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.

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...

The current article aims to provide an up-to-date synopsis of available techniques to study affect dynamics using intensive longitudinal data. We do so by introducing the following eight dichotomies that help elucidate what kind of data one has, what process aspects are of interest, and what research questions are being considered: single- versus multiple-person data; univariate versus multivariate models; stationary versus nonstationary models; linear versus nonlinear models; discrete time versus continuous time models; discrete versus continuous variables; time versus frequency domain; (...) and modeling the process versus computing descriptives. In addition, we discuss what we believe to be the most urging future challenges regarding the modeling of affect dynamics. (shrink)

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)

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.

Abstract: While many commentators have remarked on Nietzsche’s admiration for the Greek historian Thucydides, most reduce the affinity between the two thinkers to their common commitments to “political realism” or “scientific naturalism.” At the same time, some of these same commentators have sought to minimize or dismiss Nietzsche’s enthusiasm for the Greek sophists. We do not deny the importance of realism or naturalism, but we suggest that, for Nietzsche, realism and naturalism are rooted in a rejection of moral absolutism and (...) its leading advocates, Socrates and Plato. Through careful exegesis of crucial sections from Daybreak, we show that, as early as 1880 (if not earlier), Nietzsche regarded the agonistic, anti-absolutist stance of the sophist Protagoras as an indispensable model both for Thucydides’s history and for his own philosophy.

In The Souls of Black Folk, W.E.B. Du Bois introduces double consciousness as a result of racial prejudice and oppression. Explained as a state of confliction felt by black Americans, Du Bois presents double consciousness as integral to understanding the black experience. Later philosophers question the importance of double consciousness to current race discussions, but this paper contends that double consciousness provides valuable insights into black and white relations. To do this, I will utilize the modern slang term, “Oreo,” to (...) highlight how a perceived incompatibility between blacks and whites could prevent America from achieving a greater unity. (shrink)

Following surveys identifying the need for ongoing learning in relation to law and ethics amongst health professionals, the Law and Ethics Education and Development initiative was launched. This was a programme of education designed for, and delivered to, health professionals working within the National Health Service , UK, with the added value of multiprofessional learning amongst colleagues from a single institution. The initiative was funded by the NHS Executive and provided for two lecturers to work for three years within the (...) northwest region. The lecturers, an academic lawyer based at the University of Liverpool, and an ethicist based at the University of Manchester worked in collaboration through the auspices of the Institute of Medicine Law and Bioethics.

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)

Medical educators invoke professionalism as a core competency in curricula. This paper criticizes classic definitions. It also identifies some negative traits of medicine as a profession. The call to professionalism is naive nostalgia. Straightforward didactics in professionalism cannot do the desired work in medical education. The most we can say is that students should adopt the good aspects of professionalism and the profession should stop being some of what it has been. This is a platitude. If the notion is to (...) be more than shallow, each student and practitioner will have to engage in much dialogue, reflection and refinement over many years. (shrink)
