I begin by refuting Davidson’s classic account of akrasia, which turns on a purported distinction between judging p and judging p “all things considered.” The upshot of this refutation is that an adequate account of akrasia must turn on a distinction between different ways in which the agent can make judgments about her practical reasons. On the account I propose, an akratic agent makes an existential judgment that there is some decisive practical reason to act in a certain way without (...) also knowing what that reason is. An agent can do what such a reason requires only by deviating from the conditions under which her action would be a response to it. The possibility of akrasia is a consequence of our concern not only to perform actions that match what our reasons require but also to manifest reasons in conduct that they inform. (shrink)

This is a book about the nature of film: about the nature of moving images, about the viewer's relation to film, and about the kinds of narrative that film is capable of presenting. It represents a very decisive break with the semiotic and psychoanalytic theories of film which have dominated discussion. The central thesis is that film is essentially a pictorial medium and that the movement of film images is real rather than illusory. A general theory of pictorial representation is (...) presented, which insists on the realism of pictures and the impossibility of assimilating them to language. It criticizes attempts to explain the psychology of film viewing in terms of the viewer's imaginary occupation of a position within the world of film. On the contrary, film viewing is nearly always impersonal. (shrink)

The doctrine of promissory fraud holds that a contractual promise implicitly represents an intent to perform. A promisor's conditional intent to perform poses a problem for that doctrine. It is clear that some undisclosed conditions on the promisor's intent should result in liability for promissory fraud. Yet no promisor intends to perform come what may, so there is a sense in which all promisors conditionally intend to perform. Building on Michael Bratman's planning theory of intentions, this article provides a theoretical (...) account of the distinction between “foreground” and “background” conditions on intentions in general and then explains why foreground conditions on a promisor's intent to perform are likely to result in material promissory misrepresentation, while background conditions are not. The difference between foreground and background conditions lies in whether the agent accepts the satisfaction of the condition for the purposes of her practical reasoning. A promisor's nonacceptance of a condition on her intent to perform is material because it is likely to affect her preperformance deliberations and investment in the transaction, as well as her willingness to seek agreement with the promisee on how to fill contractual gaps.

During the inter war period, European Catholic authors exhibited two different approaches to the question of just war. One approach was articulated at the “Fribourg Conventus,” a 1931 meeting of French, Swiss, and German theologians, whose subsequent declaration (Conventus de bello, published in 1932) called for a reformulation of Catholic teaching based on the premise that the traditional just‐war doctrine had been superseded by developments in international law. A competing approach was articulated by the Dutch Jesuit Robert Regout, who maintained (...) that the just‐war doctrine could contribute to the formation of international law by providing a much‐needed normative foundation for the use of armed force by individual states in redress of their violated rights. After presenting these two approaches and explaining how they differ, this essay shows how the outlook of the Conventus de bello is reflected in subsequent papal statements on armed force—to the detriment of the traditional terminology of just war.

Richness theory offers an alternative to the paradigms that have dominated the short history of environmental ethics as a self-conscious field. This alternative theoretical paradigm defines intrinsic value as “richness”—a synonym for “organic unity” or “unity in diversity.” Richness theory can handily reconcile two kinds of ideas that seem to be in tension with each other:that (1) an individual human being has a greater worth than an individual organism of just about any other species; and (2) yet the world would (...) be a better place with substantially fewer humans and/or less consumption per capita, thus leaving more resources for other species.The mutual compatibility of such ideas within the framework of richness theory can be demonstrated both verbally and through a simplified mathematical model.

Yet, in broader terms, formal epistemology is not merely a methodological tool for epistemologists, but a discipline in its own right. On this programmatic view, formal epistemology is an interdisciplinary research program that covers work by philosophers, mathematicians, computer scientists, statisticians, psychologists, operations researchers, and economists who aim to give mathematical and sometimes computational representations of, along with sound strategies for reasoning about, knowledge, belief, judgment and decision making.

The doctrine of double effect (DDE) can have two different functions, permissive and restrictive. According to the first function, agents are exculpated from the negative consequences of their actions, consequences that would be deemed illicit were they intentionally chosen. According to the second, agents are reminded that they are responsible, albeit in a distinctive manner, for the foreseeable damages that flow from their chosen actions. Aquinas has standardly been credited with a permissive version of DDE. I argue by contrast (drawing (...) on the treatment of this issue in my Thomas Aquinas on War and Peace, Cambridge University Press, 2017) that the permissive version results from a misreading of Sum. theol. II-II, q. 64, a. 7. Other texts in the same work indicate that he embraced a restrictive version of DDE. (shrink)

[opening paragraph]: The authors are to be congratulated for this daring and imaginative attempt to discuss art and aesthetic experience in neurological terms. The core of the argument is the relevance of the peak shift effect to our understanding of aesthetics. The application of this well-known principle of animal discrimination learning certainly does seem plausible and appropriate in the context.

What is the role (or roles) of mathematical theory in ecology and evolutionary biology? How does the construction of such theory advance our understanding? The lack of clear answers to this pair of questions has been a source of controversy both within the sciences themselves, and in the philosophical discussions of these sciences as well. In an attempt to shed some light on these issues, I look at what some biologists have had to say on the matter and at some (...) particular examples. I then draw some morals about the constraints on a successful philosophical treatment of the problem and on the limitations of current philosophical approaches to this type of theoretical explanation.

The charges of fideism and relativism have long been leveled against Wittgensteinian philosophy of religion. However, the philosopher most influenced by Wittgenstein's understanding of religion, D. Z. Phillips, is guilty of neither fideism nor conceptual scheming. The contribution of Wittgenstein to an understanding of religious belief is much more nuanced than critics generally appreciate. Likewise, the relationship of Wittgenstein's philosophy to that of Davidson and to pragmatism, especially in its Rortyan manifestations, is shown to be friendlier than is often recognized.

Argues for an approach to the interpretation of text‐based works within which the idea of a communicative intention is central. The communicative approach, apart from providing detailed, illuminating, and testable theories, transposes very well from conversational exchange to the interpretation of text‐based works, and promises to illuminate aesthetic aspects of our engagement with works. Examines the consequences of this approach for the issue of pluralism about interpretation.

This paper explores how the Generalized Continuum Hypothesis (GCH) arose from Cantor's Continuum Hypothesis in the work of Peirce, Jourdain, Hausdorff, Tarski, and how GCH was used up to Gödel's relative consistency result.

The recent conception of biodiversity proposed by James Maclaurin and Sterelny was developed mostly with macrobiological life in mind. They suggest that we measure biodiversity by dividing life into natural units (typically species) and quantifying the differences among units using phenetic rather than phylogenetic measures of distance. They identify problems in implementing quantitative phylogenetic notions of difference for non-prokaryotic species. I suggest that if we focus on microbiological life forms that engage in frequent, promiscuous lateral gene transfer (LGT), and their (...) associated reticulated phylogenies, we need to rethink the notion of species as the natural unit, and we discover additional problems with phylogenetic notions of distance. These problems suggest that a phenetic approach based on morphospaces has just as much appeal, if not more, for microbes as they do for multi-cellular life. Facts about LGT, however, offer no new insight into the additional challenge of reconciling units and differences into a single measure of biodiversity. (shrink)

In this paper, I provide an account of what is frequently called Socrates’s “method,” and, more specifically, of what one is being asked by Socrates when he asks “what is x?” I argue that one is being asked to change one’s life, and to orient one’s life around the pursuit of wisdom. To answer Socrates’s question is to subject oneself to a process of extracting from oneself one’s accumulated prejudices; doing so requires one to abandon, not just ideas that have (...) been demonstrated to be false, but the aspects of one’s life that have been built around those previous un-reflected upon ideas. This means that the cumulative commitments of adulthood—predicated as many of them often are on un-reflected-upon presumptions—prevent initiation into philosophical life. The call to do philosophy is, for Socrates, the call to subject oneself to perpetual transformation, limiting who is capable of its pursuit. (shrink)

Exploring Aristotle's concept of logos, this volume advances our understanding of it as a singular feature of human nature by arguing that it is the organizing principle of human life itself. Tracing its multiple meanings in different contexts, including reason, logic, speech, ratio, account, and form, contributors highlight the ways in which we can see logos in human thinking, in the organizing principles of our bodies, in our perception of the world, in our social and political life, and through our (...) productive and fine arts. Through this focus, logos reveals itself not as one feature amongst others, but instead as the feature that organizes all others, from the most "animal" to the most "spiritual." By presenting logos in this way, readers gain a complex account of the philosophy of human nature. (shrink)

The concept of population is central to ecology, yet it has received little attention from philosophers of ecology. Furthermore, the work that has been done often recycles ideas that have been developed for evolutionary biology. We argue that ecological populations and evolutionary populations, though intimately related, are distinct, and that the distinction matters to practicing ecologists. We offer a definition of ecological population in terms of demographic independence, where changes in abundance are a function of birth and death processes alone. (...) However, demographic independence is insufficient on its own so we supplement it with the idea of shared habitat. An ecological population is a group of organisms of the same species in a habitat that manifests DI. Given the importance of metapopulation dynamics to modern ecology, an account of ecological population must apply to this domain as well. Thus, we extend our definition of ecological population to the metapopulation. To facilitate the extension, we introduce the metahabitat—a collection of spatially segregated habitat patches shared by a single DI population. This enables us to diagnose some unhelpful trends in the metapopulation literature and emphasize the importance of habitat dynamics in pursuit of the goals of theoretical ecology and conservation biology.

This paper describes the application of eight statistical and machine-learning methods to derive computer models for predicting mortality of hospital patients with pneumonia from their findings at initial presentation. The eight models were each constructed based on 9847 patient cases and they were each evaluated on 4352 additional cases. The primary evaluation metric was the error in predicted survival as a function of the fraction of patients predicted to survive. This metric is useful in assessing a model’s potential to assist (...) a clinician in deciding whether to treat a given patient in the hospital or at home. We examined the error rates of the models when predicting that a given fraction of patients will survive. We examined survival fractions between 0.1 and 0.6. Over this range, each model’s predictive error rate was within 1% of the error rate of every other model. When predicting that approximately 30°K of the patients will survive, all the models have an error rate of less than 1.5%. The models are distinguished more by the number of variables and parameters that they contain than by their error rates; these differences suggest which models may be the most amenable to future implementation as paper-based guidelines.
