Aristotle on Universal Quantification: A Study from the Point of View of Game Semantics

In this paper we provide an interpretation of Aristotle's rule for the universal quantifier in Topics Θ 157^a34–37 and 160^b1–6 in terms of Paul Lorenzen's dialogical logic. This is meant as a contribution to the rehabilitation of the role of dialectic within the Organon. After a review of earlier views of Aristotle on quantification, we argue that this rule is related to the dictum de omni in Prior Analytics A 24^b28–29. This would be an indication of the dictum’s origin in the context of dialectical games. One consequence of our approach is a novel explanation of the doctrine of the existential import of the quantifiers in dialectical terms. After a brief survey of Lorenzen's dialogical logic, we offer a set of rules for dialectical games based on previous work by Castelnérac and Marion, to which we add here the rule for the universal quantifier, as interpreted in terms of its counterpart in dialogical logic. We then give textual evidence of the use of that rule in Plato's dialogues, thus showing that Aristotle only made explicit a rule already implicit in practice, while providing a new interpretation of ‘epagogic’ arguments. Finally, we show how a proper understanding of that rule involves further rules concerning counterexamples and delaying tactics, stressing again the parallels with dialogical logic.     

A Comparison of Rorschach Records of Three Multiple Personalities

Inter- and intra-protocol comparisons among the Rorschachs of three authenticated cases of multiple personality were presented. The original or primary personalities seemed reasonably complex but, as successive personalities emerged, a definite tendency toward simplification was noted. A theoretical explanation for this phenomenon was advanced.     

An efficacious theory-based intervention for stepfamilies

This article evaluates the efficacy of the Oregon model of Parent Management Training (PMTO) in the stepfamily context. Sixty-seven of 110 participants in the Marriage and Parenting in Stepfamilies (MAPS) program received a PMTO-based intervention. Participants in the randomly assigned experimental group displayed a large effect in benefits to effective parenting practices with resultant decreases in child noncompliance and in home and school problem behaviors. MAPS findings replicate and extend those of the Oregon Divorce Study with single mothers while employing a similar multiple-method, multiple-measure randomized design, with Intent-to-Treat and structural equation modeling analyses. We discuss direct and indirect effects on distal outcomes and the generalizability of PMTO to differing family contexts.     

Early development of delinquency within divorced families: evaluating a randomized preventive intervention trial

This paper reports on an experimental test of coercion theory early onset model of delinquency. Results are from the Oregon Divorce Study-II, a randomized preventive intervention trial with a sample of 238 recently separated mothers and their sons in early elementary school. The objective was to experimentally manipulate parenting variables hypothesized to influence development of delinquent behaviors. Multiple-method assessment spanned 36 months. Because the intervention focused on parent training, we expected that any intervention effects on changes in child outcomes would be mediated by hypothesized intervening mechanisms. Linear growth models showed significantly greater reduction in boys' delinquency and deviant peer affiliation in the experimental group relative to the controls. Subsequent models using no method overlap in constructs demonstrated that the intervention effect on delinquency operated through growth in parenting and reduction in deviant peer affiliation.     

The influence of maternal employment on gender role attitudes of men and women

The effects of maternal employment on young adults' gender role attitudes were assessed. A random sample of 111 males and 131 females was surveyed [179 Whites (74.0%), 35 Blacks (14.5%), and 28 others (typically Asian-Americans, 11.5%)]. Results varied depending on which gender role attitudes were being examined. With respect to approval of mother working outside the home, only the respondent's age when his or her mother began working was significant. However, this relationship was not found when assessing attitudes about the separate spheres ideology. Thus, it appears that attitudes toward women working depend on whether the respondent's mother worked, whereas beliefs about adult male—female equality do not appear to be as closely related to childhood experiences. Mothers' occupations were unrelated to all of the attitudes examined, as were her children's perceptions of how satisfied she was with her primary work role (employed or nonemployed). Finally, the only significant predictors of gender role attitudes to be discovered were the sex of respondent and attendance at religious services. Females expressed more egalitarian gender role attitudes, and those who reported frequent attendance at religious services were more likely to endorse traditional gender roles.This article was part of a master's thesis conducted at the University of Virginia by the first author.We gratefully acknowledge the assistance of Paul W. Kingston in proposal formulation and survey construction, Lance C. Bloom in data collection, and the helpful comments made by the anonymous reviewers ofSex Roles.     

Précis of Evolution in Four Dimensions

In his theory of evolution, Darwin recognized that the conditions of life play a role in the generation of hereditary variations, as well as in their selection. However, as evolutionary theory was developed further, heredity became identified with genetics, and variation was seen in terms of combinations of randomly generated gene mutations. We argue that this view is now changing, because it is clear that a notion of hereditary variation that is based solely on randomly varying genes that are unaffected by developmental conditions is an inadequate basis for evolutionary theories. Such a view not only fails to provide satisfying explanations of many evolutionary phenomena, it also makes assumptions that are not consistent with the data that are emerging from disciplines ranging from molecular biology to cultural studies. These data show that the genome is far more responsive to the environment than previously thought, and that not all transmissible variation is underlain by genetic differences. In Evolution in Four Dimensions (2005) we identify four types of inheritance (genetic, epigenetic, behavioral, and symbol-based), each of which can provide variations on which natural selection will act. Some of these variations arise in response to developmental conditions, so there are Lamarckian aspects to evolution. We argue that a better insight into evolutionary processes will result from recognizing that transmitted variations that are not based on DNA differences have played a role. This is particularly true for understanding the evolution of human behavior, where all four dimensions of heredity have been important.     

Leadership Image-Building: After Clinton and Watergate

Leadership images are built collectively by leaders and their relevantconstituencies—elected officials, the news media, and the public. The process of buildingleadership image rests on prior expectations about the leader, policy outputs, the course ofevents, and the disposition of political resources. In building images of leadership, each of thethree constituencies puts more weight on some aspects of image-building than on others: Thepublic sees the president primarily in terms of his previous behavior, the media view thepresident through the lens of immediate events, and other elected officials focus on politicalresources. One of the president's most important resources is his public image. It can helphim to maintain the loyalty of other officials, which in turn contributes to balanced newscoverage, even in times of crisis. President Clinton was able to preserve his public image throughthe impeachment debacle in large part because of low public expectations about his personalmoral behavior and satisfaction with his economic leadership. Conversely, President Nixon wasforced to resign because of high public expectations about his personal probity anddisappointment with his management of the economy.
