With the publication of these two volumes the ground has now been prepared for a long awaited event, the critical edition of the works of Henry of Ghent. Henry was one of the outstanding philosophizing-theologians at the University of Paris in the second half of the thirteenth century and, during the period between the death of Thomas Aquinas in 1274 and the ascendancy of John Duns Scotus near the beginning of the fourteenth century, no other Master surpassed him in terms (...) of influence or importance. During his tenure there as Master in the theology faculty, Henry conducted fifteen Quodlibetal disputes. His written versions of these, along with his Summa of ordinary Disputed Questions, constitute his most important surviving works. And of these, his Quodlibets rank first. Henry's philosophical and theological views were highly original and drew considerable reaction from other leading Masters of the time, especially from Giles of Rome, Godfrey of Fontaines, and somewhat later, from Duns Scotus. While his personal thought cannot be reduced to that of any earlier thinker or tradition, his views were heavily influenced by Augustine, by Avicenna, and by various other Neoplatonic currents. At the same time, while he was quite familiar with the texts and thought of Aristotle, he reacted strongly against the more radical form of Aristotelianism developed by Siger of Brabant, Boethius of Dacia, and other Masters in the Arts Faculty at Paris in the 1260s and 1270s. Aquinas's incorporation of many Aristotelian positions into his own thought was also suspect in Henry's eyes. Given this background, Henry himself may be regarded as an outstanding representative of the Neo-Augustinian philosophical current which surfaced at Paris around 1270, which triumphed with the condemnation of 219 propositions by Stephen Tempier, Bishop of Paris, in 1277, and which would continue to be a dominant philosophical force until the end of the century. The need for a critical edition of his Quodlibets and his Summa has long been recognized, since the only printed versions date from the sixteenth and seventeenth centuries. In these first two volumes of Henry's Opera omnia Macken has prepared the way for the critical edition of Henry's works and especially of his Quodlibets. Here one finds a valuable catalog, based on first-hand inspection, of the widely scattered manuscripts of Henry's works. The catalog also contains expert codicological descriptions of the contents of these manuscripts, including works whose authenticity remains doubtful. Manuscripts are also considered which contain works that treat ex professo of Henry's doctrine. This is followed by an appendix which surveys ancient references to other manuscripts allegedly containing Henry's works, which manuscripts have not yet been found. Then there is a Répertoire, not of manuscripts but of Henry's works themselves, including certainly authentic works, works of doubtful authenticity, and finally, in another short appendix, works which have been falsely ascribed to him. A third part of this survey of Henry's works is devoted to manuscripts of other writers who discuss Henry's doctrine ex professo. The two volumes conclude with all the necessary indices. One must congratulate Macken for the care, the industry, and the meticulous scholarship with which he has prepared these two volumes. Not only are they of great value to anyone interested in the manuscript tradition of Henry's works and doctrine; they also include helpful descriptions of the writings of many other medieval authors which are contained in many of these same manuscripts. They will undoubtedly be carefully combed for decades to come by other scholars interested in these same authors and manuscripts. These volumes will be indispensable for libraries of institutions making any serious claim to expertise in the history of medieval philosophical and theological thought. One can only wish Macken and his international team of collaborators every success in their next immediate task, the actual edition of Henry's most important works, his fifteen Quodlibetal Questions.--J.F.W.

The criminal law presently distinguishes between actions and omissions, and only rarely proscribes failures to avert consequences that it would be an offense to bring about. Why? In recent years it has been persuasively argued by both Glover and Bennett that, celeris paribus, omissions to prevent a harm are just as culpable as are actions which bring that harm about. On the other hand, and acknowledging that hitherto “lawyers have not been very successful in finding a rationale for it,” Tony (...) Honoré has sought to defend the law's differential treatment. He proposes a “distinct-duties theory” that in addition to the general duties we owe to everyone, we also owe distinct duties to a more limited collection of people and associations, specified by features of our relationship with them. Where a distinct duty holds, breach by omission may well be no better than breach by positive action. But absent a distinct duty, omissions, per Honoré, are less culpable. They are mere failures to intervene and improve or rectify things, whereas actions are positive interventions which make things worse. And, thus, the law has good reason to differentiate between them. (shrink)

The paper considers the intellectual computer mathematics system InparSolver, which is designed to automatically explore and solve basic classes of computational mathematics problems on multi-core computers with graphics accelerators. The problems of results reliability of solving problems with approximate input data are outlined. The features of the use of existing computer mathematics systems are analyzed, their weaknesses are found. The functionality of InparSolver, some innovative approaches to the implementation of effective solutions to problems in a hybrid architecture are described. Examples (...) of applied usage of InparSolver for processes mathematical modeling in various subject areas are given. Nowadays, new more complex objects and phenomena in many subject areas are constantly emerging, which are subject to mathematical research on a computer. This encourages the development of new numerical methods and technologies of mathematical modeling, as well as the creation of more powerful computers for their implementation. With the advent and constant development of supercomputers of various architectures, the problems of their effective use, expansion of tasks range should be solved, ensuring the reliability of computer results and increasing the level of intellectual information support for users ‒ specialists in various fields. Today, the issues of solving these problems are given special attention by many specialists in the fields of information technology and parallel programming. The world's leadingscientists in the field of computer technology see the solution to the problems of efficient usage of modern supercomputers in algorithmic software creation that easily adapts to different computer architectures with different types of memory and coprocessors, supports efficient parallelism on millions of cores etc. In addition, improving the efficiency of high-performance computing on modern supercomputers is provided by their intellectualization, transferring to the computer to perform a significant part of the functions. The industry of development and usage of intelligent computer technologies is one of the main directions of science and technology development in modern society. (shrink)

Dio-Xiphilinus, Herodian, and the Historia Augusta give three apparently contradictory accounts of the circumstances in which Commodus' all-powerful praetorian prefect, Sex. Tigidius Perennis, was overthrown in A.D. 185. My purpose here is not to try to decide between them, but primarily to correct what I think a patent misinterpretation, now current, of a crucial statement in that given by Xiphilinus in his epitome of Dio.

Lenin's work "On the Significance of Militant Materialism," written in the spring of 1922, is justly regarded as the philosophical testament of our leader. In it, the tasks of the day were merged with the tasks of the entire epoch on the basis of a profound analysis of reality.

All projects take place within a context of uncertainty. That is especially noticeable in complex hydroelectric power generation projects, which are affected by factors such as the large number of multidisciplinary tasks to be performed in parallel, long execution times, or the risks inherent in various fields like geology, hydrology, and structural, electrical, and mechanical engineering, among others. Such factors often lead to cost overruns and delays in projects of this type. This paper analyzes the efficiency of the Earned Value (...) Management technique and its Earned Schedule extension, as means of forecasting costs and deadlines when applied to complex hydroelectric power production projects. It is worth noting that this analysis was based on simulation models applied to real-life projects. The results showed that cost forecasting becomes very accurate over time, whereas duration forecasting is not reliably accurate. (shrink)

In this paper we investigate a number of analytical solutions to the polynomial class of nonlinear Klein-Gordon equations in multidimensional spacetime. This is done in the context of classical φ4 and φ6 field theory, the former with and without the inclusion of an external force field conjugate to φ. Both massive (m≠0) and massless (m=0) cases are considered, as well as tachyonic solutions allowed (v>c). We first present a complete set of translationally invariant solutions for the φ4 model and demonstrate (...) the role of external force fields in altering the form of these solutions. Next, spherically symmetric solutions are discussed in both φ4 and φ6 cases since they provide the most realistic models of elementary particles. (shrink)

Attitudes towards active voluntary euthanasia (AVE) and physician-assisted suicide (PAS) among 1,238 doctors on the medical register of New South Wales varied significantly with self-identified religious affiliation. More doctors without formal religious affiliation ('non-theists') were sympathetic to AVE, and acknowledged that they had practised AVE, than were doctors who gave any religious affiliation ('theists'). Of those identifying with a religion, those who reported a Protestant affiliation were intermediate in their attitudes and practices between the agnostic/atheist and the Catholic groups. Catholics (...) recorded attitudes most opposed to AVE, but even so, 18 per cent of Catholic medical respondents who had been so requested, recorded that they had taken active steps to bring about the death of patients.

Even though Plamondon's kinematic model fits the data well, we do not share the view that it explains movements other than ballistic ones. The model does not account for closed-loop control, which is the more common type of movement in everyday life, nor does it account for recent data indicating interference with ongoing processing.

When should we make use of the criminal law? Suppose that a responsible legislature seeks to enact a morally justifiable range of criminal prohibitions. What criteria should it apply when deciding whether to proscribe conduct? Crimes, Harms, and Wrongs is a philosophical analysis of the nature, significance, and ethical limits of criminalisation. The authors explore the scope and moral boundaries of harm-based prohibitions, proscriptions of offensive behaviour, and 'paternalistic' prohibitions aimed at preventing self-harm. Their aim is to develop guiding principles (...) for these various grounds of state prohibition, including an analysis of the constraints and mediating factors that weigh for and against criminalisation. Both authors have written extensively in the field. In Crimes, Harms, and Wrongs they have reworked a number of well-known essays and added several important new essays to produce an integrated, accessible, philosophically-sophisticated account that will be of great interest to legal academics, philosophers, and advanced students alike"--Provided by publisher.

This paper explores the Offence Principle. It discusses whether two constraints, additional to the criteria stated in conventional analysis, ought to be met before the Offense Principle can be satisfied: (i) that offensive conduct must be a wrong, and (ii) that the conduct must also lead to harm. The nature of the Harm Principle, and its relationship to the Offense Principle, are also considered. The paper suggests that, even if all cases in which offense should be criminalized also involve harm, (...) nonetheless there may be good reasons to retain a separate Offense Principle. (shrink)
