Recent debates over the rise of an American Empire have relied on analogies to past empires, from ancient Athens to modern Britain. Such historical analogies, while inexact and debatable, are a basic mode of understanding our relation to the past. This article explores the analogy of the United States to the Roman Empire. The figure of Rome is a contested legacy, as can be seen in the long-ago writings of Livy and Tacitus, in the developing ideal of Rome during the (...) Middle Ages, and in the works of modern scholars and poets living under Soviet domination in Poland. Tacitus tells us that the most profound symptoms of empire may be seen in the homeland. The debate over analogies for the American Empire is thus a debate over the ?state of America's soul.? (shrink)

Organizational virtue orientation (OVO), an organizational-level construct, refers to the integrated set of beliefs and values that support ethical character traits and virtuous behaviors. To advance the study of organizational virtue, we examine OVO in firms making their initial public offerings (IPOs), with respect to key external stakeholders that serve as financial intermediaries (i.e., venture capital firms and underwriting banks). Drawing on stakeholder and resource dependence theories, we argue that mutual interdependencies occur between financial intermediaries and IPO firms such that (...) venture capital firms’ ownership levels and underwriter reputation are positively associated with the selection of more virtuous IPO firms. We also argue for the moderating relationship of IPO firm age on these main relationships; since IPO firms have more history and information availability, less importance will be placed on OVO in the selection process. In support of our hypotheses, the results of this study suggest the organizational virtue of IPO firms influences the selection decisions of financial intermediaries by reflecting positively on these key stakeholders to improve legitimacy and reputation.

Mystical Theology and Platonism in the Time of Cusanus engages with the history of mystical theology and Neoplatonic philosophy through the lens of the 15th century philosopher and theologian, Nicholas of Cusa. The volume comprises nineteen essays that break down the barriers between medieval and Renaissance studies, reinterpreting Cusanus’ place in the history of thought by exploring the archive that informed his thinking, while also interrogating his works by exploring them from the standpoint of their later reception by modern philosophers (...) and theologians. The volume also offers tribute to the career of Donald F. Duclow, a leading scholar in the field of Cusanus studies in particular and of the history of mystical theology and Neoplatonic philosophy more generally. (shrink)

ABSTRACT:Despite extensive research on organizational virtue, our understanding about factors that promote virtue within organizations remains unclear. Drawing on upper echelon theory, we examine the relationship between five top management team characteristics and organizational virtue orientation —the integrated set of values and beliefs that support ethical traits and virtuous behaviors of an organization. Specifically, we utilize prospectuses of initial public offering firms and 10-K post-IPO filings to explore how TMT composition with respect to member age, tenure, education, functional background, and (...) gender influences OVO. Additionally, we examine the moderating effects of organizational size, and argue that the more expansive structures and processes associated with larger organizations diminish the main relationships. Our findings, using two sources of data, are consistent, but somewhat mixed in their support for our hypotheses. Overall, TMT characteristics do appear to influence OVO, but in more complex and counterintuitive ways than initially expected. (shrink)

In most decision-making situations, there is a plethora of information potentially available to people. Deciding what information to gather and what to ignore is no small feat. How do decision makers determine in what sequence to collect information and when to stop? In two experiments, we administered a version of the German cities task developed by Gigerenzer and Goldstein (1996), in which participants had to decide which of two cities had the larger population. Decision makers were not provided with the (...) names of the cities, but they were able to collect different kinds of cues for both response alternatives (e.g., “Does this city have a university?”) before making a decision. Our experiments differed in whether participants were free to determine the number of cues they examined. We demonstrate that a novel model, using hierarchical latent mixtures and Bayesian inference (Lee & Newell, 2011) provides a more complete description of the data from both experiments than simple conventional strategies, such as the take–the–best or the Weighted Additive heuristics.

Radical psychiatrists and others assert that mental illness is a myth. The opening and closing portions of the paper deal with the impact such argument has had in law and psychiatry. The body of the paper discusses the five versions of the myth argument prevalent in radical psychiatry: (A) that there is no such thing as mental illness; (B) that those called ?mentally ill? are really as rational as everyone else, only with different aims; that the only reasons anyone ever (...) thought differently was (C) because of unsophisticated category mistakes or (D) because of an adherence to the epistemology of a sick society; and (E) that the phrase ?mental illness? is used to mask value judgments about others? behavior in pseudo?scientific respectability. Reasons are given for rejecting each of these versions of the argument that mental illness is a myth. (shrink)

:This essay undertakes two tasks: first, to describe the differing mens rea requirements for accomplice liability of both Anglo-American common law and the American Law Institute's Model Penal Code; and second, to recommend how the mens rea requirements of both of these two sources of criminal law in America should be amended so as to satisfy the goals of clarity and consistency and so as to more closely conform the criminal law to the requirements of moral blameworthiness. Three "pure models" (...) of the mens rea requirements for complicity are distinguished, based on the three theories of liability conventionally distinguished in the general part of Anglo-American criminal law. One of these, the vicarious responsibility model, is put aside initially because of both its descriptive inaccuracy and its normative undesirability. The analysis proceeds using the other two models: that of the mens rea requirements for principal liability for completed crimes, and that of the mens rea requirements for attempt liability. Both the common law and the Model Penal Code are seen as complicated admixtures of these two models, the common law being too narrow in the scope of its threatened liability and the Model Penal Code being both too broad and too opaque in its demands for accomplice liability. The normative recommendation of the paper is to adopt the model for the mens rea of complicity that treats it as a form of principal liability, recognizing that the overbreadth of liability resulting from adoption of that model would have to be redressed by adopting a "shopkeeper's privilege" as an affirmative defense separate from any mens rea requirement.

The existence of objects external to the mind is a proof-condition for the type of object demonstration Moore provided in his famous lecture. Affirming the existence of objects external to the mind is just a way of saying that one person can show (present, demonstrate) something to another to prove it is so, to prove it exists, Demonstrations like that are conclusive and immune to scepticism.

Articles by two American mathematicians, E. V. Huntington and Oswald Veblen, are discussed as examples of a movement in foundational research in the period 1900-1930 called American postulate theory. This movement also included E. H. Moore, R. L. Moore, C. H. Langford, H. M. Sheffer, C. J. Keyser, and others.

In this essay, I want to take another look at the phenomenon of transparency and its relevance to qualia realism and representationalism. I don’t suppose that what I have to say will cause those who disagree with me to change their minds, but I hope not only to clarify my position and that of others who are on my side of the debate but also to respond to various criticisms and objections that have arisen over the last 10–15 years or (...) so.The transparency thesisI begin with four quotations, two from G. E. Moore, one from Gilbert Harman, and one from an earlier paper of mine:…that which makes the sensation of blue a mental fact seems to escape us; it seems, if I may use a metaphor, to be transparent — we look through it and see nothing but the blue… (Moore 1903, p. 446).When we try to introspect the sensation of blue, all we can see is the blue: the other element is as if it were diaphanous (Moore 1903, p. 450).When Eloise sees a tree before her, the colors she experiences are all experien.

One afternoon in 1939, G. E. Moore held up his hands. He proceeded to make a certain gesture, first with his right hand and next with his left, while uttering the words, “Here is one hand and here is another.” Moore famously claimed to have thereby proved the existence of external things.

This paper argues that to account for group speech acts, we should adopt a representationalist account of mode / force. Individual and collective subjects do not only represent what they e.g. assert or order. By asserting or ordering they also indicate their theoretical or practical positions towards what they assert or order. The ‘Frege point’ cannot establish the received dichotomy of force and propositional content. On the contrary, only the representationalist account allows a satisfactory response to it. It also allows (...) us to give a more satisfactory analysis of the speech act of inviting a joint commitment and to answer two important questions Bernhard Schmid has raised about group speech acts, namely whether there are 1st person plural forms of Moore’s paradox and of 1st person authority.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

In a series of articles Christopher Cowie has provided what he calls a ‘Master Argument’ against the Companions in Guilt (CG) defence of moral objectivity. In what follows I defend the CG strategy against Cowie. I show, firstly, that epistemic judgements are relevantly similar to moral judgements, and secondly, that it is not possible coherently to deny the existence of irreducible and categorically normative epistemic reasons. My argument for the second of these claims exploits an analogy between the thesis that (...) epistemic norms are non-categorical and G.E. Moore’s paradox concerning first personal belief ascriptions. I argue that the absurdity of the assertion “I have evidence that p but no reason to believe it” shows that the norms of belief are categorical. I then consider the counter-argument that this categoricity is a ‘conceptual’ rather than an ‘objective’ requirement. By drawing on the work of Hilary Putnam and Charles Travis, I show that this counter-argument is unsuccessful. Putnam is one of the original proponents of the Companions in Guilt strategy. Thus, by supporting the CG argument through appeal to other Putnamian theses, I show that its insights can only fully be appreciated in the context of broader metaphysical and semantic lessons.

Moore’s paradox supports the principle of “metacoherence”, i.e., that if one categorically believes that P, one is committed to accepting that one knows that P. The principle raises puzzles about how, when one has justification for P, one also has justification for the claim that one knows P. I reject a skeptical answer as well as a bootstrapping answer, and I suggest that we typically have independent justification for the claim that we know P.

The concept of intrinsic value has enjoyed a long, rich history. From the time of the ancient Greeks to the present day, philosophers have placed it at the foundation of much of their theorizing. This is especially true of G.E. Moore, who made it the cornerstone of his Principia Ethica. Yet this venerable concept has recently come under serious, sustained attack. My aim in this paper is to show that this attack has been unsuccessful.When Principia Ethica appeared, its impact (...) on the philosophical community was immediate and profound. Of course, much of what Moore had to say was, and continues to be, strongly disputed. The view that goodness is a simple nonnatural property has been criticized by many people and in many ways. Some have argued that goodness is an analyzable property. Others have argued that it is a natural property. Still others have argued, more radically, that goodness is not a property at all. But none of these critics has rejected the very idea of goodness. None of them, that is, has contended that to say of something that it is good is to speak nonsense. (shrink)

Many philosophers have endorsed G. E. Moore’s principle of organic unities – according to which the value of a whole must not be assumed to be the same as the sum of the values of its parts – claiming this principle to be of fundamental importance to ethics. In this paper, I cast doubt on the principle. In Section 1, I provide a provisional reformulation of the principle of organic unities and contrast such unities with mere sums of value. (...) In Section 2, I do some groundwork in order to arrive at an account of the part–whole relation with which the principle of organic unities is concerned. In so doing, I provide some further reformulations of that principle. In Section 3, I discuss the isolation method that Moore proposes for determining the value of something, and then, in Section 4, I begin an extended discussion of a particular example of an alleged organic unity, namely, Schadenfreude. I explain why some philosophers claim that such pleasure constitutes an organic unity, but I also present reasons for denying this claim. In Section 5, I pursue one of these reasons in particular, a reason that appeals to the concept of what I call evaluative inadequacy, and, in Section 6, I seek to motivate this appeal by drawing on the relation between value and fitting attitudes. In so doing, I provide still further reformulations of the principle of organic unities. In Section 7, I entertain objections to my account of Schadenfreude, one of which requires one final reformulation of the principle of organic unities, and then, in Section 8, I discuss the more general objection that, even if my reasons for denying that Schadenfreude constitutes an organic unity are cogent, these reasons do not extend to other alleged organic unities, such as the related phenomenon of Mitleid. In the final section, I address the significance of the debate about whether the principle of organic unities is true. (shrink)

There may be as much philosophical controversy about how to distinguish naturalism from non-naturalism as there is about which view is correct. In spite of this widespread disagreement about the content of naturalism and non-naturalism there is considerable agreement about the status of certain historically influential philosophical accounts as non-naturalist. In particular, there is widespread agreement that G.E. Moore's account of goodness in.

RECENT STUDIES IN NORMATIVE ETHICS have concentrated on act evaluations, neglecting, almost ignoring, agent evaluations. A partial explanation of this defect is found in two related ones: the neglect of act evaluations other than the obligation notions, and the failure to do justice even to them. In each case, neglecting the "other" concepts is implicated in serious misunderstandings of what is considered—or more accurately, what is over-considered. Take, for example, the view that it is obligatory to obtain for oneself the (...) greatest good one can, e.g., pleasure. Even a cursory study of prudence and other primarily self-regarding notions could have saved Moore, Ross, Ewing, and many others from holding or committing themselves to this silly view. (shrink)

Sextus Empiricus offers an underappreciated and under-discussed version of dream-based skepticism. Most philosophers interested in dreams and skepticism focus on the question of how you know you are not currently dreaming. Sextus points out that our waking experiences and dreams often conflict. And, the challenge goes, what reason do you have to trust the one over the other? This question presupposes that dreams and waking experiences are distinguishable. Thus the kinds of responses typically offered against dream-based skepticism do not apply. (...) And if we accept an idea upheld by one camp in the contemporary debate over the epistemology of disagreement, Sextus’ challenge is difficult to answer. A G.E. Moore-inspired response to the problem is also proposed and explored. It is argued that Sextus’ version of the problem reveals a certain limitation in that sort of approach to skeptical problems.

Describes a Platonic personal spirituality based on reason that is readily accessible to people today. Michael LaFargue presents an important and accessible aspect of Plato’s legacy largely overlooked today: a variety of personal spirituality based on reason and centered on virtue. Plato’s Virtue-Forms are transcendent in their goodness, ideals that Platonists can use to improve character and become like God so far as is humanly possible. LaFargue constructs a model of inductive Socratic reasoning capable of acquiring knowledge of these (...) perfect Virtue-Forms, then scales back claims about these Forms to what can be supported by this kind of reasoning. This is a critical theory, but also a pluralistic one that accommodates modern cultural diversity. A how-to chapter provides detailed descriptions of the rules of Socratic reasoning basic to this spirituality, which any interested individual can practice today. LaFargue supports his interpretation by a close reading of the Greek text of key passages in Plato’s dialogues. The work also undertakes a broader philosophical consideration, discussing the philosophical foundations proposed for this Platonism in relation to the thought of G. E. Moore, Ludwig Wittgenstein, Martin Heidegger, Friedrich Nietzsche, and Richard Rorty. (shrink)

The so-called problem of arguing “from what is to what ought to be” was popularized by G.E. Moore in Principia Ethica (1903), and has received much attention from modern philosophers. I would like to argue that this apparent problem rests on a false dichotomy between our knowing and our doing.

This paper deals with the ‚description-thesis‘ (R. Schreiber 1962) according to which normative or prescriptive legal statements are reducible to, or translatable into, descriptive propositions. The arguments Schreiber produced in support of his thesis are briefly presented, followed by a discussion of the thesis against the background of Hume’s law and G. E. Moore’s open-question argument. In order to broaden the perspective, some other philosophical views are examined; emphasis is placed on how the is-ought relation was conceived, in conflicting (...) ways, by Hans Kelsen and Friedrich Müller respectively, as compared to the current state of discussion, and what are, according to Ernst Tugendhat and Christoph Möllers, the constituents of (social) norms. As a result, the paper suggests that the description-thesis can not be maintained in its entirety. A special version is presented which seems to respond to the criticism discussed while implying at least part of what Schreiber’s original version claimed. (shrink)

This article addresses and resolves an epistemological puzzle that has attracted much attention in the recent literature—namely, the puzzle arising from Moorean anti-sceptical reasoning and the phenomenon of transmission failure. The paper argues that an appealing account of Moorean reasoning can be given by distinguishing carefully between two subtly different ways of thinking about justification and evidence. Once the respective distinctions are in place we have a simple and straightforward way to model both the Wrightean position of transmission failure and (...) the Moorean position of dogmatism. The approach developed in this article is, accordingly, ecumenical in that it allows us to embrace two positions that are widely considered to be incompatible. The paper further argues that the Moorean Puzzle can be resolved by noting the relevant distinctions and our insensitivity towards them: once we carefully tease apart the different senses of ‘justified’ and ‘evidence’ involved, the bewilderment caused by Moore’s anti-sceptical strategy subsides.

G. E. Moore was a central figure in twentieth-century philosophy. Along with Russell and Wittgenstein, he pioneered analytic philosophy, and his Principia Ethica shaped the contours of twentieth-century ethics. Indeed, until the publication of Rawls's A Theory of Justice, no single book in moral philosophy was to equal Principia's influence. Unfortunately, however, Principia Ethica has so dominated critical discussions of Moore's work that even experts on his moral philosophy have tended to ignore his Ethics, which he published eight (...) years later. But Ethics is Moore's only other book on moral philosophy, and one of only a handful of post-Principia publications dealing with ethics. Its detailed discussions of utilitarianism, free will, and the objectivity of moral judgements find no real counterpart in Principia while its account of right and wrong and of the nature of intrinsic value deepen our understanding of his moral philosophy. The republication of Ethics thus rounds out our understanding of Moore's ethical thought. But the book's value goes beyond its historical or scholarly interest. A short but philosophically rich text, Ethics stands independent of Principia and repays careful study in its own right. By raising a number of fundamental questions in ethics, questions that remain live today, by proffering clear, credible, and often innovative answers to them, and by doing so with a philosophical skill that is still impressive, Moore's short book is a minor classic. Almost a century after its original publication, it still amply rewards those who read it.This new edition of Moore's Ethics includes his essay 'The Nature of Moral Philosophy' as well as editorial notes, an introduction, and a guide to further reading.

This collection of essays by one of the most prominent and internationally respected philosophers of action theory is concerned with deepening our understanding of the notion of intention. In Bratman's view, when we settle on a plan for action we are committing ourselves to future conduct in ways that help support important forms of coordination and organization both within the life of the agent and interpersonally. These essays enrich that account of commitment involved in intending, and explore its implications for (...) our understanding of temptation and self-control, shared intention and shared cooperative activity, and moral responsibility. The essays offer extensive discussions of related views by, among others, Donald Davidson, Hector-Neri Castañeda, Christine Korsgaard, Harry Frankfurt, and P. F. Strawson. This collection will be a valuable resource for a wide range of philosophers and their students. (shrink)

It is widely taken for granted that physical lines are real lines, i.e., that the arithmetical structure of the real numbers uniquely matches the geometrical structure of lines in space; and that other number systems, like Robinson's hyperreals, accordingly fail to fit the structure of space. Intuitive justifications for the consensus view are considered and rejected. Insofar as it is justified at all, the conviction that physical lines are real lines is a scientific hypothesis which we may one day reject. (...) /// En general se asume que las líneas físicas son líneas reales, esto es, que la estructura aritmética de los números reales corresponde de manera única a la estructura geométrica de líneas en el espacio, y que otros sistemas de números, como los hiperreales de Robinson, no logran corresponder a la estructura del espacio.
