Recently, Jonathan Bennett has said some interesting, but mistaken, things about certain themes in Berkeley's philosophy. His comments are interesting because they direct us to a careful scrutiny of Berkeley's arguments and methodology in the often neglected Draft to the Introduction to the Principles, and mistaken because Bennett misinterprets these arguments and methodology. I would like to correct those mistakes because an understanding of Berkeley's Draft is helpful in interpreting the Introduction, which in turn is important for our understanding of (...) not only his philosophical methodology, but also for an adequate interpretation of some of his substantive philosophical claims. I will argue that Bennett misinterprets Berkeley's deleted comments and arguments concerned with two Lockean themes, classification and understanding, as presented in several passages from the Draft which did not appear in the published Introduction to the Principles. In both cases Bennett's confusion is a failure to grasp Berkeley's strategy and target in his attacks upon Locke and the theses he takes Locke to hold. Read in their unedited form the deleted passages not only indicate that Bennett misinterprets them, but they also are suggestive of some interesting philosophical comments on Berkeley's part.

Written in a relaxed, readable style, A Concise Introduction to Pure Mathematics leads students gently but firmly into the world of higher mathematics. It provides beginning undergraduates with a rigourous grounding in the basic tools and techniques of the discipline and prepares them for further more advanced studies in analysis, differential equations, and algebra. This edition contains additional material on secret codes, permutations, and prime numbers. It features more than 200 exercises, with many completely new. The text is organized into (...) relatively independent chapters, allowing instructors to tailor the book to meet their individual course needs. · Contains extra material concerning prime numbers, forming the basis for data encryption · Explores "Secret Codes" - one of today's most spectacular applications of pure mathematics Discusses Permutations and their importance in many topics in discrete mathematics.

The passing on of information to GPs by genito-urinary doctors is to be encouraged but is not always possible and ultimately the patient's wishes and confidentiality must be respected if sexually transmitted diseases and HIV infection are to be controlled. Infected health-care workers should seek counselling and medical support and clear guidelines from professional organisations which are in existence. However, they will only do so if strict confidentiality is maintained and assurance about future employment can be given.

This article conducts a normative evaluation of Operation Iraqi Freedom undertaken in 2003 by employing principles of prudence to enquire whether the use of force could be described as an action by a responsible great power. Along with relating the principles of prudence to the concept of great power responsibility, it highlights two pillars of prudent decision-making: circumspection and awareness of one's limits. This normative framework is then utilised to evaluate the invasion of Iraq from the perspective of these specific (...) aspects of prudence. The conclusion shows that on the basis of this normative yardstick, it is not possible to classify Operation Iraqi Freedom as a prudent action by a responsible great power. (shrink)

According to some, the combatant-noncombatant distinction has lost its relevance in today’s world. I examine two arguments to this effect. The first states that the distinction has become irrelevant when it categorizes children as combatants. I reply that the distinction has nothing to do with innocence or guilt, but with the degree to which a violent group poses a threat to others, even when it does so legitimately. The second argues that every civilian can be construed as a kind of (...) combatant, thus obliterating the distinction. My answer notes an error: states are representatives of citizens, not the other way around.My position in this paper is that individuals take on legitimate combatancy as a function of membership in an organization with legitimate combatancy. This paper attempts to construct a concept of the fighting organization that will allow us to determine the legitimate combatancy of such organizations. The three combatancy criteria I offer are military command structure, observance of the war convention, and representativeness. The first is a requirement for legitimate combatancy because it facilitates the prevention of ius in bello violations of the war convention and can enable the transition from war to diplomacy. My second criterion, the observance of the war convention, too, must be retained as a condition for legitimate combatancy: targeting noncombatants as a means of fighting the war certainly disqualifies organizations from potential POW status, and other ius in bello infractions might, as well. My third condition, representativeness, requires that fighters serve as moral proxies for a geographically contiguous, politically viable people in order to retain legitimate combatancy. If a fighting organization does not represent such a people, then it is a group of criminals rather than soldiers. (shrink)

The formulas-as-types isomorphism tells us that every proof and theorem, in the intuitionistic implicational logic $H_\rightarrow$, corresponds to a lambda term or combinator and its type. The algorithms of Bunder very efficiently find a lambda term inhabitant, if any, of any given type of $H_\rightarrow$ and of many of its subsystems. In most cases the search procedure has a simple bound based roughly on the length of the formula involved. Computer implementations of some of these procedures were done in Dekker. (...) In this paper we extend these methods to full classical propositional logic as well as to its various subsystems. This extension has partly been implemented by Oostdijk. (shrink)

In positive logic the negation of a propositionA is defined byA X whereX is some fixed proposition. A number of standard properties of negation, includingreductio ad absurdum, can then be proved, but not the law of noncontradiction so that this forms a paraconsistent logic. Various stronger paraconsistent logics are then generated by putting in particular propositions forX. These propositions range from true through contingent to false.

Precision Medicine has become a common label for data-intensive and patient-driven biomedical research. Its intended future is reflected in endeavours such as the Precision Medicine Initiative in the USA. This article addresses the question whether it is possible to discern a new ‘medical cosmology’ in Precision Medicine, a concept that was developed by Nicholas Jewson to describe comprehensive transformations involving various dimensions of biomedical knowledge and practice, such as vocabularies, the roles of patients and physicians and the conceptualisation of disease. (...) Subsequently, I will elaborate my assessment of the features of Precision Medicine with the help of Michel Foucault, by exploring how precision medicine involves a transformation along three axes: the axis of biomedical knowledge, of biomedical power and of the patient as a self. Patients are encouraged to become the managers of their own health status, while the medical domain is reframed as a data-sharing community, characterised by changing power relationships between providers and patients, producers and consumers. While the emerging Precision Medicine cosmology may surpass existing knowledge frameworks; it obscures previous traditions and reduces research-subjects to mere data. This in turn, means that the individual is both subjected to the neoliberal demand to share personal information, and at the same time has acquired the positive ‘right’ to become a member of the data-sharing community. The subject has to constantly negotiate the meaning of his or her data, which can either enable self-expression, or function as a commanding Superego. (shrink)

After presenting a variety of arguments in support of the idea that ordinary names are indexical, I respond to John Perry's recent arguments against the indexicality of names. I conclude by indicating some connections between the theory of names defended here and Wittgenstein's observations on naming, and suggest that the latter may have been misconstrued in the literature.
