During the academic year 1940-1941, several giants of analytic philosophy congregated at Harvard, holding regular private meetings, with Carnap, Tarski, and Quine. Carnap, Tarski, and Quine at Harvard allows the reader to act as a fly on the wall for their conversations. Carnap took detailed notes during his year at Harvard. This book includes both a German transcription of these shorthand notes and an English translation in the appendix section. Carnap’s notes cover a wide range of topics, but surprisingly, the (...) most prominent question is: If the number of physical items in the universe is finite, what form should scientific discourse take? This question is closely connected to an abiding philosophical problem: What is the relationship between the logico-mathematical realm and the material realm? Carnap, Tarski, and Quine’s attempts to answer this question involve issues central to philosophy today.This book focuses on three such issues: nominalism, the unity of science, and analyticity. In short, the book reconstructs the lines of argument represented in these Harvard discussions, discusses their historical significance (especially Quine’s break from Carnap), and relates them when possible to contemporary treatments of these issues.

Since anonymous agents can spread misinformation with impunity, many people advocate for greater accountability for internet speech. This paper provides a veritistic argument that accountability mechanisms can cause significant epistemic problems for internet encyclopedias and social media communities. I show that accountability mechanisms can undermine both the dissemination of true beliefs and the detection of error. Drawing on social psychology and behavioral economics, I suggest alternative mechanisms for increasing the trustworthiness of internet communication.

Modern scientific knowledge is increasingly collaborative. Much analysis in social epistemology models scientists as self-interested agents motivated by external inducements and sanctions. However, less research exists on the epistemic import of scientists’ moral concern for their colleagues. I argue that scientists’ trust in their colleagues’ moral motivations is a key component of the rationality of collaboration. On the prevailing account, trust is a matter of mere reliance on the self-interest of one’s colleagues. That is, scientists merely rely on external compulsion (...) to motivate self-interested colleagues to be trustworthy collaborators. I show that this self-interest account has significant limitations. First, it cannot fully account for trust by relatively powerless scientists. Second, reliance on self-interest can be self-defeating. For each limitation, I show that moral trust can bridge the gap—when members of the scientific community cannot rely on the self-interest of their colleagues, they rationally place trust in the moral motivations of their colleagues. Case studies of mid-twentieth-century industrial laboratories and exploitation of junior scientists show that such moral trust justifies collaboration when mere reliance on the self-interest of colleagues would be irrational. Thus, this paper provides a more complete and realistic account of the rationality of scientific collaboration. (shrink)

As a way to address both ominous and ordinary threats of artificial intelligence, researchers have started proposing ways to stop an AI system before it has a chance to escape outside control and cause harm. A so-called “big red button” would enable human operators to interrupt or divert a system while preventing the system from learning that such an intervention is a threat. Though an emergency button for AI seems to make intuitive sense, that approach ultimately concentrates on the point (...) when a system has already “gone rogue” and seeks to obstruct interference. A better approach would be to make ongoing self-evaluation and testing an integral part of a system’s operation, diagnose how the system is in error and to prevent chaos and risk before they start. In this paper, we describe the demands that recent big red button proposals have not addressed, and we offer a preliminary model of an approach that could better meet them. We argue for an ethical core that consists of a scenario-generation mechanism and a simulation environment that are used to test a system’s decisions in simulated worlds, rather than the real world. This EC would be kept opaque to the system itself: through careful design of memory and the character of the scenario, the system’s algorithms would be prevented from learning about its operation and its function, and ultimately its presence. By monitoring and checking for deviant behavior, we conclude, a continual testing approach will be far more effective, responsive, and vigilant toward a system’s learning and action in the world than an emergency button which one might not get to push in time.

Scientific anti-realists who appeal to the pessimistic induction (PI) claim that the theoretical terms of past scientific theories often fail to refer to anything. But on standard views in philosophy of language, such reference failures prima facie lead to certain sentences being neither true nor false. Thus, if these standard views are correct, then the conclusion of the PI should be that significant chunks of current theories are truth-valueless. But that is semantic anti-realism about scientific discourse—a position most philosophers of (...) science, anti-realists included, consider anathema today. Therefore, proponents of the PI confront a dilemma: either accept semantic anti-realism or reject common semantic views. I examine strategies (with particular emphasis on supervaluations) for the PI proponent to either lessen the sting of this argument, or learn to live with it. 1 Introduction2 Designation Failure 2.1 Designation failure leads to truth-valueless sentences2.1.1 Direct reference theory2.1.2 Fregeanism2.1.3 Accounts of reference-fixing: why ‘phlogiston’ fails to designate 2.2 Objection: sentences exhibiting designation failure are false not truth-valueless 2.3 Avoiding truth-valuelessness via controversial semantic positions3 What to do?

The Pessimistic Induction (PI) states: most past scientific theories were radically mistaken; therefore, current theories are probably similarly mistaken. But mistaken in what way? On the usual understanding, such past theories are false. However, on widely held views about reference and presupposition, many theoretical claims of previous scientific theories are neither true nor false. And if substantial portions of past theories are truth-valueless, then the PI leads to semantic antirealism. But most current philosophers of science reject semantic antirealism. So PI (...) proponents face a difficult choice: accept either semantic antirealism or an unorthodox position on reference and presupposition. (shrink)

This article – which includes a complete translation of Mūlamadhyamakakārikā chapter 2 together with Candrakīrti’s commentary thereon – argues that notwithstanding the many different and often arcane interpretations that have been offered of Nāgārjuna’s arguments against motion, there is really just one straightforward kind of argument on offer in this vexed chapter. It is further argued that this basic argument can be understood as a philosophically interesting one if it is kept in mind that the argument essentially has to do (...) with whether a personal level of description will admit of an exhaustively impersonal explanation.

We determine the exact bounds for the length of an arbitrary reduction sequence of a term in the typed λ-calculus with β-, ξ- and η-conversion. There will be two essentially different classifications, one depending on the height and the degree of the term and the other depending on the length and the degree of the term.

First published in 1959, this book is concerned with the methodology of art history, and so with questions about historical thinking; it enquires what scientific history of art can accomplish, what are its mean and limitations? It contains philosophical reflections on history and begins with chapters on the scope and limitations of a sociology of art, and the concept of ideology in the history of art. The chapter on the concept of "art history without names" occupies the central position in (...) the book — thoroughly discussing the basic philosophical outlook for the whole work. There are also further chapters on psychoanalysis, folk art and popular art. The chapter on the role of convention in the history of art points the way for further study. (shrink)

Global climate change is one of the most daunting ethical and political challenges confronting humanity in the twenty-first century. The intergenerational and transnational ethical issues raised by climate change have been the focus of a significant body of scholarship. In this new collection of essays, leading scholars engage and respond to first-generation scholarship and argue for new ways of thinking about our ethical obligations to present and future generations. Topics addressed in these essays include moral accountability for energy consumption and (...) emissions, egalitarian and libertarian perspectives on mitigation, justice in relation to cap and trade schemes, the ethics of adaptation and the ethical dimensions of the impact of climate change on nature.

Alexander Rosenberg recently claimed (1997) that developmental biology is currently being reduced to molecular biology. cite several concrete biological examples that are intended to impugn Rosenberg's claim. I first argue that although Laubichler and Wagner's examples would refute a very strong reductionism, a more moderate reductionism would escape their attacks. Next, taking my cue from the antireductionist's perennial stress on the importance of spatial organization, I describe one form an empirical finding that refutes this moderate reductionism would take. Finally, I (...) point out an actual example, anterior-posterior axis determination in the chick, that challenges the reductionist's belief that all developmental regularities can be explained by molecular biology. In short, I argue that Rosenberg's position can be saved from Laubichler and Wagner's criticisms and putative counter-examples, but it would not survive a different kind of counter-example. (shrink)

Carnap in the 1930s discovered that there were non-normal interpretations of classical logic - ones for which negation and conjunction are not truth-functional so that a statement and its negation could have the same truth value, and a disjunction of two false sentences could be true. Church ar-gued that this did not call for a revision of classical logic. More recent writers seem to disa-gree. We provide a definition of "non-normal interpretation" and argue that Church was right, and in fact, (...) the existence of non-normal interpretations tells us something important about the condi-tions of extensionality of the classical logical operators.

"This innovative volume argues that any particular kind of music can only be understood in terms of the criteria of the group which makes and appreciates that music. This theme is in sharp contrast to established attitudes to music which utilize 'objectively' conceived aesthetic. These attitudes are revealed in the assumptions underlying most musicology and musical aesthetics including, perhaps paradoxically, the work of a number of cultural radicals such as Lukacs and Adorno. On a more practical level, they manifest themselves (...) both in music education policies and in the policies of arts and broadcasting administrators, who have the power to promote some kinds of music above others.

To paraphrase Freud, what do socialists really want? It is undoubtedly difficult to give a complete answer to this question that all socialists would be satisfied with, but there are some common elements that can hardly be denied. First and foremost among these is the elimination of capitalism; the elimination of capitalism would seem to require the elimination of capitalists. Why might that be desirable? Well, many reasons might be offered, but one is suggested by the very nature of capitalism.

Attempts to justify the objectivity and universality of aesthetic judgment have traditionally rested on unsupported assumptions or mere assertion. This paper offers a fresh consideration of the problem of judgments of taste. It suggests that the problem of securing universal agreement is false and therefore insoluble since it imposes an inappropriate logical criterion on the extent of agreement, which is irrevocably empirical. The variability of judgments of taste actually forms a subject ripe for inquiry by sociologists, psychologists, historians and anthropologists, (...) as well as by aestheticians. Scenic beauty provides a vivid test for the variability of these judgments. (shrink)

This paper examines the critique of Voegelin in Kelsens "Secular Religion". While Kelsen sets out with the false premise that secular world view can in principle have no religious character, his critique of Voegelin remains largely unimpaired by this mistake. With convincing arguments Kelsen criticises (1) Voegelins interpretation of modernity as an age of gnosticism, (2) Voegelins reinterpretation of enlightened and secular philosopher as gnostics in disguise and (3) Voegelins rejection of modern politics and, to a lesser degree, modern science. (...) I have also uploaded the critical margin notes that some person (unfortunately I do not know any more who) had been so friendly to sent me. The paper was originally written in German, but an English translation is available as well. (shrink)

The question of the nature of our knowledge of society has recently been raised in an interesting form by Peter Winch in his monograph, The Idea of a Social Science, and debated in recent issues of Inquiry by A. R. Louch and Winch himself. In this paper I attempt to contribute to this discussion by attacking the problem of the nature of the empirical bases of social scientific knowledge, the main point in dispute between Winch and Louch. I try to (...) construct an argument to show that in specifying the 'data' of social science, we have to introduce an element of 'interpretive understanding' which radically alters the meaning of the term 'empirical base' in social scientific contexts, thus supplementing Winch's argument in his reply to Louch. At the same time, my argument shows, I believe, that this view of the nature of social science does not lead to any arbitrary restrictions on the methods of research pursued by social scientists, as is sometimes imagined. What the argument leads to is the conclusion that our knowledge of society involves distinctive epistemological features that differentiate this kind of knowledge from the kind of knowledge we have in the natural sciences.

This challenging paper presents an ingenious argument for a functionalist theory of mind. Part of the argument: My visual cortex at the back of my brain processes the stimulation to my eyes and then causes other parts of the brain - like the speech centre and the areas involved in thought and movement - to be properly responsive to vision. According to functionalism the whole mental character of vision - the whole of how things look - is fixed purely in (...) the pattern of responses to vision and not in any of the initial processing of vision in the visual cortex. That this functionalist theory of vision is true can be proved with alarming ease. Imagine that just the left side of my visual cortex is replaced by a gadget that has precisely the same input/output relationship to the rest of the brain as the left visual cortex had. According to any view but functionalism, the character of my vision on the right side of my visual field (normally processed by the left visual cortex) would change radically with this change in all the intrinsic properties involved in the visual cortex, with this preservation of nothing but its functional role in bringing about my responses to vision. But, say I, we have enough here to be sure that in such a case there could be no change in the character of my vision. For we know by the stipulation of sameness of output that my responses in speech, thought and movement to the right side of my visual field will be precisely the same as they would have been with the natural left visual cortex and will harmonise just as they would have done with my responses to the other side of my vision. But if half my vision had disappeared or changed I’d be speaking, thinking and acting like someone with problems on the right side of his vision. It is impossible to separate my responses to vision from the character of my vision. The character of my vision is logically determined by the pattern of responses - by nothing but the functional role of my vision. (shrink)

For a while in this article it seems impossible to articulate a compelling reason for refraining from killing an innocent stranger with the press of a button when this would earn one a small prize and would be done with absolutely guaranteed immunity from any punishment or other harm (including even an instantaneous elimination of any chance of a guilty memory, achieved through hypnosis, and an ironclad commitment from God not to condemn the killing). After many failed attempts, a compelling (...) reason for not pushing the button is finally articulated. A distinction is demonstrated between merely apparent, mistaken desires and real desires. One might, for example, have merely an apparent, mistaken desire to be drinking the stuff in a mug of hot mud if one mistakenly believed that the stuff was hot chocolate. One would not really desire to be drinking that stuff. A desire, which must always be based on some belief about what its object is like, would always be open to correction along with the belief on which it depended. This realisation leads to the sweeping principle that one can only really desire what one would be desiring with a hypothetical perfect grasp of all that is involved. If one desires something only because of not fully grasping what that thing is, then one does not really desire it. What one really desires, then, regarding this stranger and pushing the button has to be what one would desire if fully experiencing, among other things, the entire value of the stranger's life from his own as well as every other angle along with the small value for oneself of the prize received on killing him. This equal concern for all is morality, and what is compelling in morality is that what it commands is what everyone really desires. (shrink)

What I should like to explore here is the experience of landscape both through the arts and as an art, an art of environmental appreciation. A clearer understanding of landscape, environment, and art, as well as what it is to "know" in the context of environmental experience, suggests how the arts can contribute to an intimate, engaged experience of landscape, and how this process itself can be construed as an art in which the perceiver is a quasi-artist. I should like (...) to do this through a re-weaving of words and ideas to propose a new fabric for understanding the relation of art, landscape, and perceiver. The threads I want to combine are four: art, environment, landscape, and knowing in the sense of appreciation. I hope to show how the loose-knit texture they form can be spread over a particular landscape in such a way that the landscape will fill the fabric and the fabric integrate the landscape. I realize that I may have over-worked my metaphor, so I shall leave it now, but I hope that it can serve as a guiding image for the relation and application of the ideas I shall be working with.

This is an essay on the tasks and capacities of aesthetic theory and the pitfalls that beset it. I want to show that aesthetics can be enlightening by revealing and studying the facets and dimensions of experiences we call aesthetic, experience that is expansive and revelatory. This kind of experience can also clarify the relation of aesthetics to other areas of knowledge, such as cultural studies, and conversely, the bearing of other disciplines on our aesthetic understanding. Aesthetic theory, however, is (...) easily caught up in secondary, unproductive, and false issues, and these are what gives this essay its title. What is important, I want to argue, is not what we label beautiful or call art but where we find the kind of value experiences traditionally associated with appreciating beauty, natural and artistic, and how we can enhance and develop such experiences. However, this also requires recognizing the converse of such values in the loss, the negation, the desecration of this mode of experience. I conclude by proposing a larger philosophical role for aesthetics. (shrink)

Experience with electronic communication in ethics committees at two hospitals is reviewed and discussed. A listserver of ethics committee members transmitted a synopsis of the ethics consultation shortly after the consultation was initiated. Committee comments were sometimes incorporated into the recommendations. This input proved to be most useful in unusual cases where additional, diverse inputs were informative. Efforts to ensure confidentiality are vital to this approach. They include not naming the patient in the e-mail, requiring a password for access to (...) the listserver, and possibly encryption. How this electronic communication process alters group interactions in ethics committees is a fruitful area for future investigation. (shrink)
