number of the central components of Leibniz’s philosophy conceived as a way of life, the essay does not aim to do so in great detail. Rather, it offers a manifesto and initial road map. (shrink)

Justin Garson introduces the distinction between two views on Madness we encounter again and again throughout history: Madness as dysfunction, and Madness as strategy. On the latter view, Madness serves some purpose for the person experiencing it, even if it’s simultaneously harmful. The strategy view makes intelligible why Madness often holds a certain allure – even when it’s prima facie terrifying. Moreover, if Madness is a strategy in Garson’s metaphorical sense – if it serves a purpose – it makes sense (...) to use consciously chosen strategies for living with Madness that doesn’t necessarily aim to annihilate or repress it as far as possible. In this paper, we use our own respective stories as case studies. We have both struggled to resist the allure of Madness, and both ended up embracing a kind of Pyrrhonian scepticism about reality instead of clinging to sane reality. (shrink)

This paper argues that a set of questioning attitudes are among the foundations of human and animal minds. While both verbal questioning and states of curiosity are generally explained in terms of metacognitive desires for knowledge or true belief, I argue that each is better explained by a prelinguistic sui generis type of mental attitude of questioning. I review a range of considerations in support of such a proposal and improve on previous characterizations of the nature of these attitudes. I (...) then broaden their explanatory scope to include a number of forms of exploratory search. The paper has three main goals: to characterize the nature of the questioning attitudes, outlining their causal role and type of content; to argue that they are fundamental components of the mind, being widespread among animals and not constructed during ontogeny out of other attitudes; and to suggest that they explain a great deal more behavior than one might think.

We propose a solution to the problem of logical omniscience in what we take to be its fundamental version: as concerning arbitrary agents and the knowledge attitude per se. Our logic of knowledge is a spin-off from a general theory of thick content, whereby the content of a sentence has two components: an intension, taking care of truth conditions; and a topic, taking care of subject matter. We present a list of plausible logical validities and invalidities for the logic of (...) knowledge per se for arbitrary agents, and isolate three explanatory factors for them: the topic-sensitivity of content; the fragmentation of knowledge states; the defeasibility of knowledge acquisition. We then present a novel dynamic epistemic logic that yields precisely the desired validities and invalidities, for which we provide expressivity and completeness results. We contrast this with related systems and address possible objections. (shrink)

What is ethics? Where do moral standards come from? Are they based on emotions, reason, or some innate sense of right and wrong? For many scientists, the key lies entirely in biology---especially in Darwinian theories of evolution and self-preservation. But if evolution is a struggle for survival, why are we still capable of altruism? In his classic study The Expanding Circle, Peter Singer argues that altruism began as a genetically based drive to protect one's kin and community members but (...) has developed into a consciously chosen ethic with an expanding circle of moral concern. Drawing on philosophy and evolutionary psychology, he demonstrates that human ethics cannot be explained by biology alone. Rather, it is our capacity for reasoning that makes moral progress possible. In a new afterword, Singer takes stock of his argument in light or recent research on the evolution of morality.--Publisher's description. (shrink)

Single-premise epistemic closure is the principle that: if one is in an evidential position to know that P where P entails Q, then one is in an evidential position to know that Q. In this paper, I defend the viability of opposition to closure. A key task for such an opponent is to precisely formulate a restricted closure principle that remains true to the motivations for abandoning unrestricted closure but does not endorse particularly egregious instances of closure violation. I focus (...) on two brands of epistemic theory that naturally incorporate closure restrictions. The first type holds that the truth value of a knowledge ascription is relative to a relevant question. The second holds that the truth value of a knowledge ascription is relative to a relevant topic. For each approach, I offer a formalization of a leading theory from the literature and use this formalization to evaluate the theory’s adequacy in terms of a precise set of desiderata. I conclude that neither theory succeeds in meeting these desiderata, casting doubt on the viability of the underlying approaches. Finally, I offer a novel variant of the topic-sensitive approach that fares better. (shrink)

This chapter provides an introduction to higher-order metaphysics as well as to the contributions to this volume. We discuss five topics, corresponding to the five parts of this volume, and summarize the contributions to each part. First, we motivate the usefulness of higher-order quantification in metaphysics using a number of examples, and discuss the question of how such quantifiers should be interpreted. We provide a brief introduction to the most common forms of higher-order logics used in metaphysics, and indicate a (...) number of questions which can be raised in such systems using logical vocabulary alone. Using a further example, we return to applications of higher-order logics in metaphysics. We also mention key developments in the history of higher-order logic as it pertains to metaphysics. Finally, we mention certain arguments which have been raised against the use of higher-order logic, and some ways of responding to them. (shrink)

First published in 1987. Routledge is an imprint of Taylor & Francis, an informa company.

Since its original publication in 1975, this groundbreaking work has awakened millions of people to the existence of "speciesism"—our systematic disregard of nonhuman animals—inspiring a worldwide movement to transform our attitudes to animals and eliminate the cruelty we inflict on them. In Animal Liberation, author Peter Singer exposes the chilling realities of today’s "factory farms" and product-testing procedures—destroying the spurious justifications behind them, and offering alternatives to what has become a profound environmental and social as well as moral issue. (...) An important and persuasive appeal to conscience, fairness, decency, and justice, it is essential reading for the supporter and the skeptic alike. (shrink)

I lay out the framework for my theory of sensory imagination in “Imagining as a guide to possibility.” Sensory imagining involves mental imagery , and crucially, in describing the content of imagining, I distinguish between qualitative content and assigned content. Qualitative content derives from the mental image itself; for visual imaginings, it is what is “pictured.” For example, visually imagine the Philadelphia Eagles defeating the Pittsburgh Steelers to win their first Super Bowl. You picture the greenness of the field and (...) the football’s brown oblong shape. Some of what you imagine isn’t explicitly pictured, however. That it is Sunday, that it is the Super Bowl: these facts are assigned. (shrink)

It is often said that there can be no conflict between the two great departments of human interest, called Religion and Science, because they deal with different themes in totally different ways, and therefore never overlap, so that there is no possibility of a fight—the kind of thing that used to be said about Nations before 1914. But this is an exaggeration; no human being can always be satisfied with any one department of knowledge; there are times when he must (...) seek a more comprehensive view. The alternative is to keep your thoughts from straying out of the region to which you are attending, and concentrate on one side only at a time. This has been the practice of many good people, and it is certainly one way of avoiding conflict.But it is not a philosophic or permanently satisfying way. Between the two great regions there is a frontier, and there squabbles and conflicts may occur, unless there be some way of reconciling the frontier inhabitants of the two regions. Our senses tell us that there is a material world full of things which we can investigate; our instincts and intuitions tell us that there is a mental and spiritual world where also we can feel at home. But the object of this article is to show that there is also an etheric or metetheral world, which spreads over both the other regions, and may be the means of reconciling them or of enabling us to attend to either or both without dislocation or shock.

Had I been asked any time last century to discourse to philosophers on a subject entitled “Beyond Physics,” I should have taken it as meaning “Metaphysics,” and have declined on the ground that they knew more about it than I did. But now that the subject has been suggested to me in the second quarter of the twentieth century, I realize that a certain number of physicists, especially mathematical ones, have gone beyond themselves in a semiphilosophical direction, have thrown our (...) old physical ideas into some confusion, and have devised a number of complicated abstractions which they seem able to deal with by recondite methods invented for other purposes by the pure mathematicians. Of these they do not attempt to form any mental image, and do not encourage us to try to do so. They mistrust the method of physical imagery, or what they call “models,” which constituted one of the main methods of investigation in the nineteenth century; they are content to deal with abstract symbols, which presumably represent something real, though they mistrust the term “reality,” and decline to define it. The younger modern physicists are content to work in a nebulous region of unknown and perhaps unknowable entities, remote from our ordinary conceptions and everyday experiences; so that, whereas the old idea of explanation consisted in trying to express mysterious or recondite phenomena in terms of something with which we were more familiar, they now point out that our apparent familiarity with those simpler things was more or less of an illusion, that they furnished no valid explanation at all, and that the physical and engineering conceptions or habits of thought on which we depended were largely misleading.

In the January number of the quarterly journal published by The British Institute of Philosophy, called Philosophy, Sir James Jeans with extraordinary ability has represented the view of the universe which may be held now in the twentieth century by a mathematician, and concludes that this representation contributes to and upholds an idealistic philosophy. Now with the contention that an idealistic philosophy is superior to any other, that is to say nearer the truth, we may be allowed to sympathize. Several (...) physicists, even in the nineteenth century, were inclined to sustain the essence of Berkeley's view, or to consider that metaphysical truth must lie somewhere in that direction. G. F. FitzGerald, for instance, was notably of that opinion. But he was not prepared on that account to abandon the physical view of existence, and to take refuge in mere mathematical abstractions.

Political decisions have the potential to greatly impact our lives. Think of decisions in relation to abortion or climate change, for example. This makes political legitimacy an important normative concern. But what makes political decisions legitimate? Are they legitimate in virtue of having support from the citizens? Democratic conceptions of political legitimacy answer in the affirmative. Such conceptions righly highlight that legitimate political decision-making must be sensitive to disagreements among the citizens. But what if democratic decisions fail to track what (...) there is most reason to do? What if a democratically elected government fails to take measures necessary to protect its population from threats related to climate change? Peter argues that the legitimacy of political decisions doesn't just depend on respect for the citizens' will; and defends a novel hybrid conception of political legitimacy, called the Epistemic Accountability conception. According to this conception, political legitimacy also depends on how political decision-making responds to evidence for what there is most reason to do. Grounds for Political Legitmacy starts with an overview of the main ways in which philosophers have thought about political legitimacy, and identifies the epistemic accountability conception as an overlooked alternative. It then develops the epistemic accountability conception of political legitimacy and discusses its implications for legitimate political decision-making. Considering the norms that should govern political debate, it examines the role of experts in politics, and probes the responsibilities of democratically elected political leaders and as well as of citizens.

This volume explores the use of higher-order logics in metaphysics. Seventeen original essays trace the development of higher-order metaphysics, discuss different ways in which higher-order languages and logics may be used, and consider their application to various central topics of metaphysics.

In the Western world it is usually taken as given that we all want happiness, and our educational arrangements tacitly acknowledge this. Happiness, Hope, and Despair argues, however, that education has an important role to play in deepening our understanding of suffering and despair as well as happiness and joy. Education can be uncomfortable, unpredictable, and unsettling; it can lead to greater uncertainty and unhappiness. Drawing on the work of Søren Kierkegaard, Miguel de Unamuno, Fyodor Dostoevsky, Simone Weil, Paulo Freire, (...) and others, Peter Roberts shows why these features of educational life need not be feared; to the contrary, they can be seen as a source of hope and human fulfilment. After years of negotiating an education system dominated by the language of competition, performance, and economic advancement, students and teachers often long for something different; they seek not just measurable success but also opportunities to ask searching questions of themselves and the world they encounter. Happiness, Hope, and Despair makes an important contribution toward meeting this need. It fosters a rethinking of the nature, purpose, and value of education, and opens up possibilities for further scholarly and professional inquiry. (shrink)

Peter Anstey presents a thorough and innovative study of John Locke's views on the method and content of natural philosophy. Focusing on Locke's Essay concerning Human Understanding, but also drawing extensively from his other writings and manuscript remains, Anstey argues that Locke was an advocate of the Experimental Philosophy: the new approach to natural philosophy championed by Robert Boyle and the early Royal Society who were opposed to speculative philosophy. On the question of method, Anstey shows how Locke's pessimism (...) about the prospects for a demonstrative science of nature led him, in the Essay, to promote Francis Bacon's method of natural history, and to downplay the value of hypotheses and analogical reasoning in science. But, according to Anstey, Locke never abandoned the ideal of a demonstrative natural philosophy, for he believed that if we could discover the primary qualities of the tiny corpuscles that constitute material bodies, we could then establish a kind of corpuscular metric that would allow us a genuine science of nature. It was only after the publication of the Essay, however, that Locke came to realize that Newton's Principia provided a model for the role of demonstrative reasoning in science based on principles established upon observation, and this led him to make significant revisions to his views in the 1690s. On the content of Locke's natural philosophy, it is argued that even though Locke adhered to the Experimental Philosophy, he was not averse to speculation about the corpuscular nature of matter. Anstey takes us into new terrain and new interpretations of Locke's thought in his explorations of his mercurialist transmutational chymistry, his theory of generation by seminal principles, and his conventionalism about species.

This book offers a reassessment of the political philosophy of the British Idealists, a group of once influential and now neglected nineteenth-century Hegelian philosophers, whose work has been much misunderstood. Peter Nicholson focuses on F. H. Bradley's idea of morality and moral philosophy; T. H. Green's theory of the Common Good, of the social nature of rights, of freedom, and of state interference; and Bernard Bosanquet's notorious theory of the General Will. By examining the arguments offered by the Idealists (...) and by their critics the author is able to penetrate the deep layers of hostile comment laid down by several generations of later writers and to show that these ideas, once properly understood, are not only defensible but interesting and important.

In at least some cases of justified perceptual belief, our perceptual experience itself, as opposed to beliefs about it, evidences and thereby justifies our belief. While the phenomenon is common, it is also mysterious. There are good reasons to think that perceptions cannot justify beliefs directly, and there is a significant challenge in explaining how they do. After explaining just how direct perceptual justification is mysterious, I considerMichael Huemers (Skepticism and the Veil of Perception, 2001) and Bill Brewers (Perception and (...) Reason, 1999) recent, but radically different, attempts to eliminate it. I argue that both are unsuccessful, though a consideration of their mistakes deepens our appreciation of the mystery.

This book presents and evaluates the late philosophy (Spätphilosophie) of F. W. J. Schelling (1775-1854) across a wide range of issues, ranging from relation between pure thinking and being, to the philosophy of mythology and religion, to the philosophy of history, to questions concerning the philosophy of nature and freedom. Simultaneously, it discusses Hegel's treatment of similar issues, and systematically compares the two thinkers. This is the first time, in an English-language publication, that these two major German Idealists have been (...) compared in such detail along such a broad front. The book begins with three chapters exploring the development of Schelling's thinking concerning transcendental philosophy, nature and teleology, human freedom, and the theory of history, from his earliest publications up to his middle years. Against this background, the book then presents Schelling's distinction between "positive" and "negative" philosophy, the defining mark of his late philosophy. It explores his theory of pure a priori thinking (negative philosophy), and his account of the transition from negative to positive philosophy. The major components of Schelling's positive philosophy, including his conception of "un-pre-thinkable being", and his theories of mythology and revelation, are then discussed. Throughout, a comparative assessment of Hegel's approach similar issues is sustained. Schelling emerges as a philosopher who traced his own highly distinctive path through the thicket of problems bequeathed by Kant, and whose systematic responses to these problems still merit serious consideration as alternatives to those of Hegel.

This is the first volume of a projected three-volume set on the subject of innateness. The extent to which the mind is innate is one of the central questions in the human sciences, with important implications for many surrounding debates. By bringing together the top nativist scholars in philosophy, psychology, and allied disciplines these volumes provide a comprehensive assessment of nativist thought and a definitive reference point for future nativist inquiry. The Innate Mind: Structure and Content, concerns the fundamental architecture (...) of the mind, addressing such question as: What capacities, processes, representations, biases, and connections are innate? How do these innate elements feed into a story about the development of our mature cognitive capacities, and which of them are shared with other members of the animal kingdom? The editors have provided an introduction giving some of the background to debates about innateness and introducing each of the subsequent essays, as well as a consolidated bibliography that will be a valuable reference resource for all those interested in this area. The volume will be of great importance to all researchers and students interested in the fundamental nature and powers of the human mind. Together, the three volumes in the series will provide the most intensive and richly cross-disciplinary investigation of nativism ever undertaken. They point the way toward a synthesis of nativist work that promises to provide a new understanding of our minds and their place in the natural order. (shrink)

In the mid-seventeenth century a movement of self-styled experimental philosophers emerged in Britain. Originating in the discipline of natural philosophy amongst Fellows of the fledgling Royal Society of London, it soon spread to medicine and by the eighteenth century had impacted moral and political philosophy and even aesthetics. Early modern experimental philosophers gave epistemic priority to observation and experiment over theorising and speculation. They decried the use of hypotheses and system-building without recourse to experiment and, in some quarters, developed a (...) philosophy of experiment. The movement spread to the Netherlands and France in the early eighteenth century and later impacted Germany. Its important role in early modern philosophy was subsequently eclipsed by the widespread adoption of the Kantian historiography of modern philosophy, which emphasised the distinction between rationalism and empiricism and had no place for the historical phenomenon of early modern experimental philosophy. The re-emergence of interest in early modern experimental philosophy roughly coincided with the development of contemporary x-phi and there are some important similarities between the two. (shrink)

Epistemic defeat is standardly understood in either evidentialist or responsibilist terms. The seminal treatment of defeat is an evidentialist one, due to John Pollock, who famously distinguishes between undercutting and rebutting defeaters. More recently, an orthogonal distinction due to Jennifer Lackey has become widely endorsed, between so-called doxastic (or psychological) and normative defeaters. We think that neither doxastic nor normative defeaters, as Lackey understands them, exist. Both of Lackey’s categories of defeat derive from implausible assumptions about epistemic responsibility. Although Pollock’s (...) evidentialist view is superior, the evidentialism per se can be purged from it, leaving a general structure of defeat that can be incorporated in a reliabilist theory that is neither evidentialist nor responsibilist in any way.

We propose a model of motivated skepticism that helps explain when and why citizens are biased information processors. Two experimental studies explore how citizens evaluate arguments about affirmative action and gun control, finding strong evidence of a prior attitude effect such that attitudinally congruent arguments are evaluated as stronger than attitudinally incongruent arguments. When reading pro and con arguments, participants (Ps) counterargue the contrary arguments and uncritically accept supporting arguments, evidence of a disconfirmation bias. We also find a confirmation bias—the (...) seeking out of confirmatory evidence—when Ps are free to self-select the source of the arguments they read. Both the confirmation and disconfirmation biases lead to attitude polarization—the strengthening of t2 over t1 attitudes—especially among those with the strongest priors and highest levels of political sophistication. We conclude with a discussion of the normative implications of these findings for rational behavior in a democracy. (shrink)
