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.

Description: Ancient Indian logic by itself is a very vast subject. The ancient Sanskrit term nyaya which was first used in a different or in a much more general sense, was later specifically applied to the Nyaya school. The physics and physiology and psychology of the Nyaya doctrine are not specifically its own, being from the first indistinguishable from those of its sister Sastra, the Vaisesika. What characterizes it specifically is the development of the nyaya or five-membered method of demonstration (...) and its insistence on the four sources of knowledge, corresponding to the first four members of its demonstrative formula, or 'Syllogism.' The importance of Nyaya is in its doctrine of the pramanas, or sources of proof, and in its formulation of the nyaya, or method of demonstration. Indian Logic in its Early Schools by H.N. Randle is an interpretation of Indian logical theory in its historical development based on the study of original texts wherever reference to Nyaya as a method of logic has been made, and thus, covers a very wide field of Indian philosophy. An indispensable work for students of Indian philosophy, it is especially important for those who are interested in Nyayadarsana in its relation to the early logic of other schools. (shrink)

In the Platonic work Alcibiades I, a divinely guided Socrates adopts the guise of a lover in order to divert Alcibiades from an unthinking political career. The contributors to this carefully focussed volume cover aspects of the background to the work; its arguments and the philosophical issues it raises; its relationship to other Platonic texts, and its subsequent history up to the time of the Neoplatonists. Despite its ancient prominence, the authorship of Alcibiades I is still unsettled; the essays and (...) two appendices, one historical and one stylometric, come together to suggest answers to this tantalising question.

In this paper, the model predictions are compared with experimental results obtained under discontinuous presentation of an ambiguous stimulus. In addition to earlier results for long inter-stimulus intervals, we show that the reversal dynamics according to the Necker-Zeno model is also in agreement with new results for short inter-stimulus intervals. Moreover, we refine the model in such a way that it accounts for the distribution of “dwell times”. Finally, we indicate applications concerning the modification of cognitive time scales under conditions of psychopathological impairments and meditationinduced modes of awareness. ∗Address correspondence to this author at the Theory Division of the Institute for Frontier Areas of Psychology, Wilhelmstr. 3a, D–79098 Freiburg, Germany; E-mail: haa@igpp.de.

The de minimis principle states that some risks are so trivial that they can be ignored or treated categorically differently from non-trivial risks. Lundgren and Stefánsson criticize the de minimis principle, arguing that it either has to be applied locally or globally and that problems arise whichever application is chosen. Aven and Seif respond to Lundgren and Stefánsson’s argument and defend the de minimis principle as a “meaningful and useful perspective for handling risk in practice.” The response highlights some aspects (...) of the argument in Lundgren and Stefánsson that needs clarification, which is what we do in this note.
