Quantum physics is believed to be the fundamental theory underlying our understanding of the physical universe. However, it is based on concepts and principles that have always been difficult to understand and controversial in their interpretation. This book aims to explain these issues using a minimum of technical language and mathematics. After a brief introduction to the ideas of quantum physics, the problems of interpretation are identified and explained. The rest of the book surveys, describes and criticises a range of (...) suggestions that have been made with the aim of resolving these problems; these include the traditional, or 'Copenhagen' interpretation, the possible role of the conscious mind in measurement, and the postulate of parallel universes. This new edition has been revised throughout to take into account developments in this field over the past fifteen years, including the idea of 'consistent histories' to which a completely new chapter is devoted.

Group size is a function of relative neocortical volume in nonhuman primates. Extrapolation from this regression equation yields a predicted group size for modern humans very similar to that of certain hunter-gatherer and traditional horticulturalist societies. Groups of similar size are also found in other large-scale forms of contemporary and historical society. Among primates, the cohesion of groups is maintained by social grooming; the time devoted to social grooming is linearly related to group size among the Old World monkeys and (...) apes. To maintain the stability of the large groups characteristic of humans by grooming alone would place intolerable demands on time budgets. It is suggested that (1) the evolution of large groups in the human lineage depended on the development of a more efficient method for time-sharing the processes of social bonding and that (2) language uniquely fulfills this requirement. Data on the size of conversational and other small interacting groups of humans are in line with the predictions for the relative efficiency of conversation compared to grooming as a bonding process. Analysis of a sample of human conversations shows that about 60% of time is spent gossiping about relationships and personal experiences. It is suggested that language evolved to allow individuals to learn about the behavioural characteristics of other group members more rapidly than is possible by direct observation alone. (shrink)

In his discussion of the tragic act in Poet. 14. 1453b15 ff. Aristotle separates the pity which we feel at mere suffering from pity roused by the way in which this suffering is or will be brought about. The revenge of an enemy is not in itself pitiable. We pity, if victim and agent are closely related to one another as members of the same family, but only if the action is of a certain kind. Four possible ways of presenting (...) the tragic act are therefore distinguished: attempted but not performed, with knowledge of the relevant facts ; performed with knowledge ; performed but in ignorance, recognition following later ; attempted in ignorance but not performed, since recognition occurs in time to prevent it. Of these four variations the first is censured on the ground that it is morally shocking without being tragic, since it lacks πάθος. The second is mentioned in b27 as the favourite of the older poets, but is here passed over without comment. The third is explicitly approved on the ground that it avoids moral shock and has the emotional κπληξις of the recognition. But for some reason which he does not state, Aristotle prefers the last, where recognition is in time to prevent the tragic suffering from actually taking place. (shrink)

Purpose. The study seeks to clarify the preconditions for moral and legal decision-making based on the identification of axiological foundations that correlate with the moral perceptions of good and evil and psychological phenomena such as emotions. Theoretical basis of the study is to apply comparative, axiological, systemic methods. This methodological approach allows us to analyze and disclose the essence of the process of moral and legal decision-making on the basis of certain axiological prerequisites and enables to substantiate the connection between (...) the axiological and psychological aspects of taking moral and legal decisions. Originality of the work is to broaden the perceptions of the processes and mechanisms for making moral and legal decisions, which are based on the axiological dimension, in particular on the system of reference individual and social values. The study shows that every necessary moral and legal decision taken by a person is futurologically balanced in the emotional sense, rationally reasoned and morally perceptible in the context of man’s beliefs about good and evil, and realized with necessity in the personal system of reference values that determines the style and manner of individual and social behaviour in the context of material and spiritual values and is an axiological foundation for making all types of moral and legal decisions. Conclusions. Moral and legal decision-making is a social process that is connected with such a social essence of a person as rationality, which gives an opportunity to act axiologically. A person makes moral and legal decisions in a complex way, based on the unity of the moral, axiological and psychological aspects of his worldview, which are grounded on the system of reference values.
