Theories of economic justice are characteristically based on abstract ethical concerns often unrelated to practical distributive results. Two decades ago, Rawls's theory of justice began as a reaction against the alleged ‘sacrifices’ condoned by utilitarian theory. One variant of this objection is that utilitarianism permits gross inequalities, severe deprivations of individual liberty, or even the enslavement of society's least well-off individuals. There are, however, more subtle forms of the objection. In Rawls, it is often waged without any claim that utilitarianism (...) does in fact imply such gross deprivations in actual realworld circumstances. A second variant hinges, rather, on the milder claim that utilitarianism could condone such deprivations or sacrifices in some possible world—the objection being that utilitarianism improperly makes justice contingent, or uncertain, in this way. A third, still more abstract, variant would be that utilitarianism is flawed—not because of any practical distributive result, actual or hypothetical, but in theory —due to the way it treats individuals' interests, or the ‘concept of persons’ it presupposes.

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

In this thesis, Semantics, Meta-Semantics, and Ontology, I provide a critique of the method of truth in metaphysics. Davidson has suggested that we can determine the metaphysical nature and structure of reality through semantic investigations. By contrast, I argue that it is not semantics, but meta-semantics, which reveals the metaphysically necessary and sufficient truth conditions of our claims. As a consequence I reject the Quinean criterion of ontological commitment. In Part I, chapter 1, I argue that the metaphysically primary truth (...) bearers are not propositions, but rather concrete representations, either beliefs or sentences. I show, in chapter 2, that we can give sense to a truth predicate applying to sentences, given a truth operator and quantification into sentence position. I argue that this strategy does not commit us to the existence of propositions serving as truth bearers. In Part II I argue that although we must assign semantic values to sentences and/or predicates, the meaningfulness of these expressions is not thereby explained. In chapter 3 I articulate Davidson’s problem of predication and his solution, but argue that he was wrong to attribute this solution to Tarski. In chapter 4 I examine the semantics of modal languages; I conclude that although they require semantic values for predicates and/or sentences we should be instrumentalists about these theories. In Part III I consider the relationship between truth and existence. In chapter 5, I defend Pluralism about truth: in some domains of discourse, I claim, semantic reference plays a merely instrumental role in explaining truth. In chapter 6, I show that Hume’s Principle, which is committed by the Quinean criterion to the existence of numbers, can be true even though numbers do not exist. In doing so, I appeal to meta-semantic and diachronic considerations. In the conclusion I compare my views on ontology and commitment to Jody Azzouni’s; and in the appendix I suggest how one might pursue diachronic linguistics. (shrink)

Philip Ball explores the science of the shapes we see in nature, revealing how, from the stripes of a zebra to the development of a snowflake or even a human embryo, there is a pattern-forming tendency in the basic processes of nature, and from a few simple themes, and the repetition of simple rules, endless beautiful variations can arise.

We summarize the ethnographic literature illustrating that “abnormal birth” circumstances and “ill omens” operate as cues to terminate parental investment. A review of the medical literature provides evidence to support our assertion that ill omens serve as markers of biological conditions that will threaten the survival of infants. Daly and Wilson (1984) tested the prediction that children of demonstrably poor phenotypic quality will be common victims of infanticide. We take this hypothesis one stage further and argue that some children will (...) be poor vehicles for parental investment yet are not of demonstrably poor quality at birth. We conclude that when people dispose of infants due to “superstitious beliefs” they are pursuing an adaptive strategy in eliminating infants who are poor vehicles for parental investment. (shrink)

An experiment is reported examining dual-process models of belief bias in syllogistic reasoning using a problem complexity manipulation and an inspection-time method to monitor processing latencies for premises and conclusions. Endorsement rates indicated increased belief bias on complex problems, a finding that runs counter to the “belief-first” selective scrutiny model, but which is consistent with other theories, including “reasoning-first” and “parallel-process” models. Inspection-time data revealed a number of effects that, again, arbitrated against the selective scrutiny model. The most striking inspection-time (...) result was an interaction between logic and belief on premise-processing times, whereby belief - logic conflict problems promoted increased latencies relative to non-conflict problems. This finding challenges belief-first and reasoning-first models, but is directly predicted by parallel-process models, which assume that the outputs of simultaneous heuristic and analytic processing streams lead to an awareness of belief - logic conflicts than then require time-consuming resolution.

Perhaps the most salient feature of Rawls's theory of justice which at once attracts supporters and repels critics is its apparent egalitarian conclusion as to how economic goods are to be distributed. Indeed, many of Rawls's sympathizers may find this result intuitively appealing, and regard it as Rawls's enduring contribution to the topic of economic justice, despite technical deficiencies in Rawls's contractarian, decision-theoretic argument for it which occupy the bulk of the critical literature. Rawls himself, having proposed a “coherence” theory (...) of justification in metaethics, must regard the claim that his distributive criterion “is a strongly egalitarian conception” as independently a part of the overarching moral argument. The alleged egalitarian impact of Rawls's theory is crucial again in normative ethics where Rawls is thought to have developed a major counter-theory to utilitarianism, one of the most popular criticisms of which has been its alleged inadequacy in handling questions of distributive justice. Utilitarians can argue, however, as Brandt recently has, that the diminishing marginal utility of money, along with ignorance of income-welfare curves, would require a utility-maximizing distribution to be substantially egalitarian. The challenge is therefore for Rawls to show that his theory yields an ethically preferable degree of equality. (shrink)

Van den Belt recently examined the notion that synthetic biology and the creation of ‘artificial’ organisms are examples of scientists ‘playing God’. Here I respond to some of the issues he raises, including some of his comments on my previous discussions of the value of the term ‘life’ as a scientific concept.

Wason's standard 2-4-6 task requires discovery of a single rule and leads to around 20% solutions, whereas the dual goal (DG) version requires discovery of two rules and elevates solutions to over 60%. We report an experiment that aimed to discriminate between competing accounts of DG facilitation by manipulating the degree of complementarity between the to-be-discovered rules. Results indicated that perfect rule complementarity is not essential for task success, thereby undermining a key tenet of the goal complementarity account of DG (...) facilitation. The triple heterogeneity account received a good degree of support since more varied triple exploration was associated with facilitatory DG conditions, in line with this account's prediction that task success is associated with the creative search of the problem space. The contrast class account (an extension of Oaksford & Chater's, 1994, iterative counterfactual model) was also corroborated in that the generation of descending triples was demonstrated to be the dominant predictor of DG success. We focus our discussion on conceptual ideas relating to the way in which iterative counterfactual testing and contrast class identification may work together to provide a powerful basis for effective hypothesis testing.

Contemporary bioethical theory relies upon the concept of informed consent to protect against abuses of patient autonomy. Due to the complexity of the informed consent process, however, many patients rely more on their trust in their health care providers than they do upon their own ability to decide whether or not to give informed consent. Reformation theologian John Calvin placed a strong emphasis on the decision-maker's duty to respect the trust that others repose in the decision-maker. In keeping with Calvin's (...) concept of the duty to honor that trust, bioethics would do well to complement its current emphasis on informed consent with an emphasis on the protection of patient trust.

The notion of the ‘reasonable expectations of the parties’ plays an important justificatory role in contract law, yet the notion has not been subjected to any sustained analysis in the contract law literature. This article examines the various roles that reasonable expectation plays in contract law and explores the different understandings of the notion that are revealed. It identifies three possible bases for reasonable expectations—an institutional basis, an empirical basis and a normative basis—and examines how reasonable expectations arguments in contract (...) reflect each of these differing justificatory bases. This makes appeals to reasonable expectation in contract law problematic since the differently grounded expectations of the contracting parties are usually the precise site of conflict between them. It is therefore doubtful that conflicts between contracting parties can be resolved solely by identifying and protecting their ‘reasonable expectations’. In the conclusion some speculative comments are offered as to why, given its limited explanatory power, the notion has proved attractive in attempts to explain contract law. (shrink)

This paper employs ethnographic research methods to study a Buddhist meditation practice that takes the walking body as its object. The mundane act of walking is transformed into a meditative object for the purpose of refining states of embodied consciousness. This meditation practice offers a glimpse of the relationship of body to mind, a fundamental concern within the philosophy of mind. The analytic focus of this paper is the practical nature of meditation work. Aspects of Buddhist Philosophy are explored and (...) compared to analytic themes within Phenomenology and Ethnomethodology. (shrink)

This paper is based on case-study research in four English secondary schools. It explores the pressure placed on English and mathematics departments because of their results being reported in annual performance tables. It examines how English and maths departments enact policies of achievement, the additional power and extra resources the pressure to achieve brings and the possibility of resistance.
