The relation between quantum measurement and thermodynamically irreversible processes is investigated. The reduction of the state vector is fundamentally asymmetric in time and shows an observer-relatedness which may explain the double interpretation of the state vector as a representation of physical states as well as ofinformation about physical states. The concept of relevance being used in all statistical theories of irreversible thermodynamics is demonstrated to be based on the same observer-relatedness. Quantum theories of irreversible processes implicitly use an objectivized process (...) of state vector reduction. The conditions for the reduction are discussed, and it is concluded that the final (subjective) observer system may be carried by a space point. (shrink)

Originally published in 1936, this book presents the ancient Greek text of the paraphrases and quotations of Zeno's philosophical arguments, together with a facing-page English translation and editorial commentary. Detailed notes are incorporated throughout and a bibliography is also included. This book will be of value to anyone with an interest in Zeno and ancient philosophy.

The interpretations of measurements in Bohm's and Everett's quantum theories are compared. Since both theories are based on the assumption of a universally valid Schrödinger equation, they face the common problem of how to explain that arrow of time, which in conventional quantum theory is represented by the collapse of the wave function. Its solution requires, in a statistical sense, a very improbable initial condition for thetotal wave function of the universe. The historical importance of Bohm's quantum theory is pointed (...) out.

It is argued by means of analogy with certain irreversible processes that a symmetry-violating vacuum need not necessarily be explained by a special cosmic initial condition.

Dans ce volume considérable, on été réunies les contributions d'un Congrès international tenu à Louvain en 1998 pour marquer l'achèvement de la première édition de la Théologie Platonicienne de Proclus. Ces contributions, toutes rigoureusement centrées sur la Théol. Plat. concernent (1) les principes et les sources de la Théol. plat. (2) Les méthodes théologiques de Proclus (3) La postérité de la Théol. plat. dans le monde grec, païen comme chrétien, et dans le monde islamique. Des indices très détaillés permettent de (...) retrouver tous les passages cités et commentés dans ce volume. (shrink)

It is demonstrated that neither the arguments leading to inconsistencies in the description of quantum-mechanical measurement nor those “explaining” the process of measurement by means of thermodynamical statistics are valid. Instead, it is argued that the probability interpretation is compatible with an objective interpretation of the wave function.

The program of a physical concept of information is outlined in the framework of quantum theory. A proposal is made for how to avoid the intuitive introduction of observables. The conventional and the Everett interpretations in principle may lead to different dynamical consequences. An ensemble description occurs without the introduction of an abstract concept of information.

The object of this paper is to show the predominance of the influence of geometrical ideas in Aristotle's account of first principles in the Posterior Analytics— to show that his analysis of first principles is in its essentials an analysis of the first principles of geometry as he conceived them. My proof of this falls into two parts. I. A consideration of the parallel between Aristotle's and Euclid's account of first principles. II. A comparison between the general movement of thought (...) in the Aristotelian παγωγ and πδειξις and in the δινοια and νησις of the Platonic dialectic. (shrink)

In a recent paper I attempted to show that Plutarch founded his Timoleon upon a Hellenistic biography and made direct use of Timaeus only for the major episodes, where the material contained in this biography was insufficient. The Pelopidas is similar in colouring to the Timoleon, both belonging to what might be described as the ‘chivalrous hero’ class of Plutarch's Lives. Yet this similarity does not originate from the use of similar authorities; for in writing the Pelopidas he was compelled (...) by the nature of the sources available to him to adopt an entirely different process of composition. The bulk of the Life is, as I hope to show, directly derived from the work of a fourth-century historian, and a considerable amount of supplementary material is added from miscellaneous sources.

If I were asked to put forward an ethical principle which I considered to be especially certain, it would be that no one can be responsible, in the properly ethical sense, for the conduct of another. Responsibility belongs essentially to the individual. The implications of this principle are much more far-reaching than is evident at first, and reflection upon them may lead many to withdraw the assent which they might otherwise be very ready to accord to this view of responsibility. (...) But if the difficulties do appear to be insurmountable, and that, very certainly, does not seem to me to be the case, then the proper procedure will be, not to revert to the barbarous notion of collective or group responsibility, but to give up altogether the view that we are accountable in any distinctively moral sense.

The excursus of Thucydides on the last years of Pausanias and Themistocles is remarkable for its simple, rapid-flowing style, its storytelling tone, its wealth of personal ancedote, its marked deviation from his normally strict criteria of relevance. These characteristics, which give the excursus a Herodotean flavour, have often been noted by modern scholars, but until recently acceptance of its general credibility has been widespread, and indeed, with one important exception, which seems to have created very little impression almost unchallenged.

The problem which I propose to consider is not whether the distinctions past, present, future, characterize the form of time in such a way that whatever may be true concerning the reality of one of these characteristics must be equally true of the others, but the more particular question of the kind of existence which belongs to the content of the past, or its constituents as events.

The development of transplantation technology increasingly places before society a multitude of diverse, complex ethical and legal problems. The subject is the more complex because of the various divergent interests involved. There are the interests of the donor of organs, who has a right to protection of his legal position, and those of the patient in need of an often lifesaving organ. There are also the interests of the donor’s relatives, after his death, and those of the transplantation surgeons. The (...) international dimension of transplantation technology makes the picture even more complicated. Though this article is devoted to the European situation, the problems are similar all over the world. (shrink)

First published in 1962, Freedom and History expresses a deep concern about freedom and the way it is imperilled by misunderstandings. Professor Lewis examines works of T.H. Green and compares Green with Locke and Rousseau.

The following remarks on the aviary simile have been prompted by Professor Hackforth's article in C.Q. January 1938, pp. 27 ff., in which he in turn comments on certain points in Professor Cornford's treatment in his Plato's Theory of Knowledge. Commenting on 199c–d C. suggests that P.'s criticism in that passage might be met by the inclusion in the aviary of ‘complex objects such as the “sum of 7 and 5”.… It is this object that I identify with 11 when (...) I make my false judgement.… False judgement can be explained as the wrong putting together of two pieces of knowledge’—i.e. 11 and ‘the sum of 7 and 5’. C. further suggests that P. has overlooked this possibility because he persists in speaking as if we judged not ‘that the sum of 7 and 5 is 11’ but that ‘12 is 11 ’. H. replies that this criticism of C.'s is not valid because P. understands the knowledge of 11 and 12 to include a knowledge of the various sums that make up these numbers. There could, therefore, be no ‘question of “putting together” such a piece of knowledge as 7 + 5 = 12 with a different piece of knowledge, viz. the knowledge of 12. They are not different pieces; they are the same piece.’. (shrink)
