This paper examines social network size in contemporary Western society based on the exchange of Christmas cards. Maximum network size averaged 153.5 individuals, with a mean network size of 124.9 for those individuals explicitly contacted; these values are remarkably close to the group size of 150 predicted for humans on the basis of the size of their neocortex. Age, household type, and the relationship to the individual influence network structure, although the proportion of kin remained relatively constant at around 21%. (...) Frequency of contact between network members was primarily determined by two classes of variable: passive factors (distance, work colleague, overseas) and active factors (emotional closeness, genetic relatedness). Controlling for the influence of passive factors on contact rates allowed the hierarchical structure of human social groups to be delimited. These findings suggest that there may be cognitive constraints on network size. (shrink)

Discussions of responsibility typically focus on the person who is held responsible: what are the conditions or criteria of responsibility; what can be done to or demanded of a person who is responsible? This paper shifts focus onto those who hold, rather than those who are held, responsible: what do we owe to those whom we hold responsible? After distinguishing responsibility as answerability from responsibility as liability, it attends mainly to the former, and points out the ways in which it (...) is multiply relational: I am responsible for something to someone who has the standing to call me to account for it, under the norms of some particular practice. Responsibility as thus understood is also reciprocal: if you are to be answerable to me, I must treat you with a certain respect, attend seriously to your answer, and be ready to answer to you myself. The paper explores some of the implications of this point both for our moral dealings with each other, and for criminal law and the criminal trial. (shrink)

The literature fails to reflect general agreement over the nature of the services and procedures provided by bioethicists, and the training and core competencies this work requires. If bioethicists are to define their activities in a consistent way, it makes sense to look for common ground in shared communities of practice. We report results of a survey of the services and procedures among bioethicists affiliated with the University of Toronto Joint Centre for Bioethics (JCB). This is the largest group of (...) bioethicists working in healthcare organizations in Canada. The results suggest there are many common services and procedures of JCB bioethicists. This survey can serve as a baseline for further exploration of the work of JCB bioethicists. Common practices exist with respect to the domains of practice, individual reporting relationships, service availability within business hours and the education and training of the bioethicist.

Study of Samayasāra, treatise on Jaina philosophy by Kundakunda.

Two treatises on memory which have come down to us from antiquity are Aristotle’s “On memory and recollection” and Plotinus’ “On perception and memory” ; the latter also wrote at length about memory in his “Problems connected with the soul”. In both authors memory is treated as a ‘modest’ faculty: both authors assume the existence of a persistent subject to whom memory belongs; and basic cognitive capacities are assumed on which memory depends. In particular, both theories use phantasia to explain (...) memory. Aristotle takes representations to be changes in concrete living things which arise from actual perception. To be connected to the original perception the representation has to be taken as a copy of the original experience ‑ this is the way Aristotle defines memory at the end of his investigation. Plotinus does not define memory: he is concerned with the question of what remembers. This is of course the soul, which goes through different stages of incarnation and disincarnation. Since the disembodied soul can remember, so he does not have Aristotle’s resources for explaining the continued presence of representations as changes in the concrete thing. Instead, he thinks that when acquiring a memory we acquire a capacity in respect of the object of the memory, namely to make it present at a later time. (shrink)

The discovery of the microworld presented a serious trial for many systems of views held by mankind, including its logic. This world was found to lack the familiar solid bodies, the unchanging particles and interrelations between them, the reflection of which, in one way or another, is the logic of the macroscopic world. What elementary particle physics encountered in the microscopic world seemed illogical: the rest-mass of a particle equals zero; a part that is not smaller than the whole; a (...) particle that in diffraction experiments moved like a wave; and much else that was unusual and strange in the properties of elementary particles. One of these properties was actually so named by physicists — "strangeness.". (shrink)

Working memory--the ability to keep important information in mind while comprehending, thinking, and acting--varies considerably from person to person and changes dramatically during each person's life. Understanding such individual and developmental differences is crucial because working memory is a major contributor to general intellectual functioning. This volume offers a state-of-the-art, integrative, and comprehensive approach to understanding variation in working memory by presenting explicit, detailed comparisons of the leading theories. It incorporates views from the different research groups that operate on each (...) side of the Atlantic, and covers working-memory research on a wide variety of populations, including healthy adults, children with and without learning difficulties, older adults, and adults and children with neurological disorders. A particular strength of this volume is that each research group explicitly addresses the same set of theoretical questions, from the perspective of both their own theoretical and experimental work and from the perspective of relevant alternative approaches. Through these questions, each research group considers their overarching theory of working memory, specifies the critical sources of working memory variation according to their theory, reflects on the compatibility of their approach with other approaches, and assesses their contribution to general working memory theory. This shared focus across chapters unifies the volume and highlights the similarities and differences among the various theories. Each chapter includes both a summary of research positions and a detailed discussion of each position. Variation in Working Memory achieves coherence across its chapters, while presenting the entire range of current theoretical and experimental approaches to variation in working memory. (shrink)

Epistemic decision theorists aim to justify Bayesian norms by arguing that these norms further the goal of epistemic accuracy—having beliefs that are as close as possible to the truth. The standard defense of Probabilism appeals to accuracy dominance: for every belief state that violates the probability calculus, there is some probabilistic belief state that is more accurate, come what may. The standard defense of Conditionalization, on the other hand, appeals to expected accuracy: before the evidence is in, one should expect (...) to do better by conditionalizing than by following any other rule. We present a new argument for Conditionalization that appeals to accuracy‐dominance, rather than expected accuracy. Our argument suggests that Conditionalization is a rule of coherence: plans that conflict with Conditionalization don't just prescribe bad responses to the evidence; they also give rise to inconsistent attitudes.

In Menciusiia6 all humans are said to have ‘a heart that does not bear the suffering of others’. I argue that this statement is illustrated, rather than proven, by the example of our reaction to a child about to fall into a well. This illustration can be located at the most basic level of ethical universals : basic ethical training; further steps in a ladder of reflection are universal reflection on ethical norms themselves, which may finally be related universally to (...) non‐ethical concerns.
