ABSTRACT Real-time graphical interval logic is a modal logic for reasoning about time in which the basic modality is the interval. The logic differs from other logics in that it has a natural intuitive graphical representation that resembles the timing diagrams drawn by system designers. We have developed an automted deduction system for the logic, which includes a theorem prover and a user interface. The theorem prover checks the validity of proofs in the logic and produces counterexamples to invalid proofs. (...) The user interface includes a graphical editor that enables the user to create graphical formulas on a workstation display, and a database and proof manager that tracks proof dependencies and allows graphical formulas to be stored and retrieved. In this paper we describe the logic, the automated deduction system, and an application to robotics. (shrink)

Quale atteggiamento deve assumere il cristiano in filosofia? Se la condizione di cristiano è tale da influire sulle modalità della riflessione filosofica, che cosa ne consegue per il rapporto tra la fede e la ricerca della verità? I due autori, entrambi cristiani, hanno approcci diversi al riguardo, sotto il profilo dell’ispirazione intellettuale, degli approfondimenti tematici e dello stile espositivo, ma è comune a entrambi il desiderio di riflettere sull’amore e l’obbedienza come fonti della filosofia del credente. -/- Questo piccolo libro (...) realizza un’eco italiana del dibattito intorno a «una filosofia conforme a Cristo», molto vivo soprattutto nei paesi anglosassoni, qui articolato con un costante riferimento al pensiero di san Tommaso d’Aquino, così centrale nella tradizione religiosa e culturale del nostro Paese.

Книга «Производительные силы и исторический процесс» из числа тех редких, но очень нужных исследований, которые пытаются выявить роль сквозных факторов исторического процесса и причины изменения этой роли. Книга посвящена исследованию развития от первобытности до современности мировых производительных сил как важнейшей составной части исторического процесса. Особое внимание уделено рассмотрению производственных революций (аграрной, промышленной и научно-технической). Прослежена также взаимосвязь производственного и других аспектов исторического процесса: политического, социального, этнического и духовного. Книга будет полезна не только специалистам в области социальной философии, исторической социологии и (...) теоретической истории, но также всем интересующимся проблемами теории исторического процесса или развития мирового хозяйства. Она способна помочь преподавателям, аспирантам и студентам и может быть использована в качестве учебного пособия для отдельных спецкурсов. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 133 of its time and nothing beyond that, while in classical historicism every philosophy was a step in the progressive manifestation of truth not only a historical phenomenon. As a result it iustified not only a historicist treatment but also a speculative discussion of its truth-content. These genuine philosophies may be nonetheless rooted in their own time as we all are, but in philosophy as in life (...) everybody is confronted with a decision whether he wants to be merely a part of history or whether he wants to have history, i.e. also to have the link with true being. Pareyson's theory of interpretation is specially tailored to the reconciliation of the multiplicity of philosophies and of the unity of philosophical thought, aiming at ontological truth. All philosophies are personal interpretations of the world, yet they have an indestructible content of ontological truth that surpasses their own time. We shall not err if we compare Pareyson's interpretation with what Joseph Scbelling called "intelektuelle Anschauung," i.e. the intuitive penetration of what he called the Absolute. Pareyson protests also against the claims of the humanistic sciences, such as sociology, anthropology and cultural history, to replace philosophy. All these sciences canhot replace the function of philosophy as described above. Pareyson uses a very illuminating metaphor: interpreting truth is like interpreting a musical score. While any such interpretation may be legitimate, all may be different and all are personal. But the musical score is always the same. The musical score is compared here with the ontological truth of philosophical thought, while the various readings of the score are the various historical philosophies. By so doing Pareyson avoids the error of Heidegger who rejected all historical philosophies from Parmenides to Nietzsche. MAx RINSER New York Ctty Moser, Shia. Absolutism and Relativism in Ethics. (Springfield, Ill., Thomas, 1968) In the last twenty years our ethics textbooks have been modeled upon the topics of normative and critical ethics. Eventually one finds appended to these main subjects discussions on moral determinism and relativism. While the former problem continues to foster much rigorous scholarship, both substantive and analytic, the germane issue of relativism has been seldom set forth today in a clear and convincing fashion. The fleeting recognition the problem receives in our textbooks renders homage to the curiosity of the student rather than encourages research in the origin, variability and validity of moral ideas,x The several articles 2 of any philosophical impact written after A. Edel essayed refutation of Westermarck's relativity thesis by appealing to invariant factors in the social sciences, fare no better. Although it is true that this recent literature has opened An exception is Maria Ossowska's, Social Determinants of Moral Ideas (Philadelphia, 1970); this book belongs to the tradition of A. Edel and is an excellent example of fruitful research in the sociology of morals. 2 C. Wellman, "The Ethical Implications of Cultural Relativity," Journal of Philosophy 60 (1963): 169-184; J.

It seems to me that if one construes relativism in terms of one component of J. Ladd's thesis,3 i.e., moral ideas are causally dependent on socio-cultural determinants of some kind, there is substantially no difference between the alleged moral implications of relativism and those of determinism. Indeed relativism so interpreted becomes entangled in one of the problems peculiar to determinism, which is the difficulty of ascribing responsibility to societies and individuals. Thus the determinist's avowed impotence to blame and praise coincides with the relafivist's virtue of tolerance.4 By the same token one could exploit the determinist's model and speak of hard relativism, soft relativism and...

This study is an attempt to construct a quantitative link for international regimes with global leadership. The country's willingness to lead in solving global issues as the first mover in the formation of an international regime is measured and characterized by analyzing their ratification behavior in multilateral conventions deposited to the United Nations which shape of the global community. For this purpose, a set of quantitative indicators, the Index of Global Leadership Willingness and the Global Support Index, was defined and (...) calculated for each country based on its actual ratification year data for 120 multilateral conventions covering global issues such as peace and security, environment, commerce, communication, intellectual property protection, human rights, and labor. By proposing a framework of global leadership analysis, the study seeks to provide an empirical testing of the transformation of global governance towards cooperation without hegemony paradigm. The paper analyses changes in the leadership willingness indices of selected country groups, such as the G3, G7/8, and G20, over the century and finds that the will to drive the international agenda of these groups of leaders is in decline. Moreover, our study provides evidence to argue that our current world is actually without consistent global leadership across domains of the world affairs. Although several countries still show visible leadership in specific policy domains, such as environment and intellectual property, neither the G7/8 nor the G20 was playing a comparable role to those performed by the G3 a hundred years ago.

Prominent thinkers such as Jurgen Habermas and Michael Sandel are warning that biomedical enhancements will undermine fundamental political values. Yet whether biomedical enhancements will undermine such values depends on how biomedical enhancements will function, how they will be administered and to whom. Since only few enhancements are obtainable, it is difficult to tell whether these predictions are sound. Nevertheless, such warnings are extremely valuable. As a society we must, at the very least, be aware of developments that could have harmful (...) consequences. Indeed, if important values were to be jeopardized, we should take appropriate measures to protect them. This paper focuses on four central values: solidarity, personal responsibility, equality and autonomy. It delineates the conditions under which biomedical enhancements would undermine these values. It also details the circumstances under which these values would be unaffected by enhancements as well as those under which they would be promoted. Specifying these conditions is valuable; it would enable society to prepare appropriate ethical guidelines and policy responses in advance. (shrink)

Abstract. We argue that all human beings have a special type of dignity which is the basis for (1) the obligation all of us have not to kill them, (2) the obligation to take their well-being into account when we act, and (3) even the obligation to treat them as we would have them treat us, and indeed, that all human beings are equal in fundamental dignity. We give reasons to oppose the position that only some human beings, because of (...) their possession of certain characteristics in addition to their humanity (for example, an immediately exercisable capacity for self-consciousness, or for rational deliberation), have full moral worth. What distinguishes human beings from other animals, what makes human beings persons rather than things, is their rational nature, and human beings are rational creatures by virtue of possessing natural capacities for conceptual thought, deliberation, and free choice, that is, the natural capacity to shape their own lives.

The projection postulate, which prescribes “collapse of the state vector” upon measurement, is not an essential part of quantum mechanics. Rather it is only an optional discarding of certain branches of the state vector that are expected to be irrelevant for the purpose at hand. However, its use is hazardous, and there are examples of repeated measurements for which the conventional application of the projection postulate leads to incorrect results.

Argument-places play an important role in our dealing with relations. However, that does not mean that argument-places should be taken as primitive entities. It is possible to give an account of ‘real’ relations in which argument-places play no role. But if argument-places are not basic, then what can we say about their identity? Can they, for example, be reconstructed in set theory with appropriate urelements? In this article, we show that for some relations, argument-places cannot be modeled in aneutralway in (...) V[A], the cumulative hierarchy with basic ingredients of the relation as urelements. We argue that a natural way to conceive of argument-places is to identify them with abstract, structureless points of a derivative structure exemplified by positional frames. In case the relation has symmetry, these points may be indiscernible. (shrink)

The attempt to derive (rather than assume) the statistical postulate of quantum theory from the many-universes interpretation of Everett and De Witt is analyzed The many-universes interpretation is found to be neither necessary nor sufficient for the task.

A version of scattering theory that was developed many years ago to treat nuclear scattering processes, has provided a powerful tool to study universality in scattering processes involving open quantum systems with underlying classically chaotic dynamics. Recently, it has been used to make random matrix theory predictions concerning the statistical properties of scattering resonances in mesoscopic electron waveguides and electromagnetic waveguides. We provide a simple derivation of this scattering theory and we compare its predictions to those obtained from an exactly (...) solvable scattering model; and we use it to study the scattering of a particle wave from a random potential. This method may prove useful in distinguishing the effects of chaos from the effects of disorder in real scattering processes. (shrink)

The complex mechanisms by which nonlinear classical conservative systems undergo a transition from quasiperiodic to chaotic behavior are now fairly well understood. This transition is associated with a breakdown of quasi-constants of motion (KAM surfaces). There is growing evidence that similar mechanisms may govern the behavior of quantum systems. While K-type mixing behavior has not yet been found, there does appear to be a transition associated with the destruction of a quantum quasi-constant of motion (quantum KAM states) which changes qualitatively (...) the spectrum of quantum systems.

Cultural narratives shape how we think about the world, including how we decide when the end of life begins. Hospice care has become an integral part of the end‐of‐life care in the United States, but as it has grown, its policies and practices have also imposed cultural narratives, like those associated with the “six‐month rule” that the majority of the end of life takes place in the final six months of life. This idea is embedded in policies for a range (...) of care practices and reimbursement processes, even though six months is not always a meaningful marker. In the case of people living with advanced dementia, six months is both too early in the trajectory to facilitate conversations and too late in the trajectory to ensure decision‐making capacity. This essay encourages scholars and policy‐makers to consider how cultural narratives may limit what they think is possible in care for people living with dementia. (shrink)
