ENTRUSTING THE LIFE THAT HAS EVOLVED: A RESPONSE TO MICHAEL RUSE'S RUSE

Abstract. This piece challenges Michael Ruse on three points: (1) The charge that Christian myth and doctrine are incredible fails to take into account the scholarship that has clarified the genre to which myth belongs and its function. (2) Naturalistic explanations, like Ruse's, have fully as much difficulty dealing with questions of purpose and evil as religion does. (3) The concept of "deception" has a number of inherent problems that Ruse fails to consider, of which the chief is that it requires a certainty about truth and falsity that Ruse cannot and does not claim to possess.     

Circular definitions,circular explanations,and infinite regresses

This paper discusses some of the ways in which circular definitions and circular explanations entail or fail to entail infinite regresses. And since not all infinite regresses are vicious, a few criteria of viciousness are examined in order to determine when the entailment of a regress refutes a circular definition or a circular explanation.I would like to thank Professors Robert Tully, Howard Sobel, and Derek Allen for their constructive comments.     

Restricted multidimensional scaling models for asymmetric proximities

Restricted multidimensional scaling models [Bentler & Weeks, 1978] allowing constraints on parameters, are extended to the case of asymmetric data. Separate functions are used to model the symmetric and antisymmetric parts of the data. The approach is also extended to the case in which data are presumed to be linearly related to squared distances. Examples of several models are provided, using journal citation data. Possible extensions of the models are considered. This research was supported in part by USPHS Grant 0A01070, P. M. Bentler, principal investigator, and NIMH Grant MH-24819, E. J. Anthony and J. Worland, principal investigators. The authors wish to thank E. W. Holman and several anonymous reviewers for their valuable suggestions concerning this research.     

An operant analysis of human altruistic responding

Human altruistic responding (called give responding), which delivered a reinforcer to someone other than the responder, was compared to responding where the responder was the recipient of the reinforcer (called earn responding). The same type of response (button pressing), the same reinforcer (a point representing a penny), and the same reinforcer contingency (a 40-response fixed-ratio schedule) were used for both give and earn responding. Since points representing pennies were used to reinforce give and earn responding, responding for points not worth money was also assessed. Give, earn, and point responding were arranged as concurrent incompatible operants. Lowest rates were obtained for point responding. Compared to earn responding, give responding occurred at lower rates, was more susceptible to cessation when point responding was possible, extinguished more rapidly in the absence of money, and produced less responding during reconditioning compared to conditioning when reconditioning followed a period of nonreinforcement. Give responding was less when it reduced the giver's opportunity to earn. Finally, histories of getting reinforcement from others were shown to determine give responding.     

大学生对乞丐的态度及其与利他主义的相关研究

乞丐问题是现今我国颇受关注的社会问题。本文以大学生为被试,使用自编《大学生对乞丐态度问卷》,探讨了大学生乃至大众对乞丐错综复杂的态度。结果显示：大学生对乞丐的态度较为复杂,通过因素分析我们得出了5种态度,即尊重、漠然、同情、歧视和权利认同。我们还探讨了大学生对乞丐的不同态度之间、与利他主义倾向的相关关系,以及这些关系的产生原因。     

New Evolutionary Perspectives on Altruism: Multilevel-Selection and Costly-Signaling Theories

Social psychological theories tend to be primarily concerned with the immediate causes of altruism, whereas evolutionary explanations focus more on the origins and ultimate functions of altruistic behavior. Recent developments in the evolutionary psychology of altruism promise an even richer understanding of this important category of social behaviors. Specifically, new perspectives offered by multilevel-selection theory and costly-signaling theory may help to shed light on some of the more problematic issues in the study of altruism.     

Symbioses Can Transcend Particularisms: A Memoir of Friendship with Ralph Wendell Burhoe

Ralph Burho's paradigmatic scientific innovation is the extension of the concept of symbiosis to coadapted human genotypes and "culturetypes," centered on religion. Civilization also requires a coexistent secular arena, where religion's nearness may help prevent our natural synergistic instrumentalizations of each other from degrading to losses of respect for one another as responsible free agents. The mixed messages in the Bible's diverse stories help to preserve a richness of choices in memory as we navigate history. We science-and-religion theorists should expand our cademic base to include economics, politics, literature, and other areas, while emulating Ralph's wise and good-humored ways of drawing us together and affecting our lives.
