Michael Bergmann claims that all versions of epistemic internalism face an irresolvable dilemma. We show that there are many plausible versions of internalism that falsify this claim. First, we demonstrate that there are versions of ‘‘weak awareness internalism’’ that, contra Bergmann, do not succumb to the ‘‘Subject’s Perspective Objection’’ horn of the dilemma. Second, we show that there are versions of ‘‘strong awareness internalism’’ that do not fall prey to the dilemma’s ‘‘vicious regress’’ horn. We note along the way that (...) these versions of internalism do not, in avoiding one horn of the dilemma, succumb to the dilemma’s other horn. The upshot is that internalists have many available strategies for avoiding dilemmatic defeat. (shrink)
In this paper, I develop, motivate and offer a qualified defense of a version of satisficing consequentialism (SC). I develop the view primarily in light of objections to other versions of SC recently posed by Ben Bradley. I motivate the view by showing that it (1) accommodates the intuitions apparently supporting those objections, (2) is supported by certain ‘common sense’ moral intuitions about specific cases, and (3) captures the central ideas expressed by satisficing consequentialists in the recent literature. Finally, I (...) offer a qualified defense of the view that consists in showing that it meets Bradley’s criteria for being a version of satisficing consequentialism that is ‘worth considering’. Specifically, it is a version of SC that solves certain problems for maximizing consequentialism and yet does not permit the gratuitous prevention of goodness. (shrink)
Self-regulated learning is critical for learning across tasks, domains, and contexts. Despite its importance, research shows that not all learners are equally skilled at accurately and dynamically monitoring and regulating their self-regulatory processes. Therefore, learning technologies, such as intelligent tutoring systems, have been designed to measure and foster SRL. This paper presents an overview of over 10 years of research on SRL with MetaTutor, a hypermedia-based ITS designed to scaffold college students’ SRL while they learn about the human circulatory system. (...) MetaTutor’s architecture and instructional features are designed based on models of SRL, empirical evidence on human and computerized tutoring principles of multimedia learning, Artificial Intelligence in educational systems for metacognition and SRL, and research on SRL from our team and that of other researchers. We present MetaTutor followed by a synthesis of key research findings on the effectiveness of various versions of the system on learning outcomes. First, we focus on findings from self-reports, learning outcomes, and multimodal data and their contributions to our understanding of SRL with an ITS. Second, we elaborate on the role of embedded pedagogical agents as external regulators designed to scaffold learners’ cognitive and metacognitive SRL strategy use. Third, we highlight and elaborate on the contributions of multimodal data in measuring and understanding the role of cognitive, affective, metacognitive, and motivational processes. Additionally, we unpack some of the challenges these data pose for designing real-time instructional interventions that scaffold SRL. Fourth, we present existing theoretical, methodological, and analytical challenges and briefly discuss lessons learned and open challenges. (shrink)
Winning essay of the American Society for Aesthetics' inaugural Peter Kivy Prize. Extends Kivy's notion of sonic picturing through engagement with recent work in philosophy of perception. Argues that sonic pictures are more widespread and more aesthetically and artistically important than even Kivy envisioned. Topics discussed include: the nature of sonic pictures; the nature of sounds; what we can (and more importantly, cannot) conclude from musical listening; sonic pictures in film; beatboxing as an art of sonic picturing; and cover songs (...) as sonic pictures. To be published in the Journal of Aesthetics and Art Criticism. (shrink)
Conversational interactions depend on partners making contingent responses. This experiment examined the responses of five chimpanzees, Washoe, Moja, Tatu, Dar and Loulis, to four conversational conditions. Following the chimpanzee’s request, a human interlocutor either: complied with the request, provided an unrequested item or activity, refused to comply or did not respond to the request. The chimpanzees’ responses were contingent on the conversational input of the interlocutor. When their requests were satisfied, the chimpanzees most often ceased signing. However, when their requests (...) were misunderstood, refused or not acknowledged, the chimpanzees repeated and revised. This pattern of responses is comparable to patterns of conversational responses in human children. Keywords: chimpanzees; American Sign Language; requests; pragmatics; conversation; gesture; communication; Pan troglodytes. (shrink)
The practice of Ontography deployed by OOO, clarified and expanded in this essay, produces a highly productive framework for analyzing Salvador Dalí’s ontological project between 1928 and 1935. Through the careful analysis of paintings and original texts from this period, we establish the antecedents for Dalí’s theorization of Surrealist objects in Cubism and Italian Metaphysical art, which we collectively refer to as ‘Ontographic art,’ drawing parallels with the tenets of Graham Harman’s and Ian Bogost’s object-oriented philosophical programmes. We respond to (...) the question raised by Roger Rothman concerning Object-Oriented Idealism in Dalí’s work by showing pivotal changes to Dalí’s ontological outlook, from Idealism to Realism, across the aforementioned period, positing the Ontographic intentionality of Dalí’s ontological project in Surrealist art.

In 1934, Oscar Reutersvärd drew what is generally acknowledged to be the first impossible triangle. Over the course of his lifetime, Reutersvärd created thousands of impossible figures, three of which would later adorn a series of Swedish postage stamps. But despite his enormous, inventive output, Reutersvärd is not widely known. Instead, impossible figures are popularly associated with M. C. Escher—three of whose more famous works include impossible figures—and the mathematical physicist Roger Penrose, who published the first academic article about impossible (...) figures in 1958 after independently discovering the impossible triangle. For Escher and Penrose, however, impossible figures were merely a passing interest. And while Penrose was concerned primarily with the mathematics of impossible figures and Escher integrated them into familiar human scenes, Reutersvärd’s abstract, minimalistic renderings express a fascination with the figures themselves. Free of adornment, they attract and command the eye, and exhibit a strange and peculiar beauty. -/- In this chapter, I investigate why we find impossible figures so visually compelling. In other words, my concern here is the specifically aesthetic appeal of impossible figures. Mathematicians and logicians have studied them for their mathematical and logical properties (Mortensen 2010), psychologists for what they reveal about the visual system (Gregory 1997, chap. 10), and philosophers in part for what they tell us about the limits of the imagination (Elpidorou 2016, 11), but we value them mainly as things to look at. This is what I want to understand. -/- I will work in three stages, using three methods. First, I will define the domain of investigation. What exactly is an impossible figure? Answering this question requires a form of conceptual analysis and raises a variety of interesting philosophical issues. Second, I will ask about the experience of looking at impossible figures. Here I will proceed by introspection—a first-person study of my own experience. Finally, I will appeal to results from experimental psychology to develop an empirically-grounded hypothesis about the visual appeal of impossible figures. If things go well, we will learn something not only about impossible figures, but about ourselves, and how and why we look at visual art in general. (shrink)
In a recent conference volume, American philosopher Michael Sandel engages the Confucian tradition in the search for alternatives to what Sandel calls the “unencumbered self,” the unattached liberal subject as detailed in the philosophy of John Rawls. Responding to Sandel, American Confucianist Roger Ames draws on a lifetime of comparative thought to advance the Pragmatism of John Dewey as a way to interrogate Western philosophy in general, arguing that “humane becomings,” a view of the human person facilitated, Ames writes, by (...) Deweyan Pragmatism, are the Confucian ideal and the key to recovering a holistic anthropology within the Western tradition. In this essay, I intervene in the Ames-Sandel debate to argue that Charles Peirce, and not John Dewey, is the best American Pragmatist for bridging the divide between the Confucian and Rawlsian views of the human person. Peirce’s emphasis on love as true intersubjectivity and on communication as the exchange of real meaning is, I argue, the key to unlocking the Confucian ideal to the West. (shrink)

Virtue ethics is now well established as a substantive, independent normative theory. It was not always so. The revival of virtue ethics was initially spurred by influential criticisms of other normative theories, especially those made by Elizabeth Anscombe, Philippa Foot, John McDowell, Alasdair MacIntyre, and Bernard Williams. 1 Because of this heritage, virtue ethics is often associated with anti-theory movements in ethics and more recently, moral particularism. There are, however, quite a few different approaches to ethics that can reasonably claim (...) to be versions of virtue ethics. The predominant strand of virtue ethics is broadly Aristotelian, although some accounts bear little resemblance to Aristotle's. In its most general form, virtue ethics is compatible with a wide range of meta-ethical and normative commitments. This diversity makes it difficult to compare virtue ethics as such with other normative theories. It can also be a challenge to see just what the various versions of virtue ethics have in common with each other. Three major types of virtue ethics are represented in the books by Rosalind Hursthouse, Michael Slote, and Christine Swanton, recommended in the following section. Each of these book sets forward a considerably self-standing form of virtue ethics. The authors differ on central issues such as the relationship between virtue and flourishing and the link between virtuous agents and right or virtuous actions. Unlike Swanton and Slote, Hursthouse defends a version of ethical naturalism that has affinities with theories recently defended by Philippa Foot and Alasdair MacIntyre. 2 Slote's theory is agent-based, meaning that his account derives judgments about the moral status of actions from moral features of agents. Hursthouse and Swanton defend theories according to which the moral status of an action depends on its broader relationship to human flourishing (Hursthouse) or whether it hits the target of a virtue (Swanton). Although these three books presently form the core of contemporary virtue ethics, there are other approaches that might reasonably be described as versions of virtue ethics, such as those presented by Julia Driver, Linda Zagzebski, and Robert Adams. 3 There are also, of course, a large number of articles in which authors defend or criticize tenets that are central to most versions of virtue ethics. Some recent articles on especially important topics are listed in the following section. Current 'hot topics' in virtue ethics include whether its account of right action is adequate and whether virtue ethics is at odds with empirical psychology. Articles on these debates and others are listed in the following section. Author Recommends: Books These three books are foundational works in contemporary virtue ethics, and represent quite different approaches to virtue ethics. For each book, I have also listed an article by the same author in which he or she articulates some similar themes. Those pressed for time or space on a syllabus might start by examining those articles. 1. Hursthouse, Rosalind. On Virtue Ethics. Oxford: Oxford University Press, 1999. Hursthouse defends a eudaimonistic version of virtue ethics with Aristotelian affinities. *See also Hursthouse, Rosalind. 'Normative Virtue Ethics.' How Should One Live? Ed. Roger Crisp. Oxford: Clarendon Press, 1996. 19–36. 2. Slote, Michael. Morals from Motives. Oxford: Oxford University Press, 2001. Slote defends a version of virtue ethics based on evaluations of motives, drawing on historical figures like Martineau, Hutcheson, and Hume. Note that this book represents a fairly significant departure from his first book in virtue ethics, From Morality to Virtue (New York: Oxford, 1992). *See also Slote, Michael. 'Agent-Based Virtue Ethics.' Virtue Ethics . Ed. Roger Crisp and Michael Slote. Oxford: Oxford University Press, 1997. 3. Swanton, Christine. Virtue Ethics: A Pluralistic View. Oxford: Oxford University Press, 2003. Swanton defends a pluralistic, non-eudaimonistic version of virtue ethics that draws on influences ranging from Aristotle to Nietzsche to contemporary psychoanalytic theory. *See also Swanton, Christine. 'A Virtue Ethical Account of Right Action.' Ethics 112 (2001): 32–52. Articles The following is a selection of articles that address some of the central and controversial topics within virtue ethics. 1. Annas, Julia. 'Being Virtuous and Doing the Right Thing.' Proceedings and Addresses of the American Philosophical Association 78.2 (2004): 61–75. This article addresses the problem of action guidance and the role that an account of right action should play in virtue ethics. 2. Conly, Sarah. 'Flourishing and the Failure of the Ethics of Virtue.' Midwest Studies in Philosophy Vol. XIII, Ethical Theory: Character and Virtue . Eds. P. French et al. South Bend: University of Notre Dame Press, 1988. 83–96. This article articulates the central problems faced by versions of virtue ethics that rely on a conception of human flourishing. 3. Das, Ramon. 'Virtue Ethics and Right Action.' Australasian Journal of Philosophy 81 (2003): 324–39. This article raises objections about insularity and circularity to accounts of right action presented by Hursthouse, Slote, and Swanton. 4. Doris, John M. 'Persons, Situations, and Virtue Ethics.' Nous 32 (1998): 504–30. This article argues that situationist psychology undermines the concept of a character trait on which virtue ethicists rely. An expanded version of this criticism can be found in Doris, Lack of Character, Cambridge: Cambridge University Press, 2002. 5. Hursthouse, Rosalind. 'Virtue Theory and Abortion.' Philosophy and Public Affairs 20.3 (1991): 223–46. This article argues that virtue ethics is capable of providing action guidance in the difficult problem of abortion. 6. Johnson, Robert N. 'Virtue and Right.' Ethics 113 (2003): 810–34. This article raises several objections against the accounts of right action in virtue ethics, one of which is that they cannot make sense of the rightness of self-improving actions. The criticism is directly primarily at Hursthouse's theory, but Swanton and Slote are discussed as well. 7. Kamtekar, Rachana. 'Situationism and Virtue Ethics on the Content of Our Character.' Ethics 114 (2004): 458–91. This article argues that situationist critiques of virtue ethics rely on a mistaken understanding of virtuous character. 8. Kawall, Jason. 'Virtue Theory and Ideal Observers.' Philosophical Studies 109 (2002): 197– 222. This article argues for an ideal observer-style account of right action in virtue ethics. 9. Nussbaum, Martha. 'Non-Relative Virtues: An Aristotelian Approach.' Midwest Studies in Philosophy, Vol. XIII, Ethical Theory: Character and Virtue . Ed. P. French et al. South Bend: University of Notre Dame Press, 1988. 32–53. This article presents a view of the virtues on which the virtues are excellences in spheres of activity. Although the spheres are common to all humans, the manifestation of excellence in a given sphere is subject to cultural variation. 10. Sreenivasan, Gopal. 'Errors about Errors: Virtue Theory and Trait Attribution.' Mind 111 (2002): 47–68. This article addresses the situationist critique of character traits by arguing that virtue ethics does not depend on the concept of a character trait as Doris and others understand it. 11. Stangl, Rebecca. 'A Dilemma for Particularist Virtue Ethics.' Philosophical Quarterly 58 (2008): 665–78. This article addresses the relationship between virtue ethics and radical moral particularism, arguing that the latter may have undesirable consequences for virtue ethicists unless they accept the unity of the virtues. 12. Stohr, Karen. 'Contemporary Virtue Ethics.' Philosophy Compass 1.1 (January 2006): 22–7. This article provides an overview and analysis of contemporary virtue ethics. It includes discussion of main problems and challenges for the future. 13. Stohr, Karen. 'Moral Cacophony: When Continence is a Virtue.' Journal of Ethics 7 (2003): 339–63. This article raises problems for the commonly accepted distinction between virtue and continence, arguing that the mixed emotions normally associated with continence are sometimes characteristic of virtue instead. 14. van Zyl, Liezl. 'Agent-Based Virtue Ethics and the Problem of Action Guidance.' Journal of Moral Philosophy 6 (2009): 50–69. This article defends agent-based virtue ethics against objections that it cannot distinguish agent-appraisal from act-appraisal and that it cannot provide adequate action guidance. Anthologies 1. Crisp, Roger, ed. How Should One Live? Essays on the Virtues. Oxford: Clarendon Press, 1996. This is one of the first virtue ethics anthologies published, and so reflects a correspondingly earlier picture of the field. The essays, however, are important and interesting in their own right, and cover a broad array of topics. 2. Crisp, Roger and Michael Slote, eds. Virtue Ethics . Oxford: Oxford University Press, 1997. This anthology was published over a decade ago and does not capture recent developments in the field. It is, however, an admirably thorough collection of the most influential essays from the early days of virtue ethics, both promoting and criticizing it. 3. Darwall, Stephen, ed. Virtue Ethics. Oxford: Blackwell, 2003. This anthology is distinctive in that it includes material from Aristotle, Hutcheson, and Hume, along with some central contemporary sources. 4. Walker, Rebecca L. and Philip J. Ivanhoe, eds. Working Virtue. Oxford: Oxford University Press, 2007. This recent anthology focuses on applied virtue ethics and has an excellent selection of essays by influential thinkers on topics including the environment, business, medicine, war, and poverty.

Historically, philosophers of biology have tended to sidestep the problem of development by focusing primarily on evolutionary biology and, more recently, on molecular biology and genetics. Quite often too, development has been misunderstood as simply, or even primarily, a matter of gene activation and regulation. Nowadays a growing number of philosophers of science are focusing their analyses on the complexities of development, and in Embryology, Epigenesis and Evolution Jason Scott Robert explores the nature of development against current trends in (...) biological theory and practice and looks at the interrelations between development and evolution , an area of resurgent biological interest. Clearly written, this book should be of interest to students and professionals in the philosophy of science and the philosophy of biology. (shrink)
Roger North's The Musicall Grammarian 1728 is a treatise on musical eloquence in all its branches. Of its five parts, I and II, on the orthoepy, orthography and syntax of music, constitute a grammar; III and IV, on the arts of invention and communication, form a rhetoric; and V, on etymology, consists of a history. Two substantial chapters of commentary introduce the text, which is edited here for the first time in its entirety: Jamie Kassler places his treatise within the (...) broader context not only of North's musical and non-musical writings but also their relation to the intellectual ferment of the seventeenth and eighteenth centuries and Mary Chan describes physical and textual aspects of the treatise as evidence for North's processes of thinking about musical thinking.

Los teóricos de la democracia dejaron de lado la pregunta de quién legalmente forma parte del "pueblo" autorizado, pregunta que atraviesa a todas las teoría de la democracia y continuamente vivifica la práctica democrática. Determinar quién constituye el pueblo es un dilema inabordable e incluso imposible de responder democráticamente; no es una pregunta que el pueblo mismo pueda decidir procedimentalmente porque la propia premisa subvierte las premisas de su resolución. Esta paradoja del mandato popular revela que el pueblo para ser (...) mejor comprendido como una demanda política, como un proceso de subjetivación, surge y se desarrolla en distintos contextos democráticos. En Estados Unidos el disputado poder para hablar en beneficio del pueblo deriva de un excedente constitutivo heredado de la era revolucionaria, a partir del hecho de que desde la Revolución el pueblo ha sido por vez primera encarnado por la representación y como exceso de cualquier forma de representación. La autoridad posrevolucionaria del vox populi deriva de esa continuamente reiterada pero nunca realizada referencia a la soberanía del pueblo a partir de la representación, legitimidad a partir de la ley, espíritu a partir de la letra, la palabra a través de la palabra. Este ensayo examina la emergencia histórica de este exceso de democracia en el período revolucionario, y cómo este habilita a una subsecuente historia de "momentos constituyentes", momentos cuando subautorizados -radicales, entidades autocreadas-, se apoderan del manto de la autoridad, cambiando las reglas de la autoridad en ese proceso. Estos pequeños dramas de reclamos de autoridad política para hablar en nombre del pueblo son felices, aun cuando explícitamente rompan con los procedimientos o reglas estatuidas para representar la voz popular. -/- Momentos constituyentes: paradojas y poder popular en los Estados Unidos de América posrevolucionarios [traducción], Revista Argentina de Ciencia Política, N°15, EUDEBA, Buenos Aires, Octubre 2012, pp. 49-74.

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. The first volume covers the beginnings of a career that is ground-breaking from the outset. Inspired by courses given by Dirac and Bondi, much of the early published (...) work involves linking general relativity with tensor systems. Among his early works is the seminal 1955 paper, 'A Generalized Inverse for Matrices', his previously unpublished PhD and St John's College Fellowship theses, and from 1967, his Adam's Prize-winning essay on the structure of space-time. Add to this his 1965 paper, 'Gravitational collapse and space-time singularities', and the 1967 paper that introduced a remarkable new theory, 'Twistor algebra', and this becomes a truly stellar procession of works on mathematics and cosmology.

Professor Sir Roger Penrose is one of the truly original thinkers of our time. He has made several remarkable contributions to science, from quantum physics and theories of human consciousness to relativity theory and observations on the structure of the universe. Unusually for a scientist, some of his ideas have crossed over into the public arena. Now his work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the (...) first time and arranged chronologically over six volumes, each with an introduction from the author.

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. Many important realizations concerning twistor theory occurred during the short period of this third volume, providing a new perspective on the way that mathematical features of the complex (...) geometry of twistor theory relate to actual physical fields. Following on from the nonlinear graviton construction, a twistor construction was found for (anti-)self-dual electromagnetism allowing the general (anti-)self-dual Yang-Mills field to be obtained. It became clear that some features of twistor contour integrals could be understood in terms of holomorphic sheaf cohomology. During this period, the Oxford research group founded the informal publication, Twistor Newsletter. This volume also contains the influential Weyl curvature hypothesis and new forms of Penrose tiles.

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. Among the new developments that occurred during this period was the introduction of a particular notion of 'quasi-local mass-momentum and angular momentum', the topic of Penrose's Royal Society (...) paper. Many encouraging results were initially obtained but, later, difficulties began to emerge and remain today. Also, an extensive paper (with Eastwood and Wells) gives a thorough account of the relation between twistor cohomology and massless fields. This volume witnesses Penrose's increasing conviction that the puzzling issue of quantum measurement could only be resolved by the appropriate unification of quantum mechanics with general relativity, where that union must involve an actual change in the rules of quantum mechanics as well as in space-time structure. Penrose's first incursions into a possible relation between consciousness and quantum state reduction are also covered here. (shrink)

Where relevant, individual papers also come with specific introductions or notes. Publication of The Emperor's New Mind (OUP 1989) had caused considerable debate and Penrose's responses are included in this volume. Arising from this came the idea that large-scale (...) quantum coherence might exist within the conscious brain, and actual conscious experience would be associated with a reduction of the quantum state. Within this collection, Penrose also proposes that a twistor might usefully be regarded as a source (or 'charge') for a massless field of spin 3/2, suggesting that the twistor space for a Ricci-flat space-time might actually be the space of such possible sources. Towards the end of the volume, Penrose begins to develop a quite different approach to incorporating full general relativity into twistor theory. This period also sees the origin of the Diósi-Penrose proposal. (shrink)

Where relevant, individual papers also come with specific introductions or notes. This sixth volume describes an actual experiment to measure the length of time that a quantum superposition might last (developing the Diósi-Penrose proposal). It also discusses the significant (...) progress made in relation to incorporating the 'googly' information for a gravitational field into the structure of a curved twistor space. Penrose also covers such things as the geometry of light rays in relation to twistor-space structures, the utility of complex numbers in drawing three-dimensional shapes, and the geometrical representation of different types of musical scales. The turn of the millennium was also an opportunity to reflect on progress in many areas up until that point. (shrink)

Where relevant, individual papers also come with specific introductions or notes. Developing ideas sketched in the first volume, twistor theory is now applied to genuine issues of physics, and there are the beginnings of twistor diagram theory (an analogue (...) of Feynman Diagrams).

Jason Stanley presents a startling and provocative claim about knowledge: that whether or not someone knows a proposition at a given time is in part determined by his or her practical interests, i.e. by how much is at stake for that person at that time. In defending this thesis, Stanley introduces readers to a number of strategies for resolving philosophical paradox, making the book essential not just for specialists in epistemology but for all philosophers interested in philosophical methodology. Since (...) a number of his strategies appeal to linguistic evidence, it will be of great interest to linguists as well. (shrink)
Precursors. 2.1 Introduction Thus far I have presented an approach to the semantics of plurals in the form of two rather similar grammars for a fragment of English. And I have given a few examples of the kinds of things one can say within this ...
Jason Stanley's "Knowledge and Practical Interests" is a brilliant book, combining insights about knowledge with a careful examination of how recent views in epistemology fit with the best of recent linguistic semantics. Although I am largely convinced by Stanley's objections to epistemic contextualism, I will try in what follows to formulate a version that might have some prospect of escaping his powerful critique.
Book Description: First published in 1980, this contribution to political thought is a statement of the traditional conservative position. Roger Scruton challenges those who would regard themselves as conservatives, and also their opponents. Conservatism, he argues, has little in common with liberalism, and is only tenuously related to the market economy, to monetarism, to free enterprise or to capitalism. It involves neither hostility towards the state, nor the desire to limit the state's obligation towards the citizen. Its conceptions of society, (...) law and citizenship regard the individual not as the premise but as the conclusion of politics. At the same time it is fundamentally opposed to the ethic of social justice, to equality of station, opportunity, income and achievement, and to the attempt to bring major institutions of society such as schools and universities under government control.

The earliest Analects yet discovered, this work provides us with a new perspective on the central canonical text that has defined Chinese culture--and clearly illuminates the spirit and values of Confucius.
The categories of reason and faith are often contrasted. When reason gives out, we are told that we have to rely on faith. Such exhortations are made particularly in the context of religion. When for instance, we face some personal tragedy which may well seem inexplicable, we are told that faith can help us through it. Very often faith is referred to in a vacuum. Presumably faith in God is usually meant, but all too often God drops out of the (...) picture, and it seems that all we need is faith, not faith in anything or anyone, but just faith. We are thus encouraged to add what seems to be a magic ingredient to our lives, which can transform everything. Perhaps at the back of such thinking lies some Calvinist notion of the corrupt character of human reason. As a result it may seem that we cannot rely on our judgment, which is the product of the fallen and sinful nature of humanity. Instead we must depend on ‘faith’ which may, or may not, be given us by the grace of God. (shrink)
Roger Ariew presents a new account of Descartes as a philosopher who sought to engage his contemporaries and society. He argues that the Principles of Philosophy was written to rival Scholastic textbooks, and considers Descartes' enterprise in contrast to the tradition it was designed to replace and in relation to the works of the first Cartesians.
Speaking is so closely associated with making noises that such descriptions as ‘silent soliloquy’ and ‘soundless monologue’ have an air of paradox. Yet people frequently say things to themselves in such a way that not even a close observer has any reason to think they have done so. It is therefore tempting to suppose that on such occasions a sequence of surrogate speech sounds is produced in the person's head which he alone hears or introaudits, as if what distinguishes silent (...) inner speech from normal speech is that the word substitutes are conveniently hidden from all save their producer.

He who has seen everything empty itself is close to knowing what everything is filled with. Emptiness is probably the most important philosophical and religious concept of Mahayana Buddhism. Its precise meaning has been explained differently by different schools and in different Buddhist cultures, but almost all Mahāyāna Buddhists would agree with the following characterization: Philosophically , emptiness is the term that describes the ultimate mode of existence of all phenomena, namely, as naturally ‘empty’ of enduring substance, or self-existence : (...) rather than being independently self-originated, phenomena are dependently originated from causes and conditions. Emptiness, thus, explains how it is that phenomena change and interact as they do, how it is that the world goes on as it does. Religiously , emptiness is the single principle whose direct comprehension is the basis of liberation from samsāra, and ignorance of which, embodied in self-gasping is the basis of continued rebirth – hence suffering – in samsāra.

Many philosophers believe that there is a fundamental distinction between knowing that something is the case and knowing how to do something. According to Gilbert Ryle, to whom the insight is credited, knowledge-how is an ability, which is in turn a complex of dispositions. Knowledge-that, on the other hand, is not an ability, or anything similar. Rather, knowledge-that is a relation between a thinker and a true proposition.
Most economists believe capitalism is a compromise with selfish human nature. As Adam Smith put it, "It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interest." Capitalism works better than socialism, according to this thinking, only because we are not kind and generous enough to make socialism work. If we were saints, we would be socialists. In Why Not Capitalism ?, Jason Brennan (...) attacks this widely held belief, arguing that capitalism would remain the best system even if we were morally perfect. Even in an ideal world, private property and free markets would be the best way to promote mutual cooperation, social justice, harmony, and prosperity. Socialists seek to capture the moral high ground by showing that ideal socialism is morally superior to realistic capitalism. But, Brennan responds, ideal capitalism is superior to ideal socialism, and so capitalism beats socialism at every level. Clearly, engagingly, and at times provocatively written, Why Not Capitalism? will cause readers of all political persuasions to re-evaluate where they stand vis-à-vis economic priorities and systems—as they exist now and as they might be improved in the future.
