A global target of stabilizing greenhouse-gas concentrations at between 450 and 550 parts per million carbon-dioxide equivalent has proven robust to recent developments in the science and economics of climate change. Retrospective analysis of the Stern Review suggests that the risks were underestimated, indicating a stabilization target closer to 450 ppm CO2e. Climate policy at the international level is now moving rapidly towards agreeing an emissions pathway, and distributing responsibilities between countries. A feasible framework can be constructed in which each (...) country takes on its own responsibilities and targets, based on a shared understanding of the risks and the need for action and collaboration on climate change. The global deal should contain six key features: a pathway to achieve the world target of 50 per cent reductions by 2050, where rich countries contribute at least 75 per cent of the reductions; global emissions trading to reduce costs; reform of the clean development mechanism to scale up emission reductions on a sectoral or benchmark level; scaling up of R&D funding for low-carbon energy; an agreement on deforestation; and adaptation finance.

Multiple -conclusion logic extends formal logic by allowing arguments to have a set of conclusions instead of a single one, the truth lying somewhere among the conclusions if all the premises are true. The extension opens up interesting possibilities based on the symmetry between premises and conclusions, and can also be used to throw fresh light on the conventional logic and its limitations. This is a sustained study of the subject and is certain to stimulate further research. Part I reworks (...) the fundamental ideas of logic to take account of multiple conclusions, and investigates the connections between multiple - and single - conclusion calculi. Part II draws on graph theory to discuss the form and validity of arguments independently of particular logical systems. Part III contrasts the multiple - and the single - conclusion treatment of one and the same subject, using many-valued logic as the example; and Part IV shows how the methods of 'natural deduction' can be matched by direct proofs using multiple conclusions.

This article aims at linking empirical research to legal theories, in a way that could enhance the benefits of this synergy. Jurisprudence, until recently the usual term for theoretical approaches to law, is now often replaced by the term legal theory. Difference between legal theory and empirical research is reflected in their consideration of subject matters, aims, and methods of research. However, there also exist commonalities between the two, i.e. both aim at comprehending law and legal systems. While legal theory (...) uses philosophical tools, its subject matter still remains a social phenomenon, for social ends. And since empirical research is a means to gather information about law, it could act as a prime source of information for legal theory. While empirical research has its own end to follow, what is missing is, attention to some legal theory, not just general legal theory, but which can also critique philosophical discourses to legality.

Does South Africa need a common moral language? Many people are of the opinion that South Africa finds itself 'after Babel’ and needs a common moral language (1). The author considers some of the arguments of people who disagree with this analysis, because they do not define the problem in this way (2); because they find the language- or Babel-methaphor confusing (3); because they agree with the description of the problem, but not with the suggested solution, namely a common moral (...) language (4); or because they accept the solution, but do not regard it as the proper task of the Christian church to be involved in this search for a common moral language (5).

I present an annotated development of the basic ideas of the Geneva School approach to the foundations of physics and the structures which emerge as mathematical representations of the physically dual notions of state and property.

" Waldie speculates on the meanings and implications of the snapshots in this book and of snapshots generally, which he sees as expressions of "the hunger of memory.".

The present state of the law is unsatisfactory. The exact effect on the marriage of the parties has not been decided although in English law if artificial insemination by donor (AID) takes place without consent that would appear to be a ground for divorce since 1969. The law regards a child born as a result of AID as illegitimate and draws no distinction between the case where the husband consents and where he does not. Theoretically, an offence is committed if (...) the birth entry is falsified, presumably in cases where the husband consents. The AID child, like any other illegitimate child, has rights against the natural parents, but he is in a worse position than most illegitimate children, in that he may not have any information about his father. It is now possible to freeze sperm and so preserve it over longer periods. All the problems associated with AID are present also when sperm is preserved in banks, but if the law is in an unsatisfactory state in relation to AID this is even more true in relation to sperm banks. The main criticism of the Feversham Report (1960) could be that it recommended, broadly speaking, the `status quo' but scientific progress has now overtaken and left the Feversham findings well behind. What, therefore, is required is a full consideration of the subject of AID and, on the basis of that, some statutory code regulating all its aspects. (shrink)

Do the most celebrated works of Rousseau—more particularly his Discourse on Inequality, émile , and Control Social —present on the whole a coherent answer to the problems of Education and Society? My impression is that Rousseau has here been very much calumniated, owing to the incredible haste and superficiality with which his writings have generally been studied. Even sympathetic inquirers, like M. Schinz in his thorough and attractive work La Pensée de J. J. Rousseau , seem to be too easily (...) discouraged in the quest for unity. (shrink)

Ovid begins his overtly programmatic Amores 2.1 with the claim that Cupid, who had previously interfered with the poet's attempt to write an epic , has once again ordered him to reject epic subjects and to compose a book of decadent love-elegies instead. Faced with this new task, the poet dutifully proceeds to warn that his elegiac verses are not suitable for the prudish but hopes that they will be read by lovers. Among the prospective readers are young men who, (...) like Ovid himself, have been shot by Cupid's arrow. (shrink)
