Introspection, or metacognition, is the capacity to reflect on our own thoughts and behaviours. Here, we investigated how one specific metacognitive ability develops in adolescence, a period of life associated with the emergence of self-concept and enhanced self-awareness. We employed a task that dissociates objective performance on a visual task from metacognitive ability in a group of 56 participants aged between 11 and 41 years. Metacognitive ability improved significantly with age during adolescence, was highest in late adolescence and plateaued going (...) into adulthood. Our results suggest that awareness of one’s own perceptual decisions shows a prolonged developmental trajectory during adolescence. (shrink)

At the forefront of international concerns about global legislation and regulation, a host of noted environmentalists and business ethicists examine ethical issues in consumption from the points of view of environmental sustainability, economic development, and free enterprise.

Many extant theories of placebo focus on their causal structure wherein placebo effects are those that originate from select features of the therapy (e.g., client expectations or “incidental” features like size and shape). Although such accounts can distinguish placebos from standard medical treatments, they cannot distinguish placebos from everyday occurrences, for example, when positive feedback improves our performance on a task. Providing a social-epistemological account of a treatment context can rule out such occurrences, and furthermore reveal a new way to (...) distinguish clinical placebos from standard medical treatments.

Does exploration of the gut microbiota–brain axis expand our understanding of what it means to be human? Recognition and conceptualization of a gut microbiota–brain axis challenges our study of the nervous system. Here, integrating gut microbiota–brain research into the metaorganism model is proposed. The metaorganism—an expanded, dynamic unit comprising the host and commensal organisms—asserts a radical blurring between man and microbe. The metaorganism nervous system interacts with the exterior world through microbial‐colored lenses. Ongoing studies have reported that gut microbes contribute (...) to brain function and pathologies, even shaping higher neurological functions. How will continued collaborative efforts (e.g., between neurobiology and microbiology), including partnerships with the arts (e.g., philosophy), contribute to the knowledge of microbe‐to‐mind interactions? While this is not a systemic review, this nascent field is briefly described, highlighting ongoing challenges and recommendations for emerging gut microbiota–brain research.

On a version of consent theory that tempts many, predatory sexual relations involving significant power imbalances (e.g. between professors and students, adults and teenagers, or employers and employees) are wrong because they violate consent-centric norms. In particular, the wronged party is said to have been _incapable_ of consenting to the predation, and the sexual wrong is located in the encounter’s nonconsensuality. Although we agree that these are sexual wrongs, we resist the idea that they are always nonconsensual. We argue instead (...) that it is possible for students, teenagers, employees, etc. to fully consent to sexually predatory encounters; denying as much renders survivors of predation vulnerable to compounding harms. Survivors face a dilemma: give up either their understanding of their experience as wrong, or their self-conception as an agent capable of consenting. We call the latter phenomenon _agential demotion_. (shrink)

Disclosure in clinical practice is aimed at promoting patient autonomy, usually culminating in patient choice (e.g., to consent to an operation or not, or between different medications). In medical ethics, there is an implicit background assumption that knowing more about (X) automatically translates to greater, or more genuine, autonomy with respect to one's choices involving (X). I challenge this assumption by arguing that in rare cases, withholding information can promote a patient's autonomy (understood as the capacity for rational choice in (...) alignment with one's values and goals).

Throughout the twentieth century, moral philosophers have done their best to push the question of moral change off the intellectual agenda. If you look back to Principia Ethica, which appeared in 1903, you will find G.E. Moore taking it for granted that ethics is concerned with a single unanalysable object called “the good”, which is the only thing we can ever really mean when we talk about “goodness”. There could be no progress in morality as such, apart from throwing out (...) any historical flotsam and jetsam that might have made its way into the clear waters of ethical intuition. Genuine ethics did not have a history, in Moore’s opinion; only pseudo-ethics did. (shrink)

Is the history of philosophy a complex history of errors? That, according to Jonathan Rée, author of the first of three essays that comprise this book, is the prevailing sentiment of contemporary philosophy, which tends to perceive the history of philosophy as a "diversion from real philosophical activity." That sentiment, Rée argues, is the by-product of a failure of the history of philosophy itself, the "unhistorical history of philosophy." Rée maintains that the nature of philosophical history is determined by concepts (...) employed by the history of philosophy. Histories of philosophy have characteristically tended to locate a number of "eternally available and unchanging" positions to which philosophers are said to have ascribed with which they engage other philosophers "as though they were participants at a modern philosophy conference." Because it fails to "involve some conception of history," the "orthodox History of Philosophy is a fabric of illusions and distortions.". (shrink)

This volume brings together J.S. Mills On Liberty and a selection of important essays by such eminent scholars as Isaiah Berlin, Alan Ryan, John Rees, C.L. Ten and Richard Wollheim. As well as providing authoritative commentary upon On Liberty , the essays reflect a broader debate about the philosophical foundations of Mill's liberalism, particularly the question of the connection betweenMill's professed utilitarianism and his commitment to individual liberty. Introduced and edited by John Gray and G.W. Smith, the book will (...) be of interest to students of Mill, to ethical and political philosophers and to anyone interested in the contemporary status of liberalism. (shrink)

In How We Get Along, J. David Velleman argues for two related theses: first, that ‘making sense’ of oneself to oneself and others is a constitutive aim of action; second, that this fact about action grounds normativity. Examining each thesis in turn, I argue against the first that an agent may deliberately act in ways which make sense in terms of neither her self-conception nor others' conceptions of her. Against the second thesis, I argue that some vices are such that (...) the agents concerned would make more sense to neither themselves nor others if they were to reform, and, furthermore, that an agent may make more sense to herself and others by becoming more, rather than less, vicious. I conclude that both theses should be rejected. (shrink)
