Computational models will play an important role in our understanding of human higher‐order cognition. How can a model's contribution to this goal be evaluated? This article argues that three important aspects of a model of higher‐order cognition to evaluate are (a) its ability to reason, solve problems, converse, and learn as well as people do; (b) the breadth of situations in which it can do so; and (c) the parsimony of the mechanisms it posits. This article argues that fits of (...) models to quantitative experimental data, although valuable for other reasons, do not address these criteria. Further, using analogies with other sciences, the history of cognitive science, and examples from modern‐day research programs, this article identifies five activities that have been demonstrated to play an important role in our understanding of human higher‐order cognition. These include modeling within a cognitive architecture, conducting artificial intelligence research, measuring and expanding a model's ability, finding mappings between the structure of different domains, and attempting to explain multiple phenomena within a single model.

Ethical naturalism holds that ethical facts about such matters as good and bad, right and wrong, are part of a purely natural world — the world studied by the sciences. It is supported by the apparent reasonableness of many moral explanations. It has been thought to face an epistemological challenge because of the existence of an “is-ought gap”; it also faces metaphysical objections from philosophers who hold that ethical facts would have to be supernatural or “nonnatural,” sometimes on the grounds (...) that ethical thought has a practical role that no thought about purely natural facts could have. Its defenders have argued resourcefully against these challenges. (shrink)

In any society influenced by a plurality of cultures, there will be widespread, systematic differences about at least some important values, including moral values. Many of these differences look like deep disagreements, difficult to resolve objectively if that is possible at all. One common response to the suspicion that these disagreements are unsettleable has always been moral relativism. In the flurry of sympathetic treatments of this doctrine in the last two decades, attention has understandably focused on the simpler case in (...) which one fairly self-contained and culturally homogeneous society confronts, at least in thought, the values of another; but most have taken relativism to have implications within a single pluralistic society as well. I am not among the sympathizers. That is partly because I am more optimistic than many about how many moral disagreements can be settled, but I shall say little about that here. For, even on the assumption that many disputes are unsettleable, I continue to find relativism a theoretically puzzling reaction to the problem of moral disagreement, and a troubling one in practice, especially when the practice involves regular interaction among those who disagree. This essay attempts to explain why. (shrink)

Michael Smith’s moral problem is not about whether to betray one’s friends or one’s country. It is a metaethical problem about how to combine three tempting theses that look mutually inconsistent: moral cognitivism, appraiser internalism about moral judgments and motivation, and a “Humean” account of motivation. In Smith’s formulation, these become: 1. Moral judgements of the form, ‘It is right that I φ’ express a subject’s belief about an objective matter of fact, a fact about what it is right for (...) her to do. 2. [Necessarily] if someone judges that it is right that she φs, then, ceteris paribus, she is motivated to φ. 3. An agent is motivated to act in a certain way just in case she has an appropriate desire and a means-end belief, where belief and desire are, in Hume’s terms, distinct existences. As he notes, many metaethical positions can be classified by the way they seek to escape this apparent inconsistency: noncognitivists deny 1 to preserve 2 and 3, some ethical naturalists deny 2 to save 1 and 3, and some internalist cognitivists deny 3 and keep 1 and 2. Smith devotes a chapter to each of these responses and then defends his own view, which retains all three claims in a position advertised as not only consistent but realist, internalist, and, in a broad sense, naturalist.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 27, Number 1, April 2001, pp. 3-83 Moral Skepticism and Moral Naturalism in Hume's Treatise NICHOLAS L. STURGEON Section I I believe that David Hume's well-known remarks on is and ought in his Treatise of Human Nature (T 469-70)1 have been widely misunderstood, and that in consequence so has their relation to his apparent ethical naturalism and to his skepticism about the role of reason (...) in morality. My aim in this paper is to display their connection with these larger issues in Hume's work by placing them in a more illuminating light. Readers may wonder whether there is anything left to say about the passage containing these remarks; they may also share Barry Stroud's suspicion that the vast literature focused on this one paragraph has "given it an importance and point out of all proportion to its actual role in the text of the Treatise."2 But I have some new things to say. I agree, moreover, that many recent discussions, in projecting twentieth-century assumptions onto Hume's text, have accorded this passage the wrong sort of importance: that is part of what I want to correct. But getting clear about what Hume is saying here is, I shall argue, a way of moving familiar and obviously central questions about his views on morality into an unfamiliar but revealing focus. Hume's is-ought thesis is commonly, and I believe correctly, seen as an application of his more general skepticism about the capacity of reason to discover "moral distinctions." But that general skepticism is usually taken, in turn, to conflict with those many passages in which Hume Nicholas L. Sturgeon is Professor of Philosophy, Sage School of Philosophy, Cornell University, Ithaca, NY 14853-3201, USA. e-mail: [email protected] 4 Nicholas L. Sturgeon appears to say, in a reductive and naturalistic vein, that ascriptions of moral virtue and vice simply state certain empirical facts, facts about our own sentiments. My central thesis, however, is that Hume's view that there is a logical gap between is and ought is not merely consistent with his reductive naturalism, but actually depends on it. It is precisely because moral ascriptions state the facts that they do about our sentiments that no ought can be derived from an is and, a bit more generally, that reason is unable to discover moral distinctions. Hume's skepticism about reason in ethics depends, I shall argue, on his reductive ethical naturalism. This is not the usual understanding of Hume's views, and it will require careful explanation and defense. I shall proceed in several stages. My first step, in Section II, will be to argue that Hume's naturalism is at least consistent with his skepticism about reason, and in particular with his remarks about is and ought. I shall show this by focusing on a difficulty often taken to epitomize the conflict between these two strains in his thought: namely, that the paragraph containing these remarks (T 469-70: henceforth, the is-ought paragraph) and the one immediately preceding it (which I shall call the matter -of-fact paragraph (T 468-9)) appear, on their most natural readings, flatly to contradict one another.3 On the most common reading of the is-ought paragraph, it assumes the existence of two classes of statements, «-statements and oM^hr-statements, and declares that no member of the latter class can be derived entirely from members of the former. In the preceding paragraph, however, Hume appears in the guise of an ethical naturalist and subjectivist, and, if we take him at his word, simply equates a moral judgment with one asserting what he himself calls a "matter of fact," albeit a psychological fact about oneself: So that when you pronounce any action or character to be vicious, you mean nothing, but that from the constitution of your nature you have a feeling or sentiment of blame from the contemplation of it. (T 469) But, one supposes, if a moral assessment of an action or character is equivalent in meaning to a description of one's sentiments, then it can be derived from that description, and there...

This essay aims to identify a semiotic consciousness found in New England Transcendentalism, consisting of the worldview that signs are pervasively present throughout nature and society. It finds that this worldview exists as a historical strand of thought stretching through the 19th century and, ultimately, further beyond, thereby making up an early movement in American semiotics. In this context, I furthermore see Transcendentalist thought informing the backdrop of Charles Peirce’s groundbreaking theory of signs later in the century, especially his metaphysical (...) claims about a “universe... perfused with signs”1 (1906: EP 2.394). In order to bring into full view the presence of a semiotic consciousness in Transcendentalism, I first address the intellectual history and genealogical roots that helped shape the minds of the Transcendentalists. Relevant influences include those both local to New England and imported from abroad, in particular the theologies of Jonathan Edwards and of Emanuel Swedenborg. Next, I directly examine the ideas of the figurehead of the Transcendentalist movement, Ralph Waldo Emerson, together with his Concord peers, Amos Bronson Alcott and Henry David Thoreau. Taking them as my case studies, I track the different ways a like-minded interest in signs takes shape within their individual projects. Focus-ing on their descriptions of nature, we find it in their experiences of the natural environment, their understanding of phenomena as representational and poetic, and their belief in the dialogical sharing of ideas across minds and species. Along the way, I further work out some of the aspects of a general theory of signs identifi-able within the Transcendentalist perspective, as well as distinguish it from other theoretical alternatives. Ultimately, I contend that the Transcendentalists held a similar idea of nature existing as a sign representing deep and varied meanings. (shrink)

This is an introductory book that targets the reader who has the ambition to apply economic analysis but may be missing a technical introduction to its mathematical techniques or seeks a structured elaboration of its philosophical principles. The book juxtaposes economic analysis with moral philosophy, political theory, egalitarianism, and other methodological principles and then passes to the details of methods such as model-building, derivatives, differential equations, statistical tests, and the use of computer programs.

This book opens with a simple introduction to financial markets, attempting to understand the action and the players of Wall Street by comparing them to the action and the players of main street. Firstly, it explores the definition of a security by its function, the departure from the buyer beware environment of corporate law and the entrance into the seller disclose environment of securities law. Secondly, it shows that the cost of disclosure rules is justified by their capacity to combat (...) irrationalities, fads, and panics. The third section explains how the structure of class actions is designed to improve deterrence. Next it explores the economic harm from insider trading and how the law fights it. In sum, the book shows how all these parts of securities law serve the virtuous cycle from liquidity to accurate prices and more trading and how the great recession showed that our securities regulation reacted mostly adequately to the crisis.

By closely engaging an exceptionally wide breadth of primary material – one simply unseen in previous philosophical interpretations of Emerson – The Philosophy of Ralph Waldo Emerson brings to bear the weight of his published and unpublished corpus on the topics of metaphys...

In multiple autobiographical sketches, Charles S. Peirce identifies New England Transcendentalism as an essential part of his intellectual biography. A well-known instance is the passage opening "The Law of Mind" that identifies the setting of his childhood and early education within "the neighborhood of Concord": I may mention, for the benefit of those who are curious in studying mental biographies, that I was born and reared in the neighborhood of Concord,—I mean in Cambridge,—at the time when Emerson, Hedge, and their (...) friends were disseminating the ideas that they had caught from Schelling, and Schelling from Plotinus, from Boehm, or from God knows what minds stricken with the monstrous mysticism of the East....

travel, emerson often insisted, is only for the fool-hearted. He said it so many times in his popular essays and public lectures, he had actually gained a reputation for it. [It] is a fool's paradise. Our first journeys discover to us the indifference of places. At home I dream that at Naples, at Rome, I can be intoxicated with beauty, and lose my sadness. I pack my trunk, embrace my friends, embark on the sea, and at last wake up in (...) Naples, and there beside me is the stern fact, the sad self, unrelenting, identical, that I fled from. I seek the Vatican, and the palaces. I affect to be intoxicated with sights and suggestions, but I am not intoxicated. My giant goes with me wherever I go.... (shrink)

In 1887 the Open Court Publishing Company had its founding in a philosophy of monism. The company’s proprietor Edward C. Hegeler began the enterprise in an effort to promote his personal philosophic, religious, and moral ideas. He believed that these ideas could be conciliated with the growing scientific trends of the late nineteenth century, and that monism was the intellectual framework for doing so. Paul Carus, the editor of the journals The Open Court and The Monist, joined Hegeler as an (...) intellectual ally in this regard. For thirty years he openly defended the doctrines of monism in countless articles and books, successfully grounding the Open Court on this philosophy. This paper uncovers the historical development of the philosophical origin of the Open Court as it began with Hegeler’s personal religious motives, his ideological tension with the original editor Benjamin Underwood, and his embrace of the monistic writings of Paul Carus. It also examines Hegeler’s and Carus’s publications and personal letters from the 1880s and 1890s in order to determine the fundamental doctrines of their unique sense of monism. In Carus’s writings in particular is proposed a monism of causality that is compatible with a deterministic worldview and a unitary conception of the sciences. Also, both Carus and Hegeler propose a monistic ethics of meliorism that conceives the diverse periods of human history to be evolving toward the one final end of the moral improvement of humankind. While these are the positive doctrines that they accept, they further reject the antitheses of philosophical dualism and irreligious attitude of agnosticism of all varieties. (shrink)

Na história da filosofia americana, há um filão de pensamento sobre os signos na natureza. Animais, insetos, árvores, flores, o clima, paisagens e a noite estrelada são todos encontrados expressivos de diversos significados. Além disso, esses fenômenos naturais são considerados por pensadores, como Ralph Waldo Emerson e Charles S. Peirce, como dotados de um caráter representativo no seu núcleo ontológico. A minha apresentação baseia-se nesta tradição, explorando a semiose da natureza em toda a sua extensão e no que diz respeito (...) ao seu ser fundamental. O seu objetivo é desvendar alguns fundamentos metafísicos que apoiariam a semiose universal, bem como defender a primazia de uma dimensão estética no centro da atividade semiótica. (shrink)
