Philosophers disagree, with some rare exceptions. One of those exceptions is the broadest-brush account of what language is. Language is a system of signs used for the communication of --well, and here the agreement begins to break down--thoughts, ideas, messages, propositions or propositional contents, intentions, and a host of technical terms offer themselves to chink the cracks. A list of philosophers subscribing would be impossible to complete. Locke, Carnap, Augustine, Hobbes, Fodor, Katz, Chomsky, Derrida, --well, and on and on. Easier (...) would be to list those who dissent. Heraclitus, Wittgenstein, maybe J.L. Austin, Frank Ebersole, and NOT on and on. The first chapter lays out the view that language is a system of signs in sympathetic terms. The second provides a selection of what are usually called “ordinary language” arguments against the view--reminders about how the view requires us to think in terms which are not consistent with how we think about language and signs when we are not doing philosophy. Those arguments have been unpersuasive among philosophers, and Chapter Three begins the work of investigating separate pieces of the view in detail. Chapter Three takes up an argument for the view which is familiar among philosophers, using Jerry Fodor’s formulation: we cannot be thinking in a public, natural language, because animals and preverbal infants think with no such language. I show this argument is not an argument at all but is rather an expression of the view in question. Chapter Four takes up the argument that the relations between particular words and their meanings is arbitrary or conventional rather than natural or necessary, otherwise there would be only one language among mankind. I argue that the alternatives (conventional vs. natural or necessary) are both generated by taking the division between words and their meanings to be the division between signs and signified--in other words, the question is a result of adopting the view of language as signs. Attempts to argue for the legitimacy of the question without taking the view for granted only serve to call it into question more. In Chapter Five I investigate whether we talk in order to communicate something which is otherwise hidden and invisible. We are tempted to think that you and I talk because I cannot read your mind or you mine. Though Wittgenstein has a famous set of comments on the notion of a private language, it remains a strong temptation to think that language gives public form to something (thoughts, ideas, intentions, feelings, content, meaning) which without language would be unknowable to all but the person whose something it is. Examples help point to the incoherence of this view and show that even if it were not incoherent, remedying the invisibility of those internal whatnots would still leave us with a need for language. Chapter Six takes up a hoary question about boundaries of effability--the possibility that there are limits to what can be said which are more restrictive than what can be thought or felt. The account of language as signs provides one easy way to make sense of this idea, but investigation into examples shows the problem is not one that makes sense unless we just grant that account. Chapter Seven investigates how to make sense of the notion that there are things which are in language and other things which are not. I spell out how the view of language as signs gives us a way to think this, and then show how one reaction to finding problems with the notion resonates with Wittgenstein’s early work and with some work of Jacques Derrida, who bite similar bullets and agree that everything is language, that the limits of language are the limits of our world. I then subject that reaction to critical investigation using examples, which reveals their reaction as a rear-guard attempt to save the view of language as signs. Chapter Eight uses examples as guides toward alternative views of language, feeling our way toward what language might be if it is not a system of signs. Finally, the appendix takes up what I take to be the serious arguments against the methods I use in this work, the first two articulated by John Searle (“the assertion fallacy”) and H. P. Grice (“conversational implicature”), and another the generally unspoken belief that philosophical work is like scientific work. (shrink)

This chapter suggests that descriptive epidemiological studies like the Global Burden of Disease Study can usefully be divided into four tasks: describing individuals’ health states over time, assessing their health states under a range of counterfactual scenarios, summarizing the information collected, and then packaging it for presentation. The authors show that each of these tasks raises important and challenging ethical questions. They comment on some of the philosophical issues involved in measuring health states, attributing causes to health outcomes, choosing the (...) counterfactual against which to assess causes, aggregating and summarizing complex information across multiple domains, discounting, age-weighting, handling fetal deaths, measuring health inequalities, representing uncertainty, and assessing personal responsibility for health outcomes.

We propose a new approach for tracing value change. Value change may lead to a mismatch between current value priorities in society and the values for which technologies were designed in the past, such as energy technologies based on fossil fuels, which were developed when sustainability was not considered a very important value. Better anticipating value change is essential to avoid a lack of social acceptance and moral acceptability of technologies. While value change can be studied historically and qualitatively, we (...) propose a more quantitative approach that uses large text corpora. It uses probabilistic topic models, which allow us to trace values that are latent. We demonstrate the approach for five types of value change in technology. Our approach is useful for testing hypotheses about value change, such as verifying whether value change has occurred and identifying patterns of value change. The approach can be used to trace value change for various technologies and text corpora, including scientific articles, newspaper articles, and policy documents. (shrink)

In this paper I explore and defend the idea that those who struggle intellectually in theistic religious practice can be given a good reason to persist in it by treating their continuing practice as a way of paying tribute to people and projects and personal relationships and indeed to the whole moral dimension of human life, expressing how important and profoundly significant these things are to them. This ‘tribute of faith’ is a gesture that one makes with one’s life—a moral (...) gesture. The key thought is that the sayings and other doings of a religious life allow one to treat the world as one in which the things, such as projects and people, that are, for one, most deeply imbued with moral value will achieve fulfilment—a fulfillment that without the truth of religious claims they would often be denied.

The contributions in the first part Re-modelling logic of this volume take account of formal logic in the theory of rational argumentation.

By weakening an inference rule satisfied by logic daC, we define a new paraconsistent logic, which is weaker than logic \ and G′ 3, enjoys properties presented in daC like the substitution theorem, and possesses a strong negation which makes it suitable to express intutionism. Besides, daC ' helps to understand the relationships among other logics, in particular daC, \ and PH1.

A Dirac-like equation for a massive field obeying the classical Proca equations of motion (PMO) is proposed in close analogy with Majorana’s construct for Maxwell electrodynamics. Its underlying algebraic structure is examined and a plausible physical interpretation is discussed. The behavior of the PMO equations in the presence of an external electromagnetic field is also investigated in the low energy limit, via unitary transformations similar to the Foldy-Wouthuysen canonical transformation for a Dirac fermion.

As the most famous woman scientist of the twentieth century, there has been no shortage of books and articles on the life and career of Marie Curie . Her role as a director of a laboratory-based research school in the new scientific field of radioactivity, a field which embraced both chemistry and physics, however, has never been examined. In recent years, there has been a growing interest in the question of research schools, and Morrell, Ravetz, Geison, and Klosterman, amongst others, (...) have written on this subject. Using, in part, the methodology of Morrell, this paper investigates the role of Marie Curie as a school director in the Paris Faculty in the years 1907–14, examining the work and characteristics of her school and assessing her effectiveness as a director.
