Originally published in 1981. This is a book for the final year undergraduate or first year graduate who intends to proceed with serious research in philosophical logic. It will be welcomed by both lecturers and students for its careful consideration of main themes ranging from Gricean accounts of meaning to two dimensional modal logic. The first part of the book is concerned with the nature of the semantic theorist's project, and particularly with the crucial concepts of meaning, truth, and semantic structure. The second and third parts deal with various constructions that are found in natural languages: names, quantifiers, definite descriptions, and modal operators. Throughout, while assuming some familiarity with philosophical logic and elementary formal logic, the text provides a clear exposition. It brings together related ideas, and in some places refines and improves upon existing accounts.

During the first UK wave of the pandemic, there were two areas of immediate ethical concern for the medical profession. The first was the possibility that life-saving resources could be overwhelmed. Early reports from hospitals in the Italian city of Bergamo suggested that ventilatory support might need rationing and emergency ‘battlefield’ triage was a real possibility.1 In the UK, several professional bodies, including the British Medical Association and the Royal College of Physicians rapidly developed guidance for doctors should triage become a reality.2 The second issue was the acute shortage of personal protective equipment. Where doctors were unable to protect their patients – and themselves – from the risk of COVID-19, ethical challenges emerged. Ordinarily, doctors and patients do not present risks of significant harm to each other. To shift to a position where every patient – and every health professional – could potentially be a threat presented serious clinical and ethical challenges. To treat with inadequate PPE, so options for mitigating harms are radically reduced, deepens the challenges. Among the questions the BMA wrestled with was the extent of doctors’ duties to treat infected or potentially infected patients in the absence of effective PPE. The BMA was clear that despite obligations to treat, medicine is not a self-sacrificing profession: there were limits to the risk doctors could be required to expose themselves to.3 These issues no longer seem so pressing. In the UK at least, there is adequate PPE and with the second steep wave behind us, and significant numbers vaccinated, it is less likely that triage will be required in the UK. But as those concerns have receded so other ethical questions have arisen. Among them is a cluster of issues associated with what might be called COVID-19’s indirect harms. Understandably, in response to …

A simple experimental paradigm creates the powerful illusion that one is touching one’s own hand even when the two hands are separated by 15 cm. The participant uses her right hand to administer stimulation to a prosthetic hand while the Examiner provides identical stimulation to the participant’s receptive left hand. Change in felt position of the receptive hand toward the prosthetic hand has previously led to the interpretation that the participant experiences self-touch at the location of the prosthetic hand, and experiences a sense of ownership of the prosthetic hand. Our results argue against this interpretation. We assessed change in felt position of the participant’s receptive hand but we also assessed change in felt position of the participant’s administering hand. Change in felt position of the administering hand was significantly greater than change in felt position of the receptive hand. Implications for theories of ownership are discussed.

In August, Amnesty International and the World Medical Association expressed concern at reports that a judge in Saudi Arabia had asked several hospitals in the country whether they could perform an operation to damage a man's spinal cord as punishment for attacking another man and leaving him paralysed. The man had already been sentenced to seven months imprisonment for the crime, the injured victim requested the further sentence under Sharia Law, which is strictly enforced across Saudi Arabia. According to reports, one of the hospitals approached declined on ethical grounds. Another hospital stated that it was possible to damage the spinal cord in the way requested, but that the procedure would have to be done at a specialised hospital. 1In its statement, Amnesty International urged the authorities not to carry out the sentence, which it argued would be a grave violation of international human rights law and contravene the United Nations convention against Torture, to which Saudi Arabia is a state party. 2 The WMA expressed its support for the physicians who refused to carry out the request by the Saudi court, participation in which would constitute a severe breach of medical ethics. 3 The WMA reminded doctors that the Declaration of Tokyo clearly states that no physician should participate in the practice of torture or any other forms of cruel, inhuman or degrading procedures, whatever the offence of which the victim of such procedures is suspected, accused or guilty of. The Declaration also includes a prohibition of participation in the planning or advising for such a procedure.

Glyn Humphreys' research on attention and binding began from feature‐integration theory, which claims that binding together visual features, such as colour and orientation, requires spatially selective attention. Humphreys employed a more inclusive notion of binding and argued, on neuropsychological grounds, for a multi‐stage account of the overall binding process, in which binding together of form elements was followed by two stages of feature binding. Only the second stage of feature binding, a re‐entrant (top‐down) process beginning in posterior parietal cortex and returning to early visual areas, required attention. In line with his commitment to converging evidence, Humphreys considered that investigating the role of attention in motion‐induced blindness could be a route to better understanding of the cognitive role of the attention‐dependent second stage of feature binding. He suggested that this role might be to resolve ambiguity and to generate a single consistent interpretation of the perceptual input.

Thinking about the Enlightenmentlooks beyond the current parameters of studying the Enlightenment, to the issues that can be understood by reflecting on the period in a broader context. Each of the thirteen original chapters, by an international and interdisciplinary team of contributors, illustrates the problematic legacy of the Enlightenment and the continued ramifications of its thinking since the eighteenth century. Together, they consider whether modernity can see its roots in the intellectual revolution of the seventeenth and eighteenth centuries. The collection is divided into six sections, preceded by a comprehensive introduction to the field and the most recent scholarship on the period. Across the sections, the contributors consider modern day encounters with Enlightenment thinking, including Kant's moral philosophy, the conflict between reason and faith, the significance of the Enlightenment of law and the gender inequality that persisted throughout the eighteenth century. By examining specific encounters with the problematic results of Enlightenment concerns, the contributors are able to illuminate and offer new perspectives on topics such as human nature, race, politics, gender and rationality. Drawing from history, philosophy, literature and anthropology, this book enables students and academics alike to take a fresh look at the Enlightenment and its legacy in the modern world.

At the time of writing the COVID-19 pandemic was entering its ninth month, with nearly 800 000 recorded fatalities and 22 million infections in 188 countries and territories.1 In previous ethics briefings2 we raised concerns about the possibility that demand for life-sustaining treatment would overwhelm supply, with a consequent requirement for health professionals to make challenging triage decisions. Fortunately, to date, these have largely not been realised, although there is a possibility that countries in which containment measures have been less-successful, such as South Africa, may still be required to triage.3 Despite the successful ‘flattening of the curve’ in many countries, there is a wide consensus that we remain firmly within the pandemic. Enormous practical challenges remain. It is unclear whether the pandemic will ultimately take the form of two or more successive waves, or whether the patchwork of global responses will lead to a sustained slow ‘burn’ with sporadic flare-ups.4 Areas of uncertainty include whether infection confers some immunity, how long any such immunity might last, whether effective vaccines can be developed and if seasonal temperature fluctuations alter the spread of the virus. The pandemic will also be fundamentally shaped by the decisions that governments make and the extent to which their diktats are complied with by citizens. With the – possibly temporary – retreat of urgent clinical ethics issues, such as triage, opportunities have arisen to reflect on some of the ethical questions that underlie and structure the demanding policy decisions that governments are wrestling with. One of the early questions was how to balance the complex constellation of costs and benefits associated with lockdown. Countries that …

Proponents of fetal rights argue that, from the moment of conception, a fetus has significant human rights. There are degrees of opinion, however, about the scope of those rights, with some arguing that, in certain circumstances, such as where the conception is the result of rape, the mother's rights predominate. Others argue that the fetus' rights are absolute and should override the woman's right to life and health so that pregnancies cannot be terminated, even to save women's lives. Various countries explicitly or implicitly recognise the status of the fetus as a separate person with varying degrees of rights. For example, the Irish Constitution recognises the ‘right to life of the unborn’ and the 2004 US Unborn Victims of Violence Act views violence against a pregnant woman as a crime against two people, one of whom is the child in utero. The 1969 American Convention on Human Rights has been signed by most Latin American countries and recognises full human rights as applying from conception. In the UK, the fetus has no legal rights but it is widely agreed that the closer a fetus is to being capable of independent existence outside the womb, the greater the moral obligations owed to it. This is reflected in the abortion law only permitting termination of a pregnancy at the later stages in restricted circumstances.In Brazil, the issue of fetal rights was highlighted in May 2010 when a Bill was put forward which aimed to give the fetus priority in law and to make illegal any act or omission that could have a negative impact on it. The bill proposes that the family, society and the …
