QUANTUM PHYSICS AND THEOLOGY: JOHN POLKINGHORNE ON THOUGHT EXPERIMENTS

Abstract Thought experimentation is part of accepted scientific practice, and this makes it surprising that philosophers of science did not seriously engage with it for a very long time. The situation changed in the 1990s, resulting in a highly intriguing debate over thought experiments. Initially, the discussion focused mostly on thought experiments in physics, philosophy, and mathematics. Other disciplines have since become the subject of interest. Yet, nothing substantial has been said about the role of thought experiments in nonphilosophical theology. This paper discusses the role of thought experiments in Christian theology in comparison to their role in quantum physics, as mentioned by John Polkinghorne in Quantum Physics and Theology. We first look briefly at the history of the inquiry into thought experiments and then at Polkinghorne's remarks about the role of thought experimentation in quantum physics and Christian eschatology. To determine the actual importance of thought experiments in Christian theology a number of new examples are introduced in a third step. In the light of these examples, in a fourth step, we address the question of what it is that explains the cognitive efficacy of thought experiments in quantum physics and Christian theology.     

BARBOUR'S TYPOLOGIES AND THE CONTEMPORARY DEBATE ON ISLAM AND SCIENCE

Abstract Despite various criticisms, Ian Barbour's fourfold classification of the possible relationships between religion and science remains influential. I compare Barbour's taxonomy with the theories of four authors who, in the last four decades, have addressed the relationship between science and religion from a Muslim perspective. The aim of my analysis is twofold. First, I offer a comparative perspective to the debate on science and Islam. Second, following Barbour's suggestion, I test the general applicability of his categories by comparing them with a discourse on science and religion that is not focused on Christianity. In the first section, I reconstruct Barbour's typologies, recalling some major objections to them, and arguing why despite the latter, Barbour's model is employed for the present analysis. I also reconstruct Barbour's parallel model for the relationships between different religions. In the second section, I reconstruct the discourse on science and religion developed by the Palestinian‐American scholar Ismail Raji al‐Faruqi. The third section is devoted to the ideas of the Persian‐American scholar Seyyed Hossein Nasr. In the fourth section, I examine the views of the Iranian author Mehdi Golshani. The fifth section reconstructs the theories of the Algerian author Nidhal Guessoum. In the final section, I argue that a generalized use of the “integration” concept to refer to the entire debate on Islam and science is unhelpful. While these positions do not appear to instantiate Barbourian integration of science and religion, they do move toward what Barbour (skeptically) describes as integration between religions.     

The Owl and the Ostrich: Reply to Sami Pihlström on Ethical Unthinkabilities and Philosophical Seriousness

Sami Pihlström argues in his “Ethical Unthinkabilities and Philosophical Seriousness” that there are some philosophical views that are so dangerous that we should not discuss them. He advances this argument with special reference to my (anti‐natalist) view that being brought into existence is always a serious harm. In response I argue: (a) that there are major flaws in his argument for the conclusion that we should not think about (purportedly) unthinkable views; and (b) that my views about the harm of coming into existence are in any event neither unthinkable nor dangerous.     

Gender differences in subjective well-being, self-esteem and psychosocial functioning in adolescents with symptoms of anxiety and depression: findings from the Nord-Trøndelag Health Study

Derdikman‐Eiron, R., Indredavik, M. S., Bratberg, G. H., Taraldsen, G., Bakken, I. J. & Colton, M. (2011). Gender differences in subjective well‐being, self‐esteem and psychosocial functioning in adolescents with symptoms of anxiety and depression: Findings from the Nord‐Trøndelag health study. Scandinavian Journal of Psychology52, 261–267. Gender differences in the prevalence of symptoms of anxiety and depression during adolescence are well documented. However, little attention has been given to differences in subjective well‐being, self‐esteem and psychosocial functioning between boys and girls with symptoms of anxiety and depression. The aim of this study was to investigate gender differences in the associations between such symptoms and subjective well‐being, self‐esteem, school functioning and social relations in adolescents. Data were taken from a major population‐based Norwegian study, the Nord‐Trøndelag Health study (HUNT), in which 8984 (91% of all invited) adolescents, aged 13–19 years, completed an extensive self‐report questionnaire. Although prevalence rates of symptoms of anxiety and depression were higher in girls than in boys, a significant interaction between gender and symptoms of anxiety and depression was found in respect of each of the following outcome variables: subjective well‐being, self‐esteem, academic problems, frequency of meeting friends and the feeling of not having enough friends. These interactions indicate that the associations between symptoms of anxiety and depression and lower subjective well‐being and self‐esteem, more academic problems in school and lower social functioning were stronger for boys than for girls. Our findings may contribute to an earlier assessment and more efficient treatment of male adolescent anxiety and depression.     

Are immigrants in the nursing industry at increased risk of bullying at work? A one‐year follow‐up study

The purpose of this study was to explore whether (a) immigrant health care workers (HCW) are more at risk of bullying at work than Danish staff members, (b) this association is increased by previous exposure to bullying and (c) immigrants experience more bullying from supervisors, colleagues and clients/residents. We analyzed cross-sectional baseline data from 5,635 health care students of whom 10.4% were immigrants, and conducted a prospective analysis by following 3,109 of these respondents during their first year of employment. More than a third of the respondents had previous experiences with bullying. The baseline analyses showed that immigrants are more at risk of being bullied during both their theoretical education and trainee periods than their Danish co-students. At follow-up we found that 9.1% of the total cohort had been exposed to bullying at work during their first year of employment, hereof 1.8% frequently. "Non-Western" immigrants had a significantly higher risk of exposure to bullying at work during follow-up than the Danish respondents independent of previous experience with bullying. Danish and immigrant health care workers were more exposed to bullying from co-workers than from supervisors with no statistically significant difference between the Danes and the immigrant groups. Both "Western" and "non-Western" respondents were more at risk of bullying from clients/residents than the Danish respondents.     

Exploring the enactment effect from an information processing view: What can we learn from serial position analyses?

The focus of the present article was to analyze processes that determine the enactment and age effect in a multi-trial free recall paradigm by looking at the serial position effects. In an experimental study (see Schatz et al 2010), the performance-enhancing effect of enactive encoding and repeated learning was tested with older and younger participants. As expected, there was a steady improvement of memory performance as a function of repeated learning regardless of age. In addition, enactive encoding led to a better memory performance than verbal encoding in both age groups. Furthermore, younger adults outperformed the elderly regardless of type of encoding. Analyses in the present article show that encoding by enacting seems to profit especially from remembering the last items of a presented list. Regarding age differences, younger outperformed older participants in nearly all item positions. The performance enhancement after task repetition is due to a higher amount of recalled items in the middle positions in a subject performed task (SPT) and a verbal task (VT) as well as the last positions of a learned list in VT.     

I know you're me, but who am I? Perspective taking and seeing the other in the self

Research examining the consequences of perspective-taking on cognition suggests that through perceiver–target overlap, perspective-taking can lead to greater valuing of targets, greater helping of targets, and a reduction in stereotyping of targets and the groups to which they belong. Research has also begun to focus more closely on the ways perceivers come to think and act like targets. This research, however evocative, is not conclusive. The current studies set out to provide firmer support. Reported here, two studies found that perspective-taking influences perceiver–target overlap, which mediates changes in self-concept (ratings of the self on researcher-related attributes and beliefs after taking the perspective of a researcher in Study 1 and attitudes toward African Americans after taking the perspective of a racist in Study 2). In the same studies, overlap simultaneously mediated valuing of the targets (target ratings on positive attributes in Study 1 and liking for the target in Study 2).     

Recognizing discrimination explicitly while denying it implicitly: Implicit social identity protection

Past research suggests that members of devalued groups recognize their groups are discriminated against. Do the implicit responses of members of these groups demonstrate the same pattern? We argue that they do not and that this is due to a motivated protection of members of devalued groups' social identity. Study 1 demonstrates that, at an explicit level African-Canadians recognize that their group is discriminated against, but at an implicit level African-Canadians think that most people like their group to a greater extent than do European-Canadians. Study 2 replicates this implicit finding with Muslim participants while demonstrating that, when affirmed, this group difference disappears. Study 3 demonstrates that implicit normative regard can predict collective action over and above implicit attitudes and explicit normative regard. The implications for changing the status quo are discussed.     

The effect of Obama saliency on individual-level racial bias: Silver bullet or smokescreen?

President Obama's election has been construed as a potentially positive force for intergroup relations, but this issue has not been previously addressed experimentally. In experiment 1, conducted 4-5 months after the election, White participants were primed with either President Obama or nature before completing a variety of race-related measures. Results indicated that priming Obama did not influence implicit racial bias or internal motivation to control prejudice. However, consistent with exemplar and symbolic racism theories, participants primed with President Obama expressed greater agreement with the tenets of symbolic racism and were more reluctant to accept the possibility that they personally harbored subtle racial bias. Experiment 2, conducted 21 months after the election, replicated the Obama effects from experiment 1 and showed that priming another Black exemplar (Oprah) also increased symbolic racism. Results suggest that highly successful Black exemplars currently serve as a smokescreen for symbolic and subtle racial biases.     

Transitional and steady-state choice behavior under an adjusting-delay schedule

Twelve rats made repeated choices on an adjusting-delay schedule between a smaller reinforcer (A) that was delivered immediately after a response and a larger reinforcer (B) that was delivered after a delay which increased or decreased by 20% depending on the subject's choices in successive blocks of trials. In two phases of the experiment (100 sessions and 40 sessions), reinforcer sizes were selected which enabled theoretical parameters expressing the rate of delay discounting and sensitivity to reinforcer size to be estimated from the ratio of the indifference delays obtained in the two phases. Indifference delays, calculated from adjusting delays in the last 10 sessions of each phase, were shorter when the sizes of A and B were 14 and 25 μl of a 0.6 M sucrose solution than when they were 25 and 100 μl of the same solution. The ratio of the indifference delays was significantly smaller than that predicted on the basis of an assumed linear relation between reinforcer size and instantaneous reinforcer value, consistent with a previous proposal that this relation may be hyperbolic in form. Estimates of the rate of delay discounting based on the ratio of the two indifference delays (mean, 0.08 s(-1)) were similar to values obtained previously using different intertemporal choice protocols. Estimates of the size-sensitivity parameter (mean 113 μl) were similar to estimates recently derived from performance on progressive-ratio schedules. In both phases of the experiment, adjusting delays in successive blocks of trials were analyzed using the Fourier transform. The power spectrum obtained from individual rats had a dominant frequency that corresponded to a period of oscillation of the adjusting delay between 30 and 100 trial blocks (mean, 78). Power in the dominant frequency band was highest in the early sessions of the first phase and declined with extended training. It is suggested that this experimental protocol may have utility in neurobehavioral studies of intertemporal choice.
