We show how mereotopological notions can be expressed by extending intuitionistic propositional logic with propositional quantification and a strong modal operator. We first prove completeness for the logics wrt Kripke models; then we trace the correspondence between Kripke models and topological spaces that have been enhanced with an explicit notion of expressible region. We show how some qualitative spatial notions can be expressed in topological terms. We use the semantical and topological results in order to show how in some extensions (...) of the logics it is possible to express connectedness, non-emptiness and a set of jointly exhaustive, pairwise disjoint, binary relations that play a significant role in qualitative spatial reasoning.

Foreword to new edition / George Bennett -- Original foreword / Elizabeth Bennett -- The diaries July 23, 1949-November 7,1949 -- Additional entries November 8-22, 1949.

Talks collected from lectures given by Bennett with Gurdjieff's approval, to help people understand All and Everything: Beelzebub's Tales to His Grandson. Bennett regarded Gurdjieff's All and Everything as a work of superhuman genius.

These diary entries from John and Elizabeth Bennett cover the few months before Gurdjieff's death in Paris on October29, 1949. Twice daily the group would go through a series of rituals, the most significant of which was known as "the toast of the idiots". This "science of idiotism" portrayed the human situation and the hazards of attaining liberation.

Nelson Goodman has provided one of the most exciting advances in semiotic aesthetics in years in his recent book, Languages of Art. Among other theses that Goodman defends is the claim that pictures are elements of symbol systems to be understood in the way that languages are understood: that depiction and description are species of a common genus which is to be understood in terms of denotation. One of the consequences Goodman draws from his theory is that depiction is conventional: (...) the fact that a certain picture depicts a man is as much a matter of convention as the fact that a certain phrase describes him. This claim is interesting and exciting, but is it correct? Unfortunately, I do not think we are yet in a position to answer this last question, although I shall try to get nearer to an answer in this paper. (shrink)

The underdetermination thesis poses a threat to rational choice of scientific theories. We discuss two arguments for the thesis. One draws its strength from deductivism together with the existence thesis, and the other is defended on the basis of the failure of a reliable inductive method. We adopt a partially subjective/objective pragmatic Bayesian epistemology of science framework, and reject both arguments for the thesis. Thus, in science we are able to reinstate rational choice called into question by the underdetermination thesis.

In lieu of an abstract, here is a brief excerpt of the content:The Power of PersuasionG. Bennett HumphreyA long white coat, the title of doctor, a practiced professional persona and an appointment to the staff of a prestigious university medical center allows the physician to be a persuader of clinical decisions affecting patient management. When this power of persuasion is used to encourage patient compliance with a therapeutic regimen that might be curative for a fatal disease, there is justification (...) for trying to influence the patient to make choices resulting in a positive outcome. But when a physician is asking permission to enter the patient into a research protocol where the primary goal of the study is the hope of advancing knowledge, then much thought needs to be given to the potential abuse of this power of persuasion.In the 1960s, I found myself having to think about recruiting children into research protocols. I had just finished two years of residency in internal medicine and wanted to pursue a career in academic medicine. My primary interest was in laboratory research. To strengthen my training in research, I had competed for a position as clinical fellow in a western university. The fellowship program was designed to expose young physicians to both clinical and laboratory research. The first year was spent on one of the clinical research wards and the second year in a research laboratory. The program was open to residents from surgery, medicine and pediatrics but because there was a shortage of pediatricians in the program, I was required to work on the children’s leukemia ward for one year.The learning curve was steep during the first few months. Naturally, the faculty in pediatrics and the medical literature gave me a technical education in the use of protocols for therapeutic treatment of leukemia. For example, the first protocol used was designated as Phase III, and the goal was to try to cure the patient. A remission could be achieved in over 90 percent of children but the disease recurred. The median duration of these remissions in the mid–1960s was one year. A relapse was followed by progressive disease and death in a matter of weeks, but a new drug of unknown efficacy could be administered. This was a Phase II protocol, and while there was a chance of prolonging life for a month or so, the primary goal was the identification of drugs anti–leukemic activity.The pediatric leukemia ward experience for me as a fellow was unusual. There was more to learn than the treatment of leukemia. To my surprise, the children and their mothers gave me insight into the care of pediatric patients. Each month, the patients were admitted for five days of intravenous chemotherapy. The first day was traumatic with venipunctures, bone marrow aspirations and the establishment of an IV for the daily infusion of drugs. The remaining four days were for social rounds: listening to the children who liked to talk; talking with the ones who liked to listen; putting puzzles together with some toddlers; responding to a request to listen to the heart of a much loved teddy bear; exchanging jokes and riddles; stories about school, the family dog, or a favorite friend; enjoying the banter of the adolescents; and not invading the privacy of a few who didn’t like me, the ward or the therapy. These children were sharing their childhood with me and it took couple of months for me to recognize I was bonding with these little patients. I observed and listened to the mothers caring for their children and stood in awe of the resources that they brought to bear on having children with a fatal disease. A feeling of mutual respect and trust developed between these mothers and me. For an internist, these experiences were profound and very different from my experience treating adults.A professor, an internationally known researcher in the field of leukemia, was in charge of the ward. Formal rounds were conducted on Tuesday mornings when the result of the bone marrow aspirates and the toxicity of the chemotherapy were reviewed. The day–to–day responsibility for [End Page 101] treatment and informing the mothers on the remission status on Mondays was my responsibility... (shrink)

The present paper examines the arguments and data presented by Nisbett and Wilson relevant to their thesis that subjects do not have access to their own cognitive processes. It is concluded that their review of previous research is selective and incomplete and that the data they present in behalf of their thesis does not withstand a demand characteristics analysis. Furthermore, their use of observer-subject similarity as evidence of subjects' inability to access cognitive processes makes tests of their hypothesis confounded and, (...) at the same time, reveals limitations in the application of the pre-inquiry quasi-control to research on social behavior. Problems with postexperiment questionnaires, such as the demand characteristics of the inquiry procedure are also considered. Although there are difficulties in assessing subjects' cognitive processes, many of these may be overcome through the application of novel techniques and research conducted on more traditional methods. In contrast to the view that subjects have limited access to cognitive processes and that their verbal reports are not valid, it is concluded that subjects' verbalizations are a rich source of psychological data which must be pursued if we are to tap their cognitive processes and are to gain an adequate understanding of human behavior.

Copenhagen interpretation of quantum mechanics deals with these problems is reviewed. A new interpretation of the formalism of quantum mechanics, the transactional interpretation, is presented. The basic element of this interpretation is the transaction describing a quantum event as an exchange of advanced and retarded waves, as implied by the work of Wheeler and Feynman, Dirac, and others. The transactional interpretation is explicitly nonlocal and thereby consistent with recent tests of the Bell inequality, yet is relativistically invariant and fully causal. (...) A detailed comparison of the transactional and Copenhagen interpretations is made in the context of well-known quantum-mechanical Gedankenexperimenre and "paradoxes." The transactional interpretation permits quantum-mechanical wave functions to be interpreted as real waves physically present in space rather than as "mathematical representations of knowledge" as in the Copenhagen interpretation. The transactional interpretation is shown to provide insight into the complex character of the quantum-mechanical state vector and the mechanism associated with its "collapse." It also leads in a natural way to justification of the Heisenberg uncertainty principle and the Born probability law (P = ii iij*), basic elements of the Copenhagen interpretation. (shrink)

This book shines bright light into the dim recesses of quantum theory, where the mysteries of entanglement, nonlocality, and wave collapse have motivated some to conjure up multiple universes, and others to adopt a "shut up and calculate" mentality. After an extensive and accessible introduction to quantum mechanics and its history, the author turns attention to his transactional model. Using a quantum handshake between normal and time-reversed waves, this model provides a clear visual picture explaining the baffling experimental results that (...) flow daily from the quantum physics laboratories of the world. To demonstrate its powerful simplicity, the transactional model is applied to a collection of counter-intuitive experiments and conceptual problems. (shrink)

The works of Paul K. Feyerabend, Norwood Russell Hanson and Thomas S. Kuhn have come to occupy a central place in the annals of contemporary philosophy of science. Some of their contemporaries,, tend to regard them as the vanguard of a new “revolutionary” intellectual movement. Reacting against the views of their positivist predecessors, they embrace and propagate the idea that “pervasive presuppositions” are fundamental to scientific investigations. Thus, Feyerabend thinks that, “... scientific theories are ways of looking at the world; (...) and their adoption affects our general beliefs and expectations, and thereby also our experiences and our conception of reality”. This is in stark contrast to the positivist view that the aim of science is the systematization of experience that exists independently of any scientific theories. This new view of scientific theories also involves a “radical” conception of the nature of theoretical change. Rejecting the positivist notion of any constant element through such change, Kuhn regards a basic theoretical change as a conceptual revolution and “wants to say that after a revolution scientists are responding to a different world”. Hanson uses the phrase ‘theory-loaded’ to give expression to a view of the semantic content of observation statements that follows from this general position. (shrink)

The appearance of Priestley's electrical work as a brief and irrelevant prelude to his more substantial chemical enquiries may explain why it has been strangely overlooked by historians of science. It was only fairly recently that Sir Philip Hartog sought to rectify this situation with the affirmation that ‘Priestley's electrical work offers the key to Priestley's scientific mind’. Attacking traditional chemical historiography for tracing Priestley's opposition to Lavoisier's theory to a deficiency in his scientific sensibilities, Hartog insisted that Priestley's natural (...) philosophy can properly be understood only in relation to his ‘profound convictions on scientific method’ as fully expressed in the History of electricity. Only thus would Priestley's scientific thought be related correctly to his ‘work as a whole’. (shrink)
