R.I.G. Hughes presents a series of eight philosophical essays on the theoretical practices of physics. The first two essays examine these practices as they appear in physicists' treatises (e.g. Newton's Principia and Opticks ) and journal articles (by Einstein, Bohm and Pines, Aharonov and Bohm). By treating these publications as texts, Hughes casts the philosopher of science in the role of critic. This premise guides the following 6 essays which deal with various concerns of philosophy of physics such as laws, (...) disunities, models and representation, computer simulation, explanation, and the discourse of physics.

R.I.G Hughes offers the first detailed and accessible analysis of the Hilbert-space models used in quantum theory and explains why they are so successful.

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)

Data from various settings suggest that there is an upper limit of about four on the number of individuals who can interact in spontaneous conversation. This limit appears to be a consequence of the mechanisms of speech production and detection. There appear to be no differences between men and women in this respect, other than those introduced by women’s lighter voices.

Data on the number of adults that an individual contacts at least once a month in a set of British populations yield estimates of network sizes that correspond closely to those of the typical “sympathy group” size in humans. Men and women do not differ in their total network size, but women have more females and more kin in their networks than men do. Kin account for a significantly higher proportion of network members than would be expected by chance. The (...) number of kin in the network increases in proportion to the size of the family; as a result, people from large families have proportionately fewer non-kin in their networks, suggesting that there is either a time constraint or a cognitive constraint on network size. A small inner clique of the network functions as a support group from whom an individual is particularly likely to seek advice or assistance in time of need. Kin do not account for a significantly higher proportion of the support clique than they do for the wider network of regular social contacts for either men or women, but each sex exhibits a strong preference for members of their own sex.

It is shown that a formula of modal propositional logic has precisely the same models as a sentence of the first-order language of a single dyadic predicate iff its class of models is closed under ultraproducts. as a corollary, any modal formula definable by a set of first-order conditions is always definable by a single such condition. these results are then used to show that the formula (lmp 'validates' mlp) is not first-order definable.

Science and religion have been described as the “two dominant forces in our culture”. As such, the relation between them has been a matter of intense debate, having profound implications for deeper understanding of our place in the universe. One position naturally associated with scientists of a materialistic outlook is that science and religion are contradictory, incompatible worldviews; however, a great deal of recent literature criticises this “conflict thesis” as simple-minded, essentially ignorant of the nature of religion and its philosophical (...) and theological underpinnings. In this first part of a two-part article, I set out the wide-ranging background required for a proper understanding of the debate as a preliminary for the second part, in which Ian Barbour ’s influential four-fold typology of science-religion relations is critically assessed, leading to the conclusion that the conflict model is not to be so easily dismissed.

During the second half of the XX century drug addiction ceased to be only the epiphenomenon of crime, prostitution and a number of other social-relations deviation, and became a constant value of post-industrial society and at the end of XX century turned into a global problem of mankind. A new form of mass neurosis shows that drug dependence is nowadays socially conditioned mental degeneration, caused by activation of unconscious collective archetypes that are experienced depending on the corresponding situation. The identification (...) of the sacred plant soma/haoma with the marihuana enables us to not only to make clear the light and the dark sides of this archetype, but also to figure out that the reduction of the drug addiction problem, to the acceptable for the society level, is possible only if a man will be able to satisfy his “life-asserting, vital needs”, if he will be able to regain the true meaning of life.

This volume of recent writings, some previously unpublished, follows the sequence of a typical intermediate or upper-level logic course and allows teachers to enrich their presentations of formal methods and results with readings on corresponding questions in philosophical logic.

There can be no doubt that we do know one another. We know that others exist and we know a good deal about others. The question is how we know others. To say that others do not exist would be to assert a solipsism—a theory which no serious philosopher has ever maintained. Solipsism is absurd. Not because it is self-contradictory, for there is nothing self-contradictory in the notion that I alone exist having the experiences and thoughts which I do have (...) and that apart from me nothing and no one else exists. It is absurd simply because others do exist and I know this; because, that is to say, it contradicts the known evidence. This is the sole—but the adequate—ground for concluding solipsism to be absurd. Any discussion of this present problem, therefore, must begin with, the recognition of the fact that knowledge of others occurs. (shrink)

John Searle attempts to show through a consideration of promising that at least some ‘ought’ statements can be derived from ‘is’ statements. He thinks that you can determine on purely factual grounds that a person has made a promise, and that it follows logically from the statement that a person has made a promise that he has at least a prima facie obligation to do the thing he promised to do. I agree with but not with.

Locke is the first English philosopher to be considered in this series, and that fact of itself is worthy of attention. Philosophy, of course, like science, knows no frontiers and no national boundaries. Yet it is true to say that Locke’s contribution to philosophy is typically and peculiarly English. His moderation, his emphasis upon experience, his tolerant spirit of compromise, his dislike of mystical extravagance and of metaphysical speculation, even that elusive quality of his which people call his “common sense”, (...) are English traits. His very defects, illogicality leading to inconsistency and an awkward disorderliness of thought so abhorrent to the. (shrink)

The urgency of the research topic is that the attempt, through the prism of higher education in Ukraine, is to outline the factors and opportunities for forming a positive image of a modern teacher as the basis for the competitiveness of a higher educational institution. The purpose of the article is: rethinking the teacher’s image in conditions of growing demands and increasing competitiveness among higher education institutions. The objectives of the study are to summarize the data of the investigated problem (...) and to develop a model for the development of theoretical aspects of forming a teacher’s positive image in the context of the growth of the status of the university, and an analysis of the interdependence of the teacher’s image and his professional competence, practical skills, and the ability to associate theory with practice. The research methodology is general scientific and special-disciplinary methods of scientific research. In particular, the methods of theoretical generalization, analogy and abstraction are used to clarify the conditions, specifics and realities of the modern educational process, in particular – in higher educational institutions; deduction and induction, analysis and synthesis – to identify systemic problems of Ukrainian universities the needs satisfaction of educational services users; the synthesis of progressive ideas on designing ways to enhance the teacher’s positive image in the context of the growth of the status of higher education institutions. Also, special-disciplinary methods of scientific research are used: comparison, systematization and grouping – to generalize the model of development of theoretical aspects of creating of a positive image of the teacher in the context of the formation of the image of the university; analytical – in the analysis of the interdependence of the teacher's image and his professional competence, practical skills and ability to associate theory with practice, etc. The result of the study is a theoretical understanding of the teacher’s image in the context of the formation of the competitiveness of a higher educational institution. The result of the analysis is the constant, systematic improvement of their own professional competencies. And only under this condition, the teacher will be able to rely on the authority and respect among students and colleagues. It is noted that the current state of higher education dictates the necessity of finding new ways of solving problems of increasing the efficiency of not only training, preparation of a specialist in the labor market, but also the efficiency of the activity of a higher educational establishment in conditions of autonomy. Conclusion. The positive image of the teacher, and in general the educational institution, will increase the authority of the professions and specialties of higher education. And philosophy itself should assume responsibility for the formation of the future teacher, since since ancient times, philosophy has been, is and will be the reason for the comprehension of wisdom. The image of a modern teacher largely depends on his professional competence in practical skills and the ability to instruct students to study the theory in close relationship with practice. After all, knowledge becomes effective only in the applied aspect, in particular, when applying the principle of “theory-practice-theory". (shrink)
