Hagfishes have long held a key place in discussions of early vertebrate evolution. Frustratingly, one basis for such discussions—namely hagfish embryology—is very incompletely known, because the embryos of these animals are notoriously difficult to obtain.1,2 Fortunately, a recent publication on a Far Eastern hagfish3 describes a workable procedure for obtaining embryos and then uses this precious material to show that the hagfish neural crest arises by cell delamination as in other vertebrates—and not by epithelial outpouchings from the wall of the (...) neural tube as previously claimed.4 Importantly, because hagfish embryos should now be available on a regular basis, the way is open for additional morphological and developmental genetic investigations to help evaluate existing evolutionary scenarios and perhaps suggest new ones.

Recent advances in molecular biology and microanatomy have supported homologies of body parts between vertebrates and extant invertebrate chordates, thus providing insights into the body plan of the proximate ancestor of the vertebrates. For example, this ancestor probably had a relatively complex brain and a precursor of definitive neural crest. Additional insights into early vertebrate evolution have come from recent discoveries of Lower Cambrian soft body fossils of Haikouichthys and Myllokunmingia (almost certainly vertebrates, possibly related to modern lampreys) and Yunnanozoon (...) and Haikouella (evidently stem-group vertebrates). The earliest vertebrates had an unequivocally marine origin, probably evolved mineralised pharyngeal denticles before the dermal skeleton, and evidently utilised elastic recoil of the visceral arch skeleton for suction feeding. Moreover, the new data emphasise that the advent of definitive neural crest was supremely important for the evolutionary origin of the vertebrates.

In this posthumously published novel, Layers, Nathaniel Branden exhibits his talent as not only a philosopher and psychotherapist, but also a writer of fiction. The plot primarily involves the story of Nicholas Holland, a published author and leading therapist, as he interacts with Andrew Berringer, to whom he has come for therapy.

Based mainly on unpublished papers this is the first detailed study of the early, neo-Hegelian period of Bertrand Russell's career. It covers his philosophical education at Cambridge, his conversion to neo-Hegelianism, his ambitious plans for a neo-Hegelian dialectic of the sciences and the problems which ultimately led him to reject it.

This book advocates a radical shift of concern in philosophical, historical, and sociological studies of the sciences, and explores the consequences of such a shift. The historically-oriented first part of the work deals with the ways in which ranges of questions become real and cease to be real for communities of inquirers. The more philosophically-oriented second part of the work introduces the notion of absolute reality of questions, and addresses doubt about the claims of the sciences to have accumulated absolutely (...) real questions. It is argued that recent studies in the sociology and social history of the science pose strong challenges to the sciences by revealing how appeals to authority, vested interests, and rhetorical and aesthetic sensibilities play substantial roles in the practices of the sciences. The final chapter defends the pragmatic stance of the work, and of its companion, The Fortunes of Inquiry, and draws morals about the roles of criticism and reflection in the philosophy of science and in the sciences themselves.

The identity of conscious states and brain states must remain a mystery until we find a way of characterising both sides of the equation in terms that have the same ‘dimensions’. In this paper I stress the need for ‘dual currency concepts’ that not only are but can be seen to be as appropriate for talking about, say, the experience of pain as for talking about the corresponding working of the brain. In the light of evolutionary theory I make a (...) radically new proposal for what the common dimension is, centred on the idea of ‘authorship’. (shrink)

What is the evolutionary significance of the various mechanisms of imitation, emulation and social learning found in humans and other animals? This paper presents an advance in the theoretical resources for addressing that question, in the light of which standard approaches from the cultural evolution literature should be refocused. The central question is whether humans have an imitationbased inheritance system—a mechanism that has the evolutionary function of transmitting behavioural phenotypes reliably down the generations. To have the evolutionary power of an (...) inheritance system, an imitiation-based mechanism must meet a range of demanding requirements. The paper goes on to review the evidence for and against the hypothesis that there is indeed an imitation-based inheritance system in humans. (shrink)

This paper defends the idea that there might be vagueness or indeterminacy in the world itself---as opposed to merely in our representations of the world---against the charges of incoherence and unintelligibility. First we consider the idea that the world might contain vague *properties and relations*; we show that this idea is already implied by certain well-understood views concerning the semantics of vague predicates (most notably the fuzzy view). Next we consider the idea that the world might contain vague *objects*; we (...) argue that an object is indeterminate in a certain respect (colour, size, etc.) just in case it is a borderline case of a maximally specific colour (size, etc.) property. Finally we consider the idea that the *world as a whole* might be indeterminate; we argue that the world is indeterminate just in case it lacks a determinate division into determinate objects.

The Protagoras is one of Plato's most entertaining dialogues. It represents Socrates at a gathering of the most celebrated and highest-earning intellectuals of the day, among them the sophist Protagoras. In flamboyant displays of both rhetoric and dialectic, Socrates and Protagoras try to out-argue one another. Their arguments range widely, from political theory to literary criticism, from education to the nature of cowardice; but in view throughout this literary and philosophical masterpiece are the questions of what part knowledge plays in (...) a successful life, and how we may acquire the knowledge that makes for success. This edition contains the first commentary in English on the Greek text for almost a hundred years. The commentary provides the assistance with linguistic, literary and philosophical detail that will enable students and scholars to savour to the full the pleasures of the Protagoras. (shrink)

In the French presidential election, both candidates tried to keep their domestic life separate from their campaign. Ségolène Royal is not married to François Hollande, the father of her four children. When asked whether they were a couple, Royal replied, “Our lives belong to us.” Similarly, in response to rumors that President-elect Nicholas Sarkozy’s wife had left him, a spokesman for Sarkozy said, “That’s a private matter.” The French have a long tradition of respecting the privacy of their politicians’ (...) personal lives, and French public opinion is more broad-minded than in the United States, where an unwed mother of four would have no chance of being nominated for the presidency by a major party. Indeed, last month, Randall Tobias, the top foreign aid adviser in the US State Department, resigned after acknowledging that he had used an escort service described as providing “high-end erotic fantasy” – although Tobias said he only had a massage.

This edited collection presents the case for a research program (in Lakatos's sense) in the social sciences based on the theory of recognition developed by Axel Honneth and others in recent years. The cumulative argument of the book is that recognition theory provides both a plausible framework for explaining social conflict and a normative compass for reaching just resolutions.

The explosion of scientific results about epigenetic and other parental effects appears bewilderingly diverse. An important distinction helps to bring order to the data. Firstly, parents can detect adaptively-relevant information and transmit it to their offspring who rely on it to set a plastic phenotype adaptively. Secondly, adaptively-relevant information may be generated by a process of selection on a reliably transmitted parental effect. The distinction is particularly valuable in revealing two quite different ways in which human cultural transmission may operate.

For over 30 years I have argued, in and out of print that, for both intellectual and humanitarian reasons, we urgently need a revolution in the aims and methods of academic inquiry. Instead of giving priority to the search for knowledge, academia needs to devote itself to seeking and promoting wisdom by rational means, wisdom being the capacity to realize what is of value in life, for oneself and others. Wisdom thus includes knowledge but much else besides. A basic task (...) of academia would be to help humanity learn how to create a better world. Now I find the revolution is underway – entirely independent of my own efforts to promote it. During the last ten to twenty years, all sorts of changes have taken place in academia that amount to putting aspects of wisdom-inquiry into practice – even if in complete ignorance of my work. Perhaps the most significant steps are the creation of departments, institutions and research centres concerned with social policy, with problems of environmental degradation, climate change, poverty, injustice and war, and with such matters as medical ethics and community health. Nevertheless, the revolution is happening with agonizing slowness, in a dreadfully muddled and piecemeal way. It needs academics and non-academics to wake up to what is going on – or what needs to go on – to help give direction, coherence and a rationale to this nascent revolution from knowledge to wisdom.

Mankind as a species has little reason to boast about his sensory capacities. A dog's sense of smell, a bat's hearing, a hawk's visual acuity are all superior to our own. But in one respect we may justifiably be vain: our ability to see colours is a match for any other animal. In this respect we have in fact surprisingly few rivals. Among mammals only our nearest relatives, the monkeys and apes, share our ability – all others are nearly or (...) completely colour-blind. In the animal kingdom as a whole colour vision occurs only in some fishes, reptiles, insects and birds. (shrink)

At the opening of the twenty-first century, while obviously the world is still struggling with violence and conflict, many commentators argue that there are many reasons for supposing that restrictions on the use of force are growing. The establishment of the International Criminal Court, the growing sophistication of international humanitarian law and the 'rebirth' of the just war tradition over the last fifty years are all taken as signs of this trend. This book argues that, on the contrary, the just (...) war tradition, allied to a historically powerful and increasingly dominant conception of politics in general, is complicit with an expansion of the grounds of supposedly legitimate force, rather than a restriction of it. In offering a critique of this trajectory, 'Just War and International Order' also seeks to illuminate a worrying trend for international order more generally and consider what, if any, alternative there might be to it.

-/- Following the Mental Capacity Act (MCA) becoming law in 2005, and prior to its coming into force in 2007, there was a sustained effort to train support staff in the many social care settings where this new law was applicable. This training drive was necessary because, prior to the MCA, mental capacity law had evolved in the courts through consideration of a small number of cases that concerned serious medical treatments. These included the withdrawal of artificial nutrition and hydration (...) (Airedale NHS Trust v. Bland [1993]), blood transfusion (Re T [1993]), tissue donation (Re Y [1997]) and the provision of experimental medication for terminal illness (Simms v. Simms and another (2003)). In line with the Law Commission’s recommendations, the MCA extended the application of the law to ‘all acts in connection with care or treatment’ (MCA, Section 5), meaning that, overnight, social care settings and informal family care environments immediately fell within the scope of the legislation.

Two great problems of learning confront humanity: learning about the universe, and learning how to live wisely. The first problem was solved with the creation of modern science, but the second problem has not been solved. This combination puts humanity into a situation of unprecedented danger. In order to solve the second problem we need to learn from our solution to the first problem. This requires that we bring about a revolution in the overall aims and methods of academic inquiry, (...) so that it takes up its proper task of promoting wisdom. (shrink)
