The hedgehog and the Borg: Common morality in bioethics

In this commentary, I critically discuss the respective views of Gert and Beauchamp–Childress on the nature of so-called common morality and its promise for enriching ethical reflection within the field of bioethics. Although I endorse Beauchamp and Childress’ shift from an emphasis on ethical theory as the source of moral norms to an emphasis on common morality, I question whether rouging up common morality to make it look like some sort of ultimate and universal foundation for morality, untouched by the dialectics of time and reflective equilibrium, was an equally good move. As for Gert’s magisterial conception of common morality, I conclude that certain elements of his system are controversial at best and woefully inadequate at worst. He has a tendency to find in common morality what he himself put there, and his highly restricted conception of duties of assistance strikes this reader as ad hoc, inadequately defended, and unworthy of a project whose goal is to lessen the amount of misery in the world.

When the Common Good Takes the Grand(est) Stage The Cosmic Common Good: Religious Grounds for Ecological Ethics,Daniel P. Scheid,Oxford University Press, 2016 (ISBN 978‐0‐19‐935943‐1), xvi + 248 pp., hb £19.99

Rooting itself in Catholic social teaching rather than theology of creation, this book develops a novel approach to Catholic ecological ethics. It argues that the traditional conception of the social common good should be fully broadened to encompass all creation, including abiota. Furthermore, the book suggests a comparative‐theological approach to ecological ethics through careful conversations with Buddhist, Hindu, and American Lakota conceptions and practices. While its vision of the cosmic common good at times appears too inclusive and perhaps ‘too good to be true’, this book is a valuable contribution to Christian ecological ethics and includes a fresh comparative‐theological take on ecological questions.     

Latent Trait Modeling with the Common beliefs Survey III: Using Item Response Theory to Evaluate an Irrational Beliefs Inventory

Assessment of irrational beliefs by such measures as the Common Beliefs Survey III (CBS) has traditionally relied upon classical test theory assumptions, in which the properties of specific test items are less important than the total test score as the aggregate of all item responses. An alternative approach using item response theory (IRT) methodology allows one to specify the parameters of difficulty and discrimination for each test item. Difficulty levels of CBS items range along a continuum of irrationality, the implied latent trait measured by responses to the questionnaire as a whole. We evaluated the CBS responses of 605 individuals from clinical and college settings, drawing from current and archival data. The original Likert scale ratings were recoded into dichotomous scores. Fourteen of the 54 items were highly or very highly discriminating in distinguishing respondents with high and low irrationality levels. However, discriminating items exhibited a very narrow range of difficulty; most functioned at a point a little above the halfway mark on the continuum of irrationality. Item characteristic curves and test information curves were very similar for female (n = 424) and male (n = 179) respondents. We derived a 4-item screening test for irrationality from our IRT analyses of the 54 CBS items. Further test development, focused on the selection and scaling of items with a much broader range of difficulty, would facilitate evaluation of the hierarchical structure of irrational beliefs. Portions of this paper were presented at the 39th Annual Convention of the Association for Behavioral and Cognitive Therapies, Washington, DC, November, 2005.     

Intolerance to ambient odors at an early stage of pregnancy

Adverse reactions to ambient odorous and pungent substances in daily activities among pregnant women who are half-way through pregnancy, and changes in odor perception at predominantly an early stage of pregnancy motivated the present study of odor intolerance at an early pregnancy stage. Ninety-five women averaging gestational week 11 and 102 non-pregnant women were compared with the Chemical Sensitivity Scale for Sensory Hyperreactivity (CSS-SHR). General environmental intolerance was assessed with items from the Noise Sensitivity Scale that are analogous to the CSS-SHR ("NSS-SHR"). Pregnant women were found to have higher scores on the CSS-SHR, but not on the "NSS-SHR". This suggests an odor intolerance that affects pregnant women's daily activities, which appears not to be due to a general environmental intolerance. The effect size of pregnancy on CSS-SHR score is larger in the present study of early pregnancy than in the previous study of women half-way through pregnancy.     

Cut-free common knowledge

Starting off from the infinitary system for common knowledge over multi-modal epistemic logic presented in [L. Alberucci, G. Jäger, About cut elimination for logics of common knowledge, Annals of Pure and Applied Logic 133 (2005) 73–99], we apply the finite model property to “finitize” this deductive system. The result is a cut-free, sound and complete sequent calculus for common knowledge.     

Children's (and Adults') Production Adjustments to Generic and Particular Listener Needs

Adults design utterances to match listeners' informational needs by making both “generic” adjustments (e.g., mentioning atypical more often than typical information) and “particular” adjustments tailored to their specific interlocutor (e.g., including things that their addressee cannot see). For children, however, relevant evidence is mixed. Three experiments investigated how generic and particular factors affect children's production. In Experiment 1, 4‐ to 5‐year‐old children and adults described typical and atypical instrument events to a silent listener who could either see or not see the events. In later extensions, participants described the same events to either a silent (Experiment 2) or an interactive (Experiment 3) addressee with a specific goal. Both adults and 4‐ to 5‐year‐olds performed generic adjustments but, unlike adults, children made listener‐particular adjustments inconsistently. These and prior findings can be explained by assuming that particular adjustments can be costlier for children to implement compared to generic adjustments.     

Natural Compatibilism,Indeterminism, and Intrusive Metaphysics

The claim that common sense regards free will and moral responsibility as compatible with determinism has played a central role in both analytic and experimental philosophy. In this paper, we show that evidence in favor of this “natural compatibilism” is undermined by the role that indeterministic metaphysical views play in how people construe deterministic scenarios. To demonstrate this, we re-examine two classic studies that have been used to support natural compatibilism. We find that although people give apparently compatibilist responses, this is largely explained by the fact that people import an indeterministic metaphysics into deterministic scenarios when making judgments about freedom and responsibility. We conclude that judgments based on these scenarios are not reliable evidence for natural compatibilism.     

Modeling self on others: An import theory of subjectivity and selfhood

This paper outlines an Import Theory of subjectivity and selfhood. Import theory claims that subjectivity is initially perceived as a key feature of other minds before it then becomes imported from other minds to own minds whereby it lays the ground for mental selfhood. Import theory builds on perception-production matching, which in turn draws on both representational mechanisms and social practices. Representational mechanisms rely on common coding of perception and production. Social practices rely on action mirroring in dyadic interactions. The interplay between mechanisms and practices gives rise to model self on others. Individuals become intentional agents in virtue of perceiving others mirroring themselves. The outline of the theory is preceded by an introductory section that locates import theory in the broader context of competing approaches, and it is followed by a concluding section that assesses import theory in terms of empirical evidence and explanatory power.     

Another view of “we”: Majority and minority group perspectives on a common ingroup identity

Drawing on the evidence of the role of social categorisation and identity in the development and maintenance of intergroup biases, research on the Common Ingroup Identity Model (Gaertner & Dovidio, 2000 Gaertner, S. L. and Dovidio, J. F. 2000. Reducing intergroup bias: The Common Ingroup Identity Model, Philadelphia, PA: The Psychology Press.  [Google Scholar]) has investigated how modifying the ways that the self and others are categorised can reduce prejudice and discrimination. In this article, we review more recent research that extends our initial formulation of the model by considering more fully alternative forms of recategorisation (a dual identity as well as a one-group representation), the different preferences of majority and minority groups for these different forms of recategorised representations, and the potential implications of these different preferences on the content of intergroup interaction and on the possibilities for social change towards equality.
