Background: Recent research demonstrates that people sometimes make different medical decisions for others than they would make for themselves. This finding is particularly relevant to end-of-life decisions, which are often made by surrogates and require a trade-off between prolonging life and maintaining quality of life. We examine the impact of decision role, patient age, decision maker age and multiple individual differences on these treatment decisions. Methods: Participants read a scenario about a terminally ill cancer patient faced with a choice between (...) an aggressive chemotherapy regimen that will extend life by two years and palliative treatments to control discomfort for one remaining month. Participants were randomly assigned to one of three decision roles (patient, physician, or an abstract other) and the scenario randomly varied whether the patient was described as 25 or 65-years old. Results: When deciding for a 65-year old patient, approximately 60% of participants selected aggressive chemotherapy regardless of decision role. When deciding for a 25-year old patient, however, participants were more likely to select chemotherapy for a patient (physician role) or another person (abstract other) than for themselves (70%, 67%, and 59%, respectively). In addition, confidence that powerful others (eg, physicians) control one’s health, as well as respondents’ age and race, consistently predicted treatment choices. Conclusions: Patient age appears to influence medical decisions made for others but not those that we make for ourselves. These findings may help to explain the discord that often occurs when younger cancer patients refuse life-extending treatments. (shrink)

It is proposed in this paper to develop a method by which the most general problem of the algebra of propositions is solved. This problem is to construct all propositions whose truth is independent of the form of the variables. As might be expected this method will enable us to determine without the use of matrices the consistency and independence of propositions, except in the case of those fundamental properties, which taken together define consistency itself. In the discussion which follows (...) no limitations are placed on the meaning of the terms and the word proposition is used simply in the sense of a variable. If we were to say, for example, that our variables must be restricted to zero or one values, we would be introducing a limitation which would reduce the generality of our science. A logic may be false in the sense that its postulates lead to contradictory theorems, or it may be false in the sense that it lacks generality, and the situation is not saved by calling it a two-valued, or a three-valued logic, or a logic of “propositions,” or by designating it by some other euphuism.

Gary Kemp defends Realist approaches to the paradox of analysis. Other, prima facie equally viable approaches to this problem are the Nominalist one of Langford and Camap and the Conceptualist one of Prior and Stalnaker. In the context of a fuller survey focus is set on the realist attempt. This puts one in a better position to arbitrate between these approaches and give a more final assessment of the realist one, including an assessment of Kemp's defence of it. The Conceptualist (...) one, as it turns out, triumphs over the others, and is the basis for a Wittgensteinian vie w of the a priori which is analyzed in the second part of the paper. (shrink)

H.B.G. Casimir's life, interests and works are intertwined with the important developments that have taken place in physics during this century. This book was compiled by his friends and admirers in honour of his 80th birthday and concentrates mainly on Casimir's achievements in the field of physics, though without ignoring the peripheral areas of the history and philosophy of physics in which he was greatly interested. The book is divided into four parts. Part I describes Casimir's teachers, Ehrenfest, Bohr and (...) Pauli, and will be of general interest due to the key role which these physicists played in modern developments. The articles do give new facts and provide new insights into the history of modern physics. Part II consists of essays on recent developments in various areas of physics in which Casimir has taken an active interest, such as the modern concept of time, statistical foundations of electrodynamic theory and field theory. The subjects covered in Part III have been selected because of Casimir's efforts in the industrial research area of physics. They cover past, present and future expectations in research. (shrink)

Exceptional human experiences (EHEs) have garnered increasing research attention, particularly with regard to the characteristics and potential functional aspects of these experiences. The current study sought to replicate and expand upon previous research on EHEs by using a mixed-methods approach to examine the characteristics of EHEs in a large adult sample. The participants were 869 healthy adults who completed a survey that allowed participants to share both quantitative ratings and qualitative descriptions of EHEs. The results revealed that 96.7% of respondents (...) had experienced at least one EHE, and EHEs were generally rated as having a positive impact on the participants' lives. Participants reported a variety of EHEs, with two primary themes emerging in the qualitative analysis: perception and function of EHEs. The results suggest that EHEs may serve a positive, functional purpose in the lives of those who experience them. (shrink)

An outline of the life of Heraclides and his fragmentary writings (on the theory of matter, astronomy, ethical and religious topics) is followed by an attempt to reconstruct his thought. He emerges as not so much a profound thinker as a many-sided writer of considerable literary gifts and occasional flashes of brilliance.
