An experimental survey was undertakento explore the links between thecharacteristics of a moral issue, the degree ofmoral intensity/moral imperative associatedwith the issue (Jones, 1991), and people'sstated willingness to pay (wtp) for policy toaddress the issue. Two farm animal welfareissues were chosen for comparison and thecontingent valuation method was used to elicitpeople's wtp. The findings of the surveysuggest that increases in moral characteristicsdo appear to result in an increase in moralintensity and the degree of moral imperativeassociated with an issue. Moreover, there (...) was apositive link between moral intensity/moralimperative associated with an issue andpeople's stated wtp for policy to address theissue. The paper discusses the relevance of thefindings of the survey in the context of thedebate concerning the relationship betweenmoral and economic values and the use of thecontingent valuation method to estimatepeople's wtp of policy options with moraldimensions.

It is predicted that the rapid acquisition of new genetic knowledge and related applications during the next decade will have significant implications for virtually all members of society. Currently, most people get exposed to information about genes and genetics only through stories publicized in the media. We sought to understand how individuals in the general population used and understood the concepts of “genetics” and “genes.” During in-depth one-on-one telephone interviews with adults in the United States, we asked questions exploring their (...) basic understanding of these terms, as well as their belief as to the location of genes in the human body. A wide range of responses was received. Despite conversational familiarity with genetic terminology, many noted frustration or were hesitant when trying to answer these questions. In addition, some responses reflected a lack of understanding about basic genetic science that may have significant implications for broader public education measures in genetic literacy, genetic counseling, public health practices, and even routine health care.

In ‘The Presuppositions of Religious Pluralism and the Need for Natural Theology’ I argue that there are four important presuppositions behind John Hick’s form of religious pluralism that successfully support it against what I call fideistic exclusivism. These are i) the ought/can principle, ii) the universality of religious experience, iii) the universality of redemptive change, and iv) a view of how God (the Eternal) would do things. I then argue that if these are more fully developed they support a different (...) kind of exclusivism, what I call rational exclusivism, and become defeaters for pluralism. In order to explain rational exclusivism and its dependence on these presuppositions I consider philosophers J.P. Moreland, William Lane Craig, and Alvin Plantinga, who offer arguments for their forms of exclusivism but I maintain that they continue to rely on fideism at important points. I then give an example of how knowledge of the Eternal can be achieved. (shrink)

The current paper details a restricted semantics for active logic, a time-sensitive, contradictiontolerant logical reasoning formalism. Central to active logic are special rules controlling the inheritance of beliefs in general, and beliefs about the current time in particular, very tight controls on what can be derived from direct contradictions (P &¬P ), and mechanisms allowing an agent to represent and reason about its own beliefs and past reasoning. Using these ideas, we introduce a new definition of model and of logical (...) consequence, as well as a new definition of soundness such that, when reasoning with consistent premises, all classically sound rules are sound for active logic. However, not everything that is classically sound remains sound in our sense, for by classical definitions, all rules with contradictory premises are vacuously sound, whereas in active logic not everything follows from a contradiction.

Artificial Intelligence, in press. Abstract: For some time we have been developing, and have had significant practical success with, a time-sensitive, contradiction-tolerant logical reasoning engine called the active logic machine (ALMA). The current paper details a semantics for a general version of the underlying logical formalism, active logic. Central to active logic are special rules controlling the inheritance of beliefs in general (and of beliefs about the current time in particular), very tight controls on what can be derived from direct (...) contradictions (P &￢P), and mechanisms allowing an agent to represent and reason about its own beliefs and past reasoning. Furthermore, inspired by the notion that until an agent notices that a set of beliefs is contradictory, that set seems consistent (and the agent therefore reasons with it as if it were consistent), we introduce an “apperception function” that represents an agent’s limited awareness of its own beliefs, and serves to modify inconsistent belief sets so as to yield consistent sets. Using these ideas, we introduce a new definition of logical consequence in the context of active logic, as well as a new definition of soundness such that, when reasoning with consistent premises, all classically sound rules remain sound in our new sense. However, not everything that is classically sound remains sound in our sense, for by classical definitions, all rules with contradictory premises are vacuously sound, whereas in active logic not everything follows from a contradiction.

We discuss why, contrary to claims recently made by P.W. Anderson, decoherence has not solved the quantum measurement problem.

James A. Anderson and Charles Weijer take the wage payment model proposed by Neil Dickert and Christine Grady and extend the analogy of research participation to unskilled wage labor to include just working conditions. Although noble in its intentions, this moral extension generates unsavory outcomes. Most notably, Anderson and Weijer distinguish between two types of research subjects: occasional and professional. The latter, in this case, receives benefits beyond the moral minima in the form of “the right to meaningful (...) work.” The problem is that meaningful work can itself be a form of inducement, and consequently, may in fact increase the incidence of inducement contrary to the intentions of the wage payment model.

Analysis of Emmy Noether’s 1918 theorems provides an illuminating method for testing the consequences of “coordinate generality”, and for exploring what else must be added to this requirement in order to give general covariance its far-reaching physical significance. The discussion takes us through Noether’s first and second theorems, and then a third related theorem due originally to F. Klein. Contact will also be made with the contributions of, principally, J.L. Anderson, A. Trautman, P.A.M. Dirac, R. Torretti and the father (...) of the whole business, A. Einstein (an apparent shift in Einstein’s thinking on the significance of general covariance between 1916 and 1918 is highlighted). (shrink)

The Routley-Meyer relational semantics for relevant logics is extended to give a sound and complete model theory for many propositionally quantified relevant logics (and some non-relevant ones). This involves a restriction on which sets of worlds are admissible as propositions, and an interpretation of propositional quantification that makes ∀ pA true when there is some true admissible proposition that entails all p -instantiations of A . It is also shown that without the admissibility qualification many of the systems considered are (...) semantically incomplete, including all those that are sub-logics of the quantified version of Anderson and Belnap’s system E of entailment, extended by the mingle axiom and the Ackermann constant t . The incompleteness proof involves an algebraic semantics based on atomless complete Boolean algebras. (shrink)

In their book Entailment, Anderson and Belnap investigate the consequences of defining Lp (it is necessary that p) in system E as (pp)p. Since not all theorems are equivalent in E, this raises the question of whether there are reasonable alternative definitions of necessity in E. In this paper, it is shown that a definition of necessity in E satisfies the conditions { E Lpp, EL(pq)(LpLq), E pLp} if and only if its has the form C 1.C2 .... Cnp, (...) where each C iis equivalent in E to either pp or ((pp)p)p. (shrink)

Dienes & Perner (D&P) argue that nondeclarative knowledge can take multiple forms. We provide empirical support for this from two related lines of research about the development of mathematical reasoning. We then describe how different forms of procedural and declarative knowledge can be effectively modeled in Anderson's ACT-R theory, contrasting this computational approach with D&P's logical approach. The computational approach suggests that the commonly observed developmental progression from more implicit to more explicit knowledge can be viewed as a consequence (...) of accumulating and strengthening mental representations.

Abstract Medical futility is commonly understood as treatment that would not provide for any meaningful benefit for the patient. While the medical facts will help to determine what is medically appropriate, it is often difficult for patients, families, surrogate decision-makers and healthcare providers to navigate these difficult situations. Often communication breaks down between those involved or reaches an impasse. This paper presents a set of practical strategies for dealing with cases of perceived medical futility at a major cancer center. Content (...)

The validity of an entailment has nothing to do with whether or not the components are true, false, necessary, or impossible; it has to do solely with whether or not there is a necessary connection between antecedent and consequent. Hence it is a mistake (we feel) to try to build a sieve which will strain out entailments from the set of material or strict implications present in some system of truth-functions, or of truth-functions with modality.

This paper shows that the Dawson technique of modelling deontic logics into alethic modal logics to gain insight into deontic formulas is not available for modelling a normal (in the spirit of Anderson) relevance deontic modal logic into either of the normal relevance alethic modal logics R S4or R M. The technique is to construct an extension of the well known entailment matrix set M 0and show that the model of the deontic formula P (A v B). PA v (...) PB is excluded. (shrink)

We have been witnessing more than two hundred years of successful formation and spread of the nation-state. As a historical reminder, let me quote great French historian of the nineteenth century, Jules Michelet; in spite of its somewhat sentimental tone, his view on the unification of France is typical of what any nationalist would like to say about the successful creation of an ethno-national state: "This unification of France, this destruction of parochial spirit is often considered as the simple result (...) of the conquest of provinces. But a conquest can glue together, chain together the hostile parts, never unite them: the conquest and the war have only opened provinces to each other, and has given to isolated populations an opportunity to meet each other; the quick and lively sympathy of Gallic genius, its social instinct, has done the rest of the work. What a strange event! These provinces, of differing climate, customs and language have understood each other, fallen in love with each other, felt solidarity towards each other….”(Michelet, Histoire de la france, t. III; 1844, Histoire de la France, Anthologized in Saly et. al.1996, p. 115) Saly, P., Gerard, A., Gervais, C. and Rey, M.P., “Nations et nationalismes en Europe 1848-1914., my translation)" Contemporary sociologists express similar thoughts in a different rhetorical garb. They stress the advantages of nation-forming along ethnonational lines. By offering to people a culture in languag(es) they actually spoke, by encouragement of the formation of more local elites, directly in contact with their electorate, and by promoting capitalist mode of production it has enabled the massive democratization. As many sociologists , prominently Anderson and Gellner, have pointed out, democracy and nationalism go together.. (shrink)

A system S has the “converse Ackermann property” (C.A.P.) if (A -> B) -> C is unprovable in S whenever C is a propositional variable. In this paper we define the fragments with the C.A.P. of some well-know propositional systems in the spectrum between the minimal and classical logic. In the first part we succesively study the implicative and positive fragments and the full calculi. In the second, we prove by a matrix method that each one of the systems has (...) the C.A.P. Thus, we think the problem proposed in Anderson & Belnap (1975) § 8.12 has been solved. (shrink)

Philosophers on Education provides the most comprehensive history of philosphers' views and impacts on the direction of education, from Plato to Dewey. As Amelie Oksenberg Rorty explains in describing a history of education, we are essentially describing and gaining the clearest understanding of the issues that presently concern and divide us. Philosophical reflection on education has usually been directed to the education of rulers, to those who are presumed to preserve and transmit--or to redirect and transform--the culture of sociey, its (...) knowledge and values. Every historical era is marked by a struggle among claimants to that power. It is only late in the history of liberal democracies that educational policy was formulated for and directed toward autonomous individuals who structure their own lives. The contributors to this collection recognize that history remains actively embedded and expressed in society's beliefs and practices, and that the study of the history of philosophy mandates reflection on its implications for education. The all new essays are written by some of the finest contemporary philosophers: Elizabeth Anderson, Annette C. Baier, Frederick B. Beiser, Eva T. H. Brann, M.F. Burnyeat, William Galston, Daniel Garber, Peter Gay, Alvin I. Goldman, Moshe Halbertal, Tova Hartman Halbertal, Simon Harrison, Barbara Herman, Genevieve Lloyd, Alasdair MacIntyre, Richard W.

The Knower Paradox is an element of the class of paradoxes of self-reference. It demonstrates that any theory Ó which (1) extends Robinson arithmetic Q, (2) includes a unary knowledge predicate K, and (3) contains certain elementary epistemic principles involving K is inconsistent. In this paper I present different versions of the Knower Paradox (both in the framework of the first-order arithmetic and in the modal logic). There are several solutions of the paradox. Some of them I discuss in detail, (...) namely solution developed within modal logic, solution proposed by C. A. Anderson and solution proposed by P. Égré. The common defect of these proposals is that they developed a connection between the concepts of knowledge and provability. Finally, I suggest a solution using the basic ideas of the revision theory of definitions. (shrink)

The question of paradox in Christian theology continues to attract attention in contemporary philosophical theology. Much of this attention understandably centers on the epistemological problems paradoxical claims pose for Christian faith. But even among those who conclude that certain points of Christian theology are paradoxical and that belief in paradoxical points of doctrine is epistemically supportable, concepts of the nature and function of paradox in Christian theology differ significantly. In this essay, after briefly noting the diversity of phenomena that count (...) as paradoxes in contemporary discourse, I critique two of the most helpful accounts of paradox in Christian theology available – James Anderson's and C. Stephen Evans's – on the way to proposing an alternative definition. That definition combines the most helpful features of those two accounts while correcting certain weaknesses in each. The result is a definition of paradox as a particular kind of mystery that fits the Reformed strand of Christian theology particularly well and involves a compelling analysis of the spirituality of the phenomenon of paradox in theology.
