David Lewis is widely credited with the first formulation of common knowledge and the first rigorous analysis of convention. However, common knowledge and convention entered mainstream game theory only when they were formulated, later and independently, by other theorists. As a result, some of the most distinctive and valuable features of Lewis' game theory have been overlooked. We re-examine this theory by reconstructing key parts in a more formal way, extending it, and showing how it differs from more (...) recent game theory. In contrast to current theories of common knowledge, Lewis' theory is based on an explicit analysis of the modes of reasoning that are accessible to rational individuals and so can be used to analyse the genesis of common knowledge. Lewis' analysis of convention emphasises the role of inductive reasoning and of salience in the maintenance of conventions over time.

Moral philosophers typically have confronted two distinct kinds of problems. First, they have attempted to discover the supreme principle of morality and show how it should influence our conduct by indicating what specific virtues, obligations, laws, and way of life it would require. Second, they have tried to demonstrate that we ought to live according to its demands and do what is morally right even when our immediate desires pull us in the opposite direction.

A relative value of life dependent on age has been produced from a survey of 721 randomly selected individuals together with other observations of professional practice. The results are presented in diagrammatic form. If two identical people, except for age, present for medical treatment for a life-threatening condition and only one can be treated then the diagram indicates what the choice should be.

Romanticism is recognized as a wellspring of modern-day environmental thought and enthusiasm for nature-preservation, but the character of the affinities between the two is less well understood. Essentially, the Romantics realised that nature only becomes a matter for ethical concern, inspiration and love when the mind and sensibility of the human observer/agent are properly attuned and receptive to its meaning. That attunement involves several factors: a more appropriate scientific paradigm, a subtler appreciation of the impact that the setting of human (...) dwelling, especially landscape, may have on character; the discovery of 'life' and spontaneity as a motif in science and art; a deeper and more complex sense of time; and a feel for place drawn from the life-world rather than physics or economics. Romanticism invented a new language and set of descriptions to illuminate all of these things, one we neglect or forget at our peril. (shrink)

This multidisciplinary volume documents the resurrection of the importance of narrative to the study of individuals and groups and argues that narrative may become a lingua franca of future debates in the human sciences.

Environmental theorists, seeking the origin of Western exploitative attitudes toward nature, have directed their attacks against 'humanism'. This essay argues that such criticisms are misplaced. Humanism has much closer affinities to environmentalism than the latter' s advocates believe. As early as the Renaissance, and certainly by the late eighteenth century, humanists were developing historically-conscious, hermeneutically-grounded modes of understanding, rather than the abstract, mathematical models of nature often associated with them. In its twentieth-century versions humanism also shares much of the mistrust (...) of consumerism, instrumental reason, and 'worldlessness' that marks environmentalist literature. Nevertheless, humanism is indeed committed to the principle that human beings are and ought to be free, and opposes theoretical approaches that suppress freedom. Reconciling humanism and environmentalism thus involves two steps: resisting the former's tendency to treat nature and freedom as metaphysical polarities, and drawing environmental theory away from flirtation with deterministic, biologistic worldviews. The essay concludes by suggesting Aldo Leopold's A Sand County Almanac as the paradigm case of environmental thought with roots in humanist approaches. (shrink)

In those twenty or so pages of section xi of Part Two of the Philosophical Investigations in which Wittgenstein discusses the concept of noticing an aspect and its place among the concepts of experience, there are three passages which are explicitly concerned with the relations between seeing and interpreting in the experience of noticing an aspect.

Recent developments in themethodology of economics have drawn uponpragmatist and realist philosophies of socialscience. These recent developments areoutlined. It is argued that a specific variantof realist philosophy known as critical realismcan provide the basis for a prescriptiveeconomic methodology that is not susceptible topragmatist criticisms.

Although death by neurologic criteria is legally recognized throughout the United States, state laws and clinical practice vary concerning three key issues: the medical standards used to determine death by neurologic criteria, management of family objections before determination of death by neurologic criteria, and management of religious objections to declaration of death by neurologic criteria. The American Academy of Neurology and other medical stakeholder organizations involved in the determination of death by neurologic criteria have undertaken concerted action to address variation (...) in clinical practice in order to ensure the integrity of brain death determination. To complement this effort, state policymakers must revise legislation on the use of neurologic criteria to declare death. We review the legal history and current laws regarding neurologic criteria to declare death and offer proposed revisions to the Uniform Determination of Death Act and the rationale for these recommendations.

At the heart of Levinas’s work is the apparently simple idea that through the encounter with another person, we are forced to give up our self-concern and take heed of the ethical relation between us. But, while simple on the surface, when one tries to characterize it in more detail, it can be hard to fit together the various ways in which Levinas talks about this relation and to identify precisely what he took its normative structure to be, as this (...) is described in a number of apparently different ways, that are not obviously compatible or equivalent, such as “command,” “call,” “summons,” “demand,” and so on. In this chapter, we intend to focus on these different characterizations and show what makes them different while also endeavoring to find a way in which Levinas’s conception may nonetheless be fitted together into a coherent account of the face-to-face encounter that is at the heart of his ethics. We will begin by considering the different normative terms used to characterize the encounter in that text and show how they are conceptually distinct from one another; we will then offer a way to read Levinas’s position to nonetheless show how these different normative relations can be fitted together into a stable position.

Being able to ask others to do things, and thereby giving them reasons to do those things, is a prominent feature of our interpersonal lives. In this paper, I discuss the distinctive normative status of requests – what makes them different from commands and demands. I argue for a theory of this normative phenomenon which explains the sense in which the reasons presented in requests are a matter of discretion. This discretionary quality, I argue, is something that other theories cannot (...) accommodate, though it is a significant aspect of the relations that people stand in to one another, and the kinds of practical reasons that flow from those relations.

Some reasons are thought to depend on relations between people, such as that of a promiser to a promisee. It has sometimes been assumed that all reasons that are relational in this way are moral obligations. I argue, via a counter example, that there are non-obligatory relational reasons. If true, this has ramifications for relational theories of morality.

This paper is about the similarity between the appreciation of a piece of art, such as a cherished music album, and the loving appreciation of a person whom one knows well. In philosophical discussion about the rationality of love, the Qualities View (QV) says that love can be justified by reference to the qualities of the beloved. I argue that the oft-rehearsed trading-up objection fails to undermine the QV. The problems typically identified by the objection arise from the idea that (...) love-worthy qualities could be coarse-grained, when in fact they must be fine-grained. The analogy with appreciation of aesthetic qualities helps to draw out this point. Once the fine-grained nature of love-worthy qualities is properly understood, it is clear that critics of the QV cannot rely on the trading-up objection to motivate its rejection. Moreover, the paper’s core argument helps to illuminate the persistently aesthetic nature of interpersonal affections. (shrink)

It is common for people to be sensitive to aesthetic qualities in one another’s speech. We allow the loveliness or unloveliness of a person’s voice to make impressions on us. What is more, it is also common to allow those aesthetic impressions to affect how we are inclined to feel about the speaker. We form attitudes of liking, trusting, disliking or distrusting partly in virtue of the aesthetic qualities of a person’s speech. In this paper I ask whether such attitudes (...) could ever be legitimate. This is a microcosm of the broader issue of whether people’s aesthetic qualities in general can justify the interpersonal valuing-attitudes that they so often cause. I draw from recent discussions of body aesthetics to articulate a pair of challenges. One challenge says that aesthetic judgements of speech are reliant on unjustifiable prejudices. The other holds that a person’s aesthetic qualities are irrelevant to whether they should be liked. Against these challenges I argue that some speech can bear aesthetic qualities which are not reliant on prejudice and which are relevant to whether the speaker should be liked. I develop this argument through an analysis of the concept of lyricism. (shrink)

Second-person relations are relations between individuals knowingly engaged in interaction with one another. These are the social contexts within which it is appropriate for one to think of and address another as ‘you’. This dissertation explores the practical consequences for agents of relating to others in this fashion. A critical analysis is offered of Stephen Darwall’s theory of moral obligations in terms of demands that can be addressed from the perspective of a second-person. On the basis of the criticisms raised, (...) a broader conception of ‘second-personal reasons’ is advanced according to which there are a variety of species of practical reasons that are essentially grounded in second-person relations between agents, besides moral obligations. A paradigm case of such a species is the reasons that are presented in requests, and one chapter of this work is devoted to explaining this power people often grant to others: to intentionally create new, discretionary reasons for them. Drawing from several historical antecedents – particularly Martin Buber, Simone Weil and Emmanuel Levinas – the analysis of second-personal reasons is extended to include a discussion of the proper object of agapic love, and a discussion of the possible significance that face-to-face encounters may have for moral epistemology.
